xberg-typescript-toolchain is a skill for Claude Code, Codex from xberg-io/xberg. It costs 60 tokens per session (403 once invoked), scanned A, original, MIT.

A repository-specific guide for changing Xberg's TypeScript and JavaScript packages, including their testing, formatting, workspace, and native or WebAssembly boundaries.

In plain words
What is it for?
Use it when modifying Xberg TypeScript or JavaScript code, running its checks, changing integrations, or working with Node and WebAssembly bindings.
Why use it?
It prevents common tooling mistakes, such as using the wrong formatter, changing the wrong lockfile, or assuming packages share the same build setup.

About the project

Xberg is a document-intelligence engine that reads files, URLs, archives, and source trees and extracts text, metadata, images, tables, and structured data, with additional code-language understanding. Developers use it through language bindings, a command-line tool, REST API, or MCP server, and the catalogue entries support those integrations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

xberg-typescript-toolchain scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Xberg TypeScript toolchain

These repository-specific facts override generic TypeScript conventions where they differ.

  • Lint and format with poly lint . and poly fmt .. Poly embeds oxlint and oxfmt; do not install or invoke oxlint, oxfmt, Prettier, ESLint, or Biome directly, and do not add per-package lint scripts.
  • Root tsconfig.json enables strict checking options and is a project-reference root for e2e/node and e2e/wasm. Confirm that the package being changed is included before treating a root typecheck as evidence.
  • Testing uses Vitest with @vitest/coverage-v8. No coverage threshold is enforced unless one is added to current configuration.
  • No runtime schema-validator dependency is guaranteed. Use existing boundary guards or propose a dependency explicitly rather than assuming Zod is available.
  • The pnpm workspace uses the root lockfile. Packages under integrations/node/ are outside that workspace and use their own npm lockfiles. Determine ownership before installing or updating dependencies.
  • integrations/node/{langchain,llamaindex}-xberg use tsup. The Node binding is built by napi-rs and the WASM binding by wasm-pack; do not add an application bundler to either binding.
  • Prefer workspace:* for new dependencies between packages that are actually in the pnpm workspace.
  • JavaScript dependency auditing is manual unless a current workflow says otherwise; do not claim an audit ran merely because Rust or poly checks passed.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
