- Summary of conflicts resolved - - How we adapted to new auth pattern - - Test results showing isolation works - -2. **Create comprehensive commit message**: - ``` - merge: integrate main branch with Agent Manager changes - - - Adapt to middleware-based authentication from PR #4338 - - Remove verify_secret_key in favor of middleware auth - - Update AppState initialization to match new signature - - Preserve all Agent Manager functionality for per-session isolation - - Keep graceful shutdown improvements for cleanup task - - This completes the Agent Manager POC addressing Discussion #4389: - - Each session gets its own isolated agent - - Extensions don't interfere between sessions - - Cleanup task manages memory with graceful shutdown - - Foundation laid for scheduler/recipe integration - ``` - -## Rationale for This Approach - -### Why Agent Manager Matters -The shared agent in goose-server was causing: -- Extension state leaking between sessions -- Race conditions in multi-user scenarios -- Inability to run parallel sessions safely -- Blocked path to proper multi-user support - -### Why the Merge is Complex -Main branch made a fundamental change to authentication: -- Old: Each route verified auth with `verify_secret_key(&headers, &state)` -- New: Middleware handles auth before routes are called -- Impact: Every route we modified needs adaptation - -### Why We Must Preserve Our Work -The Agent Manager solves critical architectural issues: -- Enables true multi-session support (requirement for production) -- Unblocks scheduler integration (each job gets clean agent) -- Foundation for recipe/subagent unification (as per Discussion #4389) -- Already has comprehensive test coverage proving it works - -## Success Criteria -1. ✅ All tests pass after merge -2. ✅ Two concurrent sessions can use different extensions without interference -3. ✅ Cleanup task properly manages idle agents -4. ✅ No regressions in existing functionality -5. ✅ PR ready for review with clear documentation of changes - -## Important Notes -- Do NOT lose the `AgentManager` implementation - it's the core value -- Do NOT accept any merge resolution that breaks per-session isolation -- The auth changes are just mechanical updates -

-## Architecture Concerns - -### 1. Session Identifier Handling -- **Current**: Using `session::Identifier::Name(string)` everywhere, but the enum also has `Id(u64)` variant -- **Concern**: Inconsistent identifier types could lead to confusion. Should standardize on one approach or clearly document when to use each -- **Impact**: Medium - Could cause bugs if different parts of the system use different identifier types - -### 2. Agent Creation Without Provider -- **Current**: `create_agent_for_session()` creates agents without providers, relying on later API calls to set them -- **Concern**: Agents in an incomplete state could cause runtime errors if accessed before provider is set -- **Impact**: High - Could cause crashes or undefined behavior - -### 3. Cleanup Task Lifecycle -- **Current**: `spawn_cleanup_task()` creates a detached tokio task that runs forever -- **Concern**: No graceful shutdown mechanism, task continues running even after AgentManager is dropped -- **Impact**: Low - Resource leak on shutdown, but process termination will clean up - -## Implementation Concerns - -### 4. Lock Contention -- **Current**: Using RwLock for the agents HashMap, but many operations need write locks -- **Concern**: `get_agent()` upgrades from read to write lock if agent doesn't exist, causing potential contention -- **Impact**: Medium - Performance degradation under high concurrency - -### 5. Metrics Accuracy -- **Current**: Metrics use separate RwLock and can become inconsistent with actual agent state -- **Concern**: Race conditions between metric updates and agent operations -- **Impact**: Low - Only affects monitoring/debugging - -### 6. Error Handling Inconsistency -- **Current**: Mix of `AgentError` in manager and `anyhow::Error` in routes -- **Concern**: Loss of error context during conversion, making debugging harder -- **Impact**: Low - Mainly affects error messages and debugging - -## Integration Concerns - -### 7. Backward Compatibility -- **Current**: Routes still accept optional `session_id`, auto-generating if missing -- **Concern**: Old clients might not provide session_id, leading to orphaned sessions -- **Impact**: Medium - Memory leak from uncleaned sessions - -### 8. Extension Isolation -- **Current**: Extensions are added per-agent, but frontend extensions might have global state assumptions -- **Concern**: Frontend extensions weren't designed for per-session isolation -- **Impact**: High - Could break existing extension behavior - -### 9. Session Persistence -- **Current**: Session metadata and messages saved separately, potential for inconsistency -- **Concern**: Race conditions between metadata and message saves -- **Impact**: Medium - Could lead to corrupted session state - -## Missing Functionality - -### 10. Resource Limits -- **Current**: `max_agents` config exists but isn't enforced -- **Concern**: Unbounded agent creation could exhaust memory -- **Impact**: High - DoS vulnerability - -### 11.

Execution Modes Not Fully Implemented -- **Current**: ExecutionMode enum defined but not used in agent creation -- **Concern**: SubTask mode with parent relationships not implemented -- **Impact**: Low - Feature incomplete but doesn't break existing functionality - -## Testing Concerns - -### 13. Test Coverage Gaps -- **Current**: Tests cover basic functionality but miss edge cases -- **Missing**: Provider lifecycle tests, concurrent session operations, cleanup during active operations -- **Impact**: Medium - Bugs might slip through to production - -### 14. Mock Provider in Tests -- **Current**: Some tests use real providers, others use mocks inconsistently -- **Concern**: Tests might pass with mocks but fail with real providers -- **Impact**: Low - Test reliability issues - -## Performance Concerns - -### 15. Memory Management -- **Current**: Agents kept in memory until idle timeout -- **Concern**: Long-running sessions consume memory indefinitely -- **Impact**: Medium - Memory growth over time - -### 16.

- `schedule_id: Option` - For scheduled jobs - - `execution_mode: Option` - foreground/background - - `max_turns: Option` - Max iterations - - `retry_config: Option` - Retry settings - -- **SessionMetadata** stored in JSONL files: - - Description, message count, token usage - - Working directory - - TODO list content (session-scoped) - - Schedule ID if triggered by scheduler - -- Sessions are file-based (JSONL format) with: - - First line: metadata - - Subsequent lines: messages - - Atomic file operations for safety - - Corruption recovery mechanisms - -### Server Integration (crates/goose-server/src/state.rs) -- **AppState** holds single Agent instance: - - `agent: Option` where `AgentRef = Arc` - - Single agent serves all sessions/requests - - Scheduler is also stored in AppState - -### Request Routing (crates/goose-server/src/routes/reply.rs) -- Each `/reply` request creates a new async task -- SessionConfig created per request with: -

-### Concurrency Analysis -- **Single Agent, Multiple Sessions**: One Agent instance handles all concurrent sessions -- **Mutex Protection**: Most Agent fields protected by Mutex locks - - Provider, sub_recipe_manager, frontend_tools, prompt_manager, etc. - - Each field locked independently when accessed -- **Shared State Issues**: - - Extensions loaded globally in ExtensionManager - - Tool monitors shared across sessions - - Provider instance shared (Arc) - - Scheduler service shared - - Frontend tools and instructions shared - -### MCP/Extension Architecture -- **ExtensionManager** (crates/goose/src/agents/extension_manager.rs): - - Contains `extensions: Mutex>` - - Each Extension holds: - - MCP client connection (Arc>>) - - Server info and configuration - - Optional temp directory for inline Python extensions - - Extensions are agent-wide, not per-session - - All sessions share the same extension connections -

-2. **Tool Monitor Conflicts**: - - Tool repetition monitoring shared across sessions - - One session's tool usage affects another's limits - -3. **Provider Changes**: - - Updating provider affects all active sessions - - Model configuration changes mid-session - -4. **Channel Conflicts**: - - confirmation_tx/rx channels shared - - tool_result_tx/rx channels shared - - Messages from different sessions could interleave - -5. **Recipe/Sub-recipe State**: - - final_output_tool shared - - sub_recipe_manager shared - - One session's recipe affects another - -### Design Considerations for One-Agent-Per-Session - -#### Memory Implications -- **Current**: ~1 Agent instance regardless of sessions -- **Per-Session**: N agents for N concurrent sessions -- **Overhead per Agent**: - - Base Agent struct: ~500 bytes - - Extension connections: Variable (1-10MB per extension) - - Provider instance: ~1-5MB - - Channels and buffers: ~100KB - - **Estimated**: 5-20MB per agent instance - -#### Resource Management -- **MCP Connections**: - - Current: Shared connections, resource efficient - - Per-Session: Duplicate connections per session - - Impact: More file descriptors, network connections, subprocesses - -- **File Handles**: - - Session files already per-session - - Extension processes would multiply - -#### Extension Lifecycle -- **Current Issues**: - - Extensions persist across sessions - - State contamination possible - - Resource leaks accumulate - -- **Per-Session Benefits**: - - Clean extension state per session - - Isolated failures - - Better resource cleanup - -#### Performance Impact -- **Pros**: - - No lock contention between sessions - - True parallel execution - - Isolated failures - - Better scaling for multi-user - -- **Cons**: - - Higher memory usage - - Slower session startup (extension init) - - More OS resources (processes, connections) - - Potential for resource exhaustion - -## Summary - -Research complete. The current architecture uses a single Agent instance shared across all sessions, protected by multiple Mutex locks. This creates several concurrency issues: - -1. **Shared extension state** - All sessions share MCP connections -2. **Tool monitor conflicts** - Usage limits affect all sessions -3. **Channel interleaving** - Messages can mix between sessions -4. **Recipe state leaks** - Recipe tools persist across sessions -5. **Provider changes** - Updates affect all active sessions - -Moving to one-agent-per-session would provide: -- **Benefits**: Complete isolation, no lock contention, better security, true multi-user support -- **Costs**: 5-20MB per session, more connections/processes, slower startup - -Recommendation: Implement a phased migration with an agent pool pattern, fixing critical issues first while gradually moving to per-session agents with resource optimization. diff --git a/CONDENSED_PROMPT.md b/CONDENSED_PROMPT.md deleted file mode 100644 index c47d9761a98b..000000000000 --- a/CONDENSED_PROMPT.md +++ /dev/null @@ -1,41 +0,0 @@ -## Operation Guidelines - -### Long Operations (>30s) -- Inform user of duration/checkpoints -- Break into verifiable steps with progress reports -- Set iteration limits, timeouts, and resource safeguards -- Save intermediate results frequently -- Test with small cases first to estimate timing - -### Output & File Management -- **MANDATORY**: Validate all outputs meet requirements -- Save critical outputs before proceeding -- Verify: size, format, structure, checksums -- Backup before overwriting -- Test downstream compatibility before completion - -### Algorithm Termination -- Define clear termination conditions upfront -- Set max iterations, convergence thresholds, timeouts -- Monitor progress metrics for early stopping -- Log iterations for debugging -- Handle edge cases preventing termination - -### Requirements Analysis -- **CRITICAL**: Document explicit AND implicit requirements -- Break into measurable, testable components -- Document assumptions, edge cases, boundaries -- Create objective acceptance criteria -- Clarify ambiguities before implementation - -### Implementation Best Practices -- **Input validation**: null, empty, negative, wrong type -- **Verification**: After EVERY operation, confirm success before proceeding -- **Incremental approach**: Working baseline → test frequently → small changes -- **Non-blocking execution**: Use `screen -dmS` for servers, non-interactive modes (`vim -c`) -- **Data safety**: Verify archives before deletion, atomic operations, config backups -- **Debugging**: Read errors carefully, verify assumptions, test minimal cases, check syntax/typos -- **Exploration**: Examine all states/branches/configurations thoroughly -- **Robustness**: Handle unexpected inputs, provide clear errors, ensure repeatable execution -- Use subagents for verification/exploration when possible - diff --git a/CONTRIBUTING.md b/CONTRIBUTING.md deleted file mode 100644 index 85dfc6c78078..000000000000 --- a/CONTRIBUTING.md +++ /dev/null @@ -1,242 +0,0 @@ -# Contribution Guide - -Goose is open source! - -We welcome pull requests for general contributions!

While they serve different use cases, their significant shared infrastructure suggests they could be cleanly combined into a unified system. The key is preserving the simplicity of dynamic tasks while allowing optional access to the power of subrecipes. - -### Key Insights - -1. **Both systems are fundamentally the same** at the execution level -2. **The distinction is primarily in configuration and parameterization** -3. **Unification is technically feasible** and would reduce complexity -4. **A gradual migration path** exists through the shared TasksManager - -### Final Recommendation - -**Yes, dynamic tasks could be specified as subrecipes** by treating them as inline recipes with minimal configuration. This would: -- Reduce code duplication -- Provide a consistent mental model -- Enable progressive enhancement from simple to complex tasks -- Maintain backward compatibility through adapter patterns - -The path forward should focus on unifying the execution model first, then gradually converging the configuration and parameterization systems while maintaining the ease of use that makes dynamic tasks valuable. diff --git a/EFFECTIVENESS_IMPLEMENTATION_PLAN.md b/EFFECTIVENESS_IMPLEMENTATION_PLAN.md deleted file mode 100644 index 133b7e995fbb..000000000000 --- a/EFFECTIVENESS_IMPLEMENTATION_PLAN.md +++ /dev/null @@ -1,567 +0,0 @@ -# Effectiveness Implementation Plan: Option C (Pure Enhancement) - -## Executive Summary - -This plan details the implementation of multi-file edit and code search steering capabilities for Goose through **pure enhancement** of existing tools, requiring zero new tools and only ~250-350 lines of code.

The system's strength lies in: - -1. **Complete Agent Isolation**: Each job runs in its own context -2. **Flexible Architecture**: Trait-based design enables extensibility -3. **Robust State Management**: Comprehensive tracking and persistence -4. **Graceful Error Handling**: Multiple recovery strategies -5. **Production Readiness**: Health monitoring, logging, and diagnostics - -The scheduler successfully decouples long-running agent tasks from the main application loop, enabling true autonomous operation while maintaining system stability and user control. The architecture provides a solid foundation for future enhancements while remaining maintainable and testable. - -### Key Takeaways - -- **Agents run outside the main loop** through spawned Tokio tasks or Temporal workflows -- **Each job gets a fresh agent instance** ensuring complete isolation -- **Recipes define agent behavior** including prompts, extensions, and settings -- **State is carefully managed** through persistent storage and in-memory tracking -- **The system is extensible** through trait-based design and factory patterns -- **Error handling is comprehensive** with fallbacks and recovery mechanisms -- **Concurrency is well-managed** using async/await and proper synchronization - -This architecture enables Goose to run scheduled AI tasks reliably and autonomously, making it suitable for production workloads requiring scheduled agent execution. - ---- - -*Report compiled: 2025-08-27* -*Based on source code analysis of the Goose project* diff --git a/UNIFICATION_GITHUB_ISSUE.md b/UNIFICATION_GITHUB_ISSUE.md deleted file mode 100644 index d4e92c185fcf..000000000000 --- a/UNIFICATION_GITHUB_ISSUE.md +++ /dev/null @@ -1,145 +0,0 @@ -# Unify Agent Execution: per‑session agents, unified tasks/recipes/scheduler - -## Why - -Today we have several parallel ways to run “the same thing” (an agent doing work): - -- Interactive chat in goosed/goose-server uses a single shared Agent for all sessions (see goose-server AppState holding one AgentRef). -- The scheduler (legacy and Temporal) spins up a fresh Agent per run (see `run_scheduled_job_internal` in `crates/goose/src/scheduler.rs`). -- Dynamic tasks create subagents on demand (see `subagent_handler.rs`), often via the `dynamic_task__create_task` tool. -- Sub‑recipes execute either by spawning the CLI (`goose run --recipe …`) or via subagent execution (`inline_recipe`). - -This creates duplicated code paths, inconsistent behavior, and hard‑to‑debug concurrency issues: - -- Extension/provider setup logic is re‑implemented in multiple places. -- Shared Agent in the server means sessions interfere with each other (shared ExtensionManager, tool monitor, channels). -- Different execution surfaces behave differently (e.g., scheduler vs chat vs sub‑recipes via CLI). -- It makes multi‑session and multi‑user support brittle. - -We want one clear model that scales: agent per session, multiple simultaneous sessions, ad‑hoc dynamic tasks, and a single execution pipeline used by chat, scheduler, and recipes. - -## Goals - -- Agent per session in goosed/goose-server, with isolation and support for many simultaneous sessions. -- Unify execution for recipes, dynamic tasks, and scheduled jobs. -- Allow agents to create ad‑hoc dynamic tasks that run in a controlled “agent class” (subagent or inline recipe) with clear extension scoping. -- Keep existing tools usable (dynamic_task, subagent__execute_task, scheduler tools), but route them through the same backend. - -## What this looks like (examples) - -1) Two independent chat sessions at the same time - -- Session A enables only “developer” tools and uses Model X. -- Session B enables “browser” tools and uses Model Y. -- Because each session has its own Agent, there’s no cross‑talk: enabling/disabling extensions in A doesn’t affect B. - -2) Ad‑hoc fan‑out tasks from chat - -- From Session A, the agent creates two dynamic tasks and runs them in parallel with limited extensions: - -```json -{ - "tool": "dynamic_task__create_task", - "arguments": { - "task_parameters": [ - { "instructions": "Write a quick unit test for foo()", "extensions": ["developer"] }, - { "instructions": "Draft a README section summarizing today’s work", "extensions": [] } - ], - "execution_mode": "parallel" - } -} -``` - -- Both tasks run as inline recipes under the same Session A context, using the unified executor.

You can use environment variables to change things on the fly without redoing +your configuration. + +> [!TIP] +> At the moment, we are still updating some of the CLI configuration to make sure this is +> respected. + +You can change the provider goose points to via the `GOOSE_PROVIDER` env var. If you already +have a credential for that provider in your keychain from previously setting up, it should +reuse it. For things like automations or to test without doing official setup, you can also +set the relevant env vars for that provider. For example `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, +or `DATABRICKS_HOST`.
