How do I install the Bug Hunter skill?

Run npx skillmds@latest add octanejs/bug-hunter-3 in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Bug Hunter safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Bug Hunter?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Bug Hunter free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Workflow

State the suspected behavior
- Expected behavior, actual behavior, package, environment, and reproduction path.
- Decide whether the issue concerns runtime, compiler, SSR/hydration, Vite plugin, or an ecosystem binding.
Reproduce before fixing
- Add or locate the smallest failing test/fixture.
- For compiler/runtime behavior, prefer packages/octane/tests/_fixtures/*.tsrx plus a focused *.test.ts.
- For React parity, cite source React tests and use conformance/differential conventions.
- For ecosystem packages, use that package's tests/ harness.
Minimize
- Remove unrelated props, effects, timing, and DOM.
- Keep .tsrx fixtures tiny.
- Confirm the test fails for the intended reason, not setup/aliasing/jsdom.
Localize
- Runtime: inspect packages/octane/src/runtime.ts comments and closest tests.
- Compiler: inspect packages/octane/src/compiler/compile.js and emitted output if needed.
- SSR: inspect runtime.server.ts, server/index.ts, hydration tests.
- Bindings: compare existing package patterns and upstream React binding behavior.
Patch carefully
- Preserve documented intentional divergences.
- Prefer fixing owning source over weakening tests.
- Add regression coverage that would fail on the old behavior.
- Keep changes minimal and idiomatic.
Validate
- Run the new failing test until it passes.
- Run nearby affected tests.
- If runtime/compiler changed, consider wider packages/octane/tests or pnpm test depending on scope.
- Run pnpm typecheck when TS/API surfaces changed.
Report
- Root cause.
- Files changed.
- Tests added/updated and commands run.
- Any remaining risks or intentional divergences.

Common traps

React synthetic onChange, StrictMode double invoke, and class components are not bugs by default. Controlled value/checked is supported, but text editing uses native onInput; OCTANE_NATIVE_TEXT_ONCHANGE warns about likely React-style host wiring without changing native behavior. Deliberate commit-on-blur uses suppressNativeChangeWarning.
Differential innerHTML cannot catch render counts, effect timing, refs, focus, or node move sets.
jsdom layout/focus limitations can masquerade as library bugs.
