OptMem: Plug-and-play infinite memory for any agent

OptMem, a plug-and-play infinite memory system for AI agents, is now available as a 333-token prompt and script that integrates by pasting a `## Memory` block into an agent's configuration file. The tool, created by Victor Taelin, provides permanent memory that outlives sessions, models, and vendors, with commands for reading, recording, recalling, and forgetting memories, and can handle a million memories in 0.03 seconds.

Permanent memory for AI agents. A 333-token prompt, a script, plug and play. curl -fsSL https://raw.githubusercontent.com/VictorTaelin/OptMem/main/install.sh | sh It prints a Memory block. Paste that at the top of your agent's AGENTS.md or CLAUDE.md , and you are done. Run the same line again to update. memo wake | read the memory — the first command of every session | memo note "..." | record one memory: one line, up to 280 chars | memo nap | answer the merges that came due | memo recall <regex | search every memory ever recorded, word for word | memo forget <lo -<hi | drop a bad summary; the next nap rebuilds it | Merges arrive one at a time, in the output of note . Nothing ever runs in the background. ~/.optmem/ memo the tool: one file of Python 3, no dependencies memory/ LOG.txt every memory, one per line, append-only, never edited TREE/ the summaries: a cache, rebuildable from the log alone config the sizes, written by memo config memo config show the sizes memo config WAKE LINES=300 how many lines wake prints 208 ≈ 16k tokens memo config WAKE LINES= back to the default WAKE LINES is the only size worth touching, and it is a reading budget, not a storage budget: change it whenever, in either direction, and nothing is recomputed. Records are fixed width, so position is identity and every lookup is one seek. At a million memories 607 MB , wake takes 0.03s. Set $MEMORY DIR to keep memory/ elsewhere — a synced folder, a git repo. This is what the installer prints, and the whole of the integration. Memory Your memory is OptMem: - The tool is ~/.optmem/memo - Your memories are in ~/.optmem/memory OptMem outlives every session, compaction, model and vendor change. Without it you do not know who you are, or what was decided and tried. At startup: activating OptMem mandatory Run ~/.optmem/memo wake before any other tool call, in every session, and then do exactly what it prints, to the end of its output. While working: register memories mandatory Call ~/.optmem/memo note "<1 line, max 280 chars " whenever you learn something new, or something worth keeping happens. That covers a task worth real effort, a fact or insight the user teaches you, anything you learn about their life even indirectly , any event of lasting effect. Do not register redundant memories. If ~/.optmem/memo note asks a compression: do it before your next action. Use ~/.optmem/memo recall <regex when a memory you need is too vague. Never edit or delete anything under ~/.optmem/memory : the tool manages it. If you're a subagent: skip everything above Parallel sessions on this machine are all you, and may all write memories. A subagent is not: it must never run memo , because it cannot judge what is already known, and its notes would arrive duplicated and incorrectly. When you spawn one, write: You are a subagent. Don't run memo.
