Mvp Readiness

MVP Readiness Audit

Run a structured quality-gate audit before declaring any project an MVP. Check every item. Report pass/fail with evidence. Flag blockers.

Instructions

Two modes:

• Full audit (default /mvp-readiness): complete checklist across all 8 sections. Use before launch.
• Quick scan (/mvp-readiness --quick): checks only the 5 hard blockers. Completes in under 30 seconds. Use during daily development.

If --quick is passed, skip to the Quick Scan section and stop after producing the quick scan output. Do not run the full checklist.

Quick Scan

Run each of the following 5 checks using Bash or Grep — do not read files individually. Report results in the compact output format below.

Check 1 — Secret Scan

grep -rn "password\s*=\s*['\"]" --include="*.js" --include="*.ts" --include="*.py" --exclude-dir=node_modules .

Adapt the file extensions for the detected language. FAIL if any match is found outside of test files (*.test.*, *.spec.*, tests/, __tests__/).

Check 2 — README Exists

Check that README.md or readme.md exists and is greater than 100 bytes. FAIL if the file is missing or empty.

Check 3 — External Call Error Handling

grep -rn "fetch(\|axios\.\|\.query(\|\.connect(" --include="*.js" --include="*.ts" . | grep -v "try\|catch\|then\|rescue"

This is a rough heuristic. FAIL if more than 5 uncovered calls are found.

Check 4 — No Secrets in Git History

git log --all --oneline -- "*.env" 2>/dev/null | head -5

FAIL if any .env files appear in the git history.

Check 5 — Placeholder Code

grep -rn "TODO\|FIXME\|stub\|placeholder\|impl later" --include="*.js" --include="*.ts" --include="*.py" --exclude-dir=node_modules . | grep -v "test\|spec"

FAIL if any results are found in non-test files.

Quick Scan Output Format

Produce a compact result in this exact format:

## MVP Quick Scan — <project> — <date>

✓ Secret scan: PASSED
✗ README: FAILED — README.md not found
✓ Error handling: PASSED (heuristic)
✓ Git history: PASSED
⚠ Placeholder code: WARNING — 3 TODOs in src/ (non-blocking)

Status: NOT READY — 1 blocker. Run /mvp-readiness for full audit.

Use ✓ for PASSED, ✗ for FAILED (blocker), and ⚠ for WARNING (non-blocking). The status line must say READY only if all 5 checks pass.

Full Audit

Run all steps below, then evaluate every item in the MVP Checklist.

1. Use Read to load README.md and any files found in docs/.

2. Use Glob to discover the project structure:

   • Source files: src/**/*, lib/**/*, app/**/* (adapt to the project layout)
   • Config files: package.json, pyproject.toml, go.mod, .env.example, .gitignore
   • Entry points: index.*, main.*, server.*, app.*

3. Use Grep to check for common problems across the codebase:

   • Hardcoded secret patterns: password\s*=, api_key\s*=, SECRET\s*=, token\s*= (case-insensitive, exclude .env.example)
   • Placeholder strings: TODO, FIXME, impl later, stub, placeholder (in source files only)
   • Missing error handling: look for calls to external systems (fetch, axios, db., fs., open(), connect()) without adjacent try/catch or .catch()

4. Use Read to check .gitignore for .env entries.

5. Use Grep to search README.md for setup instructions (clone, install, run).

6. Detect package manifests (package.json, requirements.txt, go.mod, Gemfile, composer.json) and inspect dependency versions:

   • Flag any version set to *, latest, or an unbounded range such as >=X with no upper bound.
   • Flag packages with no updates in 2+ years — look for deprecation notices in the package README or description field.
   • Flag known abandoned or replaced packages (e.g. request → use axios/fetch; moment → use date-fns/dayjs).
   • Confirm a lockfile is present and committed (package-lock.json, yarn.lock, poetry.lock, go.sum, Gemfile.lock, etc.).

7. Check for performance red flags:

   • If a webpack.config.* or vite.config.* exists, note whether bundle size budgets are configured; flag if estimated bundle likely exceeds 500 KB.
   • Grep list/find/getAll endpoint handlers for array returns that lack limit, offset, or page parameters (missing pagination).
   • Grep for readFileSync and execSync outside of config-loading or startup modules — flag any found in async request handlers.
   • Scan schema files (.sql, prisma/schema.prisma, **/models.*) for foreign key columns that lack a corresponding index definition.

8. For each checklist item below, determine: PASS, FAIL, or N/A (with written justification).

9. Produce the MVP Readiness Report (see Output Format).

MVP Checklist

1. Stability & Error Handling

• All external calls (DB, API, file system) have try/catch/except blocks or equivalent error checks.
• The application does not crash on invalid input — provides a clean error message and exits/returns gracefully.
• Repeated runs do not cause duplicate data or corrupted state (idempotency, where applicable).

2. Configuration & Environment

• The app validates required environment variables or config files on startup and fails fast if missing.
• No hardcoded "magic strings," URLs, or ports — all moved to config or env.
• No secrets committed to the repo (.gitignore covers .env and credential files; Grep finds no secrets in code).

3. Logging & Observability

• Logs include timestamps and severity levels (INFO, WARN, ERROR).
• No silent failures — every error condition is logged with enough context to debug.

4. Security (Golden Rules)

• All user input (CLI args, HTTP params, file contents) is validated or sanitized before use.
• The app only requests minimum permissions it needs (least privilege).
• Sensitive features are off by default unless explicitly configured (secure defaults).

5. Documentation & UX

• README explains how to go from "clone" to "run" in fewer than 3 steps.
• Help commands (--help) or README usage examples are provided.
• (For web projects) Meets WCAG AA contrast and works on mobile.

6. Implementation Integrity

• No placeholder or "impl later" comments in production code paths.
• Naming follows camelCase (or the language convention documented in docs/assumptions.md).
• README includes stack, license, and troubleshooting sections.

7. Dependency Health

• All dependency versions are pinned or range-constrained (no * or latest).
• No obviously abandoned or deprecated packages in use.
• A lockfile exists and is committed (package-lock.json, yarn.lock, poetry.lock, etc.).

8. Performance Baseline

• No obvious N+1 query patterns or unindexed foreign keys in schema.
• List endpoints implement pagination.
• No synchronous blocking calls in async request handlers.

Output Format

Produce a markdown report in this exact format:

MVP Readiness Report — —

Summary

Status: READY / NOT READY Blockers:

Checklist Results

Blockers (must fix before MVP)

• [#2] src/cli.ts:42 — CLI crashes on non-numeric --port. Add input validation before parseInt.
• [#8] Dependency Health — moment is abandoned; replace with date-fns or dayjs. Commit the lockfile.
• [#9] Performance Baseline — GET /users (src/api/users.ts:34) returns unbounded array; add limit/offset query params.

N/A Items

• [#X] reason (e.g. "No web UI — accessibility check not applicable")

The project is NOT MVP-ready if any item is FAIL unless explicitly marked N/A with written justification.
