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

The annotations only say readOnlyHint=false and destructiveHint=true; the description adds the meaningful behavioral details: it returns while publishing, wait controls synchronous behavior, drafts need a target account, and already-sent posts return post_not_editable. This is exactly the kind of operational context an agent needs beyond the raw annotations.

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?

Three sentences with no filler. The main action is front-loaded, then the async behavior, then the preconditions and failure mode. Every sentence contributes information an agent cannot infer from the schema alone.

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 simple 3-parameter action with no output schema, the description covers the key operational concerns: async versus blocking behavior, draft requirements, error semantics, and id/workspace disambiguation. Referencing 'like publish' is acceptable because publish is a known sibling that documents the shared return semantics.

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 real value: it explains the accepted id forms (publish id, channel id, or post link), clarifies that wait behaves 'same as on publish,' and tells the agent to omit workspaceId unless multi-workspace and not to re-ask the person. That meaningfully extends 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?

The description opens with a specific verb and resource: 'Send a scheduled or draft post right now instead of waiting.' It clearly distinguishes this from the broader publish/update/retry sibling family by focusing on immediate publication of scheduled or draft content.

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 clear usage context: use this when you want a scheduled or draft post sent immediately, and pass wait: true if you need to block for the result. It also flags draft prerequisites and the already-published error case. It references 'like publish' but does not explicitly state when to prefer publish_now over publish, so it stops short of full alternative routing.

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