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.

Content

62%

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

The body provides a clear, well-sequenced workflow with strong approval and revision checkpoints, and gives specific MCP tool guidance. Its weaknesses are mild redundancy across sections, prose-described rather than fully templated drafting examples, and a monolithic single-file structure with no external references.

Suggestions

Consolidate the inbox-filtering rule and voice/tone guidance into a single location and cross-reference it, removing the near-duplicate explanations between Step 2/Step 4 and the Important guidelines section.

Add concrete, fill-in-the-ready example `instructions` strings (beyond the one Jake example) so drafts are copy-paste actionable rather than described in prose.

Move the per-tool parameter reference and detailed voice/tone matching notes into a separate reference file and link to it from the body, achieving one-level-deep progressive disclosure.

DimensionReasoningScore

Conciseness

The body is mostly efficient and actionable but repeats guidance — the `labels: ["INBOX"]` rule appears in Step 2 and again nearly verbatim in Important guidelines, and voice/tone matching is explained in both Step 4 and the guidelines — so it could be tightened rather than hitting the lean level-3 anchor.

2 / 3

Actionability

It names concrete MCP tool calls with exact parameters (e.g., `Superhuman_Mail.list_threads` with `is_unread: true` and `labels: ["INBOX"]`, `create_or_update_draft` with `instructions`), but the drafting guidance is prose-described rather than provided as complete copy-paste-ready templates, leaving some key construction detail implicit.

2 / 3

Workflow Clarity

A clear 6-step sequence includes explicit validation checkpoints — the Step 3 approval gate ("Shall I go ahead and draft all of these?"), "Never send without approval," and the Step 6 revision feedback loop — satisfying the batch-operation feedback requirement of the level-3 anchor.

3 / 3

Progressive Disclosure

The skill is well-organized into clear sections but is a single ~109-line file with no bundle files or external references, so content that could be split (e.g., an MCP tool reference or voice-guidance doc) is inline rather than following the one-level-deep reference pattern of level 3.

Description

100%

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

The description is excellent: it states concrete capabilities, includes a rich set of natural trigger phrases, and explicitly covers both what the skill does and when to use it with third-person voice throughout. It is distinguishable from other skills with minimal conflict risk.

DimensionReasoningScore

Specificity

Names concrete actions — "Drafts multiple email replies or follow-ups in batch", "processing your inbox in bulk" — tied to the Superhuman Mail MCP domain, matching the multiple-specific-actions anchor rather than the partial coverage of level 2.

3 / 3

Completeness

Explicitly answers both "what" ("Drafts multiple email replies or follow-ups in batch") and "when" ("Use this skill whenever someone asks to..." with explicit triggers and "Trigger broadly"), satisfying the level-3 anchor.

3 / 3

Trigger Term Quality

Includes many natural phrases users would actually say — "draft replies to my unread emails", "respond to all my emails", "batch draft responses", "auto-draft my inbox", "draft a mail merge" — giving broad coverage of common variations.

3 / 3

Distinctiveness Conflict Risk

Clear niche of batch email drafting via Superhuman Mail MCP with triggers centered on "more than one email drafted at once," making it unlikely to fire for unrelated skills.
