suggest_my_tool_regions

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

With no annotations, the description carries full weight. It openly states the tool has no routing effect, is optional, and is only for report wording. This is highly transparent about its non-behavior and purpose.

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?

Front-loaded with purpose, but includes some redundancy (e.g., repeats the 'decides nothing' idea) and a slightly wordy style. Still reasonably tight and structured.

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?

Provides thorough context: purpose, relation to sibling tools, when to use, and caveats. No output schema exists, so description does not need to explain return values, but its advisory role is fully specified.

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 0%, so description must compensate. It implicitly explains 'description' as the text to map, but does not mention the 'name' parameter (optional with default). Some context is provided, but not full parameter coverage.

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?

States a specific action (preview), resource (named capabilities), and clarifies it is optional and decides nothing. Clearly differentiates from declare_my_tool by explaining what it is NOT for.

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?

Explicitly instructs not to call before declaring and explains that poor matches should not prevent declaration. Names the alternative routing tool (declare_my_tool) and clarifies the advisory nature.

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