Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00078 | $0.01752 |
| Opus 5 | $0.00039 | $0.00876 |
| Sonnet 5 | $0.00016 | $0.00350 |
| Haiku 4.5 | $0.00008 | $0.00175 |
Grade A, and why
codebase-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 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 — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codebase Audit → Issue → Worktree Fix → PR
End-to-end workflow: systematically review the entire codebase, report findings as GitHub issues, fix each issue in an isolated git worktree, and submit PRs — all in one session.
When to use this skill
Use this skill when you need to:
- Perform a full code review / audit of the codebase
- Proactively find security vulnerabilities, logic bugs, or code quality problems
- Turn code review findings into tracked GitHub issues
- Fix each issue in isolation (worktree per issue) and submit PRs
- Run a periodic codebase health check with automated follow-through
- Audit and fix dependency security vulnerabilities (Dependabot alerts / npm audit)
Do NOT use for:
- Reviewing or fixing a single known bug (use
systematic-debuggingor direct fix) - Triaging existing open PRs (use
pr-review-fix) - Processing attribution issues (use
mcp-attribution-worktree) - Feature development or refactoring unrelated to audit findings
Workflow
Phase 1 — Review
- Read
references/review-strategy.mdfor the review scope and checklist. - Use the
code-explorersubagent to read ALL source files in the target directory (default:mcp/src/). - For each file, systematically check against the review checklist:
- Security: path traversal, injection, unvalidated input, hardcoded secrets, improper error exposure
- Error handling: missing try-catch, swallowed errors, error messages leaking internals
- Type safety:
as any, unsafe casts, missing null checks - Logic bugs: race conditions, incorrect conditionals, unreachable code
- Code quality: dead code, duplication, overly complex functions
- Resource leaks: unclosed connections, missing cleanup
- API design: inconsistent validation, missing required field checks
- Record every finding with: file path, line number(s), category, severity (Critical/High/Medium/Low), description, and suggested fix.
- Dependency scan: Read
references/dependency-audit.mdand run the Dependabot alert fetch +npm auditto discover vulnerable dependencies. Record each finding using the dependency-audit format.
What ships with it
7 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.
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.

codebase-audit is a skill published in the GitHub repository TencentCloudBase/CloudBase-AI-Toolkit (1,087 stars, last pushed yesterday), licensed MIT. It adds 78 tokens to every session and 1,752 once invoked, about $0.0004 per session on Opus 5. 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.
