sequencer.modifier_set

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

No annotations are provided, and the description fails to disclose any behavioral traits. It does not indicate whether the operation is destructive, reversible, or requires specific permissions. For a mutation tool, this is a significant gap.

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 sentence with no redundancy, which is concise. However, it sacrifices completeness for brevity. It is not verbose, but it could be restructured to include more guidance without adding length.

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 4 required parameters, no output schema, and no annotations, the description is far from complete. It omits details on the expected format of 'value', the effect scope, and any side effects. The agent would need to rely on parameter names alone, which is insufficient.

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 coverage, the description should explain parameter meanings, but it adds nothing beyond the param names. The 'value' parameter expects JSON, but the description does not clarify format or constraints. The names are somewhat self-explanatory, but the description does not compensate for the lack of schema descriptions.

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 specifies the action ('Set'), the resource ('one RNA property on a strip modifier'), and implies granularity ('one property'). It clearly distinguishes from adding/removing modifiers, though it could more explicitly contrast with sibling tools like 'sequencer.modifier_add'.

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 description offers no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, nor does it differentiate from similar setter tools like 'modifiers.set' or 'sequencer.strip_set'.

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