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

Annotations already declare readOnly, idempotent and non-destructive, but the description adds real behavioral context beyond them: stored evidence is frozen and no recapture, inference, or catalogue update occurs. That directly answers the 'what side effects does this trigger' question. It does not mention pagination limits or exhaustion behavior, keeping it short of a 5.

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?

Two tight sentences with the core action front-loaded, followed by a clarification of side effects. The second clause is slightly jargon-heavy but every word carries information about behavior.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. However, with two fully undocumented paging parameters and no routing guidance against get_notebook_entry, an agent is left to guess how to page correctly.

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% for two parameters (limit, cursor), so the schema gives no guidance on their meaning. The description only hints at paging through the verb 'Page' and never explains the cursor contract, limit bounds, or what a returned cursor means, so it fails to compensate for the coverage gap.

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 names a concrete verb-plus-resource ('Page your active saved notebook captures'), so an agent knows this retrieves multiple stored notebook entries rather than a single one. It stops short of explicitly naming the sibling get_notebook_entry, so differentiation is left to inference.

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?

There is no when-to-use guidance and no mention of the alternative get_notebook_entry for fetching one capture. The word 'Page' weakly implies iterative retrieval, but nothing states when this tool is the right choice versus search_pools or get_notebook_entry.

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