d-o-hub Self-Fix Loop
Automated CI failure remediation with iterative repair attempts.
When to Use
- After a push that triggers CI failure
- When error type is known and fixable programmatically
- For repeatable, deterministic error patterns
Do NOT Use
- When error requires architectural decisions
- When fix needs user input or clarification
- When max iterations reached without resolution
Process
┌─────────────────────────────────────────────────┐
│ 1. DETECT: Fetch CI logs, identify failure │
│ 2. CLASSIFY: Categorize error type │
│ 3. FIX: Apply appropriate remediation │
│ 4. RETRY: Push fix, re-run CI │
│ 5. REPEAT until PASS or MAX_ITERATIONS (5) │

Error Classification & Remediation
| Error Type | Detection Pattern | Fix Strategy |
|---|---|---|
| shellcheck | shellcheck: SC\d+ |
Apply suggested fix, quote variables |
| YAML | yaml: line \d+: |
Fix indentation, syntax |
| lint/clippy | error\[E\d+\] or clippy:: |
Address specific lint warning |
| security | security:, vulnerability |
Update dependency, patch CVE |
| test | test failed, assertion |
Debug failing test, fix logic |
| build | cannot find, unresolved |
Fix imports, add dependencies |
Loop Parameters
| Parameter | Default | Description |
|---|---|---|
MAX_ITERATIONS |
5 | Maximum fix attempts before escalation |
COOLDOWN |
30s | Wait between CI check polls |
TIMEOUT |
10m | Max time per iteration |
Step-by-Step Execution
1. Detect Failure
gh run list --limit 1 --json conclusion,status,databaseId
gh run view <run-id> --log-failed
2. Classify Error
Parse logs for known patterns. Map to fix strategy.
3. Apply Fix
Execute appropriate remediation based on classification:
- shellcheck:
shellcheck -f diff script.sh | git apply - clippy: Address specific warnings with code changes
- test: Analyze failure, modify test or code
4. Retry
git add -A
git commit -m "fix: automated remediation for <error-type>"
git push
5. Monitor
gh run watch --exit-status
Escalation Criteria
Stop the loop and escalate when:
- Iteration count exceeds
MAX_ITERATIONS - Error type is unclassifiable
- Fix requires architectural change
- Multiple unrelated failures detected
Example Usage
User: "The CI is failing, fix it automatically"
Agent: [Self-Fix Loop activated]
1. Detected: clippy error `unused_variable`
2. Classified: lint warning
3. Fixed: Prefixed with `_` to suppress
4. Retried: Push, CI passes
5. Result: PASS after 1 iteration
Safety Constraints
- Never force-push to main/master
- Never skip CI with
--no-verify - Always create new commits (never amend existing)
- Preserve commit message style from repository
