merge_m3u8_to_mp4

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

No annotations provided. Description only lists parameters and fails to disclose important behavioral traits such as network dependency, potential duration, or error conditions. Does not warn about potential side effects (e.g., file creation).

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?

Extremely concise: one-line summary followed by clean Args section. No redundant sentences. Every piece of text contributes value.

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?

Despite a moderate number of sibling tools, the description lacks details about return format, error handling, or operation duration. Given the tool's complexity (streaming conversion), the description is too minimal to fully inform an AI agent.

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?

With 0% schema description coverage, the description effectively compensates by explaining each parameter: m3u8_url as 'M3U8 playlist URL', output_path as 'Output MP4 file path', headers with format hint. This adds meaning beyond the schema's type definitions.

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 '合并M3U8流为MP4文件' (merge M3U8 stream to MP4 file), giving a specific verb and resource. It distinguishes from sibling tools like merge_audios or merge_videos by targeting M3U8 streams.

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 (e.g., convert_video_format for local files). No mention of prerequisites like network access or typical use cases.

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