timetree_create_memo

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

With no annotations, the description carries the full burden. It discloses the important confirmation gate and clearly implies a write operation, but it does not comment on side effects, permissions, reversibility, or what the response might be. Some useful guardrail context is provided, but substantial behavioral detail remains uncovered.

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 description is concise and front-loaded: the action first, the confirming guardrail immediately after. There is no waste or redundant detail.

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?

A 10-parameter write operation with no annotations and no output schema is under-equipped with a two-sentence description. The description does not clarify how to obtain calendar_id, how the checklist items are structured, or what the result will be, leaving too much unspecified.

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 only 10%, so the description must compensate but only mentions 'confirm'. Other parameters like calendar_id, label_id, checklist, and virtual_user_attendees are neither explained in the description nor described in the schema beyond names and basic types. This leaves the agent to infer semantics for most of the 10 parameters.

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 ('Create') and the resource ('a TimeTree memo'), clearly identifying the operation. This distinguishes it from sibling tools like timetree_update_memo, timetree_delete_memo, and timetree_create_event without ambiguity.

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?

The description makes the core use case clear—creating a memo—and adds a mandatory prerequisite ('Requires confirm=true'). However, it does not contrast with alternatives or mention when to use list_memos/update_memo instead, leaving the comparative guidance implied.

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