aap_update_group

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

Annotations already indicate readOnlyHint=false and destructiveHint=false. The description adds that this is a PATCH operation and returns JSON with updated group id and name. It does not disclose edge-case behavior like whether null fields clear values or if variables must be YAML, so it provides only modest additional context.

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?

The description is compact and front-loaded with the core purpose. The Args/Returns structure is standard and wastes no words. It could be slightly more informative without losing conciseness, but it is efficient.

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 0% schema description coverage and no output schema, the description is too thin for a tool with four parameters. It lacks parameter semantics, usage rules, and behavioral details such as what happens to existing fields when omitted. The description only covers the basic purpose and return format.

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 compensate for the lack of field-level documentation. It only says 'params (UpdateGroupInput): Fields to update,' which restates the obvious and provides no meaning beyond the schema's field names. It does not clarify group_id, variables, or description formats.

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 description states a specific action ('Update an existing AAP inventory group') with the HTTP method (PATCH). It clearly identifies the resource type (inventory group) and distinguishes it from create/delete operations among 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?

No guidance is given on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or compare with related tools such as create_group or delete_group. The only implicit usage is 'update an existing group,' which is not enough.

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