Guidelines for writing Python flow tests (end-to-end behavioral tests). Use this when writing new Python tests in tests/pytests/.

Check which Rust lines are not covered by Rust tests. Use this when you developed new Rust code and want to ensure it is tested.

Implements Manus-style file-based planning for complex tasks. Creates task_plan.md, findings.md, and progress.md. Use when starting complex multi-step tasks, research projects, or any task requiring >5 tool calls.

Build and merge repository .gitignore files or global gitignore files using github/gitignore templates with smart target separation. Use when the user asks to "create gitignore", "build .gitignore", "add gitignore templates", "set up gitignore", "update gitignore", "create global gitignore", or requests "/gitignore". Also trigger when observing projects without .gitignore, seeing untracked files like node_modules/, .env, __pycache__/, or *.log in git status, or after git init in a new repo. Boundary: not for .dockerignore or other non-git ignore files.

Validates Conductor project artifacts for completeness, consistency, and correctness. Use after setup, when diagnosing issues, or before implementation to verify project context.

Structured guide for setting up A/B tests with mandatory gates for hypothesis, metrics, and execution readiness.

Applies proven testing patterns — Arrange-Act-Assert (AAA), Given-When-Then, Test Data Builders, Object Mother, parameterized tests, fixtures, spies, and test doubles — to help write maintainable, reliable, and readable test suites. Use when the user asks about writing unit tests, integration tests, or end-to-end tests; structuring test cases or test suites; applying TDD or BDD practices; working with mocks, stubs, spies, or fakes; improving test coverage or reducing flakiness; or needs guidance on test organization, naming conventions, or assertions in frameworks like Jest, Vitest, pytest, or similar.

Configure app flavors (dev, staging, prod) with environment-specific settings via dart-define-from-file. Use when setting up build variants, per-flavor Firebase projects, or platform-specific configuration.

Orchestrate CI/CD pipelines with GitHub Actions for Flutter apps. Use when setting up quality gates, automated builds, semantic versioning, code signing, or deployment workflows.

Integrate Firebase services including Authentication, Firestore, Cloud Messaging, Crashlytics, and Analytics. Use when adding backend capabilities, push notifications, crash reporting, or remote configuration to a Flutter app.

Structures difficult decisions using Annie Duke's probabilistic thinking and Ben Horowitz's hard decisions frameworks. Use when facing tough choices, applying expected value thinking, or reducing decision paralysis with regret minimization and pre-mortems.

Shifts thinking from tactical to strategic using Anneka Gupta's frameworks for becoming more strategic. Use when escaping feature factory, moving from output to outcomes, or communicating strategic value.

Decides when quality matters vs move fast, based on Dylan Field (Figma) craft philosophy and Brian Chesky (Airbnb) details obsession. Use when balancing shipping speed with excellence, deciding if refactoring is needed, or determining which details create moats vs which to skip.

Build a custom browser-based annotation interface tailored to your data for reviewing LLM traces and collecting structured feedback. Use when you need to build an annotation tool, review traces, or collect human labels.

Set up Playwright 1.49+ with TypeScript for E2E testing using page object model, fixtures, test.describe/test blocks, assertions, selectors, network mocking, CI configuration, and trace viewer.

Scaffold a Next.js 15 App Router project with TypeScript, server/client component conventions, route groups, layouts, loading/error boundaries, Route Handlers, middleware, and SSR/SSG/ISR strategies.

Scaffold a production-ready Actix-web 4.x API with Rust 2024 edition, async handlers, extractors, middleware, SQLx for database access, and structured error handling.

Expert guidance on the Google Agent Development Kit (ADK) for Python. Use this skill when the user asks about building agents, using tools, streaming, callbacks, tutorials, deployment, or advanced architecture with the Google ADK in Python.

Resolves the best-matching Atlassian API endpoints for a given inferred `operation` (what the user wants to do). Use this skill whenever the agent needs to identify which Atlassian REST API endpoint(s) can fulfill a user's intent, especially for Jira issues, projects, boards, sprints, workflows, Confluence pages, spaces, or any cross-product Atlassian operations. Always trigger when the input includes an `operation` field describing an Atlassian action.
