tiktok_mobile_live_effects

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

With no annotations, the description carries the full burden and does disclose meaningful behavioral traits: the catalogue is complete (2,032 assets), there is no paging, and the response body is large. It stops short of stating auth requirements or rate limits, but the payload-size and no-paging warnings are genuinely useful operational context.

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?

Front-loaded with the core action, then the field enumeration. The long list of asset fields is somewhat dense, but it earns its place because there is no output schema and no other place to document the return shape.

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?

With no output schema, the description compensates by enumerating the returned asset fields and stating the catalogue is complete with no paging. Combined with the zero-parameter input, this gives an agent enough to invoke it correctly; only auth/rate-limit context is absent.

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 the baseline is 4. The description correctly states there are no request parameters, which is the only relevant parameter-level information for this call.

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 ('Retrieve TikTok LIVE effects') and immediately scopes it as the complete LIVE effects/sticker asset catalogue. It is distinguishable from tiktok_mobile_live_gifts and tiktok_mobile_trending_effects by resource, though it never names those siblings to disambiguate explicitly.

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?

Usage is only implied: the description notes there are no parameters and no paging, so an agent can infer this is a one-shot bulk fetch. It gives no explicit when-to-use condition or pointer to the alternatives (live_search, trending_effects) that an agent would need to choose correctly.

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