action1_navigate

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

No annotations are provided. The description implies read-only behavior ('discover'), but does not explicitly state whether it modifies state or the format of the response. Some behavioral traits are clear, but not fully disclosed.

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 sentences, front-loaded with the main purpose, and contains no unnecessary 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 discovery tool with one parameter and no output schema, the description is adequate but could specify what the tool returns (e.g., list of tool names). The context signals indicate low complexity, so this is acceptable.

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 input schema has 100% description coverage with enum values explained. The description adds 'by domain' context, but adds little beyond the schema's parameter descriptions.

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 purpose as 'Discover available Action1 tools by domain,' distinguishing it from sibling tools that retrieve actual data. However, the name 'navigate' could be misleading without the description.

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 explicitly says 'All tools are callable at any time — this is a help/discovery aid,' which informs when to use it. It doesn't specify when not to use it, but as a discovery tool, alternative guidance is not necessary.

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