delete_playlist

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

With no annotations provided, the description carries the full burden of disclosure. It clearly reveals the destructive nature (deleting all contents) and the safety mechanism of dry-run mode. It stops short of detailing edge cases like non-existent playlists or idempotency, but the core behavioral traits are transparent.

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 economically written—two sentences plus a parameter list, all front-loaded with the core purpose. Every sentence contributes essential information: what it does, how to use it safely, and what the args mean. No 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?

For a delete operation with 3 parameters, the description covers the main functionality, the safety default, and the key parameters. An output schema exists so return values aren't needed in the description. The main shortfall is the unexplained db_path parameter, but the tool is otherwise adequately contextualized.

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 schema has 0% description coverage (no parameter descriptions), so the description must compensate. It does so for the two primary parameters: playlist_id (with example format) and dry_run (exact semantics of True/False). However, it omits any explanation for db_path, leaving a gap for that optional parameter.

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 opens with a clear, specific verb and resource: 'Delete a playlist and all its contents.' This distinctly identifies the operation and its scope, separating it from sibling tools like list_playlists or merge_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 critical usage guidance by explaining the dry-run default and how to execute the deletion ('set dry_run=False to actually delete'). This tells the agent how to use the tool safely, though it doesn't explicitly contrast with alternatives or state when not to use it.

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