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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00072 | $0.01280 |
| Opus 5 | $0.00036 | $0.00640 |
| Sonnet 5 | $0.00014 | $0.00256 |
| Haiku 4.5 | $0.00007 | $0.00128 |
Grade A, and why
canvas scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Canvas
Treat a canvas as a vault-scoped JSON Canvas document. Keep reads read-only and route every requested mutation through one recoverable transaction.
Resolve the installed product root from this skill's own location, not from the vault or current working directory:
PRODUCT_ROOT=/absolute/path/to/installed/claude-obsidian
CORE="$PRODUCT_ROOT/scripts/claude-obsidian.py"
test -f "$CORE"
Choose the syntax source
Prefer a separately installed kepano/obsidian-skills json-canvas skill for
format details. Otherwise read references/canvas-spec.md.
The open standard is JSON Canvas 1.0.
Use this skill for vault workflow and transaction safety even when an upstream syntax skill is available.
Scope
- Resolve the user vault before reading. Never derive it from plugin files.
- Store boards under
wiki/canvases/; usewiki/canvases/main.canvasonly as the default when the user did not name a board. - Treat
wiki/canvases/index.mdas an optional catalog. Update it only when a canvas is created, renamed, or removed. - Use vault-relative paths in
fileandbackground; reject absolute paths,..traversal, home shortcuts, and paths that escape through symlinks. - Reference only files already inside the vault. If an optional capture or media capability is detected, compose with it and consume its returned vault-relative path. Do not assume a particular plugin, command, or session log, and do not download or copy assets in this skill.
- Use
linknodes for URLs. Accept HTTPS URLs only; a link node does not grant permission to fetch the page. Creating its JSON makes no request, but opening it in Obsidian may fetch Open Graph metadata from that URL's host. Disclose that render-time egress and confirm it is acceptable; otherwise use a text node containing the URL.
Read-only operations
For status or list requests, parse the selected .canvas files and report node
counts, group labels, broken edge endpoints, and missing vault-relative file
targets. If the default canvas is absent, report that fact and offer a creation
preview; do not create it during a status request.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

canvas is a skill published in the GitHub repository AgriciDaniel/claude-obsidian (14,464 stars, last pushed 6d ago), licensed MIT. It adds 72 tokens to every session and 1,280 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
