Quality

Content

85%

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

A concise, well-structured skill that efficiently communicates how to use Gemini CLI in one-shot mode. Its main weakness is incomplete actionability—it could benefit from listing available models or common model names, and providing a concrete example of JSON output format usage. The safety note about --yolo is appropriate but could briefly explain what it does.

Suggestions

Add 1-2 specific model names (e.g., `gemini-2.5-pro`, `gemini-2.5-flash`) so Claude knows valid values for `--model`

Provide a concrete example showing expected output for at least one command (e.g., the JSON output format)

Dimension	Reasoning	Score
Conciseness	Very lean and efficient. No unnecessary explanations of what Gemini is or how CLIs work. Every line provides actionable information Claude wouldn't inherently know.	3 / 3
Actionability	Provides concrete commands that are copy-paste ready, but lacks detail on available models, output format options, and what extensions commands are available. The auth note is vague ('follow the login flow').	2 / 3
Workflow Clarity	This is a simple, single-purpose skill (one-shot CLI usage). The single action is unambiguous, and the auth note provides a clear fallback path. No multi-step destructive operations require validation checkpoints.	3 / 3
Progressive Disclosure	For a simple skill under 50 lines with no need for external references, the content is well-organized into logical sections (quick start, extensions, notes). No bundle files are needed for this scope.	3 / 3

Description

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 (Gemini CLI) and lists broad task categories but lacks specificity in its actions and entirely omits guidance on when Claude should select this skill. The generic task terms (Q&A, summaries, generation) create overlap risk with other skills, and the absence of a 'Use when...' clause significantly hurts its utility for skill selection.

Suggestions

Add an explicit 'Use when...' clause, e.g., 'Use when the user wants to query Gemini from the command line, run one-shot prompts, or generate text via the Gemini CLI tool.'

Make the actions more concrete — specify what kinds of generation, what inputs it accepts (e.g., 'pipe file contents to Gemini for summarization'), and what distinguishes this from other text generation or summarization skills.

Include natural trigger terms users might say, such as 'gemini', 'ask gemini', 'gemini prompt', 'gemini command line', or 'google AI CLI'.

Dimension	Reasoning	Score
Specificity	Names the tool (Gemini CLI) and some actions (Q&A, summaries, generation), but these actions are broad and not very concrete — 'generation' is vague, and the list is not comprehensive about what specific tasks it performs.	2 / 3
Completeness	Describes what it does at a high level 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, so this scores a 1.	1 / 3
Trigger Term Quality	Includes 'Gemini CLI' and 'one-shot' as relevant keywords, plus general task types like 'Q&A' and 'summaries', but misses common user variations like 'gemini', 'ask gemini', 'LLM', 'AI query', or file-related trigger terms.	2 / 3
Distinctiveness Conflict Risk	'Gemini CLI' is a fairly distinct tool reference, but 'Q&A, summaries, and generation' are extremely broad tasks that could overlap with many other skills involving text generation or summarization.	2 / 3
