ledfx_add_scene_to_playlist

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

No annotations are provided, and the description does not disclose behavioral traits like idempotency, error handling (e.g., if playlist or scene doesn't exist), or side effects. The agent is left to guess the tool's behavior beyond the basic action.

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 a single sentence directly stating the purpose, which is concise. However, it could be structured better by explicitly listing the required parameters or providing a usage example.

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 description lacks information about return values, success/failure indicators, and error conditions. For a state-mutating tool with no output schema, this is incomplete. Sibling tools like ledfx_get_playlist have more detailed descriptions.

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 100%, so the parameter descriptions already explain playlist_id, scene_id, and duration_ms. The tool's description adds no additional meaning beyond what is in the schema, meeting the baseline but not exceeding it.

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 the action 'Add' and the resource 'scene to an existing playlist'. It distinguishes from siblings like ledfx_create_playlist, ledfx_delete_playlist, and ledfx_start_playlist, which deal with different aspects of playlists.

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 like ledfx_upsert_playlist or ledfx_patch_playlist_items. It does not mention prerequisites, such as requiring an existing playlist, or when to prefer batch operations.

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