navigate

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

No annotations are provided, so the description bears full responsibility. It mentions 'stealth browser' and 'discover session-specific actions', which hint at behaviors but lack detail on side effects, permissions, or state changes. This is insufficient for a mutation tool.

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?

Single sentence with front-loaded verb 'Navigate'. No wasted words, but the secondary action ('discover session-specific actions') could be separated for clarity. Still highly concise.

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 one-parameter tool with no output schema, the description covers the primary action but omits what the agent receives back (return value). It mentions 'discover actions' but doesn't specify the response format. Adequate but incomplete.

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 coverage is 100% (one parameter 'target'). The description simply repeats the schema's 'URL to navigate to' without adding new constraints or format details. With full coverage, baseline 3 is appropriate.

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 navigates to a URL and discovers page actions. It uses a specific verb ('navigate') and resource ('stealth browser'), distinguishing it from sibling tools like hydra_execute or hydra_probe.

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 implies usage for navigation tasks but provides no explicit guidance on when to use vs alternatives, no prerequisites, and no when-not-to-use information. The intent is clear from the name but undeveloped.

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