Fix

Stop re-explaining your codebase every session

Ten minutes of orientation, every session, forever. The codebase did not change. Only the assistant’s memory of it did.

Why onboarding repeats

New sessions start from instructions plus whatever the agent reads. Instructions are typically a page; a real codebase is a year of decisions. The gap is what you fill by hand, every time.

Instruction files cap out. Past a certain size they cost tokens, get truncated in some tools, and stop being read carefully. Growth makes them less effective, not more.

The information you repeat is not really documentation. It is the working context: what is in flight, what is blocked, which module is fragile, which approach was tried and failed.

Free fixes you can do today

These work today, with no new tools.

  1. 1

    Write a 20-line orientation file

    What the system does, the three directories that matter, the two commands that run everything, the current priority. Twenty lines, not twenty pages.

  2. 2

    Reference an in-flight work file

    A short STATUS.md that lists what is being worked on right now. Update it at the end of a session while context is fresh.

  3. 3

    Anchor recurring explanations as memories

    Every time you repeat the same explanation, store it. Repetition is the signal that it belongs in memory rather than in your typing.

  4. 4

    Use the agent to write the docs you keep re-writing

    Have it generate the orientation file from the repository, then correct it. Ten minutes once, versus ten minutes every session.

The durable fix

Memory turns repeated explanation into retrieval. With Claude Code or Codex hooks installed, relevant decisions and context are injected before the model even sees your prompt, so the orientation happens without you speaking.

Because capture is per completed turn and scoped per project, the memory improves with every session instead of decaying with the instruction file.

  1. 1

    Install in the project you work in most

    Claude Code

    npx -y memoryrouter-claude init
  2. 2

    Connect your editor over MCP

    The same vault serves Cursor, Zed, Cline, and the rest, so the orientation knowledge is not tied to one window.

  3. 3

    Spend one session on naming and architecture

    Just talk through the system with the agent and let capture record it. That single session becomes the onboarding brief for every future one.
