svg-diagram

README documents a zero-dependency svg-lint with 12 checks and a lint gate, plus a pinned layout/colour spec, indicating real engineering rigor, though no test suite or CI is shown.

Install uses the standard `npx skills add` flow and a plain curl of a single SKILL.md from the repo; no plaintext secrets or excessive permissions are evident, but the npx/curl download-and-run pattern warrants mild caution.

Solves a common, concrete pain point — agents producing inconsistent or broken diagrams — by pinning layout arithmetic, colour semantics and a linter across architecture, flowchart, sequence, data-flow and lifecycle diagram types.

Last updated 2026-09-03, not archived, 513 stars, and the README reflects a mature multi-agent install matrix, suggesting active upkeep.

README is unusually thorough: install commands per agent surface, explicit file paths, a ten-diagram gallery with rationale, and a table of pinned rules, though the install command field itself is listed as unknown.
