Slskd Search

slskd_search

Search the Soulseek network for music files, albums, or artists, then filter by format and bitrate and rank matches by peer speed and queue.

Instructions

Search the Soulseek network for music files, albums, or artists.

Polls until responses arrive or timeout expires. Filters and ranks matches prioritizing peers with open upload slots, shorter queues, and higher speeds.

A3.8/5.0
Behavior4/5

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

With no annotations, the description carries the full behavioral burden, and it does disclose non-obvious traits: it polls until responses arrive or the timeout expires, and it filters/ranks results by upload slots, queue length, and speed. It omits rate-limit or network-exposure considerations, but the ranking and polling disclosure is genuinely valuable.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with purpose, followed by essential behavioral detail. No filler and every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists so return values need not be explained, and the description covers polling, filtering, and ranking adequately. The absence of annotations leaves the safety/permission profile entirely unstated, which is a minor gap for a read-like network search.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all five parameters are already documented in the schema. The description adds no syntax or format detail beyond that, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (search) and resource (Soulseek network for music files, albums, artists), which is unambiguous. It does not explicitly differentiate itself from siblings like slskd_browse_user, though the network-wide scope implies the distinction.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied — an agent would search before calling slskd_download — but the description never states when to use this versus slskd_browse_user, nor any prerequisites or when not to search. No explicit routing guidance is given.

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