validate_playlist_rules

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

With no annotations provided, the description carries full burden. It implies a non-destructive dry-run via 'Dry-run validation', but lacks details on authentication, rate limits, side effects, or what happens with invalid inputs. More behavioral context is needed.

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 description is exceptionally concise: one sentence and an example. Every element is purposeful and front-loaded, with no unnecessary verbiage.

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?

Given the tool has an output schema, required freeform object, and sibling tools with overlapping domains, the description is too sparse. It omits explanation of the return value, exact semantics of the rules, and what constitutes valid track_ids. More completeness is needed for effective use.

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 compensate. The example 'rules' object provides concrete values, adding meaning to the freeform parameter. However, 'track_ids' remains completely undescribed, leaving ambiguity about expected format or constraints.

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 clearly identifies the tool as a dry-run validation for playlist rules, specifying verb and resource. The example hints at diversity and mood constraints, distinguishing it from sibling tools like assess_playlist_quality or analyze_library. However, it could be more explicit about what 'diversity and mood' specifically entail.

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 description provides no guidance on when to use this tool versus alternatives, such as analyze_library or assess_playlist_quality. There is no mention of prerequisites, context, or situations where this tool should be preferred or avoided.

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