remove_favorite

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

No annotations are provided, so the description carries the full burden. It does not say whether removal is permanent, what happens when the index is out of range, whether the list re-indexes after removal, or what the operation returns — all critical for a destructive mutation.

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?

A single well-formed sentence with no padding, and the key qualifier about the index origin is placed before the reader needs it. Nothing is redundant.

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?

An output schema exists, so return values need not be described, but for a one-parameter destructive tool with zero annotation coverage the description is thin. It omits index base, re-indexing behavior, error conditions, and confirmation/irreversibility, leaving meaningful gaps an agent could stumble on.

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 description coverage is 0%, so the description must compensate, and it does add meaning: the 'index' is a position within the favorites list rather than a track ID. However, it leaves the base (0- vs 1-based) and whether it matches list_favorites ordering unspecified, which is the ambiguity that matters most.

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 ('Removes a track from favorites') plus the addressing mechanism ('using its index number from the favorites list'). It is distinguishable from siblings such as list_favorites and add_search_result_to_favorites, though it never explicitly contrasts itself with them.

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 phrase 'index number from the favorites list' implies the workflow (call list_favorites first, then remove by position) but never says so explicitly or names the alternative tools. There is no statement of when not to use it, or what to do if the track is not currently a favorite.

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