Let me test if the new endpoint works by making a curl request. But first let me check if the server needs to be restarted. It's running on port 8080. Let me test the new endpoint.


Let me test the new endpoint and then create the app spec.

Good, the old processes are killed. Now let me start the server again.


cd "C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocoder-2.0" && ./venv/Scripts/python.exe -m uvicorn server.main:app --host 0.0.0.0 --port 8080

Start Autocoder server


Command running in background with ID: b7a69dd. Output is being written to: C:\Users\MIKESW~1\AppData\Local\Temp\claude\C--Users-MikeSwanson-claude-projects\tasks\b7a69dd.output


Let me wait a moment and then test the endpoint.


sleep 3 && curl -s http://localhost:8080/api/system/orphans

Test orphans endpoint after server restart


The new endpoint is working. No orphan processes found (which is expected since we just restarted). Now let me create the conversational app spec for the user.


New endpoint works. Now let me create the conversational app spec.

# Autocoder 2.0 Enhancement Spec - Conversational Format

Use this as your response during the spec creation interview. Copy/paste or adapt as needed.

---

## Initial Project Description

I want to enhance Autocoder 2.0 - this is an existing, fully functional autonomous coding agent system. It already works and I use it regularly. I'm looking to add new capabilities that will make it exceptional.

**Current stack:** Python/FastAPI backend, React/TypeScript frontend with Tailwind v4, SQLite database. But I'm open to changes if you think something would work better - feel free to suggest alternatives.

**What already exists and works well:**

- Full agent loop with pause/resume/stop controls
- Feature database with MCP server for progress tracking
- React UI with kanban board showing pending/in-progress/done features
- Real-time WebSocket updates for logs and status
- Parallel agent execution with file locking for conflict prevention
- Smart scheduler that uses AI to decide what can run in parallel
- Infrastructure context injection - agents know about my servers and credentials
- YOLO mode for rapid prototyping without browser testing
- Project registry supporting projects in any directory

**Recent bug fix already applied:**
- Process tree termination - when stopping an agent, it now kills all child processes (MCP servers, Playwright) not just the parent
- Added `/api/system/orphans` and `/api/system/cleanup` endpoints for finding and killing zombie processes

---

## What I Want to Add

In rough priority order, but you can reorder based on dependencies:

### 1. Token and Cost Tracking
I want visibility into how much each session and feature costs. Store usage data somewhere (SQLite is fine), show running cost in the UI. Maybe a little badge in the header that updates as the agent works. Historical data would be nice too - "this project has used X tokens total."

### 2. Session Recovery / Checkpointing
If the agent crashes or I accidentally close it, I want to resume where it left off instead of restarting the feature from scratch. Save state periodically - maybe every few tool calls or after each significant action. Add a `--resume` flag or make it automatic.

### 3. Better Git Integration
Auto-commit after each feature passes with a meaningful commit message derived from the feature description. Maybe create a branch per feature automatically. Would be great if it could generate PR descriptions too when I'm ready to merge.

### 4. Multi-Model Support
Different Claude models for different tasks. Use your judgment on what makes sense, but my thinking is:
- Opus for complex architectural decisions or when the agent is stuck
- Sonnet for most coding work (current default)
- Haiku for quick validations, simple checks, or summarization

Should be configurable but have smart defaults.

### 5. Learning from Past Work
Build up project knowledge over time. When the agent successfully implements a feature, cache the approach somehow. Next time it encounters something similar, it can reference what worked before. This could be as simple as saving successful implementations to a searchable index or as sophisticated as embeddings - you decide.

### 6. Visual Dashboard Improvements
- Dependency graph showing how features relate
- Token usage charts over time
- Timeline view of agent actions/decisions
- Maybe a "thinking" indicator showing what the agent is considering

---

## Guidelines for Implementation

**Don't break what's working** - This is enhancement, not rewrite. Be surgical.

**You can refactor if needed** - If an enhancement would be cleaner with some restructuring, go for it. Just make sure tests pass after.

**Each feature should be independently testable** - Don't create features that can only be verified after implementing 3 other features.

**Suggest the tech stack** - I mentioned the current stack but I trust your judgment. If you think we should use Redis for caching instead of SQLite, or add a vector database for the learning feature, suggest it.

**Consider the existing patterns** - Look at how similar things are done in the codebase and follow those patterns unless there's a good reason not to.

---

## Constraints (Don't Break These)

- Security model must remain intact - don't bypass the bash allowlist
- Database migrations if changing schema - no destructive changes
- UI changes need `npm run build` afterward (this is documented in CLAUDE.md)
- Keep the localhost-only restriction for the API
- Don't commit credentials or API keys

---

## Testing Strategy

Each feature should be verifiable by:
1. Lint passes (ruff)
2. Type check passes (if applicable)
3. Manual verification of the described behavior
4. Doesn't break existing features (basic regression)

---

## Notes for the Interview

If the spec wizard asks for clarification:

**On priority:** Token tracking and session recovery are highest priority - they help me use Autocoder more effectively right now. Git integration and multi-model are medium. Learning and visual improvements are nice-to-have.

**On scope:** Start with the core functionality, don't gold-plate. Better to have working basics than elaborate features that don't quite work.

**On architecture:** I prefer composition over inheritance, small focused modules, clear separation of concerns. Look at how `process_manager.py` or `resource_manager.py` are structured for examples.

Great, the app spec is done. Let me update the todo list to mark it as complete and provide a summary to the user.


TodoWrite

Fix zombie process bug in process_manager.py

Add orphan process cleanup utility

Add system cleanup API endpoint

Create conversational app spec for Autocoder


Todos have been modified successfully. Ensure that you continue to use the todo list to track your progress. Please proceed with the current tasks if applicable

Fix zombie process bug in process_manager.py

Add orphan process cleanup utility

Add system cleanup API endpoint

Create conversational app spec for Autocoder

Add orphan process cleanup utility

Add system cleanup API endpoint


All done. Let me provide a summary to the user.


Done. Here's what I completed:

## Zombie Process Fix (Applied Now)

**`server/services/process_manager.py`:**
- Added `_kill_process_tree()` method that uses `psutil.Process(pid).children(recursive=True)` to find all descendants
- Updated `stop()` to kill the entire process tree, not just the parent
- Added `find_orphan_processes()` to scan for stray Autocoder processes
- Added `kill_orphan_processes()` to clean them up

**`server/routers/system.py`** (new file):
- `GET /api/system/orphans` - List orphaned processes
- `POST /api/system/cleanup` - Kill orphaned processes
- `GET /api/system/health` - Extended health check with orphan count

**Server restarted and tested:**
```
curl http://localhost:8080/api/system/orphans
{"count":0,"processes":[]}
```

---

## Conversational App Spec

Created **`APP_SPEC_CONVERSATION.md`** with copy-paste ready content for the spec interview. Includes:

1. **Token/Cost Tracking** - Usage visibility in UI
2. **Session Recovery** - Resume crashed sessions
3. **Git Integration** - Auto-commit, branches, PR descriptions
4. **Multi-Model Support** - Opus/Sonnet/Haiku routing
5. **Learning System** - Cache successful implementations
6. **Visual Improvements** - Dependency graphs, usage charts

The spec is conversational, gives Claude flexibility on implementation details, and emphasizes not breaking existing functionality.

---

**Server running at:** http://localhost:8080

Ready to use the spec wizard whenever you want.


The old background task (b858320) failed, which is expected since I killed that process and started a new one (b7a69dd). Let me verify the new server is still running and things are working properly.


That's the old server task I killed to restart with the new code. The new server (b7a69dd) is running. Let me verify:


Bash

curl -s http://localhost:8080/api/health && echo "" && curl -s http://localhost:8080/api/system/health

Verify server is healthy


{"status":"healthy"}
{"status":"healthy","orphan_count":0,"has_orphans":false}


The new server is running fine. Everything is working properly.


Server is healthy with all new endpoints working:

- **Basic health:** `{"status":"healthy"}`
- **System health:** `{"status":"healthy","orphan_count":0,"has_orphans":false}`

The new process cleanup functionality is live. When you stop agents now, they'll kill the entire process tree (MCP servers included), and you have manual cleanup endpoints if needed.


Update conversational app spec prompt with everything we've talked about so far.


The user wants me to update the conversational app spec to include everything we've discussed. Let me think about what's been covered:

1. The original enhancements I suggested (token tracking, session recovery, git integration, multi-model, learning, visual improvements)
2. The zombie process fix that was already applied
3. The items from the ARCHITECTURE.md "Items to Make Exceptional" section

Let me create a comprehensive update that captures all of this.


Write

# Autocoder 2.0 Enhancement Spec - Conversational Format

Use this as your response during the spec creation interview. Copy/paste or adapt as needed.

---

## Initial Project Description

I want to enhance Autocoder 2.0 - this is an existing, fully functional autonomous coding agent system. It already works and I use it regularly. I'm looking to add new capabilities that will make it exceptional.

**Current stack:** Python/FastAPI backend, React/TypeScript frontend with Tailwind v4, SQLite database. But I'm open to changes if you think something would work better - feel free to suggest alternatives or refactor if it makes the enhancements cleaner.

---

## What Already Exists and Works

**Core Agent System:**
- Two-agent pattern: Initializer creates features from app spec, Coding agent implements them
- Full agent loop with pause/resume/stop controls
- YOLO mode for rapid prototyping (skips browser testing)
- Auto-continuation between sessions with 3-second delay

**Feature Management:**
- SQLite database with priority, category, name, description, steps, status
- MCP server exposing 7 tools (get_stats, get_next, mark_passing, etc.)
- Kanban board UI showing pending/in-progress/done

**Parallel Execution:**
- `parallel_agent.py` - Run multiple agents on non-conflicting features
- `smart_orchestrator.py` - AI-driven parallelization decisions
- `feature_graph.py` - Tracks file conflicts between features
- `file_lock_manager.py` - Async-safe locking for concurrent access

**Infrastructure Awareness:**
- `credential_resolver.py` - Parses credentials.md for server access
- `resource_manager.py` - Tracks servers/services with SSH verification
- `resource_context.py` - Merges global + project resources
- Context injection into agent prompts (agents know about my infrastructure)

**UI & Real-time:**
- React 18 with TanStack Query, Radix UI components
- Neobrutalism design system with custom animations
- WebSocket for real-time logs, status, and feature updates
- Project registry supporting projects in any directory
- Folder browser for project selection
- Multi-step project creation wizard with spec interview

**Server Architecture:**
- FastAPI with 77 API routes across 11 routers
- Localhost-only security middleware
- Services: AgentRunner, SessionManager, SpecGenerator, SmartScheduler, etc.

**Recent Bug Fix (Already Applied):**
- Process tree termination - stopping an agent now kills all child processes (MCP servers, Playwright)
- Added `/api/system/orphans` and `/api/system/cleanup` endpoints for zombie cleanup
- Uses `psutil.Process.children(recursive=True)` for thorough cleanup

---

## What I Want to Add

### Priority 1: Observability & Reliability

**1. Token and Cost Tracking**
I want visibility into how much each session and feature costs. Store usage data in SQLite, show running cost in the UI header as a badge that updates in real-time. Include:
- Tokens per session (input/output breakdown)
- Cost estimate using current Anthropic pricing
- Historical data - "this project has used X tokens / $Y total"
- Per-feature cost attribution

**2. Session Recovery / Checkpointing**
If the agent crashes or I close it accidentally, resume where it left off instead of restarting. Save state periodically - every few tool calls or after significant actions. Options:
- Add `--resume` flag to CLI
- Or make it automatic - detect incomplete session and offer to resume
- Store checkpoint in project directory (`.agent_checkpoint.json` or similar)

**3. Better Error Recovery**
When the agent gets stuck or fails repeatedly on a feature:
- Detect the stuck state (same error 3+ times)
- Option to escalate to a more capable model (Opus)
- Option to skip and move to next feature
- Log detailed failure info for later analysis

### Priority 2: Developer Experience

**4. Git Integration**
Automate version control during development:
- Auto-commit after each feature passes with meaningful message derived from feature description
- Option to create branch per feature (`feature/feature-name`)
- Generate PR descriptions when ready to merge
- Handle merge conflicts with AI assistance (or at least flag them clearly)

**5. Multi-Model Support**
Route tasks to appropriate models:
- **Opus** - Complex architectural decisions, when stuck, analyzing large codebases
- **Sonnet** - Standard coding work (current default)
- **Haiku** - Quick validations, linting decisions, simple checks, summarization

Implementation ideas:
- Config file for model routing rules
- Or let the orchestrator decide dynamically based on task complexity
- Fallback chain: try Haiku first, escalate if it struggles

**6. Improved Logging & Debugging**
- Structured logs with levels (debug/info/warn/error)
- Log viewer in UI with filtering
- Export logs for a session
- "Why did it do that?" - trace reasoning for specific actions

### Priority 3: Intelligence & Learning

**7. Learning from Past Work**
Build project knowledge over time:
- When a feature passes, index the implementation approach
- On similar future features, retrieve relevant past solutions
- Could be simple (keyword search over saved implementations) or sophisticated (embeddings)
- Project-specific knowledge base that grows over time

**8. Smarter Feature Prioritization**
Go beyond simple priority numbers:
- Detect dependencies automatically from code analysis
- Suggest optimal ordering based on complexity and risk
- Flag features that might conflict or have shared dependencies
- "This feature should come after X because it depends on Y"

### Priority 4: Visual & UX Improvements

**9. Visual Dashboard**
- Dependency graph showing how features relate (D3.js or similar)
- Token usage charts over time
- Timeline view of agent actions
- "Thinking" indicator showing what agent is considering
- Cost breakdown by feature/session

**10. Enhanced Agent Controls**
- "Retry with Opus" button for stuck features
- Queue management - reorder pending features via drag-drop
- Bulk operations - skip multiple, reprioritize
- Estimated time/cost for remaining work

---

## Architecture Considerations

**Plugin/Extension System (Future)**
For extensibility, consider:
- Pre/post implementation hooks
- Custom MCP tools that can be added per-project
- Custom validators for project-specific requirements
- Would make Autocoder adaptable to different workflows

**Cost Optimization**
- Per-project token budgets with warnings
- Prompt optimization - don't repeat unchanged context
- Cache common operations
- Usage analytics and trend detection

---

## Guidelines for Implementation

**Don't break what's working** - This is enhancement, not rewrite. The current system works well.

**You can refactor if needed** - If an enhancement would be cleaner with restructuring, go for it. Just ensure existing functionality still works.

**Each feature should be independently testable** - No features that require 3 other things to verify.

**Suggest the tech stack** - If you think Redis would be better for caching, or we need a vector DB for learning, suggest it. I trust your judgment.

**Follow existing patterns** - Look at how `process_manager.py`, `resource_manager.py`, or the MCP server are structured. Consistent style matters.

**Consider the parallel execution model** - New features should work correctly when multiple agents run simultaneously.

---

## Constraints (Don't Break These)

- Security model must remain intact - don't bypass bash allowlist in `security.py`
- Database migrations if changing schema - no destructive changes to `features.db`
- UI changes need `npm run build` afterward
- Keep localhost-only restriction for API (security middleware in `main.py`)
- Don't commit credentials or API keys
- Process cleanup must work - don't spawn processes that can become orphans

---

## Testing Strategy

Each feature should be verifiable by:
1. Lint passes (ruff)
2. Type check passes (pyright/mypy if configured)
3. Manual verification of described behavior
4. Doesn't break existing features (run agent on a test project)
5. Process cleanup still works (no zombies)

## Notes for Interview Clarifications

**On priority:** Token tracking and session recovery are highest - they help me immediately. Git integration and multi-model are medium priority. Learning and visual improvements are nice-to-have.

**On scope:** Start with core functionality, don't gold-plate. Working basics beat elaborate features that don't quite work.

**On architecture:** Prefer composition over inheritance, small focused modules, clear separation. The existing services are good examples.

**On the learning feature:** Start simple - even just saving successful implementations as searchable markdown would be valuable. Don't need vector embeddings immediately.

**On multi-model:** Config-driven is fine initially. Dynamic routing can come later.
