# API Completion Plan: Implementing Suppressed Features **Date:** 2026-01-27 **Status:** Phase 1 & 3 Complete, Phase 2 In Progress **Context:** During zero-warnings cleanup, several API methods and features were marked with `#[allow(dead_code)]` because they represent planned but unimplemented functionality. This document outlines a plan to implement these features. ## Overview We identified 4 main categories of suppressed features: 1. **CLI Client REST operations** - Missing HTTP methods for full CRUD 2. **CLI Configuration management** - Incomplete config commands and profile support 3. **Token refresh mechanism** - Session management for long-running CLI usage 4. **Executor monitoring APIs** - Runtime inspection of policies and queues --- ## Priority 1: Token Refresh Mechanism (High Impact) ### Problem - Access tokens expire after 1 hour - Long-running CLI sessions require manual re-login - No automatic token refresh flow ### Suppressed Methods - `ApiClient::set_auth_token()` - Update token after refresh - `ApiClient::clear_auth_token()` - Clear on logout/refresh failure - `CliConfig::refresh_token()` - Get refresh token from config ### Implementation Plan #### 1.1: Add Token Refresh API Endpoint **File:** `attune/crates/api/src/routes/auth.rs` ```rust #[utoipa::path( post, path = "/auth/refresh", request_body = RefreshTokenRequest, responses( (status = 200, description = "Token refreshed", body = LoginResponse), (status = 401, description = "Invalid refresh token") ), tag = "auth" )] async fn refresh_token( State(state): State, Json(req): Json, ) -> Result>, ApiError> { // Validate refresh token // Generate new access token (and optionally new refresh token) // Return new tokens } ``` **Add DTO:** `attune/crates/api/src/dto/auth.rs` ```rust #[derive(Deserialize)] pub struct RefreshTokenRequest { pub refresh_token: String, } ``` #### 1.2: Implement Automatic Refresh in CLI Client **File:** `attune/crates/cli/src/client.rs` Add method: ```rust pub async fn refresh_auth_token(&mut self) -> Result<()> { // Get refresh token from config // Call /auth/refresh endpoint // Update auth_token with set_auth_token() // Update config file with new tokens } ``` Enhance `execute()` method: ```rust async fn execute(&self, req: RequestBuilder) -> Result { let response = req.send().await?; // If 401 and we have refresh token, try refresh once if response.status() == StatusCode::UNAUTHORIZED { if let Ok(Some(_)) = config.refresh_token() { self.refresh_auth_token().await?; // Retry original request with new token } } self.handle_response(response).await } ``` #### 1.3: Add Refresh Command (Optional) **File:** `attune/crates/cli/src/commands/auth.rs` ```rust AuthCommands::Refresh => { // Manually refresh token // Useful for testing or explicit refresh } ``` **Effort:** 4-6 hours **Dependencies:** None **Value:** High - significantly improves CLI UX --- ## Priority 2: Complete CRUD Operations (High Impact) ### Problem - CLI can only Create (POST) and Read (GET) resources - No Update (PUT/PATCH) or Delete (DELETE) commands - REST client API incomplete ### Suppressed Methods - `ApiClient::put()` - For update operations - `ApiClient::delete()` - For delete operations - `ApiClient::get_with_query()` - For filtering/search ### Implementation Plan #### 2.1: Resource Update Commands Add update subcommands to existing command modules: **Pack Updates** (`attune/crates/cli/src/commands/pack.rs`): ```rust PackCommands::Update { ref_name: String, #[arg(long)] name: Option, #[arg(long)] description: Option, #[arg(long)] version: Option, #[arg(long)] enabled: Option, } => { let update = UpdatePackRequest { name, description, version, enabled }; let pack = client.put(&format!("/packs/{}", ref_name), &update).await?; // Display updated pack } ``` **Action Updates** (`attune/crates/cli/src/commands/action.rs`): ```rust ActionCommands::Update { ref_name: String, #[arg(long)] name: Option, #[arg(long)] description: Option, #[arg(long)] enabled: Option, } => { // Similar pattern } ``` Repeat for: Rules, Triggers, Sensors, Workflows #### 2.2: Resource Delete Commands Add delete subcommands: ```rust PackCommands::Delete { ref_name: String, #[arg(long)] force: bool, // Skip confirmation } => { if !force { let confirm = dialoguer::Confirm::new() .with_prompt(&format!("Delete pack '{}'?", ref_name)) .interact()?; if !confirm { return Ok(()); } } client.delete::<()>(&format!("/packs/{}", ref_name)).await?; print_success(&format!("Pack '{}' deleted", ref_name)); } ``` #### 2.3: Search and Filtering Enhance list commands with query parameters: ```rust PackCommands::List { #[arg(long)] enabled: Option, #[arg(long)] search: Option, #[arg(long)] limit: Option, #[arg(long)] offset: Option, } => { let mut query = vec![]; if let Some(enabled) = enabled { query.push(format!("enabled={}", enabled)); } if let Some(search) = search { query.push(format!("search={}", search)); } // Build query string and use get_with_query() } ``` **Effort:** 8-12 hours **Dependencies:** API endpoints must support PUT/DELETE (most already do) **Value:** High - completes CLI feature parity with API --- ## Priority 3: Profile and Configuration Management (Medium Impact) ### Problem - `--profile` flag declared in main.rs but not used - `attune config set api-url` command defined but not implemented - Profile switching requires manual `attune config use` command ### Suppressed Methods - `CliConfig::set_api_url()` - Direct API URL update - `CliConfig::load_with_profile()` - Load with profile override - `CliConfig::api_url()` - Get current API URL ### Implementation Plan #### 3.1: Implement `--profile` Flag Support **File:** `attune/crates/cli/src/main.rs` Currently the flag exists but is unused. Update `main()`: ```rust #[tokio::main] async fn main() -> Result<()> { let cli = Cli::parse(); // Load config with profile override let config = if let Some(profile) = &cli.profile { CliConfig::load_with_profile(Some(profile))? } else { CliConfig::load()? }; // Pass config to command handlers instead of loading fresh each time } ``` Update all command handlers to accept `&CliConfig` parameter. #### 3.2: Complete Config Set Command **File:** `attune/crates/cli/src/commands/config.rs` The `handle_set()` function exists but uses `set_value()` which only handles specific keys. Add: ```rust async fn handle_set(key: String, value: String, output_format: OutputFormat) -> Result<()> { let mut config = CliConfig::load()?; match key.as_str() { "api_url" | "api-url" => { config.set_api_url(value.clone())?; } _ => { config.set_value(&key, value.clone())?; } } // Output handling... } ``` #### 3.3: Add Config Get/Show Commands ```rust ConfigCommands::Show => { let config = CliConfig::load()?; let profile = config.current_profile()?; // Display full config including: // - Current profile // - API URL (from config.api_url()) // - Auth status // - All settings } ``` **Effort:** 3-4 hours **Dependencies:** None **Value:** Medium - improves multi-environment workflow --- ## Priority 4: Executor Monitoring APIs (Low-Medium Impact) ### Problem - No visibility into executor runtime state - Cannot inspect queue depths or policy enforcement - No way to adjust policies at runtime ### Suppressed Methods in `attune/crates/executor/src/`: - `PolicyEnforcer::new()`, `with_global_policy()`, `set_*_policy()` - `PolicyEnforcer::check_policies()`, `wait_for_policy_compliance()` - `QueueManager::get_all_queue_stats()`, `cancel_execution()`, `clear_all_queues()` - `ExecutorService::pool()`, `config()`, `publisher()` ### Implementation Plan #### 4.1: Add Executor Admin API Endpoints **New File:** `attune/crates/api/src/routes/executor_admin.rs` ```rust // Queue monitoring GET /api/v1/admin/executor/queues -> List all action queues with stats (depth, active, capacity) GET /api/v1/admin/executor/queues/{action_id} -> Detailed queue stats for specific action // Policy inspection GET /api/v1/admin/executor/policies -> List all configured policies (global, pack, action) // Policy management (future) POST /api/v1/admin/executor/policies/global -> Set global execution policy POST /api/v1/admin/executor/policies/pack/{pack_id} -> Set pack-specific policy POST /api/v1/admin/executor/policies/action/{action_id} -> Set action-specific policy // Queue operations POST /api/v1/admin/executor/queues/{action_id}/clear -> Clear queue for action (emergency) DELETE /api/v1/admin/executor/queues/{action_id}/executions/{execution_id} -> Cancel queued execution ``` #### 4.2: Expose Executor State via Message Queue **Alternative approach:** Instead of HTTP API, use pub/sub: ```rust // Executor publishes stats periodically topic: "executor.stats" payload: { "queues": [...], "policies": [...], "active_executions": 42 } // API service subscribes and caches latest stats // Serves from cache on GET /admin/executor/stats ``` #### 4.3: Add CLI Admin Commands **New File:** `attune/crates/cli/src/commands/admin.rs` ```rust #[derive(Subcommand)] pub enum AdminCommands { /// Executor administration Executor { #[command(subcommand)] command: ExecutorAdminCommands, }, } #[derive(Subcommand)] pub enum ExecutorAdminCommands { /// Show queue statistics Queues { #[arg(long)] action: Option, }, /// Show policy configuration Policies, /// Clear a queue (dangerous) ClearQueue { action: String, #[arg(long)] confirm: bool, }, } ``` **Effort:** 6-10 hours **Dependencies:** Requires deciding on HTTP API vs. message queue approach **Value:** Medium - mainly for ops/debugging, not end-user facing --- ## Non-Priority Items (Keep Suppressed) These items should remain with `#[allow(dead_code)]` for now: ### Test Infrastructure - `attune/crates/api/tests/helpers.rs` - Test helper methods - `attune/crates/cli/tests/common/mod.rs` - Mock functions - `attune/crates/executor/tests/*` - Test runtime helpers **Reason:** These are test utilities that may be used in future tests. They provide a complete test API surface even if not all methods are currently used. ### Service Internal Fields - `WorkerService.config` - Kept for potential future use - `ExecutorService.queue_name` - Backward compatibility - `Subscriber.client_id`, `user_id` - Structural completeness - `WorkflowExecutionHandle.workflow_def_id` - May be needed for advanced workflow features **Reason:** These maintain API completeness and may be needed for future features. Removing them would require breaking changes. ### Methods Only Used in Tests - `PolicyEnforcer::new()` (vs. `with_queue_manager()`) - `QueueManager::new()`, `with_defaults()` (vs. `with_db_pool()`) **Reason:** Simpler constructors useful for unit testing. Production code uses more complete constructors. --- ## Implementation Roadmap ### Phase 1: Foundation ✅ COMPLETE 1. ✅ **Token Refresh Mechanism** (Priority 1) - COMPLETE 2026-01-27 - ✅ API endpoint (already existed) - ✅ CLI client auto-refresh implemented - ✅ Manual refresh command (`attune auth refresh`) - ✅ Config file persistence of refreshed tokens - ✅ Zero warnings, fully functional - **Testing:** Auto-refresh on 401, manual refresh command tested ### Phase 2: CLI Feature Completion ✅ COMPLETE 2. ✅ **CRUD Operations** (Priority 2) - COMPLETE 2026-01-27 - ✅ Update commands implemented for actions, rules, triggers, packs - ✅ Delete commands with confirmation for actions, triggers (rules/packs already had it) - ✅ All ApiClient HTTP methods now active (PUT, DELETE) - ✅ Zero dead_code warnings for implemented features - **Testing:** All CLI tests pass (2 pre-existing auth failures unrelated) ### Phase 3: Configuration Enhancement ✅ COMPLETE 3. ✅ **Profile Management** (Priority 3) - COMPLETE 2026-01-27 - ✅ `--profile` flag fully implemented across all commands - ✅ `CliConfig::load_with_profile()` method - ✅ All command handlers updated (auth, action, rule, execution, key, sensor, trigger, pack, config) - ✅ Zero warnings, fully functional - **Testing:** All CLI tests pass with profile support ### Phase 4: Operational Visibility (Week 6-8, Optional) 4. ⏳ **Executor Monitoring** (Priority 4) - Design decision: HTTP API vs. pub/sub - Implement chosen approach - CLI admin commands - **Blockers:** Architecture decision needed - **Testing:** Requires running executor instances --- ## Success Criteria ### Phase 1 Complete ✅ - [x] Users can work with CLI for >1 hour without re-login - [x] Expired tokens automatically refresh transparently - [x] Manual `attune auth refresh` command works ### Phase 2 Complete ✅ - [x] All resources support full CRUD via CLI (Create, Read, Update, Delete) - [x] Update commands accept optional fields (label, description, etc.) - [x] Delete operations require confirmation (unless --yes flag) - [x] Users can manage entire platform lifecycle from CLI ### Phase 3 Complete ✅ - [x] `--profile dev/staging/prod` flag works across all commands - [x] `attune config set api-url ` updates current profile - [x] Multi-environment workflows seamless ### Phase 4 Complete - [ ] Operators can view executor queue depths - [ ] Policy configuration visible via API/CLI - [ ] Emergency queue operations available --- ## Risk Assessment ### Low Risk - **Token refresh:** Well-defined pattern, existing JWT infrastructure - **CRUD completion:** API endpoints mostly exist, just need CLI wiring - **Profile flag:** Simple config plumbing ### Medium Risk - **Executor monitoring:** Architecture decision required (HTTP vs. message queue) - HTTP: Simpler but requires executor to expose endpoints - Message Queue: More scalable but adds complexity - **Recommendation:** Start with HTTP for simplicity ### Dependency Risks - No major dependencies between phases - Each phase can be implemented independently - Phase 4 can be deferred if priorities change --- ## Documentation Updates Required After implementation: 1. Update `docs/cli-reference.md` with new commands 2. Update `docs/api-authentication.md` with refresh flow 3. Add `docs/cli-configuration.md` with profile examples 4. Add `docs/executor-monitoring.md` (Phase 4) 5. Update this document's status to "Complete" --- ## Alternatives Considered ### Alternative 1: Remove Suppressed Methods **Rejected:** These methods represent planned functionality with clear use cases. Removing them would require re-adding later with breaking changes. ### Alternative 2: Implement All at Once **Rejected:** Phased approach allows for incremental value delivery and testing. Phase 4 can be deferred if needed. ### Alternative 3: Auto-generate CLI from OpenAPI **Deferred:** Would eliminate need for manual CLI CRUD implementation, but requires significant tooling investment. Consider for future major version. --- ## Next Steps 1. **Review this plan** with team/stakeholders 2. **Decide on Phase 4 architecture** (HTTP vs. message queue) 3. **Create GitHub issues** for each phase 4. **Implement Phase 1** (highest impact, no blockers) 5. **Update this document** as implementation progresses --- ## Related Documentation - `attune/docs/dead-code-cleanup.md` - Warning cleanup context - `attune/docs/cli-reference.md` - Current CLI commands - `attune/docs/api-authentication.md` - Auth flow documentation - `attune/CHANGELOG.md` - Historical context on warning fixes
