Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00051 | $0.09847 |
| Opus 5.5 | $0.00020 | $0.03939 |
| Sonnet 5.5 | $0.00010 | $0.01969 |
| Haiku 4.5 | $0.00005 | $0.00985 |
Grade A, and why
polymarket scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Polymarket API
Polymarket is a decentralized prediction market where users trade on the outcomes of real-world events. It uses a hybrid-decentralized Central Limit Order Book (CLOB) with off-chain matching and on-chain settlement on Polygon.

Key Concepts (Glossary)
| Term | Definition |
|---|---|
| Event | A collection of related markets grouped under a common topic (e.g., "2024 US Presidential Election"). |
| Market | A single tradeable binary outcome within an event. Each market has Yes and No sides, a condition ID, question ID, and pair of token IDs. |
| Token | Represents a position in a specific outcome (Yes or No). Prices range from 0.00 to 1.00. Winning tokens redeem for $1 USDCe. Also called outcome token. |
| Token ID | The unique identifier for a specific outcome token. Required when placing orders or querying prices. |
| Condition ID | On-chain identifier for a market's resolution condition. Used in CTF operations and as the market identifier in the CLOB. |
| Question ID | Identifier linking a market to its resolution oracle (UMA). |
| Slug | Human-readable URL identifier for a market or event (e.g., polymarket.com/event/[slug]). |
| CLOB | Central Limit Order Book — Polymarket's off-chain order matching system. Orders are matched here before on-chain settlement. |
| Tick Size | Minimum price increment for a market. Usually 0.01 (1 cent) or 0.001 (0.1 cent). |
| Fill | When an order is matched and executed. Orders can be partially or fully filled. |
| Negative Risk (NegRisk) | A multi-outcome event where only one outcome can resolve Yes. Requires negRisk: true in order parameters. |
| CTF | Conditional Token Framework — the on-chain smart contracts that manage outcome tokens. |
| Split | Convert USDCe into a complete set of outcome tokens (one Yes + one No). |
| Merge | Convert a complete set of outcome tokens back into USDCe. |
| Redeem | After resolution, exchange winning tokens for $1 USDCe each. |
| USDCe | Bridged USDC on Polygon — the stablecoin used as collateral on Polymarket. |
| Funder Address | The wallet address that holds funds and tokens for trading. |
| Signature Type | Identifies wallet type: 0 = EOA, 1 = Magic Link proxy (POLY_PROXY), 2 = Gnosis Safe proxy. |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

polymarket is a skill published in the GitHub repository Outsharp/shipp-skills (4 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 51 tokens to every session and 9,847 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
