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 | $0.00241 | $0.00241 |
| Opus 5 | $0.00120 | $0.00120 |
| Sonnet 5 | $0.00048 | $0.00048 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
Diagrammer AGENTS.md 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 5d 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.
What it actually says
AGENTS.md — Diagrammer authoring guide
When the user asks for a mind map, concept map, flowchart, tree, dependency
graph, ER diagram, or timeline, produce a single JSON document conforming to
the Diagrammer schema. The full canonical specification — schema, type
selection, visual conventions, ER conventions, anti-patterns, and worked
examples — lives in skills/diagrammer/SKILL.md.
Quick contract
- Top-level keys:
version(always"1"),type,title,nodes,edges. Optionaldescription,meta. type∈mindmap·tree·flowchart·graph·concept·timeline.- ER diagrams →
type: "graph", entities =shape: "rectangle", attributes indescription, edge label carries cardinality ("places (1—N)"). - Output one fenced JSON block. No surrounding prose unless explicitly asked.

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.

Diagrammer AGENTS.md is an instructions file published in the GitHub repository IdraDev/Diagrammer (11 stars, last pushed 4mo ago), licensed MIT. It adds 241 tokens to every session, about $0.0012 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.
