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

No annotations are provided, so the description carries the full burden. It reveals only that this is a game action equivalent to a POST endpoint, implying a mutation, but says nothing about resource costs, prerequisites, irreversibility, or failure modes — essential for a state-changing game action.

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 because it is under-specified rather than efficient. The parenthetical endpoint mapping is low-value for an agent choosing a tool, while the information that actually matters is absent.

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 mutation tool with no annotations, no output schema, and 0% parameter documentation, the description leaves nearly every operational question unanswered — preconditions, cost, result, and sibling differentiation. It is not adequate for correct invocation.

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% for the single 'name' parameter, and the description adds no clarification. An agent must guess whether 'name' is the city name, a player name, or something else, and whether it is required (it is not listed as required).

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 name and the phrase 'Agent City Wars action found_city' imply founding a city in a game, and the parenthetical maps it to POST /api/found_city. But the description never states the effect (creating a new city), what it costs, or how it differs from the sibling 'found_second_city', which is a critical distinction left to inference.

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 guidance on when to call this versus alternatives. Given siblings like found_second_city and get_city, the description should say when founding is valid (e.g., first city only) and point elsewhere for subsequent cities, but it does none of that.

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