AC douyin-dl
Download Douyin (抖音) videos via the TikHub API — no login required. USE THIS SKILL whenever the user: - Shares a Douyin link (v.douyin.com, douyin.com, or any URL containing "douyin") - Pastes a modal_id or aweme_id (16–19 digit number) - Says "下载视频", "帮我下载", "save this video", "download this douyin" - Shares a short-link like "复制链接" text containing v.douyin.com - Asks to save, grab, or fetch a Douyin clip Always use this skill when you detect a Douyin URL or a numeric video ID — even if the user doesn't explicitly say "download". Just seeing a v.douyin.com link is enough. DO NOT USE FOR: - YouTube, Bilibili, Instagram, or other platforms (use their respective tools) - Douyin live streams (not supported by the API) - Douyin image carousels / 图集 (video-only)
As a process C 59/100 · Has gaps — weak spots: inputs and preconditions, failures and branches, consistency
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 59/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 40Consistency. Frontmatter name (douyin-dl) differs from the folder (grab-douyin)
- 60Tools and files. Uses tools (python) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 100Steps. 5 steps
- 100When it triggers. States when to use and when not to
- 100Execution cost. Instruction body is 405 tokens
- 100Running it twice. No mutating operations
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
