Provide additional context for messages based on the codebase and the context of the message to improve the quality of the translations.

Implement internationalization with Lingui in React and JavaScript applications. Use when adding i18n, translating UI, working with Trans/useLingui/Plural, extracting messages, compiling catalogs, or when the user mentions Lingui, internationalization, i18n, translations, locales, message extraction, ICU MessageFormat, or working with .po files.

Diagnose and fix Lingui SWC plugin compatibility errors with Next.js, Rspack, or other SWC runtimes. Use when seeing errors like "failed to invoke plugin", "failed to run Wasm plugin transform", "out of bounds memory access", or "LayoutError" during builds with @lingui/swc-plugin.

Start or restart the .NET Aspire AppHost via the developer CLI. Always use this, never the developer CLI's `run` command, `aspire run`, or `aspire restart`.

Stop the .NET Aspire AppHost and its Docker containers via the developer CLI. Defaults to the current worktree; supports stopping all worktrees or a specific base port.

Build (compile) the solution via the developer CLI - backend (.NET), frontend (React/TypeScript), and the developer CLI itself.

Commit session changes to git. Identify files from session context, ask user pick message, run validation only if needed. Use when user want commit / save / land changes.

Create a product requirement document (PRD) for a new feature. Use when the user wants to create a new feature, plan a feature, or write a PRD.

Create a GitHub pull request.

Query the local Postgres database of the active Aspire worktree via psql.

Run end-to-end Playwright tests via the developer CLI.

Systematically fix all failing E2E tests using a phased diagnostic approach. Classifies tests as passing, flaky, or permanently failing, then fixes them one by one with progressive scope expansion.

Auto-format code via the developer CLI - backend (.NET via JetBrains cleanupcode), frontend (oxfmt + oxlint --fix), and the developer CLI itself.

Lint code via the developer CLI - backend (.NET via JetBrains inspectcode), frontend (oxlint), and the developer CLI itself.

Pull unmerged PlatformPlatform pull requests into a downstream project by cherry-picking each one onto the platformplatform-updates branch. Renames commits to "PlatformPlatform PR N - title" per the existing convention. Drives a ralph-loop that validates each commit (build, test, format, lint, optional e2e) before moving on. Use in downstream projects that have PlatformPlatform configured as the upstream remote.

Apply a downstream brand to a PlatformPlatform fork. Edits one config file, drops in eight supplied logo assets, renames the solution and CLI to the new brand, and rotates UserSecretsId across every csproj. Skips all other source files. Use once per downstream fork after cloning, or to re-flip a brand later.

Rebuild a stale branch by cherry-picking each commit onto a fresh branch off main, using a ralph-loop to validate each commit (build, test, format, lint, optional e2e) before moving on. Use when a branch has gone stale, has merge conflicts with main, or needs to be split out of a long-lived feature branch.

Send an interrupt signal to a working team agent. Use when an agent is actively running and you need to send it a message without having to wait until it has processed all other messages.

Run backend (.NET) xUnit unit and integration tests via the developer CLI.

Trigger only on explicit "ultra review" or "ultra-review".

Upgrade all backend (.NET/NuGet) and frontend (npm) dependencies to the latest versions. Drives the developer CLI's update-packages command, fixes the CLI itself when it produces a wrong outcome, and produces clean per-package commits for any upgrade that needs more than a version bump.
