Behavior4/5

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

Annotations already declare destructiveHint=true, so 'DESTRUCTIVE' is redundant. However, the description adds the behavioral requirement that confirm=True must be provided, which is a critical execution detail not in the annotations. It clarifies the scope by saying 'assignment'.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence with a warning and requirement. No fluff, front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a delete tool with a simple schema, the description covers the action, destructive nature, and mandatory confirm flag. It lacks explicit side-effect disclosure, but with annotations and output schema, it is adequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 0% description coverage. The description only explains the confirm parameter ('requires confirm=True'), while attribute_id and team_id are left to their names. The semantics are largely inferable from the tool name, but the description does not add meaningful guidance beyond the raw schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb 'Delete' and identifies the resource as 'a user attribute assignment for a specific team', distinguishing it from sibling tools like sigma_update_user_attribute_for_teams or sigma_delete_user_attribute_for_user.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides a crucial requirement (confirm=True) but does not explicitly state when to choose this over alternative set/update/delete variants. The intended use is implied by the name and destructive warning, but no exclusions or alternative tool references are given.

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