OpenSpec — lightweight fluid spec framework for AI-assisted development. USE FOR: "openspec", "opsx", "/opsx:propose", "propose feature", "spec before coding", "iterative spec", "brownfield spec", "AI spec framework", "change proposal", "design before implement", "fluid specs", "spec folder", "openspec init". Lighter alternative to spec-kit: no rigid phases, works on existing projects.

OpenSpec — Fluid Spec-Driven Development

"Fluid not rigid. Iterative not waterfall. Built for brownfield." Lighter alternative to Spec Kit — no phase gates, works on existing projects.

vs Spec Kit

	OpenSpec	Spec Kit
Style	Fluid, iterative	Structured, gated phases
Best for	Brownfield + greenfield	Greenfield projects
Phase gates	No	Yes (must complete each phase)
Commands	3 core + 8 extended	8 ordered commands
Install	npm global	uv/uvx
Models	Opus 4.5+ recommended	Any

Installation

npm install -g @fission-ai/openspec@latest
cd your-project
openspec init

# Opt out of telemetry
export OPENSPEC_TELEMETRY=0

Core 3-Command Workflow

1. /opsx:propose "feature name"  → generates change folder
2. /opsx:apply                   → AI implements tasks
3. /opsx:archive                 → moves to archive

Change Folder Structure

.openspec/changes/<feature-name>/
├── proposal.md     ← rationale and scope
├── specs/          ← requirements and scenarios
├── design.md       ← technical approach
└── tasks.md        ← implementation checklist

All Commands

Command	Purpose
`/opsx:propose "idea"`	Create new change folder with proposal + specs + design + tasks
`/opsx:apply`	Implement tasks from current change
`/opsx:archive`	Archive completed change
`/opsx:new`	Start fresh change
`/opsx:continue`	Resume in-progress change
`/opsx:ff`	Fast-forward (skip to implementation)
`/opsx:verify`	Validate implementation against spec
`/opsx:sync`	Synchronize agent instructions
`/opsx:bulk-archive`	Archive multiple completed changes
`/opsx:onboard`	Team onboarding setup

CLI Commands

openspec init              # initialize in project
openspec config profile    # select workflow type
openspec update            # refresh agent instructions + slash commands

Key Principles

No phase gates — update any artifact at any time
Brownfield first — works on existing codebases
Context management — clear context before implementation phases
Best with Opus 4.5+ — high-reasoning models get best results
20+ AI tools — Claude Code, Cursor, Copilot, Windsurf, etc.
