Specification-first Agent OS

Stop prompting.
Start specifying.

Ouroboros turns ambiguous ideas into executable specifications, replayable agent work, verified outcomes, and a learning loop that improves the next run.

A workflow that earns the right to execute.

Most agent failures begin before code is written: assumptions stay hidden, intent drifts, and “done” is accepted without proof. Ouroboros makes the reasoning lifecycle explicit.

01

Interview

Socratic questions expose hidden assumptions and reduce ambiguity before implementation.

02

Seed

Intent becomes an immutable specification with constraints and acceptance criteria.

03

Execute

Agent work runs against the Seed through a replayable, observable execution contract.

04

Evaluate

Mechanical, semantic, and consensus gates test the result instead of trusting a completion claim.

Clarity before velocity.

SOCRATIC CLARITY

Question the request

Surface what the human and the agent do not yet know before those gaps harden into architecture.

ONTOLOGICAL PRECISION

Solve the root problem

Separate symptoms, entities, constraints, and desired outcomes so the system builds the right thing.

EVOLUTIONARY LOOPS

Learn across runs

Feed evaluation evidence back into the next generation rather than repeating the same prompt with more force.

One OS. Multiple agent runtimes.

Ouroboros is local-first and runtime-aware. Use the same specification and verification discipline across Codex, Claude Code, OpenCode, Hermes, Gemini, Kiro, Copilot, and Pi.
