name: skill description: Create a new BSage Skill with standard boilerplate

Skill Command

Generate a new Skill with standard structure and boilerplate.

Usage

/skill <category>/<skill-name>

Example

/skill input/calendar-input
/skill process/garden-writer
/skill output/git-output
/skill meta/skill-builder

What This Does

1. Creates skill directory at skills/<skill-name>/
2. Generates skill.yaml with category-appropriate defaults
3. Generates skill.py with execute(context) boilerplate
4. Creates test file at bsage/tests/test_skill_<name>.py

Generated Structure

For /skill input/calendar-input:

skills/
└── calendar-input/
    ├── skill.yaml      # Metadata + trigger config
    └── skill.py         # execute(context) function

bsage/
└── tests/
    └── test_skill_calendar_input.py

Generated Files

skills/calendar-input/skill.yaml

name: calendar-input
version: 1.0.0
author: bslab
category: input
is_dangerous: false
entrypoint: skill.py::execute
trigger:
  type: cron

    # Skill 내부에서 직접 API 연결 처리
    events = await fetch_calendar_events(creds)

    await context.garden.write_seed("calendar", {"events": events})

    context.logger.info("calendar_input_complete", event_count=len(events))
    return {"collected": len(events)}

Next Steps

After generation:

1. Fill in skill.py implementation
2. Update skill.yaml fields (rules, trigger)
3. Add test cases for error paths
4. Run tests with /test
5. Verify Skill loads correctly with SkillLoader
