saipen

saipen is a cross-agent continuity protocol and project management system. It lets any AI agent pick up exactly where another left off, with zero context loss.

Core concept

A persistent .saipen/ directory at the project root stores all state (STATE.md), board (BOARD.md), log (LOG.md), and phase progress. Any agent with filesystem access reads this directory and continues work without asking "what were we doing?"

Key features:

• Agent-agnostic — works with Claude, Gemini, Codex, Aider, any agent that reads markdown files
• Portable — pure markdown, zero dependencies, one directory
• Phase-driven — structured workflow: PLAN → SCOUT → BUILD → VERIFY → REVIEW → SHIP → DONE
• Goal mode — multi-wave execution with ticket caps for focused sprints
• SubSaipen — delegatable sub-agents with read-only sandboxed roles
• Multi-platform — Linux, macOS, Windows (PowerShell + bash bootstrap)
