Approve membership request

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

Adds genuine behavioral context beyond the annotations: an AutoDM is triggered to the applicant as a side effect and the caller must be an admin/moderator. However it never addresses irreversibility (annotations flag destructiveHint=true), failure modes for an already-approved or stale request, or rate/bulk behavior.

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 sentence 'your AutoDM, if set, goes out as usual' appears twice nearly verbatim, and the opening 'Let an applicant into the group' is restated immediately after. Real information is buried in a duplicated, out-of-order block rather than front-loaded.

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 two-parameter mutation whose schema and annotations are fully populated, the description covers the essentials an agent needs: single-request scope, admin/mod requirement, and the AutoDM side effect. Missing only failure/reversibility notes, which is a modest gap given destructiveHint already signals risk.

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 coverage is 100%, so both parameters are already documented, including that request_id comes from list_membership_requests. The description's only addition is the member_id/request_id equivalence note, which is mildly useful but introduces a parameter name that does not exist in the schema.

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: 'Approves one pending request, so the applicant becomes a member,' anchored to a known UI action ('as Skool's Approve button does'). The scope is limited to a single request, which implicitly separates it from bulk/list operations, but the natural counterpart decline_membership_request is never named.

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?

Gives a real prerequisite ('Admins and moderators only') and makes clear it acts on one pending request per call, which tells the agent it must loop for multiple requests. It does not route the agent between approving vs declining or removing a member, so no explicit exclusions are stated.

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