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

No annotations are provided, so the description carries the full burden. It discloses the returned role taxonomy (owner/admin/user), which is genuinely useful, but says nothing about read-only safety, permissions required, pagination, or ordering. Moderate but incomplete 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?

A single compact sentence with the action front-loaded and no filler. Appropriate size for a one-parameter list tool, though it could have added one clause of usage context within the same brevity.

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 simple single-parameter read tool with a fully documented schema and no output schema, the description covers the essentials and even hints at the return shape via the role enumeration. Only minor gaps (no pagination or permission notes) 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% for the single board_id parameter, so the schema already carries full parameter documentation. The description adds no format or constraint detail beyond it, making the baseline 3 appropriate.

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 ('see') and resource ('all board members and their roles'), and enumerates the role values returned. It is clearly distinguishable from siblings like add_board_member, invite_board_member, and remove_board_member, though it does not name them explicitly.

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?

'Use this command to see all board members' implies the read use case but gives no conditions, prerequisites, or alternatives (e.g., when to prefer this over list_pending_invitations or list_boards). Usage is implied rather than stated.

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