Located SKILL.md at .claude/skills/implement-github-feature/SKILL.md via the GitHub tree API and fetched it raw (HTTP 200); frontmatter parses with name+description plus an allowed-tools list and disable-model-invocation:true. Spot-checked its referenced paths: .claude/PROJECT_CONTEXT.md returned 200 and its described structure matches the repo, and v2/lib/src/components/ and v2/site/docs/components/ both appear in the recursive tree. No security smells (no curl|sh, base64, or exfiltration). I did not run the output stage: the skill is an interactive multi-phase workflow that needs a real issue number via `gh issue view`, `git checkout -b` in the cloned repo, `npm run build` in v2/lib, and WAIT-FOR-USER-APPROVAL gates at every phase — none of which I can execute here, so no artifact could be produced without fabrication.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 3/10
  • Docs & honesty 5/5

What Implement Github Feature does

A slash-command workflow (/implement-github-feature ISSUE_NUMBER) that walks through building a net-new AgnosticUI component from a GitHub issue: safety checks, feature branch, issue analysis via gh, a design-proposal gate, scaffolding, Lit-first implementation, framework integrations, docs, and a final commit. It triggers only when explicitly invoked (disable-model-invocation is set) for net-new functionality, not bug fixes. Every phase pauses for explicit user approval before writing code or committing.

How to install Implement Github Feature

git clone --depth 1 https://github.com/AgnosticUI/agnosticui.git /tmp/implement-github-feature-src
mkdir -p ~/.claude/skills
cp -R /tmp/implement-github-feature-src/.claude/skills/implement-github-feature ~/.claude/skills/implement-github-feature
# Invoke as a slash command against a checkout of the AgnosticUI repo: /implement-github-feature ISSUE_NUMBER
# disable-model-invocation: true — it is NOT auto-loaded by description; you must run the command explicitly.
# Requires: gh CLI authenticated, the AgnosticUI v2 repo checked out to operate on, and npm for `npm run build`/`npm run lint`.
# It reads .claude/PROJECT_CONTEXT.md from that repo, so it is designed to run inside the AgnosticUI checkout.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Implement Github Feature

  • /implement-github-feature Gated multi-phase workflow to build a new component from a GitHub issue in AgnosticUI

It also activates on plain-language prompts like these:

  • Implement the feature requested in issue #55
  • Build the new export option from this GitHub issue
  • Design and code the feature in issue 210

Frequently asked questions

Is the Implement Github Feature skill free?
Yes. The skill itself is free from AgnosticUI/agnosticui. SkillProof publishes the install command and an independent test verdict at no cost.
Does Implement Github Feature work with Claude Code?
We tested it with Claude Code 2.x (agent harness) on Jul 21, 2026. Verdict: Works with setup.

What is the Implement Github Feature SkillProof Score?
7.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 3/10, docs & honesty 5/5.
How do I install Implement Github Feature?
Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
Can I use Implement Github Feature with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
