What it does

Agent Wormhole is an agent skill from BankrBot/skills. Use Agent Wormhole for one-time sealed handoffs between autonomous agents, including encrypted mission briefs, scoped secrets, temporary artifacts, receipts, config drops, CLI/API usage, ECHO holder access, and Bankr x402 paid opens.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `catalog.json`).

It sits in Agent Workflows, covering Autonomous loops. It works with x402. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.

When your agent uses it

  • Tasks that involve Autonomous loops

Example prompts

  • “/agent-wormhole”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit dc47eed. 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:

    • npx
    • node
    • npm
    • curl

    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:

    • builtbyecho.xyz
    • x402.bankr.bot
    • storage.builtbyecho.xyz
    • github.com
    • npmjs.com

    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

Agent Wormhole loads about 1.2k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 416 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 416 words (~1,166 tokens).

“Agent Wormhole opens a temporary encrypted passage for agent handoffs. The payload can be claimed once, then the channel collapses.”
