A skill earning its place in the lacquer (per skill-authoring-standard) is a judgment call today. This loop adds a second, empirical bar: does a proposed edit measurably reduce the friction real sessions hit, without regressing what already works? Run it via the skill-tuning-loop Workflow — never edit a skill's behavior-affecting content based on mined evidence without going through the validation gate below.
Skill Tuning Loop is a community-contributed Claude Code skill in the content-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/skill-tuning-loop/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when a skill in core/skills/ or profiles/*/skills/ keeps getting corrected in practice, when triaging a scheduled tuning-pass PR, or when skill-authoring-standard's manual rubric isn't enough to tell whether a proposed edit actually helps. Distinct from skill-authoring-standard (a static prose rubric checked by a human) — this is an empirical, evidence-gated loop checked by rollouts.
The Skill Tuning Loop Claude Code skill is built for content creators, marketers, copywriters, SEO professionals, and editorial teams. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 213,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
