Create, validate, install, fold, or troubleshoot Codex subagent role TOML, agents-table config, discoverability wiring, and duplicate-role merges. Use when a user asks for a Codex agent role, reviewer agent, role config, TOML role file, subagent setup, or overlapping agents to merge.

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.

Generates test files, creates mocking strategies, analyzes code coverage, designs test architectures, and produces test plans and defect reports across functional, performance, and security testing disciplines. Use when writing unit tests, integration tests, or E2E tests; creating test strategies or automation frameworks; analyzing coverage gaps; performance testing with k6 or Artillery; security testing with OWASP methods; debugging flaky tests; or working on QA, regression, test automation, quality gates, shift-left testing, or test maintenance.

Scan a project to identify Kafka applications, extract schemas from data models, tag PII fields, generate Terraform for Confluent Schema Registry registration, and produce a migration report with rollout ordering. Use this skill when a user asks to analyze a folder or repo for Kafka usage, extract schemas, audit producer/consumer configurations, or generate Terraform for Schema Registry.

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.

Integrate Weavr Secure UI components into React Native and Expo apps. Covers installation, platform-specific setup, secure input and display components, biometric auth, and push provisioning for Apple and Google Wallet. Use when building cross-platform Weavr integrations.

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.

Persistent research knowledge base that accumulates papers, ideas, experiments, claims, and their relationships across the entire research lifecycle. Inspired by Karpathy's LLM Wiki pattern. Use when user says "知识库", "research wiki", "add paper", "wiki query", "查知识库", or wants to build/query a persistent field map.

Enforces systematic root-cause investigation before any fix attempt, using a four-phase process (investigate, analyze patterns, hypothesize, implement). Use when encountering bugs, test failures, build errors, unexpected behavior, performance problems, or integration issues — especially when under pressure, when a "quick fix" seems obvious, or when previous fix attempts have failed. DO NOT TRIGGER for new feature development or refactoring without a known defect.

Craft-first interface design for dashboards, admin panels, SaaS apps, tools, settings pages, data interfaces, and interactive products. Use when designing, building, reviewing, auditing, or refining product UI where visual craft, layout hierarchy, tokens, states, visual direction, or design-system consistency matter. Not for marketing pages, landing pages, campaigns, or brand-only work.

Provides resources to stay updated with Golang news, communities and people to follow. Use when seeking Go learning resources, discovering new libraries, finding community channels, or keeping up with Go language changes and releases.

Modernize Golang code to use recent language features, standard library improvements, and idiomatic patterns. Trigger proactively when writing or reviewing Go code and old-style patterns are detected, or when encountering a deprecation warning. Also use when the user explicitly asks for modernization, a Go version upgrade, or a CI/tooling refresh.
