Welcome to Thoth-ATO

Thoth-ATO is the governed AI engineering co-pilot. Signed verdicts. In a local cycle, your source code and secrets stay on your machine — the governed cycle commits an Ed25519-signed verdict to your git for immutable audit logging.

Generic AI coding assistants suggest text into a chat box. Thoth-ATO runs a governed cycle — in your editor or any terminal, on any model — and emits a cryptographically signed verdict you can verify, audit, and ship.

  • Signed verdicts — Every cycle is signed with Ed25519 keys stored in Google Cloud KMS. Anyone can verify a verdict independently against the public key endpoint (GET /api/v1/judge/public-keys/{kmsKeyVersion}) — no account, no trust required.
  • Local execution — The Claude Code plugin uses Claude Code’s Write, Edit, and Bash tools to produce real files, real tests, and real git commits in your editor. In a local cycle, your source code and secrets stay on your machine — the governed cycle commits an Ed25519-signed verdict to your git for immutable audit logging.
  • Any model, from any terminal — Dispatch a remote cycle to run the full cycle on Anthropic, OpenAI, Gemini, Vertex, Ollama, or any OpenAI-compatible endpoint via the hosted control plane (no Claude Code required) — from any terminal, including the integrated terminal of your IDE. A standalone thoth CLI for any terminal and CI is in pre-launch beta — installable from source today, published to npm at the v7.2 launch gate. Native IDE extensions are on the roadmap.
  • Compliance-ready — Signed verdicts plus the KMS audit trail satisfy evidence requirements for the EU AI Act high-risk obligations (August 2026), the Colorado AI Act (June 2026), SOC2 Type II Trust Services Criteria, and ISO 27001:2022 Annex A.

Thoth-ATO is built for engineering teams that have to prove the AI didn’t ship something they would not have shipped themselves. Three canonical use cases:

A neobank ships a credit-risk feature touched by an AI assistant. The auditor asks: “Show me the change record. Show me the security and bias review. Show me who approved this.” Thoth-ATO’s signed verdict is the change record, principle scores are the review, and the approval-gate log is the sign-off.

A digital therapeutics vendor under HIPAA + FDA SaMD oversight uses AI to refactor a clinical decision module. The verdict captures the constitution-enforced Security and Anti-fragility thresholds, ties the deliverable hash to the KMS audit log, and produces a verifiable record the QA team archives in the design history file.

A B2B SaaS vendor ships an AI-assisted feature into the EU and Colorado markets and must produce per-change risk evidence. Thoth-ATO’s signed verdict is the change record, the principle scores are the risk review, and the KMS audit trail maps to EU AI Act Article 12 record-keeping and Colorado AI Act SB 24-205 obligations.

Thoth generates code where you work — in your editor in a local cycle, or on the provider you choose via a remote cycle — never in our cloud against your repo. In a local cycle, your source code and secrets stay on your machine; the governed cycle commits an Ed25519-signed verdict to your git. A remote cycle — when you opt in to /thoth --remote — runs on the provider you choose and returns a signed verdict and a JSON spec. Never your source. Never your secrets. Never your data.

Your source code stays in your editor. Your cloud stays yours. Your audit trail is cryptographically yours.
