Adds a draw.io import path to the skill. Points at a .drawio file and
produces an editorial diagram fitted to where it's going — not a
format conversion.
- scripts/drawio_extract.py: decodes all four containers draw.io writes
(raw XML, deflate+base64 payloads, PNG tEXt chunks, SVG content attrs),
flattens mxGraphModel into absolute-positioned nodes/edges, and reports
structural signals: hubs, containers, depth, cycles, collapsible leaf
groups, budget flags. Deterministic half — makes no design decisions.
- references/output-spec.md: the three dials. Nine size presets with
per-size-class type ramps and safe areas; faithful/balanced/simplified
detail levels with a fixed degrade ladder; engineer/mixed/executive
audience wording; fidelity ledger; CJK font fallback.
- references/import-drawio.md: the redraw procedure — extract, set dials,
pick type, build the semantic model, redraw on the grid. Includes the
draw.io palette/shape → semantic role mappings, multi-page handling,
edge cases, and anti-patterns.
- commands/import-drawio.md: /diagram-design:import slash command.
- SKILL.md: new §11 (import + output dials), taste-gate entries, §12 output.
- export.md: sizing section — scale factors and exact-pixel targets.
- assets/example-import-drawio.html: worked import of the checked-in
fixture at balanced/doc-inline, lint-clean.
- scripts/verify-drawio-import.py: drives the real extractor against the
fixture in all four containers and checks the references stay in sync.
faithful is the one documented exemption from the §7 complexity budget,
and it's conditional: zoned above 9 nodes, split above 24. The §6
connector rules never relax for imported content.

- New type #27: Loop — ring of 5-8 stations around exactly one hub,
solid flow arrows around the ring, dashed write-back spokes into
the hub. Reference doc with ring layout math, budget, and
anti-patterns; flagship example "The self-improving loop" in
light/dark/full variants; gallery tab; README showcase under the
hero image.
- scripts/lint-skin.py — contributor palette linter: reads allowed
tokens from style-guide.md at runtime, flags off-palette hexes,
pure black, external assets, scripts, and off-system fonts.
Baseline file grandfathers pre-2.0 examples; --all --baseline is
green.
- Linter immediately caught 36 near-miss hexes in 9 of the newly
regenerated examples; swapped to exact series-palette tokens and
recaptured the affected screenshots.
Imports the substantive work from the aristide/diagram-design fork (PR #9)
as a curated set:
- 12 new diagram types with reference docs: radar, bar, line, gantt,
scatter, it-state, high-level, process, medallion, data-flow,
dp-integration, dp-security-matrix (26 types total)
- 86-icon monochrome IT/cloud primitive, build script, and gallery
- /diagram-design:export command with PNG/SVG export reference
- Onboarding v2: URL, skill, and folder design-token sources
- Mandatory connector rules (orthogonal elbows, label gaps, fanned
attach points, bridge crossings) + architecture/ER connector upgrades
- Series palette tokens for multi-series chart types
- THIRD_PARTY_LICENSES.md covering Tabler, Simple Icons, log-z, Devicon
Not taken from the fork: plugin-manifest identity changes, the client-brand
takeover of style-guide.md, and client-branded example files. The six
affected type examples were regenerated in the neutral editorial skin with
generic content, and their README screenshots recaptured. Reference docs
for those types were rewritten to semantic tokens and typography roles.
Version: 1.0.0 -> 2.0.0.

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.
