testing-pyramid

testing-pyramid is a skill for Claude Code from cembasaranoglu/crafting-system-claude. It costs 39 tokens per session (117 once invoked), scanned A, original, MIT.

A framework for designing a testing strategy across different levels, from small unit tests to full end-to-end checks. Unit tests check one small part of a program, while end-to-end tests check a complete user flow.

In plain words
What is it for?
Use it to map existing tests, plan unit, integration, contract, smoke, fuzz, benchmark, or end-to-end coverage, and prioritize additions.
Why use it?
It helps reveal missing coverage and flaky-test risks without treating every test as equally useful or expensive.

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

testing-pyramid 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.

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.
