Located the skill at .factory/skills/add-new-opc-skill/SKILL.md — not under skills/, and absent from both skills.json and .claude-plugin/marketplace.json, so it is a repo-internal maintainer skill installable only by manual copy. Frontmatter has name+description; I raw-fetched 4 referenced files and all returned HTTP 200 (template/SKILL.md, skills/nanobanana/scripts/batch_generate.py, skills/logo-creator/scripts/vectorize.py, website/worker.js), and found no curl|sh, base64 blobs, secret exfiltration or injection text. Task: produce the complete edit set for a new skill `pdf-extract` — my baseline covered 2 surfaces (skills.json partially, README) and got the entry shape wrong (1 install string instead of 9, missing logo/auth/dependencies/commands/links), while the skill-followed pass covered 6 surfaces plus a verification block and the develop-branch PR flow. Two real defects found by checking against the live repo: step 5 says to edit `fetchCompareData()` in website/worker.js and that function does not exist (the hardcoded array is in `getFallbackConfig()` at line 1383, and a second hardcoded llms.txt skill list near line 145 is never mentioned and has already drifted — `archive` is missing from it), and the checklist omits skills/<name>/.claude-plugin/plugin.json plus the marketplace.json plugins array that 9 of 10 existing skills have. Caveat on method: I had to read the body to test it, so the baseline is a reconstruction of repo-inspection-only output, though the coverage gaps it shows are verifiable facts about the repo.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 4/5
- Triggers reliably 4/5
- Output vs. baseline 6/10
- Docs & honesty 3/5
What Add New Opc Skill does
A contributor checklist for the ReScienceLab/opc-skills monorepo that walks through creating the skill directory from the repo template, generating a pixel-art SVG logo, adding the full skills.json entry, and updating README.md, website/worker.js and CHANGELOG.md, then verifying each surface with shell commands before opening a PR against develop. It triggers when adding, publishing, or preparing a skill for release in that specific repo. It is useful only to maintainers and contributors of opc-skills and has no value in an unrelated project.
How to install Add New Opc Skill
# Not published in skills.json or the plugin marketplace, so `npx skills add ... --skill add-new-opc-skill` does NOT work.
git clone https://github.com/ReScienceLab/opc-skills.git
mkdir -p ~/.claude/skills/add-new-opc-skill
cp opc-skills/.factory/skills/add-new-opc-skill/SKILL.md ~/.claude/skills/add-new-opc-skill/
# Run it with cwd = the opc-skills repo root; every path in the body is repo-root-relative.
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.
