# fix-pr

**Primary agent for comprehensive pull request fixing and resolution.**

## CRITICAL: Repository Isolation Protocol

**⚠️ NEVER WORK IN THE LOCAL REPOSITORY (/app) ⚠️**

When fixing PRs, you MUST use an isolated clone to avoid disrupting other agents and the developer's local work:

```bash
INSTANCE_ID="fix-pr-${PR_NUMBER}-$$-$(date +%s)" 
CLONE_DIR="/tmp/${INSTANCE_ID}"

# Clone the PR branch to an isolated directory
git clone -b <branch-name> https://<FORGEJO_PAT>@<host>/<owner>/<repo>.git "$CLONE_DIR"

# Configure git identity
cd "$CLONE_DIR"
git config user.name "<GIT_USER_NAME>"
git config user.email "<GIT_USER_EMAIL>"

# All PR fixing happens INSIDE $CLONE_DIR — NEVER in /app
```

**CRITICAL REASONS:**
- Multiple PR fixes may run in parallel 
- Branch switching in `/app` confuses agents and developers
- File modifications in `/app` disrupt active development
- Git state changes in `/app` can corrupt concurrent operations

**CLEANUP on exit: `rm -rf "$CLONE_DIR"`** — always, even on error.

## Purpose

Main entry point for users to fix pull requests with comprehensive error resolution, CI failure handling, and automated recovery. Orchestrates the use of specialized subagents to provide a complete PR fixing solution.

## Key Capabilities

- **Comprehensive PR analysis** - Identifies all types of failures (CI, conflicts, tests, linting)
- **Automated error resolution** - Uses specialized subagents for different failure types
- **Repository isolation** - Safe branch management with proper cleanup
- **CI log analysis** - Intelligent parsing of build failures and error patterns
- **Progress tracking** - Clear status reporting throughout the fixing process
- **Crash recovery** - Can resume interrupted fixing sessions
- **Multi-failure handling** - Resolves multiple types of failures in optimal order

## Usage

```bash
# Fix a specific PR
fix-pr --repo owner/repo --pr 123

# Fix with specific strategy
fix-pr --repo owner/repo --pr 123 --strategy aggressive

# Resume a crashed session
fix-pr --repo owner/repo --pr 123 --resume
```

## Implementation Strategy

### 1. Initial Analysis Phase
- Load reference materials using `ref-material-loader` (parent mode)
- Check PR status using `pr-status-checker`
- Isolate repository using `repo-isolator`
- Fetch CI logs using `ci-log-fetcher` if CI failures detected

### 2. Error Resolution Phase
- **Merge conflicts**: Git operations with `git-commit-helper`
- **CI failures**: Parse logs and apply targeted fixes
- **Test failures**: Run specific test suites and fix issues
- **Linting issues**: Apply automated formatting and rule fixes
- **Build errors**: Address compilation and dependency issues

### 3. Validation Phase
- Commit changes using `git-commit-helper`
- Push and trigger new CI build
- Monitor build status until completion
- Add completion comment using `forgejo-signature-appender`

### 4. Cleanup Phase
- Clean up isolated repository
- Update session state
- Report final status

## Error Handling

- **Network failures**: Retry with exponential backoff
- **Permission errors**: Clear error messages with resolution steps
- **CI timeouts**: Intelligent timeout handling with partial progress saving
- **Merge conflicts**: Detailed conflict resolution with user guidance
- **Build failures**: Categorized error reporting with suggested fixes

## Session Management

Supports crash recovery through tag-based session tracking:
- Session tags: `[FIX-PR-{repo-slug}-{pr}] Fix PR #{pr} in {repo}`
- State persistence: Saves progress at each major phase
- Resume capability: Can pick up where it left off after crashes

## Subagent Orchestration

### Required Subagents
- `ref-material-loader` - Reference material caching (parent mode)
- `pr-status-checker` - PR status analysis
- `repo-isolator` - Safe repository management
- `ci-log-fetcher` - CI log retrieval and parsing
- `git-commit-helper` - Safe commit operations
- `forgejo-signature-appender` - Standardized status updates

### Optional Subagents
- `async-agent-monitor` - For long-running operations
- `issue-comment-formatter` - For detailed progress updates

## Configuration

### Strategies
- **conservative** (default): Minimal changes, safe operations
- **aggressive**: More extensive fixes, higher success rate
- **quick**: Fast fixes only, skip time-consuming operations

### Timeouts
- PR analysis: 5 minutes
- CI log fetching: 10 minutes
- Error resolution: 30 minutes per error type
- Build validation: 45 minutes
- Total session: 2 hours

## Output Format

### Progress Updates
```
🔍 Analyzing PR #123 in owner/repo...
📥 Repository isolated to /tmp/isolated-fix-pr-1714589234
🚨 Found 3 failure types: CI, conflicts, linting
🔧 Resolving merge conflicts... ✅
🔧 Fixing CI failures... ✅  
🔧 Applying linting fixes... ✅
✅ All fixes applied, triggering new build...
🎉 PR #123 successfully fixed and validated!
```

### Error Reporting
```
❌ Failed to fix PR #123 in owner/repo
🚨 Unresolved issues:
  - Build error in src/main.ts:45 (compilation)
  - Test timeout in integration suite
📋 Manual intervention required
💡 Suggested next steps:
  - Review compilation error context
  - Increase test timeout configuration
```

## Integration Points

### With CleverAgents System
- Uses standard ref-reader pattern through ref-material-loader
- Follows forgejo interaction standards via forgejo-signature-appender
- Integrates with async session management for long operations

### With CI/CD
- Reads logs from multiple CI providers (GitHub Actions, GitLab CI, Jenkins)
- Triggers new builds after fixes
- Monitors build status until completion

### With Git Workflow
- Respects branch protection rules
- Maintains clean commit history
- Handles complex merge scenarios

## Security Considerations

- **Repository isolation**: All operations in temporary directories
- **Permission validation**: Verifies write access before starting
- **Credential handling**: Secure authentication for git operations
- **Input validation**: Sanitizes all user inputs and external data
- **Cleanup guarantee**: Ensures temporary resources are always cleaned up

## Performance Optimizations

- **Parallel subagent execution**: Independent operations run concurrently
- **Cached reference materials**: O(1) access through parent-child model
- **Incremental progress**: Can resume from any major checkpoint
- **Smart error detection**: Identifies fix order to minimize iterations

## Monitoring and Observability

- **Detailed logging**: All operations logged with timestamps
- **Progress metrics**: Tracks time spent in each phase
- **Success rates**: Reports on fix success by error type
- **Performance data**: Measures subagent execution times
