Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02370 | $0.02370 |
| Opus 5.5 | $0.00948 | $0.00948 |
| Sonnet 5.5 | $0.00474 | $0.00474 |
| Haiku 4.5 | $0.00237 | $0.00237 |
Grade A, and why
living-memory-engine AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts
The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This file provides guidance to Codex (Codex.ai/code) when working with code in this repository.
What this is
A personal living-memory chat: talk forever to an entity (the star persona is เชียงใหม่, a province that senses the real world and greets you first). Instead of stuffing the context window, a TypeScript memory engine decays / consolidates / crystallizes memories so a single thread never overflows — each turn the LLM sees only a small retrieved working set. The thesis driving current work: for a local-first entity, self-awareness (knowing its own state) > raw model intelligence.
Side project of the Viibe World OS workspace (not the HomeLog sprint). Resume context lives in NEXT-SESSION.md; design specs and TDD plans live under docs/superpowers/{specs,plans}/.
Three parts (one git repo)
| Dir | Status | What |
|---|---|---|
web/ |
ACTIVE — all current work | Plain Vite + vanilla TypeScript app (no React/framework) + uicp drawer. The product. |
engine/ |
Stable substrate | @nature-labs/living-memory-engine — framework-agnostic TS memory engine. Consumed by web/ via file:../engine (its prebuilt dist/). |
mobile/ |
FROZEN — do not touch | Old Expo/React Native app. Superseded by web/. Not deleted; not maintained. |
Commands
First-time setup — the engine must be built before the web app can import it (web/ links the engine's prebuilt dist/ via file:../engine, and dist/ is gitignored):
cd engine && npm install # the `prepare` hook builds dist/ automatically on install
cd ../web && npm install && npm run dev # → http://localhost:5173 (Vite)
Then, working in web/ (the app):
cd web && npm test # vitest (run once)
cd web && npx vitest run test/selfstate.test.ts # a single test file
cd web && npx tsc --noEmit # typecheck (expect 0 errors)
The engine has its own suite:
cd engine && npm test # vitest
cd engine && npm run build # tsc -p tsconfig.build.json → dist/ (REQUIRED after editing engine/src — see below)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
