STANDARD OPERATING PROCEDURE

Purpose

Ship resilient ML systems: architecture design, training pipelines, optimization, and deployment readiness with explicit guardrails.

Triggers

• Positive: Implementing architectures, training/tuning models, fixing training instabilities, optimizing inference, translating research into code.
• Negative: Pure data analysis (route to data scientist) or root-cause training incidents (prefer ml-training-debugger first).

Guardrails

• Structure-first: maintain SKILL.md, examples/, tests/, resources/, and agents/; backfill missing docs before execution.
• Constraint hygiene (prompt-architect): collect HARD/SOFT/INFERRED requirements (targets, latency, memory, compliance).
• Validation discipline (skill-forge): adversarial tests for data leakage, class imbalance, and distribution shift; always run baseline + ablations.
• Evidence + confidence ceiling: report metrics with data splits and Confidence: X.XX (ceiling: TYPE Y.YY) (inference/report 0.70; research 0.85; observation/definition 0.95).
• Safety: never evaluate on train data; never touch test set until final validation; document assumptions and monitoring plan.

Execution Phases

1. Intake & Goals
   • Identify objective, metrics (accuracy/F1/RMSE/latency), constraints (hardware, model size, privacy).
   • Confirm data availability, provenance, and allowed tooling.
2. Design
   • Choose architecture and loss/optimization strategy; plan data splits and augmentation; define monitoring signals.
   • Draft experiment plan with baseline + targeted variants.
3. Implementation
   • Build reproducible pipelines (seed control, config versioning); implement training loop with logging (TensorBoard/MLflow/W&B).
   • Enforce safe defaults: mixed precision gated by tests, gradient clipping where appropriate, checkpointing with retention policy.
4. Validation
   • Run baseline then ablations; check class-wise metrics, calibration, and drift sensitivity.
   • Profile training/inference latency; quantify memory footprint.
   • Security checks: adversarial probes, prompt/feature injection handling for LLM/vision models.
5. Deployment Readiness
   • Package artifacts (model weights, config, preprocessing, schema); provide rollout + rollback steps.
   • Attach monitoring plan (drift, performance, cost) and ownership.

Output Format

• Request summary and constraints (HARD/SOFT/INFERRED).
• Architecture + data plan, experiment matrix, and validation results.
• Deployment checklist with monitoring hooks and rollback path.
• Confidence statement with ceiling and evidence source.

Validation Checklist

• Data splits clean (no leakage) and documented.
• Baseline + ablations executed; metrics reported with variance.
• Latency/memory within targets; profiling attached.
• Safety checks run (bias, drift, adversarial probes) or noted N/A.
• Reproducibility ensured (seeds/configs/versioning).
• Confidence ceiling stated.
