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

Annotations cover the mutation/safety profile (not read-only, not destructive, not idempotent), and the description adds genuine value beyond them: drafts are non-committal and reversible, and it discloses the return payload (draft_hash plus release_rules). It doesn't clarify what happens to fields omitted from a re-save, which would fully close the loop.

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, front-loaded with the draft concept, and the details about cost/reversibility and the return values follow logically. Slightly dense in the third sentence but nothing is wasted.

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?

No output schema exists, so the description carries the return burden and does so (draft_hash, release_rules with example rule areas). Combined with annotations covering safety and a rich input schema, an agent has enough to invoke it correctly; only the re-save/overwrite semantics are unstated.

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 75% and the nested 'release' object is well documented in the schema itself, including a pointer to get_requirements. The description adds no parameter-level syntax or format detail, so it is at the baseline for a well-covered 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?

States a specific verb (write), resource (release details for a track or album), and a distinct mode (as a DRAFT), which separates it from the update_track/update_album siblings that presumably mutate live data. An agent knows exactly what this produces without opening the schema.

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 the context for using it: a draft is free, editable, and goes nowhere until the artist commits, and it flags what the release still needs before submission. It does not name a specific alternative submission tool to use afterward, so it stops short of full when/when-not routing.

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