dedupe_report

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

The description conveys important matching behavior (ignoring remaster/edit suffixes) and implies that the tool is a report rather than an actual removal, but it never explicitly states that no changes are made. With no annotations, the description carries the full burden of disclosing side effects, so the ambiguity about whether it is read-only or returns a list without modifying anything prevents a higher score.

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 very short and contains no filler, capturing the essential matching rule, scope, and output. However, it is a fragment rather than a complete sentence, and the phrase 'Duplicate tracks' could be misread as a command to duplicate tracks. Still, it is compact and front-loaded.

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 zero-parameter report tool, the description states the scope (each playlist), the matching logic, and the output (ids to remove). But because there is no output schema or annotations, the description must clarify the return format and side effects; it does not explicitly say whether this is a read-only list and what the exact response structures. This is a meaningful gap, yet the core intent is adequately conveyed.

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 tool has no parameters and an empty input schema, so there is no parameter documentation gap. The schema description coverage is 100%, providing a safe baseline of 4; the description does not introduce any conflicting parameter information.

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 identifies the resource (duplicate tracks inside each playlist) and the deliverable (ids to remove), and the key matching rule is specified. It is clear enough to distinguish from siblings like remove_tracks and merge_playlists, but it lacks an explicit verb like 'report' or 'find', which slightly weakens the clarity from a 5.

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 no explicit guidance on when to use this tool versus alternatives such as remove_tracks or summarize_playlist. There is no mention of preconditions, exclusions, or situations where a different tool would be more appropriate. The purpose is somewhat implied by the wording, but the description does not direct the agent to use the right sibling.

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