NFL data via ESPN public endpoints plus an nflverse backend for schedules, weekly rosters, play-by-play, and normalized player/team stat tables. Zero config, no API keys. Use when: user asks about NFL scores, standings, team rosters, schedules, game stats, box scores, play-by-play, injuries, transactions, betting futures, depth charts, team/player statistics, or NFL news. Don't use when: user asks about football/soccer (use football-data), college football (use cfb-data), or other sports.
Source documentation, not instructions for this website. Review permissions before running any commands.
Before writing queries, consult references/api-reference.md for endpoints, ID conventions, and data shapes.
Before first use, check if the CLI is available:
which sports-skills || pip install sports-skills
If pip install fails (package not found or Python version error), install from GitHub:
pip install git+https://github.com/machina-sports/sports-skills.git
The package requires Python 3.10+. If your default Python is older, use a specific version:
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.
For nflverse-backed commands (get_nflverse_*), install the NFL extra:
pip install sports-skills[nfl]
On Python 3.10+ this installs nflreadpy (the preferred backend) plus pyarrow, which is needed for most nflverse data beyond schedules. On Python 3.9 it installs nfl-data-py instead, since nflreadpy requires 3.10+.
The nfl-data-py backend is a reduced fallback: it cannot serve get_nflverse_team_stats, which returns an explanatory error there. Use Python 3.10+ for full nflverse coverage.
Prefer the CLI — it avoids Python import path issues:
sports-skills nfl get_scoreboard
sports-skills nfl get_standings --season=2025
sports-skills nfl get_teams
Python SDK (alternative):
from sports_skills import nfl
scores = nfl.get_scoreboard({})
standings = nfl.get_standings({"params": {"season": "2025"}})
CRITICAL: Before calling any data endpoint, verify:
currentDate — never hardcoded.get_teams to resolve the team ID before using team-specific commands.Derive the current year from the system prompt's date (e.g., currentDate: 2026-02-16 → current year is 2026).
season = current_year (upcoming season). If September–February, the active season started in the previous calendar year if you're in Jan/Feb, otherwise current year.| Command | Description |

get_nflverse_weekly_rosters | nflverse-backed weekly rosters |
get_nflverse_player_stats | nflverse-backed player stats — season totals by default |
get_nflverse_team_stats | nflverse-backed team stats — season totals by default |
get_nflverse_play_by_play | nflverse-backed play-by-play rows |
See references/api-reference.md for full parameter lists and return shapes.
The two backends use different identifier systems. get_nflverse_schedule is the
bridge: each event carries espn_event_id, which is exactly the ESPN event ID.
To combine nflverse analytics (EPA, win probability, betting lines) with ESPN detail (box scores, drives) for the same game:
get_nflverse_schedule(season=..., week=...).espn_event_id off the event you want.event_id to get_game_summary, get_play_by_play, or
get_win_probability.Two things that do not line up automatically:
LAR and WSH; nflverse uses LA and WAS.
The get_nflverse_* functions accept either and translate. Going the other way
(nflverse → ESPN), resolve via get_teams.00-0033873) are
unrelated, and no crosswalk is available. Match on name plus team instead.Field to watch on schedule rows: total is the combined points actually scored,
while total_line is the betting over/under. Use total_line for market work.

# NFL Data
Before writing queries, consult `references/api-reference.md` for endpoints, ID conventions, 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 (package not found or Python version error), install from GitHub:
```bash
pip install git+https://github.com/machina-sports/sports-skills.git
```
The package requires Python 3.10+. If your default Python is older, use a specific version:
```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.
For nflverse-backed commands (`get_nflverse_*`), install the NFL extra:
```bash
pip install sports-skills[nfl]
```
On Python 3.10+ this installs `nflreadpy` (the preferred backend) plus `pyarrow`, which is needed for most nflverse data beyond schedules. On Python 3.9 it installs `nfl-data-py` instead, since `nflreadpy` requires 3.10+.
The `nfl-data-py` backend is a reduced fallback: it cannot serve `get_nflverse_team_stats`, which returns an explanatory error there. Use Python 3.10+ for full nflverse coverage.
## Quick Start
Prefer the CLI — it avoids Python import path issues:
```bash
sports-skills nfl get_scoreboard
sports-skills nfl get_standings --season=2025
sports-skills nfl get_teams
```
Python SDK (alternative):
```python
from sports_skills import nfl
scores = nfl.get_scoreboard({})
standings = nfl.get_standings({"params": {"season": "2025"}})
```
## CRITICAL: Before Any Query
CRITICAL: Before calling any data endpoint, verify:
- Season year is derived from the system prompt's `currentDate` — never hardcoded.
- If only a team name is provided, call `get_teams` to resolve the team ID before using team-specific commands.
## Choosing the Season
Derive the current year from the system prompt's date (e.g., `currentDate: 2026-02-16` → 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 NFL season runs September–February. If the current month is March–August, use `season = current_year` (upcoming season). If September–February, the active season started in the previous calendar year if you're in Jan/Feb, otherwise current year.

## Using ESPN and nflverse Together
The two backends use different identifier systems. `get_nflverse_schedule` is the
bridge: each event carries `espn_event_id`, which is exactly the ESPN event ID.
To combine nflverse analytics (EPA, win probability, betting lines) with ESPN
detail (box scores, drives) for the same game:
1. Call `get_nflverse_schedule(season=..., week=...)`.
2. Read `espn_event_id` off the event you want.
3. Pass it as `event_id` to `get_game_summary`, `get_play_by_play`, or
`get_win_probability`.
Two things that do not line up automatically:
- **Team abbreviations.** ESPN uses `LAR` and `WSH`; nflverse uses `LA` and `WAS`.
The `get_nflverse_*` functions accept either and translate. Going the other way
(nflverse → ESPN), resolve via `get_teams`.
- **Player IDs.** ESPN athlete IDs and nflverse GSIS IDs (`00-0033873`) are
unrelated, and no crosswalk is available. Match on name plus team instead.
Field to watch on schedule rows: `total` is the combined points actually scored,
while `total_line` is the betting over/under. Use `total_line` for market work.
## Examples
Example 1: Today's scores
User says: "What are today's NFL scores?"
Actions:
1. Call `get_scoreboard()`
Result: All live and recent NFL games with scores and status
Example 2: Conference standings
User says: "Show me the AFC standings"
Actions:
1. Derive season year from `currentDate`
2. Call `get_standings(season=<derived_year>)`
3. Filter results for AFC conference
Result: AFC standings table with W-L-T, PCT, PF, PA per team
Example 3: Team roster
User says: "Who's on the Chiefs roster?"
Actions:
1. Call `get_team_roster(team_id="12")`
Result: Full Chiefs roster with name, position, jersey number, height, weight
Example 4: Super Bowl box score
User says: "How did the Super Bowl go?"
Actions:
1. Call `get_schedule(week=23)` to find the Super Bowl event_id
2. Call `get_game_summary(event_id=<id>)` for full box score
Result: Complete box score with passing/rushing/receiving stats and scoring plays
Example 5: Injury report
User says: "Who's injured on the Chiefs?"
Actions:
1. Call `get_injuries()`
2. Filter results for Kansas City Chiefs (team_id=12)
Result: Chiefs injury list with player name, position, status, and injury type
Example 6: Player statistics
User says: "Show me Patrick Mahomes' stats this season"
Actions:
1. Derive season year from `currentDate`
2. Call `get_player_stats(player_id="3139477", season_year=<derived_year>)`
Result: Season stats by category with value, rank, and per-game averages
Example 7: nflverse weekly rosters
User says: "Give me the Week 1 Chiefs roster from the data table backend"
Actions:
1. Derive season year from `currentDate`
2. Call `get_nflverse_weekly_rosters(season=<derived_year>, week=1, team="KC")`
Result: Weekly roster rows normalized for team, player, position, jersey, and status
Example 8: nflverse play-by-play
User says: "Pull Bills Week 3 play-by-play"
Actions:
1. Derive season year from `currentDate`
2. Call `get_nflverse_play_by_play(season=<derived_year>, week=3, team="BUF")`
Result: Play rows with game_id, down/distance, description, EPA, WP/WPA, and score state
## 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.
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. Catch silently and try alternatives
2. If team name given instead of ID, use `get_teams` to find the ID first
3. 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`. If not on PyPI, install from GitHub: `pip install git+https://github.com/machina-sports/sports-skills.git`
Error: nflverse backend unavailable
Cause: Optional NFL backend extra not installed
Solution: Install `sports-skills[nfl]` so the nflverse provider (`nflreadpy` or compatibility fallback) is available
Error: Team not found by ID
Cause: Wrong or outdated ESPN team ID used
Solution: Call `get_teams` to get the current list of all 32 NFL teams with their IDs
Error: No data returned for a future game
Cause: ESPN only returns data for completed or in-progress games
Solution: Use `get_schedule` to see upcoming game details; `get_scoreboard` only covers active/recent games
Error: Postseason week number returns no results
Cause: Postseason uses unified week numbers (19-23) that differ from regular season
Solution: Use week 19 for Wild Card, 20 for Divisional, 21 for Conference Championship, 23 for Super Bowl
