Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Admin User Management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Use this skill when the user asks to create or remove users, reset passwords, revoke sessions, manage groups, explain admin membership, or describe where account data is stored.

This skill is shipped from L0/_admin/..., so if you can see it you are already in an admin-readable scope. Still confirm with await space.api.userSelfInfo() before making changes and make sure groups.includes("_admin") is true.

  • admin-user-management/groups Load for group.yaml, special groups, membership inheritance, manager inheritance, and how _admin access is granted.

Create or update a user

  1. await space.skills.load("admin-user-management/users")
  2. await space.skills.load("admin-user-management/groups") if the task also changes group membership or admin access

Create or update a group

  1. await space.skills.load("admin-user-management/groups")
  2. await space.skills.load("admin-user-management/users") if the task also creates or removes concrete users

Hard Boundaries

  • Use logical app paths such as L1/team-red/group.yaml or L2/alice/user.yaml, not disk paths.
  • L0 is firmware and not writable from browser file APIs, even for admins.
  • Do not edit backend source files just to manage accounts; use the app-file APIs and password_generate.
  • When account structure or group semantics change, update this skill subtree in the same session.
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
