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

Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds bulk-execution behavior beyond annotations, but does not describe return format, missing-ID handling, or account selection. This adds value but not rich behavioral context.

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 two short sentences, front-loaded with the core purpose, and contains no filler. The bulk-support sentence is informative and earns its place.

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?

For a simple read tool with good annotations, the description covers the main action and bulk behavior. However, the lack of output schema, 0% parameter coverage, and ambiguity around note_id/note_ids/account leave notable gaps for full autonomous invocation.

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 0%, so the description must compensate. It explains note_id and note_ids ('Bulk support'), but it does not describe the 'account' parameter or clarify whether note_ids is an alternative to or a supplement for the required note_id.

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 returns a Google Keep note/list by ID, which is a specific verb+resource+scope. The 'pelo id' wording differentiates it from search-oriented siblings like keep_find and from mutation tools.

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 bulk support note ('accepts note_ids for batched execution') gives some usage context, and the purpose implies when to use the tool. However, it does not explicitly contrast with alternatives like keep_find or mention when not to use this tool.

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