set_clip_enabled

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the tool verifies the updated state and that disabling equates to muting, but it omits permission/auth requirements, error behavior when a clip cannot be resolved, and what the verification returns.

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?

A single front-loaded sentence that names the action, scope, and side effect with no filler. Every clause earns its place.

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 six parameters, only one required, no annotations, and no output schema, the description covers the action but not clip-targeting resolution or the shape of the verification result. It is adequate but leaves the agent to infer how to address a specific clip.

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 all six parameters are already documented, and the description only adds the '(mute)' gloss on enabled. It does not explain how the five optional clip identifiers (clip_name, clip_index, clip_node_id, track_type, track_index) combine or which are needed to target a clip, so it adds little beyond the schema.

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?

States a specific verb pair (enable/disable) on a specific resource (timeline clip) scoped to the active sequence, and adds the verification behavior. This is clearly distinguishable from generic siblings like set_supported_clip_property or set_opacity, which mutate different attributes.

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 only usage context is the implicit 'in the active sequence' scoping; there is no statement of when to prefer this over set_supported_clip_property, no prerequisites, and no guidance on when the tool should not be used. The alternative of just muting via a property setter is left unaddressed.

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