Changelog Observer

Changelog Observer

Track session context in .changelog/session-YYYY-MM-DD.md.

Log target

• Use .changelog/session-YYYY-MM-DD.md for the current local date.
• Create .changelog/ and the session file if they do not exist.
• If the session file is new, initialize it from template.md.
• Append new entries in chronological order.

What to log

• file-change: after creating, editing, or deleting project files.
• test-result: after running tests, checks, or validation commands.
• decision: after making an implementation or architecture decision worth preserving.

Entry rules

• Keep each description short and specific.
• List only directly affected files.
• Use none when no files were changed.
• Do not rewrite earlier entries unless they are incorrect.

Template

Use the markdown structure in template.md for each appended entry.
