fijar_objetivo_junta

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

No annotations are provided, so the description carries the full behavioral burden. It adds the nuance that the position is a 'target' (objetivo) rather than a direct instantaneous set, and mentions units, but it does not disclose whether the command triggers motion, requires a running simulation, or has any side effects. This is insufficient transparency for a mutation tool in a robotics context.

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 is a single, well-structured sentence that immediately states the purpose and includes a useful parenthetical about units. There is no redundant phrasing or filler, and every word contributes to understanding the tool's core function.

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 rich set of sibling tools (fijar_posicion, fijar_velocidad_junta, etc.) and the presence of an output schema, the description is too sparse to be contextually complete. It lacks guidance on how to select this tool, what the 'junta' parameter refers to, and the behavior when commands are issued. While the output schema reduces the need to describe return values, the description still misses critical selection and usage context.

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 0%, so the description must compensate. It clarifies that 'posicion' is measured in radians or meters, but provides no explanation of the 'junta' parameter (e.g., name, ID, or index) and does not specify which joint types use which units. This is minimal added meaning beyond the raw schema types.

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 the tool's action: 'Fija la posición objetivo de una articulación' (sets the target position of a joint). It uses a specific verb and resource, and the phrase 'articulación' differentiates it from sibling tools like 'fijar_posicion' which likely sets object positions. The parenthetical '(radianes o metros)' further clarifies the semantic scope.

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 implies usage by naming the exact operation (setting a joint's target position) but offers no explicit guidance on when to choose this tool over alternatives like 'fijar_posicion' or 'fijar_velocidad_junta'. There are no exclusions or alternative references, leaving the agent to infer the appropriate context from the tool name and resource.

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