description	Create PR and iteratively fix CI failures with interactive confirmation. Automates branch creation, commit, push, PR creation, and CI monitoring until all checks pass.

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

Flag	Type	Default	Description
--branch	string	auto	New branch name (auto: pr-fix/<timestamp>)
--base	string	main	Target branch for PR
--title	string	commit msg	PR title
--body	string	auto	PR description body
--dry-run	bool	false	Preview operations without executing
--auto-fix	bool	false	Auto-apply low-risk fixes, prompt only for high-risk
--max-fix-attempts	int	5	Max CI fix iterations (hard cap: 5)
--poll-interval	int	30	Seconds between CI status checks
--no-push	bool	false	Create branch and commit but do not push/PR

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

Level	Examples	Behavior
LOW	Lint errors, formatting, whitespace	Auto-fix if --auto-fix
MEDIUM	Test updates, documentation	Always prompt
HIGH	Core logic, security, API changes	Always prompt + PAL review

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:

Condition	Exit Status	Message
All checks pass	SUCCESS	"All checks passed! PR ready for review."
Max attempts (5)	FAILED	"Max fix attempts reached. Manual intervention required."
Stagnation (3x same error)	FAILED	"Same error persists after 3 attempts. Aborting."
User quits	ABORTED	"Fix loop aborted by user."
CI timeout	TIMEOUT	"CI checks did not complete within timeout."

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

Error Handling

Scenario	Behavior
No git repo	Exit with error message
Dirty working tree	Prompt: stash, commit, or abort
Branch already exists	Prompt for different name
Push fails	Check permissions, offer retry
PR creation fails	Show gh CLI error, suggest manual
CI timeout	Report status, offer to continue monitoring
Parse failure	Fall back to raw log display
Fix application fails	Increment attempt counter, continue loop
User aborts	Clean exit with status summary
