Conciseness

The ~66-line body is telegraphic throughout — "Draft 1K, iterate small prompt diffs, final 4K", "Do not open/read images; report saved path", "command -v uv" — with zero explanation of concepts Claude already knows. Matches the lean-and-efficient 5 anchor; nothing to trim, so above 4.

Actionability

Quick Start gives four copy-paste-ready commands covering the common cases (generate, edit, compose, multi-turn chat), and all flags, resolution values, aspect ratios, filename pattern, and preflight checks are concrete and verified against the actual bundle scripts. Fully executable guidance covering the common cases matches the 5 anchor.

Workflow Clarity

A clear sequence is present ("Draft 1K, iterate small prompt diffs, final 4K"; "For edits, keep same --input-image until final") with explicit preflight checkpoints, but there is no error-recovery feedback loop — the Common Failures section lists causes ("Quota/permission/403 errors") without remedies. Below 5 for the missing feedback loop; above 3 because both sequence and checkpoints are explicit.

Progressive Disclosure

The body is a clear overview with well-organized sections and a Scripts inventory indexing five real one-level-deep bundle files (all five exist in scripts/ and match their documented interfaces); no API detail is dumped inline and references are clearly signaled. Matches the clear-overview anchor; nothing is inlined that belongs in a separate file.

Specificity

"Generate/edit images with Nano Banana Pro (Gemini 3 Pro Image)" plus "logos, stickers, mockups, style transfer, multi-image composition, and multi-turn refinement" lists several specific capabilities with only minor gaps. It falls below the 5 anchor because the 'incl' list is a set of use-case nouns rather than a fully comprehensive list of concrete actions, and above 3 because coverage extends well beyond 1-2 actions.

Completeness

Both parts are explicit: the what is "Generate/edit images with Nano Banana Pro (Gemini 3 Pro Image)" and the when is "Use for image creation or modification incl logos, stickers, mockups, style transfer, multi-image composition, and multi-turn refinement" — a clear 'Use when...' clause with concrete trigger phrases. Above 4 because the when clause is explicit and specific rather than vague or weakly implied.

Trigger Term Quality

Natural user phrases like "image creation or modification", "logos", "stickers", "mockups", and "style transfer" give good keyword coverage. Missing a few common synonyms and extensions ("photo", "picture", "draw", ".png"), so below 5; coverage is solid rather than partial, so above 3.

Distinctiveness Conflict Risk

Naming the specific model "Nano Banana Pro (Gemini 3 Pro Image)" establishes a clear niche, but generic triggers like "image creation", "logos", and "mockups" would also match other image-generation skills, creating minor overlap risk. Mostly distinct (4) rather than minimal-conflict (5), but clearly more anchored than the somewhat-specific 3 anchor.
