+# Core Pack Dependencies
+
+**Philosophy:** The core pack has **zero runtime dependencies** beyond standard system utilities.
+
+## Why Zero Dependencies?
+
+1. **Portability:** Works in any environment with standard Unix utilities
+2. **Reliability:** No version conflicts, no package installation failures
+3. **Security:** Minimal attack surface, no third-party library vulnerabilities
+4. **Performance:** Fast startup, no runtime initialization overhead
+5. **Simplicity:** Easy to audit, test, and maintain
+
+## Required System Utilities
+
+All core pack actions rely only on utilities available in standard Linux/Unix environments:
+
+| Utility | Purpose | Used By |
+|---------|---------|---------|
+| `bash` | Shell scripting | All shell actions |
+| `jq` | JSON parsing/generation | All actions (parameter handling) |
+| `curl` | HTTP client | `http_request.sh` |
+| Standard Unix tools | Text processing, file operations | Various actions |
+
+These utilities are:
+- ✅ Pre-installed in all Attune worker containers
+- ✅ Standard across Linux distributions
+- ✅ Stable, well-tested, and widely used
+- ✅ Available via package managers if needed
+
+## No Runtime Dependencies
+
+The core pack **does not require:**
+- ❌ Python interpreter or packages
+- ❌ Node.js runtime or npm modules
+- ❌ Ruby, Perl, or other scripting languages
+- ❌ Third-party libraries or frameworks
+- ❌ Package installations at runtime
+
+## Action Implementation Guidelines
+
+### ✅ Preferred Approaches
+
+**Use bash + standard utilities:**
+```bash
+#!/bin/bash
+# Read params with jq
+INPUT=$(cat)
+PARAM=$(echo "$INPUT" | jq -r '.param // "default"')
+
+# Process with standard tools
+RESULT=$(echo "$PARAM" | tr '[:lower:]' '[:upper:]')
+
+# Output with jq
+jq -n --arg result "$RESULT" '{result: $result}'
+```
+
+**Use curl for HTTP:**
+```bash
+# Make HTTP requests with curl
+curl -s -X POST "$URL" \
+    -H "Content-Type: application/json" \
+    -d '{"key": "value"}'
+```
+
+**Use jq for JSON processing:**
+```bash
+# Parse JSON responses
+echo "$RESPONSE" | jq '.data.items[] | .name'
+
+# Generate JSON output
+jq -n \
+    --arg status "success" \
+    --argjson count 42 \
+    '{status: $status, count: $count}'
+```
+
+### ❌ Avoid
+
+**Don't add runtime dependencies:**
+```bash
+# ❌ DON'T DO THIS
+pip install requests
+python3 script.py
+
+# ❌ DON'T DO THIS
+npm install axios
+node script.js
+
+# ❌ DON'T DO THIS
+gem install httparty
+ruby script.rb
+```
+
+**Don't use language-specific features:**
+```python
+# ❌ DON'T DO THIS in core pack
+#!/usr/bin/env python3
+import requests  # External dependency!
+response = requests.get(url)
+```
+
+Instead, use bash + curl:
+```bash
+# ✅ DO THIS in core pack
+#!/bin/bash
+response=$(curl -s "$url")
+```
+
+## When Runtime Dependencies Are Acceptable
+
+For **custom packs** (not core pack), runtime dependencies are fine:
+- ✅ Pack-specific Python libraries (installed in pack virtualenv)
+- ✅ Pack-specific npm modules (installed in pack node_modules)
+- ✅ Language runtimes (Python, Node.js) for complex logic
+- ✅ Specialized tools for specific integrations
+
+The core pack serves as a foundation with zero dependencies. Custom packs can have dependencies managed via:
+- `requirements.txt` for Python packages
+- `package.json` for Node.js modules
+- Pack runtime environments (isolated per pack)
+
+## Migration from Runtime Dependencies
+
+If an action currently uses a runtime dependency, consider:
+
+1. **Can it be done with bash + standard utilities?**
+   - Yes → Rewrite in bash
+   - No → Consider if it belongs in core pack
+
+2. **Is the functionality complex?**
+   - Simple HTTP/JSON → Use curl + jq
+   - Complex API client → Move to custom pack
+
+3. **Is it a specialized integration?**
+   - Yes → Move to integration-specific pack
+   - No → Keep in core pack with bash implementation
+
+### Example: http_request Migration
+
+**Before (Python with dependency):**
+```python
+#!/usr/bin/env python3
+import requests  # ❌ External dependency
+
+response = requests.get(url, headers=headers)
+print(response.json())
+```
+
+**After (Bash with standard utilities):**
+```bash
+#!/bin/bash
+# ✅ No dependencies beyond curl + jq
+
+response=$(curl -s -H "Authorization: Bearer $TOKEN" "$URL")
+echo "$response" | jq '.'
+```
+
+## Testing Without Dependencies
+
+Core pack actions can be tested anywhere with standard utilities:
+
+```bash
+# Local testing (no installation needed)
+echo '{"param": "value"}' | ./action.sh
+
+# Docker testing (minimal base image)
+docker run --rm -i alpine:latest sh -c '
+    apk add --no-cache bash jq curl &&
+    /bin/bash < action.sh
+'
+
+# CI/CD testing (standard tools available)
+./action.sh < test-params.json
+```
+
+## Benefits Realized
+
+### For Developers
+- No dependency management overhead
+- Immediate action execution (no runtime setup)
+- Easy to test locally
+- Simple to audit and debug
+
+### For Operators
+- No version conflicts between packs
+- No package installation failures
+- Faster container startup
+- Smaller container images
+
+### For Security
+- Minimal attack surface
+- No third-party library vulnerabilities
+- Easier to audit (standard tools only)
+- No supply chain risks
+
+### For Performance
+- Fast action startup (no runtime initialization)
+- Low memory footprint
+- No package loading overhead
+- Efficient resource usage
+
+## Standard Utility Reference
+
+### jq (JSON Processing)
+```bash
+# Parse input
+VALUE=$(echo "$JSON" | jq -r '.key')
+
+# Generate output
+jq -n --arg val "$VALUE" '{result: $val}'
+
+# Transform data
+echo "$JSON" | jq '.items[] | select(.active)'
+```
+
+### curl (HTTP Client)
+```bash
+# GET request
+curl -s "$URL"
+
+# POST with JSON
+curl -s -X POST "$URL" \
+    -H "Content-Type: application/json" \
+    -d '{"key": "value"}'
+
+# With authentication
+curl -s -H "Authorization: Bearer $TOKEN" "$URL"
+```
+
+### Standard Text Tools
+```bash
+# grep - Pattern matching
+echo "$TEXT" | grep "pattern"
+
+# sed - Text transformation
+echo "$TEXT" | sed 's/old/new/g'
+
+# awk - Text processing
+echo "$TEXT" | awk '{print $1}'
+
+# tr - Character translation
+echo "$TEXT" | tr '[:lower:]' '[:upper:]'
+```
+
+## Future Considerations
+
+The core pack will:
+- ✅ Continue to have zero runtime dependencies
+- ✅ Use only standard Unix utilities
+- ✅ Serve as a reference implementation
+- ✅ Provide foundational actions for workflows
+
+Custom packs may:
+- ✅ Have runtime dependencies (Python, Node.js, etc.)
+- ✅ Use specialized libraries for integrations
+- ✅ Require specific tools or SDKs
+- ✅ Manage dependencies via pack environments
+
+## Summary
+
+**Core Pack = Zero Dependencies + Standard Utilities**
+
+This philosophy ensures the core pack is:
+- Portable across all environments
+- Reliable without version conflicts
+- Secure with minimal attack surface
+- Performant with fast startup
+- Simple to test and maintain
+
+For actions requiring runtime dependencies, create custom packs with proper dependency management via `requirements.txt`, `package.json`, or similar mechanisms.

+# Core Pack Setup Guide
+
+This guide explains how to set up and load the Attune core pack into your database.
+
+## Overview
+
+The **core pack** is Attune's built-in system pack that provides essential automation components including:
+
+- **Timer Triggers**: Interval-based, cron-based, and datetime triggers
+- **Basic Actions**: Echo, sleep, noop, and HTTP request actions
+- **Built-in Sensors**: Interval timer sensor for time-based automation
+
+The core pack must be loaded into the database before it can be used in rules and workflows.
+
+## Prerequisites
+
+Before loading the core pack, ensure:
+
+1. **PostgreSQL is running** and accessible
+2. **Database migrations are applied**: `sqlx migrate run`
+3. **Python 3.8+** is installed (for the loader script)
+4. **Required Python packages** are installed:
+   ```bash
+   pip install psycopg2-binary pyyaml
+   ```
+
+## Loading Methods
+
+### Method 1: Python Loader Script (Recommended)
+
+The Python loader script reads the pack YAML files and creates database entries automatically.
+
+**Usage:**
+```bash
+# From the project root
+python3 scripts/load_core_pack.py
+
+# With custom database URL
+python3 scripts/load_core_pack.py --database-url "postgresql://user:pass@localhost:5432/attune"
+
+# With custom pack directory
+python3 scripts/load_core_pack.py --pack-dir ./packs
+```
+
+**What it does:**
+- Reads `pack.yaml` for pack metadata
+- Loads all trigger definitions from `triggers/*.yaml`
+- Loads all action definitions from `actions/*.yaml`
+- Loads all sensor definitions from `sensors/*.yaml`
+- Creates or updates database entries (idempotent)
+- Uses transactions (all-or-nothing)
+
+**Output:**
+```
+============================================================
+Core Pack Loader
+============================================================
+
+→ Loading pack metadata...
+✓ Pack 'core' loaded (ID: 1)
+
+→ Loading triggers...
+  ✓ Trigger 'core.intervaltimer' (ID: 1)
+  ✓ Trigger 'core.crontimer' (ID: 2)
+  ✓ Trigger 'core.datetimetimer' (ID: 3)
+
+→ Loading actions...
+  ✓ Action 'core.echo' (ID: 1)
+  ✓ Action 'core.sleep' (ID: 2)
+  ✓ Action 'core.noop' (ID: 3)
+  ✓ Action 'core.http_request' (ID: 4)
+
+→ Loading sensors...
+  ✓ Sensor 'core.interval_timer_sensor' (ID: 1)
+
+============================================================
+✓ Core pack loaded successfully!
+============================================================
+  Pack ID: 1
+  Triggers: 3
+  Actions: 4
+  Sensors: 1
+```
+
+### Method 2: SQL Seed Script
+
+For simpler setups or CI/CD, you can use the SQL seed script directly.
+
+**Usage:**
+```bash
+psql $DATABASE_URL -f scripts/seed_core_pack.sql
+```
+
+**Note:** The SQL script may not include all pack metadata and is less flexible than the Python loader.
+
+### Method 3: CLI (Future)
+
+Once the CLI pack management commands are fully implemented:
+
+```bash
+attune pack register ./packs/core
+```
+
+## Verification
+
+After loading, verify the core pack is available:
+
+### Using CLI
+```bash
+# List all packs
+attune pack list
+
+# Show core pack details
+attune pack show core
+
+# List core pack actions
+attune action list --pack core
+
+# List core pack triggers
+attune trigger list --pack core
+```
+
+### Using API
+```bash
+# Get pack info
+curl http://localhost:8080/api/v1/packs/core | jq
+
+# List actions
+curl http://localhost:8080/api/v1/packs/core/actions | jq
+
+# List triggers
+curl http://localhost:8080/api/v1/packs/core/triggers | jq
+```
+
+### Using Database
+```sql
+-- Check pack exists
+SELECT * FROM attune.pack WHERE ref = 'core';
+
+-- Count components
+SELECT 
+    (SELECT COUNT(*) FROM attune.trigger WHERE pack_ref = 'core') as triggers,
+    (SELECT COUNT(*) FROM attune.action WHERE pack_ref = 'core') as actions,
+    (SELECT COUNT(*) FROM attune.sensor WHERE pack_ref = 'core') as sensors;
+```
+
+## Testing the Core Pack
+
+### 1. Test Actions Directly
+
+Test actions using environment variables:
+
+```bash
+# Test echo action
+export ATTUNE_ACTION_MESSAGE="Hello, Attune!"
+export ATTUNE_ACTION_UPPERCASE=false
+./packs/core/actions/echo.sh
+
+# Test sleep action
+export ATTUNE_ACTION_SECONDS=2
+export ATTUNE_ACTION_MESSAGE="Sleeping..."
+./packs/core/actions/sleep.sh
+
+# Test HTTP request action
+export ATTUNE_ACTION_URL="https://httpbin.org/get"
+export ATTUNE_ACTION_METHOD="GET"
+python3 packs/core/actions/http_request.py
+```
+
+### 2. Run Pack Test Suite
+
+```bash
+# Run comprehensive test suite
+./packs/core/test_core_pack.sh
+```
+
+### 3. Create a Test Rule
+
+Create a simple rule to test the core pack integration:
+
+```bash
+# Create a rule that echoes every 10 seconds
+attune rule create \
+  --name "test_timer_echo" \
+  --trigger "core.intervaltimer" \
+  --trigger-config '{"unit":"seconds","interval":10}' \
+  --action "core.echo" \
+  --action-params '{"message":"Timer triggered!"}' \
+  --enabled
+```
+
+## Updating the Core Pack
+
+To update the core pack after making changes:
+
+1. Edit the relevant YAML files in `packs/core/`
+2. Re-run the loader script:
+   ```bash
+   python3 scripts/load_core_pack.py
+   ```
+3. The loader will update existing entries (upsert)
+
+## Troubleshooting
+
+### "Failed to connect to database"
+- Verify PostgreSQL is running: `pg_isready`
+- Check `DATABASE_URL` environment variable
+- Test connection: `psql $DATABASE_URL -c "SELECT 1"`
+
+### "pack.yaml not found"
+- Ensure you're running from the project root
+- Check the `--pack-dir` argument points to the correct directory
+- Verify `packs/core/pack.yaml` exists
+
+### "ModuleNotFoundError: No module named 'psycopg2'"
+```bash
+pip install psycopg2-binary pyyaml
+```
+
+### "Pack loaded but not visible in API"
+- Restart the API service to reload pack data
+- Check pack is enabled: `SELECT enabled FROM attune.pack WHERE ref = 'core'`
+
+### Actions not executing
+- Verify action scripts are executable: `chmod +x packs/core/actions/*.sh`
+- Check worker service is running and can access the packs directory
+- Verify runtime configuration is correct
+
+## Development Workflow
+
+When developing new core pack components:
+
+1. **Add new action:**
+   - Create `actions/new_action.yaml` with metadata
+   - Create `actions/new_action.sh` (or `.py`) with implementation
+   - Make script executable: `chmod +x actions/new_action.sh`
+   - Test locally: `export ATTUNE_ACTION_*=... && ./actions/new_action.sh`
+   - Load into database: `python3 scripts/load_core_pack.py`
+
+2. **Add new trigger:**
+   - Create `triggers/new_trigger.yaml` with metadata
+   - Load into database: `python3 scripts/load_core_pack.py`
+   - Create sensor if needed
+
+3. **Add new sensor:**
+   - Create `sensors/new_sensor.yaml` with metadata
+   - Create `sensors/new_sensor.py` with implementation
+   - Load into database: `python3 scripts/load_core_pack.py`
+   - Restart sensor service
+
+## Environment Variables
+
+The loader script supports the following environment variables:
+
+- `DATABASE_URL` - PostgreSQL connection string
+  - Default: `postgresql://postgres:postgres@localhost:5432/attune`
+  - Example: `postgresql://user:pass@db.example.com:5432/attune`
+
+- `ATTUNE_PACKS_DIR` - Base directory for packs
+  - Default: `./packs`
+  - Example: `/opt/attune/packs`
+
+## CI/CD Integration
+
+For automated deployments:
+
+```yaml
+# Example GitHub Actions workflow
+- name: Load Core Pack
+  run: |
+    python3 scripts/load_core_pack.py \
+      --database-url "${{ secrets.DATABASE_URL }}"
+  env:
+    DATABASE_URL: ${{ secrets.DATABASE_URL }}
+```
+
+## Next Steps
+
+After loading the core pack:
+
+1. **Create your first rule** using core triggers and actions
+2. **Enable sensors** to start generating events
+3. **Monitor executions** via the API or Web UI
+4. **Explore pack documentation** in `README.md`

+## Testing Actions
+
+Actions receive parameters via environment variables prefixed with `ATTUNE_ACTION_`.
+
+### Test `core.echo`
+
+```bash
+# Basic echo
+export ATTUNE_ACTION_MESSAGE="Hello, Attune!"
+./packs/core/actions/echo.sh
+
+# With uppercase conversion

+  "url": "https://httpbin.org/get",
+  "success": true
+}
+```
+
+---
+
+## Testing Sensors
+
+Sensors receive configuration via environment variables prefixed with `ATTUNE_SENSOR_`.
+
+### Test `core.interval_timer_sensor`
+
+```bash
+# Create test trigger instances JSON
+export ATTUNE_SENSOR_TRIGGERS='[
+  {
+    "id": 1,
+    "ref": "core.intervaltimer",
+    "config": {
+      "unit": "seconds",
+      "interval": 5
+    }
+  }
+]'
+
+# Run sensor (will output events every 5 seconds)
+python3 ./packs/core/sensors/interval_timer_sensor.py
+```
+
+**Expected Output:**
+```
+Interval Timer Sensor started (check_interval=1s)
+{"type": "interval", "interval_seconds": 5, "fired_at": "2024-01-20T12:00:00Z", "execution_count": 1, "sensor_ref": "core.interval_timer_sensor", "trigger_instance_id": 1, "trigger_ref": "core.intervaltimer"}
+{"type": "interval", "interval_seconds": 5, "fired_at": "2024-01-20T12:00:05Z", "execution_count": 2, "sensor_ref": "core.interval_timer_sensor", "trigger_instance_id": 1, "trigger_ref": "core.intervaltimer"}
+...
+```
+
+Press `Ctrl+C` to stop the sensor.
+
+---
+
+## Testing with Multiple Trigger Instances
+
+```bash
+# Test multiple timers
+export ATTUNE_SENSOR_TRIGGERS='[
+  {
+    "id": 1,
+    "ref": "core.intervaltimer",
+    "config": {"unit": "seconds", "interval": 3}
+  },
+  {
+    "id": 2,
+    "ref": "core.intervaltimer",
+    "config": {"unit": "seconds", "interval": 5}
+  },
+  {
+    "id": 3,
+    "ref": "core.intervaltimer",
+    "config": {"unit": "seconds", "interval": 10}
+  }
+]'
+
+python3 ./packs/core/sensors/interval_timer_sensor.py
+```
+
+You should see events firing at different intervals (3s, 5s, 10s).
+
+---
+
+## Validation Tests
+
+### Validate YAML Schemas
+
+```bash
+# Install yamllint (optional)
+pip install yamllint
+
+# Validate all YAML files
+yamllint packs/core/**/*.yaml
+```
+
+### Validate JSON Schemas
+
+```bash
+# Check parameter schemas are valid JSON Schema
+cat packs/core/actions/http_request.yaml | grep -A 50 "parameters:" | python3 -c "
+import sys, yaml, json
+data = yaml.safe_load(sys.stdin)
+print(json.dumps(data, indent=2))
+"
+```
+
+---
+
+## Error Testing
+
+### Test Invalid Parameters
+
+```bash
+# Invalid seconds value for sleep
+export ATTUNE_ACTION_SECONDS=-1
+./packs/core/actions/sleep.sh
+# Expected: ERROR: seconds must be between 0 and 3600
+
+# Invalid exit code for noop
+export ATTUNE_ACTION_EXIT_CODE=999
+./packs/core/actions/noop.sh
+# Expected: ERROR: exit_code must be between 0 and 255
+
+# Missing required parameter for HTTP request
+unset ATTUNE_ACTION_URL
+python3 ./packs/core/actions/http_request.py
+# Expected: ERROR: Required parameter 'url' not provided
+```
+
+---
+
+## Performance Testing
+
+### Measure Action Execution Time
+
+```bash
+# Echo action
+time for i in {1..100}; do
+  export ATTUNE_ACTION_MESSAGE="Test $i"
+  ./packs/core/actions/echo.sh > /dev/null
+done
+
+# HTTP request action
+time for i in {1..10}; do
+  export ATTUNE_ACTION_URL="https://httpbin.org/get"
+  python3 ./packs/core/actions/http_request.py > /dev/null
+done
+```
+
+---
+
+## Integration Testing (with Attune Services)
+
+### Prerequisites
+
+```bash
+# Start Attune services
+docker-compose up -d postgres rabbitmq redis
+
+# Run migrations
+sqlx migrate run
+
+# Load core pack (future)
+# attune pack load packs/core
+```
+
+### Test Action Execution via API
+
+```bash
+# Create execution manually
+curl -X POST http://localhost:8080/api/v1/executions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "action_ref": "core.echo",
+    "parameters": {
+      "message": "API test",
+      "uppercase": true
+    }
+  }'
+
+# Check execution status
+curl http://localhost:8080/api/v1/executions/{execution_id}
+```
+
+### Test Sensor via Sensor Service
+
+```bash
+# Start sensor service (future)
+# cargo run --bin attune-sensor
+
+# Check events created
+curl http://localhost:8080/api/v1/events?limit=10
+```
+
+---
+
+## Troubleshooting
+
+### Action Not Executing
+
+```bash
+# Check file permissions
+ls -la packs/core/actions/
+
+# Ensure scripts are executable
+chmod +x packs/core/actions/*.sh
+chmod +x packs/core/actions/*.py
+```
+
+### Python Import Errors
+
+```bash
+# Install required packages
+pip install requests>=2.28.0
+
+# Verify Python version
+python3 --version  # Should be 3.8+
+```
+
+### Environment Variables Not Working
+
+```bash
+# Print all ATTUNE_* environment variables
+env | grep ATTUNE_
+
+# Test with explicit export
+export ATTUNE_ACTION_MESSAGE="test"
+echo $ATTUNE_ACTION_MESSAGE
+```
+
+---
+
+## Automated Test Script
+
+Create a test script `test_core_pack.sh`:
+
+```bash
+#!/bin/bash
+set -e
+
+echo "Testing Core Pack Actions..."
+
+# Test echo
+echo "→ Testing core.echo..."
+export ATTUNE_ACTION_MESSAGE="Test"
+./packs/core/actions/echo.sh > /dev/null
+echo "✓ core.echo passed"
+
+# Test sleep
+echo "→ Testing core.sleep..."
+export ATTUNE_ACTION_SECONDS=1
+./packs/core/actions/sleep.sh > /dev/null
+echo "✓ core.sleep passed"
+
+# Test noop
+echo "→ Testing core.noop..."
+export ATTUNE_ACTION_MESSAGE="test"
+./packs/core/actions/noop.sh > /dev/null
+echo "✓ core.noop passed"
+
+# Test HTTP request
+echo "→ Testing core.http_request..."
+export ATTUNE_ACTION_URL="https://httpbin.org/get"
+export ATTUNE_ACTION_METHOD="GET"
+python3 ./packs/core/actions/http_request.py > /dev/null
+echo "✓ core.http_request passed"
+
+echo ""
+echo "All tests passed! ✓"
+```
+
+Run with:
+```bash
+chmod +x test_core_pack.sh
+./test_core_pack.sh
+```
+
+---
+
+## Next Steps
+
+1. Implement pack loader to register components in database
+2. Update worker service to execute actions from filesystem
+3. Update sensor service to run sensors from filesystem
+4. Add comprehensive integration tests
+5. Create CLI commands for pack management
+

+# Core Pack Actions
+
+## Overview
+
+All actions in the core pack are implemented as **pure POSIX shell scripts** with **zero external dependencies** (except `curl` for HTTP actions). This design ensures maximum portability and minimal runtime requirements.
+
+**Key Principles:**
+- **POSIX shell only** - No bash-specific features, works everywhere
+- **DOTENV parameter format** - Simple key=value format, no JSON parsing needed
+- **No jq/yq/Python/Node.js** - Core pack depends only on standard POSIX utilities
+- **Stdin parameter delivery** - Secure, never exposed in process list
+- **Explicit output formats** - text, json, or yaml
+
+## Parameter Delivery Method
+
+**All actions use stdin with DOTENV format:**
+- Parameters read from **stdin** in `key=value` format
+- Use `parameter_delivery: stdin` and `parameter_format: dotenv` in YAML
+- Stdin is closed after delivery; scripts read until EOF
+- **DO NOT** use environment variables for parameters
+
+**Example DOTENV input:**
+```
+message="Hello World"
+seconds=5
+enabled=true
+```
+
+## Output Format
+
+**All actions must specify an `output_format`:**
+- `text` - Plain text output (stored as-is, no parsing)
+- `json` - JSON structured data (parsed into JSONB field)
+- `yaml` - YAML structured data (parsed into JSONB field)
+
+**Output schema:**
+- Only applicable for `json` and `yaml` formats
+- Describes the structure of data written to stdout
+- **Should NOT include** stdout/stderr/exit_code (captured automatically)
+
+## Environment Variables
+
+### Standard Environment Variables (Provided by Worker)
+
+The worker automatically provides these environment variables to all action executions:
+
+| Variable | Description | Always Present |
+|----------|-------------|----------------|
+| `ATTUNE_ACTION` | Action ref (e.g., `core.http_request`) | ✅ Yes |
+| `ATTUNE_EXEC_ID` | Execution database ID | ✅ Yes |
+| `ATTUNE_API_TOKEN` | Execution-scoped API token | ✅ Yes |
+| `ATTUNE_RULE` | Rule ref that triggered execution | ❌ Only if from rule |
+| `ATTUNE_TRIGGER` | Trigger ref that caused enforcement | ❌ Only if from trigger |
+
+**Use cases:**
+- Logging with execution context
+- Calling Attune API (using `ATTUNE_API_TOKEN`)
+- Conditional logic based on rule/trigger
+- Creating child executions
+- Accessing secrets via API
+
+### Custom Environment Variables (Optional)
+
+Custom environment variables can be set via `execution.env_vars` field for:
+- **Debug/logging controls** (e.g., `DEBUG=1`, `LOG_LEVEL=debug`)
+- **Runtime configuration** (e.g., custom paths, feature flags)
+
+Environment variables should **NEVER** be used for:
+- Action parameters (use stdin DOTENV instead)
+- Secrets or credentials (use `ATTUNE_API_TOKEN` to fetch from key vault)
+- User-provided data (use stdin parameters)
+
+## Implementation Pattern
+
+### POSIX Shell Actions (Standard Pattern)
+
+All core pack actions follow this pattern:
+
+```sh
+#!/bin/sh
+# Action Name - Core Pack
+# Brief description
+#
+# This script uses pure POSIX shell without external dependencies like jq.
+# It reads parameters in DOTENV format from stdin until EOF.
+
+set -e
+
+# Initialize variables with defaults
+param1=""
+param2="default_value"
+
+# Read DOTENV-formatted parameters from stdin until EOF
+while IFS= read -r line; do
+    [ -z "$line" ] && continue
+
+    key="${line%%=*}"
+    value="${line#*=}"
+
+    # Remove quotes if present
+    case "$value" in
+        \"*\") value="${value#\"}"; value="${value%\"}" ;;
+        \'*\') value="${value#\'}"; value="${value%\'}" ;;
+    esac
+
+    # Process parameters
+    case "$key" in
+        param1) param1="$value" ;;
+        param2) param2="$value" ;;
+    esac
+done
+
+# Validate required parameters
+if [ -z "$param1" ]; then
+    echo "ERROR: param1 is required" >&2
+    exit 1
+fi
+
+# Action logic
+echo "Processing: $param1"
+
+exit 0
+```
+
+### Boolean Normalization
+
+```sh
+case "$bool_param" in
+    true|True|TRUE|yes|Yes|YES|1) bool_param="true" ;;
+    *) bool_param="false" ;;
+esac
+```
+
+### Numeric Validation
+
+```sh
+case "$number" in
+    ''|*[!0-9]*)
+        echo "ERROR: must be a number" >&2
+        exit 1
+        ;;
+esac
+```
+
+## Core Pack Actions
+
+### Simple Actions
+
+1. **echo.sh** - Outputs a message (reference implementation)
+2. **sleep.sh** - Pauses execution for a specified duration
+3. **noop.sh** - Does nothing (useful for testing and placeholder workflows)
+
+### HTTP Action
+
+4. **http_request.sh** - Makes HTTP requests with full feature support:
+   - Multiple HTTP methods (GET, POST, PUT, PATCH, DELETE, etc.)
+   - Custom headers and query parameters
+   - Authentication (basic, bearer token)
+   - SSL verification control
+   - Redirect following
+   - JSON output with parsed response
+
+### Pack Management Actions (API Wrappers)
+
+These actions wrap Attune API endpoints for pack management:
+
+5. **download_packs.sh** - Downloads packs from git/HTTP/registry
+6. **build_pack_envs.sh** - Builds runtime environments for packs
+7. **register_packs.sh** - Registers packs in the database
+8. **get_pack_dependencies.sh** - Analyzes pack dependencies
+
+All API wrappers:
+- Accept parameters via DOTENV format
+- Build JSON request bodies manually (no jq)
+- Make authenticated API calls with curl
+- Extract response data using simple sed patterns
+- Return structured JSON output
+
+## Testing Actions Locally
+
+Test actions by echoing DOTENV format to stdin:
+
+```bash
+# Test echo action
+printf 'message="Hello World"\n' | ./echo.sh
+
+# Test with empty parameters
+printf '' | ./echo.sh
+
+# Test sleep action
+printf 'seconds=2\nmessage="Sleeping..."\n' | ./sleep.sh
+
+# Test http_request action
+printf 'url="https://api.github.com"\nmethod="GET"\n' | ./http_request.sh
+
+# Test with file input
+cat params.dotenv | ./echo.sh
+```
+
+## YAML Configuration Example
+
+```yaml
+ref: core.example_action
+label: "Example Action"
+description: "Example action demonstrating DOTENV format"
+enabled: true
+runner_type: shell
+entry_point: example.sh
+
+# IMPORTANT: Use DOTENV format for POSIX shell compatibility
+parameter_delivery: stdin
+parameter_format: dotenv
+
+# Output format: text, json, or yaml
+output_format: text
+
+parameters:
+  type: object
+  properties:
+    message:
+      type: string
+      description: "Message to output"
+      default: ""
+    count:
+      type: integer
+      description: "Number of times to repeat"
+      default: 1
+  required:
+    - message
+```
+
+## Dependencies
+
+**Core pack has ZERO runtime dependencies:**
+
+✅ **Required (universally available):**
+- POSIX-compliant shell (`/bin/sh`)
+- `curl` (for HTTP actions only)
+- Standard POSIX utilities: `sed`, `mktemp`, `cat`, `printf`, `sleep`
+
+❌ **NOT Required:**
+- `jq` - Eliminated (was used for JSON parsing)
+- `yq` - Never used
+- Python - Not used in core pack actions
+- Node.js - Not used in core pack actions
+- bash - Scripts are POSIX-compliant
+- Any other external tools or libraries
+
+This makes the core pack **maximally portable** and suitable for minimal containers (Alpine, distroless, etc.).
+
+## Security Benefits
+
+1. **No process exposure** - Parameters never appear in `ps`, `/proc/<pid>/environ`
+2. **Secure by default** - All actions use stdin, no special configuration needed
+3. **Clear separation** - Action parameters vs. environment configuration
+4. **Audit friendly** - All sensitive data flows through stdin, not environment
+5. **Minimal attack surface** - No external dependencies to exploit
+
+## Best Practices
+
+### Parameters
+1. **Always use stdin with DOTENV format** for action parameters
+2. **Handle quoted values** - Remove both single and double quotes
+3. **Provide sensible defaults** - Use empty string, 0, false as appropriate
+4. **Validate required params** - Exit with error if truly required parameters missing
+5. **Mark secrets** - Use `secret: true` in YAML for sensitive parameters
+6. **Never use env vars for parameters** - Parameters come from stdin only
+
+### Environment Variables
+1. **Use standard ATTUNE_* variables** - Worker provides execution context
+2. **Access API with ATTUNE_API_TOKEN** - Execution-scoped authentication
+3. **Log with context** - Include `ATTUNE_ACTION` and `ATTUNE_EXEC_ID` in logs
+4. **Never log ATTUNE_API_TOKEN** - Security sensitive
+5. **Use env vars for runtime config only** - Not for user data or parameters
+
+### Output Format
+1. **Specify output_format** - Always set to "text", "json", or "yaml"
+2. **Use text for simple output** - Messages, logs, unstructured data
+3. **Use json for structured data** - API responses, complex results
+4. **Define schema for structured output** - Only for json/yaml formats
+5. **Use stderr for diagnostics** - Error messages go to stderr, not stdout
+6. **Return proper exit codes** - 0 for success, non-zero for failure
+
+### Shell Script Best Practices
+1. **Use `#!/bin/sh`** - POSIX shell, not bash
+2. **Use `set -e`** - Exit on error
+3. **Quote all variables** - `"$var"` not `$var`
+4. **Use `case` not `if`** - More portable for pattern matching
+5. **Clean up temp files** - Use trap handlers
+6. **Avoid bash-isms** - No `[[`, `${var^^}`, `=~`, arrays, etc.
+
+## Execution Metadata (Automatic)
+
+The following are **automatically captured** by the worker and should **NOT** be included in output schemas:
+
+- `stdout` - Raw standard output (captured as-is)
+- `stderr` - Standard error output (written to log file)
+- `exit_code` - Process exit code (0 = success)
+- `duration_ms` - Execution duration in milliseconds
+
+These are execution system concerns, not action output concerns.
+
+## Example: Complete Action
+
+```sh
+#!/bin/sh
+# Example Action - Core Pack
+# Demonstrates DOTENV parameter parsing and environment variable usage
+#
+# This script uses pure POSIX shell without external dependencies like jq.
+
+set -e
+
+# Log execution start
+echo "[$ATTUNE_ACTION] [Exec: $ATTUNE_EXEC_ID] Starting" >&2
+
+# Initialize variables
+url=""
+timeout="30"
+
+# Read DOTENV parameters from stdin until EOF
+while IFS= read -r line; do
+    [ -z "$line" ] && continue
+
+    key="${line%%=*}"
+    value="${line#*=}"
+    
+    case "$value" in
+        \"*\") value="${value#\"}"; value="${value%\"}" ;;
+    esac
+
+    case "$key" in
+        url) url="$value" ;;
+        timeout) timeout="$value" ;;
+    esac
+done
+
+# Validate
+if [ -z "$url" ]; then
+    echo "ERROR: url is required" >&2
+    exit 1
+fi
+
+# Execute
+echo "Fetching: $url" >&2
+result=$(curl -s --max-time "$timeout" "$url")
+
+# Output
+echo "$result"
+
+echo "[$ATTUNE_ACTION] [Exec: $ATTUNE_EXEC_ID] Completed" >&2
+exit 0
+```

+# Core Pack Runtime Metadata
+
+This directory contains runtime metadata YAML files for the core pack. Each file defines a runtime environment that can be used to execute actions and sensors.
+
+## File Structure
+
+Each runtime YAML file contains only the fields that are stored in the database:
+
+- `ref` - Unique runtime reference (format: pack.name)
+- `pack_ref` - Pack this runtime belongs to
+- `name` - Human-readable runtime name
+- `description` - Brief description of the runtime
+- `distributions` - Runtime verification and capability metadata (JSONB)
+- `installation` - Installation requirements and metadata (JSONB)
+- `execution_config` - Interpreter, environment, dependency, and execution-time env var metadata
+
+## `execution_config.env_vars`
+
+Runtime authors can declare execution-time environment variables in a purely declarative way.
+
+String values replace the variable entirely:
+
+```yaml
+env_vars:
+  NODE_PATH: "{env_dir}/node_modules"
+```
+
+Object values support merge semantics against an existing value already present in the execution environment:
+
+```yaml
+env_vars:
+  PYTHONPATH:
+    operation: prepend
+    value: "{pack_dir}/lib"
+    separator: ":"
+```
+
+Supported operations:
+
+- `set` - Replace the variable with the resolved value
+- `prepend` - Add the resolved value before the existing value
+- `append` - Add the resolved value after the existing value
+
+Supported template variables:
+
+- `{pack_dir}`
+- `{env_dir}`
+- `{interpreter}`
+- `{manifest_path}`
+
+## Available Runtimes
+
+- **python.yaml** - Python 3 runtime for actions and sensors
+- **nodejs.yaml** - Node.js runtime for JavaScript-based actions and sensors
+- **shell.yaml** - Shell (bash/sh) runtime - always available
+- **native.yaml** - Native compiled runtime (Rust, Go, C, etc.) - executes binaries directly without an interpreter
+
+## Loading
+
+Runtime metadata files are loaded by the pack loading system and inserted into the `runtime` table in the database.

+    The timer sensor is a built-in system sensor that monitors all timer-based
+    triggers and fires events according to their schedules. It supports three
+    timer types:
+
+    1. Interval timers: Fire at regular intervals (seconds, minutes, hours, days)
+    2. Cron timers: Fire based on cron schedule expressions (e.g., "0 0 * * * *")
+    3. DateTime timers: Fire once at a specific date and time (one-shot)
+
+    This sensor uses tokio-cron-scheduler for efficient async scheduling and
+    runs continuously as part of the Attune sensor service.

+# Core Pack Unit Tests
+
+This directory contains comprehensive unit tests for the Attune Core Pack actions.
+
+> **Note**: These tests can be run manually (as documented below) or programmatically during pack installation via the Pack Testing Framework. See [`docs/pack-testing-framework.md`](../../../docs/pack-testing-framework.md) for details on automatic test execution during pack installation.

+Failed:       0
+
+✓ All tests passed!
+```
+
+## Adding New Tests
+
+### Adding to Bash Test Runner
+
+Edit `run_tests.sh` and add new test cases:
+
+```bash
+# Test new action
+echo -e "${BLUE}Testing core.my_action${NC}"
+
+check_output \
+    "my_action: basic test" \
+    "cd '$ACTIONS_DIR' && ATTUNE_ACTION_PARAM='value' ./my_action.sh" \
+    "Expected output"
+
+run_test_expect_fail \
+    "my_action: invalid input" \
+    "cd '$ACTIONS_DIR' && ATTUNE_ACTION_PARAM='invalid' ./my_action.sh"
+```
+
+### Adding to Python Test Suite
+
+Add a new test class to `test_actions.py`:
+
+```python
+class TestMyAction(CorePackTestCase):
+    """Tests for core.my_action"""
+
+    def test_basic_functionality(self):
+        """Test basic functionality"""
+        stdout, stderr, code = self.run_action(
+            "my_action.sh",
+            {"ATTUNE_ACTION_PARAM": "value"}
+        )
+        self.assertEqual(code, 0)
+        self.assertIn("expected output", stdout)
+
+    def test_error_handling(self):
+        """Test error handling"""
+        stdout, stderr, code = self.run_action(
+            "my_action.sh",
+            {"ATTUNE_ACTION_PARAM": "invalid"},
+            expect_failure=True
+        )
+        self.assertNotEqual(code, 0)
+        self.assertIn("ERROR", stderr)
+```
+
+## Continuous Integration
+
+### GitHub Actions Example
+
+```yaml
+name: Core Pack Tests
+
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - uses: actions/setup-python@v4
+        with:
+          python-version: '3.10'
+      
+      - name: Install dependencies
+        run: pip install pytest pyyaml requests
+      
+      - name: Run bash tests
+        run: |
+          cd packs/core/tests
+          chmod +x run_tests.sh
+          ./run_tests.sh
+      
+      - name: Run python tests
+        run: |
+          cd packs/core/tests
+          pytest test_actions.py -v
+```
+
+## Troubleshooting
+
+### Tests fail with "Permission denied"
+
+```bash
+chmod +x packs/core/actions/*.sh
+chmod +x packs/core/actions/*.py
+```
+
+### Python import errors
+
+```bash
+# Install required libraries
+pip install requests>=2.28.0 pyyaml
+```
+
+### HTTP tests timing out
+
+The `httpbin.org` service may be slow or unavailable. Try:
+- Increasing timeout in tests
+- Running tests again later
+- Using a local httpbin instance
+
+### YAML validation fails
+
+Ensure PyYAML is installed:
+```bash
+pip install pyyaml
+```
+
+## Best Practices
+
+1. **Test both success and failure cases** - Don't just test the happy path
+2. **Use descriptive test names** - Make it clear what each test validates
+3. **Test edge cases** - Empty strings, zero values, boundary conditions
+4. **Validate error messages** - Ensure helpful errors are returned
+5. **Keep tests fast** - Use minimal sleep times, short timeouts
+6. **Make tests independent** - Each test should work in isolation
+7. **Document expected behavior** - Add comments for complex tests
+
+## Performance
+
+Expected test execution times:
+
+- **Bash runner**: ~15-30 seconds (with HTTP tests)
+- **Python suite**: ~20-40 seconds (with HTTP tests)
+- **Without HTTP tests**: ~5-10 seconds
+
+Slowest tests:
+- `core.sleep` timing validation tests (intentional delays)
+- `core.http_request` network requests
+
+## Future Improvements
+
+- [ ] Add integration tests with Attune services
+- [ ] Add performance benchmarks
+- [ ] Test concurrent action execution
+- [ ] Mock HTTP requests for faster tests
+- [ ] Add property-based testing (hypothesis)
+- [ ] Test sensor functionality
+- [ ] Test trigger functionality
+- [ ] Add coverage reporting
+
+## Programmatic Test Execution
+
+The Core Pack includes a `testing` section in `pack.yaml` that enables automatic test execution during pack installation:
+
+```yaml
+testing:
+  enabled: true
+  runners:
+    shell:
+      entry_point: "tests/run_tests.sh"
+      timeout: 60
+    python:
+      entry_point: "tests/test_actions.py"
+      timeout: 120
+  min_pass_rate: 1.0
+  on_failure: "block"
+```
+
+When installing the pack with `attune pack install`, these tests will run automatically to verify the pack works in the target environment.

+
+## Test Execution
+
+### Bash Test Runner
+```bash
+cd packs/core/tests
+./run_tests.sh
+```
+
+**Results:**
+```
+Total Tests:  36
+Passed:       36
+Failed:       0
+
+✓ All tests passed!
+```
+
+**Execution Time**: ~15-30 seconds (including HTTP tests)
+
+### Python Test Suite
+```bash
+cd packs/core/tests
+python3 test_actions.py
+```
+
+**Results:**
+```
+Ran 38 tests in 11.797s
+OK (skipped=2)
+```
+
+**Execution Time**: ~12 seconds
+
+---
+
+## Test Features
+
+### Error Handling Coverage
+✅ Missing required parameters  
+✅ Invalid parameter types  
+✅ Out-of-range values  
+✅ Negative values where inappropriate  
+✅ Non-numeric values for numeric parameters  
+✅ Empty values  
+✅ Network timeouts  
+✅ HTTP error responses  
+
+### Positive Test Coverage
+✅ Default parameter values  
+✅ Minimum/maximum valid values  
+✅ Various parameter combinations  
+✅ Success paths  
+✅ Output validation  
+✅ Exit code verification  
+✅ Timing validation (for sleep action)  
+
+### Integration Tests
+✅ Network requests (HTTP action)  
+✅ File system operations  
+✅ Environment variable parsing  
+✅ Script execution  
+
+---
+
+## Fixed Issues
+
+### Issue 1: SECONDS Variable Conflict
+**Problem**: The `sleep.sh` script used `SECONDS` as a variable name, which conflicts with bash's built-in `SECONDS` variable that tracks shell uptime.
+
+**Solution**: Renamed the variable to `SLEEP_SECONDS` to avoid the conflict.
+
+**Files Modified**: `packs/core/actions/sleep.sh`
+
+---
+
+## Test Infrastructure
+
+### Test Files
+- `run_tests.sh` - Bash-based test runner (36 tests)
+- `test_actions.py` - Python unittest suite (38 tests)
+- `README.md` - Testing documentation
+- `TEST_RESULTS.md` - This file
+
+### Dependencies
+**Required:**
+- bash
+- python3
+
+**Optional:**
+- `pytest` - Better test output
+- `PyYAML` - YAML validation
+- `requests` - HTTP action tests
+
+### CI/CD Ready
+Both test suites are designed for continuous integration:
+- Non-zero exit codes on failure
+- Clear pass/fail reporting
+- Color-coded output (bash runner)
+- Structured test results (Python suite)
+- Optional dependency handling
+
+---
+
+## Test Maintenance
+
+### Adding New Tests
+1. Add test cases to `run_tests.sh` for quick validation
+2. Add test methods to `test_actions.py` for comprehensive coverage
+3. Update this document with new test counts
+4. Run both test suites to verify
+
+### When to Run Tests
+- ✅ Before committing changes to actions
+- ✅ After modifying action scripts
+- ✅ Before releasing new pack versions
+- ✅ In CI/CD pipelines
+- ✅ When troubleshooting action behavior
+
+---
+
+## Known Limitations
+
+1. **HTTP Tests**: Depend on external service (httpbin.org)
+   - May fail if service is down
+   - May be slow depending on network
+   - Could be replaced with local mock server
+
+2. **Timing Tests**: Sleep action timing tests have tolerance
+   - Allow for system scheduling delays
+   - May be slower on heavily loaded systems
+
+3. **Optional Dependencies**: Some tests skipped if:
+   - PyYAML not installed (YAML validation)
+   - requests not installed (HTTP tests)
+
+---
+
+## Future Enhancements
+
+- [ ] Add sensor unit tests
+- [ ] Add trigger unit tests  
+- [ ] Mock HTTP requests for faster tests
+- [ ] Add performance benchmarks
+- [ ] Add concurrent execution tests
+- [ ] Add code coverage reporting
+- [ ] Add property-based testing (hypothesis)
+- [ ] Integration tests with Attune services
+
+---
+
+## Conclusion
+
+✅ **All core pack actions are thoroughly tested and working correctly.**
+
+The test suite provides:
+- Comprehensive coverage of success and failure cases
+- Fast execution for rapid development feedback
+- Clear documentation of expected behavior
+- Confidence in core pack reliability
+
+Both bash and Python test runners are available for different use cases:
+- **Bash runner**: Quick, minimal dependencies, great for local development
+- **Python suite**: Structured, detailed, perfect for CI/CD and debugging

+# Pack Installation Workflow System
+
+**Status**: Schema Complete, Implementation Required  
+**Version**: 1.0.0  
+**Last Updated**: 2025-02-05
+
+---
+
+## Overview
+
+The pack installation workflow provides a comprehensive, automated system for installing Attune packs from multiple sources with automatic dependency resolution, runtime environment setup, testing, and registration.
+
+This document describes the workflow architecture, supporting actions, and implementation requirements.
+
+---
+
+## Architecture
+
+### Main Workflow: `core.install_packs`
+
+A multi-stage orchestration workflow that handles the complete pack installation lifecycle:
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│                    Install Packs Workflow                    │

+│  1. Initialize           → Set up temp directory             │
+│  2. Download Packs       → Fetch from git/HTTP/registry     │
+│  3. Check Results        → Validate downloads                │
+│  4. Get Dependencies     → Parse pack.yaml                   │
+│  5. Install Dependencies → Recursive installation            │
+│  6. Build Environments   → Python/Node.js setup              │
+│  7. Run Tests           → Verify functionality               │
+│  8. Register Packs      → Load into database                 │
+│  9. Cleanup             → Remove temp files                  │
+│                                                               │
+└─────────────────────────────────────────────────────────────┘
+```
+
+### Supporting Actions
+
+The workflow delegates specific tasks to five core actions:
+
+1. **`core.download_packs`** - Download from multiple sources
+2. **`core.get_pack_dependencies`** - Parse dependency information
+3. **`core.build_pack_envs`** - Create runtime environments
+4. **`core.run_pack_tests`** - Execute test suites
+5. **`core.register_packs`** - Load components into database
+

+
+---
+
+## Action Specifications
+
+### 1. Download Packs (`core.download_packs`)
+
+**Purpose**: Download packs from various sources to a temporary directory.
+
+**Responsibilities:**
+- Detect source type (git/HTTP/registry)
+- Clone git repositories with optional ref checkout
+- Download and extract HTTP archives
+- Resolve pack registry references to download URLs
+- Locate and parse `pack.yaml` files
+- Calculate directory checksums
+- Return download metadata for downstream tasks
+
+**Input:**
+```yaml
+packs: ["https://github.com/attune/pack-slack.git"]
+destination_dir: "/tmp/attune-pack-install-abc123"
+registry_url: "https://registry.attune.io/index.json"
+ref_spec: "v1.0.0"
+timeout: 300
+verify_ssl: true
+api_url: "http://localhost:8080"
+```
+
+**Output:**
+```json
+{
+  "downloaded_packs": [
+    {
+      "source": "https://github.com/attune/pack-slack.git",
+      "source_type": "git",
+      "pack_path": "/tmp/attune-pack-install-abc123/slack",
+      "pack_ref": "slack",
+      "pack_version": "1.0.0",
+      "git_commit": "a1b2c3d4e5",
+      "checksum": "sha256:..."
+    }
+  ],
+  "failed_packs": [],
+  "total_count": 1,
+  "success_count": 1,
+  "failure_count": 0
+}
+```
+
+**Implementation Notes:**
+- Should call API endpoint or implement git/HTTP logic directly
+- Must handle authentication (SSH keys for git, API tokens)
+- Must validate `pack.yaml` exists and is readable
+- Should support both root-level and `pack/` subdirectory structures
+
+---
+
+### 2. Get Pack Dependencies (`core.get_pack_dependencies`)
+
+**Purpose**: Parse `pack.yaml` files to identify pack and runtime dependencies.
+
+**Responsibilities:**
+- Read and parse `pack.yaml` files (YAML parsing)
+- Extract `dependencies` section (pack dependencies)
+- Extract `python` and `nodejs` runtime requirements
+- Check which pack dependencies are already installed
+- Identify `requirements.txt` and `package.json` files
+- Build list of missing dependencies for installation
+
+**Input:**
+```yaml
+pack_paths: ["/tmp/attune-pack-install-abc123/slack"]
+api_url: "http://localhost:8080"
+skip_validation: false
+```
+
+**Output:**
+```json
+{
+  "dependencies": [
+    {
+      "pack_ref": "core",
+      "version_spec": ">=1.0.0",
+      "required_by": "slack",
+      "already_installed": true
+    }
+  ],
+  "runtime_requirements": {
+    "slack": {
+      "pack_ref": "slack",
+      "python": {
+        "version": ">=3.8",
+        "requirements_file": "/tmp/.../slack/requirements.txt"
+      }
+    }
+  },
+  "missing_dependencies": [
+    {
+      "pack_ref": "http",
+      "version_spec": "^1.0.0",
+      "required_by": "slack"
+    }
+  ],
+  "analyzed_packs": [
+    {
+      "pack_ref": "slack",
+      "pack_path": "/tmp/.../slack",
+      "has_dependencies": true,
+      "dependency_count": 2
+    }
+  ],
+  "errors": []
+}
+```
+
+**Implementation Notes:**
+- Must parse YAML files (use `yq`, Python, or API call)
+- Should call `GET /api/v1/packs` to check installed packs
+- Must handle missing or malformed `pack.yaml` files gracefully
+- Should validate version specifications (semver)
+
+---
+
+### 3. Build Pack Environments (`core.build_pack_envs`)
+
+**Purpose**: Create runtime environments and install dependencies.
+
+**Responsibilities:**
+- Create Python virtualenvs for packs with Python dependencies
+- Install packages from `requirements.txt` using pip
+- Run `npm install` for packs with Node.js dependencies
+- Handle environment creation failures gracefully
+- Track installed package counts and build times
+- Support force rebuild of existing environments
+
+**Input:**
+```yaml
+pack_paths: ["/tmp/attune-pack-install-abc123/slack"]
+packs_base_dir: "/opt/attune/packs"
+python_version: "3.11"
+nodejs_version: "20"
+skip_python: false
+skip_nodejs: false
+force_rebuild: false
+timeout: 600
+```
+
+**Output:**
+```json
+{
+  "built_environments": [
+    {
+      "pack_ref": "slack",
+      "pack_path": "/tmp/.../slack",
+      "environments": {
+        "python": {
+          "virtualenv_path": "/tmp/.../slack/virtualenv",
+          "requirements_installed": true,
+          "package_count": 15,
+          "python_version": "3.11.2"
+        }
+      },
+      "duration_ms": 45000
+    }
+  ],
+  "failed_environments": [],
+  "summary": {
+    "total_packs": 1,
+    "success_count": 1,
+    "failure_count": 0,
+    "python_envs_built": 1,
+    "nodejs_envs_built": 0,
+    "total_duration_ms": 45000
+  }
+}
+```
+
+**Implementation Notes:**
+- Python virtualenv creation: `python -m venv {pack_path}/virtualenv`
+- Pip install: `source virtualenv/bin/activate && pip install -r requirements.txt`
+- Node.js install: `npm install --production` in pack directory
+- Must handle timeouts and cleanup on failure
+- Should use containerized workers for isolation
+
+---
+
+### 4. Run Pack Tests (`core.run_pack_tests`)
+
+**Purpose**: Execute pack test suites to verify functionality.
+
+**Responsibilities:**
+- Detect test framework (pytest, unittest, npm test, shell scripts)
+- Execute tests in isolated environment
+- Capture test output and results
+- Return pass/fail status with details
+- Support parallel test execution
+- Handle test timeouts
+
+**Input:**
+```yaml
+pack_paths: ["/tmp/attune-pack-install-abc123/slack"]
+timeout: 300
+fail_on_error: false
+```
+
+**Output:**
+```json
+{
+  "test_results": [
+    {
+      "pack_ref": "slack",
+      "status": "passed",
+      "total_tests": 25,
+      "passed": 25,
+      "failed": 0,
+      "skipped": 0,
+      "duration_ms": 12000,
+      "output": "..."
+    }
+  ],
+  "summary": {
+    "total_packs": 1,
+    "all_passed": true,
+    "total_tests": 25,
+    "total_passed": 25,
+    "total_failed": 0
+  }
+}
+```
+
+**Implementation Notes:**
+- Check for `test` section in `pack.yaml`
+- Default test discovery: `tests/` directory
+- Python: Run pytest or unittest
+- Node.js: Run `npm test`
+- Shell: Execute `test.sh` scripts
+- Should capture stdout/stderr for debugging
+
+---
+
+### 5. Register Packs (`core.register_packs`)
+
+**Purpose**: Validate schemas, load components into database, copy to storage.
+
+**Responsibilities:**
+- Validate `pack.yaml` schema
+- Scan for component files (actions, sensors, triggers, rules, workflows, policies)
+- Validate each component schema
+- Call API endpoint to register pack in database
+- Copy pack files to permanent storage (`/opt/attune/packs/{pack_ref}/`)
+- Record installation metadata
+- Handle registration rollback on failure (atomic operation)
+
+**Input:**
+```yaml
+pack_paths: ["/tmp/attune-pack-install-abc123/slack"]
+packs_base_dir: "/opt/attune/packs"
+skip_validation: false
+skip_tests: false
+force: false
+api_url: "http://localhost:8080"
+api_token: "jwt_token_here"
+```
+
+**Output:**
+```json
+{
+  "registered_packs": [
+    {
+      "pack_ref": "slack",
+      "pack_id": 42,
+      "pack_version": "1.0.0",
+      "storage_path": "/opt/attune/packs/slack",
+      "components_registered": {
+        "actions": 15,
+        "sensors": 3,
+        "triggers": 2,
+        "rules": 5,
+        "workflows": 2,
+        "policies": 0
+      },
+      "test_result": {
+        "status": "passed",
+        "total_tests": 25,
+        "passed": 25,
+        "failed": 0
+      },
+      "validation_results": {
+        "valid": true,
+        "errors": []
+      }
+    }
+  ],
+  "failed_packs": [],
+  "summary": {
+    "total_packs": 1,
+    "success_count": 1,
+    "failure_count": 0,
+    "total_components": 27,
+    "duration_ms": 8000
+  }
+}
+```
+
+**Implementation Notes:**
+- **Primary approach**: Call `POST /api/v1/packs/register` endpoint
+- The API already implements:
+  - Pack metadata validation
+  - Component scanning and registration
+  - Database record creation
+  - File copying to permanent storage
+  - Installation metadata tracking
+- This action should be a thin wrapper for API calls
+- Must handle authentication (JWT token)
+- Must implement proper error handling and retries
+- Should validate API response and extract relevant data
+
+**API Endpoint Reference:**
+```
+POST /api/v1/packs/register
+Content-Type: application/json
+Authorization: Bearer {token}
+
+{
+  "path": "/tmp/attune-pack-install-abc123/slack",
+  "force": false,
+  "skip_tests": false
+}
+
+Response:
+{
+  "data": {
+    "pack_id": 42,
+    "pack": { ... },
+    "test_result": { ... }
+  }
+}
+```
+
+---
+
+## Workflow Execution Flow
+
+### Success Path
+
+```
+1. Initialize
+   ↓
+2. Download Packs
+   ↓ (if any downloads succeeded)
+3. Check Results
+   ↓ (if not skip_dependencies)
+4. Get Dependencies
+   ↓ (if missing dependencies found)
+5. Install Dependencies (recursive call)
+   ↓
+6. Build Environments
+   ↓ (if not skip_tests)
+7. Run Tests
+   ↓
+8. Register Packs
+   ↓
+9. Cleanup Success
+   ✓ Complete
+```
+
+### Failure Handling
+
+Each stage can fail and trigger cleanup:
+
+- **Download fails**: Go to cleanup_on_failure
+- **Dependency installation fails**: 
+  - If `force=true`: Continue to build_environments
+  - If `force=false`: Go to cleanup_on_failure
+- **Environment build fails**:
+  - If `force=true` or `skip_env_build=true`: Continue
+  - If `force=false`: Go to cleanup_on_failure
+- **Tests fail**:
+  - If `force=true`: Continue to register_packs
+  - If `force=false`: Go to cleanup_on_failure
+- **Registration fails**: Go to cleanup_on_failure
+
+### Force Mode Behavior
+
+When `force: true`:
+
+- ✓ Continue even if downloads fail
+- ✓ Skip dependency validation failures
+- ✓ Skip environment build failures
+- ✓ Skip test failures
+- ✓ Override existing pack installations
+
+**Use Cases:**
+- Development and testing
+- Emergency deployments
+- Pack upgrades
+- Recovery from partial installations
+
+**Warning:** Force mode bypasses safety checks. Use cautiously in production.
+
+---
+
+## Recursive Dependency Resolution
+
+The workflow supports recursive dependency installation:
+
+```
+install_packs(["slack"])
+  ↓
+  Depends on: ["core@>=1.0.0", "http@^1.0.0"]
+  ↓
+  install_packs(["http"])  # Recursive call
+    ↓
+    Depends on: ["core@>=1.0.0"]
+    ↓
+    core already installed ✓
+  ✓
+  http installed ✓
+  ↓
+slack installed ✓
+```
+
+**Features:**
+- Automatically detects and installs missing dependencies
+- Prevents circular dependencies (each pack registered once)
+- Respects version constraints (semver)
+- Installs dependencies depth-first
+- Tracks installed packs to avoid duplicates
+
+---
+
+## Error Handling
+
+### Atomic Registration
+
+Pack registration is atomic - all components are registered or none:
+
+- ✓ Validates all component schemas first
+- ✓ Creates database transaction for registration
+- ✓ Rolls back on any component failure
+- ✓ Prevents partial pack installations
+
+### Cleanup Strategy
+
+Temporary directories are always cleaned up:
+
+- **On success**: Remove temp directory after registration
+- **On failure**: Remove temp directory and report errors
+- **On timeout**: Cleanup triggered by workflow timeout handler
+
+### Error Reporting
+
+Comprehensive error information returned:
+
+```json
+{
+  "failed_packs": [
+    {
+      "pack_path": "/tmp/.../custom-pack",
+      "pack_ref": "custom",
+      "error": "Schema validation failed: action 'do_thing' missing required field 'runner_type'",
+      "error_stage": "validation"
+    }
+  ]
+}
+```
+
+Error stages:
+- `validation` - Schema validation failed
+- `testing` - Pack tests failed
+- `database_registration` - Database operation failed
+- `file_copy` - File system operation failed
+- `api_call` - API request failed
+
+---
+
+## Implementation Status
+
+### ✅ Complete
+
+- Workflow YAML schema (`install_packs.yaml`)
+- Action YAML schemas (5 actions)
+- Action placeholder scripts (.sh files)
+- Documentation
+- Error handling structure
+- Output schemas
+
+### 🔄 Requires Implementation
+
+All action scripts currently return placeholder responses. Each needs proper implementation:
+
+#### 1. `download_packs.sh`
+
+**Implementation Options:**
+
+**Option A: API-based** (Recommended)
+- Create API endpoint: `POST /api/v1/packs/download`
+- Action calls API with pack list
+- API handles git/HTTP/registry logic
+- Returns download results to action
+
+**Option B: Direct implementation**
+- Implement git cloning logic in script
+- Implement HTTP download and extraction
+- Implement registry lookup and resolution
+- Handle all error cases
+
+**Recommendation**: Option A (API-based) keeps action scripts lean and centralizes pack handling logic in the API service.
+
+#### 2. `get_pack_dependencies.sh`
+
+**Implementation approach:**
+- Parse YAML files (use `yq` tool or Python script)
+- Extract dependencies from `pack.yaml`
+- Call `GET /api/v1/packs` to get installed packs
+- Compare and build missing dependencies list
+
+#### 3. `build_pack_envs.sh`
+
+**Implementation approach:**
+- For each pack with `requirements.txt`:
+  ```bash
+  python -m venv {pack_path}/virtualenv
+  source {pack_path}/virtualenv/bin/activate
+  pip install -r {pack_path}/requirements.txt
+  ```
+- For each pack with `package.json`:
+  ```bash
+  cd {pack_path}
+  npm install --production
+  ```
+- Handle timeouts and errors
+- Use containerized workers for isolation
+
+#### 4. `run_pack_tests.sh`
+
+**Implementation approach:**
+- Already exists in core pack: `core.run_pack_tests`
+- May need minor updates for integration
+- Supports pytest, unittest, npm test
+
+#### 5. `register_packs.sh`
+
+**Implementation approach:**
+- Call existing API endpoint: `POST /api/v1/packs/register`
+- Send pack path and options
+- Parse API response
+- Handle authentication (JWT token from workflow context)
+
+**API Integration:**
+```bash
+curl -X POST "$API_URL/api/v1/packs/register" \
+  -H "Authorization: Bearer $API_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d "{
+    \"path\": \"$pack_path\",
+    \"force\": $FORCE,
+    \"skip_tests\": $SKIP_TESTS
+  }"
+```
+
+---
+
+## Testing Strategy
+
+### Unit Tests
+
+Test each action independently:
+
+```bash
+# Test download_packs with mock git repo
+./actions/download_packs.sh \
+  ATTUNE_ACTION_PACKS='["https://github.com/test/pack-test.git"]' \
+  ATTUNE_ACTION_DESTINATION_DIR=/tmp/test
+
+# Verify output structure
+jq '.downloaded_packs | length' output.json
+```
+
+### Integration Tests
+
+Test complete workflow:
+
+```bash
+# Execute workflow via API

+
+### End-to-End Tests
+
+Test with real packs:
+
+1. Install core pack (already installed)
+2. Install pack with dependencies
+3. Install pack from HTTP archive
+4. Install pack from registry reference
+5. Test force mode reinstallation
+6. Test error handling (invalid pack)
+
+---
+
+## Usage Examples
+
+### Example 1: Install Single Pack from Git
+
+```yaml
+workflow: core.install_packs
+input:
+  packs:
+    - "https://github.com/attune/pack-slack.git"
+  ref_spec: "v1.0.0"
+  skip_dependencies: false
+  skip_tests: false
+  force: false
+```
+
+### Example 2: Install Multiple Packs from Registry
+
+```yaml
+workflow: core.install_packs
+input:
+  packs:
+    - "slack@1.0.0"
+    - "aws@^2.1.0"
+    - "kubernetes@>=3.0.0"
+  skip_dependencies: false
+  skip_tests: false
+```
+
+### Example 3: Force Reinstall with Skip Tests
+
+```yaml
+workflow: core.install_packs
+input:
+  packs:
+    - "https://github.com/myorg/pack-custom.git"
+  ref_spec: "main"
+  skip_dependencies: true
+  skip_tests: true
+  force: true
+```
+
+### Example 4: Install from HTTP Archive
+
+```yaml
+workflow: core.install_packs
+input:
+  packs:
+    - "https://example.com/packs/custom-pack-1.0.0.tar.gz"
+  skip_dependencies: false
+  skip_tests: false
+```
+
+---

+    This workflow orchestrates the complete pack installation process:
+
+    1. Download Packs: Downloads packs from git repositories, HTTP archives, or pack registry
+    2. Get Dependencies: Analyzes pack.yaml files to identify dependencies
+    3. Install Dependencies: Recursively installs missing pack dependencies
+    4. Build Environments: Creates Python virtualenvs, installs requirements.txt and package.json deps
+    5. Run Tests: Executes pack test suites (if present and not skipped)
+    6. Register Packs: Loads pack components into database and copies to permanent storage
+
+    The workflow supports:
+    - Multiple pack sources (git URLs, HTTP archives, pack refs)
+    - Automatic dependency resolution (recursive)
+    - Runtime environment setup (Python, Node.js)
+    - Pack testing before registration
+    - Force mode to override validation failures
+    - Comprehensive error handling and cleanup
