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

Annotations already declare non-read-only, destructive, idempotent, and closed-world behavior, so the safety profile is covered. The description adds the valuable approval gate, but does not disclose what happens to the previous approved schedule, whether the commit can be reversed, or what state the draft ends in.

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 sentences, purpose front-loaded, followed by the critical precondition. No filler, no repetition of schema or annotation content.

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?

An output schema exists, so return values need not be described, and annotations carry the mutation/safety profile. Combined with the approval gate, the definition is nearly sufficient, missing only the effect on any previously committed schedule and on the draft itself.

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 0%, so the description must compensate. It explains the semantics of confirmed well (a deliberate approval gate), but scheduleId is only inferable from its uuid format and name, with no statement that it must be the current draft's id.

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 — marking the current draft as the approved schedule — which is concrete and actionable. It differentiates implicitly from draft-handling siblings like start_schedule and read_schedule, but never names an alternative 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?

It gives a clear precondition for calling the tool: only pass confirmed=true after the freelancer approves the deposit, later payment dates, and client messaging. That is genuine when-to-use context, though it does not name sibling tools or describe the route for changing an already-committed schedule.

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