unit-test-loop

unit-test-loop is a skill for Claude Code, Codex from SomtoUgeh/somto-dev-toolkit. It costs 78 tokens per session (954 once invoked), scanned A, original, no licence file.

A workflow for adding and improving unit tests, which check small pieces of code separately. It includes guidance for React Testing Library, a tool for testing React interfaces, and test-driven development (TDD), where tests are written before or alongside the code.

In plain words
What is it for?
Use it to add tests to a module, increase test coverage, test React components, or follow a unit-testing workflow.
Why use it?
It gives developers a repeatable way to test code and improve coverage instead of deciding from scratch how each test should be written.

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

unit-test-loop 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 5d 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.
