event_toggle_pause

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states 'of a playing event instance,' implying a precondition, but doesn't explain what happens if the event isn't playing, whether the return state is disclosed, or what the actual toggle behavior is (pause vs. resume). Minimal context is added beyond the tool name.

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 brief—a single lead sentence stating the purpose and a one-line parameter spec. Every word earns its place and there's no extraneous filler. Slightly more behavioral context might be desired, but for what it attempts, it is efficient.

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?

This is a simple tool (1 required param, no output schema, no enums), so the bar for completeness is lower. The description covers the purpose and input format. However, it's missing context on return values or state outcomes, and the behavior on non-playing events is ambiguous. Given the low complexity, it's adequate but not thorough.

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?

Schema description coverage is 0%, so the description must compensate. It does add value by specifying the target format as 'event:// path or {guid},' which clarifies the accepted input. However, it doesn't explain the difference between the two formats or constrain them further. This partial compensation from the description is adequate for a single-parameter tool.

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 ('Toggle') + resource ('pause state of a playing event instance'), which clearly communicates the action. It's mostly clear but slightly tautological ('toggle the pause state') and doesn't explicitly contrast with siblings like event_play or event_stop, though the toggle semantics are inferable.

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 versus siblings like event_play, event_stop, event_key_off, or event_return_to_start. The scope is implied only by the word 'toggle' (requiring an already-playing instance), but no explicit when/when-not guidance or alternative naming is given.

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