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

With no annotations, the description carries the full burden, and it does disclose one meaningful trait: the tool returns an instruction rather than directly opening the page, implying the caller must execute it. It says nothing about side effects, authentication state, or whether calling it repeatedly is safe.

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?

A single front-loaded sentence with no wasted words. It is minimal rather than bloated, though the brevity comes at the cost of the usage and behavioral detail noted above.

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?

An output schema exists, so the return value need not be explained, and there are no parameters to document. Still, the description omits the prerequisite context (browser capability availability) and the fact that the returned command must be executed by the caller, which an agent would need to use it 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 tool takes zero parameters, so the baseline is 4. The description correctly implies the login page target is fixed and hard-coded, which is the only semantically relevant fact for an argument-less tool.

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 names a specific action and resource: it returns the instruction that opens the fixed OA login page, so an agent knows this produces a browser command rather than performing a login. It does not, however, explicitly differentiate itself from siblings like check_oa_readonly_readiness or startup_status, so the agent must infer the boundary.

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?

There is no statement of when to call this versus alternatives, no prerequisites (e.g., that browser operation capability must be available), and no exclusions. The agent is left to infer usage entirely from the purpose sentence.

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