Skills

Skills are markdown-based extensions that live in ~/.mercury/skills/<name>/SKILL.md.

Default skills​

On first run, Mercury seeds a built-in web-search skill at:

~/.mercury/skills/web-search/SKILL.md

If you already have your own web-search skill, Mercury does not overwrite it.

Installing​

Tell Mercury in conversation:

Invoking​

  • "Use the daily-digest skill"

Scheduling a skill​

  • "Remind me daily at 9am to run the daily-digest skill"

Skills follow the Agent Skills specification. They get elevated permissions via allowed-tools and are loaded with progressive disclosure to save tokens.
