ChatPRD plugin
One plugin package for ChatGPT, Codex, and Cursor. Product requirements where you work. Write PRDs from code context, implement from specs, verify alignment, and keep docs in sync — powered by ChatPRD.
What's included
MCP Server — Zero-config connection to ChatPRD. No API key needed. ChatPRD's built-in templates (PRD, AI development brief, user testing plan, launch checklist) work without an account; connect a ChatPRD account to access your documents, projects, templates, and team workspace.
Skills:
| Skill | What it does |
|---|
get-started | Onboarding: confirms the ChatPRD connection and suggests a first task |
write-prd | Writes a PRD from notes, a feature idea, or codebase context — as Markdown or in a connected doc tool without an account, or in ChatPRD when connected |
review-doc | ChatPRD's "Review my doc": a strategy-first scorecard (strategy, structure, clarity, completeness) with exact, quotable edit suggestions — no account needed for pasted docs |
doc-to-artifact | Turns a PRD or doc into a self-contained interactive HTML page with inline diagrams and clickable prototypes |
implement-from-prd | Fetches a PRD and builds an implementation plan using plan mode |
check-prd-alignment | Diffs your branch against a PRD — reports coverage, gaps, and Opportunity items to better achieve the PRD's goals |
update-prd | Updates a PRD with new decisions or what was actually built, including deviations and trade-offs |
Rule — Always-on product-aware development standards: reference specs, handle edge cases, flag deviations.
Agent — Product reviewer that checks code changes against PRD requirements, not just technical correctness.
How it works
The plugin saves local copies of PRDs to a prd/ directory in your project root. These are committed to the repo so the whole team has specs alongside the code — useful for code review, onboarding, and understanding why things were built a certain way. ChatPRD remains the source of truth; local copies are kept in sync by the update-prd skill.
When you run implement-from-prd, Cursor enters plan mode to build a structured implementation plan before writing any code. Every PRD requirement maps to a milestone so nothing gets missed.
The check-prd-alignment skill goes beyond a checkbox exercise — it reads the PRD's stated user and business goals and identifies Opportunity items where the implementation could better achieve those goals.
Package layout
The repo root is an Agent Plugins package:
plugin.json — portable manifest. OpenAI listing, onboarding, and review metadata live in extensions.com.openai.mcp.json — the ChatPRD remote MCP server (https://app.chatprd.ai/mcp). Template tools are public; account tools use OAuth.skills/ — shared by ChatGPT, Codex, and Cursor.assets/ — icons..cursor-plugin/plugin.json, rules/, agents/ — Cursor-only components..agents/plugins/marketplace.json — Codex / ChatGPT desktop marketplace for installing from this repo.
Getting started
Cursor: Install the ChatPRD plugin from the Cursor Marketplace, open a project, and try "Write a PRD for [feature]".
Codex / ChatGPT desktop:
codex plugin marketplace add ChatPRD/cursor-plugin
codex plugin add chatprd@chatprd
Then connect your ChatPRD account when prompted and try "Review my latest ChatPRD document".
Submitting to the ChatGPT plugin directory
./scripts/package-openai.sh # writes dist/chatprd-<version>.zip
Upload the ZIP in the OpenAI plugin submission portal. Reviewer credentials and the demo recording URL are entered in the dashboard, not in the package. Bump version in plugin.json for each new upload.
