Spectre — Productivity skill for Claude Code

SPECTRE: A Workflow for Product Builders

SPECTRE is an Agentic Engineering workflow for Claude Code and Codex designed to help you do ONE THING more, faster, and with higher quality.

**🚀 Ship Product Features**

SPECTRE's workflow covers the complete software development lifecycle - from scoping a feature, finalizing user flows, writing the technical design, generating tasks, executing the tasks, code review, validating and proving the work works, cleaning up, testing, shipping, and generating durable & retrievable knowledge your Agent can find and load when relevant.

It has been tested on brand new codebases and codebases with hundreds of thousands of lines of code. Its been tested building websites, react native apps, native desktop apps, and personal software.

**SPECTRE helps you get higher quality and more consistent results from your coding agent, while they work autonomously for much longer, so 10-100x'ing your typical output feels *easy* and more importantly, *repeatable.***


⚡ Quick Start

Within Claude Code

# Add marketplace and install
claude plugin marketplace add joenandez/spectre
claude plugin install spectre@spectre

Then start building:

/spectre:scope

That's it. You just start with 1 command to build features.

Within Codex

codex plugin marketplace add joenandez/spectre
codex plugin add spectre@spectre

Restart or open a new Codex session after install so managed custom agents can be discovered. Plugin hooks still require Codex trust review.

Then run a Spectre command such as:

$spectre-scope


🔁 How It Works

All feature work enters through Scope and continues through the adaptive Plan, regardless of the size of the feature.

You really only need to remember `/spectre:scope`; every final agent response guides you to what
