Reusable for this tool within 120 s of its time"Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly=false, openWorld=true, idempotent=false, and destructive=false, so the safety profile is clear. The description adds useful behavioral context about ownership and members, plus "Needs key," but does not explain side effects, permission needs, or what key does.
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 short and front-loaded, but it is under-specified for a five-parameter creation tool rather than appropriately sized. "Needs key" is terse to the point of ambiguity.
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 create operation with five parameters, zero schema descriptions, and no output schema, the description leaves major gaps: required name, proof, private, and the key requirement conflict are unaddressed. It provides only partial context about ownership and named members.
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% for all five parameters, so the description must compensate and largely does not. It vaguely references key and members but omits name (required), proof, and private, and "Needs key" misleadingly suggests key is required when the schema marks only name required.
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 identifies the resource and ownership model ("A channel for you and the members you name; you own it") but never states the creation action outright. With many sibling creation tools such as group_create, private_create, and space_create, it does not clarify how channel_create is distinct.
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?
It gives no explicit when-to-use guidance, prerequisites, or alternatives. It implies creating an owned channel but does not direct the agent away from channel_join, channel_invite, group_create, or other similar tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
