Alessia Tosi contributed to the alphagov/govuk-chat project by building and enhancing backend features that improved question routing, evaluation workflows, and user safety. She introduced new routing labels and database schema updates to better handle ambiguous or data-dependent queries, and integrated Claude LLM with refined configuration for more reliable automated responses. Using Ruby, YAML, and Ruby on Rails, Alessia developed batch evaluation tools and expanded test coverage with RSpec and Rake tasks, ensuring maintainability and reliability. She also improved error handling in canned responses and established a private infrastructure repository, enabling safer experimentation and aligning the project with policy requirements.
February 2026: Established a private repository for the Gov.uk chat project to enable experimentation and rapid iteration within a controlled environment. This foundational setup in alphagov/govuk-infrastructure enables faster validation of chat features while maintaining governance via repository configuration.

January 2026: Implemented safety- and error-handling enhancements to canned responses in alphagov/govuk-chat to improve reliability during system errors and to mitigate malicious or vulnerable-user interactions. Delivered copy updates across two commits, clarifying responsibilities of Chat, providing an apologetic recovery flow, and removing confusing terms. This work reduces risk, improves user trust, and aligns behavior with policy guidance.

October 2025 monthly summary for alphagov/govuk-chat. Focused on improving the question routing evaluation workflow by expanding JSON output, strengthening test coverage, and cleaning up code quality. Outcomes include adding the answer field to evaluation:generate_question_routing_response output, updating tests to validate the new field, and addressing linting/test refactor cleanups to improve maintainability and reliability.

July 2025 performance summary for alphagov/govuk-chat: Delivered two major features that enhance routing, updated the database schema, and improved Claude integration. Implemented new question routing labels (requires_account_data, unclear_intent) with corresponding configuration and migrations, enabling clearer handling of queries that require user data and ambiguous intents. Enhanced Claude routing reliability by increasing max_tokens to 500 and refining error guidance via updated canned responses. These changes reduce misrouting, improve first-contact resolution, and lower escalation to human agents. The work spans backend schema changes, configuration, and AI tooling integration, demonstrating strong collaboration between data models, APIs, and LLM orchestration.
