verify

verify is a skill for Claude Code, Codex from itsribbZ/Godspeed. It costs 73 tokens per session (915 once invoked), scanned A, original, MIT.

A project health-check skill that detects the project type and runs suitable build, test, or syntax checks. It supports common Python, JavaScript, C/C++, Rust, Go, Make, and Unreal Engine project layouts.

In plain words
What is it for?
Use it after code changes or when checking whether a project works. It can compile Python, run pytest, build and test Node projects, build CMake projects, check and test Rust and Go projects, and run Make targets when available.
Why use it?
It replaces a series of manual checks with one pass/fail result and a short explanation of the first failure. By default, it stops when a check fails.

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 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 4d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verify — Build & Test Health Check

Triggers: "verify", "check build", "does it work", "run tests", "health check", "is this green"


What it does

Inspects the current working directory, matches it against a project-type signature, and runs the corresponding verification commands. One pass/fail verdict with an error summary if anything breaks.

Defaults to fail-fast — the first failing command stops the sequence unless the user explicitly asks for a full sweep.


Project-Type Detection

Signature file Detected type Verification commands
pyproject.toml OR setup.py OR requirements.txt OR *.py at root Python python -m py_compile $(git ls-files '*.py')pytest -x if a tests/ dir exists
package.json Node / JS npm run build (if defined) → npm test (if defined)
CMakeLists.txt C / C++ (CMake) cmake --build build → optional ctest
Cargo.toml Rust cargo checkcargo test
go.mod Go go build ./...go test ./...
Makefile make make -n (dry run) then make test if defined
.uproject Unreal Engine 5 SKIP — requires the Editor; report "UE5 project detected, manual verify required"
A custom scripts/verify.sh or .verify file User-defined Run it
No matches Unknown Report the directory contents and ask

If multiple signatures match (monorepo), run them in parallel and aggregate results.

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.
