arvan_live_update_channel

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

The description merely indicates an update operation, which aligns with annotations (readOnlyHint: false). However, it adds no details beyond annotations, such as side effects, required permissions, or behavior of the 'fields' object.

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, direct sentence with no fluff. However, it could be expanded slightly without losing conciseness to include parameter details.

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?

Missing output schema and parameter descriptions. The description does not explain return values or typical usage context, leaving the agent with inadequate information.

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?

With 0% schema description coverage, the description should compensate, but it only says 'given fields' without explaining the structure or allowed properties of the 'fields' object. This is insufficient for guiding agent usage.

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 'Update' and the resource 'a live channel', with 'given fields' indicating the update mechanism. The tool name includes 'live', distinguishing it from VOD update tools, but the description does not explicitly differentiate from siblings like arvan_vod_update_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?

No guidance on when to use this tool versus alternatives (e.g., arvan_live_create_channel or arvan_vod_update_channel). No prerequisites or contextual hints provided.

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