What it does

Drawing Diagrams is an agent skill from dxos/dxos. Draw an architecture diagram of DXOS code (a package, a module graph, a subsystem) by writing plugin-illustrator's semantic diagram DSL (.dx), rendering it, and looking at the image before showing it. Use when asked to draw, render, or show a diagram of the codebase, to "use the illustrator" on something, to add or regenerate a diagram in packages/plugins/plugin-illustrator/docs/diagrams/, or to judge the layout engine on a real graph. For a hand-drawn explanatory figure inside an Artifact page, use…

Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Diagrams. It works with Adobe Illustrator. The repository describes itself as: TypeScript implementation of the DXOS protocols, SDK, toolchain and Composer.

When your agent uses it

  • Show a diagram of the codebase
  • Use the illustrator on something
  • Regenerate a diagram in packages/plugins/plugin-illustrator/docs/diagrams/
  • Judge the layout engine on a real graph

Example prompts

  • “use the illustrator”
  • “/drawing-diagrams”

Requirements

  • A credential in CLOUDFLARE_API_TOKEN

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Derive the graph from the code, not from memory
  2. Write the DSL
  3. Render
  4. Look at it before you submit it
  5. Show it

What it can do on your machine

Read from SKILL.md and the folder at commit 085dcb1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • node
    • bash
    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • CLOUDFLARE_API_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Drawing Diagrams loads about 2.6k tokens when it runs. Until then it costs about 139 tokens; SKILL.md has 1,351 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~139
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,351 words (~2,634 tokens).

“Write the diagram in the semantic DSL: say what is related and, only where it matters, roughly where. The engine (SemanticEngine in @dxos/diagram) puts the boxes on a grid, routes arrows through the gutters with the fewest bends, spreads the…”
