Codex-build

TUEO's coding engine: it makes AI employees truly do the work and truly produce — no more self-reported agents, but a real coding execution engine with enterprise identity boundaries and auditable trails.

Core capabilities

From "I claim it is done" to "it is done"

The engine handles "how", and the server decides "what is allowed and what is recorded" — AI coding delivery becomes trustworthy.

Capability · 01

Real coding execution

Reads code, edits files, runs tests, commits and opens MRs in a real repository workspace — producing real files, real diffs and real branches, not an AI narrating "I did it".

Capability · 02

Codebase understanding

Code indexing, a scope graph and workspace discovery support cross-file tasks; a context bundle (role constraints + work-order spec/plan/AC + model routing) is materialized and injected per task.

Capability · 03

Managed runtime

Driven by the desktop and sandbox through a managed protocol: long-lived sessions, real-time event streaming, and permission and approval cards. Native built-in login is fully locked down, and the managed entry point binds to enterprise identity.

Capability · 04

Sub-agent collaboration · hard gate

Sub-agents start in parallel or nested by task complexity, but every sub-agent must pass engine-level consent confirmation before its initial spawn — "whether to use sub-agent collaboration" becomes a decision the enterprise can confirm.

Capability · 05

Enterprise identity boundary

Every session is pinned to an identity subject (issuer / tenant / user) with cross-tenant access failing closed; engine actions run in a restricted sandbox, and tenants sharing an installation are invisible to each other.

Capability · 06

Credentials never leave the server

The engine holds no model-provider keys — it receives short-lived session tickets issued by the server, forwarded to the real model through an engine gateway. The real key never leaves server-process memory.

Capability · 07

Multimodal: vision and voice

A text-based primary model can still see and hear: images are turned into descriptions by an auxiliary vision model, and voice runs through the engine's built-in voice runtime. Model routing is always decided server-side.

Capability · 08

MCP business-capability integration

Work orders, knowledge, attachments and messages enter the engine through a single standard MCP exit — business capabilities are not scattered across the engine side, and credentials are never passed down to clients.

Capability · 09

Trust and traceability governance

Repositories with hooks or configuration are not loaded for execution by default (the Folder Trust gate). A patch ledger plus source-equivalence checks can answer at any time: where did this code come from, what changed, and can it be rolled back.

The work order coding loop

From "please fix this bug" to a mergeable MR

The AI dev team completes work orders in real repositories — no simulated progress, but real edits, real tests, and real commits.

01

Work order intake

Triage → spec → plan → AC; the context package is materialized and injected into the engine with each task.

02

Sandboxed execution

Inside the Executor sandbox: clone → read code → edit files → run tests.

03

Self-verification

Real browser screenshots + a vision model judging the render — not jsdom guesswork.

04

MR and backfill

Push branch → open MR → code review → merge gate → backfill the work order.
