What it does
Preview Build is an agent skill from Mr-Quin/danmaku-anywhere. Use when you need to load a specific published preview/nightly extension build into the agent's browser by run-number, branch name, or tag. Faster than rebuilding locally when you only want to exercise an existing artifact.
Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with PowerShell. The repository describes itself as: 一个可以给几乎任何视频网站添加弹幕的开源软件 | An open source solution to add danmaku to almost every video website.
When your agent uses it
- You need to load a specific published preview/nightly extension build into the agents browser by run-number
Example prompts
- “/preview-build”
Requirements
- Node.js
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Resolve the release
- Download + expand
- Load into the browser
- Tear down
What it can do on your machine
Read from SKILL.md and the folder at commit d2d6d41. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
ghnpxpnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use gh, npx and pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Preview Build loads about 886 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 276 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 276 words (~886 tokens).
“Resolve a GitHub release published by CI (nightly or branch-preview), download its Chrome zip, expand it to .tmp/, and load that directory instead of a local build. For exploring the build you just compiled, use browser-verify instead.”
