audit-realworld

audit-realworld is a skill for Claude Code from kensaurus/cursor-kenji. It costs 58 tokens per session (3,182 once invoked), scanned A, original, MIT.

A read-only comparison of a full-stack application with RealWorld, also called Conduit, a standard demo specification and shared end-to-end test suite for a social blogging app.

In plain words
What is it for?
Use it to check API behavior, full-stack feature parity, and end-to-end flows against the RealWorld reference.
Why use it?
It turns “is the app complete?” into a check against a documented API and tests, while separating feature matching from production concerns such as security and deployment.

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

audit-realworld 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 1mo 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.

audit-realworld — Full-Stack Gap Audit vs the RealWorld Reference

Degree of freedom: MIXED — Mode, parity, and routing [HIGH freedom]; Phase 4 contract-suite run [LOW freedom — run exactly] when a server or suite exists.

Read-only. Findings and a prioritized gap report only — no code changes. Remediation goes to the skill named per finding.

RealWorld ("Conduit") is an objectively testable full-stack benchmark: formal API spec, shared E2E suite, shared CSS theme, hosted API at api.realworld.show.

The RealWorld API spec and its E2E suite are the source of truth — not any single community implementation. Reference repos vary; the spec and the passing suite do not.

RealWorld is a demo spec, not a production bar. It omits rate limiting, observability, caching, CI/CD, secrets, and deployment. Report feature/ pattern parity, then delegate hardening to audit-security, plan-security-audit, plan-perf-audit, plan-rls-audit, and full-stack-ship-discipline.

How to reason — Observe → Interpret → Classify → Severity

  1. Observe — quote the spec contract (or pattern) and the repo's file:line (or suite result)
  2. Interpret — does this layer implement the contract, or only the UI/route?
  3. Classify — Implemented / Partial / Missing / Diverges — or Bow-out if the repo is not a web CRUD+auth app
  4. Severity — core Conduit / authz / list-contract gaps = High; production-omitted concerns are routed, not scored as RealWorld misses

Worked example

Observe: Conformance mode. GET /api/articles returns { articles } with no articlesCount and no limit/offset (app/api/articles/route.ts). Bruno list request fails the count assertion. Auth header is Token <jwt>. Interpret: the list contract is partial; clients cannot paginate. Auth scheme matches the spec. Classify: Partial (pagination / articlesCount); auth Implemented. Severity: High — feed is a core Conduit surface. Finding: Article list | no pagination / articlesCount | High | complete-everything

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.
