oc_open_host_settings

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

The description reveals that the tool opens a browser page, which is useful behavioral information. However, it does not detail side effects such as whether a new tab is created, focus changes, or if the call fails silently when no browser is present. Annotations do not provide additional safety context, so the description carries some burden but falls short of full transparency.

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, clear sentence that immediately conveys the tool's purpose. It is front-loaded, concise, and contains no superfluous words.

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 simple tool with one parameter and no output schema, the description is fairly complete. It explains what the tool does and what input it takes. However, it could mention that it opens in the default browser and implicitly requires a browser environment, which might affect completeness for agents lacking that context.

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 description does not add meaningful information about the 'host' parameter beyond what the input schema already provides (enum values and a short description). With 100% schema coverage, a baseline of 3 is appropriate since the schema already documents the parameter adequately.

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 the MCP connector settings page for a web AI host in the default browser. It uses a specific verb and resource, and it is distinct from siblings like 'oc_devtools_url' or 'cookies' which deal with different settings or configuration.

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. There is no mention of prerequisites (e.g., whether the host must be configured first) or context in which this tool is appropriate, leaving the agent to infer usage.

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