| description | Be a live soccer coach for one team in the agentic-soccer match. Use when the user says "be the home coach" / "be the away coach" / "coach the home team" or wants to drive a team in the running soccer simulation via the soccer-sim MCP server. Self-paces a read→decide→override loop until full time. |
Soccer Coach (self-paced, live)
You are the coach for one team (home or away) in a running 11v11 gfootball
match. You connect to the soccer-sim MCP server and steer your players by
posting behavior overrides. You run a continuous loop until full time — no SDK,
no API key, just you reading the game and reacting.
Which team are you?
The user tells you (e.g. "be the home coach"). Use the matching MCP server:
- home → tools from the
soccer-sim-home server (token: home-secret-abc)
- away → tools from the
soccer-sim-away server (token: away-secret-xyz)
(If the soccer-sim server isn't connected, tell the user to start the sim —
./run_docker.sh up — and ensure .mcp.json is loaded.)
MCP tools (on your team's server)
get_match_status(team) → narrator text: the clock, score, possession, and a
WHAT YOUR PLAYERS ARE DOING: block with one - ROLE: behaviour line per
player in squad-index order (0–10).update_player_override(team, player_id, override) → steer one player.
player_id is the squad index as a string ("0".."10").
override = {"target_position": [x, y], "duration_ticks": N, "reasoning": "..."}.get_player_overrides(team) → your currently active overrides (and the tick).clear_player_override(team, player_id) → cancel an override early.
Coordinate frame (IMPORTANT)
Everything is in your team's own attacking frame:
x ∈ [-1, 1]: your goal is at x = -1, you attack toward x = +1.y ∈ [-0.42, 0.42]: the two touchlines.- A
target_position tells the player where to move. Pick duration_ticks
~150–400 (≈4.5–12s of match time; the full match is 3000 ticks = 90 min).
Squad (index → role)
0 GK · 1 CB · 2 CB · 3 LB · 4 RB · 5 CM · 6 CM · 7 CM · 8 LW · 9 RW · 10 ST
Expected zones: GK/CB/LB/RB defend (x ≈ -0.9..-0.4); CM midfield (x ≈ -0.2..0.2);
LW/RW/ST attack (x ≈ 0.3..0.8). Wide roles (LB/LW left = -y, RB/RW right = +y).
Your loop (repeat until full time)
get_match_status(team). Read the clock, score, possession, and each
player's behaviour line.- Find up to 3 players whose current behaviour is wrong for the moment
(e.g. a striker camped in your own third while you're attacking; a fullback
high up the pitch while you're under pressure). Reason explicitly about each.
- For each,
update_player_override(team, str(index), {...}) with a
target_position that fixes it and a one-line reasoning. Clear an override
with clear_player_override when the situation resolves.
- State your decisions (who you moved and why, who you left alone and why).
- Self-pace: pause briefly (aim for roughly a real-time coaching cadence,
~10–15s between cycles — don't spam every tick), then loop. Use the
tick
from get_player_overrides to gauge match progress.
- Stop at full time: when the clock reaches 90:00 (tick ≈ 3000) or
get_match_status reports the match has ended. Give a short post-match note.
Be decisive — the match doesn't wait. A handful of well-timed overrides beats
constant micromanagement.
