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.

The body is highly actionable with well-sequenced, validated workflows and real bundle scripts, but it carries redundant config/server content that could be trimmed or externalized for better token efficiency.

Suggestions

Trim or externalize the 'Configuration Reference' and 'Common Email Servers' table, since the body states configuration is pre-configured and the scripts load it automatically.

Move the provider server table into a separate reference file referenced one level deep to improve progressive disclosure.

Dimension	Reasoning	Score
Conciseness	Mostly efficient command documentation, but the 'Common Email Servers' table and 'Configuration Reference' duplicate information already conveyed and partly contradicted by the 'pre-configured' note, adding tokens Claude doesn't need.	3 / 5
Actionability	Fully executable commands with concrete flags, options, and copy-paste-ready examples covering send, HTML, attachments, multiple recipients, and multi-account usage.	5 / 5
Workflow Clarity	Clear sequencing with explicit validation checkpoints: the --confirmed gate and pre-send review for destructive send operations, plus the error-to-check-LobsterAI-Settings feedback loop for failures.	5 / 5
Progressive Disclosure	SKILL.md acts as an overview pointing to real bundle scripts (scripts/imap.js, scripts/smtp.js) one level deep, though the config and server tables are inlined rather than split into separate reference files.	4 / 5

Description

75%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.

The description is specific and distinct with concrete email actions and provider triggers, but it omits an explicit 'Use when...' clause, which caps completeness.

Suggestions

Add an explicit 'Use when...' clause (e.g., 'Use when the user wants to read, search, or send email via IMAP/SMTP') to satisfy the completeness 'when' requirement.

Include natural synonyms such as 'mail' or 'inbox' alongside 'email' and 'mailboxes' to broaden trigger-term coverage.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Check for new/unread messages, fetch content, search mailboxes, mark as read/unread, and send emails with attachments' — giving comprehensive coverage of the email domain.	5 / 5
Completeness	Clearly states what the skill does, but there is no 'Use when...' clause or equivalent explicit trigger guidance, capping completeness at 3 per the rubric guideline.	3 / 5
Trigger Term Quality	Strong natural terms ('email', 'new/unread messages', 'mailboxes', 'attachments') plus named providers (Gmail, Outlook, 163.com), but misses common synonyms like 'mail' or 'inbox' that users would say.	4 / 5
Distinctiveness Conflict Risk	A clear IMAP/SMTP email niche with named providers and protocol-specific triggers, giving minimal overlap risk with other skills.	5 / 5
