Search notes

search_notes
Read-only

Search user notes by substring, grouped by book, to find specific annotations and see each matching note with its highlighted passage.

Instructions

Search user notes (not highlights) by substring, grouped by book. Output shows the highlighted passage on the primary row and the matching note on a second line prefixed with ↳ note:.

Args: note: Substring to find inside note bodies. limit: Max annotations to return (1–500, default 50). offset: Annotations to skip, for paging. order_by: newest (default) or oldest first.

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already cover the read-only safety profile (readOnlyHint=true, openWorldHint=false), so the bar is lower. The description adds genuine behavioral value by disclosing the return layout: highlighted passage on the primary row and matching note on a second line prefixed with '↳ note:'. It does not discuss pagination limits or result caps beyond the limit arg.

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

Conciseness4/5

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

Front-loaded purpose followed by output format and then a compact args list; every sentence carries information. The docstring-style arg block with literal backticks is slightly awkward but not wasteful.

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

Completeness4/5

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

There is no output schema, so the description appropriately steps in to describe the returned row structure, and all parameters are documented. Combined with annotations covering read-only behavior, this is largely complete, though grouping/paging semantics of the output could be clearer.

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

Parameters4/5

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

Schema description coverage is 0%, so the description must carry semantics, and it documents all four params: note (substring inside note bodies), limit (1-500, default 50), offset (paging), and order_by (newest/oldest). The 1-500 range and default are constraints the bare schema does not convey, though the note param adds little beyond its name.

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

Purpose5/5

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

States a specific verb (search) and resource (notes), scope ('by substring, grouped by book'), and explicitly excludes highlights ('not highlights'), which separates it from the sibling search_annotations. An agent can identify the tool and its boundary without opening the schema.

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

Usage Guidelines3/5

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

The '(not highlights)' parenthetical hints at the boundary versus other annotation-searching tools, but there is no explicit when-to-use/when-not guidance, no named alternative, and no prerequisites. Usage is only implied.

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