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

The description thoroughly discloses behavioral traits: replacement semantics, inheritance chain, normalization and validation failures, refusal conditions, side effects (public history), and the ownerless world restriction. This goes well beyond the annotations (readOnly=false, destructive=true) and provides substantial operational detail. No contradiction with 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 lengthy and includes tangential guidance about Room #454 and general navigation, which dilutes the core message. However, the main action is stated up front, and the complex inheritance rules are explained in an ordered manner. It is not as concise as it could be.

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 with two underdocumented parameters and no output schema, the description provides exhaustive context: ownership requirement, inheritance chain, trait validation, conversion rules, and side effects. It also includes a specific workflow for a related room. The only missing piece is an explicit description of the return value, but given no output schema, that is a minor gap.

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 description provides rich semantics for both parameters: place_id must be a place the user owns, and traits are ordered law traits with normalization rules, existence requirements, and allowed/forbidden attributes. Since schema coverage is 0%, the description fully compensates and even goes beyond.

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 (replace), the resource (ordered law traits for a place you own), and provides distinguishing context about inheritance and scope. It is specific and not a tautology, and it separates itself from sibling editing tools by focusing on laws.

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 some usage conditions (e.g., ownerless world accepts no laws, traits must already exist) and a procedural note about Room #454, but it does not explicitly contrast with sibling tools or state when to choose this over alternatives. The context is clear but exclusions are absent.

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