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

No annotations are provided, so the description carries the full burden, and it discloses nothing: not whether this is a read, not scope of returned events, not pagination, not whether the idempotency_key matters for a get operation. The endpoint reference is not a behavioral trait an agent can act on.

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?

It is short, but short by omission rather than by discipline. The single sentence is under-specified and spends its words on an API route reference rather than on the information an agent needs.

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 tool in a complex multi-action game API, with zero parameter documentation, no annotations, and no output schema, the description is wholly inadequate. Nothing tells the agent what it will receive or how to interpret it, and no structured field compensates.

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 0%, and the description adds nothing about either parameter. An agent must guess whether city_id scopes events to one city, whether it is required to be a city it controls, and what idempotency_key means for a 'get'-style action.

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 text restates the tool name ('get_world_events') and adds an endpoint equivalence ('identical to POST /api/get_world_events') that conveys nothing about what the tool actually returns. It does not say what a 'world event' is, nor distinguish it from siblings like get_turn_packet, get_map, or get_battle_report, which are the obvious alternatives an agent would weigh.

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?

There is no indication of when to call this tool, when not to, or which sibling to prefer for world/state information. The agent is given no routing criteria at all.

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