sophos_authenticate

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

With no annotations provided, the description carries full burden and discloses key behaviors: token management is automatic and refreshes are handled, and it returns 'success status and authentication state.' It could add detail about side effects or safety, but the given info is solid.

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 three sentences with no extraneous information. It front-loads the core purpose and efficiently covers usage guidance and behavior. Every sentence adds value.

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?

Given the tool's simplicity (no parameters, no output schema), the description covers all essential aspects: what it does, how token handling works, and its role as a first-step tool. It is complete for the context.

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 zero parameters, so schema description coverage is 100%. According to guidelines, baseline is 4 for 0 parameters. The description adds no parameter info, which is appropriate since there are none to describe.

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 explicitly states 'Authenticate to Sophos Central using OAuth2 client credentials and obtain a JWT access token,' which clearly identifies the verb and resource. It distinguishes itself from sibling tools that perform CRUD or management operations, as this is a prerequisite authentication step.

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 phrase 'Call this first to verify credentials are working' provides clear guidance on when to use the tool—before any other operations. However, it does not explicitly state when not to use it or mention alternatives, but for an authentication tool this is typically sufficient.

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