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 | $0.00011 | $0.00296 |
| Opus 5 | $0.00005 | $0.00148 |
| Sonnet 5 | $0.00002 | $0.00059 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade A, and why
create-diagram 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.
What it actually says
create-diagram
Create an architecture or design diagram that explains a selected system view.
Usage
/create-diagram <source-artifact> [<diagram-type>]
Accepted Inputs
- Issue, approved design, ADR, specification, plan, or repository architecture
- Optional diagram type: sequence, class, state machine, ER, or C4
- Desired audience and level of detail
Owning Agent
@plinth-architect
Associated Skill
033-architecture-diagrams
Workflow
- Confirm the diagram purpose, audience, type, and scope.
- Extract only the components and relationships needed for that view.
- Generate the diagram source using the repository convention.
- Check names and relationships against the source artifacts.
- Report the diagram path and any assumptions.
Output
- Diagram source for the selected architecture view
- Concise explanation of scope and assumptions
- Links to the source artifacts represented
Safeguards
- Do not mix unrelated architecture views into one diagram.
- Do not invent components or interactions.
- Do not replace an existing diagram without reviewing its current purpose.
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.

create-diagram is a command published in the GitHub repository jabrena/plinth (435 stars, last pushed today), licensed Apache-2.0. It adds 11 tokens to every session and 296 once invoked, about $0.0001 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.
