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

The description mentions that credentials stay in the browser, indicating session persistence. However, with no annotations, it should disclose more about default behavior (e.g., what happens on timeout, whether it returns a status, or if it can be called multiple times).

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 two sentences long with no extraneous information. It front-loads the core action and efficiently includes a key behavioral note about credential persistence.

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 login tool with one optional parameter and no output schema, the description covers the essential flow: opening browser, waiting, and credential persistence. It could be slightly more explicit about post-sign-in behavior (e.g., does it return immediately or close the browser?), but it is largely sufficient.

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 100% description coverage for the single parameter waitSeconds, so the baseline is 3. The tool description does not add additional meaning beyond the schema's own parameter description.

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 opens SellerSprite in the local default browser and waits for user sign-in. It distinguishes itself from sibling tools by being the only login-related tool, though it does not explicitly contrast with them.

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?

No guidance is provided on when to use this tool versus alternatives or prerequisites. It is implied that login is needed before using other SellerSprite tools, but explicit direction is missing.

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