A3.5/5.0
Behavior2/5

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

Annotations are absent, so the description must carry the full burden of behavioral disclosure. It indicates a mutating operation but does not disclose persistence, reversibility, required photo state, permissions, or whether repeated calls overwrite existing settings. This is a meaningful gap for a write tool.

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

Conciseness5/5

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

Single sentence, front-loaded with the verb and object, with field examples that clarify the settings payload. No filler or redundancy.

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

Completeness3/5

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

An output schema exists, so return values need no description, and the parameter list is small. Still, without annotations the description omits usage alternatives, mutational side effects, and value semantics for the arbitrary settings object. It is sufficient for a basic call but not fully self-contained.

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

Parameters3/5

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

Schema coverage is 0% and the settings object permits arbitrary additional properties. The description compensates partially by naming known valid adjustment keys, but it does not explain value units, ranges, or how photo_id should be provided. Meaningful but incomplete.

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

Purpose5/5

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

The description states a concrete operation — 'Set Develop adjustments directly on a photo' — and enumerates representative fields (Exposure2012, Clarity2012, Dehaze, Vibrance). This makes the tool's purpose clear and distinguishable from preset/copy operations.

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

Usage Guidelines3/5

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

The word 'directly' implies usage in contrast to applying a preset or copying settings, and the listed adjustment names suggest individual parametric editing. However, it never names alternatives such as apply_develop_preset or copy_develop_settings, nor states when not to use this tool, leaving routing to inference.

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