name: observational-memory description: > Two-tier compressed memory system using Observer and Reflector background agents. Replaces raw conversation history with dense, prioritized observations and long-term reflections.

Observational Memory — Skill Guide

Overview

Two background agents maintain compressed memory files that your main agent reads on startup:

memory/observations.md — Timestamped, prioritized notes from recent conversations (updated every 15 min)
memory/reflections.md — Condensed long-term memory: identity, projects, preferences (updated daily)

Installation

git clone https://github.com/intertwine/observational-memory.git
cd observational-memory
bash scripts/install.sh

Or manually: copy the prompts from reference/ into your skills directory and create cron jobs per the instructions below.

AGENTS.md Integration

Add to your "Every Session" context loading:

## Every Session
...
5. Read `memory/observations.md` — recent compressed observations (auto-maintained by Observer)
6. Read `memory/reflections.md` — long-term condensed memory (auto-maintained by Reflector)

Cron Jobs

The install script creates two cron jobs:

Job	Schedule	Prompt	Purpose
`observer-memory`	`/15 * * *`	`observer-prompt.md`	Compress recent messages → observations
`reflector-memory`	`0 4 * * *`	`reflector-prompt.md`	Incrementally update reflections from new observations

Configuration

Model

Default: anthropic/claude-sonnet-4-20250514. Override during install:

bash scripts/install.sh --model anthropic/claude-opus-4-6

Frequency

Observer: --observer-interval "*/30 * * * *" (default: every 15 min)
Reflector: --reflector-schedule "0 6 * * *" (default: daily at 04:00 UTC)

Manual Triggers

openclaw cron trigger observer-memory
openclaw cron trigger reflector-memory

Tuning

Observer threshold: Skips runs with fewer than ~10 new messages (configurable in prompt)
Reflector target: Aims for 200–600 lines in reflections.md (configurable in prompt)
Reflector incremental: Only processes observations since Last reflected timestamp; chunks large inputs automatically
Observation retention: 7 days before the reflector trims old entries

Edit the prompts in reference/ to adjust priority definitions, compression rules, or output format.

Enhanced Search with QMD (Optional)

QMD adds hybrid search (BM25 + vectors + reranking) over your compressed memory files, making it easy to recall specific observations from weeks or months ago.

bash scripts/enable-qmd.sh           # Enable QMD backend
bash scripts/enable-qmd.sh --disable # Revert to default

QMD is optional — OM works great standalone. If QMD is unavailable, OpenClaw falls back to built-in vector search. See the README section on QMD for architecture details and resource requirements.

Relationship to MEMORY.md

Options:

Replace MEMORY.md — let observations + reflections be your entire memory system
Supplement — keep MEMORY.md for manually curated notes alongside auto-generated memory

Option 1 is recommended for most setups.
