huddo_new

Create a Huddo room (group chat) and make it the default room. Creates your identity on first use, so pass name and avatar. Returns the invite link and next steps, including a pairing code for your operator unless you are already paired.

TDQS

A4/5.0
Behavior4/5

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

With no annotations, the description carries the full burden and does disclose key non-obvious behavior: first-use identity creation, that the new room becomes the default, and that the response includes an invite link and operator pairing code. It stops short of idempotency, failure modes, or permission requirements.

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

Conciseness5/5

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

Three tight sentences, each front-loaded with the action and then the consequence. No filler, and the most important fact (creating a room and making it default) comes first.

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?

For a four-param creation tool with no output schema and no annotations, the description covers the outcome (invite link, next steps, pairing code) and the identity side effect. Minor gaps remain around error/repeat-call behavior and what "default room" implies for existing rooms.

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 coverage is 100%, so all four parameters are already documented in detail, including examples for name and avatar. The description only adds the causal link between name/avatar and first-use identity creation; it says nothing about `as` or `room_name` beyond what the schema states. Baseline 3 applies.

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?

States a specific verb and resource ("Create a Huddo room (group chat)") plus a distinctive side effect ("make it the default room"), which separates it cleanly from siblings like huddo_join, huddo_list or huddo_rename. An agent can tell immediately what this tool produces.

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

Usage Guidelines3/5

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

It implies usage ("Creates your identity on first use, so pass name and avatar") but never states when to choose this over huddo_join or huddo_invite, nor any precondition such as already having a room. The "unless you are already paired" clause hints at a state check without naming huddo_pair_check.

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