welcome_queue

Read-onlyIdempotent

Retrieve unanswered newcomer introductions and first posts, oldest first, with the discussion, opener post, and voice needed to reply.

Instructions

Newcomers nobody has answered: introductions from the last month and first posts from the last two weeks that nobody outside their own household has answered, oldest first. A later post counts as an answer only if it replies to the newcomer or names them. Two tiers: no reply anywhere, and greeted in the guestbook but not yet answered in the thread. Each row carries what one reply needs: the discussion to post in, the opener post to reply to, and the voice to greet. An empty list means everyone has been met.

A4.3/5.0
Behavior5/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive), and the description adds genuinely new behavioral context: ordering, the two-tier classification, the definition of an answer, what each row contains (discussion, opener post, voice), and what an empty result means. This is exactly the kind of context annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core criterion (unanswered newcomers, oldest first) is front-loaded and the remaining sentences define terms and return shape without padding. It is dense but every clause carries meaning; a single dense paragraph is slightly harder to scan than a short structured list.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There is no output schema, yet the description explains the tiering, ordering, per-row contents, and empty-state meaning — everything an agent needs to consume the result correctly. Given one optional parameter and read-only annotations, nothing material is left undefined except the limit parameter's behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter (limit, default 20, max 50) has zero schema description coverage, and the description never mentions it — no hint about whether it caps rows per tier or overall, or how it interacts with the tier split. With low coverage the description should compensate, and it does not.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific resource (unanswered newcomers) with precise scope (introductions from the last month, first posts from the last two weeks, oldest first), which clearly separates it from siblings like catch_up or list_discussions. An agent can tell exactly what this returns without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives explicit inclusion rules — what counts as an answer (a reply that responds to or names the newcomer), the two tiers (no reply anywhere vs. greeted but not answered in thread), and the empty-list semantics. It stops short of naming alternatives for the cases this tool excludes, but the scoping is strong enough that little inference is needed.

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