entry_timeline

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 a generic 'Get' operation and does not mention read-only status, pagination, date range handling, or any side effects. The description offers minimal transparency beyond the basic action.

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 with no redundancy, but it is under-specified for a tool with 5 parameters and unclear output. It fails to explain what 'timeline' means, making the description too short to be appropriately sized.

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 lack of an output schema and the presence of multiple sibling tools, the description is incomplete. It does not describe the return format, what a timeline specifically provides, or how it relates to entry_list. This leaves significant gaps for an agent trying to select and invoke the tool correctly.

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 coverage is 100% with basic descriptions for all parameters, but the description adds no extra meaning beyond what is already in the schema. The date range and filter lists are implied by the schema, and the description does not clarify their usage or semantics further.

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 'Get' and resource 'timeline of entries', clearly indicating what the tool does. However, 'timeline' is ambiguous and does not distinguish this from sibling tools like entry_list, which also retrieves entries.

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 provides no guidance on when to use this tool versus alternatives. It does not mention filters, sorting, or any specific use case that would differentiate it from entry_list or other entry-related tools.

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