Ase Merge Layer Down

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It names the operation and an edge case but does not reveal that merge-down typically removes/consumes the upper layer, or mention any undo/permission implications, leaving destructive consequences implicit.

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 with no filler. Every phrase contributes either the action or a necessary constraint.

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 simple two-parameter tool with an output schema, the description covers the core action and the key precondition. It is not fully complete because the destructive outcome and the absence of any sibling comparison leave an agent to infer important consequences.

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 0%, so the description must compensate. It adds little beyond the schema: 'layer' hints at layer_name, and the bottom-layer restriction gives one constraint, but sprite_path is left entirely unexplained and no format or relationship is described.

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 states a precise operation ('Merge a layer into the layer directly below it') with a specific resource and an explicit constraint ('must not be bottom'). This clearly differentiates from sibling tools like ase_flatten_layers and ase_reorder_layer.

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 implies when to use the tool: when a single layer should be merged downward into its immediate neighbor. However, it offers no explicit guidance about alternatives (e.g., ase_flatten_layers for merging all layers) or exclusions beyond the bottom-layer restriction.

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