hydra_execute

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

With no annotations provided, the description carries full burden for behavioral disclosure. It only mentions 'autonomous execution' and 'complete the task', but omits critical details like whether the tool is read-only, side effects, failure behavior, or any state mutations. This is insufficient for an agent to infer safe usage.

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 sentence, highly concise with no fluff. However, it sacrifices necessary detail for brevity. It earns a 4 because every word serves a purpose, but could be expanded without losing conciseness.

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 2 parameters and no output schema, the description is minimally viable. It covers the basic what and how, but lacks information on return values, error handling, or limitations. It meets the minimum threshold for an agent to attempt usage.

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?

Schema description coverage is 100%, so baseline is 3. The description adds minimal semantic value beyond the schema—it restates 'target URL' and 'goal' without explaining how these are used or expected formats. No additional constraints or examples are provided.

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 does 'one-shot autonomous execution' with a target URL and goal, distinguishing it from sibling tools like 'navigate' (just navigation) and 'hydra_probe' (probing). The verb 'execute' combined with 'automatically' and the required params make the purpose unambiguous.

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 on when to use this tool versus alternatives (e.g., hydra_probe for exploration, navigate for simple navigation). The description lacks any 'when to use' or 'when not to use' context, leaving the agent to infer usage from the name alone.

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