This analysis identifies the root causes and provides solutions that can reduce execution time to 5-7 minutes. + +## Performance Breakdown + +### Current State (Before Optimizations) +- **Total execution time**: ~20 minutes +- **Claude AI Assistant step**: 10m51s + - Actual Claude execution: ~2.5 minutes + - Setup/installation: ~2 minutes + - MCP server shutdown wait: ~6 minutes +- **Job cleanup**: 7-9 minutes + +### Root Causes Identified + +#### 1. MCP Server Shutdown Issues (6 minutes delay) +The MCP servers (gitea-mcp-server.ts and local-git-ops-server.ts) were not shutting down properly after Claude completed execution. They use StdioServerTransport which keeps stdin/stdout connections open, waiting for an EOF signal that never arrived. + +**Impact**: 6 minutes of unnecessary waiting + +#### 2. Container Layering +The workflow uses a nested container setup: +```yaml +runs-on: ubuntu-latest +container: + image: node:18-bullseye +``` +This creates multiple container layers that significantly increase cleanup time. + +**Impact**: 5-6 minutes of additional cleanup time + +#### 3. Failed Cache Attempts +Multiple components attempt to use caching but fail with timeout errors: +- Bun package cache +- Node.js cache +- npm cache + +**Impact**: 10-20 seconds per cache attempt, plus error noise in logs + +#### 4. Duplicate Package Installation +The action installs packages twice: +- First bun install for action dependencies +- Second bun install for claude-code package + +**Impact**: ~3-4 seconds (minor but unnecessary) + +## Implemented Solutions + +### 1. Fixed MCP Server Shutdown +Added proper shutdown handling to both MCP servers: +- Listen for stdin EOF signal +- Properly close transport connections +- Add signal handlers for SIGTERM, SIGINT, SIGHUP +- 5-minute timeout as safety net + +**Expected savings**: 6 minutes + +### 2. Disabled Caching +Added `cache: false` to Bun setup to avoid timeout errors. + +**Expected savings**: 10-20 seconds, cleaner logs + +### 3. Created Optimized Workflow +Provided claude-optimized.yml that removes the container layer. + +**Expected savings**: 5-6 minutes in cleanup time + +### 4. Custom Container Option +Created Dockerfile.runner for a pre-built container with all dependencies. + +**Expected savings**: 1-2 minutes in setup time + +## Expected Results + +### With Current Workflow + MCP Fixes +- Total time: **~11-13 minutes** (down from 20) +- Savings: ~7-9 minutes (35-45% improvement) + +### With Optimized Workflow (No Container Layer) +- Total time: **~6-7 minutes** (down from 20) +- Savings: ~13-14 minutes (65-70% improvement) + +### With Custom Pre-built Container +- Total time: **~5-6 minutes** (down from 20) +- Savings: ~14-15 minutes (70-75% improvement) + +## Recommendations + +### Immediate Actions (No Infrastructure Changes) +1. **Deploy the MCP server fixes** - This alone saves 6 minutes +2. **Monitor the logs** to confirm MCP servers shut down immediately after Claude completes + +### Short-term Optimizations +1. **Switch to the optimized workflow** (remove container layer) for additional 5-6 minute savings +2. **Test with different runner configurations** if available in your Gitea setup + +### Long-term Optimizations +1. **Build and use custom container image** with pre-installed dependencies +2. **Consider runner-level optimizations**: + - Use SSD storage for faster Docker operations + - Allocate more resources to runners + - Use local Docker registry for faster image pulls +3. **Optimize the base action** to reduce duplicate installations + +## Additional Findings + +### Token Permissions +The action requires specific token scopes: +- `write:repository` - For code changes (already working) +- `write:issue` - For commenting on issues +- `write:pull_request` - For creating PRs + +Ensure your `RUNNER_ACCESS_TOKEN` has all required scopes. + +### OAuth Authentication +OAuth authentication via `claude_credentials` is working correctly after: +- Extracting access token from credentials JSON +- Passing via `claude_code_oauth_token` parameter +- Setting `CLAUDE_CODE_OAUTH_TOKEN` environment variable + +## Monitoring + +After implementing these changes, monitor: +1. MCP server shutdown logs - Should show "Stdin closed, shutting down..." +2. Total step execution times in Gitea UI +3. Any remaining timeout or connection errors + +## Conclusion + +The performance issues were primarily caused by improper MCP server shutdown handling and unnecessary container layering. The implemented fixes should reduce execution time by 65-75%, bringing a 20-minute workflow down to 5-7 minutes. \ No newline at end of file
