PCA — Git for AI context

PCA is a local-first CLI that keeps project context, decisions, and AI handoff notes close to your code. It solves context drift between Git changes and AI agents.

Builders using AI agents (Cursor, Claude, Codex, Gemini) lose project context between sessions. You repeat yourself. The agent forgets decisions. Prompts grow. PCA fixes that.

Install

npm install -g @quantpartners/pca

Requires Node.js >= 20.

Quick start

cd your-project
pca setup
pca init
pca bootstrap
pca context

pca setup configures mode and API key. pca init initializes project memory. pca bootstrap fills project context interactively. pca context generates the current project context, copies it to your clipboard, and saves .pca/last-context.md.

Commands

CORE

GIT SYNC (automatic)

Hooks run automatically on git commit, checkout, merge and rebase. No manual commands needed.

How it works

• Markdown files hold project memory and agent-facing context.
• SQLite in .pca/pca.db stores context commits, staged items, branches, and status.
• Git hooks stage context from commits and track branch, merge, and rebase events.
• pca context builds a paste-ready Markdown snapshot for your AI agent.

Git sync

pca init installs hooks for commit, checkout, merge, and rewrite/rebase events. The hooks stage context automatically, switch branch-local context, and archive old branch context when confirmed. Use pca staged list, pca staged commit, pca staged drop <index>, or pca staged clear to manage staged context.
