clear_clip_envelope

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It states 'Clear' which implies destructive mutation, but it does not mention whether the action is undoable, what happens if no envelope exists, or whether it affects only the session clip (vs arrangement). The description lacks critical side-effect context for a destructive operation.

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 concise and front-loaded with the purpose in the first sentence, followed by a structured Args block. No unnecessary words are used, and every line adds 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?

The description covers the core functionality and all parameters, and an output schema exists so return values are not needed. However, it lacks context about clip type (session vs arrangement), prerequisites (e.g., device must exist), and potential side effects. For a 4-parameter tool with no annotations, the description is adequate but not fully complete.

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 provides only property names with no descriptions (0% coverage). The description compensates by explaining each parameter with the important 'Zero-based index' prefix and clarifies relationships: track_index points to a track, clip_index to a clip slot, device_index to a device on that track, and param_index to a parameter on that device. This adds sufficient meaning for correct invocation.

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: 'Clear the automation envelope for a specific device parameter in a clip.' This specifies the verb, resource, and scope, and differentiates it from siblings like clear_all_clip_envelopes and get_clip_envelope by focusing on a single parameter.

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 explicit guidance is given about when to use this tool versus alternatives such as clear_all_clip_envelopes or insert_clip_envelope_step. However, the description implies usage for clearing a single parameter's envelope, and the zero-based index parameters define the target precisely. This is implied rather than explicit.

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