In this new era, the work that really needs our attention is no longer repetitive coding, but higher-level business understanding and architecture design. The future workflow I have in mind is: understand the business → think through the architecture → write a Proposal → review the Proposal → let the Agent implement it automatically, then move on to the next Proposal.
That thinking led me to build FylloCode — a step from Vibe Coding toward Agentic Coding.
How FylloCode Solves It
FylloCode enforces a structured workflow that separates thinking from doing:
┌──────────┐ ┌────────────────┐ ┌───────────┐ ┌───────────┐
│ Task │ ──→ │ Chat/Proposal │ ──→ │ Apply │ ──→ │ Archive │
│ │ │ │ │ │ │ │
│ What to │ │ Agent explores │ │ Agent │ │ Specs │
│ work on │ │ codebase and │ │ implements│ │ updated, │
│ │ │ writes a plan │ │ the plan │ │ change │
│ │ │ │ │ │ │ recorded │
│ │ │ ➜ YOU REVIEW │ │ │ │ │
└──────────┘ └────────────────┘ └───────────┘ └───────────┘
Task — Pick a task from your local list or synced from platforms like Yunxiao. One click sends it to Chat.
Chat / Proposal — The Agent explores your codebase, asks clarifying questions, and produces a structured proposal (what to change, which files, acceptance criteria). The Agent is prohibited from writing code in this stage. You review, edit, and approve the proposal before anything else happens.
Apply — A fresh Agent session implements the approved proposal task-by-task. It reads only the proposal artifacts — not the Chat history — so every decision must be captured in writing, not left in context-window memory.
Archive — Specs are updated, the change is recorded with full traceability. Your project's knowledge base grows with every shipped change.
Why Separating Thinking from Execution Matters
Most Coding Agents understand a task and write code in the same session. Any misunderstanding becomes code directly, and code is expensive to review. FylloCode physically separates understanding from execution. Misunderstandings can only become proposal text — and text is cheap to review. A 2-minute proposal review catches problems that would take 20 minutes to find in a diff.
Features
Agent Protocol (ACP)
FylloCode connects to any Coding Agent through ACP (Agent Client Protocol). Claude Code, Codex, or any ACP-compatible agent — one protocol, one interface, without juggling a pile of terminal windows.
There are currently 35 agents available in the ACP Registry, with support for parallel chats and parallel Proposal Apply runs.
