sophos_dns_update_location

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

Annotations already indicate this is not read-only (readOnlyHint=false) and not destructive (destructiveHint=false). The description adds value by clarifying the behavior of clearing ip_addresses or domain_names via empty arrays, which is beyond the annotation hints. However, there is a minor inconsistency: the description says 'empty array' while the schema says 'empty string', which could cause confusion.

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 concise, consisting of two short sentences. It is front-loaded with the core purpose and immediately provides a key usage note. Every sentence earns its place with no fluff.

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 tool with 11 parameters and no output schema, the description could provide more context about prerequisites (e.g., tenant_id must exist) or the effect of the update (e.g., returns the updated location). The given description is adequate but missing some completeness that would help an agent understand the full scope.

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?

The input schema has 11 parameters with 100% description coverage, so the schema already explains each parameter. The description only reiterates the clearing behavior already noted in schema descriptions for ip_addresses and domain_names. Thus, the description adds marginal semantic value 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?

The description clearly states the tool updates a DNS Protection location, with the specific verb 'Update' and resource 'DNS Protection location'. It distinguishes from sibling tools like sophos_dns_create_location and sophos_dns_get_location by focusing on updates, and adds a valuable usage note about clearing fields with empty arrays.

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 description implies usage for updating a location and provides a specific instruction for clearing fields, but it does not explicitly state when to use this tool versus alternatives like creating or getting a location. No exclusions or alternative tool names are mentioned.

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