AI provider ranking: benchmark ingestion, scoring, and model comparison.

What It Provides

• Layer: lib.
• Consumers: module.provider-ranking.

Installation

npm install @lssm/lib.provider-ranking

or

bun add @lssm/lib.provider-ranking

Usage

Import the root entrypoint from @lssm/lib.provider-ranking, or choose a documented subpath when you only need one part of the package surface.

Architecture

• src/eval is part of the package's public or composition surface.
• src/in-memory-store.ts is part of the package's public or composition surface.
• src/index.ts is the root public barrel and package entrypoint.
• src/ingesters is part of the package's public or composition surface.
• src/scoring is part of the package's public or composition surface.
• src/store.ts is part of the package's public or composition surface.
• src/types.ts is shared public type definitions.

Recent Updates

• Replace eslint+prettier by biomejs to optimize speed.
• Resolve lint, build, and type errors across nine packages.
• Add first-class transport, auth, versioning, and BYOK support across all integrations.
• Add AI provider ranking system with ranking-driven model selection.

Notes

• Store interface is the adapter boundary — do not leak implementation details.
• Scoring algorithms must stay deterministic (no randomness, no side effects).
• Benchmark dimension enum is shared across ingesters and scoring — keep in sync.

Agent-aware routing

@lssm/lib.provider-ranking/routing adds deterministic Builder model routing without executing providers. Use selectModelForAgent(input) to classify difficulty, apply manual thinking and risk floors, enforce required capabilities, select cheap/optimized/best/critical policy, and return an inspectable routing decision.

This surface is research/discovery and offline candidate-generation guidance. It is not Protocol V1 qualification, Connect authorization, persisted selection, fallback, or production routing truth. Every suggested candidate must still pass hard policy gates, operation-specific evaluation, durable Agent Host admission, and exact Connect verification before execution.

Critical risk (payments, contract-liability, compliance, destructive data loss, legal) cannot be downgraded by budget mode or manual thinking settings.
