Chapter 02 — Open engineering architecture

Your engineering stack.
In one ecosystem.

10 open-source modules across 8 engineering domains, orbiting one engineering core. Shared direction, independent utility, no fake integration story — hover a node to trace what it connects to.

Suiflex Open engineering

Choose an outcome. The stack reorganises around the tools that can help — without pretending they are tightly coupled.

Engineering modules,
not isolated products.

Each tool solves a focused problem. The flow context shows where it can sit before or after other Suiflex work — and the camera moves to its module in the core as you arrive.

01 / Development usable

Terminal coding harness

Arsy Code

An open-source terminal-first coding-agent harness for context, permissions, parallel work, and durable engineering evidence.

CLIEvent logPolicy engine

ProblemHow should a coding agent understand repository rules, choose tools, ask for approval, and keep a trustworthy event trail?

ApproachAn event-log core lets policy decide whether proposed actions run directly, in a sandbox, after approval, or not at all.

Repository ↗ v0.10.0

arsy — event log

$ arsy "add retry to the upload client"

02 / AI agents in development

General-purpose agent harness

Arsy

An open-source runtime for agents that plan, use tools, remember context, and act under auditable policies.

Agent runtimePolicy-aware

ProblemHow can one agent foundation support research, automation, operations, and long-running work without becoming a coding-only tool?

ApproachA policy-aware runtime separates the hot-path kernel from ecosystem workers, turning goals, tools, and context into auditable action.

Repository opens with the first public release coming soon

Meeting capture and recall

Companion

Turn Google Meet and Microsoft Teams calls into structured Markdown notes you keep.

Browser extensionDesktop appMarkdown

ProblemDecisions and action items from a call are gone the moment the meeting ends.

ApproachA browser extension reads Meet and Teams captions live; a desktop app files each call as a local Markdown note — summary, timeline, decisions, action items, risks, open questions.

suitest

A self-hostable, MCP-native QA platform for deterministic and agent-driven testing.

PythonTypeScriptMCP

06 / AI agents experimental

Resource-aware agent tooling

FluxGuard

Resource awareness for coding agents before every major operation.

RustMCPCLI

ProblemCoding agents need to know when quota, context, request limits, or budget flow is close to exhaustion.

ApproachA Rust MCP layer normalizes resource signals into concise execution advice so agents can adapt before expensive work.

Repository ↗ v0.2.2
