Agent Memories

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds value beyond annotations by disclosing OAuth/scoped credential and API key requirements and the $0.10 cost. No behavioral trait contradicts the annotations.

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?

Purpose is front-loaded, followed by usage guidance, alternative routing, and requirements in a compact form. Every clause contributes new information; no filler or redundant elaboration.

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 the input schema covering both parameters and an output schema present, the agent has all return and parameter details. The description fills the remaining gaps: when to prefer search, authentication needs, API key, and cost. This is complete for a read-only retrieval tool.

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 100%, so schema already documents both optional parameters. The description adds meaning to 'query' by stating it supports both semantic and keyword retrieval, which goes beyond the schema's 'Semantic focus' label. Limit semantics are left to the schema, which is sufficient.

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?

Description states a specific action and resource: retrieving authenticated user memories from Dayze Agent. It also distinguishes itself from sibling search by noting when search is preferred for event-first trip and calendar titles. This is more than a restatement of the name or title.

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?

It explicitly instructs passing a query for semantic/keyword retrieval and tells the agent to prefer search for event-first trip and calendar titles. It also discloses credential and API key prerequisites. This gives clear when-to-use and when-not-to-use guidance.

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