final-check

final-check is a skill for Claude Code, Codex from JeonJe/claude-plugins. It costs 118 tokens per session (1,569 once invoked), scanned A, original, MIT.

A final review process for checking that a software deliverable meets its requirements and can be used by someone without your private context.

In plain words
What is it for?
Use it before submitting, sharing, reviewing, or publishing a project.
Why use it?
It catches missing requirements, unreproducible setup steps, exposed secrets, personal data, and other handoff problems.

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

final-check 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.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Final Check

Deliverable-side quality gate, run after implementation and review are done and before the work leaves your machine. The reader on the other side has none of your context — this gate verifies the artifact stands alone.

Every check produces evidence (command output, file citation). A check without evidence is ❓, never ✅.

Phase 1 — Requirements coverage map

Take the original requirement source (spec document, issue, request message) and build the coverage table from the requirements side, not from what you built:

# Stated requirement Where implemented (file/symbol) Where verified (test/manual evidence) Status
  • Status: COVERED / PARTIAL (state what's missing) / NOT COVERED (state why — deliberate descope needs one line of reasoning the reader will see) / EXTRA (built but never asked — flag it; unrequested scope reads as not understanding the ask).
  • Ambiguous requirements you interpreted: record the interpretation and where it's documented for the reader.
  • No requirement source available → reconstruct the implied checklist from the deliverable's own README/claims, and verify the artifact delivers what it promises.

Phase 2 — Clean-clone reproducibility

The single highest-failure gate. Verify in an isolated copy, not your working tree:

git clone <repo> /tmp/final-check-clone && cd /tmp/final-check-clone
# then follow README literally, top to bottom
  • Execute the README's setup/run/test instructions exactly as written — no steps from memory. Every command you must run that the README doesn't mention is a README bug.
  • Check declared prerequisites vs reality: language/runtime version, package manager, required env vars (is there an .env.example?), external services (DB, docker) — can the reader actually satisfy them?
  • Run the test suite from the clean clone and record the fresh output. "It passed earlier in my working tree" is not evidence.
  • If a step cannot be run in your environment, mark it ❓ with the reason — do not silently assume it works.

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.
