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

Beyond the annotations it discloses two non-obvious traits: ownership is preserved across the move, and the return is 'never refused on a quota.' It also names the authorization condition for acting on someone else's item. It stops short of saying what happens if the item is not currently in that team.

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 tight sentences, front-loaded with the effect, then parameter choice, then guarantees. No filler, though the 'Name one of your own items' sentence partly restates the schema's 'Instead of name' wording.

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 four-parameter, non-read-only tool with annotations covering idempotency and destructiveness, the description supplies the important unwritten behavior (ownership retention, no quota refusal, permission gate). Missing only failure modes for items not in the team.

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%, so the schema already documents id, name, kind and team. The description adds only the mutual-exclusivity framing and the permission gate on id, which is modest value over structured data. Baseline 3 applies.

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 opening clause gives a concrete verb and effect: taking an item out of a team and back under its owner. It is immediately distinguishable from most siblings, though the inverse tool team_share is never named, so the agent must infer the pairing.

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 gives a real selection rule between the two identity parameters (own item by name, or any team item by id if you may delete that kind of content), which is useful. But it never states when to prefer this over team_share or the delete tools, leaving the core when-to-use decision implicit.

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