aid-create-diagram

aid-create-diagram is a skill for Claude Code from AndreVianna/aid-methodology. It costs 155 tokens per session (418 once invoked), scanned A, original, MIT.

A diagram-creation skill that chooses a suitable diagram style and produces it in Mermaid or Graphviz. It can represent flows, message sequences, database relationships, system structure, or states.

In plain words
What is it for?
Use it to create flowcharts, sequence diagrams, entity-relationship diagrams, C4 system diagrams, state diagrams, and similar visuals. The result is a diagram, not an implementation.
Why use it?
It helps explain a subject visually when prose would take longer. You do not need to choose the diagram notation yourself.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

aid-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 25d 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

Create Diagram (kind-sibling of /aid-create-document)

/aid-create-diagram is a thin kind-sibling of /aid-create-document (.agents/skills/aid-create-document/SKILL.md) -- not an alias: it is its own catalog row (alias_of: null, its own {verb: create, artifact: diagram}), repurpose: true (skipped by build-shortcut-skills.py; hand-authored). It carries no logic of its own.

Execute .agents/skills/aid-create-document/SKILL.md exactly as written, with the output format bound to diagram (mermaid/graphviz; pick the diagram type -- flowchart, sequence, ER, C4, state, ... -- that fits the subject). Substitute only the invocation name in any printed usage example (/aid-create-diagram instead of /aid-create-document). Deeper genre/format structures: .aid/runtime/templates/shortcut-scaffolding/document.md.

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.
