Generating Figma Design

Overview

Unified make flow: CSpec → scene graph → compiler → Figma execute → screenshot → verify. Replaces the legacy spec → design → review cycle with a single compiler-driven action. All tokens resolve against the knowledge base; all Figma API rules are enforced by the compiler.

When to Use

Invoke when the user:

• says make, design, create, build, generate, or asks for a "new component" / "new screen"
• has already run setup (knowledge base exists)
• has an MCP transport available (console or official)

Do NOT use if:

• the user is adjusting an existing design that is already in Figma — use learning-from-corrections instead
• the user is archiving or shipping — use shipping-and-archiving
• the knowledge base is missing — run extracting-design-system first

Procedure

Before starting, load:

• references/compiler-reference.md (repo-root) — scene graph JSON format and rules
• references/transport-adapter.md (repo-root) — transport detection and tool mapping

Prerequisites

• Knowledge base exists (registries populated) — if not: "Run setup first"
• MCP transport available (see references/transport-adapter.md (repo-root) Section A)

---

Phase A — Context (target: 30s)

A1. Detect transport

Read references/transport-adapter.md (repo-root) Section A. Determine console vs official transport.

Console: figma_get_status() -> setup.valid: true
Official: whoami() + test use_figma call

Report:

Transport: {console | official}

A2. Load registry index

Load the summary of available DS components — names and types only, not full registry data:

• registries/components.json — extract component names, variant property names, and keys
• registries/variables.json — extract variable name paths (for token reference validation)
• registries/text-styles.json — extract style names (for $text/ reference validation)
• registries/icons.json — extract icon names (if file exists)
• registries/logos.json — extract logo names (if file exists)

Do NOT load guides, patterns, or figma-api-rules.md. The compiler handles all Figma API rules.

A3. Load learnings

Load knowledge-base/learnings.json (skip if file doesn't exist).

Filter by context matching the user's description:

• Include all global learnings (scope: "global")
• Include contextual learnings where context.screenType or context.component matches

A4. Load recipe index

Load knowledge-base/recipes/_index.json (skip if file doesn't exist — no recipes yet).

---

Phase B — Recipe Match

B1. Extract archetype

From the user's description, identify:

• Mode: component or screen (ask if ambiguous)
• Archetype: screen type (settings, dashboard, form, detail, list...) or component type
• Keywords: key terms from the description (sidebar, form, table, cards, navigation...)

B2. Score against recipe index

For each recipe in _index.json, compute a match score:

Dimension	Weight	Method
Archetype match	0.40	Exact match on meta.archetype vs extracted archetype
Tag overlap	0.25	Jaccard similarity between recipe tags and extracted keywords
Structural match	0.20	Zone count, component types, parameter compatibility
Confidence	0.15	Recipe's current confidence score

B3. Apply match result

Score	Action
>= 0.85	Exact match. Load recipe file, pre-fill CSpec from recipe parameters. Report: "Recipe match: {name} (score: {score}). Using as template."
0.60 -- 0.84	Partial match. Load recipe as scaffold. Report: "Partial recipe match: {name} (score: {score}). Using as starting point, will supplement missing zones."
< 0.60	No match. Proceed from scratch. Report: "No recipe match. Generating from scratch."

---

Phase C — CSpec (target: 30-60s)

C1. Generate CSpec YAML

Choose the appropriate template:

• Screen mode: skills/generating-figma-design/references/templates/screen-cspec.yaml
• Component mode: skills/generating-figma-design/references/templates/component-cspec.yaml

Fill the CSpec based on:

• User description (intent, sections, components)
• Recipe template (if match found in Phase B)
• Registry data (available components, tokens, text styles)

If a recipe was matched (>= 0.60):

• Start from the recipe's graph structure
• Replace {{ param }} placeholders with values from the user's description
• Resolve @lookup:ComponentName references against the live registry
• Add/remove zones as needed for the specific request

If no recipe match (from scratch):

• Build the layout tree node by node using the CSpec template structure
• Reference DS components as INSTANCE nodes (by name — the compiler resolves keys)
• Use $token references for all spacing, colors, radius, typography
• Use REPEAT nodes for lists/grids with repeated structure

C2. Apply learnings

Integrate learnings from A3 into the CSpec:

• Global learnings (scope: "global"): auto-apply — replace default token values with learned preferences
• Contextual learnings (scope: "contextual"): suggest — note in comments, apply if context matches

Report applied learnings:

LEARNINGS APPLIED ({n}):
- {rule} (signals: {n}, scope: {scope})
- {rule} (signals: {n}, scope: {scope})

C3. Detect new DS components (screen mode only)

For each UI pattern described in the CSpec, check if it exists in the component registry:

• If covered by an existing DS component -> use INSTANCE node
• If NOT covered -> add to new_components section of the CSpec

If new components are identified:

{N} new DS component(s) needed:
1. {name} — {description}

These must be created before this screen. Starting with: {name}

-> Trigger a nested make flow for each new component. When all are done, resume the screen make.

C4. Present plan to user

Show a readable summary of the CSpec (NOT raw YAML). Format as a plan tree:

PLAN: {name}
Mode: {screen | component}
Canvas: {1440px (web) | 390px (mobile) | 1024px (tablet)}
Recipe: {recipe name or "from scratch"}
Learnings: {n} applied

STRUCTURE:
  Root ({width}x{height}, {layout direction})
  +-- {Zone 1} ({width}, {layout})
  |   +-- {Component} ({variant})
  |   +-- {Component} ({variant})
  +-- {Zone 2} ({fillH}, {layout})
  |   +-- {Section 1}
  |   |   +-- {Component} ({variant})
  |   +-- {Section 2}
  |   |   +-- REPEAT x{n}: {Component}

DS COMPONENTS: {n} instances
TOKENS: {n} references
STATES: {list or "populated only"}

Generate this design?

C5. User validates

Wait for explicit user confirmation. The user can:

• Approve -> proceed to Phase D
• Adjust -> modify the CSpec based on feedback, re-present plan
• Cancel -> abort

C6. Save CSpec

Save the CSpec YAML to specs/active/{name}.cspec.yaml.

---

Phase D — Compile + Execute

D1. Convert CSpec to scene graph JSON

Transform the CSpec's layout tree into the scene graph JSON format defined in references/compiler-reference.md (repo-root):

• CSpec layout nodes map directly to scene graph nodes
• All $token references are preserved (the compiler resolves them)
• Component names in INSTANCE nodes are preserved (the compiler resolves keys)
• REPEAT and CONDITIONAL nodes pass through to the compiler

Add the root wrapper:

{
  "version": "3.0",
  "metadata": {
    "name": "{CSpec meta.name}",
    "width": {CSpec meta.width},
    "height": {CSpec meta.height},
    "transport": "{detected transport}",
    "fileKey": "{user's file key}"
  },
  "fonts": [ ... ],
  "nodes": [ ... ]
}

Font list: Collect all unique font families and styles referenced by $text/ tokens in the scene graph. Cross-reference against registries/text-styles.json to get actual font family + style values.

D2. Write scene graph to temp file

# Write JSON to temp file
cat > /tmp/bridge-scene-{name}.json << 'EOF'
{ ... scene graph JSON ... }
EOF

D3. Run the compiler

bridge-ds compile \
  --input /tmp/bridge-scene-{name}.json \
  --kb {kb-path} \
  --transport {console|official}

The compiler outputs a JSON array of { id, code, description } chunks to stdout.

D4. Handle compiler errors

If the compiler returns errors to stderr:

1. Read the error messages and suggestions
2. Fix the scene graph JSON based on the suggestions (see references/compiler-reference.md (repo-root) Section 8 for common errors)
3. Re-write the temp file and re-run the compiler
4. Maximum 3 attempts. If still failing after 3, report errors to user and ask for guidance.

D5. Execute chunks in Figma

For each output chunk from the compiler:

Console transport:

figma_execute({ code: "{chunk.code}" })

Official transport:

use_figma({
  fileKey: "{fileKey}",
  description: "{chunk.description}",
  code: "{chunk.code}"
})

Execute chunks sequentially. If a chunk fails:

1. Read the error
2. Report to user
3. Attempt fix if the error is clear (e.g., font not loaded, component not found)

D6. Take screenshot

Take a screenshot AFTER the final chunk (not after each chunk):

Console: figma_take_screenshot({ node_id: "{rootNodeId}", file_key: "{fileKey}" })
Official: get_screenshot({ nodeId: "{rootNodeId}", fileKey: "{fileKey}" })

D7. Save snapshot

Save a snapshot of the design's node tree for future fix diffing.

Run a node tree extraction script via figma_execute (or use_figma), using the root node ID from D5.

Save to specs/active/{name}-snapshot.json:

{
  "meta": {
    "spec": "{name}",
    "generatedAt": "{ISO timestamp}",
    "rootNodeId": "{rootId}",
    "fileKey": "{fileKey}",
    "recipe": "{recipe ID or null}",
    "learningsApplied": ["{learning IDs}"]
  },
  "tree": { ... extracted node tree ... }
}

---

Phase E — Present

E1. Show screenshot

Display the screenshot taken in D6.

E2. Report

Design compiled and executed.

File: {figma_url}
Created:
  - {n} component instances
  - {n} bound variables (colors + spacing + radius)
  - {n} learnings applied
  - Recipe: {recipe name or "from scratch"}
  - Chunks: {n} executed

Warnings:
  - {any issues}

E3. Offer next step

Looks good? Options:
  - Describe changes -> I'll modify and recompile
  - "I adjusted in Figma" -> triggers fix flow
  - "done" / "ship it" -> triggers done flow

---

Iteration Loop

User describes changes (in conversation)

1. Identify which parts of the scene graph need modification
2. Update the scene graph JSON (modify affected nodes only)
3. Re-write temp file
4. Re-run the compiler
5. Execute only the affected chunks (not the entire design)
6. Take new screenshot
7. Update snapshot
8. Present result and offer next step again

User says "I adjusted in Figma"

Trigger the fix flow via the learning-from-corrections skill.

User says "done" / "ship it"

Trigger the done flow via the shipping-and-archiving skill.

---

Target Turn Budget

Turn	Action
1	Phase A (context load) + Phase B (recipe match)
2	Phase C (CSpec generation, present plan to user)
3	User confirms or adjusts
4	Phase D (compile + execute all chunks)
5	Phase E (screenshot, report, offer next step)
6+	Iteration loop (if changes requested)

Target: 5 turns for a first-pass generation. Each iteration adds 2-3 turns.

---

Compiler vs Raw Scripts

In v3, Claude NEVER writes raw Figma Plugin API scripts. The workflow is:

Claude produces scene graph JSON
  -> Compiler resolves tokens, validates structure, generates code
  -> Code chunks are executed via MCP

NOT:
  Claude writes figma_execute scripts directly

This means:

• No need to load figma-api-rules.md
• No need to remember FILL-after-appendChild, resize-before-sizing, etc.
• No pre-script element audits (the compiler validates against registries)
• No script line counting or splitting logic
• Errors are caught by the compiler with actionable suggestions

The only time Claude touches raw Plugin API code is:

1. Snapshot extraction scripts (small, standardized)
2. Emergency fixes when the compiler cannot handle an edge case (rare)

Every Figma execution MUST pass Gate A (compile) before execute and Gate B (visual) before claiming the iteration is complete. See `references/verification-gates.md` (repo-root).

NEVER write raw Figma Plugin API code. All scene graphs go through lib/compiler/compile.ts (shipped as bridge-ds compile).

NEVER use hardcoded primitive values in the scene graph. Only $token references.

Red Flags

See the full catalog at references/red-flags-catalog.md (repo-root).

Top flags for this skill:

• "I'll hardcode this hex once, it's faster" → Always use a semantic token.
• "The compiler is overkill for this tiny thing" → The compiler is the only path.
• "I remember this nodeId from my last session" → NodeIds are session-scoped, re-search.

Verification

This skill is gated by references/verification-gates.md (repo-root):

• Gate A (Compile) — mandatory before any figma_execute / use_figma.
• Gate B (Visual) — mandatory at the end of each iteration. Fresh screenshot in this turn + user confirmation.

Evidence to surface: compiler stdout, scene graph JSON, screenshot tool result, user confirmation text.
