what is codex-skill-builder fr?

codex-skill-builder is a Codex skill that turns a repeated workflow, a piece of documentation, or a checklist into a Codex skill that Codex itself can run reliably. The README frames it as more than writing a longer prompt: the real work is deciding when the skill should trigger, giving it a workflow structure, storing knowledge in files instead of relying on the model to remember, defining safety boundaries, and producing something verifiable before it ships. The tool works in three steps. Need Snapshot asks a small number of key questions up front, rather than an open-ended interview, to pin down the inputs, outputs, restrictions, and success criteria. Skill Blueprint then breaks the idea into the pieces a skill needs, such as a SKILL.md file, reference material, scripts, and examples. Validate and Ship generates a preview version, checks its structure, and prepares it for release without touching the user's global skill folder until it is ready. The README also lists planned follow-ups such as reviewing an existing skill, converting README or API documentation into a skill, and packaging a finished skill for distribution. A finished skill is meant to answer five questions: when it should trigger, what input the user will give, what steps Codex should follow, what knowledge belongs in files rather than context, and which actions need confirmation first. The generated skill folder follows a fixed layout, with SKILL.md holding the main flow and trigger logic, a references folder for longer rules and methodology, a scripts folder for deterministic repeatable actions, and an examples folder with real trigger phrases and before and after cases. A Python script, quick_validate.py, checks the folder's structure before publishing. The project is installed by adding its skills/codex-skill-builder folder to Codex and restarting it, and is released under the MIT License.
