abdm_download_hls

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

The description discloses meaningful behavior beyond the annotations: mode-specific GUI triggering, silent background download, and the sandboxed-folder constraint. It does not mention status polling, error behavior, or output location, but the disclosed side effects are valuable for an agent deciding whether to invoke this tool.

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?

The description is compact and front-loaded with the core purpose, and both sentences contribute useful information. It loses a point for vague phrasing like 'allowed sandboxed folder' and 'streaming video/audio task', which could be more concrete, but it is not bloated or redundant.

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 10 parameters and zero schema-level parameter descriptions, the description covers only purpose and mode behavior. It omits guidance on how parameters like filename, queue_id, speed_limit_bytes, or download_page affect the download, making the tool under-specified for correct invocation in varied use cases.

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 schema description coverage is 0%, so the description must compensate for parameter meaning. It explains the 'mode' enum distinction, but the other nine parameters (url, headers, filename, queue_id, category_id, start_queue, subdirectory, download_page, speed_limit_bytes) are left entirely undocumented in both the schema and description.

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?

The description states a specific verb ('Download') and resource ('HLS (.m3u8) streaming video/audio task'), and adds the distinguishing detail 'with segment reassembly'. This clearly differentiates the tool from generic siblings like abdm_download and abdm_download_batch.

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?

The description gives clear mode-based context: interactive triggers a desktop GUI and headless starts a silent background download. However, it does not explicitly state when to prefer this tool over sibling tools such as abdm_download or abdm_download_batch, leaving some inference to the agent.

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