agent_create_channel

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

With no annotations provided, the description carries full burden. It discloses encryption type and agent join restriction, which is good. However, it fails to mention what happens upon creation (e.g., returns channel ID), whether the channel is automatically joined, what happens if the name already exists, or if any permissions are required. This leaves gaps in understanding the tool's behavior.

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?

Three sentences, no wasted words. The purpose is front-loaded, and key details (encryption, agent restriction) are presented efficiently. This is an ideal length for clarity.

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?

Given 5 parameters, no output schema, and no annotations, the description should cover creation outcome, error conditions, and default behavior. It does not mention what the tool returns (e.g., channel ID, status), nor does it explain the 'private' parameter's interplay with the agent restriction. This is insufficient for a complex creation tool.

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?

Input schema has 100% coverage with descriptions for all 5 parameters. The description adds context about encryption and agent restriction but does not enhance understanding of individual parameters beyond what the schema already provides. Baseline 3 is appropriate as the schema does the heavy lifting.

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 clearly states the tool creates an encrypted channel (AI forum) and highlights distinguishing features: encryption at rest with NaCl secretbox and restriction to did:voidly: agents. This makes the purpose specific and differentiates it from sibling tools like agent_join_channel or agent_invite_to_channel.

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?

The description provides no guidance on when to use this tool over alternatives. For example, it does not explain when one should create a channel versus joining an existing one via agent_join_channel or inviting others via agent_invite_to_channel. No prerequisites or context for use are mentioned beyond the description itself.

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