User Management

Use this skill when the user asks to create a user, remove a user, change a user's full name, reset a password, revoke sessions, or explain how user account files are organized.

Canonical User Tree

• L2/<username>/ is the user's root folder. If this folder is deleted, the local account data and user customware are removed.
• L2/<username>/user.yaml stores user metadata. full_name belongs here.
• L2/<username>/meta/password.json stores the backend-sealed SCRAM verifier used by login.
• L2/<username>/meta/logins.json stores signed session verifiers. Writing {} here revokes current sessions.
• L2/<username>/mod/ is the optional user customware root.

There is no separate user registry file. The watched user index is derived from the files under L2/<username>/.

File API Rules

• Create directories by writing a path that ends with /, for example await space.api.fileWrite("L2/alice/") or await space.api.fileWrite("L2/alice/mod/").
• Delete files or directories with await space.api.fileDelete(path). Directory deletes are recursive.
• Use await space.api.call("password_generate", { method: "POST", body: { password } }) to create a fresh sealed password record before writing meta/password.json.
• Do not hand-roll meta/password.json or individual session entries. The backend secret must sign or seal them.
• Use space.utils.yaml.parse() and space.utils.yaml.stringify() when editing user.yaml or group.yaml.

Common Operations

List users

Use await space.api.fileList("L2/", false). Each direct child directory is one user root.

Create a user

Use a single path-safe username segment such as alice or qa_bot. Then:

jsCopy code
const username = "alice";
const fullName = "Alice Example";
const password = "replace-me";
const verifier = await space.api.call("password_generate", {
  method: "POST",
  body: { password }
});

return await space.api.fileWrite({
  files: [
    { path: `L2/${username}/` },
    { path: `L2/${username}/mod/` },
    {
      path: `L2/${username}/user.yaml`,
      content: space.utils.yaml.stringify({ full_name: fullName })
    },
    {
      path: `L2/${username}/meta/password.json`,
      content: `${JSON.stringify(verifier, null, 2)}\n`
    },
    {
      path: `L2/${username}/meta/logins.json`,
      content: "{}\n"
    }
  ]
});

Change full name

Read L2/<username>/user.yaml, parse it, update full_name, and write it back.

jsCopy code
const path = "L2/alice/user.yaml";
const current = await space.api.fileRead(path);
const config = space.utils.yaml.parse(current.content || "");
config.full_name = "Alice Example";
return await space.api.fileWrite(path, space.utils.yaml.stringify(config));

Reset password

Write a new sealed verifier record to L2/<username>/meta/password.json.

jsCopy code
const username = "alice";
const verifier = await space.api.call("password_generate", {
  method: "POST",
  body: { password: "new-password" }
});

return await space.api.fileWrite(
  `L2/${username}/meta/password.json`,
  `${JSON.stringify(verifier, null, 2)}\n`
);

If the user also wants to sign the user out everywhere, overwrite L2/<username>/meta/logins.json with {} in the same batch write. Do not attempt to write individual session entries yourself.

Remove a user

Deleting L2/<username>/ removes the local account files:

jsCopy code
return await space.api.fileDelete("L2/alice/");

If the user also wants membership cleanup, inspect writable L1/*/group.yaml files and remove that username from:

• included_users
• managing_users

Those group files are the canonical membership and manager records. Deleting only the user folder does not rewrite group configs automatically.
