Check Azure DevOps authentication

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

With no annotations, the description carries the full behavioral burden. It adds an important safety guarantee ('without exposing credentials') and implies a read-only check, but it does not disclose what happens on success or failure, whether the call is non-mutating, or what the returned status looks like.

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 a single, front-loaded sentence with no filler. It states the core action first, adds the optional scope, and closes with a relevant safety qualifier. Every word contributes.

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 such a simple, one-parameter tool this is mostly adequate, but the lack of an output schema and annotations means there is no explanation of the return value or typical failure modes. An agent can invoke it safely given the schema, but would be guessing at how to interpret the result.

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 description coverage is 100% for the only parameter, so the schema fully documents 'project' including the default-project fallback. The tool description's phrase 'optional project access' weakly reinforces the parameter's meaning but adds no new semantic detail.

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 uses a specific verb 'Verify' and clearly names the resource being checked: authentication plus optional project access. This distinguishes it sharply from the sibling tools, none of which are authentication checks.

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 usage is implied by the verb 'Verify' – an agent can infer this should be used to validate Azure DevOps credentials before other API calls. However, it does not explicitly state when to use it versus alternatives or mention any prerequisites.

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