verification-before-completion

<skill_overview> Completion claims without fresh verification are not acceptable. Evidence first. </skill_overview>

<rigidity_level> LOW FREEDOM - No exceptions. Run the command, read the output, then make the claim. </rigidity_level>

<quick_reference> | Claim | Required evidence | |------|-------------------| | Tests pass | Fresh test output with no failures | | Build succeeds | Fresh build output with exit 0 | | Task slice complete | Updated tasks.md plus verification evidence | | Feature complete | Acceptance checks in plan.md satisfied with evidence |

Not sufficient: “should work”, “looks done”, or stale output. </quick_reference>

<when_to_use>

• Before any completion claim
• Before moving work to Done
• Before deleting a finished local task directory
• Before committing or opening a PR </when_to_use>

<the_process>

1. Identify the claim

What exact statement are you about to make?

2. Run the proof

Run the specific command or check that proves that claim.

3. Read the result

Confirm the output actually supports the claim.

4. Update the docs

If the work is complete:

• move the task to Done
• note the verification in context.md if it matters

5. Only then state completion

<examples> <example> <scenario>Developer says the slice is done because the code looks right</scenario>

<why_it_fails>

• No proof the behavior works
• No proof the spec was met </why_it_fails>

<correction> Run the relevant verification, update `tasks.md`, then claim completion with evidence. </correction> </example> </examples>
