flip_layer

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

No annotations are provided, and the description does not disclose behavioral traits such as whether the operation is destructive, if it modifies the file immediately, or any side effects. This is a significant gap for a mutation tool.

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 extremely concise, with a clear one-line purpose followed by a minimal parameter list. Every sentence earns its place, and there is no fluff.

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 modifies a layer and has no output schema, the description omits crucial context like return value, error conditions, prerequisites (e.g., file must exist, layer must be unlocked), and how it interacts with frame_index. It is insufficient for an agent to use confidently.

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 description lists all four parameters and adds value by specifying that frame_index starts at 1 and direction accepts 'horizontal' or 'vertical'. However, detailed semantics (e.g., required format for filename, behavior of direction default) are not provided, and schema coverage is 0%.

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 'Flip a layer's image horizontally or vertically' clearly states the action (flip), the resource (layer's image), and the possible directions. It immediately distinguishes from sibling tools like rotate_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 usage for mirroring a layer, but provides no explicit guidance on when to use this tool versus alternatives (e.g., rotate_layer, invert_colors) or when not to use it.

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