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

The annotations already declare the operation is a non-read-only, idempotent, destructive write, so the safety profile is largely covered. The description adds only the ISO date format hint and nothing about what the destructiveHint implies (e.g. whether an existing status is overwritten) or permission needs, so it adds modest value.

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 short sentences with the action front-loaded and no wasted words. It is terse to the point of under-specification rather than overly verbose.

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?

With no output schema and annotations covering safety, the description is minimally adequate but leaves real gaps: what happens when date is omitted (schedule immediately?), what the required id refers to, and how this differs from the listing/rescheduling siblings.

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 33% (only workspaceId is documented), so the description carries extra burden. It usefully specifies the date format (YYYY-MM-DD), but says nothing about the required id parameter, leaving the most important parameter to inference.

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 ('Set a post status to scheduled'), which is unambiguous on its own. However, it does not differentiate from close siblings like reschedule_post or unschedule_post, which an agent could easily confuse with it.

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?

There is no guidance on when to use this versus reschedule_post, unschedule_post, or approve_post. The only usage-adjacent detail is that the date is optional, but no condition is given for omitting it or for choosing among the scheduling siblings.

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