ygo_slice_batch_art

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

No annotations are supplied, so the description carries the whole burden, yet it says nothing about side effects: it writes files to outputDir, but overwrite behavior, required pre-existing artifacts, and error handling on count mismatches between grid tiles and manifest entries are all undisclosed. The single sentence gives an agent no operational context for a file-producing mutation.

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?

One sentence, front-loaded with the primary action and free of filler. It is efficient but slightly overloaded by bundling two distinct operations (slicing and SVG embedding) without signaling that both occur.

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 three fully described params, no annotations, and no output schema, the description covers the core action but omits what an agent would need to call it correctly: the two-phase nature of the operation, what appears in outputDir, and how failures surface. Adequate but with clear gaps for a file-writing tool.

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 100%, so all three parameters are already documented in structured form; the description adds only the loose mapping of 'grid image' to gridImagePath and 'matching' to the manifest's per-card pairing. It adds no format, sizing, or alignment detail beyond the schema, so the baseline 3 applies.

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 gives a concrete verb pair ('Slice ... and embed') against a concrete resource ('grid image' -> 'individual square artworks' -> 'SVG card'), which is far more specific than the bare tool name. It falls short of 5 because it never distinguishes itself from the close sibling ygo_slice_art_grid, leaving ambiguity about which slicing tool to pick.

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?

There is no explicit when-to-use or when-not-to-use statement. Pipeline ordering is only hinted at indirectly through the schema's note that the manifest comes from ygo_generate_batch_art_prompt, and the description itself says nothing about prerequisites or about the ygo_slice_art_grid alternative.

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