Skill Creator (daymade edition)

A meta-skill for authoring new Claude Code skills, upgrading existing ones, and proving the change worked with tiered evals.

What it does

  • Authors new skills by capturing intent (purpose, trigger phrases, output format) and drafting a SKILL.md bundle.
  • Upgrades existing skills safely: snapshot the old bundle first, then run a regression audit so no runtime contract, reference, or eval quietly disappears.
  • Picks the cheapest sufficient verification tier: targeted checks for bounded fixes, sampled behavior replay for uncertain instruction edits, full paired A/B eval pipeline for new or high-risk work.
  • Optimizes trigger accuracy with a dedicated description-improver script.
  • Three specialized distillations: wrap a session into a skill, mine chat history for reusable patterns, and learn preferences from an approved artifact corpus.
  • Handles coexistence with the official skill-creator plugin via an opt-in SessionStart precedence hook.

Who it's for

  • Power users and teams maintaining a growing library of skills
  • Anyone whose skill exists but never fires at the right moment
  • Authors who have lost behavior during a "cleanup" rewrite
  • People shipping taste-driven skills (writing style, report tone) who still want a feedback loop

Examples

  1. "Turn this deploy-check session into a skill" → it extracts commands, ordering, and helper scripts into a SKILL.md + scripts bundle.
  2. "My report skill stopped triggering" → it rewrites the description, then replays real historical prompts old-vs-new to confirm the change is followed.
  3. "Refactor my data-analysis skill" → snapshot, edit, regression audit of every unmatched old unit, plus an independent fresh-context review written to a private review log.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the daymade-skill/skill-creator folder from the GitHub repo daymade/claude-code-skills into my ~/.claude/skills/daymade-skill-creator/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git && mkdir -p ~/.claude/skills && cp -r claude-code-skills/daymade-skill/skill-creator ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal (Terminal on macOS; WSL or Git Bash on Windows).
  2. Clone the repo: git clone https://github.com/daymade/claude-code-skills.git
  3. Make sure the skills folder exists: mkdir -p ~/.claude/skills
  4. Copy just this skill: cp -r claude-code-skills/daymade-skill/skill-creator ~/.claude/skills/
  5. Make the bundled scripts executable: chmod +x ~/.claude/skills/skill-creator/scripts/*
  6. Restart Claude Code and say "help me create a skill" to confirm it activates.
  7. If you already have the official skill-creator plugin, the skill will offer a precedence hook — install it only if you want deterministic routing (undo with scripts/setup_supersede_hook.sh uninstall).
