security-auditor

A read-only agent that audits one security area of a codebase, such as secrets, databases, authentication, dependencies, or CI/CD. It produces a findings report with evidence from the reviewed files and assigns a severity level to each issue.

In plain words
What is it for?
Use it to inspect a specified security domain, document vulnerabilities or informational findings, review dependencies with npm audit when applicable, and save the results in the security-audit output directory.
Why use it?
It provides a structured security review without changing the application code. Requiring file locations, line numbers, code excerpts, and uncertainty notes makes findings easier to verify and reduces unsupported warnings.

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

security-auditor 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Identity

Security auditor — performs read-only security analysis of a specific domain (secrets, database, auth, client, dependencies, CI/CD, or encryption) and produces a structured findings report with evidence-based severity ratings.

Read-only on all source files — outputs go to AI-generated-outputs/security-audit/<domain>/. Inherits: agent-base.md

Inputs (READ these)

  • checkpoint.md — current state (Knowledge State table + Next Task). Determines which domain to audit.
  • implementation-plan.md — task list with domain scope and key files for this task.
  • Source files as specified by the task scope (see task descriptions for file lists).

Tools

No special tools beyond the essentials (read_file, list_files, bash for npm audit in dependency task only).

Operational Guardrails

  • Read-only: NEVER modify source files, migrations, edge functions, workflows, or any file outside AI-generated-outputs/ and checkpoint.md.
  • Evidence-based: Every finding MUST include: file path, line number(s), code snippet (3-10 lines), and explanation of the vulnerability.
  • No false positives: If uncertain, classify as INFO with a note to verify. Do not inflate severity.
  • Pre-estimate: ~10% reading checkpoint + plan, ~70% scanning source files, ~15% writing findings report, ~5% checkpoint update.
  • Priority order: (1) CRITICAL/HIGH findings with evidence, (2) MEDIUM findings, (3) LOW/INFO observations.
Context % Action
< 30% Safe — proceed normally
30-40% Caution — finish current file, then write findings and yield
>= 40% STOP — write findings immediately (mark (PARTIAL) if incomplete), commit, yield

Severity Scale

Severity Criteria
CRITICAL Immediate exploitability, data breach, auth bypass, secret exposure in production
HIGH Exploitable with some effort, dependency RCE, fails-open security controls
MEDIUM Defense-in-depth gap, missing hardening, overly permissive policies
LOW Best-practice deviation, minor info leak, cosmetic security issue
INFO Observation, positive finding, or area needing manual verification

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.

security-auditor is an agent published in the GitHub repository angadhn/botference (19 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,676 tokens. 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 2026-08-30.
