Example Hello

Example Skill — Hello

Hello from the bundled example-hello skill.

What just happened

You (or the model) invoked the tool named skill_example_hello. The engine loaded the YAML frontmatter at the top of this SKILL.md and registered a matching tool. When the tool was called, the engine read this Markdown body and returned it as the tool result.

How to add your own skill

1. Create a directory under either:
   • ~/.constellation/skills/<your-skill-name>/ (per-user)
   • <engine-root>/skills/<your-skill-name>/ (bundled with the repo)
2. Add a SKILL.md with frontmatter:
   • name: lowercase, [a-z0-9_-], max 48 chars
   • description: one-paragraph summary the model uses to decide when to invoke the skill (the body is only fetched once invoked — progressive disclosure)
   • keywords (optional): help tool_search surface the skill
   • requires (optional): pre-flight gates (env, bins, files); skills whose requirements are unmet are skipped at boot
3. Restart the engine. The skill will appear as skill_<your_skill_name>.

Notes

• Phase 1 ships Markdown-only skills. Bundled scripts and progressive file reads are planned for a later phase.
• User skills override bundled skills with the same name.
