Quality

Discovery

32%

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 identifies the tool and its supported Google Workspace services but fails to describe any concrete actions or provide explicit trigger guidance for when Claude should use this skill. It reads more like a product tagline than a functional skill description, leaving Claude without clear signals for when to select it over other skills.

Suggestions

Add a 'Use when...' clause specifying trigger scenarios, e.g., 'Use when the user asks to send emails, manage calendar events, upload/download files from Drive, manage contacts, edit spreadsheets, or work with Google Docs.'

List concrete actions for each service, e.g., 'Send and read Gmail messages, create and manage Calendar events, upload and share Drive files, edit Sheets and Docs.'

Include common natural language variations users might say, such as 'schedule a meeting', 'check my email', 'share a file', 'Google Drive', 'Google Sheets'.

DimensionReasoningScore

Specificity

Names the domain (Google Workspace CLI) and lists the specific services (Gmail, Calendar, Drive, Contacts, Sheets, Docs), but does not describe concrete actions like 'send emails', 'create events', 'upload files', etc.

2 / 3

Completeness

Describes what it is (a Google Workspace CLI tool covering several services) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per rubric guidelines, missing 'Use when' caps completeness at 2, and the 'what' is also weak (no actions described), so this scores a 1.

1 / 3

Trigger Term Quality

Includes good product-name keywords (Gmail, Calendar, Drive, Sheets, Docs, Google Workspace) that users would naturally mention, but misses common action-oriented terms like 'send email', 'schedule meeting', 'upload file', 'create spreadsheet', or variations like 'Google Drive', 'Google Docs'.

2 / 3

Distinctiveness Conflict Risk

The mention of 'Google Workspace CLI' and specific service names provides some distinctiveness, but the breadth of six different services without specific actions could overlap with individual skills for email, calendar, file management, or spreadsheets.

Implementation

64%

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

This is a solid, highly actionable CLI reference skill with concrete, executable commands covering all major gog subcommands. Its main weaknesses are some verbosity (calendar color hex codes, HTML tag explanations Claude doesn't need) and the lack of explicit error-handling or validation steps in workflows. The structure is reasonable for a single-file skill but would benefit from offloading reference material.

Suggestions

Remove the HTML tag reference list (Claude already knows HTML) and the full calendar color hex-code table—just reference `gog calendar colors` as the source of truth.

Add brief error-handling guidance: what to do if auth fails, how to verify a send succeeded, or how to retry on transient errors.

Consider moving the detailed email formatting examples and calendar colors into a separate reference file to keep the main SKILL.md leaner.

DimensionReasoningScore

Conciseness

Mostly efficient with concrete commands, but the calendar colors section (listing all 11 hex codes) and some HTML tag explanations are unnecessary padding—Claude already knows HTML tags. The email formatting section is somewhat verbose with examples that could be trimmed.

2 / 3

Actionability

Excellent actionability—nearly every command is copy-paste ready with concrete flags, arguments, and realistic examples. The setup flow, Gmail send variants, Sheets operations, and heredoc examples are all fully executable.

3 / 3

Workflow Clarity

Setup is clearly sequenced (auth credentials → auth add → auth list), and the note to confirm before sending mail/creating events is good. However, there are no explicit validation or error-recovery steps—e.g., no guidance on what to do if auth fails or if a send command errors out.

2 / 3

Progressive Disclosure

Content is organized into logical sections (Setup, Common commands, Calendar Colors, Email Formatting, Notes) which aids scanning. However, the calendar colors table and email formatting examples could be split into separate reference files to keep the main skill leaner, and there are no bundle files to reference.
