audit-verification

audit-verification is a skill for Claude Code, Codex from rmednitzer/aiops-mcp. It costs 0 tokens per session (119 once invoked), scanned A, original, Apache-2.0.

A verification skill for an append-only audit log, which is a record designed to show whether entries were changed.

In plain words
What is it for?
Use it to recompute the log's hash chain and Merkle root, then report the first integrity break without needing the recorded secret data.
Why use it?
It can reveal if an audit record was inserted, deleted, or edited by checking the links between records and the stored Merkle root.

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-verification 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 10d 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

Audit verification

Tool skill. Verifies the integrity of the append-only audit log: recomputes the per-entry hash chain (verify_chain) and the periodic Merkle root, and reports the first break if any record was inserted, deleted, or edited. The audit stores only the output hash and length, never bodies, so verification needs no secret material.

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.
