57 skills that make your AI an expert
Éclair skills turn Claude, Codex or ChatGPT into a developer who knows Éclair 2.0 inside out. You describe what your site needs, a shop, an online school, a directory or a WordPress migration, and the AI follows precise rules: where to put the code, how to protect data, which tests to pass. Nothing is activated without you.

What is an Éclair skill?
A skill is a folder containing a SKILL.md file and its references. Coding assistants such as Claude Code or Codex read it when your request matches its description. The skill gives them the context they lack: Éclair 2.0’s architecture, the eclair-extension/1 extension contract, the permitted locations, the security invariants and the acceptance criteria.
A manual for the AI
Diagnosis, procedure, deliverables and acceptance criteria, written for an agent.
Non-negotiable rules
Never touch the core, rights checked on every object, no private data in a shared cache.
Proof before going live
Package validation, full test suite, performance measurement and human review.
How it works, in 4 steps
- You install the skills your project needs, by family or one by one.
- You describe your need to your assistant: “a directory of craftspeople with filters by city”.
- The AI picks the relevant skills, reads your site’s real capabilities and prepares a design, the code in
site/extensions/orsite/themes/, and its tests. - You approve: the package passes the official validator, the tests and the performance check, then a person activates it from the admin.
The 57 skills, family by family
Each skill carries an honest status. ✅ means it relies on capabilities already in Éclair 2.0. 🧭 means it guides the design, but part of the journey (customer accounts, payment, public writing) depends on core building blocks not yet open.

What can you build with Éclair 2.0 today?
The table below follows the capability matrix published with the library. It avoids bad surprises: a feature can only ship to production if the core provides its contract.
| Feature | Éclair 2.0 contract | What the skills let you do |
|---|---|---|
| Public pages, SEO and GEO | Yes | Build and audit fast, well-ranked pages |
| Custom themes and blocks | Yes | Create a theme or blocks that survive updates |
| Admin screens | Yes | Build protected admin modules |
| Scheduled tasks | Yes | Automate imports, reports or syncs |
| WordPress import and old URLs | Yes, native feature | Prepare and check a migration without losing URLs |
| Public sign-up and login | Not yet | Design, test, prepare the RFC |
| Cart, payment, orders | Not yet | Specifications and design tests, no production shop |
| Forum or LMS with writing | Not yet | Journeys, data and tests ready for when the core opens them |
How do you install the skills?
You need Python 3 and a copy of the library. Download it from GitHub, then, in its folder:
python3 scripts/validate_skills.py
python3 scripts/install_skills.py --list
python3 scripts/install_skills.py --project /path/to/my-site --category foundation
python3 scripts/install_skills.py --project /path/to/my-site --skill eclair-wordpress-migration
python3 scripts/install_skills.py --project /path/to/my-site --allSkills are copied into your project’s .agents/skills/ folder, the one Codex reads. For Claude Code, copy the folders you want into .claude/skills/. The installer never replaces an existing skill unless you add --force after review. The families are called foundation, commerce, lms, community, business, design, seo and integrations.
Create your own skills
The foundations family also serves as a model: a skill is a skills/eclair-<name>/ folder with a SKILL.md (name, description, procedure, acceptance criteria) and its references/. You can write your own for your trade, validate it with python3 scripts/validate_skills.py and propose it to the library. The whole method is in the article on the core and the skills.
Frequently asked questions about Éclair skills
Are the skills free?
Yes. The library is published under the AGPL-3.0 free software license, like Éclair CMS. Only your AI assistant may cost something, depending on your subscription.
Does a skill install a shop or a forum on its own?
No. A skill guides the agent: it produces a design, code and tests, which a person approves and activates. Commerce, learning and forum journeys still depend on core building blocks (public accounts, payment): they are not ready for production.
Which AI assistants can use the skills?
Those that read SKILL.md folders: Claude Code, Codex and other compatible agents. With a chat assistant such as ChatGPT, you can also give it the content of the relevant SKILL.md.
Do I need to know how to code?
Not to describe your need. You do need someone able to review what the agent proposes, run the tests and activate the feature knowingly.
Do the skills modify Éclair’s core?
Never. Everything they produce lives in site/extensions/ or site/themes/, which updates never touch. A missing core capability leads to an RFC, not a workaround.
Can I create my own skills?
Yes: a folder, a SKILL.md, references and the library’s check scripts. The guide and the article explain the method.
