June 2026 monthly summary for opengovsg/isomer: Delivered a growable code conventions catalog to codify repo-specific smells and best practices for Isomer Next monorepo. Implemented tooling/docs scaffolding (isomer-conventions code skill under .claude/skills/), conventions structure (conventions/ with TEMPLATE.md and per-entry docs), and flows for applying conventions during reviews and for adding new entries. Seeded practical conventions for React, audit logging, and readability. No production code changes; groundwork for improved code quality and onboarding.

In November 2024, the FormSG repository delivered focused UI testing enhancements for the public form flow by adding a Chromatic story and UI tests for the thank-you page. The work includes mock responses for submission success and forms without sections, validating rendering and the 'submit another form' link through simulated interactions. This reduces UX regressions and strengthens release readiness for form-facing pages.
