audit-verify

audit-verify is a skill for Claude Code, Codex from Snowflake-Labs/cocoplus. It costs 18 tokens per session (342 once invoked), scanned A, original, MIT.

A tool that checks whether local CocoPlus audit records are complete, correctly ordered, and linked by their hashes when hashes exist. With full checking, it also tests whether contract proof can still be reproduced from committed inputs.

In plain words
What is it for?
Use it to verify audit history and contract evidence before review or compliance checks.
Why use it?
It finds missing records, altered history, broken links, and proof drift without silently repairing the evidence.

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

audit-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 1mo 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

Your objective is to implement $audit verify [--full].

Before proceeding, verify that .cocoplus/ exists. If not, output: "CocoPlus not initialized in this directory. Run $pod init to begin." Then stop.

Contract

Read .cocoplus/audit/, lifecycle audit records, and contract proof artifacts. Validate append-only ordering, required fields, timestamp presence, actor/source provenance, and hash-chain continuity when hashes are present.

With --full, also re-check CocoContract proof artifacts and report whether archived falsifiability checks remain reproducible from committed inputs.

Output:

  • Verified artifact count
  • Broken or missing links
  • Contract proof status
  • Highest-severity finding
  • Recommended next command

Exit Criteria

  • Missing audit artifacts produce an explicit "no audit artifacts found" result.
  • Hash or ordering failures are reported as deterministic audit failures.
  • Contract proof drift is distinguished from missing proof.
  • The command never repairs audit history silently.

Anti-Rationalization

Shortcut / Temptation Why It Fails
Treat the skill as complete because the file exists Skill contracts must describe observable behavior and verification, not just command names.
Skip artifact and safety checks for a small command Small commands still mutate state or guide execution; preserve the same gates.
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.

audit-verify is a skill published in the GitHub repository Snowflake-Labs/cocoplus (729 stars, last pushed 6d ago), licensed MIT. It adds 18 tokens to every session and 342 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
