jaw-dev-testing

jaw-dev-testing is a skill for Claude Code, Codex from lidge-jun/cli-jaw-skills. It costs 91 tokens per session (8,482 once invoked), scanned A, original, no licence file.

A testing and quality-assurance guide for checking software behavior, including unit, integration, API, contract, and browser-based end-to-end tests. It also covers test-driven development (TDD), where tests are written before the code.

In plain words
What is it for?
Use it to plan or write tests, investigate test failures, set coverage or security checks, and add automated checks to continuous integration (CI).
Why use it?
It helps prevent old bugs from returning and makes releases easier to verify. It also provides a way to handle unreliable tests and coverage gaps.

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

jaw-dev-testing 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 9d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (examples/console_logging.py, examples/element_discovery.py, examples/static_html_automation.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
