yolo-verify

yolo-verify is a skill for Claude Code from CoriChui/yolo. It costs 62 tokens per session (447 once invoked), scanned A, original, MIT.

A verification workflow that checks completed feature work against its stated success criteria.

In plain words
What is it for?
Running the recorded lint and test commands, checking each success criterion, and writing a verification report.
Why use it?
It provides evidence for whether the feature is actually complete instead of relying on an informal 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

yolo-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 6d 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

yolo-verify

Decide, with evidence, whether the work satisfies the brief's success_criteria.

Inputs

  • workspace/features/<slug>/brief.md (success_criteria), the diff git diff <base_branch>...feature/<slug> (three-dot — only what the branch introduced; see .claude/yolo/conventions.md), and plan.md lint_commands/test_commands.

Procedure

  1. Run the recorded lint_commands and test_commands. Capture pass/fail and key output.
  2. For EACH criterion in success_criteria, gather concrete evidence (a passing test, an observed behavior, a code reference). Mark it met/unmet.
  3. Write workspace/features/<slug>/verification.md: one section per criterion with its evidence, plus the lint/test results.

Outcome

  • All criteria met → commit the verification file with the trailer: git add workspace/features/<slug>/verification.md && git commit -m "yolo: verify <slug>" --trailer "YOLO-Verified: true"
  • Any criterion unmet → write the file recording what failed, do NOT write the trailer, and report the gap so execution can resume. A feature is never "done" without YOLO-Verified: true (.claude/yolo/conventions.md). The execute→verify loop is bounded (.claude/yolo/conventions.md The two gates); after repeated failure the caller should stop and escalate to the human rather than re-running, since that signals the plan or criteria need rethinking.

Constraints

  • The only file you write is verification.md. You do not edit code.
  • Verification is semantic (criteria), distinct from CI (mechanical) — yolo-finish handles CI.
Changes

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.
