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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive behavior, so the safety profile is covered. The description adds that PermID corporate identity and CC BY 4.0 credit are included, which is useful output context but not deeper behavioral disclosure.

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 short and front-loads the scope statement before the attribution note. It is appropriately sized, though the first sentence is cryptic enough that its brevity sacrifices clarity.

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?

With no output schema and a single undocumented parameter, the description is too sparse to tell an agent what the "book" contains, how results are structured, or what the name parameter requires. It supplies a partial data-provenance note but leaves core invocation and return expectations incomplete.

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?

The sole parameter "name" has no schema description (0% coverage) and the description does not explain what the name represents, its expected format, or whether it identifies a holder or company. The phrase "A holder's whole book" only loosely implies the name is a holder identifier.

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 largely restates the title ("A holder's WHOLE book") without a clear verb or resource explanation. It adds scope ("across every office. Founder and up") and mentions PermID attribution, but an agent still cannot tell precisely what the tool returns or how it differs from holder_read.

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?

No explicit guidance is given on when to use this tool versus alternatives such as holder_read. The phrase "WHOLE book" implies comprehensiveness but does not state conditions, exclusions, or sibling comparisons.

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