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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context beyond that: it enumerates the fields returned (role, member count, Pro seat count), which matters because there is no output schema. It doesn't cover pagination or empty-result behavior.

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 sentences, zero filler: the first defines the operation and its return payload, the second gives the follow-up action. Front-loaded with the core purpose.

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 zero-param, read-only list tool with no output schema, the description covers what is returned and how to use it, which is most of what an agent needs. Minor gaps remain around ordering/pagination and the empty case, but nothing blocking.

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 tool takes zero parameters, so per the rubric the baseline is 4. The description's mention of org_id is about consuming output elsewhere, not about an input here, so no further parameter detail is needed.

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?

Specific verb (List) plus resource (organizations) with an explicit scope qualifier ('the user belongs to') and the exact payload returned: role, member count, Pro seat count. This clearly distinguishes it from the singular sibling get_organization and from list_teams/list_channels.

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?

It tells the agent what to do with the output ('Use org_id with create_flow_from_text or move_flow_to_organization'), which is genuine routing guidance. It does not, however, state when this tool is preferable to get_organization or when it should be skipped, so it stops short of full when/when-not coverage.

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