Create Channel

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

No annotations are provided, so the description carries the full burden of disclosing behavior. It only says a channel is created, without mentioning authentication requirements beyond 'authenticated user', side effects, idempotency, permission needs, or what happens on duplicate titles. For a mutation tool, this is minimal behavioral disclosure.

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?

The description is a single, front-loaded sentence with no filler or redundant wording. It efficiently communicates the core purpose. However, it is so terse that it omits necessary context, though this is more a completeness issue than a conciseness issue.

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?

With no annotations, no output schema, four parameters, and zero schema description coverage, the description should provide substantial context. It provides only the basic action and owner. Missing details include required versus optional parameters, visibility semantics, group_id meaning, and any behavioral consequences of creating a channel.

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 0%, and the description does not mention any of the four parameters. It does not explain that title is required, what group_id refers to, what visibility values mean, or how description is used. The description adds no value beyond the raw schema field names.

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 states a specific verb and resource: 'Create a new channel for the authenticated user.' This clearly identifies the operation and is distinct from sibling tools like get_channel_contents and create_block. However, it does not clarify what a 'channel' is or how it differs from a 'block', leaving slight room for ambiguity.

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 gives no guidance on when to use this tool versus alternatives such as create_block or search_arena. There are no conditions, prerequisites, or exclusions provided. Usage must be inferred entirely from the tool name.

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