wterm

wterm is a skill for Claude Code from tdimino/claude-code-minoan. It costs 76 tokens per session (686 once invoked), scanned A, original, MIT.

A tool for running shell sessions through a web browser, either on the local machine or across a private network. It can create, list, monitor, restart, and stop terminal sessions.

In plain words
What is it for?
Use it to open a browser-based terminal, start a shell or Claude Code session, inspect active sessions, terminate a session, or restart the web terminal service.
Why use it?
It lets you access command-line work without being at the machine's terminal. Session and daemon controls make it easier to manage remote shells and running processes.

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

wterm 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.

The scan reads SKILL.md. This mod also ships 6 executable files (launchd/install.sh, scripts/create-session.sh, scripts/kill-session.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

wterm

Manage the wterm-server daemon — a Node.js service providing browser-based shell access via @wterm/react + node-pty. Access locally at https://wterm.localhost (via portless) or remotely from any tailnet device at http://<hostname>:3036.

Commands

Check status

bash ~/.claude/skills/wterm/scripts/status.sh

Reports whether the daemon is running, its PID, port, and active session count.

List sessions

bash ~/.claude/skills/wterm/scripts/list-sessions.sh

Shows all active PTY sessions (id, name, command, PID, client count, last activity).

Create a session

bash ~/.claude/skills/wterm/scripts/create-session.sh           # default: zsh
bash ~/.claude/skills/wterm/scripts/create-session.sh claude     # Claude Code
bash ~/.claude/skills/wterm/scripts/create-session.sh /bin/bash  # explicit shell

Spawns a new PTY session. Default shell is zsh. Pass claude to start a Claude Code session.

Kill a session

bash ~/.claude/skills/wterm/scripts/kill-session.sh <session-id>

Terminates a session by its hex ID (get IDs from list-sessions.sh).

Restart the daemon

bash ~/.claude/skills/wterm/scripts/restart.sh

Restarts the wterm-server LaunchAgent. All active sessions are lost.

Architecture

  • Daemon: ~/daimones/wterm-server/ — TypeScript, node-pty, ws, Vite React SPA
  • Port: 3036 (bound to 0.0.0.0 for Tailscale access)
  • Auth: Bearer token from WTERM_AUTH_TOKEN in ~/.config/env/secrets.env. Auth is fail-closed — server rejects all requests if no token is configured.
  • LaunchAgent: com.minoan.wterm-server — RunAtLoad, KeepAlive
  • Logs: ~/.claude/logs/wterm-server.{out,err}.log

Gotchas

  • Sessions default to zsh, not Claude Code. Pass claude explicitly to create-session.sh.
  • The daemon must be running on the host machine. If status shows not running, use restart.sh or check launchctl list | grep wterm.
  • Auth token is required for remote access. If scripts return 401, verify WTERM_AUTH_TOKEN is set in ~/.config/env/secrets.env.
  • Restarting the daemon kills all active sessions — the scrollback buffer is in-memory only.

What ships with it

7 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.
