approve_draft

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

No annotations are provided, so the description carries the full behavioral burden. It does disclose one genuinely non-obvious side effect: preference-like comments get stored in the voice profile. However, for a mutation/state-change tool it omits whether approval is reversible, whether it triggers sending or publishing, what permissions are required, and what the result looks like.

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, front-loaded with the action and followed by the side effect, with no filler. It is efficient, though the brevity edges toward under-specification rather than optimal density.

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 mutation tool with no annotations, no output schema, and zero parameter documentation needs materially more description than this. The agent still does not know the required prior state, whether approve triggers delivery, or what channel/seed_id mean in context.

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% for all three parameters, so the description must compensate and largely does not. It only obliquely characterizes the comment parameter as carrying preference information; seed_id and channel (with its four-value enum) go entirely unexplained, leaving the agent no guidance on scope or routing.

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?

"Approve a ready draft" gives a specific verb (approve) and resource (draft), and the qualifier "ready" hints at a state precondition. It is distinguishable from siblings like mark_draft_ready or request_revision, though it never explicitly says what approval does downstream (publish, send, schedule).

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 word "ready" implies the draft must first be marked ready, which is weak but real usage guidance. There is no explicit when-not to use it, no mention of alternatives such as mark_draft_ready or request_revision, and no statement of what happens after approval versus those paths.

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