visual-qa
Visual QA checkpoint. Verifies UI changes in the extension/backend via quick smoke flows, screenshots, and console/network checks. Use when: 'visual QA', 'UI looks wrong', 'screenshot', 'verify in Chrome'.
What this skill does
# Visual QA Checkpoint
Lightweight visual smoke test for UI-facing changes.
Writes result to `.checkpoints/visual-qa.json`.
## IMPORTANT: Not for Workers on Worktrees
**This checkpoint should only be run by the conductor AFTER merging changes to main.**
Workers on git worktrees cannot run visual-qa because:
1. **Changes aren't built** - The extension/app isn't rebuilt with worktree changes
2. **No isolated browser** - Workers share the same Chrome instance
3. **Tab group conflicts** - Multiple workers fighting for tabs (especially if groups disabled)
4. **Dev server conflicts** - Multiple `npm run dev` instances on same port
**Correct workflow:**
1. Worker completes code changes and commits
2. Conductor merges to main
3. Conductor rebuilds extension/app
4. Conductor runs `/conductor:visual-qa` on main branch
## Heuristics (v1)
- If no UI-facing files changed (no changes under `extension/` and no `*.css`, `*.tsx`, `*.jsx`) → PASS (skipped).
- Otherwise → perform a quick smoke test and record PASS/FAIL.
## Workflow
### Step 1: Detect UI-facing Changes
```bash
CHANGED=$( (git diff --name-only main...HEAD 2>/dev/null || true) ; git diff --name-only 2>/dev/null || true ; git diff --cached --name-only 2>/dev/null || true )
CHANGED=$(echo "$CHANGED" | sed '/^$/d' | sort -u)
if echo "$CHANGED" | grep -qE '^(extension/)|(\.tsx$)|(\.jsx$)|(\.css$)'; then
NEEDS_VISUAL=1
else
NEEDS_VISUAL=0
fi
```
### Step 2: Tab Group Isolation (MANDATORY)
BEFORE any browser work, create YOUR OWN tab group with a random 3-digit suffix.
This is mandatory because:
- User can switch tabs at any time - active tab is unreliable
- Multiple Claude workers may run simultaneously
- Your operations target YOUR tabs, not the user's browsing
```bash
# 1. Generate random ID
SESSION_ID="Claude-$(shuf -i 100-999 -n 1)"
# 2. Create group
mcp-cli call tabz/tabz_create_group '{"title": "'$SESSION_ID'", "color": "cyan"}'
# Returns: {"groupId": 123, ...}
# 3. Open URLs into YOUR group (use returned groupId)
mcp-cli call tabz/tabz_open_url '{"url": "https://example.com", "groupId": 123}'
# 4. Always use explicit tabId from your group - NEVER rely on active tab
```
### Step 3: Run Smoke Test (if needed)
If `NEEDS_VISUAL=1`, do the quickest relevant check:
- Open the extension side panel and ensure it loads
- Trigger the affected UI path
- Check browser console for errors
- Take a screenshot for evidence
If you have Tabz MCP available, you can use it (preferred):
- `tabz_get_console_logs` (errors)
- `tabz_screenshot` (capture)
- `tabz_enable_network_capture` + `tabz_get_network_requests` (API failures)
**Always pass explicit `tabId`** - never rely on "active tab":
```bash
# Get your tab's ID from your group
mcp-cli call tabz/tabz_screenshot '{"tabId": YOUR_TAB_ID}'
mcp-cli call tabz/tabz_get_console_logs '{"tabId": YOUR_TAB_ID}'
```
If Tabz MCP isn't available, do a manual check and note it.
### Step 4: Write Checkpoint File
```bash
mkdir -p .checkpoints
cat > .checkpoints/visual-qa.json << EOF
{
"checkpoint": "visual-qa",
"timestamp": "$(date -Iseconds)",
"passed": ${PASSED},
"needs_visual": ${NEEDS_VISUAL},
"summary": "${SUMMARY}"
}
EOF
```

contribute
IncludedLocal-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".
architectural-analysis
IncludedUser-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).

Capabilities: build MCP servers, integrate external APIs, discover/execute MCP tools, manage multi-server configs, design agent-centric tools. Actions: create, build, integrate, discover, execute, configure MCP servers/tools. Keywords: MCP, Model Context Protocol, MCP server, MCP tool, stdio transport, SSE transport, tool discovery, resource provider, prompt template, external API integration, Gemini CLI MCP, Claude MCP, agent tools, tool execution, server config.

react-native-skia
IncludedDesign, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.
plaid
IncludedProduct Led AI Development — guides founders from idea to launched product. Six capabilities: Idea (discover a product idea), Validate (pressure-test the idea against fatal flaws, problem reality, competition, and 2-week MVP feasibility), Plan (vision intake + document generation), Design (translate image references into a design.md spec), Launch (go-to-market strategy), and Build (roadmap execution). Use when someone says "PLAID", "plaid idea", "help me find an idea", "product idea", "idea from my business", "idea from my expertise", "plaid validate", "validate my idea", "pressure-test", "is this idea good", "find fatal flaws", "validate the problem", "plan a product", "define my vision", "generate a PRD", "product strategy", "plaid design", "design from image", "translate image to design", "create design.md", "extract design tokens", "plaid launch", "go-to-market", "launch plan", "GTM strategy", "launch playbook", "plaid build", "build the app", "start building", or "execute the roadmap".
nextjs-framer-motion-animations
IncludedAdds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
