modify_group

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

No annotations are supplied, so the description carries the full behavioral burden. It does disclose one useful trait — an error is returned if the group is not found — but says nothing about required authorization, whether unspecified attributes are preserved or wiped, or whether changes are reversible.

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?

Front-loaded with the verb+resource and backed by a concrete example, but the second sentence ('Updates group information including description, managed by settings, and other attributes') largely restates the first while adding only vague filler.

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?

This is a mutation tool with zero annotations, no output schema, and an open-ended nested object parameter. The description should therefore explain valid attribute keys, permission requirements, and mutation semantics, but covers only the not-found error.

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 both parameters are documented, establishing a baseline of 3. The description adds marginal value by naming a sample attribute key ('description') and showing the expected shape of the attributes dictionary, but never enumerates which attribute keys are valid for a nested object.

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 (modify) and resource (group), and the example clarifies that it patches attributes on an existing group. It is distinguishable from create_group/delete_group/get_group by name and example, though the description never explicitly contrasts itself with those 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?

There is no statement of when to use this versus create_group, add_group_member, or modify_user, nor any prerequisite such as required permissions. The example shows one invocation form but does not establish usage conditions or exclusions.

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