verification-before-completion is a skill for Claude Code from Vimalk0703/shipworthy. It costs 29 tokens per session (383 once invoked), scanned A, original, MIT.

A completion rule requiring fresh test, build, or lint results before claiming that a coding task is finished. It checks the full command output and makes sure the claim matches the evidence.

In plain words
What is it for?
It is for choosing the right proof command, running it, reading its results, and reporting exactly what passed or failed.
Why use it?
It prevents broken changes from being described as complete based only on assumptions or a quick visual review.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

verification-before-completion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Verification Before Completion

The Iron Rule

NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE.

The 5-Step Gate

Step 1: Identify the Proof Command

What command proves this works?

  • npm test / pytest / go test ./...
  • npm run build / tsc --noEmit
  • npm run lint
  • A specific test file: npx vitest run src/services/user.test.ts

Step 2: Run It

Execute the command. Do not skip this step.

Step 3: Read the Output

Read the FULL output — not just "it passed." Look for warnings, skipped tests, deprecation notices.

Step 4: Verify Your Claim Matches Reality

Does the output actually prove what you're about to claim? "All 47 tests pass" is verifiable. "It should work correctly" is not.

Step 5: Assert with Evidence

Now claim completion, citing evidence:

  • "All 47 tests pass (including 3 new tests for the user service)"
  • "Build completes with 0 errors and 0 warnings"

Red Flag Language

If you catch yourself about to say any of these, STOP — you haven't verified:

  • "should work"
  • "probably fine"
  • "I believe this is correct"
  • "this looks right"
  • "I'm confident that..."
  • "based on my understanding..."

Replace with: "Let me verify." Then run the command.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
