snapshot_registry_report

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does describe what the tool surfaces (snapshot ids, timestamps, track counts, naming anomalies) and 'view' reasonably implies a read-only operation. However, it does not explicitly confirm the absence of side effects, explain how 'naming anomalies' are determined, or note any filesystem/registry assumptions.

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 one dense sentence with the main purpose front-loaded ('Registry view of every local snapshot') before listing the delivered fields. There is no filler or redundant repetition of the tool name. The trailing clause about naming anomalies is slightly vague but still useful.

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 tool with one optional, fully-documented parameter and no required inputs, the description provides enough detail to understand what the tool returns and when its registry-oriented view is relevant. It does not specify the exact output shape or define what counts as an anomaly, but these are minor gaps for such a low-complexity tool.

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 single parameter response_format is fully documented by the input schema with an enum, a default, and per-value descriptions, so schema coverage is 100%. The description adds no parameter-specific meaning, but none is necessary here because the schema already handles 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 identifies a specific resource ('every local snapshot') and the exact contents: per playlist snapshot ids, taken_at, track counts, and naming anomalies. This separates it from simple list tools by adding the anomaly-detection angle. It is slightly weakened by being phrased as a noun ('Registry view') rather than an explicit verb, and by not naming any sibling to contrast with.

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?

There is no guidance about when to choose snapshot_registry_report over closely related siblings like list_playlist_snapshots, snapshot_stats_report, snapshot_integrity_report, or list_saved_snapshots. The word 'Registry' implies an overview use case, but no conditions, exclusions, or alternative tools are stated.

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