Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

decker-polymarket scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Decker + Polymarket (예측시장) 스킬

Goal

Decker를 통해 Polymarket 예측시장에서 시장 조회·YES/NO 주문 실행. 메인 decker 스킬을 확장. ClawHub polymarket-odds 흡수.

덱커에 쌓인 폴리마켓 시그널 (카피 파이프라인)

스케줄러가 judgment_signalsPM:<slug> + polymarket_* 소스로 넣은 배포용 시그널은 라이브 리더보드와 별개로 조회한다.

용도 호출
에이전트·LLM 인사이트 GET {DECKER_API_URL}/api/v1/llm/opportunities?venue=polymarket&limit=20
특정 마켓만 ...&symbol=PM:<slug> (또는 symbol=<slug>)

응답: venue, count, opportunities[] — 항목에 source, symbol, rationale, conviction 등. 데이터 0건이면 스케줄러·DB 마이그레이션 확인.

사용자 자연어: “폴리마켓 시그널 뭐 있어?” → Assistant가 위 API를 도구로 호출하거나, 사용자에게 텔레그램 시그널 / 채팅 추천종목 을 안내 (DB 기반 요약).

  • 시장 slug는 Polymarket에서 확인

Polymarket 키 설정 (에이전트 안내용)

  2. Polymarket 가입: https://polymarket.com → 지갑 연결 → USDC.e 입금(거래용)
  3. 개인키 추출: MetaMask → 계정 세부정보 → Export Private Key
  4. Decker 설정: 로그인 → 설정 → 거래소 API 설정 → Polymarket
    • Secret Key: Polygon 지갑 개인키(0x로 시작) — 필수
  5. 거래소 선택: exchange_preference를 "Polymarket"로 설정 후 저장
  6. 주문: "Polymarket 시장-slug yes 10 매수" (slug는 polymarket.com에서 확인)

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.
