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

Adds substantial context beyond the annotations: delete is permanent and requires user agreement before confirm=true, writes are blocked on read-only accounts, and the caller should render the full menu after get/save. This tells the agent about irreversible effects and workflow sequencing that destructiveHint alone does not convey.

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?

Four dense sentences, front-loaded with the action vocabulary and ending with return shapes. Nothing is redundant; each clause carries routing, safety, or output information.

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 16-parameter tool with no output schema, the description supplies the return shapes, the read/write action split, the delete safety protocol, and the post-call display rule. That is enough for an agent to invoke it correctly without further inference.

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 the baseline is 3, but the description adds meaning by grouping the action enum into read vs write actions and by mapping the confirm parameter to the delete flow. It also documents the return shapes tied to list vs get. The remaining per-parameter semantics are left to the schema.

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 set and resource ('Create, read, edit, share or delete the user's saved menus') and scopes it as undated, which implicitly separates it from the dated planning sibling. It enumerates the concrete read and write actions, so an agent can tell what it covers. It stops short of naming plan_menu as the alternative, which keeps it from a 5.

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?

Explicitly splits reads (list, get) from writes (save, add_entry, fill, etc.) and warns that writes are blocked on read-only accounts. It also gives the operational rule 'show the whole menu after get/save' and the delete confirmation protocol. No explicit when-not or named alternative, so not a 5.

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