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

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=true; the description goes beyond them with the auth requirement, the directory-managed refusal case, and the blast-radius note that id-based references are unaffected. The remaining gap is that it never says what the call returns, though no output schema exists to cover that either.

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?

Four short sentences, front-loaded with the action and followed by the consequences an agent most needs (references intact, refusal condition, auth). Nothing is redundant with the title or schema.

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 two-parameter mutation with full schema coverage and rich annotations, the description covers scope, auth, and failure mode adequately. The one omission is return behavior, which matters slightly more here because there is no output schema to defer to.

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%, and the schema already states the name must be unique among live teams and that team_id comes from list_teams. The description adds no parameter-level detail beyond that, so the baseline of 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?

States a specific verb and resource ("Rename a team") and immediately bounds the effect: escalation paths reference teams by id, so references do not break. That is enough to distinguish it from archive_team, create_team, and get_team without opening any 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?

Gives an explicit exclusion ("Refused for a team your directory manages") and a prerequisite ("Requires a personal API key"), which tells the agent when the call will fail before it attempts it. It does not name an alternative tool, but no sibling offers a competing rename path.

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