Directory

All ADR files go in docs/decisions/.

Rules

1. New ADR: Determine the next sequence number by scanning existing files in docs/decisions/
2. Update ADR: When updating an existing ADR, preserve the sequence number and update the relevant sections
3. Supersede: When a new decision supersedes an old one, update the old ADR's status to "superseded" and link to the new one
4. Date: Always use today's date in YYYY-MM-DD format
5. Status: New ADRs default to "proposed" unless the decision is already implemented, then use "accepted"
6. Language: Write in the same language the user has been using in the session (Korean if Korean, English if English, etc.)

When Updating Existing ADRs

• Read the existing file first
• Only modify the sections that need updating
• Add a note in "More Information" about what changed and why
• If the status changes, update the frontmatter
