Open Source

Open, vendor-neutral infrastructure from Cognous.

Cognous publishes reference infrastructure in public. Adopting it requires no vendor agreement.

Who Open Control Stack is for

Built for teams moving agents into production.

The same artifacts serve engineering and governance — one record, read four different ways.

Enterprise AI teams

Move agents into production with governance built in, not bolted on.

Platform engineers

Add a runtime control layer without adopting a whole framework.

Security & governance

Review what an agent did — and prove it — in business-readable form.

Application developers

Declare an agent's actions once; get authorization, records, and replay.

Skills

Open reasoning protocols for general-purpose AI.

Instruction-layer protocols that can be inspected, versioned, forked, tested, and reused across AI assistants. The Portable Reasoning and Research Intelligence protocols ship as SKILL.md-based Skills, with installation guides for ChatGPT, Claude, Gemini, and GitHub Copilot.

Portable Reasoning Protocol

A portable reasoning layer for more rigorous, evidence-bounded AI work.

Adapts its rigor to the task: simple work stays simple; consequential, ambiguous, or difficult-to-reverse work receives deeper scrutiny. It eliminates invalid transitions between ideas, evidence, claims, and actions.

Adaptive rigorFour invariantsHallucination control
Who it is for

Founders, executives, analysts, researchers, product and engineering teams, legal, risk, and governance professionals — anyone using AI for consequential decisions.

Skill · v1.0

Research Intelligence Protocol

Disciplined discovery and cross-domain structural abstraction.

Two components kept deliberately distinct: the Discovery Protocol turns reality into structured evidence; the Abstractor of Abstractors turns evidence into tested, transferable invariants.

Who it is for

Researchers, R&D and engineering teams, architects, consultants, due-diligence, technology-transfer, patent, and root-cause analysis teams.

TFA Protocol

Say what is true. Ask for nothing. Protect their next move.

A lightweight, optional behavioral protocol for AI interaction, built on three rules — Truth, Freedom and Agency — with implementation and evaluation guidance that explains the rules without turning them into an authority system.

TruthFreedomAgency
Who it is for

Teams building or reviewing AI assistants who want a small, shared vocabulary for judging interaction quality — calibrated claims, no unnecessary extraction, and user choice kept open.

Start with the open-source stack.

Thirteen open components for governed agent action. Adopt one, or run the bounded reference end to end.
