hr-skills: Skill for Claude Code

.agents/skills/bun/SKILL.md

bun is a skill for Claude Code, Codex from tuanductran/hr-skills. It costs 27 tokens per session (1,543 once invoked), scanned A, original, MIT.

A repository guide for using Bun, a JavaScript runtime and package manager, in the hr-skills monorepo. A monorepo is one code repository that contains multiple related packages.

In plain words
What is it for?
Use it to manage workspace dependencies, run TypeScript and tests, build packages, validate repository metadata, and troubleshoot Bun workspace issues. It also explains when to use Bun-specific features instead of Node.js APIs.
Why use it?
It gives the repository one standard way to install dependencies, run scripts, build packages, test code, and check types. This avoids inconsistent workflows across developers and automated checks.

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 →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

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

bun 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.

Bun

This skill explains how Bun is used throughout the hr-skills monorepo. It covers workspace management, development workflows, validation commands, testing, and repository conventions.

The repository standardizes on Bun for all package management and script execution. Turborepo orchestrates tasks across workspace packages.

Supported tasks

  • Explain how Bun is used within this repository
  • Install and manage workspace dependencies
  • Run repository scripts using Bun
  • Validate HR skills and repository metadata
  • Synchronize generated repository artifacts
  • Build workspace packages
  • Run tests and TypeScript type checking
  • Troubleshoot Bun workspace issues
  • Recommend Bun workflows for local development and CI
  • Explain Bun compatibility with Node.js
  • Recommend Bun-native APIs when appropriate
  • Explain when to use Bun-specific features versus Node.js APIs

Repository usage

This repository uses Bun for:

  • package management
  • workspace dependency resolution
  • script execution
  • TypeScript execution
  • test execution

Package managers such as npm, pnpm, and Yarn are not supported.

Dependency catalogs

This repository centralizes shared dependency versions using Bun catalogs.

Catalogs ensure that common dependencies are defined once in the root package.json and reused consistently across every workspace package.

Workspace packages should reference shared dependencies using the catalog: protocol instead of repeating version numbers.

Use the default catalog.

{
  "dependencies": {
    "typescript": "catalog:"
  }
}

Use a named catalog.

{
  "devDependencies": {
    "@biomejs/biome": "catalog:biome",
    "@commitlint/cli": "catalog:commit"
  }
}

Benefits:

  • keeps dependency versions consistent across the repository
  • updates shared dependency versions in one place
  • reduces duplicated version declarations
  • simplifies workspace maintenance

Internal workspace packages should continue using the workspace:* protocol.

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.
