Update asset collection

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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the safety profile is largely covered. The description adds no behavioral context beyond that — no mention of the destructive overwrite semantics, the requirement to set confirm=true, or the idempotency key for retries, all of which matter for a 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?

It is a single short sentence with zero waste, which is structurally fine and front-loaded. But the brevity comes at the cost of under-specification rather than being a tight summary, so it is merely adequate.

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 12-parameter mutation tool with a nested/union body, a confirm flag, and an idempotency key, the description omits the mutually exclusive body-input modes and the confirm requirement. Annotations cover the safety hints, but the invocation-relevant complexity is left entirely to the schema.

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 the baseline is 3; the description adds no parameter-level meaning beyond what the schema already documents. The genuinely tricky union of flat flags vs. payload vs. payload_file is described only in the schema, not the description, so nothing extra is contributed.

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 ('Update asset collection') scoped to the authenticated user's fal Assets library, which is clearer than a tautology. However it does not say what can be changed (name, color, icon, description, cover image, filters) nor distinguish itself from same-resource siblings like move_asset_collection, favorite_asset_collection, or update_asset_tag.

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 guidance on when to use this tool versus alternatives. Nothing explains how it differs from move_asset_collection, favorite_asset_collection, or the create/get/delete collection siblings, and no prerequisites or exclusions are stated.

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