# Improve: an outside idea, judged against the system that exists Plan item 2d of the morning-brief overhaul (Bloom's `improve` pass). The founder pastes an idea. This skill answers one question: does it change how the SYSTEM works, and is that change already here? ## The two halves 1. **Deterministic (this skill must run it, never reason from memory):** ```bash python3 plugins/kipi-core/skills/improve/scripts/improve_ground.py --target <rule|lint|hook|trigger|context|skill|prompt|test|script|job> "<idea in one sentence>" ``` It prints a JSON verdict with `cites` (lessons paths or named files) and a `corpora` report saying which lessons directories were read, missing or unreadable. Exit 0 for `already-built` / `adopt`, 2 for `skip`. Set `KIPI_LESSONS_CORPORA=/path/one:/path/two` to ground against more than this instance's corpus; the report names each one either way. 2. **Judgment (the skill):** read what the script cited. Then write the critique in this shape: - The idea, in one sentence, as a SYSTEM change (a stage, a trigger, a rule, a context entry). If it cannot be phrased that way it is roadmap, and the verdict is skip regardless of how good the idea is. - What already exists: the cited file or lesson, opened, with the line that covers it. Not "we have something like that". - Verdict: `already-built` (name the file), `adopt` (name the smallest change and the check that would prove it), or `skip` (name the rea
