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

Annotations already declare readOnlyHint=true and destructiveHint=false; the description reinforces this with the non-obvious detail that it 'opens nothing by itself' and returns instructions instead of a URL. It does not describe the shape or length of the returned steps, but the read-only contract is unambiguous.

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 core behavior and the handoff to cotlet_browser_* are front-loaded, but the trailing 'Milanote's official API: Milanote has no public API and no official MCP server (checked 11 Oct 2026)' is meta-justification that does not help an agent decide or invoke, and the parenthetical '(screens, buttons, fields)' is redundant 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?

For a no-parameter, read-only helper with no output schema, the description covers what it returns (step-by-step UI instructions), what it does not do, and which follow-up tool family to use. Missing only an explicit pointer to the alternative sharing tools that might be cheaper than the browser path.

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?

Zero-parameter tool, so the baseline applies; there is nothing in the schema that the description needs to explain. The description correctly implies the tool needs no target board or account argument, avoiding a false expectation that the caller must supply identifiers.

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+resource (share a read-only link) scoped to 'the user's own Milanote account', and importantly corrects a likely misreading of the name by explaining it only returns step-by-step instructions rather than performing the share. It stops short of naming the nearest siblings (get_sharing, publish_board), so an agent must still infer how this differs from those.

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?

Gives a clear when-to-use and an explicit next step: call this to learn the procedure, then execute it with the cotlet_browser_* tools in the Milanote Cloud Browser. It does not state when NOT to use it (e.g. when a direct API-style tool like get_sharing or publish_board suffices), which is the main gap.

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