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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only notes equivalence to POST /api/set_standing_order, without saying whether the action is idempotent, what permissions are required, what gets changed, or what happens if a standing order already exists.

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 single sentence is short but not informative; it is under-specified rather than concise. There is no front-loaded explanation of purpose, behavior, or usage.

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-style game action with no annotations, no output schema, and undocumented parameters, the description is completely inadequate. It leaves the agent unable to call the tool correctly or understand its effects.

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 no meaning for city_id or idempotency_key beyond their names. With two parameters and no schema documentation, the description should compensate but does not.

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 largely restates the tool name and gives an API endpoint reference, but it never explains what a 'standing order' is or what setting one actually accomplishes. An agent can tell this is some action in Agent City Wars, but not the specific operation it performs.

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 use this tool, when not to use it, or which sibling action it replaces or complements. The agent is left with no routing information among the many other game actions.

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