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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the description's marginal contribution is the quota context (3 / 20 / unlimited by plan) and the note that each view bundles folder, tag, status, search, and date-range filters. That is genuinely useful context an agent could not infer from the schema, though nothing is said about ordering, pagination, or the shape of returned view records.

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?

Three short sentences, front-loaded with the core action, with no filler or redundancy. The quota sentence is slightly tangential for a pure listing call and arguably belongs with create_saved_view, which keeps this just short of a 5.

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 zero-parameter, read-only list tool with no output schema, the definition gives enough to call it confidently: what is listed, what each item contains conceptually, and the account-scoped nature. It stops short of describing the returned record fields or ordering, which leaves a small gap given the absence of an output schema.

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 takes zero parameters, so the schema carries no semantics to explain and the baseline of 4 applies. The description correctly implies an account-scoped, unfiltered listing with no argument surface to document.

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 and resource ("List the saved link-list views") and immediately glosses the resource as "filter + sort presets", so an agent knows this is a read of preset configurations rather than links themselves. The verb makes it distinguishable from create_saved_view, update_saved_view, and delete_saved_view, though it never names them explicitly.

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 by the name and the description text; there is no explicit "use this when you need to enumerate views before applying one" or any pointer to a sibling tool for editing or deleting views. The tier-limit sentence hints at the create-side constraint but does not function as when-to-use guidance for this tool.

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