+# AGENTS.md
+
+Guidance for AI coding agents working in this repository.
+
+## What this repository is
+
+A collection of skills for AI coding agents working with the Pro Cycling Manager game. Skills are packaged instructions and scripts that extend agent capabilities.
+
+## Creating a New Skill
+
+Skills follow the [Agent Skills](https://agentskills.io/) format, so they work with any agent that reads it.
+
+Prefer the `/skill-creator:skill-creator` skill (if available in your agent environment, otherwise skip this step) to create a new skill (or to edit and
+improve an existing one). It walks through capturing intent, drafting `SKILL.md`, running
+test prompts, and optimizing the description for reliable triggering. Then apply the
+repository conventions below to the result.
+
