playlist_clone_snapshot

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

With no annotations provided, the description carries the burden of behavioral disclosure. It reveals key traits: the operation is non-destructive, items restore by URI, catalog-removed items are skipped automatically, and the quota cost is '0 GETs + create + chunked adds.' This is strong transparency for a mutation-adjacent tool, though it stops short of covering permission requirements, error behavior, or the default dry-run preview flow.

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 tight sentences plus a quota line. Every element earns its place: the purpose and safety guarantee are front-loaded, followed by the URI-copy behavior and the cost disclosure. There is zero filler or 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 7-parameter tool with no output schema and no annotations, the description covers the core purpose, safety trait, and quota well. Yet it omits useful context such as the dry_run default (a preview that changes nothing unless explicitly committed) and does not contrast with overlapping sibling restore tools. These gaps matter because agents need to know this tool plans by default and how it differs from other snapshot-restore operations.

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 100%, so every parameter is already documented with meaning. The description adds only a generic reference to 'local backup snapshot' and does not elaborate on parameters beyond what the schema provides. Baseline 3 is appropriate; the schema does the heavy lifting.

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?

Opens with a specific verb and resource: 'Restore a playlist from a local backup snapshot as a NEW playlist.' The phrase 'clone, don't clobber' crisply captures the tool's central non-destructive behavior and distinguishes it from overwrite-style restores. An agent can immediately understand what this tool does and how it differs from a plain restore.

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 gives a clear context: use this when you want to restore a saved playlist as a new, separate playlist rather than overwriting a live one. The 'never overwrites the live one' clause implies a safe-clone use case among many snapshot/restore siblings. However, it never explicitly names alternative tools (e.g., restore_playlist_from_snapshot, apply_snapshot_changes) or states when not to use this one, so it stops short of full guidance.

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