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

With no annotations, the description carries the full behavioral burden, and it largely fails to. 'Bounded, provenance-labeled rules' is unexplained jargon that does not disclose what mutations occur, what idempotency or signature requirements mean, or any rate/size limits.

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 a single front-loaded sentence with no padding, which is good. But the trailing 'using the same bounded, provenance-labeled rules' phrase adds no actionable information, so brevity comes at the cost of substance.

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 high-complexity tool with 9 params, a nested object, no annotations, no output schema, and 0% schema coverage, this one-sentence description is grossly insufficient. An agent has almost nothing to safely construct a correct call.

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% across 9 parameters (6 required), including non-obvious fields like idempotencyKey, publicKeyJwk, signature, and inReplyTo. The description explains none of them, so an agent must guess at their formats and roles.

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 states a specific verb and resource: 'Reply to a visible Wild Plaza mark.' This distinguishes it from siblings like wilds_list_marks or wilds_vote at a coarse level. However, it does not differentiate from the closest sibling wilds_leave_mark, and the trailing clause is vague rather than clarifying.

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 only usage condition is the word 'visible,' implying the target mark must already exist and be visible. There is no guidance on when to reply versus leave a mark, vote, or chronicle, nor any mention of prerequisites or alternatives among the sibling tools.

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