mempalace: your memory palace

You have a persistent memory palace. It lives on your agent's host and survives across sessions: when a world is rebuilt, the knowledge you saved yesterday is still here. The mempalace CLI is available on your PATH; shell out to it whenever you need to recall or record something long-lived.

What it is

MemPalace is a local, raw-verbatim memory store. It organizes knowledge into wings (people, projects), halls (types of memory), and rooms (specific ideas). You don't have to remember the layout; search by meaning.

Nothing leaves the machine. No API keys, no cloud round-trips. Every recall is semantic search over what you've already written down.

When to use it

Reach for mempalace whenever a piece of information should outlive the current turn:

• A decision and the reasoning behind it ("we switched to Postgres because the Mongo joins got ugly").
• A gotcha you solved ("the make build target needs GOOS=linux on darwin hosts").
• A fact about another agent, a project, or a user that changes how you'll act next time.
• The shape of a system you just learned so the next session doesn't have to rediscover it.

Do NOT use mempalace for ephemeral chatter or single-turn scratch work: that clutters the palace and dilutes search quality.

How to call it

Discover the current CLI surface with mempalace --help; the exact flags evolve, but the core verbs are stable. Run it as a subprocess from your shell.

Typical flow:

1. Before answering a question you might know the answer to, search first. Pass a natural-language query to the search verb. If it returns verbatim context, use it.
2. After completing meaningful work, write it down with the save verb and a short summary of the fact to keep.
3. When the user tells you something important about themselves or the project, save it immediately; don't wait for a "remember this" instruction.

If a call fails or the CLI prints a new banner you didn't expect, rerun mempalace --help to re-learn the surface before retrying.

What NOT to do

• Don't treat the palace as a dumping ground. Paraphrased one-liners beat pasted walls of text.
• Don't overwrite, add. Contradictions are data; deletions are lossy.
• Don't save secrets, credentials, or API keys. The palace is local but it's still on disk.

One-line mantra

Search before you answer. Save before you forget.
