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

Annotations only flag destructiveHint=true and openWorldHint=true; the description adds the crucial behavioral detail that approval hands drafts to an external scheduler that publishes on its own timing, plus the requirement to get user confirmation. It still does not say whether approval can be undone or what happens to drafts that fail to schedule, so it stops short of full disclosure.

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 zero filler, front-loading the action and its consequence before the confirmation caveat. Every sentence earns its place.

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 destructive, open-world mutation with no output schema and an undocumented parameter, the definition covers the confirmation requirement and the external publishing model but omits batch limits, failure behavior, and reversibility. Adequate to act safely on the confirmation front, incomplete on the mechanics.

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 carry parameter meaning, and it says nothing about postIds. The agent cannot learn from the text that these are draft IDs, that the array is capped at 20 items, or whether partial or invalid IDs are tolerated.

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 names a specific verb+resource pair ("Approve saved drafts") and explains the downstream effect: sending to the user's linked scheduler for publishing on its schedule. This is clearly distinct from siblings like reject_drafts or save_drafts, though it never explicitly contrasts with send_post_now, which appears to be the closest alternative.

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 one concrete usage rule: "Ask the user to confirm first," which is a real prerequisite for a destructive action. However, there is no guidance on when to choose this over send_post_now (which presumably publishes immediately) or how it relates to score_drafts, leaving the selection decision largely implied.

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