cy-final-verify

cy-final-verify is a skill for Claude Code, Codex from compozy/skeeper. It costs 66 tokens per session (1,602 once invoked), scanned A, a copy of cy-final-verify, MIT.

A verification workflow for checking work before calling it complete, committing it, or creating a pull request. It requires fresh evidence from the relevant project checks.

In plain words
What is it for?
Use it before reporting success, handing work over, committing code, or opening a pull request to identify the command, run it, read its result, and confirm what it proves.
Why use it?
It prevents completion claims based only on inspection or old results. The required checks are matched to the size of the claim, from one test to the full project pipeline.

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

cy-final-verify 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 4d 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.

Verification Before Completion

Overview

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

Core principle: Evidence before claims, always.

Violating the letter of this rule is violating the spirit of this rule.

The Iron Law

NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE

If the verification command has not been run in the current message, the result cannot be claimed.

The Gate Function

BEFORE claiming any status or expressing satisfaction:

1. IDENTIFY: What command proves this claim?
2. RUN: Execute the FULL command (fresh, complete)
3. READ: Full output, check exit code, count failures
4. VERIFY: Does output confirm the claim?
   - If NO: State actual status with evidence
   - If YES: State claim WITH evidence
5. ONLY THEN: Make the claim

Skip any step = lying, not verifying

Scope of Verification

Match the verification scope to the claim scope:

  • Narrow claim (e.g., "this test passes"): Run the specific test.
  • Broad claim (e.g., "task complete", "ready to commit"): Run the full verification pipeline — formatting, linting, all tests, and build. If the project defines a single gate command (e.g., make verify), run that.

A narrow verification does not support a broad claim. Running make test alone does not justify "task complete." Running the linter alone does not justify "ready to commit." The verification scope must be equal to or broader than the claim scope.

If in doubt, run the full pipeline. Over-verification wastes minutes. Under-verification wastes hours.

Passing pipeline != meeting requirements. A green build proves the code compiles, lints, and passes existing tests. It does not prove the implementation matches the requirements. For "task complete" or "requirements met" claims, also verify the deliverables against the original specification — line by line, not by assumption.

Common Failures

Claim Requires Not Sufficient
Tests pass Test command output: 0 failures Previous run, "should pass"
Linter clean Linter output: 0 errors Partial check, extrapolation
Build succeeds Build command: exit 0 Linter passing, logs look good
Bug fixed Test original symptom: passes Code changed, assumed fixed
Regression test works Red-green cycle verified Test passes once
Agent completed VCS diff shows changes Agent reports "success"
Requirements met Line-by-line checklist Tests passing

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.
