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 17d 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.

AGENTS.md

Product name: Otto (renamed 2026-07-08 from "Fincept Local Terminal"). The vision is an effortless, AI-operated local finance terminal — the user just gives commands. The "Fincept" references below are the clean-room heritage and boundary (the original product that was observed, never copied); they are intentionally kept, not the product name.

Purpose

This repository is a clean-room local rebuild of Fincept Terminal for local self-use. The governing product goal is functional and workflow parity with the observed Fincept Terminal experience while avoiding Fincept branding, assets, commercial copy, runtime binaries, and implementation-source copying. The source of truth is the research evidence under docs/reference/, direct observation of the installed app's behavior, and this file; it is not another project roadmap.

Non-Negotiable Boundary

  • Do not implement or reference D:\Crypto-Trading goals unless the user explicitly asks.
  • Do not treat FINCEPT_TO_CRYPTO_TRADING_HANDOFF.md as this repo's roadmap.
  • Do not copy Fincept branding, logo, trademarks, commercial copy, subscription mechanics, CR/credits, billing flows, or installer/runtime binaries.
  • Do not read, copy, port, or adapt implementation source from D:\FinceptTerminal\app\scripts or any installed Fincept package source into executable paths. Use observed UI behavior, screenshots, JSON logs, public documentation, and independent implementation.
  • Live trading parity is in scope only through independently implemented, explicitly planned local modules. No live order path, private API key flow, real balance read, margin, leverage, short exposure, or derivatives execution may be reachable until a dedicated safety contract exists with local secret storage, explicit live-mode opt-in, confirmation gates, audit logs, kill switch behavior, and tests proving paper/live isolation.
  • Keep all user data, layouts, logs, reports, backtests, screenshots, and settings local by default.

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.
