diagram-forge

diagram-forge is a plugin for Claude Code from jessepike/diagram-forge. Its manifest loads nothing; the 1 skill, 4 commands, 1 agent it bundles cost 159 tokens per session together, scanned A, original, MIT.

A plugin for generating architecture diagrams from natural-language descriptions using Gemini or OpenAI. It requires an API key for the image-generation provider you choose.

In plain words
What is it for?
Use it to create architecture diagrams with Gemini or OpenAI after configuring the relevant API key.
Why use it?
It reduces the work of turning a written system description into an architecture diagram.

Security

Grade A, and why

diagram-forge 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 3d 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 installs

The manifest is a name and a version. 1 skill, 4 commands, 1 agent travel with it, and installing the plugin installs all of them — 159 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

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.
