What it does
Vbook Extensions is an agent skill from Darkrai9x/vbook-extensions. Create, fix, test, audit, refactor, build, or install vBook extensions against the current engine API and ScriptExecutor runtime. Use for extension source, plugin.json, vBook REST testing, packaging, or installation.
Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 81 other files, including scripts (for example `modes/audit.md`, `modes/create.md` and `modes/fix.md`).
It sits in Agent Workflows, covering Hooks and plugins and Refactoring.
When your agent uses it
- Extension source
- VBook REST testing
Example prompts
- “/vbook-extensions”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 24fe497. 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
Ships 2 files in scripts/ (JavaScript, from the files we listed), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Vbook Extensions loads about 817 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 348 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 348 words (~817 tokens).
“Canonical, vendor-neutral skill for this repository. Resolve every linked path relative to this file. .claude/skills/vbook-extensions/SKILL.md is only a compatibility pointer; never duplicate this skill there.”
