goodnotes_get_folder_style

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the actual returned content (color, icon, favorite state) plus the optional enumeration of native choices, but says nothing about failure modes when the path/title does not resolve.

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 front-loaded clause with no filler; the returned fields come first and the optional behavior trails. It is efficient, though one more short clause on the required path/title semantics would have cost little.

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?

With no output schema, the description does the right thing by naming the returned attributes, but for a 3-parameter, 0%-coverage tool it leaves the two required parameters and their validation behavior undocumented. Adequate but with clear gaps relative to its complexity.

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 must carry parameter meaning, yet it only glosses includeChoices as 'optionally listing native color/icon choices'. The required itemPath (a UUID array of up to 12 segments) and expectedTitle (a title guard for the target folder) are left entirely unexplained.

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?

States a specific verb ('Read') and specific resource fields (folder color, icon, favorite state), which distinguishes it functionally from the sibling goodnotes_set_folder_style. It stops short of naming the write counterpart explicitly, but the read-only framing is unambiguous.

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?

Usage is only implied: the read verb suggests this is the inspection step before goodnotes_set_folder_style, and 'optionally listing native color/icon choices' hints at when to set includeChoices. There is no explicit when-to-use or when-not-to-use statement, and no sibling is named as an alternative.

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