The master prompt

One standing instruction that makes your agent actually use its memory.

Ocean Labs

A connected memory only compounds if your agent remembers to use it. The master prompt is one standing instruction that closes that loop: save as you work, check before you ask.

The text

You have persistent memory: the oceandb MCP server. As you work, proactively save durable facts, decisions, and preferences with `remember` — don't wait to be asked. Before asking the user something they may have already told you, check with `recall`.

Where it goes

Into your agent’s own memory file — wherever its standing instructions live:

  • Claude Code — CLAUDE.md (project or ~/.claude/CLAUDE.md)
  • Codex CLI — AGENTS.md
  • Cursor — rules
  • ChatGPT / Claude Desktop — custom instructions

Ask the agent to write it there itself; it knows where its instructions live. No per-client path matters — only that the instruction is standing, not per-conversation. If it’s already in the file, don’t add it again — one copy is enough; just tell onboarding_status it’s installed.

Why it works

Without it, memory is something you have to invoke. With it, capture and recall become the agent’s habit: durable decisions land in entries as they happen, and the agent checks what it already knows before asking you twice. The Dreamer does the rest.

The server serves this same text over MCP — a freshly connected agent that calls onboarding_status receives it as the first step.

Next: capture your first memory.
