flip_sprite

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

No annotations provided, so description must carry full behavioral burden. It does not disclose whether flipping is destructive, if it modifies the sprite in place, or what the outcome looks like. The description is too brief to convey important behavioral traits.

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?

Very concise, one descriptive sentence plus a parameter hint. No redundancy, but could be slightly more structured. Efficient use of space for the limited information provided.

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 no output schema and simple parameters, the description is partially complete. It lacks behavioral details (e.g., side effects, return value) that would help an agent use it safely. Adequate but not thorough for a tool with many siblings.

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 0%, so description must compensate. It explains the 'direction' parameter with example values ('horizontal' or 'vertical'), which adds value. However, it ignores the 'filename' parameter entirely, leaving it undocumented. Partial coverage but minimally helpful.

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?

Description clearly states the tool flips the entire sprite, using a specific verb and resource. It does not explicitly distinguish from sibling tools like mirror_layer or rotate_sprite, but the action is distinct enough for an agent to infer the purpose.

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 on when to use this tool versus alternatives. No prerequisites, when-not-to-use, or context provided. The description is purely functional, leaving the agent to guess appropriateness.

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