Unfavorite asset collection

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

Annotations already declare readOnlyHint=false, destructiveHint=true, openWorldHint=true and idempotentHint=false, so the safety profile is covered. The description adds only the scoping fact that it applies to the authenticated user's library; it says nothing about the required 'confirm' gate or what an unfavorite actually removes/retains.

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 front-loaded sentence with the action and scope, no filler and no repetition of the title. Nothing could be trimmed without losing information.

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 one-required-parameter mutation with full schema coverage, rich annotations, and no output schema, the description is close to sufficient. It stops short of explaining the confirm-gate behavior or the consequences of the destructive flag, which would be the remaining value-add.

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 100%, so all four parameters (including the non-obvious 'confirm' and 'Idempotency_Key') are already documented in the schema. The description adds no syntax, format, or constraint detail beyond that, so baseline 3 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+resource ('Unfavorite an asset collection') and adds scope ('authenticated user's fal Assets library'), making it clearly distinct from favorite_asset_collection and delete_asset_collection. It does not explicitly name the sibling alternative, but the verb is unambiguous.

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?

No when-to-use, when-not-to-use, or alternative is given. The existence of favorite_asset_collection as the inverse operation is left for the agent to infer, and there is no guidance on prerequisites or reversibility.

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