delete_playlist_snapshot

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

Without annotations, the description carries the full burden, and it discloses the key safety behavior: dry_run=true by default and that it 'only reports what would be removed.' This is meaningful transparency for a deletion tool. It could go further by stating irreversibility or explicitly confirming that dry_run=false commits the deletion, but the dry_run mention is already strong.

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 core purpose and safety behavior are front-loaded in a compact first clause, and the snapshot guide condenses a useful lifecycle map. It is slightly run-on and missing a separator before 'Snapshot guide,' but overall the description earns its length.

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 relatively simple single-file deletion tool, the description covers what it does, the dry_run safety mechanism, and how it relates to sibling snapshot operations. The lack of an output schema is not a major gap because the schema already defines response_format, and no other critical operational context seems missing.

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 the input schema already documents snapshot, dry_run, and response_format thoroughly. The description adds little beyond restating dry_run's default behavior, which is already in the schema. Baseline 3 applies.

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 specific verb ('Delete') and resource ('one local playlist snapshot file'), and the qualifying word 'one' distinguishes it from batch/prune operations like prune_old_snapshots. The snapshot guide further positions it within the create/read/diff/restore lifecycle.

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 clear lifecycle context by listing related snapshot tools: take_playlist_snapshot for create, list_saved_snapshots for list, read_playlist_snapshot for read, diff/restore tools. This helps an agent route to the right operation. However, it does not explicitly exclude bulk alternatives like prune_old_snapshots or snapshot_retention_plan.

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