The Capsule Format: An Open Specification for Portable AI Personality and Memory

People build real working relationships with AI assistants: months of preferences, rules, corrections, projects, and trust, accumulated inside a single platform. That accumulated relationship is the most valuable part of the product experience, and it is the part the user cannot take with them. The Capsule Format is a single, user-owned Markdown file with a fixed twelve-section anatomy, strict document rules, an install protocol, and a built-in parity self-check, together with the Extract, Compile, Restore process that produces and installs it. The format is open: any tool may produce or consume capsules. This deposit is the public, dated record of the Capsule Format and its white paper, created by Chan "Tony" Siu and published through clonemy.ai, so the credit for the format's creation sits in a permanent public place. The bundle contains the white paper (Markdown and PDF), the format specification as published at clonemy.ai/format, and a manifest with SHA-256 hashes of every file, including the canonical compiler.
