What Is Sequant

Sequant is workflow automation for Claude Code. It turns GitHub issues into merge-ready pull requests through structured phases and quality gates.

You write issues. Sequant plans, builds, tests, and reviews them — each step with guardrails that catch problems before they reach your codebase.

The Problem

Claude Code is remarkably capable. Give it a well-scoped issue and it can plan, implement, and test a feature in minutes. But capability alone doesn’t guarantee consistency.

Without structure, AI-assisted development has a “results may vary” quality:

A vague issue produces a vague implementation
There’s no formal review step — code goes from “written” to “done”
Context accumulates over long sessions, drifting from the original goal
There’s nothing tracking which issues are planned, in progress, or reviewed
Each session starts from scratch with no memory of prior work

These aren’t flaws in Claude Code. They’re the natural consequence of working without a process. Human developers solve this with methodologies, code review, CI/CD, and project management. AI-assisted development needs the same discipline.

Sequant provides that discipline.

How It Works

Sequant installs slash commands into Claude Code that enforce a phased workflow. Each issue moves through plan, build, and review — with an isolated worktree keeping your main branch clean and a quality loop that catches problems before merge.

Or run the full pipeline in one command:

/fullsolve 123

Quick Start

npm install sequant
npx sequant init
npx sequant doctor

Then in Claude Code:

/fullsolve 123
