_LLM_SYSTEM = """\
You are a creative director writing vivid, BRUTAL video-generation prompts for African street fighting scenes.
Each prompt must be ONE sentence, 18-38 words, cinematic, specific and full of action.
Emphasize FAST, continuous, explosive, savage motion — describe action mid-movement, never static, posed, or \
slow-motion. The motion must PROGRESS FORWARD in one direction through the clip: no reversing, no \
rewinding, no looping back to the starting pose, no boomerang or back-and-forth motion.
This is a full MMA / no-rules street fight, NOT boxing — do NOT default to only punches. Across clips \
draw widely from the WHOLE arsenal: head and body punches, but also high kicks, low leg kicks, push \
kicks, spinning back-kicks, flying knees, knees in the clinch, elbow strikes, takedowns and slams, \
sprawls, ground-and-pound, mount and guard scrambles, chokes and submission attempts, throws, \
shoulder charges and dirty street-fighting. Each prompt should center on a DIFFERENT technique than \
the recent ones — favour kicks, knees, elbows, grappling and ground work over plain punches.
BE ACROBATIC and SPECTACULAR: many clips should feature athletic, gravity-defying movement — wall-runs, \
cartwheel and tornado kicks, backflip and roll evasions, kip-ups, springboards off walls/crates/cars, \
no-hands capoeira spins, flying/diving attacks, hurricanrana and aerial takedowns, parkour vaults. The \
fighters are explosive, agile and stylish, not flat-footed.
USE THE SCENERY: make fighters interact with the township environment as part of the action — vaulting \
parked cars, leaping off low rooftops or stacked crates, crashing through market stalls and fruit carts, \
bouncing off corrugated fences and shack walls, kicking up dust, scattering the pressing crowd. The \
setting is a living, destructible playground, not a flat empty floor.
Make it gritty, visceral and BRUTAL: it is encouraged to OFTEN (but not every clip) show the damage — a \
bloodied nose or lip, a split brow, blood spray, sweat-and-blood on the face, a stagger or knockdown — \
when a hard blow lands.
ALWAYS specify CAMERA WORK in the prompt: describe a kinetic camera move and angle — a low tracking shot, \
a fast whip-pan following a spin, a sweeping crane/orbit around an aerial move, a tight handheld close-up \
shaking on impact, an overhead ground shot, an over-the-shoulder angle, a wide scenic establishing move, \
or a dramatic push-in on the cleanest strike. The camera should feel kinetic and dynamic, never locked off.
Make every shot feel SCENIC and cinematic — rich depth, dramatic lighting and atmosphere (dust, smoke, \
sparks, swirling crowd). Vary lighting (dusk, generator light, noon sun, harsh spotlight, headlights, \
fire-barrel glow).
Always refer to each fighter by their NAME (given in the user message), not only by their description.
WARDROBE CONTINUITY (critical): every clip of a match — and every chained part within a clip, plus the \
outcome clips — must show each fighter in the IDENTICAL outfit: the same garments, exact same colours, \
same hair and accessories given in their description. Restate the key clothing details so they stay \
constant; NEVER change, add, remove, or restyle clothing, and never switch a fighter to different \
shorts/gloves/colours between shots.
ENVIRONMENT CONTINUITY (critical): stay in the ONE given location for the whole match — the same \
ring/yard/street, the same surfaces, walls, structures, lighting and crowd. Describe the same place \
every time; never move the fight to a different setting between clips or outcomes.
Do NOT use generic phrases like "high quality" or "realistic". Return ONLY the prompt, no quotes."""

  • the FINISH — the last decisive action that ENDS the fight: the knockout blow landing and the loser \
crashing down, the fight-ending submission, the final overwhelming flurry, or the beaten fighter / their \
corner signalling they cannot continue. Describe FORWARD, explosive, savage motion, with dynamic camera \
work (low angle, whip-pan, handheld push-in) — this is the climax, make it hit hard.
  • the VICTORY — immediately after: the WINNING fighter and the REFEREE raising the winner's arm in \
victory (for a draw, the referee raises BOTH fighters' arms). Show triumph, exhaustion, the roaring crowd, \
and the referee's raised-arm gesture explicitly, with a celebratory camera move (push-in, crane, orbit).
Be specific about body language, expression, lighting, atmosphere and CAMERA movement.
Refer to fighters by their NAME (given in the user message).
WARDROBE + LOCATION CONTINUITY (critical): the outcome happens in the SAME match — keep each fighter in \
the IDENTICAL outfit (same garments, exact colours, hair, accessories) described, and in the SAME \
location as the fight, with consistent background, surfaces and lighting. Never change clothing or move \
to a different place.

WHAT THIS SCRIPT DOES
─────────────────────
  Stage 1 – Characters
    Generates fighter portrait profiles via CoderAI's image model (4 reference
    images each). Fighters span South Africa and Uganda/Kampala.

  Stage 2 – Environments
    Generates township location profiles (3 reference images each).
    Locations span South Africa and Uganda/Kampala.

  Stage 3 – Videos
    a) Fight matches — one short (40-50s) and one long (65-75s) version per
       pair, composed from multiple 4-8s clips. Same clips are reused for both.
    b) Outcome videos — win / ko_win / retire per fighter, plus ONE draw per
       match. Each is a two-shot sequence: the decisive FINISH (KO, retirement,
       last action) then the VICTORY (winner + referee raising the arm), assembled
       into one clip. Length via --outcome-min/max-frames.
    Prompts are generated by an LLM (--text-model) for maximum variety, or
    fall back to a static template pool if no text model is configured.

FIGHTER POOL
────────────
  South Africa: {sa_fighters}
  Uganda/Kampala: {ug_fighters}

ENVIRONMENT POOL

  South Africa: {sa_envs}
  Uganda/Kampala: {ug_envs}

REQUIREMENTS
────────────
  • CoderAI running (default: http://127.0.0.1:8776)
  • Image generation model (for characters + environments)
  • Video generation model (for fight videos)
  • Text/LLM model (optional, for varied prompts — recommended)
  • ffmpeg + ffprobe on PATH (for clip concatenation)

EXAMPLES
────────
  # Full run — auto-selects models, generates everything:
  python tools/gen_township_fighters.py

  # Specify models explicitly:
  python tools/gen_township_fighters.py \\
    --image-model "owner/my-image-model" \\
    --video-model "owner/my-video-model" \\
    --text-model  "owner/my-llm-model"

  # Only generate Uganda/Kampala content:
  python tools/gen_township_fighters.py --region kampala

  # Reuse fighters/environments from the local output directory (re-uploads to
  # CoderAI if needed), then generate new fight videos:
  python tools/gen_township_fighters.py \\
    --reuse-fighters --reuse-environments --video-model "owner/video-model"

  # Pick specific saved profiles by name (loads from local dir, uploads if needed):
  python tools/gen_township_fighters.py \\
    --fighters khumalo,ssebuliba \\
    --environments katwe_backyard,township_ring \\
    --skip-characters --skip-environments

  # Include female fighters (namutebi):
  python tools/gen_township_fighters.py --include-female

  # Generate only videos (characters + environments already done):
  python tools/gen_township_fighters.py \\
    --skip-characters --skip-environments \\
    --video-model "owner/my-video-model"

  # Generate ONLY characters (no environments, no videos):
  python tools/gen_township_fighters.py --only-characters

  # Generate ONLY environments:
  python tools/gen_township_fighters.py --only-environments

  # Generate BOTH characters and environments, but no videos:
  python tools/gen_township_fighters.py --only-assets

  # Stage 3 split — write all video prompts now (saved to videos/prompts.json):
  python tools/gen_township_fighters.py --reuse-fighters --reuse-environments --only-prompts

  # …then render the videos later from those saved prompts (no text model load):
  python tools/gen_township_fighters.py --only-videos

  # Remote CoderAI with API key, custom output, slower FPS:
  python tools/gen_township_fighters.py \\
    --base-url http://192.168.1.10:8776 --api-key sk-abc123 \\
    --out-dir /data/fights --fps 24

  # Increase delay between requests if hitting rate limits:
  python tools/gen_township_fighters.py --clip-delay 15
