Initialize changelog

GOAL: create CHANGELOG.md and initialize commit pointer.

WHEN: the agent needs to start changelog management.

NOTE: exits gracefully if CHANGELOG.md already exists.

Efficiency directives

• Optimize all operations for token and context efficiency
• Batch operations on file groups, avoid individual file processing
• Target only relevant files
• Reduce token usage

Workflow

• Run scripts/init-changelog.sh
• Capture status from first line of output
• Handle the status:
  • If ERROR: Stop and report to user
  • If WARN: Report already exists
  • If SUCCESS: Report success
• DONE

Output

Files created:

• CHANGELOG.md - Main changelog file
• .last-aggregated-commit - Pointer file

Status communication:

First line of output indicates status:

• SUCCESS: [message] - Operation completed
• WARN: [message] - No changes made
• ERROR: [message] - Operation failed
