harness-skill-creator
Use when bootstrapping or tightening the smallest harness-oriented skill from an existing repository, workflow, evaluation corpus, or harness-analysis chain. Trigger for meta skills, reusable harness workflows, Qoder/Codex plugin skill sets, skill blueprints, and harness-analysis-like skills that need evidence-backed references, validation gates, and qodercli forward-tests.
npx skills add QoderAI/better-harness --skill harness-skill-creator --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Harness Skill Creator Create the smallest skill that makes another agent repeat one harness job with evidence, validation, and clear ownership. ## Workflow 1. Resolve source, target, and host: canonical `skills/<name>/`, `.agents/skills/` wrapper, or both. 2. Inspect the source chain before designing: entry `SKILL.md`, first-hop references, scripts, validators, templates, specs, tests, plugin manifests, and any real smoke evidence. 3. Load `references/bootstrap-patterns.md` after the first inventory. Use it to extract patterns, not product-specific rules. 4. Draft the minimum viable skill map: - skill name and trigger sentence - one job the skill owns - files to create under `skills/<skill-name>/`, usually `SKILL.md` plus one reference - evidence boundary and validation commands - forward-test prompt and pass/fail gates 5. Initialize new canonical skills with the system `skill-creator` helper when available. Add `scripts/` only for stable repeated automation; keep ad-hoc evaluation prompts out of runtime scripts. 6. Write the `SKILL.md` as a router. Put trigger conditions in frontmatter `description`, keep the body short, and route detailed rules to first-hop references. 7. Valid

What does the harness-skill-creator skill do?
Use when bootstrapping or tightening the smallest harness-oriented skill from an existing repository, workflow, evaluation corpus, or harness-analysis chain. Trigger for meta skills, reusable harness workflows, Qoder/Codex plugin skill sets, skill blueprints, and harness-analysis-like skills that need evidence-backed references, validation gates, and qodercli forward-tests.
How do I install it?
Run `npx skills add QoderAI/better-harness --skill harness-skill-creator --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From QoderAI/better-harness, a repository with 1,619 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
