Behavior2/5

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

States mutation action and scope, but lacks details on error handling, idempotency, side effects on existing presets, or behavior when optional fields are omitted. Annotations absent so description bears full burden.

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

Conciseness3/5

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

One short sentence, no filler. However, it is too minimal given the tool complexity; missing key details reduces its value.

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

Completeness2/5

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

Does not explain behavior of optional fields, error scenarios, or impact on existing signatures. Lacks completeness for a mutation tool with 6 parameters.

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

Parameters2/5

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

Groups parameters as 'datos' and 'imagen' but does not explain individual fields (e.g., DNI format, CUIL constraints). Schema coverage 0% and description fails to compensate.

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

Purpose4/5

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

Description states the tool modifies data and/or image of a preset, clearly distinguishing it from create, delete, and list siblings. However, it could be more explicit about the specific fields.

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

Usage Guidelines2/5

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

Only mentions the 'write' scope requirement. No guidance on when to use vs alternatives like create_preset or list_presets, nor prerequisites like preset existence.

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