Use when starting any TDD cycle, before writing any test file, editing any production file, running tests, or advancing a phase — required before any of those actions.
How to drive the vitest-agent MCP tools correctly — the non-obvious operational facts (run_tests scoping, why subset runs "fail" coverage, the consoleLeaks signal, the VITEST_AGENT_CONSOLE escape hatch, auto-recovered attribution) that otherwise cost trial-and-error.
Guide @vitest-agent/plugin configuration including thresholds, targets, output format, and plugin options. Use when setting up or modifying the plugin configuration.
Use when starting a dogfood session for the vitest-agent plugin in this repo, when continuing one from an existing handoff at docs/superpowers/dogfood/<chain>/, or after the TDD orchestrator subagent completes a dogfood task. Repo-internal — does not apply to projects that consume vitest-agent as a dependency.
Use when reaching any TDD phase transition — spike close, red→green, green→refactor, or discard — required before exiting the phase so each cycle lands as a discrete, greppable commit in git history.
Use when working to raise code coverage, target specific uncovered lines, or close the gap against the workspace's configured coverage thresholds and aspirational targets.

| description | Required before any production-code edit during the red phase. Forces externalization of "why I think this fix will work" with cited test_error_id and stack_frame_id evidence. |
Before editing production code in response to a failing test, call:
hypothesis (action: record)({
content: "<your hypothesis>",
citedTestErrorId: <test_errors.id from test_errors>,
citedStackFrameId: <stack_frames.id from the same error>
})
sessionId. The MCP server resolves the binding session from the recovered host context — for the tdd-task subagent that is its own running subagent session. A caller-supplied sessionId is ignored; in particular, do not pass the tddTaskId here (a common slip after the goal/behavior calls, which do take tddTaskId).citedTestErrorId and citedStackFrameId are required. A hypothesis without specific evidence is a vibe.hypothesis (action: validate)({ id, outcome: "confirmed" | "refuted" | "abandoned" }).The act of writing the hypothesis forces you to commit to a specific causal claim before you change code. If you can't write the hypothesis, you don't know enough to fix the bug yet — and your fix is statistically more likely to be a guess.
Flaky-triage and fix-failing-test workflows use this. The compliance hooks (Stop, SessionEnd) prompt for hypotheses if recent file_edits aren't cited.
