Generate a self-contained HTML changelog report showing recent documentation

changes with interactive course generation buttons. Use this skill when the

user asks for a docs changelog, documentation report, what changed recently,

recent doc updates as a report, or runs `/docs --report`. Discovers changes

via git history, categorizes them, summarizes what's new, and produces a

stunning Obsidian & Amber themed HTML report where each entry has a

"Create Course" button that copies the course command to clipboard.

# Documentation Changelog Report

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.

## When to Trigger

- User says "docs changelog", "docs report", "what changed in the docs", "recent doc updates report"

- User runs `/docs --report`, `/docs changelog`, or `/docs --report <timeframe>`

- User asks for a visual summary of documentation changes

## The Process (3 Phases)

### Phase 1: Discover Changes

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

```bash

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

```

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

- `/docs --report` → `--since 7d`

- `/docs --report 24h` → `--since 24h`

- `/docs --report 30d` → `--since 30d`

- `/docs --report 2026-03-20` → `--since 2026-03-20`

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

- `added` = new pages

- `changed` = content changed (keyed off `sha256` deltas, so it catches every real update)

- `removed` = pages dropped from the manifest

Each entry already carries `.category`, `.title`, `.url`, `.filename` — no filename-pattern

categorization needed. Map `category` to a label via `manifest-reference.md`.

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

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

### Phase 2: Analyze Changes

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

1. **Read the page** to understand its current content — it's cached at

`~/.claude-code-docs/cache/<filename>`; if missing, fetch it first with

`~/.claude-code-docs/plugin/scripts/fetch-docs.sh get "<filename>"`.

2. v2 commits no prose history, so there is no line-level `git diff` — describe the page's

**current** content and why it matters (it appeared in `added`/`changed` for this window).

3. **Extract key points:** What's new? What was updated? What are the highlights?

4. **Write a 1-2 sentence summary** of the change

5. **Extract 3-6 bullet points** describing specific additions or updates

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

### Phase 3: Generate the HTML Report

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

```bash

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

```

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

**HTML structure:**

```

├── Header (title, date range, sync status badge)

├── Stats bar (count per category with colored numbers)

├── Key Highlights box (3-6 most notable changes)

├── Section per category

│ ├── Section heading (icon, label, count)

│ └── Cards per changed doc

│ ├── Title + tag (New/Updated/Removed)

│ ├── Summary paragraph

│ ├── Bullet list of key changes

│ ├── Source link → official docs URL

│ └── "Create Course" button

└── Footer (generated from, doc count, date)

```

**Design rules (Obsidian & Amber):**

Use these exact CSS variables from the course design system:

```css

:root {

--bg: #0D0D16;

--surface: #161624;

--surface-hover: #1C1A28;

--border: #2A2840;

--text: #E8E0D4;

--text-muted: #5C5852;

--accent: #F0A050;

--accent-dim: rgba(240, 160, 80, 0.08);

--blue: #60A0E0;

--blue-dim: rgba(96, 160, 224, 0.08);

--green: #50C8A0;

--green-dim: rgba(80, 200, 160, 0.08);

--purple: #C080E0;

--purple-dim: rgba(192, 128, 224, 0.08);

--red: #F06060;

--red-dim: rgba(240, 96, 96, 0.06);

--radius: 10px;

}

```

**Typography:** Use the same fonts as the course skill:

```html

<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">

```

- `Instrument Serif` for h1/h2 headings

- `Outfit` for body text

- `JetBrains Mono` for code and badges

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

```css

body::after {

content: '';

position: fixed; top: 0; left: 0;

width: 100%; height: 100%;

pointer-events: none; z-index: 9999; opacity: 0.035;

background-image: url("data:image/svg+xml,..."); /* same noise SVG */

}

```

**Card styling:**

- Background: `--surface` with `--border` border

- Hover: border shifts to `--accent` muted, subtle glow

- Inner shadow highlight: `inset 0 1px 0 rgba(255,255,255,0.04)`

**Tags:**

- `New` → green badge (`--green-dim` bg, `--green` text)

- `Updated` → blue badge (`--blue-dim` bg, `--blue` text)

- `Removed` → red badge (`--red-dim` bg, `--red` text)

- `Beta` → purple badge (`--purple-dim` bg, `--purple` text)

**Category icons:**

- CLI: `>_` (terminal prompt)

- SDK: `{}` (code braces)

- API: `⟡` (diamond)

- Platform: `◈` (nested diamond)

- Prompt Library: `✎` (pen)

- Other: `●` (dot)

### The "Create Course" Button

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

**Button behavior (JavaScript):**

1. On click, copy the command `/docs --course <topic>` to the clipboard

2. Show a toast notification: "Copied! Paste in Claude Code to generate a course."

3. The toast auto-dismisses after 3 seconds

**Button HTML pattern:**

```html

<button class="course-btn" data-topic="hooks" onclick="copyCourseCmd(this)">

<span class="course-btn-icon">▶</span>

Create Course

</button>

```

**Button CSS:**

```css

.course-btn {

display: inline-flex;

align-items: center;

gap: 6px;

padding: 6px 14px;

border-radius: 999px;

border: 1px solid var(--accent);

background: var(--accent-dim);

color: var(--accent);

font-family: 'Outfit', sans-serif;

font-size: 0.78rem;

font-weight: 600;

cursor: pointer;

transition: all 0.2s;

}

.course-btn:hover {

background: var(--accent);

color: var(--bg);

box-shadow: 0 0 20px rgba(240, 160, 80, 0.25);

}

.course-btn-icon {

font-size: 0.65rem;

}

```

**Toast notification:**

```css

.toast {

position: fixed;

bottom: 2rem;

left: 50%;

transform: translateX(-50%) translateY(20px);

background: var(--surface);

border: 1px solid var(--accent);

color: var(--accent);

padding: 0.75rem 1.5rem;

border-radius: var(--radius);

font-family: 'Outfit', sans-serif;

font-size: 0.88rem;

font-weight: 500;

box-shadow: 0 8px 32px rgba(0,0,8,0.5), 0 0 20px rgba(240,160,80,0.15);

opacity: 0;

transition: opacity 0.3s, transform 0.3s;

z-index: 10000;

}

.toast.show {

opacity: 1;

transform: translateX(-50%) translateY(0);

}

```

**JavaScript:**

```javascript

function copyCourseCmd(btn) {

const topic = btn.dataset.topic;

const cmd = '/docs --course ' + topic;

navigator.clipboard.writeText(cmd).then(() => {

showToast('Copied! Paste in Claude Code: ' + cmd);

}).catch(() => {

// Fallback for older browsers

const ta = document.createElement('textarea');

ta.value = cmd; document.body.appendChild(ta);

ta.select(); document.execCommand('copy');

document.body.removeChild(ta);

showToast('Copied! Paste in Claude Code: ' + cmd);

});

}

function showToast(msg) {

let toast = document.getElementById('toast');

if (!toast) {

toast = document.createElement('div');

toast.id = 'toast';

toast.className = 'toast';

document.body.appendChild(toast);

}

toast.textContent = msg;

toast.classList.add('show');

clearTimeout(toast._timeout);

toast._timeout = setTimeout(() => toast.classList.remove('show'), 3000);

}

```

### Phase 4: Open and Present

After generating the HTML:

1. Open it in the browser

2. Tell the user where it's saved: `~/.claude-code-docs/courses/changelog-<date>.html`

3. Summarize the key findings: "Found X changes across Y categories in the last Z days."

4. Mention they can click "Create Course" on any card to copy the course generation command

## URL Generation

Each `manifest-diff.sh` entry already includes the exact `.url` field — use it directly.

(If you need a URL for a filename not in the diff output, look it up:

`jq -r '.pages[] | select(.filename=="<filename>") | .url' ~/.claude-code-docs/paths_manifest.json`.)

## Topic Extraction for Course Buttons

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

- `claude-code__hooks.md` → `hooks`

- `claude-code__hooks-guide.md` → `hooks guide`

- `docs__en__agent-sdk__python.md` → `Agent SDK Python`

- `docs__en__build-with-claude__prompt-caching.md` → `prompt caching`

- `docs__en__agents-and-tools__tool-use__overview.md` → `tool use`

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