Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

claude-canvas CLAUDE.md 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 yesterday.

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.

claude-canvas — AI-Orchestrated Visual Production

This is a Claude Code plugin for creating, populating, and laying out Obsidian Canvas files with AI assistance.

What It Does

Claude acts as Creative Director for Obsidian Canvas. Describe what you want — a presentation, mood board, flowchart, or knowledge graph — and get a fully populated, professionally laid-out canvas with AI-generated images, diagrams, and text.

Quick Commands

You say Claude does
/canvas List canvases with node counts
/canvas create my-project Create a new canvas
/canvas add image photo.png Add an image node
/canvas add banana "hero image" Generate AI image, add to canvas
/canvas layout dagre Re-layout with hierarchical algorithm
/canvas present "Q3 Review" Build a presentation canvas
/canvas generate "mood board for game" Full AI-orchestrated generation
/canvas template list Browse 12 archetypes

Canvas Location

  • If wiki/canvases/ exists (claude-obsidian vault): uses that
  • Otherwise: creates .canvases/ in the current project directory

Integration

Works with /banana (AI images), /svg (diagrams), /claude-gif-* (animations) when installed. Gracefully degrades if not available.

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.
