project-audit

project-audit is a skill for Claude Code from Kin9Zeus/senior-engineer-skills. It costs 172 tokens per session (2,169 once invoked), scanned A, original, MIT.

A structured review of an existing codebase or product across engineering, security, operations, performance, accessibility, privacy, and documentation. It produces findings tied to specific code, routes, data, or configuration.

In plain words
What is it for?
Use it before launch, during due diligence, or when taking over a system to inspect architecture, APIs, testing, dependencies, deployment, observability, cost, SEO, privacy, and developer experience.
Why use it?
It turns broad concerns about a project into a prioritized list of problems with evidence and a way to verify each fix.

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

project-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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/recon.ps1, scripts/recon.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Audit

A real audit is evidence-driven. Every finding points at a line, a route, a table or a config key, and every finding carries a way to prove the fix. Opinions without locations are not findings.

Establish before reading code:

  1. What is in scope? Repository only, or also the live site, infrastructure and third-party accounts?
  2. What is the audit for? Pre-launch gate, investor due diligence, an inherited codebase, a security concern, or a general health check. This changes what gets weighted.
  3. What may be run? Read-only analysis is always safe. Ask before installing dependencies, running tests, starting services, or touching anything that reaches production.
  4. Is there a live URL? If yes, the web-presence-audit, accessibility-audit and privacy-compliance passes become live checks rather than code inference.

Never scan, probe or send traffic to infrastructure the user has not confirmed they own or are authorised to test.

State the scope in one line and begin.

Phase 1 — Ground truth

Run the discovery protocol from senior-engineer/references/discovery-protocol.md. scripts/recon.sh (or recon.ps1 on Windows) automates the first pass and prints a structured summary — run it if the environment allows, and fall back to the manual commands if not. It is read-only.

Do not proceed to findings until the Ground Truth block is filled in. An audit built on a misread stack is worse than no audit.

Phase 2 — The fifteen domain passes

Load the specialised skill for each domain rather than working from memory.

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.

project-audit is a skill published in the GitHub repository Kin9Zeus/senior-engineer-skills (3 stars, last pushed 2d ago), licensed MIT. It adds 172 tokens to every session and 2,169 once invoked, about $0.0007 per session on Opus 5.5. 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 2026-08-31.
