This fork of `anthropics/skills` had no automation — staying in sync
required manual git work, and there was no visibility into what changed
or broke when histories diverged.

## What's added

### `.github/workflows/sync-upstream.yml`
Daily cron (06:00 UTC) + `workflow_dispatch` with a `dry_run` toggle.

| Scenario | Action |
|---|---|
| Already in sync | Exit cleanly |
| Upstream-only new commits | Fast-forward merge directly to `main` |
| Diverged histories | Open a labeled PR with full diff context |
| Merge conflicts in diverged PR | Stage conflict markers, list
conflicting files, apply `conflicts` label |

PR body includes a summary table, incoming commit log (up to 50),
changed-files list with status emoji (➕ ✏️ ➖ 🔀), and — when conflicts
exist — a per-file list with step-by-step resolve instructions.
Deduplicates: skips opening a new PR if one is already open.

### `.github/workflows/label-pr.yml` + `.github/labeler.yml`
Auto-labels every PR via `actions/labeler@v5` based on changed paths:
`skills`, `spec`, `template`, `documentation`, `github-actions`.

### `.github/labels.yml`
Label definitions (name, color, description) for all labels used by the
automations, including the new `conflicts` label (red) applied to sync
PRs with unresolved conflicts.

### `.github/CODEOWNERS`
Auto-requests `@d33disc` as reviewer on all PRs.

…rkdownlintignore and pip cache

…kills spec validation (#1)

- [x] Create `pyproject.toml` with ruff and mypy configuration
- [x] Create `.github/workflows/lint-typecheck.yml` — daily auto-fix
workflow (Python + Markdown)
- [x] Create `.markdownlint.json` — MD013.tables: false
- [x] Create `.github/workflows/validate-skills.yml` — Agent Skills spec
validation
- [x] **Fix critical mdformat bug**: `mdformat .` was destroying YAML
frontmatter in all SKILL.md files — now scoped with `find . -name "*.md"
! -name "SKILL.md"` so SKILL.md files are never touched by mdformat
- [x] **Pin all tool versions**: `ruff==0.15.6`, `mypy==1.19.1`,
`mdformat==0.7.22`, `mdformat-tables==1.0.0`, `[email protected]`
— reproducible builds
- [x] **Create `.markdownlintignore`**: excludes
`THIRD_PARTY_NOTICES.md` (auto-generated licence text with 130+
false-positive violations); both auto-fix and report-only markdownlint
steps pass `--ignore-path .markdownlintignore`
- [x] **Add pip caching**: `cache: pip` on setup-python — avoids
re-downloading tools on every daily run
- [x] **Expand validate-skills path trigger**: now also fires when
`scripts/**`, `references/**`, or `assets/**` change — catches broken
file references after a rename/delete

* Fix xlsx SKILL.md frontmatter: add YAML --- markers

The frontmatter was malformed (horizontal rule instead of --- markers,
all fields on one line). This caused the Validate Agent Skills CI to
fail on every push.

* Fix broken YAML frontmatter in 16 skills

All had horizontal rules instead of --- markers and metadata jammed on
a single line, causing Validate Agent Skills CI to fail on every push.

Fixed: algorithmic-art, brand-guidelines, canvas-design, claude-api,
doc-coauthoring, docx, frontend-design, internal-comms, mcp-builder,
pdf, pptx, skill-creator, slack-gif-creator, theme-factory,
web-artifacts-builder, webapp-testing

… add ignore paths, expand triggers

Co-authored-by: d33disc <[email protected]>

…rmat scope, wire up ignore paths (#8)

PR #1 merged with 6 unresolved review comments where the implementation
didn't match the stated intent. This PR fixes all of them.

### `lint-typecheck.yml`

- **Pin tool versions** for reproducible builds: `ruff==0.15.6`,
`mypy==1.19.1`, `mdformat==0.7.22`, `mdformat-tables==1.0.0`,
`[email protected]`
- **Add `cache: pip`** to `setup-python` step
- **Fix mdformat destroying YAML frontmatter** in SKILL.md files —
`mdformat .` replaced with:
  ```bash
  find . -name "*.md" ! -name "SKILL.md" -print0 | xargs -0 mdformat
  ```
- **Wire up `.markdownlintignore`** — add `--ignore-path
.markdownlintignore` to both the auto-fix and report-only markdownlint
steps

### `validate-skills.yml`

- **Expand path triggers** to also fire on `scripts/**`,
`references/**`, `assets/**` changes (catches broken file references
after renames/deletes)

…factor (#9)

- Add `nofonts` package option to tufte-swiss.sty for custom font families
- Fix fontspec "Could not resolve" warnings by declaring all four faces
  (BoldFont/BoldItalicFont) on every \newfontfamily, mapping single-weight
  families to next heavier weight in Aktiv Grotesk
- Add references/FONT_REFERENCE.md: fc-list discovery, four-face rule,
  font pairing principles, optical sizes, LuaLaTeX compilation, troubleshooting
- Refactor SKILL.md: proper YAML frontmatter, 133 lines (was 258+121),
  progressive disclosure with references/ for deep docs
- Delete redundant ORIENTATION.md (merged into SKILL.md)

chore: add .gitignore, symlink ToolUniverse skills from source repo

- Add .gitignore for LaTeX artifacts, Python cache, OS junk
- Ignore ToolUniverse skill dirs (symlinked from ~/code/ToolUniverse/skills/)
- 69 plain-copy dirs replaced with symlinks to single source of truth
- upstream_skills tracks only Anthropic marketplace + 3 custom skills
