hr-skills: Skill for Claude Code

.agents/skills/biome/SKILL.md

biome is a skill for Claude Code, Codex from tuanductran/hr-skills. It costs 29 tokens per session (949 once invoked), scanned A, original, MIT.

Repository guidance for Biome, a tool that formats code, checks for common problems, and organizes imports. In this repository it is used for TypeScript, JSON, JSONC, and YAML files.

In plain words
What is it for?
Use it to format files, lint code, organize imports, apply safe fixes, validate repository formatting, and troubleshoot the shared Biome configuration.
Why use it?
It keeps code style and quality checks consistent and explains how to resolve Biome diagnostics without guessing the repository's conventions.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is tuanductran/hr-skills's own configuration. It tells Claude Code and Codex how to work on hr-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything hr-skills configures →

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

biome 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 12d 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.

Biome

This skill describes how Biome is used throughout the hr-skills monorepo. It covers formatting, linting, import organization, repository conventions, and development workflows.

The repository standardizes on Biome as the primary code quality tool for TypeScript, JSON, JSONC, and YAML files.

Supported tasks

  • Explain how Biome is used within this repository
  • Format source code consistently
  • Review Biome diagnostics
  • Organize imports
  • Validate repository formatting
  • Apply safe code fixes
  • Explain repository formatting conventions
  • Troubleshoot Biome configuration issues
  • Generate repository-compatible Biome configuration

Repository conventions

This repository uses a single Biome configuration located at the repository root.

Biome is responsible for:

  • code formatting
  • linting
  • import organization
  • repository code consistency

Supported file types include:

  • TypeScript
  • JSON
  • JSONC
  • YAML

Repository-generated directories are excluded from analysis.

Formatting conventions

The repository follows these formatting conventions.

  • Tabs for indentation.
  • Indentation width of 4.
  • LF line endings.
  • Maximum line width of 90 characters.
  • Single quotes for JavaScript and TypeScript.
  • Semicolons are always required.
  • Trailing commas are enabled.
  • Parentheses are always used for arrow function parameters.
  • Imports are automatically organized.

These conventions are enforced automatically by Biome.

Linting

The repository enables the recommended Biome rule set, with one override: complexity/useLiteralKeys is turned off (see biome.jsonc).

Linting focuses on:

  • correctness
  • readability
  • maintainability
  • consistent code style

Compiler errors remain the responsibility of TypeScript.

Import organization

Biome automatically organizes imports.

The repository relies on automatic import ordering rather than manual sorting. Safe import organization is part of the Biome toolchain.

Common commands

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.

biome is a skill published in the GitHub repository tuanductran/hr-skills (57 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 949 once invoked, about $0.0001 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.
