The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 7e32a99

Skill-guided output swapped generic black-on-white boxes for a full brand system in one pass: roughness-2 dotted rectangles, solid roughness-1 arrows, Virgil font, periwinkle #8182C1 accents, and semantic stroke colors per node type (agent vs. process vs. success) — the baseline JSON had none of that structure.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Excalidraw Diagram does

Produces Excalidraw diagram JSON files for architecture maps, agent pipelines, and client deliverables, enforcing a specific sketchy/dotted visual language (roughness, Virgil font, periwinkle accent, semantic node colors) instead of default flowchart output. Triggers on 'draw a diagram', 'make an excalidraw', 'visualize this system', 'map this architecture'.
