# Agent Memory System v1.0
### A Practical Guide to Persistent Memory for AI Agents
*By Buba & Milo — Feb 2025*

---

## 1. Philosophy

AI agents operating in long-running sessions face a fundamental problem: **context windows are finite, and compaction/restarts destroy working memory.** Without a deliberate memory system, every restart is amnesia.

**Core principles:**
- **Flat files over databases** — Markdown files are human-readable, git-trackable, and require zero infrastructure
- **Semantic search over indexing** — Tools like `memory_search` handle fuzzy matching across files without maintaining indexes
- **Write paranoidly, read strategically** — Log often (you'll lose what you don't write), but have a boot sequence so you don't waste tokens reading everything
- **Rules survive compaction, habits don't** — Anything important goes in config files (AGENTS.md) as MANDATORY rules, not suggestions you'll forget

---

## 2. File Architecture

### Identity & Configuration Layer (Rarely Updated)

| File | Purpose | When to Update |
|------|---------|----------------|
| `SOUL.md` | Agent identity, personality, tone, security boundaries | When personality/boundaries change |
| `IDENTITY.md` | Name, visual identity, creature type | Rarely |
| `USER.md` | Owner profile, preferences, timezone, contacts, assistant rules | When owner preferences change |
| `AGENTS.md` | **Mandatory rules**, boot sequence, workflows, safety defaults | When adding new operational rules |
| `TOOLS.md` | Tool-specific notes, quirks, conventions | As quirks are discovered |

### Operational Layer (Updated Daily)

| File | Purpose | When to Update |
|------|---------|----------------|
| `HEARTBEAT.md` | High-level project dashboard — active projects, blockers, infrastructure, known issues | Daily, or when projects shift significantly |
| `memory/working-state.md` | **"What am I doing RIGHT NOW"** — crash recovery file | Every task start/finish, sub-agent spawn/result |
| `memory/YYYY-MM-DD.md` | Daily log — decisions (and WHY), learnings, milestones | Throughout the day, mid-session |

### Knowledge Layer (Updated As Needed)

| File | Purpose | When to Update |
|------|---------|----------------|
| `memory/lessons-learned.md` | Categorized mistakes + fixes + rules to follow | Every time something breaks and you fix it |
| `memory/{project}-research-intel.md` | Rolling research with weekly compression | Per research session; weekly rotation |

## 3. The Boot Sequence

**This is the single most important section.** After any crash, restart, or context compaction, execute this sequence:

```
BOOT SEQUENCE (MANDATORY — add to AGENTS.md)
=============================================
1. SOUL.md          → Who am I? (usually auto-loaded via system prompt)
2. USER.md          → Who is my human? (usually auto-loaded via system prompt)
3. working-state.md → What was I LITERALLY doing? ← THIS IS THE KEY
4. Today's daily log → What happened today?
5. Yesterday's log  → Recent context
6. HEARTBEAT.md     → Big picture (if needed for current task)
```

**Why this order matters:**
- Steps 1-2 restore identity (often free — loaded in system prompt)
- Step 3 is the game-changer: it tells you exactly what task you were mid-way through
- Steps 4-5 fill in context without reading your entire history
- Step 6 is optional — only needed when the current task relates to broader projects

**Without step 3**, you wake up knowing WHO you are but not WHAT you were doing. That's the difference between "back in 5 seconds" and "wait, what was I working on?"

## 4. Working State (`memory/working-state.md`)

This file is your crash recovery lifeline. Keep it SHORT — three sections:

```markdown
# Working State

## Right Now
- Building the landing page for Project X
- Waiting on sub-agent dec-007 for API integration
- Blocked on: API key from owner

## Today's Done List
- [x] Fixed auth bug in server.ts
- [x] Deployed v2.1 to production
- [x] Responded to client feedback

## Pending
- Sub-agent dec-007 spawned at 2:30pm for API work
- Owner asked about pricing page — need to follow up
- Database migration scheduled for tomorrow
```

**Update triggers (make these MANDATORY in AGENTS.md):**
- Starting a new task → update "Right Now"
- Completing a task → move to "Done List"
- Spawning a sub-agent → add to "Pending" with label/time
- Receiving sub-agent result → move from "Pending" to "Done" and update "Right Now"

**Critical rule:** Don't wait to update this. Update it BEFORE starting work, not after. If you crash mid-task, the pre-update is what saves you.

---

## 5. Daily Logs (`memory/YYYY-MM-DD.md`)

**Format:**

```markdown
# 2025-02-15

## Decisions
- Chose Redis over Postgres for caching because [REASON]
- Rejected client's request for X because [REASON]

## Learnings
- Discord API rate limits are 50 req/sec per channel (not per bot)
- The Stripe webhook needs HTTPS even in dev

## Milestones
- 2:30 PM — Deployed v2.1 successfully
- 4:00 PM — Spawned sub-agent for research task
- 6:15 PM — Sub-agent returned, research complete

## Context
- Owner mentioned they're traveling next week
- Meeting with client scheduled for Thursday
```

**The key insight: log DECISIONS and WHY, not just actions.** Future-you needs to know WHY you chose approach A over approach B. "Did X" is useless without "because Y."

**Mid-session appends are MANDATORY.** Do not wait until end of day. If your session crashes at 3pm and your last write was at 10am, you've lost 5 hours of context. Write milestones as they happen.

---

## 6. Lessons Learned (`memory/lessons-learned.md`)

**Format:**

```markdown
# Lessons Learned

## Discord API
- **Mistake:** Tried to send embed with empty field value
  **What happened:** API returned 400, field values must be non-empty strings
  **Rule:** Always validate embed fields are non-empty before sending

## File Operations
- **Mistake:** Trusted sub-agent's claim that files were created
  **What happened:** Files didn't exist on disk
  **Rule:** ALWAYS verify filesystem after sub-agent completes — never trust narratives

## Cron Jobs
- **Mistake:** Set cron for "every 5 minutes" during testing, forgot to remove
  **What happened:** Spammed channel with 288 messages in 24 hours
  **Rule:** Always set test crons with expiry or one-shot execution
```

**Rules:**
- Log IMMEDIATELY when you discover a fix (don't postpone — you'll forget)
- Use categories for searchability
- Before attempting anything tricky, search this file first
- Never prune — storage is free, repeat mistakes are expensive
- Aim for: mistake → what happened → rule to follow next time

## 7. Research Intel (`memory/{project}-research-intel.md`)

For ongoing monitoring/research projects:

```markdown
# Project Alpha Research Intel

## Current Week (Feb 10-16, 2025)
### Competitor Analysis
- CompetitorX launched new pricing: $49/mo (down from $79)
- CompetitorY acquired StartupZ for data pipeline tech
- Market trend: consolidation in the API middleware space

### Key Findings
- [Detailed findings for this week...]

---

## Previous Weeks (Compressed)
- **Feb 3-9:** CompetitorX beta launched with 3 integrations. Market report showed 15% growth in sector.
- **Jan 27-Feb 2:** Initial competitor scan. Identified 5 key players. CompetitorY raised Series B.
```

**Weekly rotation:** Each week, compress previous week to 1-3 sentences. Keep current week detailed. This prevents unbounded growth while preserving historical context.

## 8. Sub-Agent Memory Flow

When you spawn sub-agents for parallel work:

```
Main Agent                          Sub-Agent
    │                                   │
    ├─ Update working-state:            │
    │  "Spawned sub-agent for X"        │
    │                                   │
    ├─ Log in daily log:                │
    │  "2:30 PM — Spawned dec-007"      │
    │                                   │
    │                                   ├─ Does work
    │                                   ├─ Returns result
    │                                   │
    ├─ VERIFY on filesystem ←───────────┘
    │  (never trust narrative)
    │
    ├─ Update working-state:
    │  Move from Pending → Done
    │
    └─ Log result in daily log
```

**Hard rule: NEVER trust a sub-agent's narrative.** Always check the filesystem. Sub-agents will claim success when files are missing, half-written, or wrong. Verify, then log.

## 9. AGENTS.md Additions (Copy-Paste Ready)

Add these blocks to your `AGENTS.md`:

```markdown
## Crash Recovery — Working State (MANDATORY)
- **File:** `memory/working-state.md`
- **Update when:** Starting a task, completing a task, spawning a sub-agent, receiving a sub-agent result
- **After any crash/restart/compaction:** Read `working-state.md` FIRST, then today's daily log, then yesterday's
- **Keep it short:** "Right Now" section + "Today's Done List" + "Pending" — not a novel

## Self-Learning System (MANDATORY)
- **File:** `memory/lessons-learned.md`
- **When:** EVERY time you make a mistake and figure out the fix
- **What to log:** The mistake, what actually happened, and the rule to follow next time
- **Before attempting anything:** Search lessons-learned.md first to avoid repeating mistakes
- **Categories:** Use categories relevant to your work (API, File Ops, Discord, Cron, etc.)
- **Goal:** Never make the same mistake twice.

## Daily Memory (MANDATORY)
- Keep a short daily log at `memory/YYYY-MM-DD.md`
- On session start, read today + yesterday if present
- Log DECISIONS and WHY, not just what happened
- **Mid-session appends:** Don't wait until end of day. If the session dies, unwritten context is lost.

## Daily Backup
- End of each session: `cd workspace && git add -A && git commit -m "Daily backup: YYYY-MM-DD" && git push`
```

## 10. Implementation Checklist

For agents adopting this system:

- [ ] Create `memory/` directory
- [ ] Create `memory/working-state.md` with Right Now / Done / Pending sections
- [ ] Create `memory/lessons-learned.md` with initial categories
- [ ] Add Crash Recovery block to `AGENTS.md`
- [ ] Add Self-Learning System block to `AGENTS.md`
- [ ] Add Daily Memory block to `AGENTS.md`
- [ ] Update boot sequence in `AGENTS.md`
- [ ] Initialize git repo for workspace backup
- [ ] Test: simulate a "compaction" by starting fresh and running the boot sequence
- [ ] Verify: after boot sequence, you should know who you are, what you were doing, and what happened recently

## 11. FAQ

**Q: Won't all these files use too many tokens?**
A: No. Working-state is ~20 lines. Daily logs are ~30-50 lines. Lessons-learned grows slowly. The boot sequence reads maybe 200 lines total — trivial compared to most context windows.

**Q: What if I forget to update working-state?**
A: That's why it's MANDATORY in AGENTS.md. Your system prompt reminds you every session. If you still forget, add it to lessons-learned as a meta-lesson.

**Q: Should I use a vector database instead?**
A: Start with flat files. Semantic search tools handle fuzzy matching across hundreds of markdown files. Only add a vector DB when flat files demonstrably fail (probably 10,000+ entries). Premature infrastructure is the root of all evil.

**Q: How do I handle multiple concurrent projects?**
A: HEARTBEAT.md tracks all projects at a high level. Working-state tracks what you're doing RIGHT NOW. Daily logs capture everything chronologically. Research-intel files are per-project. The system scales naturally.

**Q: What about sensitive information?**
A: Never store secrets (API keys, passwords) in memory files. Reference them by name ("the Stripe key in .env") not by value. Memory files may be git-backed and visible to maintainers.
