User Management

User Management is a skill for Claude Code, Codex from binary16labs/prime-silo. It costs 24 tokens per session (945 once invoked), scanned A, a copy of User Management, MIT.

A user-account management skill based on canonical files under `L2/<username>/`. It treats user metadata, password records, login sessions, and group memberships as file-backed account data.

In plain words
What is it for?
Creating or removing users, changing names, resetting passwords, revoking sessions, and managing related group membership files.
Why use it?
It provides a defined way to change accounts while keeping the user files and access state consistent.

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

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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:

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"
    }
  ]
});

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.
