Use when the user asks to generate, update, refresh, or sync documentation for the repo. Scans public API surface + tests + existing docs, proposes JSDoc/docstrings/README/CHANGELOG updates, then runs two polish passes for tightness and link/example correctness. NOT iterative — fixed 3-round pipeline (generate + polish + polish). Can only edit docblocks in source files, never logic; can create/update doc files freely. Not for writing new code (use xo-build), not for refining source logic (use xo-polish).
EnglishUse when the user asks to fuzz, stress-test, property-test, or find crashes in existing code. Runs fast-check property-based fuzzing on module exports. This mode is deterministic — no subagents or API required. Distinguishes AdapterErrors (expected rejections) from real bugs (TypeError/RangeError/etc). Writes crash corpus for CI replay.

Xo Docs
Use when the user asks to generate, update, refresh, or sync documentation for the repo. Scans public API surface + tests + existing docs, proposes JSDoc/docstrings/README/CHANGELOG updates, then runs two polish passes for tightness and link/example correctness. NOT iterative — fixed 3-round pipeline (generate + polish + polish). Can only edit docblocks in source files, never logic; can create/update doc files freely. Not for writing new code (use xo-build), not for refining source logic (use xo-polish).
Xo Fuzz
Use when the user asks to fuzz, stress-test, property-test, or find crashes in existing code. Runs fast-check property-based fuzzing on module exports. This mode is deterministic — no subagents or API required. Distinguishes AdapterErrors (expected rejections) from real bugs (TypeError/RangeError/etc). Writes crash corpus for CI replay.
