Skill Score

Q: What is a Claude Code skill and how does the Skill Score skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Skill Score is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Dev Tools category.

One repeatable pass that keeps the skill pack itself effective — the one surface no other scorecard grades. Runs the skill-effectiveness scorecard (`fak skill-effectiveness-scorecard`) over every .claude/skills/*/SKILL.md, reads the skill-debt work-list, and retires it worst-first by ADDING the real affordance — a sharp "Use when …" trigger, a reference that resolves on disk, the commit-by-path discipline a committing skill owes the shared trunk, a witness step, a scoped allowed-tools — never by spraying a keyword. Re-measures to PROVE skill-debt dropped, regenerates the committed snapshot, and commits only the skill lane by explicit path. An instance of the /score-2x loop pointed at the skill pack; the inward counterpart of agent-readiness (the agent's front door) and quality-score (the code). Use after adding or editing a skill, when a skill cites a tool that no longer exists, or on a /loop cadence to keep every skill discoverable, safe to operate, and trustworthy.

Is Skill Score safe to install?

A free static scan against the OWASP Agentic Skills Top 10 found no risk patterns in Skill Score’s SKILL.md — no data-exfiltration, prompt-injection, or unexpected-execution signatures. The full security scan is below.

Installing & verifying

Installing Skill Score writes its SKILL.md to ~/.claude/skills/skill-score/SKILL.md; Claude Code discovers it automatically on the next session — no restart flag needed. It declares no allowed-tools restriction, so it inherits your session’s existing tool access rather than narrowing it. To confirm it loaded, ask Claude to list its available skills — skill-score should appear by name.

What Skill Score needs to run

Worked code: 4 copy-paste code blocks in the body.
Depth: ~1,171 words, typical mid-range depth.

When to reach for it

There are 10 related skills in Dev Tools — a two-minute scan of the alternatives usually confirms whether Skill Score is the right pick.

From the source SKILL.md

The headline metric is skill-debt: the count of concrete, re-derivable affordances a skill is missing across nine KPIs in four groups (discover / operate / trust / economy). Driving it to zero means every skill is discoverable, safe to operate, and trustworthy by construction. The shape is the family's: run the scorecard → read the skill-debt work-list → retire debt worst-first (real affordances only) → re-measure and prove the drop → commit ONLY the skill lane by explicit path.

What this skill does

Skill Score is a community-contributed Claude Code skill in the tools-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/skill-score/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when …" trigger, a reference that resolves on disk, the commit-by-path discipline a committing skill owes the shared trunk, a witness step, a scoped allowed-tools — never by spraying a keyword. Re-measures to PROVE skill-debt dropped, regenerates the committed snapshot, and commits only the skill lane by explicit path.
