test-harnesslisted

Install vigiles and test a Claude Code harness — hooks, skills, agents, settings, CLAUDE.md — by picking the right tier (unit / deterministic / eval) and writing a test that passes. Use to check that a hook fires or blocks, that a skill triggers, that injected context lands; or to observe a run — which tools it called, whether it stayed inside its declared allowed-tools, what files and side effects it produced, how to intercept a call without executing it.

Test the Claude Code **harness** — the hooks, skills, settings, and CLAUDE.md that steer an agent — as the assembled machine it ships as. vigiles gives three tiers, cheapest first; this skill picks the right one, writes the test, and runs it. The guiding rule: **start at the cheapest tier that can answer the question, and climb only when it genuinely can't.** Two of the three tiers need no model and no API key, so they run on every commit for free — reach for the paid real-model tier only when the question actually requires a real model. ## Step 0 — Pick the tier (the judgment call) Match what you're testing to the cheapest tier that can answer it: | What you're testing | Tier | Cost | API | | -------------------------------------------------------------------------------------------------------------------------------------- | ----------------- | ------------------------------------------------ | --------------------------------------------------------------------------------------------- | | "Does this hook block/allow event X?" — pure hook logic, **every** event type (incl. Edit/Write, PreCompact, SessionEnd, SubagentStop) | **Unit** | free, milliseconds, no `claude` | `runHook`
