unpin_memory

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It indicates the operation is destructive (removing a pin), mentions possible not_found result, but does not clarify whether the memory is deleted or simply unpinned, nor does it state authorization or side effects.

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 concise with only two sentences plus an Args section. It is front-loaded with the purpose and includes parameter and return info. No unnecessary text.

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?

With no output schema provided in the input (though context signals indicate it exists), the description mentions the return shape (JSON confirmation or not_found). For a simple single-parameter tool, this is reasonably complete, but could still benefit from clarifying whether 'remove' means deletion or just unpinning.

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 0%, so the description must compensate. It explains the memory_id parameter as 'The ID of the memory to unpin', which adds clear meaning beyond the schema's minimal 'Memory Id' title. This is good coverage given only one parameter.

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 'Remove' and the resource 'pinned memory from the thalamic buffer'. It also mentions the expected return value (JSON confirmation or not_found). This distinguishes it from siblings like pin_memory, but doesn't fully differentiate from related tools like forget.

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 does not provide any guidance on when to use this tool vs. alternatives such as forget or pin_memory. It lacks context about prerequisites (e.g., memory must be pinned first) or scenarios where using this tool is appropriate.

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