Authoring Stitch Prompts

Authoring Stitch Prompts

Quick Start

1. Collect context – accept natural language, specs, or referenced files describing the screen/app.

1.5. Discover design context (optional) – check for design-intent/:

• If exists: Extract Project Type, Design System from design-intent/memory/constitution.md
• If not found: Scan codebase for framework hints (package.json)
• Falls back gracefully to standalone mode
• See [WORKFLOW.md](WORKFLOW.md#05-design-context-discovery-optional-enhancement) for details.

1. Parse essentials – identify app type, screen focus, layout elements, and visual cues.
2. Detect split points – analyze if input contains multiple screens or distinct intents (>2). Apply smart defaults: split if >2 screens/intents, else combine. Users can request regeneration with different approach.
3. Filter aggressively – strip ALL non-UI concerns (backend, auth, APIs, caching, error handling, performance metrics, code-level specs). Focus EXCLUSIVELY on visual layout, components, colors, typography, spacing, and interaction patterns.
4. Condense – rewrite into one atomic Stitch directive using "Design/Create/Add…" phrasing.
5. Structure output – follow the Stitch prompt template (directive sentence → bullet list → 3–6 style cues → constraints). If design context was discovered, inject project-appropriate style cues. Do NOT use multi-section headings.
6. Validate – ensure UI nouns are present, word count 6 prompts, split into prompt-v{version}-part{N}.md files (max 6 per part)

• Copy-paste ready: Entire file works directly in Stitch interface

See [WORKFLOW.md](WORKFLOW.md#35-generate-layout-prompt-if-detected) for detailed file composition rules, [REFERENCE.md](REFERENCE.md) for Stitch best practices, and [EXAMPLES.md](EXAMPLES.md) for worked examples (Examples 14–16 cover multi-component and split scenarios).

Input Types

Accepted

• Natural-language descriptions (single screen or short flows)
• Markdown/YAML/JSON specs (/specs/dashboard.md)
• Revision directives ("move KPI cards above chart", "convert to French", "change button to green")
• References to uploaded wireframes or images
• Language conversion requests ("switch to Spanish", "German version")
• Structured input from /prompt command (see below)

---

Structured Input (from /prompt command)

When invoked via /prompt, the skill may receive pre-parsed preferences (Brief, Components, Style, Structure). Parse structured fields and apply style mappings before proceeding. See [WORKFLOW.md](WORKFLOW.md#08-parse-structured-input-if-present) for field handling and style mapping tables.

All input detail levels are valid — Stitch infers patterns from minimal descriptions. Use adjectives to convey vibe when details are sparse ("vibrant fitness app", "minimal meditation app").

Workflow Overview

High-level loop: parse → condense → format → validate. Detailed branching logic, including cue extraction and revision handling, lives in [WORKFLOW.md](WORKFLOW.md).

---

Output Structure

Prompts must follow the Stitch-friendly template:

• One-sentence description of the app/screen + primary intent.
• Bullet list (3–6 items) covering layout, components, or flows.
• Visual style cues (palette, typography, density, tone).
• Optional behavior/constraint reminders (responsiveness, export format).

Reference [templates/authoring-stitch-prompts-template.md](templates/authoring-stitch-prompts-template.md) for wording patterns and [templates/layout-prompt-template.md](templates/layout-prompt-template.md) for layout/foundation prompts.

Examples

Representative before/after samples (SaaS dashboard, banking app, iterative edits, spec conversions) are in [EXAMPLES.md](EXAMPLES.md). Use them to mirror tone and formatting; keep this file lean by not re-embedding the full transcripts here.

Design Context Integration

When design-intent/ exists in the project, the skill enhances style cues with project context:

• Project Type influences tone (e.g., "enterprise-grade" for Enterprise, "friendly, approachable" for Consumer)
• Design System names appear in style cues (e.g., "Fluent UI styling", "Material Design patterns")

The skill does NOT inject specific tokens (hex colors, spacing values)—only high-level descriptors that help Stitch generate contextually appropriate designs.

Fallback behavior: If design-intent/ is not found, the skill works standalone using default style cues.

See [WORKFLOW.md](WORKFLOW.md#05-design-context-discovery-optional-enhancement) for discovery logic and [WORKFLOW.md](WORKFLOW.md#37-inject-design-context-into-style-cues) for injection rules.

---

MCP Integration (Optional)

When @_davideast/stitch-mcp is configured, prompts can be sent directly to Stitch for generation after authoring.

With MCP: Author prompt -> Generate screens -> Fetch images/code Without MCP: Author prompt -> Copy to Stitch manually

After authoring, offer: "Stitch MCP is available. Generate screens now? [Yes / No / Just save prompts]"

If accepted, invoke the generating-stitch-screens skill with the authored prompt file.

Common Issues

• Prompts too verbose – Re-run formatting with the template and trim narration. See [TROUBLESHOOTING.md](TROUBLESHOOTING.md#prompts-are-too-verbose).
• Missing style cues – Derive palette/typography keywords from user input or prior session context before finalizing. See [TROUBLESHOOTING.md](TROUBLESHOOTING.md#missing-style-cues).
• Multi-goal briefs – Split into multiple prompts; re-emphasize Stitch's atomic focus. See [TROUBLESHOOTING.md](TROUBLESHOOTING.md#multi-screen-prompts).
