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 body is a tight, action-oriented overview: executable commands, a clear model/options matrix, and an explicit MEDIA-line delivery checklist, with detail correctly pushed to the bundled script. It respects Claude's competence while surfacing the non-obvious operational rules.

DimensionReasoningScore

Conciseness

The body is lean — a model table, copy-paste code blocks, an options table, and short operational notes (e.g. "The API key is pre-configured on this machine") that convey non-obvious facts Claude lacks; not a 2 because there is no redundant concept explanation or padding.

3 / 3

Actionability

Fully executable commands with real flags and defaults, e.g. "node {baseDir}/scripts/generate-image.js --prompt ... --filename ...", plus an options table with defaults; copy-paste ready, matching the executable-code anchor; not a 2 because the examples are complete rather than pseudocode.

3 / 3

Workflow Clarity

The single primary action (run the script) is unambiguous, and the post-generation delivery step is an explicit checklist ("You MUST include this exact MEDIA: line", "Do NOT read the generated image back"); not a 2 because the sequence and constraints are explicit, and the batch/multi-image case is generative rather than destructive so the validation cap does not apply.

3 / 3

Progressive Disclosure

SKILL.md is a well-organized overview (Prerequisites, Models, Generate, Edit, Options, Output) with one clearly signaled one-level-deep reference to the real bundle "scripts/generate-image.js"; not a 2 because content is appropriately split between the overview and the executable script rather than inlined or nested.

Description

100%

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 concise, specific, and complete — it names the concrete capabilities, lists three distinct models, and provides explicit natural-language triggers. It answers both what the skill does and when to use it without fluff.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ("All-in-one image generation", "edit image") and enumerates three specific named models ("Nano Banana (3.1 Flash)", "Nano Banana Pro (3 Pro)", "Nano Banana 2 (2.5 Flash)"), matching the anchor for listing multiple specific concrete actions; not a 2 because coverage is comprehensive rather than partial.

3 / 3

Completeness

Explicitly answers what it does (image generation/editing with the Nano Banana model family) and when to use it ("Triggers on ..."), satisfying both the 'what' and 'when' with explicit triggers; not a 2 because the 'when' is stated explicitly rather than implied.

3 / 3

Trigger Term Quality

"Triggers on \"generate image\", \"image generation\", \"nano banana\", \"edit image\"" provides good coverage of natural terms a user would say; not a 2 because it spans several common phrasings rather than a single keyword.

3 / 3

Distinctiveness Conflict Risk

The "nano banana" trigger carves out a clear niche tied to a specific model family, making mis-triggering unlikely; not a 2 because the distinct product-named triggers separate it from generic image skills.
