sophos_authenticate

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

Adds context beyond annotations by stating the token is managed automatically and refreshed. Annotations indicate readOnlyHint=true and destructiveHint=false, and the description does not contradict these.

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?

Three sentences, front-loaded with action, no wasted words. 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?

Returns success status and authentication state are mentioned; no output schema exists. Given the tool's simplicity, this is reasonably complete, but could specify what success/failure looks like.

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?

No parameters exist (schema coverage 100%), so baseline 4 applies. The description adds meaning by explaining the OAuth2 client credentials usage and token behavior.

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 it authenticates to Sophos Central using OAuth2 and obtains a JWT token. It distinguishes itself from sibling tools, which are all for specific Sophos operations, by being the 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?

Explicitly says 'Call this first to verify credentials are working,' indicating when to use it. While no alternatives or when-not-to are given, the context of being an authentication tool makes its usage clear.

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