security-audit

security-audit is a skill for Claude Code, Codex from abuango/pos-ai. It costs 48 tokens per session (815 once invoked), scanned A, original, MIT.

A procedure for reviewing a codebase for security weaknesses using the OWASP Top 10, a common list of web-application security risks. It covers access control, encryption, injection, authentication, dependencies, and related areas.

In plain words
What is it for?
Use it to identify the target project, review its technology and sensitive areas, check common vulnerability patterns, and write a dated security-audit report.
Why use it?
It provides a repeatable security review process instead of relying on an ad hoc inspection. It also specifies where to record findings and which project context to check first.

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-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 5d 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

Setup

Before starting: check .handoff/sessions/ for active sessions, read context status.yaml, run git status. Follow .rules/universal.md (Plan -> Approve -> Execute).

Perform security audits following OWASP Top 10 methodology.

Process

  1. Identify Target

    • Get workspace path from project.yaml
    • Understand technology stack
    • Identify sensitive areas (auth, payments, data)
  2. Systematic Review

  3. Document Findings

    • Save to: teams/{team}/projects/{project}/reviews/security-audit-{date}.md

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
