name: claude-docs-changelog\ndescription: >\nGenerate a self-contained HTML changelog report showing recent documentation\nchanges with interactive course generation buttons. Use this skill when the\nuser asks for a docs changelog, documentation report, what changed recently,\nrecent doc updates as a report, or runs /docs --report. Discovers changes\nvia git history, categorizes them, summarizes what's new, and produces a\nstunning Obsidian & Amber themed HTML report where each entry has a\n\"Create Course\" button that copies the course command to clipboard.

\n

Documentation Changelog Report

\n

Generate a self-contained HTML report showing recent documentation changes. The report groups changes by category, summarizes what's new or updated, and includes a \"Create Course\" button on each card so the user can instantly generate an interactive course for any topic that caught their eye.

\n

When to Trigger

\n\n

The Process (3 Phases)

\n

Phase 1: Discover Changes

\n

Find what changed, from the manifest's git history:

\n
~/.claude-code-docs/plugin/scripts/manifest-diff.sh --since <timeframe> --json\n
\n

Default timeframe: Last 7 days. The user can specify a different window:

\n\n

Parse the JSON — three arrays, each element a full page entry:

\n\n

Each entry already carries .category, .title, .url, .filename — no filename-pattern\ncategorization needed. Map category to a label via manifest-reference.md.

\n

If all three arrays are empty, tell the user and suggest a wider window.

\n

Limit scope: If there are more than 30 changed pages total, focus on the most recent/notable 30 and note how many were omitted.

\n

Phase 2: Analyze Changes

\n

For each changed page (or the most significant ones if there are many):

\n
    \n
  1. Read the page to understand its current content — it's cached at\n~/.claude-code-docs/cache/<filename>; if missing, fetch it first with\n~/.claude-code-docs/plugin/scripts/fetch-docs.sh get \"<filename>\".
    2. \n
  2. v2 commits no prose history, so there is no line-level git diff — describe the page's\ncurrent content and why it matters (it appeared in added/changed for this window).
    3. \n
  3. Extract key points: What's new? What was updated? What are the highlights?
    4. \n
  4. Write a 1-2 sentence summary of the change
    5. \n
  5. Extract 3-6 bullet points describing specific additions or updates
    6. \n
\n

For added entries: Read the full page and summarize what it covers.\nFor changed entries: The sha256 delta says the content changed but not where — read the current page and highlight the sections most likely to be new or updated.\nFor removed entries: The page is gone from the manifest (no content to read) — note what was removed with a one-line description built from its title and category.

\n

Group related changes (e.g., if 6 SDK language docs were all updated the same way, combine them into one card).

\n

Phase 3: Generate the HTML Report

\n

Generate a single self-contained HTML file using the Obsidian & Amber design system. Save to:

\n
mkdir -p ~/.claude-code-docs/courses\n
\n

Name the file: ~/.claude-code-docs/courses/changelog-<date>.html (e.g., changelog-2026-03-28.html)

\n

HTML structure:

\n
├── Header (title, date range, sync status badge)\n├── Stats bar (count per category with colored numbers)\n├── Key Highlights box (3-6 most notable changes)\n├── Section per category\n│   ├── Section heading (icon, label, count)\n│   └── Cards per changed doc\n│       ├── Title + tag (New/Updated/Removed)\n│       ├── Summary paragraph\n│       ├── Bullet list of key changes\n│       ├── Source link → official docs URL\n│       └── \"Create Course\" button\n└── Footer (generated from, doc count, date)\n
\n

Design rules (Obsidian & Amber):

\n

Use these exact CSS variables from the course design system:

\n
:root {\n  --bg: #0D0D16;\n  --surface: #161624;\n  --surface-hover: #1C1A28;\n  --border: #2A2840;\n  --text: #E8E0D4;\n  --text-muted: #5C5852;\n  --accent: #F0A050;\n  --accent-dim: rgba(240, 160, 80, 0.08);\n  --blue: #60A0E0;\n  --blue-dim: rgba(96, 160, 224, 0.08);\n  --green: #50C8A0;\n  --green-dim: rgba(80, 200, 160, 0.08);\n  --purple: #C080E0;\n  --purple-dim: rgba(192, 128, 224, 0.08);\n  --red: #F06060;\n  --red-dim: rgba(240, 96, 96, 0.06);\n  --radius: 10px;\n}\n
\n

Typography: Use the same fonts as the course skill:

\n
<link href=\"https://fonts.googleapis.com/css2?family=Instrument+Serif:ital@0;1&family=Outfit:wght@300;400;500;600;700&family=JetBrains+Mono:wght@400;500&display=swap\" rel=\"stylesheet\">\n
\n\n

Include the grain overlay (same as course design system):

\n
body::after {\n  content: '';\n  position: fixed; top: 0; left: 0;\n  width: 100%; height: 100%;\n  pointer-events: none; z-index: 9999; opacity: 0.035;\n  background-image: url(\"data:image/svg+xml,...\");  /* same noise SVG */\n}\n
\n

The \"Create Course\" Button

\n

Each card gets a button in its footer area that lets the user generate a course for that topic.

\n

Button behavior (JavaScript):

\n
    \n
  1. On click, copy the command /docs --course <topic> to the clipboard
    2. \n
  2. Show a toast notification: \"Copied! Paste in Claude Code to generate a course.\"
    3. \n
  3. The toast auto-dismisses after 3 seconds
    4. \n
\n

Button HTML pattern:

\n
<button class=\"course-btn\" data-topic=\"hooks\" onclick=\"copyCourseCmd(this)\">\n  <span class=\"course-btn-icon\">▶</span>\n  Create Course\n</button>\n
\n

Button CSS:

\n
.course-btn {\n  display: inline-flex;\n  align-items: center;\n  gap: 6px;\n  padding: 6px 14px;\n  border-radius: 999px;\n  border: 1px solid var(--accent);\n  background: var(--accent-dim);\n  color: var(--accent);\n  font-family: 'Outfit', sans-serif;\n  font-size: 0.78rem;\n  font-weight: 600;\n  cursor: pointer;\n  transition: all 0.2s;\n}\n.course-btn:hover {\n  background: var(--accent);\n  color: var(--bg);\n  box-shadow: 0 0 20px rgba(240, 160, 80, 0.25);\n}\n.course-btn-icon {\n  font-size: 0.65rem;\n}\n
\n

Toast notification:

\n
.toast {\n  position: fixed;\n  bottom: 2rem;\n  left: 50%;\n  transform: translateX(-50%) translateY(20px);\n  background: var(--surface);\n  border: 1px solid var(--accent);\n  color: var(--accent);\n  padding: 0.75rem 1.5rem;\n  border-radius: var(--radius);\n  font-family: 'Outfit', sans-serif;\n  font-size: 0.88rem;\n  font-weight: 500;\n  box-shadow: 0 8px 32px rgba(0,0,8,0.5), 0 0 20px rgba(240,160,80,0.15);\n  opacity: 0;\n  transition: opacity 0.3s, transform 0.3s;\n  z-index: 10000;\n}\n.toast.show {\n  opacity: 1;\n  transform: translateX(-50%) translateY(0);\n}\n
\n

JavaScript:

\n
function copyCourseCmd(btn) {\n  const topic = btn.dataset.topic;\n  const cmd = '/docs --course ' + topic;\n  navigator.clipboard.writeText(cmd).then(() => {\n    showToast('Copied! Paste in Claude Code: ' + cmd);\n  }).catch(() => {\n    // Fallback for older browsers\n    const ta = document.createElement('textarea');\n    ta.value = cmd; document.body.appendChild(ta);\n    ta.select(); document.execCommand('copy');\n    document.body.removeChild(ta);\n    showToast('Copied! Paste in Claude Code: ' + cmd);\n  });\n}\n\nfunction showToast(msg) {\n  let toast = document.getElementById('toast');\n  if (!toast) {\n    toast = document.createElement('div');\n    toast.id = 'toast';\n    toast.className = 'toast';\n    document.body.appendChild(toast);\n  }\n  toast.textContent = msg;\n  toast.classList.add('show');\n  clearTimeout(toast._timeout);\n  toast._timeout = setTimeout(() => toast.classList.remove('show'), 3000);\n}\n
\n

Phase 4: Open and Present

\n

After generating the HTML:

\n
    \n
  1. Open it in the browser
    2. \n
  2. Tell the user where it's saved: ~/.claude-code-docs/courses/changelog-<date>.html
    3. \n
  3. Summarize the key findings: \"Found X changes across Y categories in the last Z days.\"
    4. \n
  4. Mention they can click \"Create Course\" on any card to copy the course generation command
    5. \n
\n

URL Generation

\n

Each manifest-diff.sh entry already includes the exact .url field — use it directly.\n(If you need a URL for a filename not in the diff output, look it up:\njq -r '.pages[] | select(.filename==\"<filename>\") | .url' ~/.claude-code-docs/paths_manifest.json.)

\n

Topic Extraction for Course Buttons

\n

The data-topic attribute on each course button should be the human-readable topic name extracted from the filename:

\n\n

Strip the category prefix, replace __ and - with spaces, and capitalize naturally.
