Sueño de un ciclo

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

No annotations are provided, so the description carries full burden. It only states the basic action without disclosing read-only nature, authentication needs, error behavior (e.g., if cycleId is invalid), or any side effects. This lack of behavioral context is a significant gap.

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 sentence, efficient and front-loaded. No unnecessary words. However, it might be too brief and could benefit from an English version for broader compatibility.

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, no annotations, and only one parameter, the description is minimal. It lacks information about the return format, possible errors, or how the cycleId relates to other tools. For a simple tool, this is barely adequate.

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 100%, and the description adds no additional meaning beyond 'ID del ciclo'. The parameter is already clearly named and described. No extra context is provided, so baseline score applies.

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 retrieves a sleep session for a specific cycle, using a verb and resource. It distinguishes from siblings like get_sleep_by_id (which gets sleep by its own ID) and get_sleeps (lists sleeps). However, the Spanish language may reduce clarity for non-Spanish agents.

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?

No guidance on when to use this tool versus alternatives like get_sleep_by_id or get_cycle_by_id. The context of 'when' is implied (when you have a cycleId), but no exclusions or prerequisites are given.

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