- Add 5 new /ccguide commands to ultimate-guide.md slash commands section
  (init-docs, refresh-docs, diff-docs, search-docs, daily)
- Add .claude/commands/ccguide/ with 5 command files for project-level access
- Document typical daily workflow: init once, then /ccguide:daily every day

+description: Daily update check — official Anthropic docs diff + guide/CC releases digest
+---
+
+Run this sequence in order. Present results as one consolidated report.
+
+## Step 1 — Refresh official docs
+
+Call `refresh_official_docs` MCP tool to fetch the latest Anthropic docs and update the current snapshot.
+
+If it fails (no baseline), tell the user to run /ccguide:init-docs once first, then stop.
+
+## Step 2 — Diff official docs
+
+Call `diff_official_docs` MCP tool to compare baseline vs refreshed current.
+
+## Step 3 — Guide + CC releases digest
+
+Call `get_digest` MCP tool with period: "day"
+
+---
+
+## Output format
+
+Present everything as a single daily briefing:
+
+```
+# Daily Claude Code Update — {today's date}
+
+## Official Anthropic Docs
+{diff results — added/removed/modified sections, or "No changes"}
+
+## Guide + CC CLI
+{digest results — guide CHANGELOG entries + CC releases from last 24h, or "No changes"}
+
+---
+Docs snapshot: {baseline date} → {current date}
+```
+
+Rules:
+- If no changes anywhere: say so clearly in one line, no padding
+- Reproduce ALL URLs verbatim (source URLs, GitHub links)
+- If official docs unchanged AND no guide/CC updates: "Nothing changed in the last 24h."
+- Keep it dense — this is a daily briefing, not a report

+description: Compare official Anthropic docs baseline vs current snapshot (no network — instant)
+---
+
+Use the `diff_official_docs` MCP tool.
+
+No network call — reads local index files only (~50KB each). Instant.
+
+Present the results clearly:
+- Added sections (new pages in the official docs)
+- Removed sections
+- Modified sections with line delta and first changed line
+- Unchanged count
+
+If no baseline exists, tell the user to run /ccguide:init-docs first.
+If no current snapshot exists, tell the user to run /ccguide:refresh-docs first.
+If no changes, confirm everything is in sync and suggest running /ccguide:refresh-docs to update.

+description: Fetch official Anthropic Claude Code docs and store as local baseline snapshot
+---
+
+Use the `init_official_docs` MCP tool.
+
+This fetches ~1.2MB from Anthropic (takes ~5s) and stores 4 local cache files in ~/.cache/claude-code-guide/.
+Both the baseline and current snapshots are set to this version.
+
+After success, tell the user:
+- How many sections were found
+- The snapshot path
+- That they can now run /ccguide:diff-docs after /ccguide:refresh-docs to see what changed

+Use the `refresh_official_docs` MCP tool.

+This fetches ~1.2MB from Anthropic (takes ~5s) and updates only the "current" snapshot.
+The baseline (set by init_official_docs) is never touched.
+
+After success, show the quick diff preview against the baseline that the tool returns.
+Remind the user to run /ccguide:diff-docs for the full detailed diff.

+Default limit: 5 results.
+
+Present each result with:
+- Section title
+- Source URL (reproduce verbatim)
+- Excerpt showing the relevant content

+If no snapshot exists, tell the user to run /ccguide:init-docs first.

 #### Custom agent
 
 A `claude-code-guide` agent is included in `.claude/agents/claude-code-guide.md`. It uses Haiku (fast, cheap) and automatically searches the guide before answering any Claude Code question.
