Skill Creator
Creates new skills from scratch, iterates on existing ones, and runs evals to benchmark performance with variance analysis before you ship.
Entry verified April 21, 2026
The short answer
A skill for creating new skills and iteratively improving them. Walks you through drafting the skill, writing test prompts, running Claude against them in the background, reviewing qualitative and quantitative results, then rewriting based on what the evaluation surfaced.
When to use it
When you want to turn a workflow already in your conversation into a reusable skill — the creator extracts tools used, step sequence, corrections, and input/output formats from chat history. Also for optimising an existing skill's description for better trigger accuracy, or benchmarking two variants side by side.
Setup
- 1
Install via the daymade-skills marketplace (see QUICKSTART.md in the upstream repo).
- 2
Invoke by describing intent — 'I want to make a skill for X' — and the creator asks what it should do, when to trigger, and expected output.
- 3
Uses AskUserQuestion aggressively at each decision point; accept the recommended option or pick 'Other' to steer.
- 4
Runs eval-viewer/generate_review.py to show benchmark results you can review alongside the skill output.
Example
You: /skill-creator pivot-sweep — refactor skill that sweeps CTAs with tier policy. Claude: Created ~/.claude/commands/pivot-sweep.md with frontmatter, description, invocation pattern, 3-step instructions. Review and fill in details.

Caveats
Template gets stale as the SKILL.md spec evolves — review quarterly against Anthropic docs.
