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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'Remove' implies a destructive operation, it doesn't specify whether deletion is permanent, reversible, requires specific permissions, or has side effects. The confirmation message return is mentioned but not elaborated.

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 appropriately sized with a clear main statement followed by structured Args and Returns sections. Every sentence earns its place, though the 'Args' and 'Returns' labels could be integrated more naturally into flowing 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?

Given this is a destructive operation with no annotations, 0% schema coverage, but an output schema exists, the description is minimally adequate. It covers the basic purpose and parameter meaning but lacks important behavioral context about deletion consequences and usage guidelines relative to siblings.

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 adds the meaning of 'memory_id' as 'The unique identifier of the memory to delete', which provides essential context beyond the bare schema. However, it doesn't explain format, constraints, or where to obtain this identifier.

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 action ('Remove') and target resource ('a specific memory'), making the purpose immediately understandable. However, it doesn't differentiate this from the sibling tool 'clear_memories' which likely removes multiple memories, so it doesn't reach the highest score.

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 like 'clear_memories' (for bulk deletion) or other sibling tools. It simply states what the tool does without context about appropriate use cases or prerequisites.

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