sequence.set_volume

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

With all annotations false, the description must carry the burden of disclosing behavior. It only mentions 'Risk: standard; maturity: L3' and 'Per-request argument checks and session policy still apply', which are generic and not specific to this operation. No side effects, mutation characteristics, or response details are disclosed.

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 extremely short, but this is under-specification rather than effective conciseness. It lacks any front-loaded purpose statement and consists only of metadata that does not help an agent. It does not earn its place because it provides no operational value.

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 six parameters (three required) and an output schema, the description is completely inadequate. It fails to explain the tool's function, parameter usage, or expected results. An agent cannot determine how to invoke this tool correctly based on this definition.

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 coverage is only 50%, and the only described parameters are generic harness fields (_requestId, _authorization, _transactionId). The core functional parameters 'name' and 'volume' have no schema descriptions, and the tool description adds zero clarification about their meaning or constraints. The description does not compensate for the missing schema coverage.

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 merely restates the command name 'sequence.set_volume' and adds risk/maturity metadata. It gives no verb or resource indicating what the tool actually does (e.g., setting the volume of a sequence). This is a tautology, similar to the 'Process' example.

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 like blender_sequence_keyframe_volume or blender_sequence_set_speed. There is no mention of use cases, prerequisites, or exclusions, leaving the agent without any routing information.

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