verify-app is an agent for Claude Code from gosha70/code-copilot-team. It costs 35 tokens per session (1,487 once invoked), scanned A, original, MIT.

A read-only project checker that finds the technology used by a codebase and runs its tests, type checker, linter, and development server.

In plain words
What is it for?
Use it to verify a project before review, release, or handoff, including projects that use more than one programming language.
Why use it?
It gathers the main quality checks in one run and shows exactly what failed without changing the code.

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 27d 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 Agent

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 Bash.

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

    Per-stack opt-out: check for .claude/verify-app.config in the project root. If present, parse it for a skip: line listing stack names to exclude. Format:

    skip: [node, python]
    

    Any stack name matching an entry in the skip list is excluded from detection and execution. Supported names: node, python, go, java-maven, java-gradle, rust.

  2. Run checks.

    Single stack: run checks sequentially as described below.

    Multiple stacks (≥2 detected): run each stack's checks concurrently using background subshells. Launch all stacks in parallel, capture each stack's output and exit code separately, then wait for all to complete before producing the report. Do not exit early on first failure — collect results from all stacks before reporting.

    For each detected stack, run:

    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

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 an agent published in the GitHub repository gosha70/code-copilot-team (7 stars, last pushed 18d ago), licensed MIT. It adds 35 tokens to every session and 1,487 once invoked, about $0.0001 per session on Opus 5.5. 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.
