release-checker

release-checker is a skill for Claude Code from beingmartinbmc/jambavan. It costs 48 tokens per session (648 once invoked), scanned A, original, MIT.

A verification procedure for checking claims about tests, builds, bug fixes, requirements, or release readiness. It requires fresh evidence from the current code before reporting success.

In plain words
What is it for?
Choosing the right check, running it, reading its full result, and reporting whether the requested work is actually verified.
Why use it?
It prevents an agent from claiming that work is complete based only on assumptions or old results.

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

release-checker 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Release Checker

If the verify_gate MCP tool is available, call it with your claim (and type: tests/build/fix/requirements/general) and use its output as a verification checklist. Otherwise, follow the protocol below directly.

Evidence rule

Match each completion claim to fresh evidence from the current working tree. If a relevant check is unavailable, unsafe, or disproportionate, report that limitation instead of presenting the result as verified.

The Gate

Before making a success or completion claim:

  1. IDENTIFY: What command proves this claim?
  2. RUN: Execute the smallest complete command appropriate to the risk.
  3. READ: Inspect the complete result, including exit code and failure count.
  4. VERIFY: Does output confirm the claim?
    • YES → State the claim with concise evidence.
    • NO → State the actual status and the relevant failure.

Do not imply that an unrun check passed.

Verification by claim type

Tests — Run the relevant test command and report its pass/fail summary. Claim the full suite passes only after running the full suite; a focused test proves only its own scope.

Build — Run the build command. Check exit code. "Build succeeds" requires build output showing exit 0. Linter passing ≠ build passing. Type-check passing ≠ bundle succeeding.

Bug fix — Prefer a reproducer that fails before the fix and passes after it. When a safe pre-fix run is impractical, explain the alternative evidence. Run regression checks in proportion to the change's blast radius.

Requirements met — Re-read the original requirements/plan. Create a line-by-line checklist. For each item: what proves it's done (test? output? demo?). Check each item with evidence. Report gaps honestly — "tests pass" ≠ "requirements met."

Release / PR ready — Apply the relevant checks above, inspect the final diff for scope and debug artifacts, and distinguish intended uncommitted work from unrelated user changes.

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.

release-checker is a skill published in the GitHub repository beingmartinbmc/jambavan (2 stars, last pushed 5d ago), licensed MIT. It adds 48 tokens to every session and 648 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
