timeline_operation

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

No annotations are provided, so the description must disclose behavioral traits. It only states that an operation is performed without mentioning side effects, required permissions, or state changes. For a mutating tool, this is insufficient.

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, short sentence that efficiently conveys the core functionality. However, it lacks structure (e.g., bullet points or separation of details) that could improve readability for more complex tools.

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 tool with one simple parameter and no output schema, the description is minimally adequate. Given the large number of sibling timeline operation tools, it would benefit from clarifying the scope (e.g., 'active presentation' vs 'focused') to avoid ambiguity.

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 input schema covers 100% of parameter semantics with an enum description listing the three operations. The tool description repeats this list without adding new meaning, so it provides no value beyond the schema.

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 verb (perform), resource (timeline operation), and the specific operations (play, pause, rewind) on the active presentation. It distinguishes the tool from siblings by targeting the 'active presentation,' but lacks explicit differentiation from similar timeline operation tools like 'focused_timeline_operation'.

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 on when to use this tool versus alternatives such as 'announcement_timeline_operation' or 'focused_timeline_operation'. The description does not provide context for appropriate usage or mention any prerequisites or constraints.

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