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

With no annotations, the description does useful work by disclosing the effect target (brush inventory, not canvas pixels) and the return value (brush_pack_id). However, for a mutation it omits whether an import merges with or replaces existing brushes, whether it is reversible, and any permission or failure-mode expectations.

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?

A single tight sentence with the effect scope front-loaded after the action, and every clause (import, return id, non-pixel effect) carries information. No filler.

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?

It is a low-complexity tool (2 optional params, no nesting) and the description covers the action, the returned id, and the effect scope, which is much of what matters. Without annotations or an output schema, though, it should say more about overwrite/merge behavior on an existing brush inventory.

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 100%, so both source_path and source_files are already documented in the schema, including the mutual-exclusion hint. The description adds no further meaning about formats, path semantics, or precedence, 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 pairs a specific verb (import) with a specific resource (.abr assets) and names the concrete artifact produced (brush_pack_id with verified presets). It also explicitly scopes the effect away from canvas pixels, which sharpens it against pixel-editing siblings, but it doesn't name a direct alternative such as list_brush_presets or brush_pack_profile.

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 phrase 'import supplied .abr assets' implies the precondition of having .abr files, and the 'not canvas pixels' clause implies this is for inventory setup rather than drawing. There is no explicit when-to-use/when-not guidance or any routing to sibling tools like brush_pack_profile that might be the correct next step.

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