huddle

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

With no annotations, the description carries the full behavioral burden. It does disclose real traits: close is permission-gated ('whoever started it, or the team owner'), design requires a proposal that becomes idea #1, and react requires a reason. It says nothing about mutability of the read actions, whether closed huddles are immutable, notification effects on teammates, or error behavior when the huddle is not open.

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?

One dense paragraph with zero filler sentences; each clause maps to a distinct action. The opening tagline 'Think together like a real dev team' is atmosphere rather than information, and the action list would read better as separate lines, but the sizing is appropriate for a 7-action, 13-parameter tool.

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 multi-action tool with 13 parameters, no annotations, and no output schema, the description covers every action and several key constraints (permissions on close, required proposal for design). It still leaves return shapes for list/get unexplained and gives no guidance on state requirements, which an agent needs before calling idea/comment/react.

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?

Schema description coverage is 100% and every parameter description already carries its action prefix, so the schema does the heavy lifting. The description adds marginal value by narrating how parameters combine per action (design proposal becomes idea #1, react needs vote plus reason), but it repeats rather than extends the schema. Baseline 3 applies.

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 names a concrete resource (huddle) and enumerates all seven actions with a specific verb and object for each (start/list/get/idea/comment/react/close), so an agent can tell what the tool does. It stops short of differentiating itself from siblings like team_post or team_ask, which also appear to handle team communication.

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?

Each action carries an implied usage condition (review = ask teammates to look at a branch/commit/task; standup = everyone posts done/next/blockers; close = record the decision), and 'optionally only with some people' scopes start. However there is no explicit guidance on when to open a huddle versus posting via team_post/team_ask, nor any stated prerequisites such as needing an open huddle for idea/comment/react.

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