Jun 1, 2025June 2025 performance summary for Shubhamsaboo/parlant: Delivered a major overhaul of the event system with lifespan-aware emission, including a dedicated EventBuffer for transient events, and a clear separation of EngineEvent and EmittedEvent. API refinements and event import cleanups ensure tool-related events are emitted and persisted according to lifespan, improving reliability and observability. Enhanced the MCP CLI and tooling with MCP protocol support, better error messages, optional type handling, robust list parsing, and updated connection settings, complemented by tests and documentation. Implemented targeted bug fixes focusing on typing, parsing robustness, and test stability. Performed dependency updates to maintain compatibility and stability, including fastmcp pinning to avoid breaking changes. Overall, these efforts reduce runtime errors, improve developer experience, and strengthen business value through more reliable tooling and event-driven behavior.

May 1, 2025May 2025 highlights for Shubhamsaboo/parlant focused on reliability, tooling evolution, and expanded parameter support. The release tightened test stability, expanded tool integration capabilities, and advanced the MCP tooling and devcontainer infrastructure, delivering concrete business value through more robust CI, safer deployments, and richer developer tooling. Key features delivered: - Server port randomization for tests: added port randomization to the test harness and propagated the randomized port to the client; updated tests that relied on fixed ports to use the new approach, reducing flaky test failures and enabling parallel test execution. - BDD tests for new tool parameter types (lists, date/time): introduced end-to-end scenarios for newly supported parameter types and ensured correct typing and error handling for optionals. - Choices field support in tool caller and message generator: added required choices field, with prompts updated to reflect this, and corresponding tests. - Prompt and test enhancements for choices: refined message generator prompts to mention choices, and updated tests to verify this behavior. - Batch tooling and infrastructure improvements: updated single_tool_batch.py to reflect latest tool usage, and strengthened test infrastructure with reliability improvements in port handling. - MCP tooling and integration: added MCPToolServer & MCPToolClient, expanded MCP tool support (enums, bools, timedelta, uuid, path), and introduced asynchronous MCP serve with example module and related API fixes; updated tests to run with random ports. - Devcontainer and validation improvements: enhanced initialization to support any folder name starting with 'parlant' and strengthened tool parameter validation for robustness. Major bugs fixed: - OpenAPI server shutdown: fixes to prevent I/O errors on shutdown. - Merge error fix and related minor code cleanups identified during rebase. - Test and URL-related stabilizations: fixed various test URL issues and improved test addresses. - Gemini service adjustments for MCP installations: stabilizing behavior with new MCP configs. Overall impact and accomplishments: - Significantly improved test reliability and CI stability, enabling faster feedback and safer releases. - Expanded tool parameter capabilities and a consistent choices-driven UX, reducing integration friction for developers. - Established a stronger MCP tooling base with asynchronous serving and random-port testing, increasing platform scalability and reliability. - Improved developer experience through devcontainer enhancements and more robust test infrastructure. Technologies/skills demonstrated: - Python tooling and test harness uplift, behavior-driven development (BDD), test automation, and asynchronous API design. - API integration and port management, robust parameter validation, and devcontainer/xDev environment improvements. - Collaborative product mindset: translating business risk reduction (fewer flaky tests, safer deployments) into concrete code changes and tests.

Mar 1, 2025March 2025 monthly summary for Shubhamsaboo/parlant: Implemented precedence-based missing parameter handling to improve tool invocation UX and reliability. Introduced display_name and precedence in ToolParameterOptions, with integration into MissingToolData to enable grouping and prioritization of user prompts when multiple parameters are missing. Refactored missing-parameter filtering to support any integer precedence (including negatives) and updated default precedence to a large value to minimize unnecessary prompts. Expanded test coverage, including BDD tests and plugin-tool scenarios, to ensure robust behavior across core and plugin tooling. These changes reduce failed tool calls, improve parameter completion workflows, and enable scalable multi-tool orchestration across the repository.
