ae_set_layer_property

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

Annotations are absent, so the description carries the burden of behavioral disclosure. It only states that a property value is set; it does not explain whether setting a value creates or replaces keyframes, how time interacts with the operation, or what happens if the property path or layer is invalid. The mutation implication is present but thin.

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 short and front-loaded, with the core purpose stated first and usage guidance second. It is appropriately sized, though the missing guidance on alternatives leaves some structure value on the table.

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 large sibling set and absence of annotations, the description is incomplete for correct tool selection. It does not distinguish this tool from ae_add_keyframe or ae_batch_set_property, and it omits key behavioral context about keyframes and time semantics. The schema covers parameters, but the description alone is not enough for reliable invocation.

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 100%, so the schema already documents all parameters. The description adds useful syntax examples for property_path ('Transform.Opacity', 'Transform.Position'), which goes slightly beyond the schema, but it does not clarify value type constraints or the time parameter behavior.

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 ('Set a property value on a layer') and the resource (a layer property). It also gives concrete examples of property paths, which helps distinguish it from general script or batch tools, though it does not explicitly name sibling alternatives.

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 gives syntax guidance ('Use dot notation') but does not explain when to use this tool versus closely related siblings like ae_add_keyframe, ae_set_layer_time, or ae_batch_set_property. There is no mention of keyframing versus static value setting or any exclusions.

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