magic-compact

Lossless context compression for OpenCode and Claude Code.

OpenCode and Claude Code's built-in compaction replaces an entire conversation with one summary blob. The user messages, the assistant's reasoning, tool calls, design decisions, and workflow are all flattened into a generic template (Goal, Progress, Key Decisions...). The agent wakes up with amnesia, forced to reconstruct its working state from an abstraction that captured a fraction of what mattered.

Magic Compact takes a different approach: preserve the conversation skeleton, condense each old assistant turn into its own summary, prune bulky tool I/O, and keep everything retrievable. The agent retains its memory of what it did, why, and what comes next.
