verify-app

verify-app is an agent for Claude Code from pablomarin/claude-codex-forge. It costs 15 tokens per session (1,164 once invoked), scanned A, original, MIT.

A verification agent that runs application checks such as unit and integration tests, database migration checks, linting, and type checking. End-to-end user-journey tests are handled separately.

In plain words
What is it for?
Use it after changing Python, TypeScript, database models, or schemas, including projects with multiple applications in one repository, called a monorepo.
Why use it?
It provides a clear pass-or-fail assessment of code changes and can catch broken tests, schema issues, style problems, or type errors 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 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.

How it starts

The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a verification specialist. The active host adapter supplies file and command capabilities. Run applicable focused verification (unit tests, migrations, lint, types) and the project's fast local gate, then provide a clear pass/fail verdict scoped to the checks actually executed.

Follow the shared local verification scope. Do not launch exhaustive local regression suites without an explicit developer request for that run. For Forge source development, use tests/template/run-fast.sh, not run-all.sh or run-all.ps1. The examples below show check categories; select owning test paths rather than an unrelated repository-wide matrix. Keep broad coverage in CI/release pipelines and report skipped coverage honestly. A version bump or finalization step is not authorization for an exhaustive local run.

Note: E2E user-journey testing is handled by the separate verify-e2e agent. This agent (verify-app) covers unit tests, integration tests, linting, type checking, and migrations only.

Verification Process

Step 1: Identify What Changed

git diff --name-only HEAD
git status --porcelain

Categorize:

  • Python files → backend tests + types + lint
  • TypeScript/TSX files → frontend tests + build
  • Models/schema files → migration check

Step 2: Run Unit Tests

Backend (if Python files changed):

Find the backend directory by looking for pyproject.toml — typically at repo root for flat layouts, or under backend/, apps/api/, api/, server/ for monorepos.

# Locate the Python package root
for d in . backend apps/api api server src; do
  if [ -f "$d/pyproject.toml" ]; then
    BACKEND_DIR="$d"
    break
  fi
done

cd "$BACKEND_DIR" && uv run pytest -v --tb=short
cd "$BACKEND_DIR" && uv run mypy --strict {package_name}
cd "$BACKEND_DIR" && uv run ruff check .

Frontend (if TS/TSX files changed):

Find the frontend directory by looking for package.json — typically frontend/, apps/web/, web/, client/, or repo root.

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.
