Session Cleanup

Backup old AMCP sessions by renaming with execution date, then clean and compact sessions and memory to keep the system efficient.

What to Clean

Session files backup: Rename session JSON files in ~/.config/amcp/sessions/ that haven't been modified in 30+ days to YYYY-MM-DD_<original_name>.json.bak
Active sessions keep: Keep the most recent 10 session files (by modification time) as active
Memory compaction: Compact ~/.config/amcp/memory/HISTORY.md to keep only the last 50 entries

Procedure

Step 1: Backup Old Sessions

List all .json files in ~/.config/amcp/sessions/ directory
Get modification time of each file
Sort by modification time (oldest first)
Keep the 10 most recent files as active
For files older than 30 days (or beyond the 10 most recent):
- Rename to YYYY-MM-DD_<original_name>.json.bak where YYYY-MM-DD is the current execution date
- Move to a backups/ subdirectory within sessions folder

Step 2: Clean Backup Files

Remove .bak backup files older than 90 days to free space
Report: "Backed up N session files, cleaned M old backups, freed X MB"

Step 3: Compact Memory

Read ~/.config/amcp/memory/HISTORY.md
Count the number of entries (each - bullet is an entry)
If more than 50 entries, keep only the last 50 entries
Add a summary entry at the top: "Compacted from X entries to 50 entries on YYYY-MM-DD"

Safety

Never delete the currently active session (most recent)
Only delete .json and .bak files (not directories or other file types)
Always create backups before any cleanup operation
Log each operation for audit trail

Example Output

Session Cleanup Report (2026-02-16):
- Active sessions kept: 10
- Sessions backed up: 15
- Old backups removed: 3
- Space freed: 45 MB
- Memory entries: compacted from 120 to 50
