Self-Fix Loop Skill

When to Use

Automated self-learning cycle: commit → push → monitor → analyze failures → fix → retry until all CI checks pass.

Self-Fix Threshold: If 2+ similar errors occur during the loop, pause and diagnose the root cause before attempting another fix.

Overview

Continuous improvement loop that:

1. Commits all changes atomically
2. Pushes to feature branch
3. Creates/updates PR/MR
4. Monitors CI (GitHub Actions or GitLab CI)
5. On failure: diagnoses and fixes
6. Repeats until ALL checks pass

Platform Detection

Auto-detect from git remote:

REMOTE=$(git remote get-url origin)
if echo "$REMOTE" | grep -qi "github"; then
  PLATFORM="github"; CLI="gh"
elif echo "$REMOTE" | grep -qi "gitlab"; then
  PLATFORM="gitlab"; CLI="glab"
fi

Arguments

Loop Phases

[Start]
   ↓
Phase 1: COMMIT & PUSH
   - Stage all changes
   - Run quality gate
   - Atomic commit
   - Push to feature branch
   ↓
Phase 2: CREATE/UPDATE PR/MR
   - Create new PR/MR or update existing
   ↓
Phase 3: MONITOR CI
   - Poll GitHub Actions / GitLab CI
   - Wait for all checks complete
   ↓
Phase 4: ANALYZE FAILURES
   - Identify failed checks
   - Extract error messages
   - Categorize failure type
   ↓
Phase 5: FIX (if failures)
   - Diagnose root cause
   - Apply fixes
   - Commit fix
   ↓
Phase 6: RETRY LOOP
   - If retries remaining → Phase 1
   - If max retries → FAIL
   - If all pass → SUCCESS

Rust Failure Types

Stacked PR Interaction

If the current branch is part of a gh stack (check: gh stack view --json 2>/dev/null succeeds):

1. Commit fixes as NEW commits — never amend stacked commits
2. Run gh stack rebase --upstack to propagate changes to dependent branches
3. Run gh stack push to update all dependent PRs

Do NOT use git push --force on stacked branches — use gh stack push instead. Do NOT use git commit --amend — it breaks upstack branch ancestry.

Rationalizations

Red Flags

• Exceeding max retries without diagnosing root cause
• Disabling strict validation to bypass failing checks
• Force merging when the self-fix loop reports failure
• Using git commit --amend or git push --force on stacked branches (use gh stack push instead)
