Update Region

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

Discloses PATCH semantics and return formats beyond annotations (readOnlyHint false, idempotentHint true). Annotations indicate mutation and idempotency; description adds context on partial update behavior.

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?

Four sentences, well-structured, no unnecessary words. Front-loaded with purpose and semantics.

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?

Covers essential aspects: PATCH semantics, id requirement, optional fields, and output formats. Lacks detailed explanation of nested objects but schema partially compensates.

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 coverage is 50%; description only mentions 'id' and 'response_format' explicitly. Other parameters (e.g., name, slug, tags) are not explained beyond the schema's minimal descriptions.

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?

Clearly states 'Update an existing region in NetBox' with PATCH semantics, distinguishing it from create/delete/get 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?

Explicitly instructs to supply numeric 'id' and only fields to change, and notes that omitting a field leaves it unchanged. Provides output format options.

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