Move SKILL.md, references/, and assets/ into skills/diagram-design/
and drop `"skills": ["./"]` from .claude-plugin/plugin.json.
Current state fails to load in Claude Code with:
skills path escapes plugin directory: ./
→ Paths in plugin.json must not use ".." to reference files outside the plugin directory
Claude Code's plugin loader rejects `"./"` as a skill path because
it's ambiguous (plugin root vs. parent) and fails closed to prevent
path-escape attacks. The conventional layout is `skills/<name>/SKILL.md`
per plugin (compare obsidian-skills, claude-plugins-official).
README.md links are updated to point at the new paths so they keep
resolving on GitHub. SKILL.md's internal relative links (e.g.
`references/style-guide.md`) are unchanged — they still resolve
correctly from its new location.
Tested locally: plugin reloads cleanly with no errors and the skill
appears in /skills.
Adds .claude-plugin/plugin.json and .claude-plugin/marketplace.json so the repo can be installed via /plugin marketplace add. Uses "skills": ["./"] so the existing root SKILL.md is picked up without relocation — standalone install path is unchanged. Also removes stray Cocoon AI author reference from SKILL.md frontmatter.
Thirteen editorial diagram types (architecture, flowchart, sequence,
state, ER, timeline, swimlane, quadrant, nested, tree, layers, venn,
pyramid) as self-contained HTML files with inline SVG.
Progressive disclosure: lean SKILL.md points to per-type references.
