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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds genuine value on top: it discloses the payload contents (email addresses plus smart-field values merged into templates) and the paginated nature of the result. It stops short of describing auto-pagination behavior, which lives only in the schema.

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?

Three tight sentences, front-loaded with the action and scope, then the domain definition, then pagination. Every sentence earns its place, though the trailing "(page/limit)" is mildly redundant given the schema and could be dropped.

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-shape explanation is not required, and the description still volunteers what a teammate record contains. Combined with full annotation coverage and a 100%-documented schema, the definition gives an agent enough to call it correctly; only the distinction from sibling list tools is left implicit.

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 100% and all five parameters are documented there, so the schema carries the load. The description's parenthetical "(page/limit)" merely echoes two schema fields and says nothing about auto_paginate or max_pages, so it adds no meaning beyond the structured data. Baseline 3 applies.

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?

States a specific verb and resource ("List the workspace's teammates") and goes further by defining what a teammate is — a managed person whose signature Scribe deploys, carrying email addresses and smart-field values. That definition distinguishes it from near-neighbors like list_signature_recipients and list_signature_installations without the agent having to open a schema.

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?

Usage is implied by the resource definition (listing teammates rather than recipients or installations), but the description never states when to reach for this tool versus list_signature_recipients, or how it relates to sync_teammates. It is adequate but leaves the routing inference entirely to the caller.

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