audit-realworld

name	audit-realworld
description	Audit a full-stack app against the RealWorld ("Conduit") reference — its formal API spec, shared Bruno/Hurl E2E suite, and closest-stack reference implementation — to find what is implemented correctly, partially, or not at all across frontend, backend, and data layer. Auto-detects whether to run strict spec conformance (the repo IS a RealWorld build) or benchmark the repo's own domain against RealWorld's production-relevant patterns, and bows out cleanly on non-CRUD/non-web repos. Read-only: produces a prioritized gap report and hands remediation to other skills. Use when "audit against realworld", "compare my app to realworld", "conduit conformance", "is my full-stack app complete", "full-stack gap check", or "what's missing to reach production". RealWorld is a completeness/pattern reference, not a production bar — real hardening is delegated to audit-security / plan-* skills.

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

RealWorld ("Conduit", a Medium clone) is the most widely implemented full-stack benchmark: a formal API spec, a shared end-to-end contract test suite, a shared CSS theme, and a hosted API at api.realworld.show. That makes it objectively testable — unlike vague "best practice" references. This skill uses it to show, concretely, what your app has and hasn't built.

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

RealWorld is a demo spec, not a production bar. It deliberately omits rate limiting, observability, caching, CI/CD, secrets management, and deployment. This skill reports feature/pattern parity, then explicitly delegates real production hardening to audit-security, plan-security-audit, plan-perf-audit, plan-rls-audit, and full-stack-ship-discipline.

This is a read-only audit. It produces findings and a prioritized gap report; it does not change code. Remediation is handed to the skills named per finding.

Phase 0 — Detect the stack and gate applicability

Read the dependency manifest and source before comparing anything (reuse the audit-fe-api detection approach).

0a. Classify the stack

• Frontend: framework (React/Next/Vue/Nuxt/Svelte/Angular/Solid), router, state/data layer (TanStack Query, SWR, RTK, Pinia), HTTP client.
• Backend: framework (Express/Hono/Fastify/Nitro/NestJS/Django/Rails/Go/ Laravel/Spring), routing style, auth mechanism.
• Data layer: database + ORM/query builder (Prisma/Drizzle/TypeORM/Sequelize/ SQLAlchemy/ActiveRecord/Supabase), migration tool.
• Tests: unit runner, and any API/E2E harness (Bruno, Hurl, Postman/Newman, Playwright, Cypress).

0b. Applicability gate

Decide the mode — state which one and why, out loud:

Condition	Mode
Repo is a RealWorld/Conduit build (articles, profiles, favorites/follow, tags, JWT Token scheme)	Conformance
Web full-stack CRUD app with auth + owned resources, but a different domain	Benchmark
Not a web app, no HTTP API, no auth/resources (CLI, library, static site, pure ML)	Bow out

If you bow out, say so plainly and recommend the fitting skills instead (audit-security, audit-performance, plan-perf-audit, audit-code-quality, audit-fe-api). Do not force a RealWorld comparison onto a repo it does not fit.

0c. Record the discovery

STACK: FE=<...> · BE=<...> · DB/ORM=<...> · tests=<...>
MODE: Conformance | Benchmark | Bow-out (reason)
RealWorld reference chosen: <stack impl> (spec-compliant? maintained?)

---

Phase 1 — Pull the reference (current)

1a. Spec + test suite (source of truth)

• API spec and shared E2E suite live in the realworld-apps/realworld repo (specs/, Bruno .bru, Hurl .hurl) with a Postman collection for endpoint testing. The hosted API at api.realworld.show needs no keys.
• Fetch the current spec and note the exact endpoint/response/error contracts (summarized in Phase 2). Prefer the live spec over memory in case it has evolved.

1b. Closest-stack reference implementation

• Find the nearest implementation on codebase.show/projects/realworld, filter by the detected FE/BE stack. Prefer spec-compliant, recently maintained implementations (only a subset are verified spec-compliant at any time).
• Treat the reference as a pattern yardstick (folder structure, auth wiring, validation, error mapping) — not as gospel. When the reference and the spec disagree, the spec wins.

1c. Research current best practices

Follow the /research protocol for the detected stack (Context7 for library docs; Firecrawl for current patterns, dated to now). Anchor recommendations to the versions actually installed in the repo.

Phase 2 — Parity / pattern matrix

Conformance mode — audit against the RealWorld contract

Enumerate the spec surface and mark each Implemented / Partial / Missing / Diverges, with file:line evidence:

Auth & users

• POST /api/users (register), POST /api/users/login
• GET /api/user, PUT /api/user (current user)
• Auth header scheme: Authorization: Token <jwt> (not Bearer)

Profiles

• GET /api/profiles/:username
• POST / DELETE /api/profiles/:username/follow

Articles

• GET /api/articles (filters: tag, author, favorited, limit, offset)
• GET /api/articles/feed (auth, followed authors)
• GET / POST / PUT / DELETE /api/articles/:slug
• POST / DELETE /api/articles/:slug/favorite

Comments & tags

• GET / POST /api/articles/:slug/comments, DELETE .../comments/:id
• GET /api/tags

Cross-cutting contracts

• Response envelopes: { user }, { profile }, { article }, { articles, articlesCount }, { comment(s) }, { tags }
• Validation errors: 422 with { "errors": { "body": [ ... ] } }
• Auth failures: 401; missing resources: 404
• Pagination: limit / offset, with articlesCount for lists
• Slug generation, favoritesCount, following/favorited booleans reflect the requesting user

Benchmark mode — map the patterns onto the repo's own domain

The repo isn't Conduit, so audit whether it exhibits the same production- relevant patterns RealWorld demonstrates, for its own resources:

Pattern	What to check in this repo
Auth flow	Register/login/current-user; token issue + attach + refresh; protected routes
Owned resources + authz	CRUD on user-owned entities; ownership enforced server-side, not just UI
List semantics	Pagination, filtering, total counts, empty states
Relations	Follow/favorite-style join semantics done correctly (no N+1, correct counts)
Consistent envelopes	Uniform response + error shape across endpoints
Validation	Server-side validation with structured field errors
Contract tests	An API/E2E suite that proves the contract, not just unit tests

---

Phase 3 — Full-stack coverage sweep

Audit all three layers, not just whichever is easiest to read:

• Frontend: routes for each resource; auth flow (login/register/logout, token persistence, guarded routes); data layer (caching, error/loading/empty states); forms with validation and server-error surfacing.
• Backend: every spec/pattern endpoint present; auth middleware; input validation; consistent error mapping; pagination; correct status codes.
• Data layer: schema covers the entities and relations; migrations exist and are current; indexes on foreign keys and hot query paths; constraints (unique, not-null, FK) enforce integrity. Verify live via Supabase MCP when applicable.
• Tests: unit coverage on core logic, plus the RealWorld contract suite (or the repo's equivalent E2E harness).
• Build/config: app builds; env contract documented (names only).

---

Phase 4 — Live conformance test (optional but decisive)

If a server is running or the E2E suite is present, run the objective proof:

• Run the RealWorld Bruno collection (bru run), the Hurl files (hurl --test), or the Postman collection (newman run) against the local API base URL. Report pass/fail per endpoint.
• If no server is available, state exactly how to run it (base URL, seed/demo credentials) rather than guessing conformance from code alone.

A passing contract suite is stronger evidence than any static reading. Save any run artifacts under .playwright-mcp/ if using playwright-cli.

---

Phase 5 — Production layering (the honest part)

RealWorld parity is necessary breadth, not sufficient depth. Enumerate what RealWorld does not cover and route each to the right skill — do not imply parity means production-ready:

Concern RealWorld omits	Route to
AuthN/AuthZ hardening, secrets, injection, OWASP	audit-security, plan-security-audit
Row-level security / access control (Supabase)	plan-rls-audit
Performance, Core Web Vitals, query cost	plan-perf-audit, audit-performance, backend-db-performance
FE↔BE contract drift and runtime errors	audit-fe-api, debug-fe-be-integration
Rate limiting, observability, error handling	backend-observability, backend-error-handling
Deploy + migration/edge-function verification	full-stack-ship-discipline, deploy-verify

---

Phase 6 — Report (read-only)

## RealWorld Full-Stack Audit — [repo] — [date]

**Mode:** Conformance | Benchmark
**Stack:** FE [..] · BE [..] · DB/ORM [..] · tests [..]
**Reference:** [closest-stack impl] (spec-compliant: yes/no)
**Live contract suite:** ran (N/M passed) | not run — [how to run]

### Implemented correctly
- [feature/pattern] — [file:line]

### Partial (works but incomplete or diverges)
| Feature/Pattern | Gap | file:line | Severity | Fix via |
|---|---|---|---|---|
| Article feed | No pagination / articlesCount | ... | High | complete-everything |

### Missing
| Feature/Pattern | file:line (where it should live) | Severity | Fix via |
|---|---|---|---|
| DELETE comment authz | ... | High | workflow-fix-and-ship |

### Diverges from spec (Conformance mode)
| Endpoint | Spec says | Repo does | file:line |
|---|---|---|---|
| Auth header | `Token <jwt>` | `Bearer <jwt>` | ... |

### Production gaps (NOT covered by RealWorld — separate hardening)
- Security → `audit-security` · Perf → `plan-perf-audit` · RLS → `plan-rls-audit` · ...

### Recommended order
1. [Critical conformance/parity gaps] → complete-everything / workflow-fix-and-ship
2. [Production hardening] → audit-security → plan-perf-audit → ...

Forbidden: claiming production-readiness from RealWorld parity alone; inventing conformance without running or precisely describing the contract test; silently skipping a layer (FE, BE, or DB).
