auditor-skill: Instructions file for Codex

AGENTS.md

auditor-skill AGENTS.md is an instructions file for Codex, OpenCode from solanabr/auditor-skill. It costs 890 tokens per session, scanned A, original, MIT.

A set of instructions for coordinating a Solana and full-stack security audit. It describes specialist review stages, optional Rust pre-scanning, threat modeling, and checks for false positives.

In plain words
What is it for?
Use it to organize security-audit agents, reconstruct project context, model threats, find vulnerabilities, and coordinate audit reports.
Why use it?
It gives an agent a defined audit workflow so important review steps are not skipped or repeated unnecessarily.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; positional $N argument.

This is solanabr/auditor-skill's own configuration. It tells Codex and OpenCode how to work on auditor-skill itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything auditor-skill configures →

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

auditor-skill AGENTS.md 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.

auditor-skill — Agent Orchestration

This skill audits with a small team of subagents (see agents/) and, when available, orchestrates Trail of Bits execution tooling vendored at vendor/trailofbits.

Flow (full audit)

  1. Pre-scan (optional, deterministic). If tools/auditor-tools/ is built, audit-scan emits the instruction/constraint/PDA/arithmetic map at ~$0 and audit-mem warm <program-id> loads prior invariants + open false-positive rulings — seeding context-builder with a map instead of a blank repo, and letting vuln-hunter auto-suppress findings that carry a prior FALSE_POSITIVE ruling (audit-mem check). Falls back to the grep walk if the toolchain is absent. See references/orchestration/pre-scan.md.
  2. context-builder (sonnet) — Phase 0 setup + Phase 0.5 context reconstruction. No verdicts; understanding only. 1b. threat-modeler (opus) — from the context worksheets + audit_<n>/intake.md, emits audit_<n>/threat-model.md (asset inventory · actor×capability · trust boundaries) that hands the reviewers attacker goals and seeds report §4.4/§4.6/§4.7. No verdicts.
  3. vuln-hunter (opus) — item-by-item walk against in-scope checklists + phase-triggered vectors. Every finding with N ≥ 6 must pass the Rule 5b gate. Delegates SAST / harnesses to Trail of Bits when present (see references/orchestration/boundary-map.md).
  4. economic-analyst (opus) — checklist 06 + economic vectors; drives /economic-sim (Surfpool mainnet-fork) to quantify profitability for High/Critical economic findings.
  5. peer-reviewer (opus) — independent reconciliation on top-severity findings (N≥8, contested N≥7): re-derives from the code (reusing the context worksheets), delegates to Trail of Bits second-opinion/fp-check when present; emits CONFIRM / DISPUTE / DOWNGRADE. (Neodyme independent dual-review.)
  6. audit-reporter (sonnet) — deterministic assembly: Scope Coverage, findings, Phase 4.5 maturity scorecard, remediation roadmap → audit_<n>/REPORT.md.

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.
