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

With no annotations, the description carries the burden of behavioral disclosure. It does explain the difference between placeholder env behavior (completes fixture) and live mode (returns authorize URL), which is valuable. However, it omits potential side effects, required credentials, or what the flow entails beyond the URL response.

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?

Two concise sentences convey the purpose, behavior, and mode distinction with no filler. The key information is front-loaded and every word earns its place.

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 simple tool with one parameter and no output schema, the description covers the essential behavioral modes. Minor gaps like required environment variables or how to use the returned URL are not critical for invocation, so the description is reasonably complete.

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 100%, so the parameter is already documented. The description adds context about fixture vs live mode but does not directly explain the 'fixture' parameter beyond implying its role. The schema already provides a clear description, so the baseline 3 is appropriate.

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 a specific action ('Connect OAuth') and the resource, distinguishing it from sibling tools that read/update payroll data. However, it does not explicitly compare itself to siblings, so it misses the full differentiation mark.

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 explains two modes (fixture sandbox vs live mode) with conditions implied by the environment, but it does not explicitly state when to use this tool over alternatives or provide any when-not-to-use guidance. Some context is given, but no exclusions or alternative routing.

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