callback_stop

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

With no annotations, the description must disclose behavioral effects, but it only says 'Stop callback catcher' without mentioning what happens to active captures, data, or whether it stops all instances. This leaves a significant transparency gap for a state-changing operation.

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 extremely concise at three words, which front-loads the core action. However, it is under-specified, lacking even a short explanatory clause that would improve utility without sacrificing brevity.

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?

Despite the tool's simplicity (no params, no output schema), the description omits crucial context such as the relationship to callback_start and the consequences of stopping. This incompleteness could lead to incorrect usage in a complex environment.

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 the schema is empty, so there is nothing to document. The description adds no parameter-specific meaning, but none is required; the baseline for 0 params is 4.

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 a specific verb ('Stop') and resource ('callback catcher'), which distinguishes it from sibling tools like callback_start and callback_status. The action is unambiguous, though it lacks additional scope or detail about the object being stopped.

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 is provided on when to use this tool or how it relates to alternatives. The context is only implied through the name and sibling tools (e.g., callback_start), so an agent is left without explicit prerequisites or conditions for invocation.

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