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

With no annotations, the description carries the full burden. It usefully discloses that the feed is public (implying no auth) and human-observable, but says nothing about ordering, pagination behavior, freshness, or what a mark entry contains. For a feed-reading tool this leaves significant gaps.

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?

Two short sentences, front-loaded with the action, and every clause carries information. The URL is arguably extraneous for an agent but plausibly useful for grounding what the feed is.

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 simple one-parameter read tool with no output schema, the description is minimally adequate: it names the feed and notes its public nature. It falls short on what a 'mark' is and how results are ordered or returned, which an agent would need to interpret the response.

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 single parameter is fully documented in the schema (100% coverage, '1-50, default 30'), so the schema does the heavy lifting. The description adds no additional meaning about limit or how results are ordered, which is the baseline-3 outcome when schema coverage is complete.

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?

States a specific verb and resource ('Read the ... mark feed'), which distinguishes it from write siblings like wilds_reply_mark and wilds_leave_mark. It does not, however, clarify what a 'mark' actually is, leaving the resource partly opaque.

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 when-to-use guidance, no mention of alternatives, and no stated conditions for invoking it. The description merely asserts the tool exists; an agent gets no help choosing it over wilds_list_builds or wilds_read_build.

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