blackbox

blackbox is a skill for Claude Code, Codex from nobodyohm-web/Thot. It costs 15 tokens per session (1,349 once invoked), scanned A, a copy of blackbox, MIT.

A command-line coding agent that sends a task to several AI models and uses a judge to choose an implementation.

In plain words
What is it for?
Use it for one-off or longer coding jobs, including building features, editing files, running commands, checkpointing work, and using images or MCP tools.
Why use it?
It gives you one way to compare work from models such as Claude, Codex, Gemini, and Blackbox Pro when completing a coding task.

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

blackbox 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.

Origin

This is a copy

100% identical to blackbox — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Blackbox CLI

Delegate coding tasks to Blackbox AI via the Hermes terminal. Blackbox is a multi-model coding agent CLI that dispatches tasks to multiple LLMs (Claude, Codex, Gemini, Blackbox Pro) and uses a judge to select the best implementation.

The CLI (npm @blackbox_ai/blackbox-cli, binary blackbox) is a TypeScript coding agent (forked from Gemini CLI) and supports interactive sessions, non-interactive one-shots, checkpointing, MCP, and vision model switching.

Prerequisites

  • Node.js 20+ installed
  • Blackbox CLI installed: npm install -g @blackbox_ai/blackbox-cli (binary: blackbox)
  • API key from app.blackbox.ai/dashboard
  • Configured: run blackbox configure and enter your API key
  • Use pty=true in terminal calls — Blackbox CLI is an interactive terminal app

One-Shot Tasks

terminal(command="blackbox --prompt 'Add JWT authentication with refresh tokens to the Express API'", workdir="/path/to/project", pty=true)

For quick scratch work:

terminal(command="cd $(mktemp -d) && git init && blackbox --prompt 'Build a REST API for todos with SQLite'", pty=true)

Background Mode (Long Tasks)

For tasks that take minutes, use background mode so you can monitor progress:

# Start in background with PTY
terminal(command="blackbox --prompt 'Refactor the auth module to use OAuth 2.0'", workdir="~/project", background=true, pty=true)
# Returns session_id

# Monitor progress
process(action="poll", session_id="<id>")
process(action="log", session_id="<id>")

# Send input if Blackbox asks a question
process(action="submit", session_id="<id>", data="yes")

# Kill if needed
process(action="kill", session_id="<id>")

Checkpoints & Resume

Blackbox CLI has built-in checkpoint support for pausing and resuming tasks:

# After a task completes, Blackbox shows a checkpoint tag
# Resume with a follow-up task:
terminal(command="blackbox --resume-checkpoint 'task-abc123-2026-03-06' --prompt 'Now add rate limiting to the endpoints'", workdir="~/project", pty=true)

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.
