Crear preset de firma

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

No annotations are provided, so the description carries full burden. It discloses the need for 'write' scope and that the image is mandatory. However, it does not elaborate on potential side effects, idempotency, or error conditions. While not misleading, it lacks depth.

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 description consists of three concise, front-loaded sentences with no redundant information. Every word adds value, making it easy to read.

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?

Given the tool has 5 parameters with only one explained, no output schema, and no annotation support, the description leaves significant gaps. It does not clarify the relationship between parameters, the return value, or how the preset is stored (user vs studio level).

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 description coverage is only 20%, yet the description only adds context for the signatureImageBase64 parameter (mandatory, base64). The remaining parameters (firstName, lastName, dni, cuil) are not explained, leaving their purpose ambiguous.

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?

The description clearly states that the tool saves a signature in the library, which aligns with the tool name and title. It also specifies the mandatory requirement for the base64 PNG image. Among siblings like delete, update, and list signature presets, this tool's purpose is distinct.

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?

The description mentions a prerequisite (requires 'write' scope) but does not explicitly state when to use this tool versus alternatives like update_signature_preset or list_signature_presets. Usage context is only implied through the verb 'creates'.

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