announcement_trigger_active

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

With no annotations, the description must convey behavior. It states the tool retriggers and restarts from the beginning, but does not disclose side effects (e.g., error if no active announcement) or confirm it is non-destructive. Adequate but minimal.

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 that is concise, front-loaded, and contains no unnecessary words. It efficiently communicates the tool's purpose.

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?

Given the tool is simple (no parameters, no output schema), the description is nearly complete. It could mention that an active announcement must exist, but the context of 'currently active' implies this. Suffices for a basic action.

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?

There are no parameters, so the schema coverage is 100%. The description does not need to add parameter details, but it explains the action itself. Baseline score of 4 is appropriate as the description is clear.

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 action: retriggering the currently active announcement and specifying it starts from the beginning. It uses a specific verb ('retrigger') and resource ('active announcement'), effectively differentiating from sibling tools like announcement_trigger_next or announcement_trigger_cue.

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 implies usage for restarting the active announcement but lacks explicit guidance on when to use it versus alternatives. It does not mention when not to use or list prerequisites, leaving some ambiguity for an agent.

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