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

Annotations already declare destructiveHint=true, idempotentHint=false, and readOnlyHint=false, so the safety profile is carried by structured data. The description contributes one genuine behavioral detail beyond the schema (team names are normalized to lowercase), but says nothing about partial-update semantics, whether omitted fields are cleared or left intact, or permission requirements — relevant for 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?

Two short sentences, front-loaded with the mutation scope and the normalization caveat. Slightly awkward phrasing ('Rename a team or changing its description / auto-assignment'), but nothing is wasted.

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 mutation with no output schema and annotations covering the safety profile, the description tells the agent what fields can be changed but omits partial-update behavior, required permissions, and side effects of renaming. Adequate but with clear 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 description coverage is 0%, so the description must carry the load, and it names three of the four parameters (name, description, auto-assignment) and adds the lowercase normalization rule for name. It adds no meaning for team_id and does not clarify whether the update is partial or full replacement, leaving a real gap at low coverage.

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 (rename/change) and resource (team), and enumerates the three mutable fields, which lets an agent distinguish it from create_team, delete_team, and get_team. It does not, however, differentiate itself from the adjacent update_agents_in_team or update_agents_in_inbox, so it falls short of a 5.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no alternative is named. The only implicit signal is that the tool targets an existing team, which an agent must infer from 'update'. No prerequisites or preconditions are stated.

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