duplicate_timeline

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

With no annotations, the description should disclose behavioral traits. It mentions duplication but omits any potential side effects, such as whether the current timeline selection changes or if the duplicated timeline is automatically opened. The output schema exists but its content is not described.

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 concise with no superfluous words. Two short sentences and a bullet-style argument list convey the core information efficiently.

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?

The description is adequate for a simple operation with one optional parameter and an output schema, but it lacks details such as the naming convention of the duplicated timeline (e.g., appends 'Copy') or confirmation of the return value.

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 has 0% description coverage, so the description adds needed context: the 'name' parameter is optional and defaults to the current timeline. This clarifies usage beyond the schema, though it could specify the format of the name (e.g., full path or simple name).

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 tool duplicates a timeline, with a specific verb and resource. It distinguishes itself from sibling tools like delete_timeline or export_timeline, though it does not explicitly contrast with them.

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 explains when to use the optional name parameter, but it does not provide guidance on when not to use this tool or suggest alternatives, such as create_empty_timeline for a different use case.

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