Blackbox

What it does

When your agent uses it

• AI & LLM Engineering work in your project

Example prompts

• “/blackbox”

Requirements

• Node.js

Workflow steps

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

1. 1Always use pty=true — Blackbox CLI is an interactive terminal app and will hang without a PTY
2. 2Use workdir — keep the agent focused on the right directory
3. 3Background for long tasks — use background=true and monitor with process tool
4. 4Don't interfere — monitor with poll/log, don't kill sessions because they're slow
5. 5Report results — after completion, check what changed and summarize for the user
6. 6Credits cost money — Blackbox uses a credit-based system; multi-model mode consumes credits faster
7. 7Check 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 b94464a. 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
  • gh
  • npm

  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 1.4k tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 449 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~17

When it runs · the whole SKILL.md, loaded when a task matches

~1.4k

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

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.
