pine_session_get

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

No annotations are provided, so the description carries the full burden. It states 'Get session details', indicating a read operation with no side effects. However, it does not disclose error handling, authentication requirements, rate limits, or what happens if the session_id is invalid. The description is adequate but not rich in behavioral context.

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, straightforward sentence without unnecessary words. It is front-loaded with the purpose. However, it could be slightly more informative about the output or limitations without becoming verbose.

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 tool has one parameter and an output schema, so the description is minimally complete. However, it does not explain the return values (though the output schema exists) or error scenarios. Given the simplicity of the tool, the description is adequate but could provide more context for proper selection among the many sibling tools.

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, meaning the parameter 'session_id' has no description in the schema. The tool description does not explain the format, source, or constraints of session_id. This provides no added meaning beyond the schema's type declaration.

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 'Get', the resource 'session details', and lists the fields 'state, title, and timestamps'. It distinguishes this tool from sibling tools like pine_session_list (which lists sessions) and pine_session_create/delete/url (which perform different actions).

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 implies this tool is used to retrieve details of a specific session, but it does not provide explicit guidance on when to use it versus alternatives like pine_session_list for listing sessions or pine_session_url for getting a URL. The context is clear but lacks exclusion or alternative recommendations.

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