Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

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 Eventually your boot-up reads 50K tokens of memory and half of it is outdated.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.

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 Stats: Overview of memory file sizes and growth rates

Category context

Agent frameworks, memory systems, reasoning layers, and model-native orchestration.
