Documentation

README

Excerpt

Assess Impact

HARD GATE — Run this skill before plan-work whenever a change touches an existing module, symbol, or file used by more than one caller. Skip only for net-new code with no existing dependents.

Find the blast radius of the proposed change before a single line is written.

Modes

Default: full impact analysis (dependents + affected stories + test coverage mapping)
--lightweight: Fast fan-in/fan-out only (<10s). Maps callers and imports without test coverage mapping. Used by build-epic step 2 as a pre-plan gate. Risk score > 7 triggers a mandatory grill-me session before proceeding.

This is the opening of the README. Read the full README on GitHub.
