shipkit-prompt-audit

shipkit-prompt-audit is a skill for Claude Code, Codex from stefan-stepzero/shipkit. It costs 36 tokens per session (4,327 once invoked), scanned A, original, MIT.

A review skill for the engineering structure around AI model calls. It examines how prompts are split, connected, validated, parallelized, and recovered when something fails.

In plain words
What is it for?
Use it to review LLM integrations, prompt pipelines, AI features that are slow or unreliable, and systems being prepared for production.
Why use it?
It helps reveal problems that a normal prompt wording review will miss, such as slow chains, unsafe inputs, missing fallback paths, or unchecked model output.

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

shipkit-prompt-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.

shipkit-prompt-audit - LLM Prompt Architecture Audit

Purpose: Find structural problems in how your app talks to LLMs — monolithic prompts, missing fallbacks, sequential bottlenecks, unvalidated outputs, unsafe inputs.

What this is NOT: Not a prompt text quality checker. Not "make this prompt better." This audits the engineering architecture around prompts — how they're decomposed, chained, validated, and recovered from failure.


When to Invoke

  • /shipkit-prompt-audit — audit all LLM integrations
  • /shipkit-prompt-audit src/ai/ — focus on specific directory
  • "Audit my prompts", "Check prompt architecture", "LLM pipeline review"
  • "Are my AI calls structured well?"
  • "Check my prompts for anti-patterns"

Workflow position:

  • After implementing AI features, before shipping
  • When AI features feel slow or unreliable
  • During architecture review of LLM-heavy applications
  • When scaling from prototype to production AI

Prerequisites

Required:

  • Project has LLM integrations (API calls to OpenAI, Anthropic, Gemini, etc.)

Recommended:

  • .shipkit/stack.json — Knows which AI SDKs are in use
  • .shipkit/architecture.json — Knows pipeline design intent

If no LLM integrations found: Report cleanly and exit. Don't fabricate findings.


Process

Completion Tracking

After discovering integration points (Step 1), create tasks:

  • TaskCreate: "Map pipeline topology"
  • TaskCreate: "Audit all 10 dimensions (PA-DEC through PA-REF)"
  • TaskCreate: "Write prompt-audit.json (schema-validated)"
  • TaskCreate: "Present summary to user"

TaskUpdate each task to in_progress when starting it, completed when done.

If using parallel subagents for dimension auditing, verify ALL agent results are collected before synthesizing. Do NOT write the report until all 10 dimensions have findings (even if finding is "N/A").

Step 1: Discover LLM Integration Points

Scan the codebase for all LLM-related code using detection patterns.

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.

shipkit-prompt-audit is a skill published in the GitHub repository stefan-stepzero/shipkit (1 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 4,327 once invoked, about $0.0002 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 2026-08-31.
