fl_list_playlist_tracks

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

The description adds meaningful context beyond the annotations by specifying one-based indexing and that the result includes each track's controllable state. The annotations (readOnlyHint, openWorldHint, idempotentHint, destructiveHint) already cover safety, so the description's extra detail about indexing and content is sufficient and non-contradictory.

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?

A single, efficient sentence with no wasted words. The action and resource are front-loaded, and the specific qualifiers (one-based, controllable state) are included without redundancy.

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 zero-parameter read-only listing tool with an output schema available, the description fully covers what the tool does and what it returns. No additional context (e.g., pagination, limits) is necessary for an agent to call it correctly, and the annotations cover the safety profile.

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?

The tool has zero parameters, so schema coverage is trivially 100%. The description does not need to explain parameter semantics, and the baseline for 0 parameters is 4. The description's mention of 'one-based' and 'controllable state' adds context about the output rather than parameters, which is not required here.

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 clear action ('List'), the specific resource ('Playlist tracks'), and defines the scope ('every one-based' and 'its controllable state'). It distinguishes this from sibling list tools like fl_list_mixer_tracks and fl_list_patterns by naming the resource type explicitly.

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 (if you need playlist tracks, use this) but provides no explicit when-to-use guidance or alternatives. It does not mention cases where the agent should prefer fl_list_mixer_tracks or fl_list_patterns, nor any exclusion conditions.

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