Vibe coding

Give your agents a real plan.

AI agents ship features faster than anyone can write the ticket. NexuSync is project management for vibe coding: it compiles your intent into specs, and your agents execute them over MCP.

The problem

Vibe coding outruns the backlog

Vibe coding won adoption because it collapsed the distance between an idea and working code. It also collapsed the habits that kept a team oriented: the ticket, the spec, the reason a change was made.

Code outruns the record

An agent ships a feature in less time than it takes to write the ticket for it. So the ticket never gets written, and the backlog stops describing what the product actually does.

> actually split the token cache first

> skip refresh tokens for now

Intent lives in scrollback

The why behind each change is a prompt in a chat session. Weeks later, nobody can say which requirement a module serves, or whether it was ever a requirement at all.

Agents rebuild and collide

Without a dependency-aware plan grounded in the codebase, every session starts from zero. Agents redo work that exists and step on work that is in flight.

Definition

What is vibe planning?

Vibe planning is the practice of giving AI coding agents a structured, machine-readable plan to work from. You describe intent in natural language; a planning layer compiles it into EARS-format specifications and dependency-ordered stories; your agents pull that work over MCP, execute it, and report progress back.

Vibe coding decides how the code gets written. Vibe planning decides what gets built, in which order, and why.

How it works

Describe, compile, execute.

Three steps from an idea to agent-executed work over MCP, with your review in the middle of every one.

01

Describe the intent

Tell NexuSync what to build, the same way you would prompt your coding agent. Attach documents, sync the repository, and pull in customer evidence from PMF studies, so the plan starts grounded in your product instead of a guess.

02

Compile it to a spec

NexuSync drafts a PRD for your approval, writes EARS-format requirements, and expands them into a dependency-aware plan of themes, epics, stories, and tasks. You choose the scope, from Simple to Exhaustive.

WHEN a request exceeds its quota, THE SYSTEM SHALL return 429 with a Retry-After header.

REQ-042

WHILE a key is suspended, THE SYSTEM SHALL reject new sessions and log the attempt.

Agents execute over MCP

Cursor, Claude Code, and Copilot connect to the NexuSync MCP server, pull the next story with its acceptance criteria, build it, and report progress back. The sprint board, roadmap, and metrics update as the work lands.
