compute_login

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

Discloses that it opens a browser window and requires user interaction to complete login. No annotations are provided, so the description carries the full burden. It could mention that this is a non-blocking call, but the behavior is well explained.

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?

Concise, structured with sections for behavior, note, and returns. Every sentence adds value, no fluff. Front-loaded with key action and differentiation.

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 no parameters and existence of output schema, the description fully covers the tool's purpose, behavioral side effects, and return value. Complete for a simple login tool.

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?

Input schema has zero parameters, so description adds essential context about the login flow being browser-based and separate from CLI login. Schema coverage is 100%, and description enhances understanding.

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?

Clearly states the tool initiates Globus Compute OAuth login flow, distinguishing it from the Globus CLI login used for transfers. The verb 'initiate' and resource 'Globus Compute OAuth login flow' are specific, and the sibling tool 'globus_login' is explicitly differentiated.

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 states when to use (before submitting compute tasks) and when not to (for transfers, use Globus CLI login). Directly mentions the alternative 'globus_login' for transfers, providing clear guidance.

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