playlist_reverse

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

With no annotations, the description carries the burden of behavioral disclosure. It does add useful context: 'atomic replace' indicates the mutation is all-or-nothing, and the quota line hints at the required API verbs. However, it omits reversibility, side effects, and the role of dry_run as a safety preview.

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?

The first sentence is concise and front-loaded. The second sentence is redundant and confusing, repeating reverse_playlist_plan twice in a short span without adding useful structure or guidance.

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 mutation tool with no annotations and no output schema, this description is too thin. It does not explain what a successful call returns, what happens on failure, whether the original playlist can be restored, or how this tool relates to reverse_playlist_plan operationally.

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 only 50%, and the description adds no parameter-level meaning beyond the schema. playlist_id is left as an undocumented string, and dry_run is only explained in the schema, not reinforced or clarified in the description.

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 states a specific action and resource: 'Reverse a playlist in one atomic replace.' This clearly indicates an apply-style mutation. However, the reference to reverse_playlist_plan is ambiguous and does not clearly distinguish this tool from that sibling.

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 only nod to an alternative is 'See also: reverse_playlist_plan,' but it gives no guidance on when to use this tool versus the plan variant. The phrase 'Also covers: reverse_playlist_plan' is confusing rather than instructive.

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