The meta-skill: build a new, high-quality Claude Agent Skill from scratch — or audit and improve one you already have. It's the tool for growing this marketplace, and it encodes the same standards every skill here was built to.
Runs a five-step loop: Scope → Draft → Reference → Test → Package.
- Scope — pins the job to one sentence, lists the trigger phrases, defines inputs/outputs, and flags anything that needs a safety gate. If it's really three jobs, it says so.
- Draft — writes two-key frontmatter (the description is what makes a skill trigger, so it's concrete and keyword-rich, ending in trigger phrases) and a tight, skimmable SKILL.md with a numbered procedure.
- Reference — moves long checklists, rubrics, templates, and examples into
reference/files, keeping the SKILL.md small (progressive disclosure). - Test — a trigger test (does the description fire for the right asks and not the wrong ones?) and a cold-run test (follow the SKILL.md on a real input and check the output).
- Package — as a plain folder, a
.skillzip for one-click install, or a plugin + marketplace entry with the install command.
Point it at an existing skill and it scores it against a 10-point rubric, then fixes the usual failures: a vague description that never triggers, a bloated SKILL.md that should push content to references, unclear scope, or a missing safety gate.
If you're building a skills library, this is the highest-leverage tool in it — it turns "I keep typing the same instructions" into a clean, installable, reusable skill, and keeps quality consistent across a growing set.
"create a skill," "make a skill," "build a skill for X," "turn this workflow into a skill," "write a SKILL.md," "improve this skill," "audit my skill," "why doesn't my skill trigger," "package this skill."
