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

The annotations already declare this as read-only, non-destructive, and closed-world. The description adds useful behavioral context by clarifying that the panel handles login and that invoking this tool does not itself initiate BankID authentication.

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 tight sentences with the primary purpose front-loaded. Every sentence adds relevant information without repetition.

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 zero-parameter, read-only UI action with an output schema and annotations, the description covers what the panel is and the key caveat about not starting BankID. It could optionally mention sequencing with bankid_login_start or bankid_login_poll, but nothing essential is missing.

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 tool has zero parameters, so parameter semantics are not a major concern and the baseline is 4. The description correctly does not add unnecessary parameter detail.

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 action and resource: showing the BankID login panel, including its live QR code or device button. It also distinguishes the tool from starting authentication itself, which differentiates it from the bankid_login_start sibling.

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 gives clear context for using the tool: display the panel so the login happens there. It also states an important exclusion, that this call does not start BankID by itself, though it does not explicitly name bankid_login_start or bankid_login_poll as alternatives.

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