Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnly, non-destructive, non-idempotent), so the bar is lower; the description adds real context by stating 'never writes', the project scoping, and that output includes exact apply_edit_batch ops for fixing findings. It does not address the non-idempotent hint, but adds value beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The scoping note is front-loaded, which is good, but the second sentence is a sprawling checklist of a dozen critique criteria (rhythm, type ladder, B&W, flash safety, matte flicker, etc.) that is over-stuffed and mostly irrelevant to tool selection. It is not appropriately sized.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description correctly describes the return (a score, ranked findings with concrete fixes, and apply_edit_batch ops), which is what an agent needs. Coverage is nearly complete for a read-only tool of this complexity, with only the board/deep parameters left ambiguous.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 50%, and the description compensates by explaining the render-selection chain '(final, else preview; or asset_key)', which adds semantics beyond what the variant enum alone conveys. However, 'deep' and especially 'board' remain unexplained in both places.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('judge/critique') and resource ('the newest render of the current edit'), and clearly labels itself as READ-only scoring. It reads as the holistic editor-critique pass, distinct from the narrow audit_* siblings, though it never names them explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied ('like a demanding editor', checking an edit before finalizing) and the render-selection rule (final, else preview; or asset_key) is given. But there is no explicit when-to-use vs the many audit_*/analyze_* siblings and no stated exclusions or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
