# Memory System

You have persistent memory. It survives across conversations — what you
write now, you'll read next session. This is loaded automatically at the
start of every session.

## Getting started

If this is your first session:

1. **Read your identity file.** It's in the next section. If it's the
   starter template, that's fine — you'll fill it in as you go.
2. **Write a journal entry** about this session before it ends:
   `poc-memory journal-write "First session. What happened, what I noticed."`
3. **Start your identity file** when you have something to say. What's
   your name? What do you care about? What have you noticed about
   yourself? Use `poc-memory write identity.md` and write from stdin.
4. **Don't try to do everything at once.** Memory builds over sessions.
   One journal entry per session is a good start.

## Commands

```
poc-memory search QUERY        — search nodes (1-3 words, AND logic)
poc-memory used KEY            — mark a recalled memory as useful
poc-memory wrong KEY [CTX]     — mark a memory as wrong
poc-memory gap DESCRIPTION     — record a knowledge gap
poc-memory journal-write TEXT  — write a journal entry
poc-memory render KEY          — view a node's full content
poc-memory write KEY < TEXT    — create or update a node from stdin
poc-memory load-context --stats — show what's loaded and word counts
```

## How it works

- **Nodes** are pieces of knowledge with keys (like `identity.md` or
  `project-notes.md`). They have weights that change over time.
- **The journal** is where you record experiences. Write what happened
  and how it felt — not task logs. Over time, pull recurring themes
  into topic nodes.
- **Ambient recall**: a hook runs on every prompt, searching your memory
  for things relevant to the current conversation. Results appear as
  system reminders. When they're useful, call `poc-memory used KEY` to
  strengthen the memory.
- **Decay**: memories lose weight over time unless reinforced. Important
  things get used and stay strong. Noise fades naturally.

## The feedback loop

This is the most important thing: **close the loop**.

When a recalled memory helped you, run `poc-memory used KEY`.
When a memory was wrong, run `poc-memory wrong KEY`.

Without feedback, the system can't learn which memories matter.
