otto AGENTS.md

otto AGENTS.md is an instructions file for Codex, OpenCode from otto-haus/otto. It costs 2,449 tokens per session, scanned A, original, MIT.

Repository instructions for otto, a project moving toward becoming a Paperclip extension that uses Letta for agent memory and runtime. They describe the product direction, architecture, and development boundaries.

In plain words
What is it for?
Guiding work on the local Letta adapter, Paperclip integration, provider configuration, agent memory continuity, and related repository decisions.
Why use it?
They give coding agents the current product context and highlight assumptions that must be resolved before implementing connected services.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

otto 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 3d 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.

Direction (read first): otto → Paperclip plugin

otto is pivoting from a standalone Electron shell into an extension of Paperclip (the open-source agent-orchestration app). Mental model: Paperclip is the office, otto is the culture layer, Letta is the memory/runtime.

  • v1 (in progress): "use Letta from Paperclip." Ship a letta_local external adapter at packages/paperclip-letta-adapter that drives an existing local Letta agent from a Paperclip issue (memory continuity via the Letta agentId). It targets Paperclip's external-adapter contract: a package exporting createServerAdapter(): ServerAdapterModule, installed via POST /api/adapters (isLocalPath: true). Provider keys live in Letta; the adapter only observes a providerConfigured boolean, never the keys.
    • Network boundary: the adapter runs where the Paperclip server runs. v1 proof target is a local Paperclip host + an existing local Letta runtime on the same Mac. Cloud Paperclip → remote Letta or an explicit tunnel is a later step. This is the assumption most likely to be wrong; resolve it first.
  • v2: culture loop ships as a Paperclip plugin (receipts to issues; correction → proposal → ratification → Standard). Adapters and Plugins are two different Paperclip surfaces — v1 is an adapter, not a plugin. v1 carries only a tiny receiptRef placeholder, no real culture.
  • Do NOT archive the Electron shell in v1. Keep apps/desktop/ as the internal lab / Letta console; build the adapter in its own package. Archive shell surfaces only after the Paperclip adapter completes one real issue round-trip. The governance layer (standards/, practices/, routines/, receipts/, skill/, autonomy/) is kept for v2.

The legacy product rules below still describe the active desktop shell (kept as the lab). They remain in force for apps/desktop/ (e.g. provider keys belong in Letta; do not show mock data; only Sebastian accepts done).

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.
