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 5.1 | $0.00030 | $0.02759 |
| Opus 5.5 | $0.00012 | $0.01104 |
| Sonnet 5.5 | $0.00006 | $0.00552 |
| Haiku 4.5 | $0.00003 | $0.00276 |
Grade C, and why
draw scanned grade C with 2 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 2mo 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
If a `yuzudraw-cli` command fails with "command not found", ask the user to install it with `curl -fsSL https://www.yuzudraw.com/install.sh | sh`, then retry. How it starts
The opening of the file, as written. The whole thing — 300 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/draw — Create Diagrams in YuzuDraw
Use this as the single entrypoint for diagram work. Select one family, open the matching reference, then write DSL.
Workflow
- Classify the request into one primary diagram family.
- Open the matching reference file under
references/. - Follow that reference's defaults instead of improvising a generic style.
- Pass DSL to CLI commands using a heredoc with
--dsl-stdin(see CLI Invocation Rules below). Every command MUST start withyuzudraw-cli— never use pipes,cat, orecho. - Always display the rendered ASCII output in a fenced code block in your response so the user can see it directly without expanding tool results.
- After rendering, ask the user if they'd like to save the diagram (via
create-diagramorupdate-diagram). Always prompt — don't assume they only wanted a preview.
If a yuzudraw-cli command fails with "command not found", ask the user to install it with curl -fsSL https://www.yuzudraw.com/install.sh | sh, then retry.
CLI Invocation Rules
Every CLI call MUST start with yuzudraw-cli so it can be allowlisted. Pass DSL inline via heredoc — no temp files, no pipes, no cat/echo.
- Render:
yuzudraw-cli render-ascii --dsl-stdin <<'EOF' rect "hello" id box at 5,5 size 10x3 EOF - Create:
yuzudraw-cli create-diagram --name <name> --dsl-stdin <<'EOF' ...DSL... EOF - Update:
yuzudraw-cli update-diagram --name <name> --dsl-stdin <<'EOF' ...DSL... EOF
Do NOT use pipes (cat file | yuzudraw-cli), --dsl-file, or any command that does not start with yuzudraw-cli.
Family Selection
Open architecture.md when the request is about:
- system topology
- regions, zones, groups, tiers
- cross-boundary relationships
- repeated nodes and framed areas
- high-level runtime structure
Open components.md when the request is about:
- modules, packages, services, subsystems
- interfaces, APIs, dependencies
- internal product structure
- ownership or containment boundaries
What ships with it
6 files 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.

draw is a skill published in the GitHub repository agavra/yuzudraw (55 stars, last pushed 7mo ago), licensed MIT. It adds 30 tokens to every session and 2,759 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
