get_session_tracks

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 states that it returns a list of tracks 'with performance context,' which adds some behavioral detail, but it does not discuss side effects, permissions, or pagination behavior. As a simple read operation, this is acceptable but not rich.

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 compact with a clear primary sentence, then structured Args and Returns sections. It contains no unnecessary words and is front-loaded with the main verb and resource.

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?

The tool has one parameter and an output schema is present, so the description covers the essential purpose, parameter, and return type. It is complete for a simple getter 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?

Schema coverage is 0%, so the description must compensate. The Args section explains session_id as 'The session's unique identifier,' which adds meaning beyond the parameter name. The first line also ties the parameter to a 'specific DJ history session,' providing clear context for its use.

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 uses a specific verb 'Get' with a clear resource 'tracks from a specific DJ history session,' distinguishing it from sibling tools like get_playlist_tracks and get_track_details. The phrase 'DJ history session' clarifies the domain and scope.

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 implies usage context: this tool is for retrieving tracks from a DJ history session using a session ID. However, it does not explicitly mention alternatives or exclusions compared to sibling tools, 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.
