Session Memory 🧠 v2.0

Persistent memory for AI agents. Save what matters, recall what's relevant, consolidate what you've learned.

v2.0: relevance-scored search, importance levels, session context loader, consolidation, export/import, stats, edit/delete.

Quick Start

# Save a memory (with optional importance)
MEMORY_IMPORTANCE=high ./scripts/save.sh "decision" "Chose Postgres over SQLite for scale"

# Recall with relevance scoring
./scripts/recall.sh "database" --limit 5

# Load session context (startup)
./scripts/context.sh --days 3

# Consolidate by topic
./scripts/consolidate.sh --since 2026-01-01

# Stats
./scripts/stats.sh

Commands

save.sh — Save a Memory

./scripts/save.sh "topic" "content" [tags...]

Env	Default	Description
AGENT_MEMORY_DIR	~/.agent-memory	Storage directory
MEMORY_IMPORTANCE	normal	low / normal / high / critical

# Basic save
./scripts/save.sh "insight" "Users prefer dark mode 3:1" ui design

# High importance
MEMORY_IMPORTANCE=high ./scripts/save.sh "decision" "Migrated to TypeScript" refactor

# Critical (always surfaces in context.sh)
MEMORY_IMPORTANCE=critical ./scripts/save.sh "credential" "API key rotated, new one in vault"

recall.sh — Search Memories

./scripts/recall.sh "query" [--json] [--limit N] [--topic T] [--importance I] [--since YYYY-MM-DD]

Features:

• Multi-keyword AND search — all words must match
• Relevance scoring — based on word match ratio + importance + recency
• Filters — by topic, importance level, date range

./scripts/recall.sh "database migration"
./scripts/recall.sh "API" --topic decision --limit 20
./scripts/recall.sh "deploy" --since 2026-03-01 --json
./scripts/recall.sh "error" --importance high

context.sh — Session Startup Loader

./scripts/context.sh [--days N] [--limit N] [--json]

Loads the most relevant memories for a new session:

• Recent memories (last N days, default 3)
• High/critical importance items regardless of age
• Sorted by importance then recency
• Grouped by date

# Quick context
./scripts/context.sh

# Wider window
./scripts/context.sh --days 7 --limit 30

# For programmatic use
./scripts/context.sh --json

daily.sh — Day View

./scripts/daily.sh [YYYY-MM-DD] [--json]

topics.sh — Topic Index

./scripts/topics.sh [--json]

consolidate.sh — Topic Consolidation

./scripts/consolidate.sh [--since YYYY-MM-DD] [--topic T] [--json]

Groups all memories by topic, showing counts, date ranges, top tags, and latest entries. Useful for periodic review.

stats.sh — Memory Statistics

./scripts/stats.sh [--json]

Shows: total entries, date range, entries/day average, storage size, topic breakdown, importance distribution.

edit.sh — Edit or Delete

./scripts/edit.sh <timestamp_ms> --content "new content"
./scripts/edit.sh <timestamp_ms> --topic "new topic"
./scripts/edit.sh <timestamp_ms> --importance critical
./scripts/edit.sh <timestamp_ms> --delete

export.sh — Export Memories

./scripts/export.sh [-o backup.json] [--since YYYY-MM-DD] [--topic T]

import.sh — Import Memories

./scripts/import.sh backup.json [--dry-run]

Deduplicates by timestamp — safe to run multiple times.

prune.sh — Archive Old Memories

./scripts/prune.sh [days]

Moves memories older than N days (default: 30) to archive/.

Each line is a JSON object:

{"ts":1706793600000,"topic":"decision","content":"Chose X because Y","tags":["project"],"importance":"high"}

Importance Levels

Level	When to Use	Behavior
low	Background info, minor notes	Only found via search
normal	Standard memories	Shown in daily view
high	Key decisions, insights	Always in session context
critical	Credentials, blockers, urgent	Always in session context, top priority

Recommended Workflow

# Session start
./scripts/context.sh

# During work — save important things
./scripts/save.sh "decision" "..."
MEMORY_IMPORTANCE=high ./scripts/save.sh "insight" "..."

# End of session
./scripts/save.sh "summary" "Today: did X, decided Y, next step Z"

# Weekly review
./scripts/consolidate.sh --since $(date -u -d '7 days ago' +%Y-%m-%d)
./scripts/stats.sh

# Monthly maintenance
./scripts/prune.sh 60
./scripts/export.sh -o backup-$(date +%Y%m).json
