get_http_access

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

No annotations are provided, so the description must disclose behavior itself. It reveals the tool is a read-only GET call (queries GET /api/access), returns an HttpAccessInfo object, and explains the two fields (mode and key_valid) along with possible enum values. This is substantial transparency, though it omits details like error handling or authentication requirements.

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 well-structured and appropriately sized. The first sentence immediately states the purpose, followed by concise technical details and a use case. It avoids unnecessary fluff, though the implementation detail about the underlying SDK call adds a bit of length without affecting clarity.

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?

Given the tool's low complexity (no parameters, no output schema), the description fully explains what the tool does, what it returns (including field names and types), and when to use it. This is complete for an agent to correctly select and invoke the tool.

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 the baseline is 4. The description correctly makes no mention of parameters, since there are none to explain. The schema is empty, so the description does not need to compensate for any parameter ambiguity.

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's function: 'Retrieve HTTP access configuration from the Busy Bar device.' This specifically names the resource (HTTP access configuration) and the verb (retrieve), effectively distinguishing it from the many sibling get_* tools focused on other device aspects.

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?

The description provides a clear use case: 'Inspect HTTP access configuration before deploying tools that rely on the device's HTTP API to confirm the key setup is correct.' This gives contextual guidance on when to use the tool, though it does not name specific alternative tools or exclusions.

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