HARNESS 01
The TDD Orchestrator
Delegates work to isolated red, green, and refactor subagents, test-first by design.
Platform Architecture · The Engineering Harness · Deterministic Execution
Stop guessing what your AI is building.
Specify the architecture.
Standard AI coding assistants operate as black boxes, injecting unverified code and generating massive context debt. The Realized.Dev platform replaces this chaos with a deterministic, multi-agent engineering harness.
v1.0 — The Deterministic Engine
- Specification
- Spec is Law
- TDD
- Red → Green
Recorded in Git and pull-request history
Failing test before code
How It Works
The Three Layers of Autonomous Engineering
We strip autonomy away from the execution layer and give it to the specification. The harness's rules require an accepted specification and a failing test before any implementation. The harness includes hooks that check agent actions, and we're hardening them for cloud runs.
- L1
The Harness
Read-only constraints
- Read-Only Plan Modes
- Explicit execution plans
- No repository mutation
- L2
The Manager
Backlog steward
- Local work-item queue
- Read-only spec audits on demand
- Ready-to-execute plans
- L3
The Workforce
Parallel execution
- Parallel subagent waves
- One feature branch per item
- Cloud PR intake checks. A person approves every merge.

HARNESS 02
Automated Gatekeeping
Automated QA gates verify that shipped code passes tests before version control operations occur.
HARNESS 03
Merge firewall
The harness includes hooks that check agent actions, and we're hardening them for cloud runs. /intake checks cloud pull requests in an isolated worktree. Agents open draft pull requests. A person approves every merge.
Core Philosophy · Spec is Law
The specification is your single source of truth, recorded in Git and pull-request history.
The specification directory, not the chat history, decides what counts as done. Changes are reviewed against it before they reach your main branch.
