What it does
Duel Agents is an agent skill from 2aronS/Duel-Agents. OpenClaw integration for Duel Agents routing. Requires DUELAPIKEY from duelagents.com dashboard.
Its SKILL.md is about 220 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with OpenAI, npm and TypeScript. The repository describes itself as: CLI, SDK, and IDE plugins for Duel Agents. The licence is MIT.
Example prompts
- “/duel-agents”
Requirements
- Node.js
- A credential in DUEL_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit c9559e4. 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
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
DUEL_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Duel Agents loads about 217 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 68 words of instructions outside code blocks.
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.
