verification-and-release

verification-and-release is a skill for Claude Code, Codex from cmdr-chara/codex-toolkit. It costs 81 tokens per session (1,864 once invoked), scanned A, original, MIT.

A guide for checking whether a completed software change is safe to release. It bases the decision on tests, CI results, security, compatibility, monitoring, and rollback plans.

In plain words
What is it for?
Use it to create a verification plan, audit test and CI evidence, and decide whether a release is READY, CONDITIONAL, or BLOCKED.
Why use it?
It helps teams find missing proof before shipping and match the amount of checking to the change's risks.

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-and-release 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/summarize_test_reports.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verification and Release

Issue a release decision only from evidence proportional to consequence, novelty, and reversibility.

Trigger boundary

Use this skill for:

  • designing a verification plan from a diff, migration, or release candidate;
  • auditing CI/test evidence and identifying material gaps;
  • deciding READY, CONDITIONAL, or BLOCKED for a release;
  • defining rollout, monitoring, rollback, and post-release checks.

Do not trigger for:

  • implementing product behavior or writing the initial feature tests;
  • investigating why a test or production symptom fails—use debugging-investigator;
  • executing an upgrade—use codebase-evolution-controller;
  • reviewing a tiny local edit when no release decision or broader evidence strategy is requested.

Required inputs

Collect or explicitly mark unavailable:

  1. integrated diff or release candidate identifier and repository state;
  2. intended behavior, acceptance criteria, and affected users/consumers;
  3. architecture/change-impact evidence and risk-sensitive surfaces;
  4. CI runs, local checks, coverage or test map, and known baseline failures;
  5. deployment topology, feature flags, migrations, observability, and rollback mechanism;
  6. security, privacy, compliance, platform, and compatibility constraints;
  7. release scope, cohort, timing, and responsible owner.

A list of commands without the exact artifact/ref and result is not release evidence.

Safety baseline

  • Inspect current worktree and candidate identity before running checks.
  • Do not discard, clean, stash, rewrite, or auto-fix user work.
  • Do not mark a check passed when it was skipped, filtered, flaky, retried to green without analysis, or run against a different revision.
  • Do not expose secrets in logs, screenshots, or evidence bundles.
  • Do not perform production deployment or rollback merely because this skill recommends it; use the project's authorized release mechanism and owner.
  • Treat irreversible schema/data changes as release blockers until restore or forward-recovery evidence exists.

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.
