x_extract_community

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

No annotations are supplied, so the description carries the full behavioral burden. It says the tool 'opens' the community but does not disclose whether this requires the browser to be on a logged-in session, whether it navigates the page as a side effect, whether it waits for load, or what happens on a private/restricted community where metadata is not visible.

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?

A single front-loaded sentence with no filler. Slightly low on information density but structurally clean.

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 single-URL extraction tool with no annotations and no output schema, the description covers the high-level return shape but omits authentication prerequisites, navigation side effects, and error behavior. It is minimally adequate but leaves real gaps given the lack of structured disclosure elsewhere.

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 100% and there is only one parameter, whose meaning ('Full X community URL') is fully specified in the schema. The description adds no parameter-level detail, so baseline 3 applies.

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 ('Open') and resource ('community') and enumerates the returned metadata (name, description, member/post hints, join state). It does not differentiate from sibling x_open_community, which likely navigates to the community rather than extracting structured metadata — the description would be stronger if it named that distinction.

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 and no mention of alternatives. The sibling set contains x_open_community, x_search_communities, and x_map_community, all plausible confusions, yet the description offers no routing criteria.

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