Use whenever Java/JVM API tests need writing or fixing: loose assertions that let an empty 200 pass, slow sequential suites, or hand-rolled HTTP clients. Writes REST Assured given/when/then tests: status, JSON and XML path checks, auth, reusable specs, schema checks, Maven or Gradle and CI reports.

Use for any question or task about Selenium WebDriver tests in Java, Python, C# or other bindings, including quick how-to questions and one pasted test to fix: explicit waits instead of sleeps, stable locators instead of absolute XPath, driver version errors (Selenium Manager), page objects, BiDi console errors, Grid in Docker and JUnit XML. New projects usually pick Playwright.

Coordina multipli agenti AI CLI (Kimi, Claude, Gemini, OpenAI, ecc.) che lavorano contemporaneamente sullo stesso progetto e mantiene una memoria collettiva (wiki) di tutte le sessioni passate. Usa questa skill SEMPRE quando lavori in parallelo con altre AI CLI, quando devi salvare lo stato di una sessione condivisa, quando vuoi evitare sovrascritture su file toccati da altri agenti, quando devi chiedere "questo lavoro è già stato fatto? questo bug si è già visto?", o quando l'utente parla di "multi-tap", "registry agenti", "coordination", "lock file", "handoff condiviso", "wiki delle sessioni", "chi sta lavorando su cosa" o "evitare che le AI si pestino i piedi".

Perform identical, surgical edits across many GitHub repositories without cloning them locally — using the `gh` CLI's Contents API to read files, create branches, commit changes, and open PRs in bulk. Use this skill whenever the user wants to make the same small change (update a README, remove a deprecated badge, fix a link, bump a config) across more than a handful of repos they own or maintain. Trigger this skill on phrases like "across all my repos", "in each of these repos", "bulk update", "open PRs for all of them", "without cloning", "deprecated X in many repos", or any task where the work is mechanically identical and spans 5+ repositories. Even when the user describes the task in domain terms (e.g. "the Snyk badge is deprecated everywhere") rather than "multi-repo edit", trigger this skill — it's the right tool whenever cloning N repos to make a one-line change would be wasteful.

Generate, edit, refactor, and review Java source code according to the Google Java Style Guide. Use when Codex is asked to write Java code, update .java files, format Java snippets, review Java style, or keep Java output compliant with Google style conventions for file structure, imports, formatting, naming, comments, programming practices, and Javadoc.

Use when migrating Docusaurus projects from v2 to v3 — upgrade @docusaurus/React/MDX/prism dependencies, rewrite MDX v1 syntax to v3 (escape bare { and <, fix autolinks), swap @tsconfig/docusaurus for @docusaurus/tsconfig, update Prism imports, and resolve React 18 breaking changes. Triggers on tasks involving MDX v1 to v3 migration, Docusaurus dependency updates, React 18 compatibility, or v2/v3 breaking changes.

Creates and manages database migrations, including generating migration files, writing up/down migration logic, running schema changes, resolving migration conflicts, and testing rollbacks. Use when asked to add a column, rename a table, ALTER TABLE, create a migration file, run db migrate, handle schema changes, or work with migration tools like Alembic, Knex, Rails ActiveRecord, Flyway, or Liquibase.

Break a plan, spec, or PRD into independently-grabbable issues on the project issue tracker using tracer-bullet vertical slices. Specialised for the Tessl monorepo stack. Use when user wants to convert a plan into issues, create implementation tickets, or break down work into issues.

Auto-provision a virtual Visa card to complete an online purchase. Use when user asks to buy something and needs payment, or explicitly mentions cypher-pay/agent-pay. Handles onboarding (email OTP + KYC — once ever), token generation (once per device), funding, card creation, 3DS, and card lifecycle.

End-of-session knowledge cleanup with OCD-level rigor — reconciles project docs (CLAUDE.md, README.md, docs/) and agent memory against the code so nothing rots. 会话结束后对项目文档和记忆进行洁癖级审查与同步。MUST trigger when the user says: "sync up", "tidy up docs", "update memory", "clean up docs", "/sync", "/neat", "同步一下", "整理文档", "整理一下", "更新记忆", "梳理一下", "收尾", "这个阶段做完了", "新人能直接上手", or any phrase suggesting a dev milestone where knowledge needs reconciliation. Also trigger when the user reports stale docs, conflicting memories, or wants a clean handoff to teammates or other agents. Bare "整理" / "tidy" with prior dev context counts — do not under-trigger. Cross-platform: works on Claude Code, OpenAI Codex, OpenCode, and OpenClaw.

Captures the current session's repeatable process into a reusable SKILL.md skill file by interviewing the user, extracting steps from the conversation, generating YAML frontmatter, and writing structured markdown instructions. Use when the user wants to create a skill, save a workflow as a skill, turn a process into a reusable skill, or mentions "skillify", "create skill", "make a skill", "save as skill", "capture workflow", "turn this into a skill", "new skill", or wants to automate a repeatable process they just performed.

Record polished UI demo videos using Playwright. Use when the user asks to create a demo, walkthrough, screen recording, or tutorial video of a web application. Produces WebM videos with visible cursor, natural pacing, and professional feel.

Open-source pipeline: fork, sanitize, and package private projects for safe public release. Chains 3 agents (forker, sanitizer, packager). Triggers: '/opensource', 'open source this', 'make this public', 'prepare for open source'.

Draft cold emails, warm intro blurbs, follow-ups, update emails, and investor communications for fundraising. Use when the user wants outreach to angels, VCs, strategic investors, or accelerators and needs concise, personalized, investor-facing messaging.

Analyze an unfamiliar codebase and generate a structured onboarding guide with architecture map, key entry points, conventions, and a starter CLAUDE.md. Use when joining a new project or setting up Claude Code for the first time in a repo.

Rapidly screens batches of 10-50+ startups from pitch events, demo days, or accelerator showcases into investment tiers. Scores startups on traction, team, market size, and differentiation; classifies into 4 priority tiers; validates top candidates via web research; generates tier rankings and shortlist comparison tables. Use for batch deal screening, startup triage, demo day prep, cohort evaluation, or dealflow prioritization.

Configures Supabase Realtime clients with worker:true to prevent background tab disconnections. Implements heartbeat monitoring and reconnection strategies. Use when fixing realtime disconnects, configuring worker-based realtime clients, implementing heartbeat resilience, or handling browser tab WebSocket stability.

Use when writing or reviewing T-SQL, creating stored procedures, designing table schemas, writing views, building migrations, defining custom types, or architecting a SQL Server application database. Also use when writing RAISERROR patterns, CHECK constraints with scalar functions, base/subtype table hierarchies, composite key designs, role-scoped views with row-level security, or idempotent DDL scripts. If you are touching SQL for an application database, use this skill.

Generates micro Flutter/Dart UI components (atoms/molecules) following Atomic Design patterns. Uses StatelessWidget for atoms and HookConsumerWidget for molecules, including form validation classes and auto-generated widget tests with mocktail mocks. Use when the user asks to create small Flutter UI components such as buttons, text fields, inputs, cards, or reusable widgets following Atomic Design principles, or when they need a Flutter atom, molecule, or micro-UI component with Riverpod integration.

Analyze collaboration patterns (HOW) and compute metrics from captured sessions. Use when reviewing collaboration quality, analyzing human-AI interaction, computing session metrics. Triggers include "retrospect collab", "collaboration analysis", "session patterns", "how am I collaborating".
