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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the description does not need to restate the safety profile. It does not add important behavioral context such as whether refitting or ink conversion is irreversible, what gets destroyed, or how existing geometry is affected. It does not contradict the annotations.

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 single sentence is front-loaded and free of filler, which is good for scanning. However, it is so terse for an 11-parameter destructive operation that it reads as under-specified rather than appropriately concise.

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?

For a destructive, 11-parameter path operation with no output schema, the description is far too thin. It omits mode semantics, parameter roles, expected effects, and any explanation of what the operation changes on the document.

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 tool has 11 parameters with 0% schema description coverage, and the description explains none of them. It mentions ink and missing handles/curves but does not map these to shape_id, mode, corners, protect, tension, tolerance, corner_angle, display_width, split_extrema, or subpath_index.

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 names three concrete operations—filling missing handles, refitting curves, and turning a stroke into ink—so the broad purpose is inferable. However, it never explicitly states that it operates on a path/shape identified by shape_id, and it does not distinguish itself from siblings such as edit_path, inspect_path, create_path, or offset_path.

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 guidance on when to use this tool versus alternatives, no exclusions, and no prerequisites. The description only hints at capabilities and leaves routing decisions entirely to inference.

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