Semantic Search

semantic_search
Read-onlyIdempotent

Search across Apple Notes, Calendar, Reminders, and Mail by meaning. Understand natural language queries to find relevant results based on semantic similarity.

Instructions

Search across Apple app data by meaning, not just keywords.

Behavior3/5

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

Annotations already declare readOnlyHint, destructiveHint, idempotentHint. The description adds 'by meaning' but no further behavioral details (e.g., result ordering, pagination, scope). Adds minimal value beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded purpose, no wasted words. Appropriate for the tool's simplicity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema and description does not mention return format. With siblings providing specific searches, this cross-app tool could benefit from clarifying scope and output. Annotations are rich but not fully compensating.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 100% description coverage for all parameters, so schema already provides meaning. Description adds no additional parameter semantics or usage hints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it searches by meaning across Apple app data, distinguishing from keyword search. It implicitly covers multiple sources but does not explicitly differentiate from sibling per-app search tools like search_notes or search_events.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives (e.g., per-app searches). No explicit when/when-not or alternative tool references, which is critical given many sibling search tools.

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