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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered. The description adds real effect-level context beyond that: the transfer brings current content, retained history and sharing, and the former owner is downgraded to editor — exactly the kind of consequence an agent needs before invoking a destructive mutation.

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?

Three short sentences, no filler. The action and its acceptance scope come first, followed by consequences, then the input prerequisites — a sensible front-loaded order.

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 and only annotations for the safety profile, the description supplies the ownership/effect semantics an agent needs. It could say more about failure modes (e.g., stale revision) but is adequate for a single-purpose mutation.

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 0% and all three parameters are required, so the description carries the burden. It explains that 'revision' must be current and where 'terms' comes from (the transfer review), but says nothing about the 64-character terms format or which transfer the 'id' identifies, leaving the schema to imply the rest.

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 precise verb+resource ('Accept a transfer offered to this authenticated account') and the scope of what is being accepted. The verb cleanly separates it from decline_space_transfer, cancel_space_transfer, and request_space_transfer among the siblings.

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?

The description establishes the precondition ('offered to this authenticated account') and the required inputs ('the current revision and terms from the transfer review'), which tells an agent when the call is valid. It does not explicitly contrast with decline/cancel alternatives, so it stops short of a 5.

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