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

Annotations already flag destructiveHint=true and idempotentHint=true, but the description adds the crucial blast-radius detail that a template change re-renders and reinstalls the signature of everyone in the group, which is exactly the context an agent needs before mutating. It stops short of stating reversibility or permission requirements.

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 tight sentences with no filler; the primary action comes first and the consequential side effect second. Every clause carries information.

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 destructive, no-output-schema mutation, the description covers the action and its main side effect, with parameters fully documented in the schema. The remaining gap is the combination semantics of name and template_id (mutually exclusive vs. both applied), which the agent must guess.

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%, so all three parameters are documented structurally, setting the baseline at 3. The description adds a bit of meaning to template_id by explaining its downstream re-render/reinstall effect, but says nothing about the id/name semantics beyond the schema.

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 two specific operations on a specific resource: rename a group, or repoint it at a different template. Combined with the title and the sibling set (create_group, delete_group, update_teammate), an agent can immediately tell this is the group-mutation tool.

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 described operations imply when to call it, but there is no explicit guidance on prerequisites or alternatives, and no statement about whether name and template_id may be supplied together or whether one is required beyond id. Usage is inferable rather than stated.

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