Add Config Field

Add a new field to the .agents.yml config schema with proper versioning and migration support.

Files Changed

| File | Purpose | |------|---------| | plugins/majestic-engineer/commands/workflows/init.md | 4 YAML templates that generate .agents.yml | | plugins/majestic-engineer/config-schema-version | Schema version number | | plugins/majestic-engineer/agents/config-reader.md | Changelog + migration logic | | plugins/majestic-engineer/.claude-plugin/plugin.json | Plugin version | | .claude-plugin/marketplace.json | Marketplace version |

Input

  • Field name: e.g., auto_commit
  • Default value: e.g., false or multi-line YAML
  • Section: Where in template (Workflow, Quality Gate, etc.)
  • Comment: Inline explanation
  • Used by: Agent/command that reads this field

Steps

1. Update init.md Templates

File: plugins/majestic-engineer/commands/workflows/init.md

Add field to ALL 4 templates (Rails, Python, Node, Generic). Find the appropriate section and add:

new_field: value              # Comment explaining purpose

Or for multi-line:

new_field:                    # Comment
  - item1
  - item2

2. Bump Schema Version

File: plugins/majestic-engineer/config-schema-version

Increment: 1.1 → 1.2

3. Update config-reader.md

File: plugins/majestic-engineer/agents/config-reader.md

A) Add to Version Changelog table:

| 1.2 | `new_field` | Description |

B) Update migration YAML block (in "Outdated config_version" section):

new_field: default_value

4. Bump Plugin Versions

Files:

  • plugins/majestic-engineer/.claude-plugin/plugin.json: 3.15.0 → 3.16.0
  • .claude-plugin/marketplace.json: Update majestic-engineer entry version

5. Update Consumer Docs (if needed)

If a specific agent/command reads this field, update its documentation to mention the config.
