deep-test

deep-test is a skill for Claude Code, Codex from kunalsuri/ai-fication-kit. It costs 49 tokens per session (394 once invoked), scanned A, original, Apache-2.0.

A strict codebase verification workflow that runs smoke tests, checks documented claims and structural drift, scans for license headers, and detects unreplaced template placeholders.

In plain words
What is it for?
Use it after changes or when checking overall code health. Run it with the project's deep-test command after ensuring the required Node.js dependencies are installed.
Why use it?
It catches broken behavior, mismatches between code and documentation, missing project files, licensing omissions, and template variables accidentally left in released files.

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

deep-test 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 1mo 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.

What it actually says

Deep test the codebase

This skill performs a thorough and strict verification of the codebase to guarantee that changes are clean, functional, matches Conventions, contains proper license headers, and does not leak template placeholders.

1. Prerequisites

Ensure you have the required runtimes and node dependencies installed:

  • Node.js (>= 18)
  • Run npm install before running tests if dependencies are updated.

2. Run the Deep Test

Run the automated deep test script via npm:

npm run deep-test

3. Verify Output

The script automatically tests:

  • Smoke tests: node test/run-tests.mjs
  • Document Claim verification: node install.mjs verify . --strict
  • Structural Drift verification: node install.mjs drift . --strict --git (falls back to --strict without --git if git is not available)
  • License Headers check: Scans files for copyright markers.
  • Unresolved template placeholders: Confirms template variables are not leaked outside of templates/.

If any of the checks fail, print the failures verbatim and address them before declaring success.

4. Manual Verification / Check Checklist

  • If you introduced new files, check that their paths are added to the appropriate catalog or map (e.g., ai/guide/MODULE_MAP.md) and labeled as [inferred].
  • Verify the change adheres to all project rules in AGENTS.md and conventions in ai/guide/CONVENTIONS.md.

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.
