GPTSportswriter

Generate sports betting research reports using live odds, matchup context, and public/news sources. Supports premium mode with API-backed odds/news and free fallback mode with public-source workflows. Use for best bets of the day, matchup breakdowns, sportsbook-style summaries, and structured betting reports. Prefer this skill for research and summaries, not for placing bets or claiming guaranteed outcomes.

Overview

Use this skill to generate structured sports betting research reports. It can operate in:

• premium mode with API-backed odds and news context
• free mode with public-source workflows and extraction helpers

The goal is to surface current matchups, betting angles, and relevant context in a clean format without pretending certainty.

Data Priority

The skill supports three modes:

• auto (default): use paid sources when configured, otherwise fall back
• premium: require paid sources
• free: use only free/public sources

1. Primary source in premium/auto mode: The Odds API

   • Use it first for:
     • today's matchups
     • moneylines
     • spreads
     • totals
     • sportsbook availability
   • Treat this as the source of truth for what games and lines actually exist right now.

2. Secondary source in premium/auto mode: AskNews + web search

   • Use AskNews first for:
     • recent sports articles
     • matchup previews
     • injury/news context
     • broader same-day coverage summaries
   • Use web search as a fallback or supplement for:
     • betting previews
     • source consensus and disagreement
     • extra matchup-specific context
   • Do not let article coverage override current market reality when the odds data says otherwise.

3. Free mode fallback

   • Use public odds/news pages when the user does not want paid services or when no API keys are configured.
   • Prefer public pages from sources like:
     • Covers
     • OddsShark
     • Yahoo Sports
     • AP
     • ESPN
     • CBS Sports
   • Be explicit that free-mode odds can be more stale and less precise.

Workflow

1. Identify the slate.

   • If the user says "today," use today's games only.
   • If the user names a league, focus there.
   • If the request is broad, cover major in-season sports.
   • For Premier League soccer, use the Odds API sport key soccer_epl.

2. Pull current odds and matchups first.

   • Use The Odds API to get the current slate.
   • Prefer commonly used U.S. books when comparing prices.
   • Note where prices differ meaningfully by book.

3. Search for context.

   • First use scripts/fetch_asknews.py for article context.
   • Then, if needed, search the web for combinations like:
     • best bets today [sport]
     • [league] picks today odds
     • [matchup] betting preview
     • [team] injuries betting line
   • Prefer same-day results.
   • Pull multiple sources before summarizing.

4. Cross-check before recommending anything.

   • Look for overlap between current odds and web consensus.
   • Separate consensus picks from one-off hot takes.
   • Note line sensitivity explicitly.
   • If a good angle depends on getting a better number at a specific book, say that.

5. Write the summary.

   • Include the event, market, current line range, and the reasoning in one or two lines.
   • Mention uncertainty, injuries, schedule spots, or stale-preview risk when relevant.
   • Keep it readable and useful, not breathless.

Required Structured Output

Unless the user explicitly asks for a different format, use this exact output shape:

Fallback Rules

• If The Odds API is unavailable, say that plainly and fall back to web-only summaries.
• If you only find one or two credible angles, do not force a third pick.
• If sources are weak or old, say that clearly in Bottom Line.
• If the user asks for only one best bet, still include:
  • Market
  • Lean
  • Current odds
  • Why this play
  • Main caveat
  • Confidence

Standards

• Do not claim guaranteed wins.
• Do not fabricate odds, records, injuries, or sportsbook prices.
• Prefer "sources are leaning" over "this will hit."
• If the market has already moved away from the good number, say so.
• If the web results are thin or conflicting, say so plainly.

The Odds API Notes

• Use the configured THE_ODDS_API_KEY from environment.
• Prefer current pregame markets where available.
• Compare multiple bookmakers before quoting a range.
• Be explicit when a price is widely available versus only available at one book.
• Use scripts/fetch_odds.py to fetch and normalize live odds before writing the summary.
