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

Annotations already indicate idempotent and non-destructive, and the description adds context about behavioral traits: it can establish a permanent connection via config header (non-expiring) or a session-only login via pasted token, plus the no-args behavior returns a link. This complements the annotations without contradiction.

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, somewhat dense paragraph but each clause provides critical information: target audience, login flow, two token-handling options, and the no-arg call. It could be split into bullet points, but the current structure is efficient and front-loaded.

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 has one optional parameter and no output schema, the description covers all necessary details: how to authenticate, where to place the token, session vs. permanent options, and the no-arg link retrieval. It is fully sufficient for an agent to use correctly.

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 schema has a single 'token' string with no description and 0% coverage, but the description explains that 'token' is a JWT pasted after user authentication, and explicitly notes that calling with no args yields the link. This adds essential meaning beyond the bare schema.

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 the tool authenticates the user for IDE agents (e.g., Cursor), with specific actions: log in via browser, copy access token, and either set a header in config or provide a token for session. This is a specific verb+resource with scope and differentiates from sibling tools like 'connect' or 'marketplace'.

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?

It explicitly explains when to use the tool (for IDE agents), provides two usage modes (permanent config header vs. session-only token), and instructs to call with no args to get a link. It doesn't explicitly state exclusions or alternatives, but the guidance is clear enough for an agent to decide when to invoke it.

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