http_get

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

With no annotations, the description carries the burden for behavioral disclosure. It correctly states the core behavior (an HTTP GET) and the allow_http restriction, but it does not mention error handling, timeouts, redirects, or response behavior. The disclosure is adequate but thin.

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 short sentences with zero filler. It front-loads the action and adds a critical availability constraint, so every word earns its place.

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?

The tool is simple, and an output schema likely documents return values, lowering the burden on the description. Still, the description doesn't cover expected behavior on non-200 responses, error cases, or practical usage context. It is minimally adequate.

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 schema has one parameter, url, with 0% description coverage. The description's phrase 'HTTP GET a URL' confirms that the parameter is the target URL, adding some meaning beyond the schema's bare 'Url' title. However, it does not specify URL format, supported schemes, or other constraints.

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 operation with a specific verb and resource: 'HTTP GET a URL.' This is enough to understand what the tool does and is implicitly distinct from siblings like json_get or read_file, though it lacks an explicit differentiation.

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 gives no guidance on when to use this tool versus alternatives such as json_get or read_file. The only usage-related note, 'Disabled unless allow_http is enabled,' is a configuration prerequisite rather than a selection guideline.

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