search_tiktok_videos

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

Discloses pagination behavior (cursor, has_more), sorting/filtering support, and that output is JSON with specific fields. No annotations present; description carries burden well. Lacks mention of authentication or rate limits, but these are common for search tools.

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?

Three sentences, front-loaded with purpose, then core features, then pagination detail. Highly efficient, no redundant words.

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?

Covers key behaviors: output format, result fields, sorting, filtering, pagination. Lacks error handling or rate limit info, but for a search tool with no output schema, it is largely sufficient.

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?

All 5 parameters have descriptions in schema (100% coverage). Description adds value by explaining pagination flow ('Use data.cursor...') and summarizing result contents beyond schema. Baseline 3, plus extra informativeness.

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?

Description clearly states verb 'Search', resource 'TikTok videos', and specifies output format 'as JSON' with result fields. Distinguishes from siblings like 'get_tiktok_video' (single video) and 'search_tiktok_users' (users).

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?

Provides clear context for when to use (searching videos by keyword) and pagination instructions, but does not explicitly mention when not to use or compare to alternative sibling tools like 'get_tiktok_hashtag_videos'.

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