Mint Release Notes

v1.4.2 - Web Search & Specialized Personas

Mint 1.4.2 introduces powerful information retrieval capabilities with integrated Web Search, smarter file discovery, and a suite of specialized agent personas with consistent "Mint" personality traits.

Highlights

  • Integrated Web Search: The agent can now search the internet to provide up-to-date information.
  • Specialized Personas: Six distinct agent personas (Default, Coder, Researcher, Creative, Manager, Reviewer) with a consistent "Mint" personality.
  • Smart Path Discovery: New find_path tool for finding files and folders by name or partial path.
  • Enhanced Thai Support: Refined personality and polite particles ("ค่ะ", "นะคะ") when communicating in Thai.
  • Deep Context Integration: Better chat history management for seamless multi-turn conversations.

New Features

  • Web Search Integration

    • Added web_search tool to code_agent.
    • Enables the agent to fetch real-time data from the web when it lacks local knowledge.

  • Persona-Driven Experts

    • Introduced the Agent Orchestrator with six specialized roles:
      • Mint Default: Friendly and versatile assistant.
      • Mint Coder: Technical expert focusing on best practices.
      • Mint Researcher: Analytical role focused on data and facts.
      • Mint Creative: Expressive partner for brainstorming.
      • Mint Manager: Efficiency-focused role for task planning.
      • Mint Reviewer: Senior critic for code and content quality.

  • Improved File Operations

    • New find_path utility to locate files and directories within the workspace.
    • Smarter path resolution for all file system actions.

  • Refined Agent Personality

    • Standardized "Mint" personality across all modules.
    • Added specific Thai language support to ensure polite and consistent responses in Thai.

Improvements & Fixes

  • CLI Stability

    • Improved CLI input handling and streaming performance.
    • Better reporting of tool execution in the terminal UI.

  • Router Improvements

    • Enhanced intent detection in chat_router to better distinguish between general chat and complex coding tasks.
    • Added more Thai keyword support for better localization.

  • Tool Execution

    • Hardened tool execution paths and improved error reporting when tools fail.
    • Better handling of large tool outputs with truncation logic.

Documentation & Maintenance

  • Major overhaul of README.md to reflect new capabilities and architecture.
  • Updated BUILD_AND_RELEASE.md with refined release procedures.
  • Cleaned up dependency list in package.json.

Testing

  • Added tests for findPath and webSearch helpers.
  • Verified persona switching and personality consistency.
  • Current test status:
    • 85 tests passed

v1.4.1 - CLI Agent Hardening & Stability

Mint 1.4.1 focuses on making the CLI and coding agent behave more like a real agent, while tightening several unsafe execution paths and improving reliability across provider selection, workspace handling, and action execution.

Highlights

  • CLI one-shot chat now executes returned actions, not just text responses
  • Code Mode now uses only supported coding providers instead of silently falling through
  • Agent loop is more resilient when a model returns malformed JSON
  • Workspace detection is safer and no longer matches sibling paths by prefix
  • Multiple shell execution paths were hardened to reduce command injection risk

CLI & Agent Improvements

  • One-shot CLI action execution

    • mint chat <message> and equivalent one-shot paths now execute structured actions the same way as interactive chat.
    • This fixes cases where Mint would say it was opening or searching for something but would not actually perform the action.

  • Better Code Mode provider routing

    • Code Mode now selects from providers that are actually supported by the coding workflow:
      • gemini
      • anthropic
      • openai
      • local_openai
    • Unsupported coding providers such as ollama or huggingface no longer appear to be active while silently falling back elsewhere.

  • More robust agent loop

    • Code Mode now attempts JSON repair when a provider returns malformed structured output.
    • Instead of failing immediately on the first invalid JSON response, Mint asks the model to reformat the reply into valid JSON and retries.

  • Accurate step reporting

    • Code Mode now reports the actual number of executed steps instead of always showing the maximum configured step count.

Security & Safety Fixes

  • Hardened URL and file opening paths

    • Replaced shell-string execution with argument-based process execution in browser and file action handlers.

  • Hardened app launching

    • open_app no longer builds launcher commands through shell interpolation for common launch paths.

  • Hardened Docker plugin

    • Docker actions now use argument-based execution instead of shell-string concatenation.

  • Safer workflow process matching

    • Custom workflow process-name matching now escapes regex characters before building a matcher.

Workspace & Config Fixes

  • Workspace path matching fixed

    • Workspace detection no longer treats sibling folders with the same prefix as the same project.
    • Example: /project no longer incorrectly matches /project-two

  • Workspace test isolation

    • Workspace storage can now be redirected for tests through an override path, making tests more reliable in restricted environments.

  • Proactive cooldown config consistency

    • Proactive suggestion cooldown now reads from the same config source as the rest of the app.

  • Provider fallback logic improved

    • Non-Gemini providers are no longer blocked by a missing Gemini API key before routing even begins.

Documentation

  • Rewrote the README to better reflect Mint’s current state as a desktop assistant plus CLI coding agent
  • Clarified current agent capabilities, supported workflows, and provider behavior

Testing

  • Expanded regression coverage for:

    • Docker plugin execution
    • Provider routing helpers
    • Code agent helper behavior
    • Workspace path boundary handling

  • Current test status:

    • 77 tests passed

Notes

Mint 1.4.1 is not a major feature release. It is a stabilization release aimed at making existing agentic workflows safer, more honest about what provider is actually being used, and more reliable in day-to-day CLI usage.
