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 | $0.00093 | $0.01310 |
| Opus 5 | $0.00046 | $0.00655 |
| Sonnet 5 | $0.00019 | $0.00262 |
| Haiku 4.5 | $0.00009 | $0.00131 |
Grade A, and why
canvas-present 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.

Operations
Build Presentation (/canvas present [topic])
Create a complete presentation canvas from a topic description.
Workflow:
-
Gather context: Ask the user for:
- Topic/title (required)
- Number of slides (default: 6, recommend 6-10)
- Style:
deck(1200×675 clean) orstoryboard(1920×1080 with script column) - Whether to generate images for slides (requires
/banana)
-
Generate slide structure: Claude writes the content for each slide:
- Slide 1: Title slide (title, subtitle, date)
- Slide 2: Agenda/overview
- Slides 3-N-2: Content slides (key points, data, findings)
- Slide N-1: Key takeaway / summary
- Slide N: Next steps / closing
-
Create the canvas:
a. Start from the
presentationtemplate:python3 scripts/canvas_template.py presentation [output_path] \ --param title="[topic]" --param slide_count=[N]b. Edit each slide's text node with the generated content using the Edit tool.
c. If images requested: generate via
/bananaand add as file nodes inside slide groups.d. If storyboard style: add script annotation text nodes (width=500) to the right of each slide group.
-
Color-code slides per the spec:
- Title/close:
"6"(purple) - Content:
"4"(green) - Key insight:
"5"(cyan) - Action items:
"2"(orange)
- Title/close:
-
Validate:
python3 scripts/canvas_validate.py [output_path] -
Report: "Created [N]-slide presentation at [path]. Open in Obsidian with Advanced Canvas to navigate with arrow keys."
Build from Notes (/canvas present from [notes])
Create a presentation from existing markdown files or wiki pages.
Workflow:
- Find source notes: Search for the specified files. If in a claude-obsidian vault, use
wiki/paths. Otherwise search the current directory.
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-present is a skill published in the GitHub repository AgriciDaniel/claude-canvas (288 stars, last pushed 4mo ago), licensed MIT. It adds 93 tokens to every session and 1,310 once invoked, about $0.0005 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.

autoresearch
Run a bounded, source-grounded research loop, draft a cited dossier, and optionally propose a separately reviewed canonical vault merge. Use when the user wants autonomous or deep research that may access the public web. Triggers: /autoresearch, autoresearch, research this topic, deep dive into, investigate, find…
wiki-ingest
Ingest supplied source material into an Obsidian vault with provenance and claim tracking: pasted text, files staged in the selected vault's inbox or .raw archive, or explicitly approved URLs. Use for a single source or bounded batch, not for saving an assistant answer. Triggers: ingest, ingest this file, ingest this…
canvas
Create, inspect, and update Obsidian JSON Canvas boards with text, file, link, group, and edge nodes. Use for canvas status, canvas lists, visual maps, zones, spatial layouts, adding vault notes or media to a .canvas file, and requests such as create canvas, add to canvas, or put this on the canvas.
defuddle
Plan and, with explicit network consent, use an optional external Defuddle cleaner to extract article-like HTTPS pages as Markdown. Use for defuddle, clean this URL, strip page clutter, readable Markdown from a web page, or preparing a web source for later wiki ingestion.
obsidian-bases
Explain, draft, and validate Obsidian Bases .base files with filters, formulas, properties, summaries, and table, card, or list views. Use for Obsidian Bases, database-like vault views, dynamic tables, reading lists, task trackers, filters, formulas, summaries, and .base file edits.
obsidian-markdown
Explain, draft, or validate Obsidian Flavored Markdown syntax: properties, wikilinks, embeds, callouts, tags, comments, highlights, block references, math, and Mermaid. Use when the user explicitly requests Obsidian note formatting or syntax help, not for general Markdown or broad vault operations.
