⚠️ GAMBLING / PREDICTION MARKETS — Polymarket is real-money betting on event outcomes: check your local laws before use (prediction-market betting is restricted or illegal in some jurisdictions). This is NOT financial advice — Skill Harbor lists the tool, never an endorsement of any trade. 💳 Real money required: order placement needs a funded Polygon (chain 137) wallet and POLYMARKET_PRIVATE_KEY. Selected by Skill Harbor — short listing (the repo states no license, so no content is reproduced): @franalgaba's venue adapter exposes Polymarket market discovery and CLOB data through the `grimoire venue polymarket` CLI — `search-markets` (by query, slug, event, tag, category, league, sport, with open/active/tradable filters), the official passthrough groups `markets` (list/get/search/tags) and `data` (positions, trades, leaderboards), plus legacy aliases (`book`, `midpoint`, `spread`, `price`, `price-history`, `open-orders`). The wrapper intentionally BLOCKS the `wallet`, `bridge`, `approve`, `ctf`, `setup`, `upgrade` and `shell` groups — but order placement IS exposed: spell actions support `order` / `cancel_order` / `cancel_orders` / `cancel_all` (custom op, token_id/price/size/side/order_type, GTC-GTD limit routing and FOK-FAK market routing, `mid_price` metric for spell comparisons). Honest caveats: the agent CAN place real orders — never let it trade unsupervised, double-check every order's token, price, size and side; keep your private key in the secure vault, never pasted; license not stated by the source repo — short listing with a link only, nothing copied; not verified. A different Polymarket listing from another repo (`bluman1-polymarket`) also exists on Skill Harbor — this one is the Grimoire venue-adapter version. Skill Harbor never reviews the code, review it yourself before use. Discovered via skills.sh.
Version:
Install
Prerequisites: the official polymarket CLI installed (brew tap Polymarket/polymarket-cli && brew install polymarket), a funded Polygon (chain 137) wallet, and your Polymarket private key stored in the secure vault — NEVER paste it in chat. Real money is at stake: check your local laws on prediction-market betting first. Install "Polymarket market data and CLOB orders via the Grimoire venue CLI" for me. It gives my agent @franalgaba's venue adapter: query Polymarket markets via grimoire venue polymarket (search-markets with filters, markets list/get/search/tags passthrough, data positions/trades/leaderboards), check adapter health with grimoire venue doctor --adapter polymarket, and manage CLOB orders via spell actions (order/cancel_order/cancel_orders/cancel_all with GTC-GTD limit and FOK-FAK market routing). IMPORTANT: the wrapper blocks wallet/bridge/approve/ctf/setup/shell groups but DOES expose order placement — the agent can place real orders, so never let it trade unsupervised and double-check every order. The repo states no license — fetch from the link only, and reproduce nothing beyond the link. Repository: https://github.com/franalgaba/grimoire/blob/main/skills/grimoire-polymarket/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "grimoire-polymarket". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. install the official polymarket CLI; save POLYMARKET_PRIVATE_KEY in the secure vault — never paste it; verify prediction-market betting is legal where you live; run grimoire venue doctor --adapter polymarket first; review every order before confirming — real money). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
