One install. The full team — 14 specialists, 9 always-on protocols, 6 vertical architects, 13 vendor Stacks. v4 ships as a single coordinated skill; per-tier installs are gone.

Software is a team sport.
So is your AI.

Most AI tools give you an assistant. etyb.ai gives you a company — one orchestrator, 20 senior specialists, and 9 always-on protocols enforcing real engineering culture on every request. The team stays assigned through the plan, updates its own deliverables, and verifies its work before claiming done.

Typical AI assistant
  • One general assistant for every role
  • Context resets every conversation
  • No process, protocols, or accountability
  • Answers provided, delivery not included
etyb.ai
  • Full team activated on demand
  • Living plans, persistent context
  • TDD, review, and verification built-in
  • Full delivery. Verified output.

One request.
The whole team activates.

01

You describe the work

A feature, a system, a bug, a refactor. Natural language or technical spec. The orchestrator handles both.

build a fintech payment API with auth, idempotency, and webhooks
02

etyb routes

The CTO skill. Determines which experts are needed, what protocols apply, and creates a living execution plan.

Experts execute

Domain experts take ownership of their areas. TDD first, verification before claims, review before merge.

Verified delivery

Nothing ships without evidence. Tests pass. Code reviewed. Plan updated. You get working software.

42 / 42 tests green

Always-on engineering culture
TDD: no code without a failing test
Verification: five questions before done
Debugging: root cause first, no blind retries
Review: push back with evidence
Plan execution: one task at a time

The engine
under the hood.

etyb-skills · v4 · MIT

etyb-skills is the open-source foundation we use internally. v4 collapsed the architecture into one coordinated skill (/etyb) backed by 20 specialists, 9 always-on protocols, 6 vertical architects, and 13 vendor Stacks — all shipping in one repo, read from disk at runtime.

Portable by design. Runs on Claude Code (flagship, hook-enforced gates), OpenAI Codex, and Google Antigravity. Any agentskills.io-compliant platform, one install script. Inspect etyb. Read the protocols. Fork the references.

13 vendor Stacks.
Shipped with the install.

Stack Packs are knowledge overlays that load across your existing etyb team when work involves a specific platform. The team doesn't grow — it learns the platform. Same backend-architect writes the Lambda handler; same security-engineer enforces the IAM boundary. The overlay teaches them how to do it the way the platform expects, currency-stamped to a known date.

Three orthogonal axes: specialists + protocols + Stack Packs. v4 ships 13 vendor Stacks in-repo — no separate fetch, no docs site, no per-stack license.

20 specialists. 9 protocols.
One coordinated skill.

Every role has defined expertise and process obligations. v4 collapsed the team into a single skill (/etyb) with the references inside — no peer skills competing at trigger time, no per-tier installs. Click any node to inspect it. They stay assigned. They don't give up.
