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

No annotations exist, so the description carries full responsibility. It discloses that the tool produces a live session_id, that it uses the cookies from the pasted request, and that it 'sits' on the copied request's URL. It also reveals supported copy flavors and the absence of a password requirement. It does not mention side effects such as overwriting an existing session or any network implications, but the core behavior is thoroughly 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?

The description is four sentences, each adding distinct information: the interactive workflow, the output, and supported formats. It is front-loaded with the core purpose. There is no wasted wording, though the sequence of steps (DevTools → Network → right-click → Copy as cURL) could be condensed without losing meaning.

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 two-parameter tool with no output schema, the description provides enough operational context: where the input comes from, what the output is, and that the session inherits the URL. It lacks error scenarios or explicit limitations, but given the tool's simplicity, the description is otherwise 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 description coverage is 100%, so the baseline is 3. The description adds workflow context for the `curl` parameter (how the human obtains it and that it parses in three formats), which slightly enhances the schema. It offers no additional meaning for `use_proxy`, which the schema already describes clearly. Overall, the description adds some value but does not go far beyond the 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 states a specific verb and resource: 'Import login state from a real browser in one paste.' It explains the output (a live session_id with cookies, on the copied URL). This distinguishes it from sibling tools like session_create, session_cookies, or session_import by referencing the cURL paste workflow and 'no password or second login needed'.

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?

Clear usage context is provided: the human authenticates in their own Chrome first and then pastes a cURL command, avoiding re-login or CAPTCHA. The description explains exactly which precondition is required (single authentication) and that it works with bash, PowerShell, and cmd copy flavors. It does not explicitly name sibling alternatives to choose from, but the workflow guidance is unambiguous.

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