morning-briefing

Generates a morning briefing that triages your inbox and previews your day using the Superhuman Mail MCP server — acting as an AI chief of staff. Use this skill whenever someone asks to "brief me on my day", "triage my inbox", "what's important in my email", "summarize my unread emails", "what do I need to deal with today", "chief of staff briefing", "morning update", "inbox summary", "what emails need my attention", "clear my inbox", or any variation of wanting a prioritized view of their email and calendar before they start working. Also trigger when someone says "I just woke up, what's going on" or "catch me up on my inbox". Trigger broadly — if someone wants to understand the state of their inbox or day at a glance, this skill should activate.

Quality

Content

100%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-crafted, actionable skill body that gives specific MCP calls with parameters, a clear four-step workflow, and explicit guardrails gating destructive actions behind user approval. It is concise without padding and appropriately organized for a self-contained single-purpose skill.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence — it never explains concepts Claude already knows and every section (parallel MCP calls, category definitions, output template, guardrails) earns its place.

3 / 3

Actionability

Provides concrete, executable guidance with exact tool calls and parameters (e.g., `Superhuman_Mail.list_threads` with `is_unread: true`, `labels: ["INBOX"]`, `limit: 50`; `update_thread` with `mark_done: true`), plus a copy-ready briefing template and specific action offerings.

3 / 3

Workflow Clarity

A clearly sequenced four-step workflow (gather context in parallel → categorize → present → offer actions) with the destructive/batch archive operation gated behind explicit user approval ("Never send an email without explicit user approval"), plus conditional-handling rules for edge cases like a very full inbox.

3 / 3

Progressive Disclosure

A self-contained, single-purpose skill with no need for external references, organized into clear headed sections (How it works, four numbered steps, Important notes) — well-organized and easy to navigate without file splitting.

Description

100%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, complete description that pairs concrete capabilities with an explicit, broad set of natural-language triggers and a clear what/when structure. It is somewhat verbose for a description, but the length comes from trigger coverage and explicit guidance rather than fluff.

DimensionReasoningScore

Specificity

Names multiple concrete actions — "triages your inbox", "previews your day", "Generates a morning briefing" — and the specific tool (Superhuman Mail MCP server), matching the anchor for listing several specific concrete actions.

3 / 3

Completeness

Clearly answers both what it does (triage inbox, preview day, generate briefing) and when to use it via an explicit "Use this skill whenever someone asks to..." trigger clause, satisfying the anchor for answering both what AND when.

3 / 3

Trigger Term Quality

Includes extensive natural phrases a user would actually say ("brief me on my day", "triage my inbox", "what's important in my email", "summarize my unread emails", "clear my inbox", "I just woke up, what's going on"), giving strong coverage of common variations.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche — a morning briefing / inbox triage via the Superhuman Mail MCP server — with triggers specific to that use case, making it unlikely to fire for unrelated skills.
