list_scenarios

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds that it lists 'every published situation' (a scope detail) and the returned fields. However, it does not discuss pagination, ordering, or potential edge cases (e.g., empty list). The behavioral disclosure is adequate but minimal beyond annotations.

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 of 12 words, front-loaded with the verb 'List'. It conveys essential information (what is listed, what fields) without any extraneous content. 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?

Given the tool's simplicity (0 parameters, an output schema exists), the description is nearly complete. It states the scope ('every published situation') and the fields included. Minor missing context includes ordering, default listing behavior, and what happens if no situations exist, but the presence of an output schema likely covers the return structure.

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 0 parameters, so there is nothing to document. The description does not need to add parameter semantics. The baseline for 0 parameters is 4, and the description meets this without requiring further elaboration.

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 action ('List') and the resource ('every published situation'), and specifies the output fields (title, category, slug, canonical URLs). This distinguishes it from siblings route_emergency (routing) and get_scenario (single scenario retrieval).

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 provides no guidance on when to use this tool versus alternatives like get_scenario. It does not mention exclusions, prerequisites, or typical use cases. With sibling tools present, such context would be valuable.

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