unit-test-generator

unit-test-generator is a skill for Claude Code, Codex from conectlens/lenserfight. It costs 15 tokens per session (87 once invoked), scanned A, original, MIT.

A test-planning tool that turns changed software behaviour into focused unit and integration tests.

In plain words
What is it for?
It helps define test cases, regression coverage, mocks, fixtures, assertions, and tests that are not worth adding.
Why use it?
It helps developers cover normal cases, edge cases, invalid inputs, and past bugs without writing duplicate tests.

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-generator 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 2d 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

Unit Test Generator

For [[behavior]], produce a test plan with:

  1. Happy path tests.
  2. Edge cases and invalid input.
  3. Regression tests for previously broken behavior.
  4. Mocks, fixtures, and assertions needed.
  5. Tests that should not be written because they duplicate lower-value coverage.
Changes

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.
