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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds genuinely useful non-annotation context: the private portal link is deliberately excluded from the response, and the returned member_id is the key for downstream assign_crew calls. Pagination/return format is still unstated.

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?

Purpose is front-loaded and the routing instructions are clear. The middle sentence explaining the film/edit/clip/publish ordering is domain flavor rather than actionable instruction, and it slightly dilutes an otherwise tight definition.

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, the description carries the burden of describing returns, and it does identify the key fields (member_id, name) and one notable omission (portal link). It stops short of describing the full record shape or ordering guarantees across roles.

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 coverage is 100% and the single role parameter carries an enum plus its own description, so the schema does the heavy lifting. The description's mention of editors/clippers/posters loosely maps to the enum values but adds no filtering syntax or default behavior beyond what the schema already says.

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 (list) and resource (production crew of the organization) and enumerates exactly what the resource contains (editors/monteurs, clippers, posters), so it is clearly distinguishable from siblings like list_models or list_assignments. An agent knows precisely what it will get back without opening the 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?

It names two alternatives with conditions: use the returned member_id (or name) with assign_crew, and fetch the private portal link via get_member_link instead of this tool. That is explicit routing for the follow-up actions, though it never states when not to call list_crew (e.g., versus other listing tools).

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