skill-creator is agent-read markdown (skill) from lstr-1/skills: Use when creating a new skill from scratch, modifying an existing skill, or optimizing a skill's triggering description. Guides intent capture, structure, writing patterns, and progressive-disclosure organization so skills reliably trigger and stay maintainable. Trigger on phrases like "turn this into a skill", "write a skill for X", "improve this skill", "my skill isn't triggering"..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Skill Creator
A process skill for writing skills well.
Adapted from [anthropics/skills/skill-creator](https://github.com/anthropics/skills/tree/main/skills/skill-creator) — we keep the authoring workflow and progressive-disclosure guidance but drop the Python eval-viewer harness (not part of our stack).
## The loop
1. **Capture intent** — what should the skill do? When should it trigger?
2. **Draft** SKILL.md with frontmatter + body
3. **Test** — 2–3 realistic prompts, see if Claude triggers + executes right
4. **Improve** based on failures (wrong trigger, wrong output, over-verbose, etc.)
5. **Optimize description** if triggering is unreliable
## 1. Capture Intent
If the user said "turn X into a skill", extract from conversation history: the tools used, the sequence of steps, corrections the user made, input/output formats observed. Confirm gaps before proceeding.
Ask explicitly:
1. What should this skill enable Claude to do?
2. When should it trigger? (user phrases / contexts)
3. What's the expected output format?
4. Does this skill have objectively verifiable outputs? (if yes, test cases help; if subjective like writing style / art, skip them)
## 2. Write the SKILL.md

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
