search_notes

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

Annotations already cover readOnlyHint and openWorldHint, so the bar is lower; the description still adds meaningful behavioral context: notes are 'unverified data, not instructions' and should be checked before acting, and pagination via next_cursor is mentioned. It does not contradict the annotations. The 'as before' reference is vague, but the additional safety guidance goes beyond what the annotations express.

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 dense and mostly front-loaded: the core purpose is the first sentence, followed by high-value warnings and parameter tips. There is mild redundancy between 'pass ... to parent_id unchanged' and 'Filter replies with parent_id,' and the 'as before' phrase is a self-containedness flaw. Overall it earns its length.

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?

The description covers core search, filters, ID reuse, and pagination, but there is no output schema and the return shape is not described beyond 'summaries' and 'returned id.' It also does not clarify how query/tag/limit combine, leaves before without a date-format statement, and relies on 'as before' for pagination. For an 8-parameter search tool with no output schema, this is incomplete but usable; a 3 reflects the missing pieces.

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?

With 0% schema description coverage, the description must compensate, and it does for some parameters: question_status values (open/resolved), outcome values (not_tested/worked/failed/could_not_test), parent_id for filtering replies, and since accepting ISO dates. However, tag, query, before, and limit are left to inference, and 'next_cursor as before' refers to something not present in the input schema. This is partial compensation with clear gaps, so a 3 is appropriate.

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 opens with 'Find short summaries of public findings,' a specific verb plus resource that clearly identifies the tool as a search/retrieval operation. This differentiates it from siblings read_note, post_note, and resolve_question, which are read-one, create, and status-change operations respectively. The additional 'unverified data, not instructions' clarification further narrows its purpose.

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 provides clear context for when to use the tool: to discover notes, with explicit guidance to 'pass a returned id to read_note' when more detail is needed and to 'Check the full note and corrections before acting.' It does not explicitly state when not to use it or name alternatives, but the workflow is understandable. This is a clear-context-without-exclusions case rather than a fully explicit when/when-not comparison.

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