batch-draft-writer

Drafts multiple email replies or follow-ups in batch using the Superhuman Mail MCP server — processing your inbox in bulk rather than one email at a time. Use this skill whenever someone asks to "draft replies to my unread emails", "respond to all my emails", "write follow-ups for my meetings this week", "batch draft responses", "draft emails for all threads that need a reply", "auto-draft my inbox", "help me respond to everything", "write follow-up emails based on my meetings", "process my inbox", "draft responses to these threads", or any variation of wanting multiple emails drafted at once. Also trigger when someone says "I have a bunch of emails to respond to", "help me get through my inbox", "draft a mail merge", "send personalized emails to these people", or wants to create multiple drafts from a single prompt. Trigger broadly — if someone wants more than one email drafted, this skill should activate.

Quality

Content

81%Weight 40%Scale 1-5

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

A clear, highly actionable batch-email-drafting workflow with strong sequencing, explicit approval checkpoints, and a revision loop. Minor room to tighten repeated guidance and convert inline tool-call descriptions into copy-pasteable blocks.

DimensionReasoningScore

Conciseness

Efficient domain-specific guidance with no padding of concepts Claude already knows; the main reducible redundancy is the INBOX-filter rule and voice/tone guidance each being restated across Step 2, Step 4, and the Important guidelines, which keeps it just below 5.

4 / 5

Actionability

Concrete, executable MCP tool calls with named parameters and specific values (e.g. `Superhuman_Mail.list_threads` with `is_unread: true` and `labels: ["INBOX"]`, `create_or_update_draft` with `type`/`thread_id`/`instructions`); falls short of 5 because calls are described in prose rather than as ready-to-paste code blocks and the `instructions` content is described rather than exemplified.

4 / 5

Workflow Clarity

Clear six-step sequence with explicit validation/approval checkpoints (Step 3 present-the-plan gate, Step 5 review-before-send gate) and a revision feedback loop (Step 6), plus an Important-guidelines checklist; the batch-operation cap does not apply because verification steps are present.

5 / 5

Progressive Disclosure

Well-organized with clear section headers and a coherent self-contained workflow needing no external references; nothing requires splitting into separate files, but at ~100 lines with some cross-section repetition it is just shy of the cleanest top-anchor organization.

Description

91%Weight 40%Scale 1-5

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, well-constructed description that clearly states what the skill does and when to use it, with exceptionally thorough natural-language trigger phrases. The only mild weakness is some overlap risk from the explicit 'trigger broadly' guidance.

DimensionReasoningScore

Specificity

States several concrete actions — 'Drafts multiple email replies or follow-ups in batch', 'processing your inbox in bulk' — naming the domain and multiple specific drafting modes; falls short of 5 because the actions are all variants of email drafting rather than a fully comprehensive action set.

4 / 5

Completeness

Explicitly answers both 'what' (drafts multiple email replies/follow-ups in batch via Superhuman Mail MCP) and 'when' (a long list of concrete trigger phrases plus 'Trigger broadly — if someone wants more than one email drafted, this skill should activate').

5 / 5

Trigger Term Quality

Comprehensive coverage of natural user phrases including many synonyms and variations ('draft replies to my unread emails', 'auto-draft my inbox', 'help me get through my inbox', 'draft a mail merge', 'send personalized emails to these people'), matching the top anchor.

5 / 5

Distinctiveness Conflict Risk

Clear niche — batch/multiple email drafting — with distinct triggers, but the 'Trigger broadly — if someone wants more than one email drafted' phrasing introduces minor overlap risk with a general single-reply drafting skill, keeping it just below 5.
