Playbook ML

Describe a decision. Get a deployed specialist. No labeled data.

One command turns a plain-English description into a fine-tuned local model — freight quoting, fraud detection, grain marketing, anything with a scorable outcome. Playbook ML writes the simulator, runs competing strategies, distills what it learned into training data, and fine-tunes a Qwen3-4B specialist you drop into your app.

Install

pip install playbook-ml

Run

  Planning GrainExpert...

  Metric:     expected_profit
  Parameters: basis_threshold, carry_weight, hedge_ratio, storage_capacity... (24 total)
  Scenarios:  SA crop status, seasonal timing, cash flow pressure, basis level...
  Tension:    wide carry favors holding, but cash flow and basis risk favor selling

Done. Specialist lives at ~/.playbook-ml/GrainExpert/specialist/

Playbook ML disappears after this. GrainExpert is yours.

How it works

describe → simulate → compete → extract → fine-tune → deploy

Bootstrap. Opus acts as a domain expert first — identifying the 20-35 variables that actually drive decisions in your domain, then writing a generative simulator that captures all of them. Not a toy with 5 parameters. A real world model from day one.

Tournament. Strategies compete across hundreds of thousands of random scenarios. What consistently wins becomes your training signal. The simulation is the teacher. You never label a single example.

Extract. Conditional principles are distilled from each batch — "when carry is wide and South America is at risk, hold rather than sell" — and a director steers the next batch toward unexplored territory. Breakthrough discoveries (findings that reshape how other principles should be interpreted) are flagged and weighted more heavily in training.

Fine-tune. Tournament results are verbalized into natural language training examples and used to fine-tune Qwen3-4B locally via LoRA. The specialist learns to reason about your domain, not just look up a score.

Deploy. The specialist ships as a standalone folder at ~/.playbook-ml/GrainExpert/specialist/. No Playbook ML, no API calls, no framework. The engine stays in ~/.playbook-ml/GrainExpert/ if you want to keep training.

The specialist

Training produces a standalone module — no Playbook ML dependency, no API calls.

Query it from the terminal:

playbook-ml ask --domain GrainExpert "basis is -0.35, SA drought risk, October"
# → Hold. SA drought risk in October overrides the slightly negative basis...

Or drop it into your app:

from specialist.ask import ask, record

result = ask({"basis": -0.35, "carry": 0.02, "south_america": "drought_risk"})
# → "Hold. SA drought risk overrides the slightly negative basis.
#    Holding 4-6 weeks improves basis by $0.06-0.11 in ~75% of cases..."

record(features, actual_outcome)   # log real outcomes for retraining

Build whatever you want on top — API, iOS app, Slack bot, agent tool. The specialist has no idea Playbook ML exists.

Retrains automatically on real outcomes:

0 2 * * * cd /your/app && python specialist/retrain.py

Playbook ML is scaffolding. You remove it when the building stands.
