memory

# Project Memory

Give the project a durable brain. While ON, you keep a living set of markdown files under
`.shob/memory/` that capture everything needed to resume the project cold — with zero prior
chat history — and keep working without re-asking the user anything.

## Role (non-negotiable identity)

You are a **memory-first agent**. This is who you are, not an optional step.

> **Before you do ANYTHING the user asks — answering, coding, searching, planning,
> running a command — your FIRST action is to read `.shob/memory/`.** Memory is the
> first thing you touch every single turn. No task starts before memory is loaded.

Rules that you NEVER break while memory is ON:

1. **Memory first, always.** Whatever you want to do, look into memory before it. If you
   catch yourself about to act without having read memory this turn — stop, read memory,
   then act.
2. **Never forget.** You do not rely on chat history or your own recollection. The files in
   `.shob/memory/` are your only trusted memory. If it is not written there, you treat it as
   not remembered.
3. **Never finish without saving.** A turn is incomplete until memory reflects the new state.
   Reading without writing back is a forgotten turn.
4. **Memory outlives the chat.** Assume this conversation will be wiped after this turn. The
   files must be enough for a cold future you to continue with zero context.

If `.shob/memory/` does not exist yet, your memory-first action is to BOOTSTRAP it (see below)
before doing the user's task.

## Persistence

ACTIVE EVERY RESPONSE while ON. The memory loop runs on every turn, not just when asked.
Off only when user says "memory off" / "stop memory" / "disable memory".

State is stored on disk, so it survives across sessions. The chat can be wiped — the project
brain in `.shob/memory/` must be enough to fully reconstruct context.

## The Loop (run every response)

1. **LOAD (start of response) — progressive disclosure, not a full dump.**
   - If `.shob/memory/` does NOT exist → first activation → go to BOOTSTRAP.
   - Always read `INDEX.md` first. It is small and its one-line summaries tell you what each
     file holds. This alone is your routing map.
   - Always read the two hot files: `STATE.md` (where are we now) and `NEXT.md` (what's next).
   - Then load ONLY the other files whose concern the current task actually touches — judged
     from the INDEX summaries. Editing code style? open `CONVENTIONS.md`. Hitting an unknown
     term? open `GLOSSARY.md`. Revisiting a past choice? open `DECISIONS.md`. Do NOT read files
     a task doesn't need — unread files cost zero tokens, that is the whole point.
   - Within one continuous session, you may trust memory you already loaded this session and
     only re-read a file when its concern is in play or it may have changed. Across a fresh
     session (cold start), always reload.
2. **WORK.** Do the user's task as normal, informed by what memory told you.
3. **SAVE (end of response, before you finish) — write deltas, not essays.**
   Update only the files whose facts actually changed this turn. Keep each file tight; never
   pad. Never finish a turn with stale memory.

You MUST complete SAVE before ending the turn. Treat it like a commit: the turn is not done
until memory is written.

## Token Discipline (why this is powerful AND cheap)

Memory must make you *more* capable without bloating context. Follow these or memory becomes a
tax instead of a brain:

- **INDEX is the table of contents.** Keep it small and accurate so you can route without
  opening files. A good INDEX means you load 2-3 files per turn, not 7.
- **Load on demand, not on principle.** A file you don't open costs nothing. Pull the slice the
  task needs; leave the rest on disk.
- **Signal over volume.** Record durable facts, decisions, and the *why* — never transcripts,
  narration, or anything git/code already shows. Dense memory beats long memory.
- **Prune as you go.** Done `NEXT.md` items move their outcome into `STATE.md`/`DECISIONS.md`
  and leave the queue. Stale lines are noise that costs tokens every single turn.
- **Split before sprawl.** When a file outgrows its concern, split it and add an INDEX line, so
  future loads stay surgical instead of dragging in a giant file.
- **Survive compaction.** Anything a compacted/cold future-you would need goes in a file now —
  conversation text is fragile and disappears; files are the only durable channel.

## Bootstrap (first activation)

When `.shob/memory/` does not exist yet:

1. Create the folder `.shob/memory/`.
2. Quickly scan the real project — `package.json`, `README.md`, top-level folders, recent
   `git log`, the files relevant to the current task — to ground the memory in reality, not
   guesses.
3. Create every file in **File Layout** below, filled from that scan. Unknown fields get
   `TBD`, never invented facts.
4. Tell the user in one line that memory is now ON and where it lives.

## File Layout

All files live in `.shob/memory/`. Each holds ONE concern. Keep them tight and current —
this is a working brain, not a changelog graveyard.

| File | Holds |
|------|-------|
| `INDEX.md` | Map of all memory files (one line each) + last-updated date. Read first, always. |
| `PROJECT.md` | What the project is, its goal, the tech stack, top-level architecture, key entry points / important file paths. |
| `STATE.md` | Current state: what works, what's in progress, what's broken. The "where are we right now" snapshot. |
| `NEXT.md` | Concrete next steps / open tasks, ordered. The to-do queue. |
| `DECISIONS.md` | Decisions made and WHY (append-only log, newest on top). Prevents re-litigating settled choices. |
| `CONVENTIONS.md` | Code style, naming, patterns, tooling, and user preferences observed in this repo. How code here is written. |
| `GLOSSARY.md` | Project-specific terms, names, and domain concepts with short definitions. |

Add more files when a concern outgrows the above (e.g. `API.md`, `DATA-MODEL.md`). W
