Daily Digest

Automated daily summary of your recent thoughts, delivered to your inbox.

What It Does

Queries your most recent Open Brain thoughts, groups them by type and topic, and delivers a formatted summary. You wake up to a digest of everything your brain captured yesterday.

There are two approaches — pick the one that fits your setup:

Approach	Infrastructure	Difficulty	Auto-send?
Claude Code Scheduled Task (below)	None — uses MCP tools you already have	Beginner	Draft only (one-tap send)
Supabase Edge Function (planned)	Edge Function + pg_cron + email service	Intermediate	Full auto-send

---

Approach A: Claude Code Scheduled Task

Zero-infrastructure variant. If you already run Claude Code (or Claude Desktop's Code mode) with Open Brain MCP and Gmail MCP connected, this works today with no deployment.

Prerequisites

• Working Open Brain setup (guide)
• Claude Code or Claude Desktop (Code mode) with:
  • Open Brain MCP connected
  • Gmail MCP connected (for email delivery)

How It Works

Claude Code has built-in scheduled tasks (visible in Claude Desktop under the Scheduled tab). You install a skill file — a prompt template — that tells Claude what to do on each run:

1. Query Open Brain for thoughts from the last 24 hours
2. Organize them into a scannable digest (grouped by type, with topic/people tags)
3. Create a Gmail draft addressed to you

Claude is the LLM — no OpenRouter key needed.

Steps

Copy the skill template into your Claude scheduled tasks directory:

mkdir -p ~/.claude/scheduled-tasks/daily-digest
cp recipes/daily-digest/daily-digest-skill.md ~/.claude/scheduled-tasks/daily-digest/SKILL.md

Then open the file and replace YOUR_EMAIL@example.com with your actual email address.

Important

The skill file is a local prompt — it never gets committed to any repo. Your email stays on your machine.

---

In any Claude Code session (or Claude Desktop Code mode), run:

/schedule

Or create it directly by telling Claude:

"Create a scheduled task called daily-digest that runs every day at 7am using the skill file at ~/.claude/scheduled-tasks/daily-digest/SKILL.md"

The task will appear in Claude Desktop's Scheduled tab.

---

Click "Run now" from the Scheduled tab to do an initial test. On the first run, Claude will ask for permission to use the Open Brain and Gmail MCP tools. Approve them once — future runs will remember.

Tip

If you haven't captured any thoughts recently, the digest will say so. Capture a few test thoughts first via capture_thought to see the full format.

---

Expected Outcome

Every morning, a Gmail draft appears in your inbox with:

• A count of thoughts captured in the last 24 hours
• Breakdown by type (observations, tasks, ideas, references, person notes)
• Each thought's content (truncated), source, and topic/people tags
• A summary header with top themes

You review the draft and hit send (or just read it).

Troubleshooting

Issue: Scheduled task never fires Solution: Claude Code must be running (or Claude Desktop must be open) at the scheduled time. If your machine was asleep, the task fires on next launch.

Issue: Task pauses waiting for permissions Solution: Run it manually once via the Scheduled tab and approve the MCP tool permissions. They persist for future runs.

Issue: "No thoughts found" every day Solution: Check that your Open Brain MCP is connected and has recent data. Run list_thoughts manually in a Claude Code session to verify.

Issue: Gmail draft not appearing Solution: Verify your Gmail MCP connector is working. Try gmail_create_draft manually in a Claude session to test.

Approach B: Supabase Edge Function (Planned)

A fully self-contained approach using a Supabase Edge Function, pg_cron trigger, and an email service (Resend or SendGrid) for true automated delivery without Claude running. This approach is not yet implemented — contributions welcome.

Prerequisites (planned)

• Supabase CLI available (Homebrew/Scoop/standalone binary or npx supabase; npm i -g supabase is not supported)
• OpenRouter API key (for generating the summary)
• Email service: Resend or SendGrid (free tier)
