Install
Skills CLI
npx skills add edonadei/caliper
Asks which skills and agents to install. Just one: npx skills add edonadei/caliper --skill evaluate-skill — add -g for every project.
Claude Code
git clone https://github.com/edonadei/calipercp -r "caliper/skills/evaluate-skill" ~/.claude/skills/
Copies the evaluate-skill skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add edonadei/caliper
Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.
Skills can run code on your machine — read the SKILL.md first.
What it does
In the author's own words, from each skill's SKILL.md.
-
evaluate-skill
Run, read, and diagnose a skill's Caliper eval — its success rate over k attempts, whether it fires, and whether it beats the agent without it. Use when the user wants to run, validate, interpret, or compare a skill's eval, or write an .eval.yaml spec whose tasks they have already decided.
skills/evaluate-skill/SKILL.md on GitHub (opens in a new tab) -
grill-skill
Interview the user to decide what a skill's eval should test, then build the spec and iterate until the skill ships. Use when the user wants help designing a skill's eval, has a skill with no eval, or wants to find what an existing eval misses.

save-note
Save a short note to a file. Use when asked to record, save, or jot down a note.

Review before you install
A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
