quaere-audit

quaere-audit is a skill for Claude Code, Codex from haru0416-dev/quaere. It costs 146 tokens per session (4,132 once invoked), scanned A, original, MIT.

A structured process for reviewing software for security weaknesses. It checks whether an attacker can reach a vulnerable operation, bypass a required protection, and cause a specific impact before treating something as a confirmed finding.

In plain words
What is it for?
Use it for vulnerability reviews, bug-bounty triage, threat modeling, authentication and authorization checks, tenant isolation, injection risks, protocol conformance, or security-sensitive pull requests.
Why use it?
It helps separate real, exploitable security problems from suspicious code patterns or outdated warnings. This reduces false positives during security reviews.

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

quaere-audit 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.

Security Audit Loop

Iron Law

No security finding is confirmed without a falsifiable property, a reachable attacker-controlled path, a missing or failed guard, concrete impact, and a disconfirming false-positive pass.

This is the security version of evidence-gating. Dangerous APIs, scary strings, stale advisories, and pattern matches are leads, not findings. A finding becomes actionable only when the audit can show why the property should hold, where an attacker crosses a boundary, which sink/state/guard fails, what impact follows under the threat model, and what counter-evidence was checked. If any link is missing, classify it as potential, rejected, or inconclusive.

When to use

  • Vulnerability discovery, security code review, bug bounty preparation, exploitability triage, or protocol/spec-grounded auditing.
  • Auth/authz, tenant isolation, injection, parser, sandbox, cryptography, consensus, payments, secrets, SSRF, deserialization, supply-chain, cloud/config, or CI/CD security work.
  • Security-sensitive PRs or incidents where false positives, unsafe probes, or stale external facts would be costly.

When NOT to use

  • Pure dependency lookup or CVE freshness checks with no local exploitability analysis; use quaere-grounding first.
  • Normal implementation after a vulnerability is already confirmed and a fix is authorized; use quaere-execution.
  • General maintainability review, one-line known fixes, or shallow checklist-only reviews.
  • Any task whose rules of engagement are missing and probing could affect third-party or production systems; stop and ask.

Handoff triggers (which skill comes after this one)

Audit coordinates other skills; hand off when the blocking question is not security-property mapping:

  • Code intent, invariants, failure modes, or downstream connections are unclear → quaere-semantic.
  • Current specs / CVEs / advisories / docs / cloud behavior / framework guidance / CLI behavior / bounty rules must be anchored → quaere-grounding.
  • A subtle / disputed / security-sensitive candidate finding still needs proof before being confirmed → quaere-evidence.
  • Safe PoC, regression test, or authorized fix is the next step → quaere-execution.

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.
