College Basketball Data (CBB)

# College Basketball Data (CBB)

Before writing queries, consult `references/api-reference.md` for endpoints, conference IDs, team IDs, and data shapes.

## Setup

Before first use, check if the CLI is available:
```bash
which sports-skills || pip install sports-skills
```
If `pip install` fails with a Python version error, the package requires Python 3.10+. Find a compatible Python:
```bash
python3 --version  # check version
# If < 3.10, try: python3.12 -m pip install sports-skills
# On macOS with Homebrew: /opt/homebrew/bin/python3.12 -m pip install sports-skills
```
No API keys required.

## Quick Start

Prefer the CLI — it avoids Python import path issues:
```bash
sports-skills cbb get_scoreboard
sports-skills cbb get_rankings
sports-skills cbb get_standings --group=23
```

## CRITICAL: Before Any Query

CRITICAL: Before calling any data endpoint, verify:
- Season year is derived from the system prompt's `currentDate` — never hardcoded.
- For standings, the `group` parameter is set to the correct conference ID (see `references/api-reference.md`).
- If only a team name is provided, use `get_teams` to resolve the team ID.

## Choosing the Season

Derive the current year from the system prompt's date (e.g., `currentDate: 2026-02-28` → current year is 2026).

- **If the user specifies a season**, use it as-is.
- **If the user says "current", "this season", or doesn't specify**: The CBB season runs November–April. If the current month is November or December, use `season = current_year + 1`. If January–April, use `season = current_year`. If May–October (offseason), use `season = current_year` (most recently completed season).

## Important: College vs. Pro Differences

- **Standings are per-conference** — use the `group` parameter to filter
- **Rankings replace leaders** — college uses AP Top 25 and Coaches Poll
- **Ranked teams** have a `rank` field (null = unranked) on scoreboard competitors
- **360+ D1 teams** — many games per day during the season (50+ during conference play)
- **March Madness** — NCAA Tournament runs in March/April with 68 teams

## Commands that DO NOT exist — never call these

- ~~`get_odds`~~ / ~~`get_betting_odds`~~ — not available. For prediction market odds, use the polymarket or kalshi skill.
- ~~`search_teams`~~ — does not exist. Use `get_teams` instead.
- ~~`get_box_score`~~ — does not exist. Use `get_game_summary` instead.
- ~~`get_player_ratings`~~ — does not exist. Use `get_player_stats` instead.
- ~~`get_ap_poll`~~ — does not exist. Use `get_rankings` instead.

If a command is not listed in the Commands table above, it does not exist.

## Error Handling

When a command fails, **do not surface raw errors to the user**. Instead:
1. If no events found, check if it's the off-season (CBB runs November–April)
2. If standings are empty without a group filter, try a specific conference
3. During March Madness, the scoreboard will have tournament games
4. Only report failure with a clean message after exhausting alternatives

## Troubleshooting

Error: `sports-skills` command not found
Cause: Package not installed
Solution: Run `pip install sports-skills`

Error: No games found on scoreboard
Cause: CBB is seasonal (November–April); off-season scoreboard will be empty
Solution: Use `get_rankings` or `get_news` year-round; check `get_schedule` for when the season resumes

Error: Too many games returned — hard to filter
Cause: During the season, 50+ games per day are scheduled
Solution: Use `--group` to filter by conference, or `--limit` to cap results

Error: Rankings empty
Cause: Rankings are published weekly during the season (November–March) only
Solution: Use `get_news` in the offseason; rankings resume in November
