Automation mode: Resolve modes.automation (project.local.yaml →
project.yaml → default collaborative). Every AskUserQuestion call and
every file write follows .claude/docs/automation-modes.md
(collaborative asks always · guided major-only · autonomous logs and proceeds;
automation_always_ask categories always prompt).
Runs an improvement loop on a single skill: test → fix → retest → keep or revert.
Read the skill name from the first argument. If missing, output usage and stop:
Usage: /skill-improve [skill-name]
Example: /skill-improve tech-debtVerify .claude/skills/[name]/SKILL.md exists. If not, stop with:
"Skill '[name]' not found."
Run /skill-test static [name] and record the baseline score:
Display to the user:
Static baseline: [N] failures, [M] warnings
Failing: Check 4 (no ask-before-write), Check 5 (no handoff)If the static result is NOT ASSESSED (the skill file could not be read or parsed), stop and report it with its reason: there is no score to improve, and 0 FAILs from a file nobody could read is not a clean result.
If baseline is 0 FAILs and 0 WARNs, note it and proceed to Phase 2b.
Look up the skill's category: field in CCGS Skill Testing Framework/catalog.yaml.
If no category: field is found, display:
"Category: not yet assigned — skipping category checks."
and skip to Phase 3.
If category is found, run /skill-test category [name] and record the category baseline:
Display to the user:
Category baseline: [N] failures, [M] warnings ([category] rubric)A category result of NOT ASSESSED (a rubric section the skill-test could not find or apply) is reported with its reason and is not a zero: the category dimension is then excluded from "already passes" below.
If BOTH static and category baselines are 0 FAILs and 0 WARNs — and neither is NOT ASSESSED — stop: "This skill already passes all static and category checks. No improvements needed."
Read the full skill file at .claude/skills/[name]/SKILL.md.
For each failing or warning static check, identify the exact gap:
context: fork set but fewer than 5 phases foundFor each failing or warning category check (if category was assigned in Phase 2b), identify the exact gap in the skill's text. For example:
modes.workflow (PR at minimal, TD + PR at standard,
all 4 at full)Show the full combined diagnosis to the user before proposing any changes.
Write a targeted fix for each failure and warning. Show the proposed changes as clearly marked before/after blocks. Only change what is failing — do not rewrite sections that are passing.
Ask: "May I write this improved version to .claude/skills/[name]/SKILL.md?"
If the user says no, stop here.
Record the current content of the skill file — the exact text, kept in this conversation — so Phase 6 can restore it.
Write the improved skill to .claude/skills/[name]/SKILL.md.
Re-run /skill-test static [name] and record the new static score — measured by that run, never stated from the edit.
If a category was assigned, also re-run /skill-test category [name] and record the new category score.
Display the comparison:
Static: Before [N] failures, [M] warnings → After [N'] failures, [M'] warnings
Category: Before [N] failures, [M] warnings → After [N'] failures, [M'] warnings (if applicable)
Combined: [before] → [after] (improved / no change / worse)[before] and [after] are the Phase 6 combined counts — failures plus
warnings, both dimensions — e.g. Combined: 3 → 0 (improved).
Count the combined failure total: static FAILs + category FAILs + static WARNs + category WARNs. A re-test that comes back NOT ASSESSED (for example, the edit broke the frontmatter so the file no longer parses) is never an improvement, whatever its counts: take the "did not improve" branch below.
If combined score improved (combined failure count is lower than baseline): Report: "Score improved. Changes kept." Show a summary of what was fixed in each dimension.
If combined score is the same or worse:
Report: "Combined score did not improve."
Show what changed and why it may not have helped.
Ask: "May I restore .claude/skills/[name]/SKILL.md to the content it had before this run?"
If yes: write the content recorded in Phase 5 back to the file with Write; if no, leave the file as written. Never
git checkout it — that returns the last committed version and discards any edits
made before this run that were not yet committed.
