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

Annotations supply destructiveHint=true, and the description adds nothing beyond the HTTP endpoint (POST /folders). It does not disclose permission requirements, duplicate-name behavior, what the accessLevel default is, or what the call returns. With annotations present, the description is expected to add context and does not.

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?

Two short sentences, front-loaded with the purpose and with zero filler. The trailing "Dub: POST /folders" is of marginal value to an agent but costs 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?

For a simple three-parameter create tool with full schema coverage and no output schema, the description covers the essentials of what the tool does. It falls short on when to use it and on the behavioral implications of the declared destructiveHint, which an agent would want before creating workspace-organizing resources.

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% and all three parameters (name, accessLevel, description) are documented in the schema, so baseline 3 applies. The description provides no additional parameter meaning, such as explaining when to set accessLevel or what each enum value implies.

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 states a specific verb and resource ("Create a folder") and adds scope with "for grouping links," which tells the agent what folders are for relative to the link-centric siblings. It does not explicitly distinguish itself from dub_create_link or dub_create_tag, but the resource noun 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?

There is no guidance on when to create a folder versus using tags (dub_create_tag) or how folders relate to link organization, and no mention of prerequisites such as workspace permissions. The agent must infer usage entirely from the name.

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