plantuml
Generate PlantUML diagrams from text descriptions and convert them to PNG/SVG images. Use when asked to "create a diagram", "generate PlantUML", "convert puml to image", "extract diagrams from markdown", or "prepare markdown for Confluence". Supports all PlantUML diagram types including UML (sequence, class, activity, state, component, deployment, use case, object, timing) and non-UML (ER diagrams, Gantt charts, JSON/YAML visualization, mindmaps, WBS, network diagrams, wireframes, and more).

Developer Feedback
I took a look at your plantuml skill and wanted to share some thoughts.

The TL;DR
You're at 88/100, solid B grade territory. This is based on Anthropic's skill best practices rubric. Your strongest area is Ease of Use (23/25) — the trigger phrases and metadata are really well thought out. The weakest spot is Spec Compliance (13/15), which is mostly a formality issue, not a functionality problem.
What's Working Well
Five crystal-clear trigger phrases in your metadata ("create diagram", "generate PlantUML", "convert puml", "extract diagrams", "prepare markdown for Confluence") — this is chef's kiss for discoverability. Most skills are vague here; yours tells users exactly when to call it.
Progressive disclosure architecture is solid. SKILL.md stays lean as an index, and you've got 39 reference files organized logically under
references/,troubleshooting/, andworkflows/. Users can dive deep without drowning in the overview.Practical utility across three major workflows: text-to-diagram, code-to-diagram, and markdown processing. You're solving real problems developers actually face, especially the Confluence conversion angle.
The Big One: Redundant References Section
Your SKILL.md has a References section (lines 284-309) that duplicates navigation you already provided earlier. You list the same 19 diagram types both in your intent-to-diagram table AND again in the References section. This costs you about 2 points in Progressive Disclosure (Token Economy pillar).
The fix: Delete the redundant References section entirely. Your earlier "Get Started" section with the intent-to-diagram table already does the heavy lifting. If you want a references footer, make it a single compact link to `...
