An inbox-checking workflow for Microsoft Outlook that reads messages and can add a summary to an Obsidian daily note. Outlook is Microsoft's email service, and Obsidian is a note-taking application.

Use it to check unread, flagged, all, or directly addressed messages, and optionally update the day's note with a summary.

It removes the need to manually scan unread, flagged, or directly addressed messages and copy their details into your notes.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00014	$0.01235
Opus 5	$0.00007	$0.00617
Sonnet 5	$0.00003	$0.00247
Haiku 4.5	$0.00001	$0.00123

Security

Grade A, and why

check-inbox scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Skill: Check Inbox

Command: /check-inbox Model: Haiku (coordinator) / any (note creation) Agent: main

Description

Check Outlook inbox for unread messages using Playwright. Extracts sender, subject, time, and flags from the DOM, then optionally updates the daily note with an inbox summary.

Prerequisites

Playwright installed (@playwright/test in devDependencies)
Microsoft Edge installed
Authenticated session (run npm run inbox:check without --headless once to authenticate)

Usage

/check-inbox                    # Check unread messages (default)
/check-inbox flagged            # Check flagged messages
/check-inbox all                # Check all messages (no filter)
/check-inbox to-me              # Messages addressed directly to me
/check-inbox --no-daily         # Don't update daily note

Workflow

Step 1: Capture inbox data

Run the inbox check script:

node .claude/scripts/outlook-inbox.js --headless

For other filters:

node .claude/scripts/outlook-inbox.js --headless --filter flagged
node .claude/scripts/outlook-inbox.js --headless --filter all
node .claude/scripts/outlook-inbox.js --headless --filter to-me

This outputs:

JSON message data at .claude/logs/inbox-messages-{filter}-{timestamp}.json
Screenshot at .claude/logs/inbox-screenshot-{filter}-{timestamp}.png

If the script fails with "Session expired", re-run without --headless:

node .claude/scripts/outlook-inbox.js

Step 2: Read and present results

Find the most recent inbox JSON file:

.claude/logs/inbox-messages-unread-*.json

Read the JSON and screenshot
Present to the user as a summary table:

Inbox — 3 unread messages (10:56 AM)

| Sender               | Subject                       | Time     | Flags   |
|----------------------|-------------------------------|----------|---------|
| Alex Johnson  | Accepted: What is AlertHub   | 10:05 AM | MEETING |
| Chris Taylor      | Re: Pen re-test               | 9:57 AM  |         |
| Udemy Business       | New courses are waiting...    | 10:30 AM |         |

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
