Create a new agent skill (or Claude Code slash command) from a plain-language description, using live spec fetching, pattern research, and an approval-gated blueprint before any files are written. Use whenever the user wants to build, scaffold, or author a new skill, subagent capability, or slash command, including phrasings like 'make a command for X', 'create a slash command', 'turn this into a reusable skill', or 'package this workflow as a skill'. Not for editing CLAUDE.md/AGENTS.md memory…
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
# Create Skill
Create new agent skills with specification-driven generation, backed by live documentation fetching and interactive planning.
`<skill-dir>` below is this skill's directory.
## Writing Philosophy
Apply these when drafting the generated skill's description and body in Phase 4: they make the difference between a skill that works once vs. one that works reliably across varied inputs:
**Descriptions lead with use case.** Open with the concrete use case, then the trigger phrases a user would actually type: third person, WHAT the skill does + WHEN to use it. If a sibling skill covers adjacent territory, add one "Not for X (use <sibling>)" clause per real overlap: that single clause prevents more wrong triggers than three extra trigger phrases. Cap at 1024 chars (the bundled validator enforces it).
**Explain WHY only at hard boundaries.** Add reasoning only where an agent would otherwise plausibly do the wrong thing (e.g. "fetch live specs: cached docs go stale within weeks"). Everywhere else, a plain imperative ("Run the validator.") is faster to read and no less correct. Justifying every line is noise, not guidance.

How to install
mdr add mgiovani/cc-arsenal/create-skill@sha256:48d2a1d809161c37The line at the top of this page pins the label v3.0.0, 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.
