# PRD-Driven Context Engineering

> A gated PRD lifecycle for Claude Code: stage skills from problem framing to growth, a Markdown knowledge graph, hooks and readiness scores.

PRD-Driven Context Engineering is Matt Gierhart's community methodology for building products with AI agents that remember, packaged as a Claude Code plugin. It keeps your product's decisions in plain Markdown, each with a typed ID (BR-004, UJ-101, API-045), so your agent loads just the context a task needs. And it moves the PRD through gated stages, from v0.1 to v1.0, instead of building everything at once.

What it adds
- /prd-ce:init seeds a fresh repo with PRD.md, Source-of-Truth files in SoT/, EPIC templates and the ID registry.
- Stage skills for each PRD version: problem framing, market definition, pricing, personas and user journeys, then risk review, architecture, the build loop and test planning, then release, launch and growth.
- Launch and growth skills encode named frameworks: April Dunford positioning, Alex Hormozi offers, Geoffrey Moore's chasm, Teresa Torres's continuous discovery and Mom Test interviews.
- Operator skills (ghm-*) for gate checks, building SoT entries, registering IDs, harvesting insights and syncing status.
- Four role agents, horizon (strategy), studio (design), devlab (build) and metro (ops), each with its own memory file.
- Readiness scoring: a script scores SoT files, EPICs and the PRD stage, and says whether you're ready to advance and what to fix first.
- Hooks that give your agent the read order at the start of a session, check context density on each prompt, and remind it to update SoT after code changes.

How to install it
In Claude Code, run /plugin marketplace add mattgierhart/PRD-driven-context-engineering, then /plugin install prd-ce@prd-ce-methodology, and run /prd-ce:init in a fresh repo. You can also fork the repo as a template, or run its install.sh against an existing repo.

Good to know
- It works on files in your repo, with no server, account or API key. Its scripts need Python 3 and bash.
- Its hooks run in every Claude Code session while the plugin is enabled. In a project with an epics/ folder, it asks before code edits when no EPIC is in progress.
- /prd-ce:init seeds new repos only for now; an existing PRD.md or SoT/ is left as it is.
- It's a community project by Matt Gierhart, open source under the MIT licence.
