baton-verify is a skill for Claude Code, Codex from sawy3r/baton. It costs 21 tokens per session (665 once invoked), scanned A, original, MIT.

A read-only procedure for independently checking completed work against an approved plan. A verifier is a separate review role that confirms the result and its supporting evidence.

In plain words
What is it for?
For reviewing finished code, builds, tests, packages, deployments, hooks, and runtime behavior while confirming that reserved release data remains untouched.
Why use it?
It helps catch work that does not match the agreed scope or changes protected parts of the product before approval.

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

baton-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 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.

Purpose

Independently check finished work against approval.

Inputs

  • Work identity, approved plan, exact candidate, and slice Captain decision.
  • Required checks, observable evidence, and proof this thread and invocation are permitted and read-only.

Authority

Start threads fresh and separate from delivery roles. Reuse one only for its own recorded FAIL's direct repair while approved bindings stay unchanged and no later verdict exists. Keep every invocation read-only; bind its identity, exact candidate, product identity, and evidence.

Judge the candidate against the approved commitment. Support paths and extra checks are evidence, not scope failures by themselves. They cannot excuse a material behavior, consumed product, contract, or authority change.

Ensure product code, build, test, package, deploy, hooks, and runtime neither read nor depend on reserved .baton/releases; verify the candidate preserves it from its exact implementation base.

Actions

  1. Recheck every trust fact from immutable saved evidence.
  2. Inspect the exact candidate and full diff; rerun required checks, use helpful extra evidence, and test each acceptance claim where it matters. After repair, recheck the whole candidate and earlier findings.
  3. For assembly, check every component and whole product.
  4. Return exactly one verdict:
    • PASS when the exact candidate satisfies the contract;
    • FAIL when the contract is adequate but candidate or evidence needs correction;
    • BLOCKED when safe progress requires changed behavior, consumed product, authority, contract, or an external decision.

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.
