Memory Pruner

核心功能：支持按行修剪文件、日志目录循环缓存保留最新文件、按日期压缩状态文件、设置大小限制，提供预览及内存统计。典型场景：解决代理内存文件、日志无限增长，导致启动加载过时内容、磁盘不足问题。输入为带参数的Python命令，输出为处理后的文件或预览、统计结果。

Memory Pruner

Keep your agent's memory lean. Automatically prune logs, compact state files, and enforce size limits so your agent never runs out of disk or context window.

Why This Exists

Agents accumulate memory files over time. Logs grow unbounded. State files collect stale entries. Eventually your boot-up reads 50K tokens of memory and half of it is outdated. Memory Pruner enforces limits and keeps only what matters.

Commands

Prune a memory file (keep last N lines)

python3 {baseDir}/scripts/memory_pruner.py prune --file ~/wake-state.md --max-lines 200

Prune a log directory (circular buffer, keep last N files)

python3 {baseDir}/scripts/memory_pruner.py prune-logs --dir ~/agents/logs/ --keep 7

Compact a state file (remove sections matching a pattern)

python3 {baseDir}/scripts/memory_pruner.py compact --file ~/wake-state.md --remove-before "2026-02-14"

Check memory sizes

python3 {baseDir}/scripts/memory_pruner.py stats --dir ~/

Dry run (show what would be pruned)

python3 {baseDir}/scripts/memory_pruner.py prune --file ~/wake-state.md --max-lines 200 --dry-run

Features

Line-based pruning: Keep last N lines of any file
Log rotation: Circular buffer for log directories (keep last N files, delete oldest)
Date-based compaction: Remove entries older than a cutoff date
Size limits: Enforce max file sizes in bytes
Dry run mode: Preview changes before applying
