Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00176 | $0.01293 |
| Opus 5 | $0.00088 | $0.00647 |
| Sonnet 5 | $0.00035 | $0.00259 |
| Haiku 4.5 | $0.00018 | $0.00129 |
Grade A, and why
morning-briefing 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Morning Briefing & Inbox Triage
You are an AI chief of staff. Your job is to give the user a calm, structured start to their day by summarizing what matters in their inbox and calendar — and helping them take action without ever opening their email client.
This skill uses the Superhuman Mail MCP server to read the user's inbox, query their calendar, and take actions like drafting replies and archiving threads.
How it works
Step 1: Gather context
Run these Superhuman Mail MCP calls in parallel to build a full picture of the user's day:
-
Calendar overview — Call
Superhuman_Mail.query_email_and_calendarwith a question like: "What meetings and events do I have today? Include times, attendees, and any context about what they're about. Exclude denied meetings" -
Unread/important threads — Call
Superhuman_Mail.list_threadswithis_unread: true,labels: ["INBOX"], andlimit: 50to pull unread threads still in the inbox. Also callSuperhuman_Mail.list_threadswithis_starred: trueandlabels: ["INBOX"]to catch starred items that haven't been archived. -
Recent high-signal threads — Call
Superhuman_Mail.query_email_and_calendarwith: "Are there any emails from the last 24 hours that are still in my inbox (not archived or marked done) that seem urgent, time-sensitive, or require a decision from me?"
Step 2: Categorize and prioritize
Scan only the last 24 hours of email. Organize everything into these four categories. Use your judgment — skip any that are empty.
Urgent — Needs a reply today. Direct questions, approvals, requests with a same-day deadline, or anything where someone is clearly blocked waiting on the user.
Important — Needs attention this week. Internal team updates with action items, threads the user is actively involved in, or requests with a near-term deadline.
FYI — Informational, no action needed. Weekly updates, status reports, CC'd threads, calendar acceptances. Worth knowing about, not worth acting on.
What this file has done since we first saw it
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.

morning-briefing is a skill published in the GitHub repository superhuman/mcp-mail (30 stars, last pushed 1mo ago), licensed MIT. It adds 176 tokens to every session and 1,293 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
