pause_resume_activity

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

With no annotations provided, the description carries the full burden. It states the core state transition (running to paused, paused to running) but does not disclose edge cases, prerequisites (e.g., needing a currently active activity), or any potential side effects like what happens if no matching activity exists.

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, front-loaded sentence that says everything essential in nine words. No wasted words or filler, ideally concise.

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 state-toggle tool with one required enum parameter and two well-described optional disambiguators, the description plus schema is sufficient to guide invocation. It lacks explicit return-value or error information, but given the tool's low complexity, this is a minor gap rather than a critical omission.

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 already provides descriptions for type_name and activity_id (67% coverage), and the tool description reiterates the pause/resume distinction that maps to the action enum. However, the description adds no new parameter-level detail beyond the schema, so it does not significantly compensate for the undocumented action parameter.

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 specific verbs ('Pause', 'resume') with a clear resource ('activity') and target state ('running', 'paused'). It unambiguously distinguishes this tool from the sibling start_activity and stop_activity tools by focusing on pause/resume semantics.

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 provides explicit conditions for use: pause a running activity or resume a paused one. It does not explicitly mention alternatives or exclusions, but the conditional phrasing gives clear context for when to invoke the tool.

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