Quality

Content

100%

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

The content is lean, fully actionable, and well-structured with an explicit bootstrap sequence and error-recovery feedback loops, assuming Claude's competence throughout.

DimensionReasoningScore

Conciseness

The body is dense and information-rich — tables for dispatch, models, env vars, and error codes with executable bash examples and no padding explaining basic concepts — assuming Claude's competence with every token earning its place.

3 / 3

Actionability

Provides fully executable commands (e.g., 'agy-agent --grounded "Latest stable version of X?"', 'agy-agent --resume "Follow-up"'), exact timeout values (600000), concrete env vars, and exit-code-to-recovery mappings that are copy-paste ready.

3 / 3

Workflow Clarity

A MANDATORY sequenced bootstrap (capability pinning, PATH check) plus an Error Handling table mapping exit codes to explicit recovery actions (124 -> raise AGY_TIMEOUT; auth_error -> run agy interactively) provides clear checkpoints and feedback loops.

3 / 3

Progressive Disclosure

A single well-organized SKILL.md with clear sections and a clearly signaled one-level reference to gotchas.md; as a simple single-purpose CLI-wrapper skill with no bundle files, the well-organized structure satisfies progressive disclosure per the simple-skills scoring note.

Description

67%

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, naming concrete capabilities and a clear niche, but it lacks an explicit 'Use when...' clause and relies somewhat on technical jargon over natural trigger terms.

Suggestions

Add an explicit 'Use when ...' clause to the description (e.g., 'Use when you need fresh web facts with citations via Gemini, or want Gemini 3.x Pro without the OpenCode routing layer') to lift completeness to 3.

Replace some model-identifier jargon ('gemini-3.x models', 'Antigravity (agy) CLI') with natural phrasing users would actually say to improve trigger term quality.

DimensionReasoningScore

Specificity

Names multiple concrete capabilities — 'Direct Google Gemini bridge via the Antigravity (agy) CLI', 'Google Search grounding (via --grounded)', 'gemini-3.x models', 'no API key' — matching the anchor for listing several specific concrete actions.

3 / 3

Completeness

It clearly answers 'what does this do' but provides no explicit 'Use when...' trigger guidance in the description field, so 'when' is only implied via the separate triggers list — capping completeness at 2 per the rubric guideline.

2 / 3

Trigger Term Quality

The description contains relevant keywords ('Google Gemini', 'Google Search grounding') but leans on technical jargon and model identifiers ('Antigravity (agy) CLI', 'gemini-3.x') rather than broad natural phrasing a user would say, missing common variations.

2 / 3

Distinctiveness Conflict Risk

The 'without the OpenCode layer' framing and the direct-bridge niche carve a clear, distinct purpose unlikely to conflict with generic or opencode-routed skills.
