tikz-diagrams SKILL.md skillA

tikz-diagrams from vecnode/vncode is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add vecnode/vncode/tikz-diagrams@git:20260920.25904b4

Pins git:20260920.25904b4 in mdr.lock. Pin the fingerprint instead.

Author TikZ/LaTeX diagrams that compile: use the host's prepared preamble, the right libraries, layout and plot recipes, and read the compiler's line-accurate errors to converge in a couple of writes. A bundled reference covers complex, large pictures.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# TikZ diagrams

You are writing LaTeX/TikZ for the **`diagram_write`** tool of this harness. The
host compiles every write with the machine's own TeX engine and returns the
compiler's diagnostics, so the loop is:

```
diagram_write { kind: "tikz", title: "Layered architecture", source: "..." }
  -> status "ok"          : compiled; the PDF/SVG is cached and rendering
  -> status "error"       : fix `diagram.tex:LINE: ...` and write again
  -> status "unavailable" : no TeX engine on this host (or the diagram was
                            stored but not compiled) - say so, and offer the .tex
```

Rules that matter:

- **Never finish on a non-`ok` status.** If TeX is unavailable, tell the user
  plainly and hand over the source, which still exports as `.tex`.
- TikZ pays off for **precision** (alignment, arrows, annotations, plots) and
  loses to Mermaid for rough, quickly-changing pictures. Choose accordingly.
- A diagram that fits one page at a readable size is the target. Prefer
  **≤ 40 nodes** and **≤ 200 lines**; split anything larger.
- Iterate with **`diagram_patch`** (literal replace) - never re-emit a long
…

How to install

The exact contents, by fingerprint
mdr add vecnode/vncode/tikz-diagrams@sha256:b12867342fe02448

The line at the top of this page pins the label git:20260920.25904b4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
