implement-github-feature
Design and implement a new feature or component from a GitHub issue. Use for net-new functionality, not bug fixes.
npx skills add AgnosticUI/agnosticui --skill implement-github-feature --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.
**Usage:** `/implement-github-feature ISSUE_NUMBER` **Example:** `/implement-github-feature 281` Implement GitHub feature request $ARGUMENTS following AgnosticUI conventions, accessibility standards, and CSS-first principles. --- ## Setup 1. **Read project context** - Read `.claude/PROJECT_CONTEXT.md` - Understand: - Repository structure - Design principles - Accessibility requirements - Branch conventions - Component workflows --- ## Phase 0: Safety Checks (Required) 2. **Verify clean starting state** - Run `git status` - Confirm: - Working directory is clean - Current branch is `master` - If either condition fails: - **STOP** - Ask the user to resolve before continuing --- ## Phase 1: Branching 3. **Propose feature branch** - Follow convention: `issue-$ARGUMENTS/short-descriptive-name` - Example: `issue-281/selection-card-group` - Run: ``` git checkout -b issue-$ARGUMENTS/short-description ``` - **WAIT FOR USER APPROVAL of branch name before proceeding** --- ## Phase 2: Issue Analysis & Intent Extraction (No Code) 4. **Analyze the GitHub issue** - Fetch full details: ``` gh issue view $ARGUMENTS ``` - Extract and summarize: - Feature goals - Non-goals / constraints - API expectat

What does the implement-github-feature skill do?
Design and implement a new feature or component from a GitHub issue. Use for net-new functionality, not bug fixes.
How do I install it?
Run `npx skills add AgnosticUI/agnosticui --skill implement-github-feature --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 AgnosticUI/agnosticui, a repository with 822 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.
