tuist

Project-specific PR-review rules for the tuist/tuist Elixir codebases (server, cache, processor, xcode_processor, tuist_common, noora). Focuses on the things only this repo knows — authorization invariants, tenancy, write-only ClickHouse, Mimic placement, migration timestamptz, data-export updates, marketing changelog entries, and i18n.

Project-specific PR-review rules for the tuist/tuist Swift codebase (cli). Focuses on the things only this repo knows — preferring value types, the testing framework choice, and migration of XCTest to Swift Testing.

Guides day-to-day work in Tuist-generated Xcode workspaces, including generation, build and test commands, and buildable folders. Use when working in a Tuist-generated project or when users mention `tuist generate`, `xcodebuild test`, or generated workspaces.

Migrates existing Xcode projects to Tuist generated workspaces with build and run validation, external dependency mapping, and migration checklists. Use when adopting Tuist for an existing app or converting a hand-edited Xcode project to generated projects.

Analyzes Xcode selective testing effectiveness for a test run, showing which test targets were skipped or ran, and diagnosing regressions in test selection. Can compare two test runs to identify what changed.

Compares two Gradle build runs to identify duration regressions, cache changes, and task outcome differences. Can be invoked with build IDs, dashboard URLs, or branch names.

Compares two Xcode build runs to identify duration regressions, cache changes, and new issues. Can be invoked with build IDs, dashboard URLs, or branch names (e.g. `tuist compare-builds --base main --head feature-branch`).

Compares two app bundles to identify size changes, new or removed artifacts, and platform differences. Can be invoked with bundle IDs, dashboard URLs, or branch names.

Design or review a Takt package manifest. Use when working on capabilities, the package Node version, handlers, schemas, or registry-facing package structure.

Design or review Takt actions. Use when working on project-local configured uses of capabilities, including defaults, secret bindings, labels, and ownership metadata.

Interactive getting-started walkthrough for new Takt users. Guides through inspecting the package, understanding the core nouns, scaffolding a first action or workflow, and validating the result. Triggers on "getting started", "new to takt", "first time", "walkthrough", "onboarding", "quickstart", "how do I start", "what do I do first", "learn takt", or whenever the user needs the package, capability, action, and workflow model explained before deeper work.

Design or review Takt workflows. Use when working on orchestration, dependencies, and step wiring across actions.

Guides day-to-day work in Tuist-generated Xcode workspaces, including generation, build and test commands, and buildable folders. Use when working in a Tuist-generated project or when users mention `tuist generate`, `xcodebuild test`, or generated workspaces.

Migrates existing Xcode projects to Tuist generated workspaces with build and run validation, external dependency mapping, and migration checklists. Use when adopting Tuist for an existing app or converting a hand-edited Xcode project to generated projects.

Expert guidance on Swift Concurrency concepts. Use when working with async/await, Tasks, actors, MainActor, Sendable, isolation domains, or debugging concurrency compiler errors. Helps write safe concurrent Swift code.

Project-specific PR-review rules for the Condukt Elixir codebase. Focuses on command execution, cwd scoping, session restore precedence, session store safety, Mimic placement, and the repo's no-typespec convention.

Project-specific PR-review rules for the Schlussel Rust workspace. Focuses on formula-driven OAuth behavior, storage and locking semantics, docs sync, and toolchain alignment.
