create_live_transcode_rule

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

No annotations are provided, so the description carries full burden. It states '创建' (create) which implies a write/mutation operation, but doesn't disclose behavioral traits like whether this requires specific permissions, if it's idempotent, what happens on failure, or if there are rate limits. The description only lists parameters and a return value without explaining the tool's behavior beyond the basic action.

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 appropriately sized and structured with clear sections for Args and Returns. It uses minimal text to convey the basic information, though the parameter section is redundant with the schema. No unnecessary elaboration or wasted sentences.

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 mutation tool with no annotations and no output schema, the description is incomplete. It doesn't explain what a 'live transcode rule' is, how it integrates with the system, what the '请求ID' (request ID) represents, or error conditions. Given the complexity of live streaming operations and lack of structured context, more explanation is needed.

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 100%, so the schema already documents all parameters thoroughly. The description merely repeats the parameter names in Chinese without adding any additional meaning, examples, or context beyond what's in the schema. This meets the baseline for high schema coverage but doesn't provide extra value.

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 '创建转码规则' (create transcode rule), which provides a basic verb+resource combination. However, it doesn't specify what type of transcode rule (e.g., live streaming, real-time encoding) or how it differs from sibling tools like 'create_live_transcode_template' or 'delete_live_transcode_rule'. The purpose is clear but lacks sibling differentiation.

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 is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites, when this tool is appropriate, or what happens after creation. For example, it doesn't clarify if this should be used before or after creating a transcode template, or how it relates to other live streaming operations.

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