Business, tech, systems thinking, and the occasional rant.
I manage a group of companies in Barcelona — legal, accounting, property management. I also build tools, mostly for making AI agents useful in real workflows.
- Odoo CLI — Command-line interface for Odoo ERP. Records, mail, modules, schema, accounting — from the terminal.
npm install -g @marcfargas/odoo-cli - Odoo Toolbox — Progressive skill modules that teach AI agents the Odoo API. CI-tested against real v17 and v18 instances. Includes TypeScript RPC client and schema introspection.
Extensions for pi, an AI coding agent CLI:
- Pi PowerShell — Windows system integration and background processes (solves the Git Bash
&hang) - Pi Heartbeat — Non-blocking timers and heartbeats — stop using
sleep - Pi TRAMP — Transparent remote execution via SSH/Docker — pi stays local, tools run remotely
- Pi Planner — Plan-then-execute workflow with safety classifications
- Pi Server — Detachable agent sessions — headless daemon + terminal client over WebSocket
- Pi Devcontainers — Launch dev containers with pi pre-installed
- Go Easy — Unified CLI for Gmail, Drive, Calendar, and Tasks. Google APIs without the pain.
- Go MAPI — Right-click → "Send to Mail recipient" → opens in Gmail. Zero config Windows MAPI bridge.
- Skills — Reusable skills for AI coding agents (pi, Claude Code, Agent Skills standard)
- Holdpty — Minimal cross-platform detached PTY. Launch in a real terminal, attach later.
