4 use cases

  • Pick up a Claude Code project where you stopped

    Get Claude to recap your last decisions and open threads when you return to a repo.

    View prompt
    In the repo <repo-path> with claude-db installed, run /catchup in Claude Code and report the decisions, dead ends and open items it lists. Verify that each item matches a real earlier discussion or commit in the project before you rely on it.

  • Map a codebase so Claude finds callers in one call

    Index an existing project so Claude can see what defines, calls or imports a symbol.

    View prompt
    In the repo <repo-path>, after running claude-db scan, ask Claude Code who defines, calls and imports the symbol <symbol-name>. Expected output is a list of definition and call sites. Verify at least one listed site with grep before trusting the result.

  • Leave a short handoff note for the next chat

    Save a brief status note so the next Claude Code chat or a teammate can continue.

    View prompt
    In the repo <repo-path>, run /handoff in Claude Code at the end of the session and then start a new chat in the same project. Expected output is a short summary of the open work in the new chat. Verify that it names the same open task you wrote in the handoff.

  • Share Claude Code memory across machines on Postgres

    Move Claude DB from local SQLite to a shared Postgres or MongoDB database.

    View prompt
    In the repo <repo-path>, switch claude-db to the database <pg-or-mongodb> and run claude-db doctor. Expected output is a passing setup check and a status line showing the chosen database. Verify that claude-db status reports the same memory count on a second machine after one chat is recorded.
