resume_thread

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

Annotations already indicate this is a mutation (readOnlyHint=false) and non-destructive (destructiveHint=false). The description adds nothing beyond the verb 'resume' – it does not disclose side effects, required permissions, or what happens to the thread's state. With annotations present, the bar is lower, but the description still fails to add meaningful behavioral 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?

A single sentence with no redundancy. It is appropriately concise for the tool's simplicity, and the verb is front-loaded. No waste.

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 simple mutation with one parameter, the description is minimal but incomplete. It lacks information about expected outcomes, error conditions, or any prerequisites. Given no output schema and no usage guidance, an agent cannot fully understand what will happen when the tool is called.

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 schema has zero description coverage for the single parameter threadId. The description does not explain what threadId refers to (e.g., a valid thread ID, format, or how to obtain it). Since the description is the only source of parameter meaning, this is a significant gap.

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 states a clear verb ('Resume') and resource ('a paused Freebuff thread'), which identifies the operation unambiguously. It is distinct from siblings like stop_thread or get_thread, though it doesn't explicitly name the alternative. The phrasing is specific enough to convey the action.

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?

There is no guidance on when to use this tool versus alternatives, no prerequisites mentioned (e.g., thread must be paused), and no exclusions or context about typical use cases. The description implies use when a thread is paused, but it is left to the agent to infer.

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