flip_sprite

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

With no annotations, the description must convey behavioral traits. It states that flipping applies to the active sprite or a specific layer/frame, but does not disclose whether the operation is in-place/destructive, requires an open sprite, affects undo history, or what the return value is. 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 a single, appropriately sized sentence with no filler. It front-loads the core operation and adds optional targeting and direction details efficiently.

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?

Despite being a simple tool, the description omits critical context for an editor operation: it is presumably destructive/in-place, requires an open sprite, and may interact with frame/layer scoping in non-obvious ways. No output schema or annotations to fill gaps, so the description alone is incomplete.

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 schema has zero property descriptions, so the description must compensate. It explains that layer and frame target specific components, and direction controls orientation. However, it does not clarify defaults (e.g., if direction is omitted, is horizontal implied?) or whether layer/frame are mutually exclusive. Partial semantics provided.

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 a specific action (Flip) on a specific resource (active sprite, or specific layer/frame), with orientation options. It distinguishes itself from sibling tools like rotate_sprite by focusing on mirroring rather than rotation.

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?

No guidance is given on when to use this tool versus alternatives (e.g., rotate_sprite). The description implies flipping is the intended use but does not mention prerequisites, exclusions, or related tools. No explicit context for decision-making.

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