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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds two useful facts beyond that — the tool performs no action itself and the SoundCloud API route is blocked by an Artist Pro requirement — but says nothing about the shape or length of the returned instructions.

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 workflow statement is front-loaded and earns its place, but 'from ChatGPT, Claude or any AI agent' is filler, and the closing API/credentials sentence with a checked date is tangential detail that dilutes the core message.

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 tool with no output schema, the definition covers what it does, what it returns (instructions), and what it does not do (open anything), which is enough to invoke it correctly. The main omission is any hint about how detailed the returned steps are or how to hand them to the browser tools.

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 takes zero parameters, so there is no parameter semantics for the description to compensate for. Baseline of 4 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?

States a specific verb and resource ('List tracks in the user's own SoundCloud account') and scopes it to the user's own account. The key clarification that it returns step-by-step instructions rather than data is present, though it slightly conflicts with the plain 'list tracks' naming and never distinguishes itself from siblings like soundcloud_list_comments.

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?

Gives a clear workflow: call this to get the steps, then execute them with the cotlet_browser_* tools, and notes that it 'opens nothing by itself'. It stops short of naming when not to use it or pointing to any specific browser tool or sequence.

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