What it does
Polymarket is an agent skill from RedWoodOG/Hermes-Desktop. Query Polymarket prediction market data — search markets, get prices, orderbooks, and price history. Read-only via public REST APIs, no API key needed.
Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/api-endpoints.md` and `scripts/polymarket.py`).
It sits in Backend & APIs, covering Stock and market analysis and REST APIs. It works with Polymarket.
When your agent uses it
- Tasks that involve Stock and market analysis
- Tasks that involve REST APIs
Example prompts
- “/polymarket”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Gamma API at gamma-api.polymarket.com — Discovery, search, browsing
- CLOB API at clob.polymarket.com — Real-time prices, orderbooks, history
- Data API at data-api.polymarket.com — Trades, open interest
What it can do on your machine
Read from SKILL.md and the folder at commit be46b39. 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.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 757 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 361 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.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 361 words (~757 tokens).
