export_spritesheet

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

No annotations are provided, so the description must disclose behavioral traits. It does not mention side effects (e.g., file overwriting, file locking), error conditions (e.g., missing file, invalid sheet type), or whether the operation is read-only or modifies the original file. This lack of behavioral context leaves the agent underinformed.

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 compact docstring with a two-line intro followed by a bulleted Args list. Every sentence is informative with no filler. Slight improvement would be possible by grouping similar parameters, but overall it is well-structured and efficient.

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?

The description covers parameter semantics decently but lacks behavioral details like error handling, file overwrite behavior, and the structure of the optional JSON output. Given the absence of annotations and output schema, more contextual information would help the agent fully understand the tool's effects and constraints.

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 carries the full burden. It explains each parameter: filename (input file), output_filename (PNG path), sheet_type (layout options), data_filename (optional JSON), scale, padding, and tag_name. However, sheet_type options ('horizontal', 'vertical', 'rows', 'columns', 'packed') are listed without explanation of differences, slightly reducing clarity.

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 'Export frames as a sprite sheet, optionally with a JSON data file.' This is a specific action (export) on a specific resource (frames) to produce a sheet, distinguishing it from sibling tools like export_frame, export_layers, and export_sprite.

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 provides a list of parameters but does not include any explicit guidance on when to use this tool versus its alternatives (e.g., export_frame, export_layers). There is no mention of prerequisites, limitations, or conditions that favor this tool.

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