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

Beyond the destructiveHint/readOnlyHint annotations, it discloses non-obvious consequences: the transferred board's Pro features follow the new owner's plan, the original owner is demoted to editor rather than removed, and omitting confirm yields a read-only preview. These are exactly the side effects an agent needs before committing.

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 compact sentences, with the ownership outcome front-loaded and the confirm requirement placed last where it operates as a gate. No filler or restated title text.

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 3-parameter mutation with no output schema, it covers the action, its side effects, and the dry-run path. It does not say what the preview returns or what error surfaces when the target is not a member, which are minor gaps.

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 only 33%, so the description must compensate: it constrains newOwnerId to 'one of its members' and restates confirm's preview semantics. boardId is left undiscussed, but its meaning is unambiguous from the name.

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 description states a precise verb and resource ('hands a board the user owns to one of its members') and spells out the resulting state change: new member becomes owner, the user becomes an editor. This distinguishes it clearly from siblings like share_board, remove_member, and leave_board.

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 states the precondition (the user must own the board; the target must be a member) and the required invocation mode (confirm: true, otherwise a preview only). It never names alternative tools such as share_board for the non-ownership-sharing case, so the agent must infer that boundary.

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