Requirements
This skill needs the full UX/UI Agent Skills kit: the gates, the references and
the design-system library. Install it with npx [email protected] init
or as the Claude Code plugin. npx [email protected] add copies the skill folder and
nothing else, and this skill has no guidance-only mode: its whole job is to
read what the kit's hooks recorded, so without the kit there is nothing for it to do.
Step 0: is the kit here? Check once:
ls ${CLAUDE_SKILL_DIR}/../../../scripts/observe.mjs >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSINGOnKIT_MISSING, say plainly that only the skill folder was installed, name the install command above, and stop. Do not guess the contents of a file you could not open, and do not report a result you did not produce.
Report what the hooks recorded - never a reconstruction from memory.
- Run
node ${CLAUDE_SKILL_DIR}/../../../scripts/observe.mjs --project "$CLAUDE_PROJECT_DIR"(or without--projectwhen the user asks about every project, and with--days Nwhen they name a window). - Quote the summary lines it prints. If it says no session edited UI, say that and stop: there is nothing to judge.
- For each session marked
BROKE A RULE, run it again with--session <id>and say which rule failed and the timeline line that shows it. - If the user wants the page, run it with
--html <path>and give the path.
What it measures, and what it does not: three counted rules per session -
every edited page had a passing gate before the end, no fast-gate finding was
left on a file's latest version, and the agent never finished while the Stop
hook still had pages open. It says nothing about design quality, and an
unfinished session is not counted for or against.
