Figma to Mobile

Convert Figma designs to mobile UI code with interactive clarification.

Supported: Android Compose, Android XML, iOS SwiftUI, iOS UIKit.

Prerequisites

• FIGMA_TOKEN environment variable set (Figma > Settings > Personal Access Tokens) ⚠️ Your Figma token is sensitive — treat it like a password. Never paste it into chat messages (they may be logged). Set it via your shell rc file or OpenClaw env config.
• Python 3.8+ with requests package

Trigger & Input

This skill activates when a user explicitly asks to convert a Figma design to mobile UI code and provides a Figma link. It does NOT activate on casual mentions of Figma links, pasted URLs in logs, or design references without a conversion request.

The user may also include inline hints alongside the link, such as:

• Target platform: "Android XML", "Compose", "SwiftUI", "UIKit"
• Layout preferences: "use ConstraintLayout", "prefer StackView"
• Component notes: "the switch is our custom CompactSwitch", "this is a dynamic list"
• Any other context about the design

If the user provides hints, respect them and skip the corresponding questions. For example, if the user says "Android XML, the 3 cards are a RecyclerView list", do NOT ask about output format or whether the cards are dynamic/static.

Not Applicable

This skill is NOT for:

• Screenshot / image → code: it works only with Figma design links via the Figma REST API, not with screenshots or image files.
• Layout code without a Figma link: generic "write me a login screen" requests have no design to interpret.
• Casual mentions or pasted URLs without a conversion request — see Trigger & Input above.
• Pure design discussion or Figma feature questions: no code is generated.

Deliverables

After a successful conversion, the user receives:

• Generated UI code files — platform-idiomatic (Compose / XML / SwiftUI / UIKit / Flutter). Multiple files are presented with a clear filename header (see Step 3).
• scan-report.json — project resource scan results, only when the user agrees to a project scan (Step 2.5).
• feedback-log.md — correction log written to the project root, only with user consent (Step 4).

Workflow

Step 1: Fetch & Analyze

When user provides Figma link(s):

1. Determine the input type:

   A. Link without specific node-id (no node-id, or node-id=0-1): This link points to the entire page, not a specific frame. Tell the user:

   This link points to the whole page. Please select the frame you want in Figma, right-click it, and choose "Copy link to selection", then send that link. If you want to convert multiple frames, send multiple links.

   B. Single frame link (has specific node-id):

   python scripts/figma_fetch.py "https://www.figma.com/design//?node-id="
   

   → returns that frame's design data. Proceed to analysis.

   C. Multiple links (user sends 2+ URLs): Determine the relationship by frame names and user context: same-page states → --compare mode (multi-state code); parent+overlay → independent layout files; independent pages → fetch one at a time, ask which to convert first. If unsure, ask the user.

   Detailed multi-frame rules: Read references/multi-frame.md

2. If the link has no specific node-id, ask the user to re-copy from the specific frame (see A above). Do NOT call the API.

3. Analyze the structure: identify sections, repeated patterns, component types

4. Note INSTANCE nodes — they indicate reusable components. Check variantProperties for component state (e.g. State=Default, Size=Large) — these map to multi-state code

5. Note gradient/shadow data — flag for the user if complex

6. Apply Figma node interpretation rules before generating code

Detailed interpretation rules: Read references/figma-interpretation.md

Step 1.5: Structure Summary

Before asking any questions, present a brief structure summary to the user so they can confirm your understanding:

I see: [navigation bar with back button + title] → [2 content sections: user profile card, settings list (8 items)] → [bottom action button]. Total ~25 nodes.

Keep it to 2-3 lines. Mention:

• Major sections identified (nav bar, content areas, footer)
• Repeated patterns ("8 similar list items", "3 tab labels")
• Notable elements (gradients, complex illustrations, stacked cards)

If the user says "that's wrong" or corrects the structure, adjust understanding before proceeding to Step 2.

If the design has ≤10 leaf nodes (visible elements that map to actual views), skip this step — the structure is simple enough to proceed directly.

Step 2: Confirm & Clarify

Question priority (strict order — ask earlier questions first):

1. Output format (MUST ask first unless user already specified) → Android XML / Compose / SwiftUI / UIKit This determines all subsequent analysis phrasing and code output.

2. Structural ambiguities (only ask what you're genuinely unsure about) → "These N items look similar — dynamic list or fixed layout?" → "This area: single image asset or icon-on-background combo?"

3. Component choices (only if platform-relevant) → "Any custom components to use? (otherwise I'll use platform defaults)"

Rules for questions:

• Skip any question the user already answered via inline hints
• Max 3-5 questions total, fewer is better
• Each question gives concrete options with one-line pros/cons
• Every question includes an open option: "or tell me more about this"
• Use natural language, no JSON or technical dumps
• If everything is clear (user gave full context + simple structure), skip Step 2 entirely

Confidence guide — when to ask vs. when to just generate:

• ≥3 sibling nodes with similar structure → likely a list → ASK (dynamic vs static)
• INSTANCE nodes sharing same componentId → reusable component → MENTION but can default
• Single clear hierarchy, no ambiguity → high confidence → SKIP questions, go to Step 3
• Gradient/complex shadow in design → MENTION in summary ("I see a gradient here, I'll approximate it as X")

Step 2.5: Project Scan — Ask First

⚠️ Always ask the user before scanning their project. Scanning reads local files; the user should know and agree.

"你的项目在 /path/to/project 对吗？要不要我先扫描一下项目里已有的资源 （颜色、文案、图片、自定义组件），这样生成代码时可以直接复用已有的东西？"

If the user agrees:

python scripts/project_scan.py /path/to/project --json --output scan-report.json

Then read scan-report.json and references/scan-usage.md.

If the user declines: proceed with hardcoded values per generation rules.

How to present scan results (with sample phrasing): Read references/scan-usage.md

If no project path is known yet, don't scan. Proceed with hardcoded generation.

Step 3: Generate Code

After user confirms (or if no questions needed), generate code files.

Detailed generation rules: Read references/generation-rules.md

If multiple files are needed, output each with a clear filename header:

📄 activity_notification_settings.xml
[code]

📄 item_expert_notification.xml
[code]

Step 4: Iterate & Capture Feedback

After showing code, ask briefly:

Matches the design? Any adjustments?

The user can then give feedback to refine the output. Common iterations:

• "间距大了" → adjust specific spacing
• "Switch 换成我们的 CustomSwitch" → swap component
• "把标题栏去掉" → remove section
• "换成 Compose 版本" → regenerate in different format
• "颜色不对，这里应该是 #333333" → fix specific values

Continue iterating until the user is satisfied.

Iteration output rule:

• If the file has already been written to disk → read the current file, apply only the minimal patch, output just the changed lines with clear context (file path + line range). Do NOT regenerate the whole file.
• If the code only exists in the conversation (not written to disk) → output only the changed snippet with a comment indicating where it replaces (e.g., // replaces lines 12-18 in activity_main.xml). Do NOT repeat the entire file.
• Only regenerate the full file if the user explicitly asks (e.g., "重新生成完整文件", "show me the full file").

⚠️ Before logging any feedback, tell the user:

"I'll save this correction locally to feedback-log.md to improve future output. It stores before/after snippets — is that OK?" Only proceed if the user agrees.

⚠️ IMPORTANT: Every time the user corrects your output (layout issue, wrong component, spacing problem, etc.), you MUST log it to feedback-log.md before proceeding with the fix (after user consent). Do not skip this step — the log is how the skill learns and improves over time.

API Request Limits

The bundled scripts/figma_fetch.py enforces these limits automatically:

• Timeout: 30s per request
• Retries: up to 3 attempts on connection/SSL errors (backoff 5s/10s/15s)
• Rate limit: ≥2s between requests; on HTTP 429, wait per Retry-After header (cap 30s)
• Adaptive depth: refetches with deeper depth (up to 15) when children look truncated

When a rate limit is exceeded, the script reports:

{
  "status": "error",
  "error": "RATE_LIMIT_EXCEEDED",
  "message": "Figma API rate limit exceeded",
  "retry_after_seconds": 30,
  "plan_tier": "FREE",
  "limit_type": "requests_per_minute"
}

Error Handling

Quick reference — full details in references/error-handling.md:

• FIGMA_TOKEN not set (FIGMA_TOKEN_NOT_SET) → guide user to set env var; never paste token into chat
• 403/401 → token expired/revoked; regenerate in Figma Settings → Security
• Invalid URL → show valid format: https://www.figma.com/design//?node-id=
• API error / node too large / depth auto-increased → see references/error-handling.md

Tips

• Token safety: never paste FIGMA_TOKEN into chat — set it as an environment variable (see Prerequisites).
• Rate limits: keep ≥2s between Figma API calls; the script enforces this, so avoid parallel fetches to save time.
• Multi-frame: compare shared components across frames before generating code to avoid duplication.
