Quality

Content

85%

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

The body is highly actionable with executable commands, clear send/confirm workflows, and clean one-level-deep references to bundled scripts; its main weakness is redundancy in credential-handling guidance spread across multiple sections.

Suggestions

Consolidate the repeated credential/app-password/authorization-code guidance into a single 'Credentials' section instead of restating it in Configuration Reference, Security Notes, and Troubleshooting.

Move the full `.env` variable reference and provider port table into a dedicated reference file (e.g. references/CONFIG.md) and link to it from the body to tighten the SKILL.md overview.

DimensionReasoningScore

Conciseness

The body avoids explaining concepts Claude already knows and uses efficient command tables, but the credential-handling caveats are restated across the front-matter, Configuration Reference, Security Notes, and Troubleshooting sections, so it could be tightened rather than earning the lean score-3 anchor.

2 / 3

Actionability

Provides fully executable `node scripts/...` commands with complete flag lists and concrete copy-paste-ready send examples, matching the score-3 anchor rather than incomplete pseudocode.

3 / 3

Workflow Clarity

The send flow has an explicit confirmation checkpoint ('review recipient, subject, sender account, and body first... blocked unless --confirmed'), plus error-recovery guidance for command failures and SMTP result interpretation, matching the score-3 anchor with checkpoints and feedback loops.

3 / 3

Progressive Disclosure

Real bundle scripts (scripts/imap.js, smtp.js, config.js) are referenced one level deep via clear `node scripts/...` navigation, and the body is organized into well-signaled sections; the inline config/server tables are appropriate for this skill's scope.

Description

82%

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 specific and distinct, listing concrete email actions and natural trigger terms, but it omits an explicit 'Use when...' trigger clause, which caps completeness at 2.

Suggestions

Add an explicit 'Use when...' clause, e.g. 'Use when the user wants to read, search, or send email via IMAP/SMTP' to answer the 'when to use it' question.

Consider trimming the long provider enumeration ('163.com, vip.163.com, 126.com, vip.126.com, 188.com, vip.188.com') to 'Gmail, Outlook, 163/126/188.com variants, and any standard server' to reduce padding while preserving distinctiveness.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('Check for new/unread messages, fetch content, search mailboxes, mark as read/unread, and send emails with attachments'), matching the score-3 anchor rather than the less-comprehensive score-2.

3 / 3

Completeness

Clearly answers 'what' with an action list but lacks a 'Use when...' clause or equivalent explicit trigger guidance; the 'Works with any IMAP/SMTP server...' phrase states compatibility, not when to invoke, so completeness is capped at 2 per the guidelines.

2 / 3

Trigger Term Quality

Covers natural user terms ('email', 'unread messages', 'send emails with attachments', 'search mailboxes') across read/send/search/check operations, matching good coverage rather than missing common variations.

3 / 3

Distinctiveness Conflict Risk

'Read and send email via IMAP/SMTP' with a named provider list carves a clear niche unlikely to conflict with other skills, matching the score-3 anchor.
