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

Annotations only declare readOnly/idempotent/non-destructive, and the description adds genuine behavioral context: access is evaluated per request via membership/product access/resource sharing, revocation mechanics, sharing propagation rules, owner-only sharing changes, origin/CSRF requirements for grants, and a 'private, no-store' response policy. Much of it is about sharing/revocation rather than listing, but it is real disclosure beyond the annotations and does not contradict them.

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 definition is long and front-loads a misleading scope claim, then spends most of its length on sharing/revocation/grant mechanics that are tangential to a read-only list operation. Several sentences do not earn their place for this tool's task.

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 two-parameter, no-output-schema list tool the description is verbose yet off-target: it never explains what a returned collection listing contains or references pagination behavior, while over-explaining unrelated sharing semantics. Minimum viability is met but the relevant gaps remain.

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%: 'after' (pagination cursor) and 'organization_id' (with list_knowledge_teams provenance and OKFIndex requirement) are fully documented in the schema. The description adds nothing about either parameter, so the baseline of 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?

The only purpose sentence is "List collections in your personal account," which directly conflicts with the tool name (team_list_collections) and the required organization_id parameter, implying team/organization scope. The verb+resource is present but the scope statement is misleading, so an agent cannot cleanly tell what this lists versus list_collections.

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 explicit when-to-use guidance and no mention of the obvious sibling list_collections or any other alternative. The description discusses access semantics but never states the condition that should make an agent pick this tool over the non-team variant.

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