Slack's auth server does not support dynamic client registration, so a
bare {type, url} config fails in Claude Code with "Incompatible auth
server: does not support DCR" before the OAuth prompt appears.
Cowork/Desktop resolve these via the claude.ai connector directory and
don't hit this, but Claude Code does raw OAuth against the URL. The
broken entry also shadows the working claude.ai Slack passthrough
(manual > plugin > claude.ai dedup), so users lose Slack entirely.
Adds the same oauth.{clientId, callbackPort} block already present in
partner-built/slack/.mcp.json to all 12 role plugins.

Design Plugin
A design productivity plugin primarily designed for Cowork, Anthropic's agentic desktop application — though it also works in Claude Code. Helps with design critique, system management, UX writing, accessibility, research synthesis, and developer handoff. Works with any design team — standalone with your input, supercharged when you connect Figma and other tools.
Installation
claude plugins add knowledge-work-plugins/design
Commands
Explicit workflows you invoke with a slash command:
| Command | Description |
|---|---|
/critique |
Get structured design feedback — usability, visual hierarchy, accessibility, and consistency |
/design-system |
Audit, document, or extend your design system — components, tokens, patterns |
/handoff |
Generate developer handoff specs — measurements, tokens, states, interactions, and edge cases |
/ux-copy |
Write or review UX copy — microcopy, error messages, empty states, onboarding flows |
/accessibility |
Run an accessibility audit — WCAG compliance, color contrast, screen reader, and keyboard navigation |
/research-synthesis |
Synthesize user research — interviews, surveys, usability tests into actionable insights |
All commands work standalone (describe your design or paste screenshots) and get supercharged with MCP connectors.

Example Workflows
Getting Design Feedback
/critique
Share a Figma link, screenshot, or describe your design. Get structured feedback on usability, visual hierarchy, consistency, and accessibility.
Auditing Your Design System
/design-system audit
I'll review your component library for consistency, completeness, and naming conventions. Get a report with specific improvement recommendations.
Writing UX Copy
/ux-copy error messages for payment flow
Get context-appropriate copy with tone guidance, alternatives, and localization notes.
Developer Handoff
/handoff
Share a Figma link and get a complete spec: measurements, design tokens, component states, interaction notes, and edge cases.
Accessibility Check
/accessibility
Share a design or URL. Get a WCAG 2.1 AA compliance report with specific issues, severity, and remediation steps.
Synthesizing Research
/research-synthesis
Upload interview transcripts, survey results, or usability test notes. Get themes, insights, and prioritized recommendations.
Standalone + Supercharged
Every command and skill works without any integrations:
| What You Can Do | Standalone | Supercharged With |
|---|---|---|
| Design critique | Describe or screenshot | Figma MCP (pull designs directly) |
| Design system | Describe your system | Figma MCP (audit component library) |
| Handoff specs | Describe or screenshot | Figma MCP (exact measurements, tokens) |
| UX copy | Describe the context | Knowledge base (brand voice guidelines) |
| Accessibility | Describe or screenshot | Figma MCP, analytics for real usage data |
| Research synthesis | Paste transcripts | User feedback tools (pull raw data) |
