update_invites_requests_by_invite_id

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

Annotations already convey mutation, idempotency, and non-destructiveness. The description adds the 'PUT' method and the accept semantics, but does not disclose downstream effects such as creating friend relationships or granting Plex Home/server access after acceptance.

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 short and front-loaded with the essential action. The endpoint and argument list are directly useful, though the endpoint line slightly duplicates information inherent in the tool name.

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 four-parameter mutation with an output schema, the description covers the action, endpoint, and every parameter's meaning. It does not provide broader context such as invite lifecycle or error cases, but none are essential to invoke it correctly.

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?

With 0% schema description coverage, the description fully compensates by defining invite_id as the pending invitation ID and clarifying friend, home, and server as relationship-bearing flags. The 'Whether' phrasing suggests booleans while the schema types are string/null, so a small ambiguity remains.

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 opens with a specific action verb and resource: 'Accept an Invite,' and identifies the endpoint. It clearly distinguishes the tool's purpose from generic library/playlist updaters in the sibling list, though it does not name an alternative.

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 implies when to use the tool: when accepting a pending invite. However, it provides no explicit guidance on prerequisites, what constitutes a pending invitation, or when a different invite-management tool would be more appropriate.

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