# Verification Before Completion

## Custom Guide

Run: `bash "${CLAUDE_PLUGIN_ROOT}/lib/load-custom-guide.sh" cf-verification`

If output is not empty, integrate the returned sections into this workflow:

- `## Before` → execute before the first step
- `## Rules` → apply as additional rules throughout all steps
- `## After` → execute after the final step

## The Gate

**No completion claims without fresh verification evidence.**

Claiming work is complete without verification is dishonesty, not efficiency.

## When to Auto-Invoke

Auto-invoke this skill after tasks that **produce or modify code** (implementation, bug fixes, refactoring).

Do NOT auto-invoke after **analysis-only skills** that don't change code:

- `/cf-review` — code review is analysis, not implementation
- `/cf-plan` — planning doesn't produce code
- `/cf-ask` — Q&A doesn't produce code
- `/cf-research` — research doesn't produce code

## Checklist

Before claiming ANY task is done:

1. **Run tests** — Execute the test suite. Read the output. All tests must pass.
2. **Run the build** — If applicable, build the project. No errors.
3. **Lint/format** — If configured, run linter. No new warnings.
4. **Manual check** — For UI changes, verify visually. For API changes, test the endpoint.
5. **Show evidence** — Include test output, build output, or screenshots in your response.
6. **Slop check** — Scan changed code for AI transmarks, excessive comments, unnecessary verbosity.

## What Counts as Evidence

| Good Evidence                 | Bad Evidence                       |
| ----------------------------- | ---------------------------------- |
| Test output showing all pass  | "I believe the tests pass"         |
| Build output with exit code 0 | "The build should work"            |
| Actual command output         | "I ran the tests" (without output) |
| Screenshot of UI change       | "The UI looks correct"             |
| `git diff` showing the change | "I made the change"                |

## Common Failures

- [ ] Tests pass
- [ ] No type errors (TypeScript/typed languages)
- [ ] Linter clean
- [ ] Build succeeds
- [ ] No console errors/warnings
- [ ] Feature works as described
- [ ] No regressions in existing functionality
