4 use cases

  • Set up persistent project memory for a repo in Codex

    Install the EchoesVault plugin and initialize memory in one project so Codex keeps context between tasks.

    View prompt
    Using the EchoesVault plugin from psinetron/echoes-vault-codex, initialize project memory in <project-path> and list the files it created. Expected output: an EchoesVault/ folder and a .echoes-vault/ folder containing echoes_vault.py. Verify that EchoesVault/.gitignore ignores index.md.

  • Share one project memory across teammates and agents

    Commit the EchoesVault files so teammates and Claude or OpenCode follow the same memory rules.

    View prompt
    In the project at <project-path>, use the committed EchoesVault files from psinetron/echoes-vault-codex to restore project memory with Claude or OpenCode. Expected output: a short summary of the latest session entries and the protocol version. Verify that the agent reads EchoesVault/AGENT_PROTOCOL.md before writing.

  • Bootstrap a project's memory from the terminal

    Run the bundled engine directly to create EchoesVault files in a project without opening Codex.

    View prompt
    Clone psinetron/echoes-vault-codex and run its scripts/echoes_vault.py init against <project-path> with --agent codex and --adapter-version 1.1.1. Expected output: the EchoesVault/ and .echoes-vault/ folders in that project. Verify that .echoes-vault/echoes_vault.py exists in the target project.

  • Restore project memory at task start and save it at the end

    Use the status, restore, and final save commands in Codex to carry context from one task to the next.

    View prompt
    In the initialized project at <project-path>, restore EchoesVault memory in Codex, show the status, and then save the session. Expected output: the restored index with the three latest session entries, a status summary, and a saved session file. Verify that the status reports no index integrity problems.
