Dev Skill Pack·Free, for Windows, macOS and Linux

Give your coding agent seven new skills

One command installs the skills we use every day to build software, and your agent picks them up on its own: Claude Code, Codex, Cursor, Gemini CLI, and OpenCode. It also stops your agent writing like a chatbot, in every reply, without being asked.

$ curl -fsSL https://eligapris.com/skills.sh | sh

Paste it in a terminal. Read the installer first

Or download the zip

How it works

Three steps. The first one is the only one you do.

  1. 1

    Paste the line

    It copies seven skills into ~/.agents/skills in a few seconds, for your user only.

  2. 2

    It finds your agents

    Each skill is linked into every agent on your computer, and the writing rule goes into their global instructions so it's always on.

  3. 3

    Open a new session

    Ask for what you need. The agent loads the right skill by itself, or call one by name, like /draft.

Why use it

What's in the pack

dev

Takes an app toward production quality: design, missing features, performance, and the edge cases users hit first.

draft

Reads your staged changes and writes a short, clear commit message you can use as is.

research-lab-feature

For algorithm and performance problems that off-the-shelf code can't solve. It works from published research, not guesses.

software-architect

Reviews structure, records each decision, and keeps the codebase on one approach for data, logic, and integrations.

agent-led-product

Scores a project and converts it into something AI agents can run: an MCP server, scoped API keys, a CLI, and agent docs.

first-principles

Breaks a problem down to what's actually true and builds the solution up from there, instead of copying the usual answer.

humanize

Always on: your agent stops writing like a chatbot. No em dashes, no "delve", no "I hope this helps". It comes with a checker that flags what slipped through.

Nothing of yours is overwritten

If you already have a skill with the same name, the old copy is moved to ~/.agents/skill-backups first. Instruction files are backed up there before the writing rule is added.

Plain text files, nothing sent anywhere

Skills are instructions and a few helper scripts that sit in a folder on your computer. The installer downloads one zip from eligapris.com, adds the writing rule to your agents' instruction files, and sends back one anonymous install report (pack, version, OS, which agents it set up) so we can count installs. Run it with DO_NOT_TRACK=1 to skip that. You can read it before you run it.

FAQ

Questions people ask

What is an agent skill?+

A folder with a SKILL.md file that tells an AI coding agent how to do one kind of job well. The agent reads the short description, and loads the full instructions only when your request needs them.

How do I install it?+

On macOS or Linux, open a terminal and paste curl -fsSL https://eligapris.com/skills.sh | sh. On Windows, open PowerShell and paste irm https://eligapris.com/skills.ps1 | iex. Then start a new session in your agent.

Can my AI agent install it for me?+

Yes. Paste this into your agent: "Set up the skill pack from https://eligapris.com/skills.md". The page at eligapris.com/skills.md tells the agent what to run for your system, how to check it worked, and to follow the writing rule for the rest of that conversation.

Which agents does it work with?+

Claude Code, OpenAI Codex, Cursor, Gemini CLI, and OpenCode. The installer links the skills into whichever of them it finds. Any other agent that reads ~/.agents/skills picks them up too.

How does the writing rule work without me calling a skill?+

Agents read a global instructions file at the start of every session. The installer adds the humanize rules there: ~/.claude/CLAUDE.md for Claude Code, ~/.codex/AGENTS.md for Codex, ~/.gemini/GEMINI.md for Gemini CLI and ~/.config/opencode/AGENTS.md for OpenCode. Cursor keeps its global rules in its settings, so there you get the humanize skill but not the always-on rule.

Can I turn the writing rule off?+

Yes. Open the instructions file and delete everything between the dev-skill-pack:humanize start and end markers. Running the installer again adds it back; it never adds it twice.

Does it need admin rights?+

No. Everything goes into your own home folder. On Windows the links are directory junctions, which don't need admin rights.

Will it replace skills I already have?+

Only ones with the same name, and those are moved to ~/.agents/skill-backups/<date> first, never deleted. Running the installer again just updates the pack.

Is it safe to run?+

The installer only copies folders and makes links inside your home folder. You can read it first at eligapris.com/skills.sh or eligapris.com/skills.ps1.

What does the installer send back?+

One anonymous report when it finishes: which pack and version, your OS and processor type, which agents it set up, and whether it was the one-line or zip install. No paths, usernames, file contents or anything from your projects. The install counts on this page come from those reports. To skip it, put DO_NOT_TRACK=1 in front of sh, for example curl -fsSL ... | DO_NOT_TRACK=1 sh, or set it in PowerShell with $env:DO_NOT_TRACK=1 first.

How do I update or remove it?+

Run the same line again to update. To remove it, delete the seven folders from ~/.agents/skills (the links in your agents' skills folders can go too) and delete the dev-skill-pack:humanize block from your agents' instruction files.
