frontend-template: Skill for Codex

.cursor/skills/acceptance-verification/SKILL.md

acceptance-verification is a skill for Codex, Cursor from ddebixx/frontend-template. It costs 100 tokens per session (735 once invoked), scanned A, original, MIT.

A verification workflow for checking completed software against an approved specification and its acceptance criteria. It maps each required outcome to concrete evidence and does not modify the implementation during the check.

In plain words
What is it for?
Use it after features, refactors, behavioral bug fixes, integrations, or interface changes. It reviews changed code and project checks, then records tests, runtime scenarios, regressions, and any unverified requirements.
Why use it?
It prevents a passing test suite from being mistaken for proof that every requirement works. If there is no usable specification or testable criteria, it marks verification as blocked instead of inventing a standard.

Skill for CodexCursor

Written for Codex and Cursor: agents/openai.yaml present, but also installed under .cursor/.

This is ddebixx/frontend-template's own configuration. It tells Codex and Cursor how to work on frontend-template itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything frontend-template configures →

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

acceptance-verification 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 16d 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.

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Acceptance verification

Verification is a separate phase from implementation. During the verification pass, inspect and test; do not fix the code you are judging.

Workflow

  1. Locate the contract

    • Read the approved specification, implementation plan, relevant project rules, and changed code.
    • If no specification or testable acceptance criteria exist for non-trivial work, return BLOCKED: missing verification contract rather than inventing criteria after the fact.
  2. Establish the change surface

    • Identify changed files, public interfaces, user flows, data/state changes, dependencies, and likely regression areas.
    • Note any implementation behavior not represented in the spec.
  3. Create the acceptance matrix

  4. Run appropriate project checks

    • Inspect existing package scripts, CI configuration, and test conventions before choosing commands.
    • Run relevant build, typecheck, lint, unit, integration, or E2E checks when available.
    • Do not invent commands or tools that are not configured.
    • Record command and result summaries as evidence.
  5. Verify behavior, not only code shape

    • For UI work, inspect the rendered interface when browser tooling is available.
    • Exercise relevant happy paths and negative paths.
    • Check loading, empty, error, permission, long-content, responsive, keyboard, and reduced-motion states when required by the spec.
    • For APIs/data flows, verify inputs, outputs, validation, failure handling, compatibility, and persistence semantics where applicable.
  6. Check for regressions and scope leakage

    • Look for unintended behavior changes outside the specified scope.
    • Flag hidden coupling, stale code paths, missing cleanup, broken tests, incompatible contracts, or new behavior without specification coverage.

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.
