What it can do on your machine

Read from SKILL.md and the folder at commit b50970c. 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 1 file in scripts/ (Python), 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:
- gamma-api.polymarket.com
Also links to:
- claude.ai
- polymarket.com
- docs.polymarket.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

Polymarket loads about 1.6k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 298 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~58
When it runs · the whole SKILL.md, loaded when a task matches: ~1.6k

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); the scripts in this folder are not scanned.

No API key or authentication required. This skill uses Polymarket's public Gamma API.

What this skill does:

Makes HTTPS GET requests to gamma-api.polymarket.com (public, unauthenticated)
Reads market data: odds, volumes, event details, price history
Paper trading is local simulation only - stored in ~/.polymarket/ as JSON files
No real money, no wallet, no blockchain transactions

What this skill does NOT do:

Does not connect to any wallet or financial account
Does not execute real trades or transactions
Does not require or handle any credentials or API keys
Does not send any personal data externally
Cannot be invoked autonomously by the agent (disable-model-invocation: true)

Data stored locally: ~/.polymarket/watchlist.json, ~/.polymarket/portfolio.json

Review scripts/polymarket.py before first use to verify behavior.

Note

This is read-only + paper trading. Real trading requires wallet authentication (not implemented).
