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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.00403 |
| Opus 5 | $0.00030 | $0.00201 |
| Sonnet 5 | $0.00012 | $0.00081 |
| Haiku 4.5 | $0.00006 | $0.00040 |
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 .andpoly 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.jsonenables strict checking options and is a project-reference root fore2e/nodeande2e/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}-xberguse 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.
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.

xberg-typescript-toolchain is a skill published in the GitHub repository xberg-io/xberg (9,281 stars, last pushed today), licensed MIT. It adds 60 tokens to every session and 403 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
