Paragon Improvements

New filtering options, bulk imports, monorepo support, review model selection, and smarter test execution.

New Features

  • Filter Test Runs by Repository & PR: Filter the test runs page by specific repository and PR number. Links are shareable—send a filtered URL to a teammate and they'll see the same view.
  • View Test Results from GitHub: Test result comments on GitHub PRs now include a "View on Dashboard" link that takes you directly to the filtered runs page for that PR.
  • Bulk Test Import: When importing tests from your repo, select multiple files or entire folders and import them all in one click instead of one at a time.
  • Disable Auto-Reviews Per Repository: Turn off automatic PR reviews for specific repos from the manage repos page. You can still trigger reviews manually by commenting @paragon-review.
  • Manual Review with Model Selection: Choose which model runs your review by adding a mode to your comment. Use @paragon-review max for maximum depth, @paragon-review md for balanced analysis, or @paragon-review fast for quick feedback.
  • Monorepo Support: Configure testing for monorepo setups with multiple packages or apps in a single repository.
  • Auth State for E2E Tests: Pre-captured auth (OAuth, SSO, cookies) now properly applies to step-based tests, automatically skipping login steps when auth is already available.

Improvements

  • Localized GitHub Check Runs: GitHub check run messages (like "Review Complete", "No issues found") now display in your team's configured language.
  • Hindi & Greek Language Support: The dashboard and review comments are now available in Hindi and Greek.
  • Better Test Failure Handling: Tests now continue running even if a step fails, capturing all screenshots and reporting all errors at the end instead of stopping at the first failure.

Major ReleaseJan 4, 2026

Paragon v0.1.0

A major milestone release bringing local repository indexing, new model tiers, significantly reduced token usage, and OmniGrep—a powerful new search capability that transforms how Paragon navigates your codebase.

New Features

  • Local Repository Indexing: Paragon now indexes your repositories locally, enabling faster context retrieval, improved code understanding, and offline-capable analysis without sending your entire codebase to external servers.
  • New Model Tiers: Introducing three optimized model configurations—Max for maximum capability and deep reasoning, MD for balanced performance, and Fast for rapid iteration. Each tier leverages upgraded underlying models for superior output quality.
  • OmniGrep: A context-aware search system that goes beyond traditional grep. OmniGrep understands code semantics, follows import chains, and surfaces relevant code across your entire repository—even when you don't know the exact terms to search for. It intelligently ranks results by relevance to your current task.
  • Complete Slash Commands: All CLI commands are now accessible through the slash command interface for streamlined keyboard-driven workflows.

Improvements

  • 30-50% Reduced Token Usage: Optimized context management and smarter prompting strategies dramatically cut token consumption while maintaining output quality.
  • Enhanced Subagent UI/UX: Redesigned subagent interface with clearer status indicators, better progress visualization, and more intuitive controls for managing parallel agent workflows.
  • Harness Performance: Significant optimizations to the core harness layer delivering faster startup times, reduced memory footprint, and smoother execution across all operations.
  • Stability & Security: Comprehensive audit and resolution of performance bottlenecks and security considerations across the entire CLI.

Bug Fixes

  • Command Palette Screen Size: Fixed rendering issues with the command palette on various screen sizes and terminal dimensions.
  • Auto-Update Reliability: Resolved issues preventing automatic updates from completing successfully on certain systems.

End-to-End Testing in Paragon

Paragon now supports end-to-end testing through natural language. Describe what you want to test in plain English, and Paragon generates and runs Playwright tests for you.

Features

  • Natural Language Test Prompts: Describe any flow, component, or interaction you want to test. Paragon interprets your description and generates the appropriate Playwright tests.
  • Local Environment Intelligence: Tests execute entirely on your machine, leveraging your real dev environment, local services, env vars, secrets, and custom configurations for maximum fidelity.
  • Automatic Report Generation: Paragon runs your tests and opens the Playwright HTML report so you can review results immediately.
  • Persistent Test Files: Generated test files remain in your repository, so you can inspect, modify, or extend them as needed.
