search_memory

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It adds useful context about search behavior ('each word is matched independently and ranked by relevance'), which goes beyond the basic purpose. However, it doesn't cover other important aspects like authentication needs, rate limits, error conditions, or what the output contains, leaving gaps for a tool with no annotation support.

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 perfectly concise and well-structured in a single sentence that front-loads the purpose and follows with specific usage guidance. Every word serves a purpose with no wasted text, making it easy to parse quickly.

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 that there's an output schema (which handles return values) but no annotations and 0% schema description coverage, the description provides adequate basic purpose and usage guidance but falls short on parameter explanations and behavioral details. For a search tool with 3 parameters, it should ideally provide more complete parameter semantics to compensate for the schema gaps.

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 schema description coverage is 0%, meaning none of the parameters have descriptions in the schema. The tool description mentions 'short keywords' which relates to the 'query' parameter, but doesn't explain the semantics of 'tags' or 'limit' parameters. This partial coverage doesn't adequately compensate for the complete lack of schema descriptions for a 3-parameter tool.

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 tool's purpose with the verb 'Search' and resource 'saved memories', making it immediately understandable. It distinguishes itself from siblings like 'list_memories' by specifying a search functionality, though it doesn't explicitly contrast with 'search_sessions' which might have similar search mechanics but different targets.

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 clear context on how to use the tool effectively ('Use short keywords, not natural language phrases'), which helps guide proper invocation. However, it lacks explicit guidance on when to choose this tool over alternatives like 'list_memories' or 'search_sessions', leaving some ambiguity in sibling differentiation.

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