tiktok_mobile_feed_post

Read-only

Fetch TikTok's primary protobuf feed and return a schema-free field-number decode. Use tiktok_mobile_feed for the stable structured feed contract.

Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds important behavioral context by warning that the result is a schema-free field-number decode, which is essential for interpreting the output, though it does not discuss response size, pagination, or rate behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with the action and output shape, followed by the sibling-tool routing guidance. Every phrase carries useful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-argument, read-only feed tool with annotations and an output schema, the description provides enough context to invoke it correctly and understand the special raw-decode return format. No critical invocation detail is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters and 100% schema description coverage, so parameter semantics are inherently minimal. The description correctly does not waste space explaining inputs that do not exist.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb (Fetch) and resource (TikTok's primary protobuf feed), and explicitly states the unusual return form: a schema-free field-number decode. It also directly distinguishes this tool from tiktok_mobile_feed, so an agent can tell why this variant exists.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It names the sibling tool explicitly and gives the condition for choosing it: tiktok_mobile_feed is for the stable structured feed contract. That contrast clearly routes the agent to this tool when raw protobuf field-number decoding is needed.

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