Product Direction

Featuresmith Roadmap

Phases 0–4 are shipped in v0.4.0 (current). Everything from Phase 5 onward represents our planned long-term vision toward Dataset Contracts and state management.

Shipped

Foundation & Core Review Capabilities (v0.1 → v0.4)

Monorepo core library, SDK (load, review, diff, score, plan), and CLI (featuresmith)
10 built-in automated reviewers (schema, missingness, duplicates, constants, cardinality, stats, leakage, diff, feature quality)
ML Readiness Score with 7 effective health dimensions (0–100 composite scorecard)
Intelligent Leakage Detection with 6 pattern detectors (correlation, timestamp, duplicate target, etc.)
Centralized Recommendation Engine & inspectable Plan primitive (fs.plan() / featuresmith plan)

Planned

Dataset Contracts, Apply Layer & Validation (v0.5)

featuresmith.apply — generating clean scikit-learn / Polars transformation code from accepted Plans (never a custom runtime)
Automatic post-export re-review and fs.diff() validation
featuresmith.contract module — DatasetContract schema, featuresmith.lock, and featuresmith lock --check

Medium-Term

Planned

Continuous Certification, Observability & Stability (v0.6 → v1.0)

Portable 'Featuresmith-verified' badge linked to featuresmith verify <hash>
Quality History storage abstraction & time-series quality tracking
Scheduled local re-reviews & regression alerts (Slack, email, webhook)
CI/CD contract drift gating (featuresmith-action GitHub Action)
v1.0.0 Stable Dataset Contract & public API freeze milestone

Long-Term

Planned

AI Assistance, Ecosystem Exporters & Scale (v1.1 → v2.0+)

AIProvider protocol (Ollama local default, OpenAI/Anthropic BYO-key), narrative summaries, and NL Plan authoring
dbt model-stub and Feast feature-definition code exporters
MLflow and Weights & Biases run-metadata attachments with Contract fingerprints
Pushdown profiling connectors (DuckDB, Snowflake, BigQuery) & optional Spark/Ray profiler backend
Hosted dashboard tier for team collaboration and shared history
