Changelog

Unreleased

[0.3.0] - 2025-08-14

Added

  • Added a development quality harness covering tests, RuboCop, YARD, and RBS tasks.
  • Added 99% minimum line and branch coverage requirements with expanded provider and context coverage tests.
  • Added an actionlint Rake task for GitHub Actions validation.
  • Added Dependabot configuration for Bundler, Docker, and GitHub Actions updates.
  • Added an opt-in Prescient::Pgvector::Store boundary for validated embedding storage and similarity search.
  • Added configurable Ollama embedding dimensions while preserving strict validation when configured.
  • Added a default example-syntax quality gate that validates Ruby examples without contacting providers.

Changed

  • Updated Ollama embeddings to use /api/embed with strict vector-dimension validation.
  • Restricted fallback to transient/provider-service failures and added the public ProviderError exception for provider-side service errors.
  • Reused registered provider instances and removed redundant health checks during fallback discovery.
  • Updated default chat model names and README examples for current Ollama, Anthropic, OpenAI, and Hugging Face model selections.
  • Updated Hugging Face inference to use the current router feature-extraction and OpenAI-compatible chat-completion APIs.
  • Standardized provider reachability in health results and removed embedding padding/truncation across OpenAI and Hugging Face.
  • Updated Anthropic model listing and health checks to use its /v1/models catalog endpoint.
  • Retained OpenAI Chat Completions for the current normalized public response contract; Responses API migration remains a separately scoped compatibility change.
  • Raised YARD API documentation coverage enforcement to 99% or higher and modernized gem development metadata.
  • Compacted GitHub Actions into focused CI, Pages, release, and security workflows.
  • Added credentialed, provider-selected live smoke tests that remain skipped by default.
  • Restored the RBS/Steep development tasks with a committed Steepfile and curated core API signatures.
  • Expanded Steep coverage to the base abstraction and all provider adapters, including their public operations and HTTP boundaries.
  • Added configurable provider-info sensitive-key sanitization and configurable generic context-field exclusions.
  • Audited README and documentation examples against the current codebase.
  • Removed client method_missing delegation so provider-specific behavior is not exposed through the public client.
  • Prevented default provider registration when required credentials are absent from the environment.
  • Sanitized provider HTTP errors so raw response bodies are not exposed in exception messages.
  • Removed fallback health probes before provider operations to avoid duplicate network requests and race conditions.
  • Clarified health semantics: reachable reports transport availability and ready reports configured-model readiness.
  • Added shared provider health-contract coverage for status, reachability, readiness, and provider identity.

Removed

  • Removed the obsolete PDF changelog and superseded workflow definitions.
