@contractspec/lib.observability

Website: https://contractspec.io

OpenTelemetry-based observability primitives.

What It Provides

• Layer: lib.
• Consumers: evolution, progressive-delivery, bundles.
• src/pipeline/ contains pipeline stages and orchestration helpers.
• Related ContractSpec packages include @contractspec/lib.contracts-integrations, @contractspec/lib.contracts-spec, @contractspec/lib.lifecycle, @contractspec/tool.bun, @contractspec/tool.typescript.
• src/pipeline/ contains pipeline stages and orchestration helpers.

Installation

npm install @contractspec/lib.observability

or

bun add @contractspec/lib.observability

Usage

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

Architecture

• src/anomaly is part of the package's public or composition surface.
• src/index.ts is the root public barrel and package entrypoint.
• src/intent is part of the package's public or composition surface.
• src/logging is part of the package's public or composition surface.
• src/metrics is part of the package's public or composition surface.
• src/pipeline/ contains pipeline stages and orchestration helpers.
• src/telemetry is part of the package's public or composition surface.

Public Entry Points

• Export . resolves through ./src/index.ts.
• Export ./anomaly/alert-manager resolves through ./src/anomaly/alert-manager.ts.

Recent Updates

• Replace eslint+prettier by biomejs to optimize speed.
• Circular import issue.
• Normalize formatting across contracts-integrations, composio, and observability.
• Add AI provider ranking system with ranking-driven model selection.

Notes

• OTel span and metric naming conventions must stay consistent across the platform.
• Pipeline interfaces are adapter boundaries — do not leak vendor-specific details.
• Anomaly detection thresholds affect alerting; changes require validation.
