Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 5.1 | $0.00088 | $0.00992 |
| Opus 5 | $0.00044 | $0.00496 |
| Sonnet 5 | $0.00018 | $0.00198 |
| Haiku 4.5 | $0.00009 | $0.00099 |
Grade A, and why
canvas-template 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.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
canvas-template: Template Browser & Instantiation
Operations
List Templates (/canvas template list)
Run the template script to list available archetypes:
python3 scripts/canvas_template.py --list
Present the results as a formatted table:
| Archetype | Layout | Description |
|---|---|---|
| presentation | linear-vertical | Slide deck for Advanced Canvas (1200x675 slides) |
| flowchart | linear-vertical → auto dagre | Process flow with connected step nodes |
| mind-map | grid → auto radial | Radial expansion from central topic |
| gallery | grid | Image placeholder grid with title zone |
| dashboard | grid | Metric cards + status zones |
| storyboard | linear-horizontal | Scene cards for video planning |
| knowledge-graph | grid → auto force | Entity nodes for relationship mapping |
| mood-board | grid | Asymmetric image grid for creative direction |
| timeline | linear-horizontal | Horizontal event sequence |
| comparison | grid | Side-by-side columns for option analysis |
| kanban | grid | Todo/Doing/Done column board |
| project-brief | linear-vertical | Stacked zones for project kickoff |
Instantiate Template (/canvas template use [name])
- Validate the template name against the 12 archetypes.
- Ask for required parameters:
- title (all templates): What's the canvas title?
- Template-specific params (slide_count, step_count, image_count, etc.)
- Determine output path (canvas directory detection from orchestrator).
- Run instantiation:
python3 scripts/canvas_template.py [template] [output_path] --param title="[title]" --param [key]=[value]
- Validate the output:
python3 scripts/canvas_validate.py [output_path]
- MANDATORY: Content Quality Gate — Read the orchestrator's Quality Standards section. Before reporting:
- Replace ALL placeholder text in every node with real content relevant to the title
- Verify no "Describe this", "YYYY-MM-DD", "Value: 0", or "Content goes here" strings remain
- Run
python3 scripts/canvas_validate.pyand confirm 0 errors, 0 overlap warnings - If the template has
post_layout(mind-map→radial, knowledge-graph→force, flowchart→dagre), confirm the layout was applied
- Report: "Created [name] canvas at [path] with [N] nodes, [E] edges, [G] groups."
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-template is a skill published in the GitHub repository AgriciDaniel/claude-canvas (292 stars, last pushed 5mo ago), licensed MIT. It adds 88 tokens to every session and 992 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.
