timeline_operation

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

No annotations are provided, so the description carries full burden. It mentions performing operations but doesn't disclose behavioral traits such as required permissions, whether it affects presentation state, error conditions, or response format. This leaves significant gaps for a mutation tool with no safety hints.

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, efficient sentence that front-loads the core action. However, it could be more structured by explicitly listing the enum values or clarifying context, but it avoids unnecessary verbosity.

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 performs mutations with no annotations and no output schema, the description is incomplete. It lacks details on behavioral impact, error handling, or what constitutes 'active presentation', making it inadequate for safe and effective use by an agent.

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 100%, with the parameter 'operation' fully documented via enum and description. The description adds no additional meaning beyond implying the operations apply to a presentation timeline, which the schema already covers, so it meets the baseline for high schema coverage without compensating value.

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 the action ('perform timeline operation') and target ('on active presentation'), which clarifies the basic purpose. However, it's vague about what 'timeline operation' entails—though the enum in the schema provides specifics—and doesn't differentiate from sibling tools like 'focused_timeline_operation' or 'presentation_timeline_operation', leaving ambiguity about scope.

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 alternatives. With sibling tools like 'focused_timeline_operation' and 'presentation_timeline_operation' present, the description fails to specify if this applies to a default or specific presentation context, offering no usage context or exclusions.

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