What it does

Blackbox is an agent skill from Tommy-yw/RunbookHermes. Delegate coding tasks to Blackbox AI CLI agent. Multi-model agent with built-in judge that runs tasks through multiple LLMs and picks the best result. Requires the blackbox CLI and a Blackbox AI API key.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Hermes-native AIOps agent for evidence-driven incident response, approval-gated remediation, and runbook learning. The licence is MIT.

Example prompts

  • “/blackbox”

Requirements

  • Node.js

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Always use pty=true — Blackbox CLI is an interactive terminal app and will hang without a PTY
  2. Use workdir — keep the agent focused on the right directory
  3. Background for long tasks — use background=true and monitor with process tool
  4. Don't interfere — monitor with poll/log, don't kill sessions because they're slow
  5. Report results — after completion, check what changed and summarize for the user
  6. Credits cost money — Blackbox uses a credit-based system; multi-model mode consumes credits faster
  7. Check prerequisites — verify blackbox CLI is installed before attempting delegation

What it can do on your machine

Read from SKILL.md and the folder at commit 7fd2b9a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • npm
    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    Also links to:

    • blackbox.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Blackbox loads about 1.3k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 411 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 is open-source (GPL-3.0, TypeScript, 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 @blackboxai/cli
  • Or install from source:
    git clone https://github.com/blackboxaicode/cli.git
    cd cli && npm install && npm install -g .
  • 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)

Session Commands

During an interactive session, use these commands:

CommandEffect
/compressShrink conversation history to save tokens
/clearWipe history and start fresh
/statsView current token usage
Ctrl+CCancel current operation

PR Reviews

Clone to a temp directory to avoid modifying the working tree:

terminal(command="REVIEW=$(mktemp -d) && git clone https://github.com/user/repo.git $REVIEW && cd $REVIEW && gh pr checkout 42 && blackbox --prompt 'Review this PR against main. Check for bugs, security issues, and code quality.'", pty=true)

Parallel Work

Spawn multiple Blackbox instances for independent tasks:

terminal(command="blackbox --prompt 'Fix the login bug'", workdir="/tmp/issue-1", background=true, pty=true)
terminal(command="blackbox --prompt 'Add unit tests for auth'", workdir="/tmp/issue-2", background=true, pty=true)

# Monitor all
process(action="list")

Multi-Model Mode

Blackbox's unique feature is running the same task through multiple models and judging the results. Configure which models to use via blackbox configure — select multiple providers to enable the Chairman/judge workflow where the CLI evaluates outputs from different models and picks the best one.

--prompt "task"Non-interactive one-shot execution
--resume-checkpoint "tag"Resume from a saved checkpoint
--yoloAuto-approve all actions and model switches
blackbox sessionStart interactive chat session
blackbox configureChange settings, providers, models
blackbox infoDisplay system information

Vision Support

Blackbox automatically detects images in input and can switch to multimodal analysis. VLM modes:

  • "once" — Switch model for current query only
  • "session" — Switch for entire session
  • "persist" — Stay on current model (no switch)

Token Limits

Control token usage via .blackboxcli/settings.json:

json
{
  "sessionTokenLimit": 32000
}

Rules

  1. Always use pty=true — Blackbox CLI is an interactive terminal app and will hang without a PTY
  2. Use workdir — keep the agent focused on the right directory
  3. Background for long tasks — use background=true and monitor with process tool
  4. Don't interfere — monitor with poll/log, don't kill sessions because they're slow
  5. Report results — after completion, check what changed and summarize for the user
  6. Credits cost money — Blackbox uses a credit-based system; multi-model mode consumes credits faster
  7. Check prerequisites — verify blackbox CLI is installed before attempting delegation
