thurbox: Skill for Claude Code

.agents/skills/thurbox-cli/SKILL.md

thurbox-cli is a skill for Claude Code, Codex from Thurbeen/thurbox. It costs 0 tokens per session (18,613 once invoked), scanned A, original, MIT.

A command-line tool for creating and managing coding-agent sessions, tasks, messages, editors, settings, extensions, and plugins. It can run sessions locally or on remote hosts and organize lead and worker sessions.

In plain words
What is it for?
Use it to start sessions, attach repositories, create tasks, send messages, manage session hooks, and control agent-related configuration from scripts or a terminal.
Why use it?
It lets developers control agent work without opening the terminal user interface. Shared session storage and messaging make it easier to coordinate work across repositories and agents.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; mentions Claude Code; installed under .agents/ (shared by several agents).

This is Thurbeen/thurbox's own configuration. It tells Claude Code and Codex how to work on thurbox itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything thurbox configures →

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • medium Tool Misuse · line 139
    Tool defaults are unsafe or overly permissive (e.g. disabled TLS verification, no authentication, world-writable permissions). Unsafe defaults widen the attack surface.
    Fix: Override unsafe defaults with secure settings (verify=True, auth required, restrictive permissions). Review and harden all tool configurations.
  • medium Rogue Agent · line 414
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

thurbox-cli 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 yesterday.

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 — 1,143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

thurbox-cli, automations, tasks and messages

Working reference indexed by AGENTS.md. The rationale behind these decisions is owned by the docs under docs/; a change that invalidates what this says updates it in the same PR.

thurbox-cli

A second binary (thurbox-cli) drives the same SQLite-backed, tmux-hosted sessions headlessly (no TUI). It shares the database with the TUI; changes appear via PRAGMA data_version polling.
