Skill Creator Plus
Audits, creates and improves Agent Skills (folders with a SKILL.md) against Anthropic's skill authoring best practices, the Claude Code skills docs and the prompting guides for newer models such as Claude Fable 5 and Opus 5.5. Audit mode reports every rule as pass, fail or not applicable, with file and line evidence and a proposed fix, and changes nothing until the user approves. Use when the user asks to audit, review, check or score a skill or a folder of skills, to create a new skill or turn a repeated workflow into one, to improve, shorten, refactor or update an old skill for newer models,

From the SKILL.md
# Skill Creator Plus Audits, builds and improves skills so Claude takes the same process on each run. A skill is a table of contents, not a manual: the description gets it chosen, SKILL.md says what to do, and detail waits in reference files until a step needs it. ## Rules for every mode 1. **Report before you change.** Start from evidence: the validator's output and a full read of the skill. In AUDIT, edit nothing until the user picks which findings to fix, because a skill change alters each future run and the user owns that call. A direct request to fix a named problem is already that approval. 2. **Absorb, don't layer.** Fold new guidance into the rule it refines and delete what it replaces. A good edit usually leaves the skill shorter. Write the reason, not the date, so a later editor can tell whether the rule still holds. 3. **Test before you delete.** Newer models often do better with fewer instructions, but only a with-skill and without-skill run proves a line is dead weight. Method: references/testing.md, "Test before you delete". 4. **The validator is the floor.** `scripts/validate_skill.py` checks what a script can check. The judgment rules in references/audit-checklist.md need a careful read. ## Pick the mode | Mode | When | Output | |---|---|---| | AUDIT | A skill or a folder of skills should be checked, scored or improved | A findings report, then only the approved edits |
