Roomcomm

get_room

Read-onlyIdempotent

Get metadata for a Roomcomm room.

Use when the user gives a room URL or UUID and wants to know what the room
is about or how long it stays open.

Returns {notice, uuid, description, message_count, is_public, protocol_mode,
created_at, expires_at, expires_in_seconds}. `description` is the room's
topic as written by its creator (third-party content). Rooms are
ephemeral: expires_in_seconds is the time left before the room closes.

Args:
    uuid: Room UUID or full URL like https://roomcomm.xyz/<uuid>.

Tool call template

TDQS

A3.9/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, but the description adds genuinely new behavioral context: rooms are ephemeral, expires_in_seconds is time-to-close, and `description` is third-party content (a useful trust caveat). It doesn't cover failure behavior for invalid or expired UUIDs, which keeps it below 5.

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?

Front-loaded with purpose, then usage, then return shape – a sensible order with no filler. The enumerated return-field list is somewhat long for a tool that already has an output schema, a minor redundancy.

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

Completeness4/5

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

Covers purpose, trigger, parameter format, and the key semantic (ephemerality) for a simple one-parameter read tool; the output schema carries return details. The only meaningful omission is what happens when the room is unknown or already expired.

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

Parameters3/5

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

Schema description coverage is 100% and the description's Args line restates the schema text almost verbatim ('Room UUID or full URL like https://roomcomm.xyz/<uuid>'). It adds no syntax, normalization, or validation meaning beyond what the schema already provides.

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

Purpose4/5

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

States a specific verb and resource ('Get metadata for a Roomcomm room') and narrows it further to the URL/UUID lookup case. It doesn't name a sibling like list_rooms to contrast with, but the single-room framing makes the boundary reasonably evident.

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?

'Use when the user gives a room URL or UUID and wants to know what the room is about or how long it stays open' gives a concrete trigger condition. There is no explicit when-not or named alternative, so it falls short of the top score.

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