Admin Groups

Use this skill for group creation, membership changes, manager changes, or explaining how _all and _admin work.

Canonical Group Tree

• Runtime-managed groups live under L1/<group>/.
• L1/<group>/group.yaml is the canonical membership and manager file.
• L1/<group>/mod/ is that group's customware module root.

Do not write group membership into arbitrary files. group.yaml is the contract.

Special Groups

• _all is the implicit everyone group.
• Do not create or rely on L1/_all/group.yaml for membership. _all membership is universal, not file-driven.
• _admin is the admin group.
• Adding a user or included group to _admin makes those users admins.

Canonical group.yaml Fields

• included_users
• included_groups
• managing_users
• managing_groups

Meaning:

• included_users: direct members of the group
• included_groups: groups whose members also become members of this group
• managing_users: users who may write this group's L1/<group>/ tree
• managing_groups: groups whose members may write this group's L1/<group>/ tree

Manager inheritance is separate from membership inheritance. Do not treat included_* as manager fields or vice versa.

Create A Group

Runtime-created groups belong in L1, not L0.

const groupId = "team-red";

return await space.api.fileWrite({
  files: [
    { path: `L1/${groupId}/` },
    { path: `L1/${groupId}/mod/` },
    {
      path: `L1/${groupId}/group.yaml`,
      content: space.utils.yaml.stringify({
        included_groups: [],
        included_users: [],
        managing_groups: [],
        managing_users: []
      })
    }
  ]
});

Update Membership Or Managers

Read, parse, normalize, then write group.yaml.

const path = "L1/team-red/group.yaml";
const current = await space.api.fileRead(path);
const config = space.utils.yaml.parse(current.content || "");

config.included_users = [...new Set([...(config.included_users || []), "alice"])].sort();
config.managing_users = [...new Set([...(config.managing_users || []), "alice"])].sort();

return await space.api.fileWrite(path, space.utils.yaml.stringify(config));

Use the same pattern for included_groups and managing_groups.

Grant Or Remove Admin Access

The canonical way to grant admin access is to edit L1/_admin/group.yaml:

• add usernames to included_users
• or add groups to included_groups

Example:

const path = "L1/_admin/group.yaml";
const current = await space.api.fileRead(path);
const config = space.utils.yaml.parse(current.content || "");
config.included_users = [...new Set([...(config.included_users || []), "alice"])].sort();
return await space.api.fileWrite(path, space.utils.yaml.stringify(config));

Mental Model

• membership answers "which users belong to this group?"
• manager lists answer "which users may write this group's L1 tree?"
• _admin membership is stronger than ordinary group management because admins may write any L1/* and L2/*
• _all is readable by everyone, but it is not the place to store membership rules

CLI Reference

Backend equivalents exist for operators outside the browser:

• node space group create <group-id>
• node space group add <group-id> <user|group> <id> [--manager]
• node space group remove <group-id> <user|group> <id> [--manager]

From the overlay agent, prefer logical app-file edits through space.api.
