create_brain

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It only states the action is to queue or resume indexing, without revealing side effects, permissions, idempotency, or potential impact on existing data. This is insufficient for a mutation-like tool.

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 concise sentence with no redundant words. It front-loads the action clearly and is appropriately sized for the information it conveys.

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 the tool has three parameters and no annotations, the description is too sparse. It omits parameter semantics, call behavior (e.g., what happens on repeated calls), and prerequisites. Although an output schema exists, the description still leaves significant gaps for a mutation 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?

The schema description coverage is 0%, and the description does not mention any of the three parameters (channel_url, language, max_videos). The description adds no clarity about how these parameters influence the indexing behavior, leaving the agent without guidance.

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 action ('Explicitly queue or resume') and the resource ('local channel caption indexing'), which is specific and distinguishes it from sibling tools that handle status, listing, search, transcript, and deletion. The name 'create_brain' is ambiguous, but the description resolves it by explaining the actual behavior.

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 phrase 'Explicitly queue or resume' implies this tool is for manually triggering indexing, but it does not state when to use it versus alternatives, nor does it mention prerequisites or exclusions. There is no explicit guidance on when to prefer this over sibling tools like get_brain_status.

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