playlist_buildSmart

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

No annotations are provided, so the description must shoulder the burden of disclosing side effects. It mentions 'Creates backup' but does not explain what the backup covers, whether existing playlists are overwritten, or any required preconditions. This is a significant gap for a mutation tool.

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 sentences with the primary action front-loaded. Every word adds value; no redundancy or filler.

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?

The tool has a complex nested object, no output schema, and no annotations. The description omits return behavior, prerequisites, and thorough parameter guidance, leaving important context gaps for a mutation tool. It is not completely inadequate but clearly below a fully specified description.

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. It names several rule parameters (energy curve, key progression, BPM range, artist diversity) but does not explain playlistName or other nested fields like max_tracks, include/exclude_tracks, preferred_genres, or min_duration_minutes. Partial compensation, but incomplete.

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 states 'Create a playlist using smart composition rules' with specific rule types (energy curve, key progression, BPM range, artist diversity). This differentiates it from sibling tools like playlist_create or playlist_addTracks.

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 implies usage for algorithmic composition via 'smart composition rules' but does not explicitly state when to use this tool versus alternatives like playlist_create or playlist_addTracks. No exclusion criteria or prerequisites are given.

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