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

Adds substantial behavior beyond the annotations: same minutes are billed as the original order, a new order_id is returned, edits always derive from the original recording (so instructions must be self-contained), and show notes/clips are only regenerated when requested. These cost, idempotency, and non-regeneration semantics are exactly what annotations cannot convey.

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?

Six short sentences, front-loaded with the core action and return value. All sentences earn their place; a minor trim (the repeated 'made from the original recording' idea) would tighten it further.

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 non-read-only, open-world mutation tool with no output schema, the description covers the trigger (finished order), the cost model, the return values (order_id, edited audio), and where to observe results. Nothing essential to calling it correctly is missing.

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 meaning: 'one request carries everything that is to be different' tells the agent instructions must be complete rather than incremental, and it reinforces that order_id must be the original order, not an earlier revision.

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+resource ('Re-edits a finished order') plus examples of what instructions look like. It is clearly distinguishable from siblings like barevalue_submit_url (new orders) and barevalue_status (progress polling).

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?

Explains that this is for finished orders, that it creates a new order from the original recording, and explicitly routes progress checks to barevalue_status. It does not explicitly state when NOT to use it (e.g., for in-flight or already-revised orders, though the order_id note implies it).

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