nx-biome-integration

nx-biome-integration is a skill for Claude Code, Codex from pantheon-org/tekhne. It costs 63 tokens per session (1,082 once invoked), scanned A, original, MIT.

A setup and migration guide for using Biome, a tool for checking and formatting code, across Nx monorepos. It covers replacing ESLint and Prettier and configuring workspace-wide tasks.

In plain words
What is it for?
Use it to install Biome, configure project targets, migrate from ESLint or Prettier, and validate checks across an Nx workspace.
Why use it?
It helps keep linting and formatting rules consistent while making Nx builds and checks cache-aware. It also provides a controlled path for migrating existing projects.

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

nx-biome-integration 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 9d 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.

Nx Biome Integration

Navigation hub for integrating Biome in Nx workspaces with predictable setup and migration.

When to Use

  • You need to add Biome lint and format targets in an Nx workspace.
  • You are migrating from ESLint or Prettier to Biome.
  • You need Nx cache-friendly Biome task configuration.
  • You are creating plugin-based inferred tasks for workspace scale.

Principles

  • Prefer one root config unless migration constraints require nested overrides.
  • Keep lint and format authority singular for each file path.
  • Optimize for deterministic CI (read-only checks) and reproducible local fixes.

When Not to Use

  • The repository standard is intentionally ESLint/Prettier-only.
  • The task is not Nx-related and does not require workspace task integration.

Workflow

  1. Confirm prerequisites: Nx workspace, Node.js 18+, package manager selected.
  2. Install Biome and initialize root configuration.
  3. Add project targets (or plugin inferred tasks) and enable Nx caching inputs.
  4. Validate lint and format execution on one project, then run across workspace.
  5. Apply migration strategy (all-at-once or selective nested biome.json).
  6. Enforce anti-pattern checks before rollout.

Quick Commands

Install and Initialize

npm install --save-dev @biomejs/biome
npx @biomejs/biome init

Expected: root biome.json exists.

Run on One Project

nx biome-lint my-project
nx biome-format my-project

Expected: lint and format targets execute for the selected project.

Run Across Workspace

nx run-many -t biome-lint
nx run-many -t biome-format

Expected: all configured projects run with consistent config and cache behavior.

Run Through Package Script

bun run nx run-many -t biome-lint

Expected: Biome lint runs through package-managed Nx entrypoint.

Reset Nx State After Plugin Changes

nx reset

Expected: daemon cache is cleared and targets refresh.

Anti-Patterns

NEVER use nested biome.json for simple workspace-wide setups

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.

nx-biome-integration is a skill published in the GitHub repository pantheon-org/tekhne (10 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 1,082 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 2026-09-03.
