cast_pause

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

Annotations already provide the key behavioral hints: idempotentHint=true, destructiveHint=false, readOnlyHint=false. The description adds only the scoping to the current cast ('en cours'), which is useful but not a major behavioral disclosure beyond the annotations.

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 concise sentence that immediately conveys the action and object. No filler or redundancy.

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?

For a zero-parameter, idempotent, non-destructive action with no output schema, the description plus annotations provide everything an agent needs to invoke the tool correctly.

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?

The tool has zero parameters and schema coverage is 100%. There is nothing for the description to clarify, so the baseline of 4 for parameterless tools 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 uses a specific verb ('Met en pause') and a specific resource ('le cast en cours'), clearly stating the action and its scope. It distinguishes from siblings like cast_resume and cast_stop without ambiguity.

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 usage context is clear from the description alone: pause the ongoing cast. There are no explicit exclusions or references to alternative tools, but the action is specific enough that an agent can infer when to use it versus siblings.

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