Design a new Claude Code skill from a concrete use case and produce a repo-ready skill package. Use when the user asks to create a new skill, define a skill's responsibility, draft SKILL.md, choose frontmatter, design supporting files, or prepare eval criteria for a new skill. Also trigger on "スキルを作りたい", "スキルを作って", "スキルを追加して", "新しいスキル", "SKILL.md生成".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Pattern declaration Primary pattern: Pipeline Secondary patterns: Inversion Why: skill creation requires strict phase order (requirements → pattern selection → structure → review) with an upfront question-gathering gate. ## Purpose Create a new skill only after the use case is concrete enough. Your job is to: 1. identify the smallest useful responsibility 2. select the right design pattern 3. define when the skill should trigger 4. choose safe frontmatter defaults 5. draft a minimal but strong `SKILL.md` 6. propose supporting files only when they add clear value 7. define an initial eval set ## Safety constraints Write output files only to `.claude/skills/` unless the user explicitly specifies a different path. Do not modify existing skills without user confirmation. Note: this skill does not set `disable-model-invocation: true` because file creation is its primary purpose, not an incidental side effect. The settings.json deny list and user confirmation prompts provide sufficient guardrails. ## Core rule Do not create a broad or fuzzy skill. Prefer: - one responsibility - one primary workflow - one clear success condition …

How to install
mdr add s977043/river-review/skill-creator@sha256:d05cfcfe66aacb56The line at the top of this page pins the label git:20261004.95d1f7a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
