Coding & Dev Tools

Implement modern concurrency with Virtual Threads and Structured Concurrency in Java. Use when implementing Java Virtual Threads (Java 21), Structured Concurrency with StructuredTaskScope, CompletableFuture pipelines, or debugging race conditions.

Configure Python tooling, dependency surfaces, static analysis, and verification gates. Use when editing `pyproject.toml`, `requirements.txt`, `pytest.ini`, `ruff`, `pyright`, CI, or Python release checks.

Mitigate a production incident or urgent regression first, then route to root-cause remediation and a postmortem.

Write idiomatic Kotlin 1.9+ with null safety, sealed classes, data classes, extension functions, delegates, collections, inline/reified generics, and expression syntax. Use for Kotlin language constructs, Java-to-Kotlin migration, lazy delegates, data classes, backing properties, or inline/reified generics; keep language constructs in scope even inside response models, and defer coroutine configuration, Android Context/framework, Retrofit/OkHttp client setup, and other library-specific recipes.

Implement modern PHP error and exception handling patterns. Use when implementing exception hierarchies, error handlers, or custom exceptions in PHP.

Build high-performance declarative UI with Jetpack Compose. Use when writing Composable functions, optimizing recomposition, hoisting state, or working with LazyColumn and side effects; defer deep-link and navigation routing to android-navigation.

Angular CLI usage, code generation, build configuration, and bundle optimization. Use for Angular CLI/build tasks; defer standalone webpack configuration and generic test-runner setup.

Simulator.Company form designer specialist. Use when the user wants to create or modify form templates (a.k.a. Account Templates / «Шаблон рахунків»), define custom field structures, set up account definitions, explore system forms, work with Smart Forms (CDU / Scripts), manage form status, or understand how forms define actor structure. Activate when the user says "create a form", "design a template", "add fields to form", "Account Template", "Шаблон рахунків", "define actor schema", or "what system forms are available".

Simulator.Company Smart Form RUNTIME driver — run/execute an existing Smart Form (CDU / Script / mini-app) on the user's behalf, conversationally, instead of the user clicking through its UI. Use when the user wants to GO THROUGH a smart-form flow: create/submit something an app produces (e.g. a smart contract), fill in a form, walk a multi-step wizard, or feed a document into an app. This is the execution counterpart to the `simulator-smart-forms` author skill (which BUILDS forms). Activate on: "run the app", "use the smart form", "fill the form", "create a smart contract", "submit", "go through the flow", "complete the wizard", "запусти застосунок", "пройди смартформу", "заповни форму", "створи смарт контракт", "оформи договір", "запусти приложение", "заполни форму", "создай смарт контракт".

Record, search, and prune per-project learnings in .claude/learnings.jsonl — typed, confidence-scored, searchable across sessions

Clade coverage-driven project review — walks every VERIFY.md checkpoint, fixes failures in-session, converges when all checkpoints pass. NOT the Claude Code built-in /review (which reviews a single pull request diff) — if the user wants a PR review, route to /review-pr (Clade's PR reviewer) or the CC built-in.

Publish or update one repository-adaptive, exact-SHA pull request without duplicating or broadening authority

Scan project structure and generate ARCHITECTURE.md with a Mermaid module relationship diagram. Use when user says "/map".

Project orchestrator mode — ask clarifying questions, decompose goals into tasks, write proposed-tasks.md for workers to execute. Use inside the Orchestrator Web UI.

Generate `.claude/PROJECT_PROFILE.md` — the project-specific facts that should be loaded into every session (deployment topology, host mapping, env file locations, verification commands). Run once per project after clone.

Planowanie projektów dodatków dla platformy Soneta (enova365, Triva) — interaktywny, etapowy proces od wizji biznesowej po specyfikację implementacyjną, zasilającą skille /soneta-business-xml, /soneta-form-xml i /soneta-programming. Używaj, gdy użytkownik chce zaplanować nowy moduł lub dodatek (założenia, specyfikacja funkcjonalna, struktura danych i interfejsu użytkownika).

Keep a PR merge-ready by triaging comments, resolving clear conflicts, and fixing CI in a loop.

Exploratory ("monkey") QA of a live app as GUEST then LOGGED-IN, then diff. Headed playwright-cli, junk inputs, nav abuse. Use when "monkey test the app", "exploratory QA", "wander like a confused user", or "guest vs logged in". Story CRUD → test-qa. Hostile sweep → test-red-team. This-diff PDCA → test-playwright.

Split current work into small reviewable PRs. Use when the user asks to split a chat, set of changes, branch, or PR.

Close the post-launch improvement loop for any shipped app. Use when asked to "improve the app after launch", "fix the top issues", "post-launch polish", "what should I fix next", "production issues", "iterate on feedback", "post-release improvements", "what is broken in prod", "ship a polish pass", or "make it better.

Comprehensive MDX content sanitizer that escapes angle brackets, generics, and other JSX-conflicting patterns to prevent build failures

Makes iOS apps feel premium, polished, and unmistakably native — SF Symbols mastery, SwiftUI spring animations, haptic feedback choreography, blur/vibrancy materials, Dynamic Type, color system design, and the specific spacings and radii Apple uses. This is about TASTE, not syntax. Activate on 'iOS design polish', 'SwiftUI animation', 'SF Symbols', 'haptic feedback', 'premium iOS feel', 'Apple HIG', 'native iOS look', 'Liquid Glass', 'iOS visual design', 'app polish'.

Failure diagnosis, DAG mutation, and escalation engine for the WinDAGs meta-DAG. Receives failure information and quality vectors from the Evaluator. Classifies failures on four dimensions. Follows a five-level escalation ladder. Applies seven mutation types with saga compensation. Enforces BC-EXEC-002, BC-EXEC-003, BC-FAIL-002, BC-FAIL-005. Activate when operating as the Mutator role in the meta-DAG, when diagnosing node failures, when restructuring a DAG at runtime, or when deciding escalation level.

Deterministic pixel art upscaling using EPX/Scale2x, hq2x/hq4x, and xBR algorithms that add valid sub-pixels through pattern recognition. Activate on 'pixel art scaling', 'EPX', 'Scale2x', 'hq2x', 'hq4x', 'xBR', 'retro game upscaling'. NOT for AI/ML upscaling, photo enlargement, or simple nearest-neighbor.

Analyze complex systems through stocks, flows, and feedback loops to find high-leverage interventions. For organizational, environmental, social, and technical systems exhibiting circular causality. NOT for linear problems or simple cause-effect chains.
