description	Minimal Excalidraw workflow for stable output. Steps: start session first, route Mermaid/manual inputs correctly, use the default Ghibli style, write in small batches, and verify.

Excalidraw Drawing (Minimal)

Use this skill for fast, stable diagram output with minimal process overhead.

Source of truth: this file is the primary definition.

Tools

• start_session
• create_from_mermaid
• add_elements
• update_element
• get_scene

Rules

1. Always call start_session first for the target sessionId.
2. Strategy routing:

• Mermaid input (```mermaid block or Mermaid DSL) -> create_from_mermaid
• Non-Mermaid input -> add_elements / update_element

3. Use segmented writes for medium/large diagrams (2-4 batches).
4. Prefer updating by id.

Default Style

When user does not specify style, use Ghibli:

• Primary: #f0f9ff / #0369a1
• Secondary: #f7fee7 / #365314
• Accent: #fff7ed / #9a3412
• Shared: fillStyle: "hachure", roughness: 2, roundness: { "type": 3 }

If user specifies style, follow user style.

Workflow

1. start_session(sessionId)
2. First render:

• Mermaid -> create_from_mermaid
• Manual -> add_elements (segmented)

3. Quick polish with update_element
4. Verify with get_scene

Quick Verification

• get_scene succeeds
• key nodes/edges exist
• labels are readable on core nodes
• no obvious broken connector on core flow

If checks fail, fix only the affected region and re-check.

Completion Output

Report:

1. sessionId
2. created/updated ids
3. verification pass/fail
