PR Fix Skill

Create pull requests and interactively fix CI check failures until all pass.

Quick Start

# Create PR from current changes
/sc:pr-fix "fix: resolve test failures" --branch fix/tests

# Dry run to preview
/sc:pr-fix "feat: new feature" --dry-run

# With custom PR details
/sc:pr-fix "chore: update deps" --title "Update dependencies" --body "Monthly update"

# Auto-fix low-risk issues
/sc:pr-fix "fix: lint errors" --auto-fix

Behavioral Flow

1. Validate - Check git state, ensure changes exist
2. Branch - Create and checkout new branch
3. Commit - Stage all changes and commit with provided message
4. Push - Push branch to origin
5. PR Create - Create pull request via gh CLI
6. Monitor - Poll CI status at configured interval
7. Fix Loop - For each failing check:
   • Parse failure logs
   • Propose fix (with PAL MCP assistance for complex issues)
   • Prompt user for confirmation (interactive mode)
   • Apply fix and push
   • Re-monitor checks
8. Complete - All checks pass or max attempts reached

Flags

Interactive Mode

By default, the skill prompts before each fix:

================================================================================
CI Check Failed: build (lint)                                   Attempt 2 of 5
================================================================================

Error Summary:
  - src/component.ts:42:15 - Missing semicolon (semi)
  - src/utils.ts:18:1 - Unexpected console statement (no-console)

Proposed Fix:
  1. Add semicolon at src/component.ts:42
  2. Remove console.log at src/utils.ts:18

Risk Level: LOW (auto-fixable lint errors)

--------------------------------------------------------------------------------
[A]pply fix  [S]kip this check  [V]iew full log  [Q]uit
>

Use --auto-fix to skip prompts for low-risk fixes (lint, formatting). High-risk fixes (test changes, security, core logic) always prompt.

Risk Classification

Evidence Requirements

This skill requires evidence of successful operations:

• Git operations must succeed (branch created, pushed)
• PR creation must return valid PR URL
• CI status must be retrievable via gh CLI
• Fix attempts must show file diffs

Tool Coordination

• Bash - Git and gh CLI execution
• Read - Analyze failure logs and source code
• Edit - Apply fixes to source files
• AskUserQuestion - Interactive prompts for fix confirmation
• PAL MCP debug - Diagnose complex CI failures
• PAL MCP codereview - Validate fix quality before applying

MCP Integration

• PAL MCP debug - Root cause analysis for CI failures
• PAL MCP codereview - Review proposed fixes before applying

Safety Mechanisms

1. Hard cap: Maximum 5 fix iterations (cannot be overridden)
2. Stagnation detection: Same error 3 consecutive times = abort
3. Oscillation detection: Fix-revert-fix pattern = abort
4. Interactive confirmation: All structural changes require approval
5. Never skip checks: Must fix or explicitly abort - no skipping
6. Backup branch: Creates backup/<branch>-<timestamp> before starting

CI Status Polling

The skill polls GitHub Actions check status using:

gh pr checks <pr_number> --json name,state,conclusion,url

Poll behavior:

• Initial wait: 10 seconds after push (allow CI to start)
• Poll interval: --poll-interval seconds (default: 30)
• Timeout: 10 minutes for checks to complete
• Handles pending, queued, in_progress, and completed states

Failure Log Parsing

Supported CI output formats:

• ESLint/TSLint JSON format
• pytest output with tracebacks
• ruff/flake8 format
• Jest/Vitest output format
• Generic error patterns (error:, ERROR, failed)
• GitHub Actions annotations

Examples

Basic PR Creation with Fix Loop

/sc:pr-fix "fix: resolve ESLint errors"

Output:

Creating branch: pr-fix/20240115-143022
Committing: fix: resolve ESLint errors
Pushing to origin...
Creating PR #42: fix: resolve ESLint errors

Monitoring CI checks...
  - lint: pending
  - test: pending

[30s later]
  - lint: failed
  - test: passed

Parsing lint failures...
Found 2 errors in 1 file.

================================================================================
CI Check Failed: lint                                           Attempt 1 of 5
================================================================================

Feature PR with Details

/sc:pr-fix "feat: add user dashboard" \
  --branch feat/user-dashboard \
  --title "Add User Dashboard Component" \
  --body "Implements user dashboard as per spec #42"

Preview Mode

/sc:pr-fix "refactor: cleanup utils" --dry-run

Output:

[DRY RUN] Would execute:
  1. git checkout -b pr-fix/20240115-143022
  2. git add -A
  3. git commit -m "refactor: cleanup utils"
  4. git push -u origin pr-fix/20240115-143022
  5. gh pr create --base main --title "refactor: cleanup utils"
  6. Monitor CI and fix failures interactively

No changes made.

Auto-Fix Low-Risk Issues

/sc:pr-fix "fix: formatting" --auto-fix

With --auto-fix, LOW risk fixes (lint, formatting) are applied automatically. MEDIUM and HIGH risk fixes still prompt for confirmation.

Termination Conditions

The fix loop terminates when:

Commit Message Format

Fix commits follow Conventional Commits:

fix(ci): resolve <check_name> failures

- <description of fix 1>
- <description of fix 2>

Automated fix by sc-pr-fix skill

Scripts

This skill uses Python helper scripts in scripts/:

• check_pr_status.py - Poll PR check status via gh pr checks
• parse_check_failures.py - Parse CI failure logs to extract errors
• fix_orchestrator.py - Coordinate fix loop with safety mechanisms
