+# Skill Creator
+
+Create new skills for MimiClaw.
+
+## When to use
+When the user asks to create a new skill, teach the bot something, or add a new capability.
+
+## How to create a skill
+1. Choose a short, descriptive name (lowercase, hyphens ok)
+2. Write a SKILL.md file with this structure:
+   - `# Title` — clear name
+   - Brief description paragraph
+   - `## When to use` — trigger conditions
+   - `## How to use` — step-by-step instructions
+   - `## Example` — concrete example (optional but helpful)
+3. Save to `/spiffs/skills/<name>.md` using write_file
+4. The skill will be automatically available after the next conversation
+
+## Best practices
+- Keep skills concise — the context window is limited
+- Focus on WHAT to do, not HOW (the agent is smart)
+- Include specific tool calls the agent should use
+- Test by asking the agent to use the new skill
+
+## Example
+To create a "translate" skill:
+write_file path="/spiffs/skills/translate.md" content="# Translate\n\nTranslate text between languages.\n\n## When to use\nWhen the user asks to translate text.\n\n## How to use\n1. Identify source and target languages\n2. Translate directly using your language knowledge\n3. For specialized terms, use web_search to verify\n"
