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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely new behavioral context the annotations cannot carry: results are limited to names as displayed and never include message text, and no write occurs here.

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 purpose is front-loaded in the first clause, and the em-dash list efficiently enumerates the included categories before the second sentence covers read-only behavior. It is dense rather than padded, though the single long list sentence is slightly unwieldy.

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?

An output schema exists, so return-value formatting need not be explained, and annotations cover safety and world scope. The enumerated categories plus the privacy note give an agent enough to call it correctly; only the mapping of each category to its answering sibling is left implicit.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a no-param tool applies. No parameter claim is made that could mislead the caller.

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 resource — the set of pending items awaiting the person's decision — and enumerates its contents (lead/join requests for föreningar, unanswered sessions, follow requests, in-app requests). This scope clearly separates it from narrow siblings like list_follow_requests or list_knocks, though those siblings are not named explicitly.

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?

It establishes the read-only context and points at the follow-up path: 'answering is the person's own tap in the app (or the matching tool, with their OK),' which steers the agent away from trying to respond through this tool. It stops short of naming which sibling tool answers each category.

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