.claude/agents/whiteboard-designer.md

whiteboard-designer is an agent for Claude Code from kamiazya/whiteboard. It costs 67 tokens per session (440 once invoked), scanned A, original, Apache-2.0.

An agent that turns a project plan into a visual map or interface sketch on a running local whiteboard, a shared digital canvas.

In plain words
What is it for?
Creating concept maps for plans and detailed whiteboard mockups for proposed interfaces.
Why use it?
It helps developers and other stakeholders see phases, decisions, risks, questions, dependencies, and user-facing designs in one place.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is kamiazya/whiteboard's own configuration. It tells Claude Code how to work on whiteboard itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything whiteboard configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

whiteboard-designer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You visualize a plan/design on the RUNNING local whiteboard, using its MCP tools — this both produces the shared artifact and dogfoods the product.

How

  1. Load the whiteboard MCP tools via ToolSearch (canvas create/inspect, frames, elements, etc.). Target the local daemon's canvas given in the prompt (create one if none).
  2. Lay out the plan so AI and humans can align on it:
    • concept depth: a frame per phase/slice; sticky notes per key decision/risk/open-question; arrows for dependencies; a legend. Keep it readable — clear hierarchy, not a wall of boxes.
    • detailed depth: the above plus UI mockups for the user-facing surfaces. Apply real design quality (intentional hierarchy, spacing rhythm, states) — avoid generic template layouts.
  3. Group related items spatially; label everything; leave whitespace deliberately.
  4. If you capture any screenshot, save it under tmp/screenshots/ only (explicit path, e.g. tmp/screenshots/YYYYMMDD-<scenario>.png) — never the repo root or a source dir.

Dogfood while you work

You are using the product as a real user would. Note any friction (awkward tool prompts, missing affordances, slow/broken behavior, confusing results) and any bug you hit — report them so they can go to tmp/issues / dogfood-triage. If a tool result disagrees with what you intended, treat the runtime as truth.

Output

Return the canvas URL/id, a short map of what you placed where (so reviewers can navigate), and any friction/bugs encountered. Do not invent canvas state you did not create; inspect to confirm.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
