Skill: stevenho1394/hk-horse-racing (version 1.2.0)

# HK Horse Racing Skill This skill provides two core functions: - **Race card data** - Fetches Hong Kong Jockey Club race cards for a given date, including meeting details, race conditions, and complete horse data (jockey, trainer, barrier, weight, past runs, gear, win/place odds). - **Recommended picks** - Analyzes the field and returns up to 4 recommended horses per race with reasoning (win odds, barrier, weight, recent form, gear), plus an estimated win probability. English output only. Additional features: exclude by horse number or barrier, single-race fetch (`raceNo`), 15‑minute caching, and 60‑second rate limiting between fresh API fetches. Advanced scoring includes trainer/jockey bonuses, barrier effectiveness, and weight penalty. **Repository:** https://github.com/StevenHo1394/openclaw/tree/main/skills/hk-horse-racing ## Tools ### `fetchRaceCard(params)` Fetch race card for a given date (default: today in HKT). Includes race details, per-horse win/place odds, and recommendations for each race. **Parameters (object):** - `date` (string, optional): Date in `YYYY-MM-DD` format. Default: today (HKT). - `classFilter` (array of strings, optional): Filter races by class (e.g., `["Class 4"]`). - `excludeHorseNos` (array of numbers, optional): List of horse numbers to exclude from the `horses` array and from recommendations (e.g., `[7]`). - `excludeBarriers` (array of numbers, optional): List of barrier numbers to exclude from the `horses` array and from recommendations (e.g., `[7]`). - `raceNo` (number, optional): If provided, returns only this specific race. Omit to get all races for the date. - `advancedScoring` (boolean, optional): Enable advanced scoring that includes trainer/jockey bonuses, barrier effectiveness, weight penalty, and light weight bonus. Default: `false`. - `tjBonusWeight` (number, optional): Weight for trainer/jockey combo bonus when `advancedScoring=true`. Range 0-0.3. Default: `0.15`. - `barrierBonusWeight` (number, optional): Weight for barrier effectiveness bonus when `advancedScoring=true`. Range 0-0.2. Default: `0.12`. - `newsBoost` (boolean, optional): When `advancedScoring=true`, also include news sentiment boost (stub, not implemented). Default: `false`. - `lightWeightBonus` (number, optional): Bonus for horses with weight < 120lb when `advancedScoring=true`. Range 0-0.2. Default: `0.05`. **Returns (object):** ```json { "meeting": { "venue": "Happy Valley", "date": "2026-03-18", "weather": null, "trackCondition": "GOOD" }, "races": [ { "raceNo": 2, "distance": 1650, "class": "Class 4", "going": "GOOD", "horses": [ { "horseNo": 1, "horseName": "MIGHTY STEED", "horseId": "HK_2023_J384", "weight": 135, "jockey": "Z Purton", "jockeyAllowance": null, "trainer": "K W Lui", "pastRuns": [7,7,3,3,7,1], "gear": ["CP"], "winOdds": 3.2, "placeOdds": 1.5 } // ... other runners (SB horses excluded) ], "recommendations": [ { "horseName": "MIGHTY STEED", "reason": "Win odds 3.2; barrier 7; weight 135; recent form avg 4.7; gear: CP; TJ bonus +10.0%; Barrier +2.0%", "winProbability": 17.2 } // ... up to 4 best horses ] } // ... ], "source": "hkjc-api", "timestamp": "2026-03-17T17:58:31.793Z" } ``` **Notes:** - Stand-by (SB) horses are excluded from the `horses` list. - `recommendations` are derived from win odds and recent form; only horses with both are considered. - Probabilities are normalized implied probabilities from market odds, adjusted by form. - When `advancedScoring=true`, additional bonuses may be applied: top jockey + top trainer combo (+tjBonusWeight), barrier effectiveness (+/- depending on distance class), and weight penalty for horses carrying significantly above average weight. - **Chinese names**: Chinese horse/trainer/jockey names (name_ch fields) may be present in the source data but are not guaranteed to exist. The skill returns English names by default; if an English name is missing, the field shows `(no English name)`. Chinese names are not used in output. ## Prerequisites - Node.js environment (Node 18+ recommended) - Internet access to reach HKJC API (no authentication required) - The skill depends on `hkjc-api` npm package, which will be installed automatically. ## Installation 1. Ensure the skill directory exists: `/home/node/.openclaw/workspace/skills/hk-horse-racing/` 2. Run `npm install` inside that directory to install dependencies. OpenClaw will typically run `npm install` automatically when the skill is loaded if you set `installCommand` in the plugin manifest. 3. Add the skill to the desired agent's allowed skills via `openclaw configure` or agent config. ## Rate Limiting To avoid overloading the HKJC source, the skill enforces a **1-minute cooldown** between fresh API fetches. Cached data (within 15 minutes) is served without delay. If you attempt a fresh fetch sooner than 60 seconds after the previous one, the skill throws an error: `Rate limit: please wait Xs before fetching new data.` ## Notes - The HKJC API is unofficial and may have rate limits or downtime. - Odds are fetched separately per race (WIN and PLA by default). Additional odds types can be added by modifying the skill. - If the API does not return past performance data, that field will be empty. - The skill caches results for 15 minutes to reduce load. - `advancedScoring` features are experimental and use heuristics; tune `tjBonusWeight`, `barrierBonusWeight`, and `lightWeightBonus` as needed. Weight penalty and light weight bonus apply automatically when `advancedScoring=true`. ## Troubleshooting If the skill fails to install or run: - Check Node.js version (`node --version`). - Ensure `npm install` completed without errors (look for `hkjc-api` in `node_modules`). - Verify outbound network connectivity. - Check agent logs for errors. ## Version History ### v1.2.0 - Added weight penalty in advanced scoring: horses carrying >2 lb above average weight incur a small score penalty. - Added class‑drop bonus stub (requires historical class data to activate). - Refined advanced scoring defaults: `tjBonusWeight` 0.15, `barrierBonusWeight` 0.12. - Added `lightWeightBonus` (default 0.05) to reward horses under 120 lb in advanced scoring. - Expanded top jockey and trainer sets. - Clarified Chinese name handling and removed agent‑specific examples. - Added disclaimer about betting risk. ### v1.1.0 - Added advanced scoring: trainer/jockey top‑pair bonus, barrier effectiveness by distance, news sentiment placeholder. - New parameters: `advancedScoring`, `tjBonusWeight`, `barrierBonusWeight`, `newsBoost`. - Changed license from ISC to MIT. - Removed agent‑specific examples (e.g., Jonah). - Clarified Chinese name handling: may exist but not guaranteed; English‑only output. ### v1.0.0 - Initial stable release with race card fetch, top 4 recommendations, strict English output, exclusions, single‑race fetch, rate limiting, and caching. ## Disclaimer This skill is provided for informational purposes only.
