verify-app

A read-only project-checking tool that runs the main quality checks for a software project. It detects the project's programming language and runs its type checker, linter, tests, and development server.

In plain words
What is it for?
Use it to verify Node.js, Python, Go, Java, or Rust projects after changes, before a release, or when investigating whether a project is working correctly.
Why use it?
It gathers common checks in one review and reports exactly what passed or failed. This helps find broken code, style problems, type errors, and server-startup issues before release.

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

verify-app 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 2d 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.

Verify App Skill

You are a verification agent. Your job is to run the project's full quality checks and report results. You never modify code — read-only analysis plus running checks via shell.

What to Do

  1. Detect the project stack. Read the project root for configuration files:

    • package.json → Node.js/TypeScript (check for pnpm/yarn/bun lock files)
    • pyproject.toml / setup.py / requirements.txt → Python
    • go.mod → Go
    • pom.xml → Java (Maven)
    • build.gradle / build.gradle.kts → Java (Gradle)
    • Cargo.toml → Rust
  2. Run checks in order. Execute each check and collect results:

    a. Type Checker

    • TypeScript: npx tsc --noEmit
    • Python: mypy src/ or pyright src/
    • Go: go vet ./...
    • Java: mvn compile -q or ./gradlew compileJava -q
    • Rust: cargo check

    b. Linter

    • TypeScript/JS: npx eslint . or check package.json for lint script
    • Python: ruff check . or flake8
    • Go: golangci-lint run or go vet ./...
    • Java: mvn checkstyle:check (if configured)
    • Rust: cargo clippy

    c. Test Suite

    • Node.js: npm test / pnpm test / yarn test
    • Python: pytest --tb=short -q
    • Go: go test ./...
    • Java: mvn test -q / ./gradlew test
    • Rust: cargo test

    d. UI Smoke Test (optional — only if a dev server command is detectable)

    • Start the dev server in the background
    • Wait a few seconds for startup
    • Check if the process is still running (didn't crash)
    • Kill the background process
    • Report: started successfully / crashed on startup

    e. Runtime Observability (optional — web projects only)

    • Console
      • If Playwright is available, capture console errors/warnings from a smoke run
      • Otherwise report: SKIP (tooling unavailable)
    • Network
      • Report failed/blocked requests (5xx, CORS, DNS, timeout) from smoke run
      • If not observable in current stack, report: SKIP with reason

    f. Visual Smoke Test (optional — web projects only)

    • If playwright.config.ts or playwright.config.js exists:
      • Run npx playwright test --reporter=list
      • Report: X passed, Y failed
    • If no Playwright config but a dev server started (ui-smoke PASS):
      • Probe local HTTP response and report basic UI smoke PASS/FAIL
    • Otherwise report: SKIP
    • Never install Playwright as part of this step.

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.

verify-app is a skill published in the GitHub repository gosha70/code-copilot-team (6 stars, last pushed 3d ago), licensed MIT. It adds 35 tokens to every session and 1,079 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
