Sync portfolio positions from Polymarket, Kalshi, and Manifold

  • Business, Finance & HR work in your project
  • SKILL.md covers Polymarket Position Sync, Kalshi Position Sync, Manifold Position Sync and Unified Portfolio Sync, plus 1 more section
  • Runs TypeScript scripts from its folder; calls python3; reaches polygon-rpc.com and gamma-api.polymarket.com; needs KALSHI_PASSWORD and API_KEY

What it does

Portfolio Sync is an agent skill from alsk1992/CloddsBot. Sync portfolio positions from Polymarket, Kalshi, and Manifold

Its SKILL.md is about 3.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `index.ts`).

It sits in Business, Finance & HR. It works with Polymarket and Kalshi. The repository describes itself as: Open Source AI trading agent that operates autonomously across 1000+ markets - Polymarket, Kalshi, Binance, Hyperliquid, Solana DEXs, 5 EVM chains. Scans for edge, executes… The licence is MIT.

When your agent uses it

  • Business, Finance & HR work in your project

Example prompts

  • “/portfolio-sync”

Requirements

  • Python 3
  • Node.js
  • A credential in API_KEY
  • A credential in MANIFOLD_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit c930628. 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

    Ships script files (TypeScript), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    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:

    • polygon-rpc.com
    • gamma-api.polymarket.com
    • trading-api.kalshi.com
    • api.manifold.markets

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • KALSHI_PASSWORD
    • API_KEY
    • MANIFOLD_API_KEY

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

Context cost

Portfolio Sync loads about 3.6k tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 56 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~3.6k

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.
