CI Fixer

Diagnoses and fixes CI/CD pipeline failures.

When to Use

• "CI is failing"
• "Build broke"
• "Tests fail in CI but pass locally"
• "Pipeline error"
• "Deploy failed"

CI Workflows

Common Failures

1. TypeScript Errors

Symptom: tsc --noEmit fails

Diagnosis:

pnpm typecheck

Fixes:

• Add missing type annotations
• Fix type mismatches
• Update type imports

2. ESLint Errors

Symptom: eslint . fails

Diagnosis:

pnpm lint

Auto-fix:

pnpm eslint . --fix
pnpm format

3. Build Failures

Symptom: pnpm -C apps/web build fails

Common causes:

• Missing environment variables
• Import errors
• TypeScript errors not caught by tsc

Diagnosis:

pnpm -C apps/web build

4. Integration Test Failures

Symptom: pnpm test:integration fails

Common causes:

• Database not running
• Server not started
• Rate limiting (disable in CI)
• Missing test user

CI-specific:

• Uses GitHub Actions PostgreSQL service
• DISABLE_RATE_LIMIT=true
• ALLOW_DEV_TOKENS=true

5. Migration Failures

Symptom: migrate:apply fails in deploy

Common causes:

• Schema mismatch
• Missing migration file
• Database connection error

Diagnosis:

pnpm -C packages/db migrate:apply

6. Dependency Issues

Symptom: pnpm install fails

Fixes:

rm -rf node_modules pnpm-lock.yaml
pnpm install

Procedure

Step 1: Identify Failing Workflow

Check which workflow failed and what step.

Step 2: Read Workflow File

Read: .github/workflows/{workflow}.yml

Step 3: Reproduce Locally

Run the exact commands from the workflow:

# For ci.yml
pnpm install
pnpm tsc --noEmit
pnpm eslint .
pnpm -C apps/web build
pnpm -C packages/db migrate:apply
pnpm test:integration

Step 4: Check Environment

CI uses specific environment variables:

• DATABASE_URL - PostgreSQL connection
• DISABLE_RATE_LIMIT=true
• ALLOW_DEV_TOKENS=true

Step 5: Apply Fix

Based on diagnosis, apply appropriate fix.

Step 6: Verify

Run full CI check locally:

pnpm typecheck && pnpm lint && pnpm -C apps/web build

Environment Differences

Guardrails

• DO NOT modify workflow files without understanding impact
• DO NOT bypass failing checks without fixing root cause
• Always reproduce failure locally before fixing
• If fix is unclear, describe findings and ask for guidance
