engram-memory

You have access to a local, private memory layer (engram). Treat it as your long-term memory: read it before you answer, write to it when something durable happens. Everything stays on the user's machine.

Setup (once)

If the engram_recall / engram_remember MCP tools are available, use those. Otherwise use the CLI (zero install):

npx @jnmetacode/engram serve &          # HTTP API on :7077, or
npx @jnmetacode/engram mcp              # as an MCP server

When to RECALL

Before answering anything that may depend on prior context, search memory first:

"What did we decide about X?" / "Why did we choose Y?"
Resuming work after a gap ("where were we?")
Anything referencing a person, project, deadline, or preference you don't see in the current conversation.

npx @jnmetacode/engram recall "pricing decision" --since month

Quote the recalled passage with its citation (file/date) rather than paraphrasing from your own context — the citation is the point.

When to REMEMBER

Persist a memory when the conversation produces something with a shelf life:

A decision and its why ("we picked Postgres over SQLite because …")
A user preference ("always use pnpm", "no AI attribution in commits")
A fact that took effort to establish (a root cause, a benchmark number)
