Stitch Enhance Prompt
This skill is a catalog-normalized import from https://github.com/google-labs-code/stitch-skills at commit 7b53207b94e62911777d53d4238b5f8c88c2b519, source path plugins/stitch-utilities/skills/enhance-prompt. The upstream control file was corrected for this workspace: the verified Stitch MCP surface here is design-system oriented, so screen lookup, screen generation, and screen editing tools must be used only when the current host explicitly exposes them.
When to Use This Skill
- Use when a rough Stitch prompt needs better structure or an edit prompt needs precision.
- The task involves Google Stitch project IDs,
.stitch/artifacts, DESIGN.md files, Stitch exports, or Stitch-specific validation. - The broader
stitch-designrouter points here as the narrowest workflow.
Workflow
- Identify platform, page type, intent, sections, visual style, components, and constraints already present.
- Read
.stitch/DESIGN.mdwhen present and include only relevant rules. - Replace vague terms with concrete UI patterns, component names, and layout structure.
- For generation prompts, describe layout, content, and behavior without duplicating project-level theme tokens.
- For edit prompts, name the exact screen region and focused change.
- Return the enhanced prompt plus assumptions that affect the design.
Local Assets
examples/,resources/,references/, orreference/are upstream support material when present. TreatSKILL.mdas the source of truth if a support file mentions an unavailable MCP tool.scripts/are optional helpers. On Windows, prefer PowerShell or Node equivalents unless Git Bash or WSL is actually available.- Keep generated
.stitch/files out of commits unless the user explicitly wants them as durable examples.
Corrected Stitch MCP Surface
Verified in this workspace on 2026-06-15: create_project, upload_design_md, create_design_system_from_design_md, list_design_systems, and apply_design_system. This 2026-07-29 source refresh did not re-verify a broader live MCP surface. Do not claim list_projects, list_screens, get_project, get_screen, generate_screen_from_text, edit_screens, or generate_variants were used unless the current host exposes those exact tools in the active tool list.
Anti-Patterns
- Claiming a Stitch screen-generation, screen-editing, or screen-retrieval MCP call succeeded when the active host does not expose that tool.
- Uploading files, screenshots, HTML, markdown, or design assets to Stitch without user-approved destination and artifact details.
- Reading, printing, storing, or committing Stitch API keys, MCP config secrets, cookies, or credential-bearing files.
- Treating generated design or code as final without local render, syntax, or artifact verification.
- Collapsing this workflow into a broader frontend/design skill when Stitch-specific files, project IDs, or design-system assets matter.
Verification Protocol
Before claiming this skill was applied successfully:
- Pass/fail: Output includes platform, purpose, page structure, and component terms.
- Pass/fail: It preserves user intent instead of over-designing a different product.
- Pass/fail: Design-system context is included only when useful.
- Pass/fail: The prompt is ready for Stitch generation or web UI use.
- Pressure-test scenario: Repeat the workflow with Stitch MCP screen tools unavailable and confirm the fallback path remains honest and actionable.
- Success metric: The user can identify the exact artifact, project/design-system target, and verification evidence without relying on unstated MCP behavior.
Cross-Client Portability
This skill is written to stay usable across GitHub Copilot, Claude Code, and Codex.
- GitHub Copilot: keep the folder in a Copilot-visible skill path or wrap the workflow in project instructions when folder discovery is unavailable.
- Claude Code: keep the folder in a local skills directory or a compatible plugin source.
- Codex: install or sync the folder into
$CODEX_HOME/skills/stitch-enhance-promptand restart Codex after major changes.
MCP Availability And Fallback
Preferred MCP Server: Stitch MCP
- Fallback prompt: "Use the Stitch Enhance Prompt skill without Stitch MCP. No MCP is required; use local DESIGN.md files, prompt references, and user context. Show the exact files, commands, manual Stitch UI steps, and verification evidence used before concluding."
- Verified Stitch MCP tools in this workspace are design-system/project oriented; use broader screen tools only when the current host exposes them.
- Use local scripts, exported HTML/screenshots, the Stitch web UI, and project metadata files as the fallback evidence path.
