persimmon-automation-labs Skill

Interactive guided walkthrough of a Persimmon client project's pages, data flows, and integrations. Claude leads the user through every route, server action, and external integration — asks them to open each, explains what's happening, verifies understanding, then moves on. Output is a project-map.md doc. Use before client meetings, status emails, onboarding new devs, or when Renato asks "walk me through this project" or "where does X come from." Triggers — "walk me through", "project walkthrough", "guided tour", "project xray", "where does X come from", "how does Y work", "onboard me".

persimmon-automation-labs Skill

Zod validation at every trust boundary on the Persimmon stack. Use when validating Server Action inputs, API route bodies, webhook payloads, search params, environment variables, or any untrusted data crossing into the app. Covers `safeParse` over `parse`, discriminated unions for polymorphic payloads, branded types for IDs, `.transform` for coercion, `@t3-oss/env-nextjs` for typed env, and anti-patterns (throwing in handlers, trusting `request.json()`, using `unknown` without narrowing).

persimmon-automation-labs Skill

Adversarial red-team of an approved-draft spec, between workflow-brainstorm and workflow-plan, on the Persimmon stack. Hunts the failure modes that pass a happy-path read but blow up in production — concurrency/oversell under Server Actions, money-state timing across Stripe webhooks, unverifiable acceptance criteria, Railway/NextAuth cutover landmines, and jurisdiction-specific tax/legal rules. Builds a requirements-traceability matrix (forward + backward) and a short client-question list. Use after workflow-brainstorm writes a spec, before workflow-plan. Trigger keywords: spec review, red-team the spec, is this spec ready, RTM, traceability, oversell, money timing, cutover.

persimmon-automation-labs Skill

Self-service settings & integration-credentials manager for the Persimmon stack — every integration's API keys/IDs/config (Stripe, Twilio, Resend, Google, social) is editable by the client (Owner) through the admin UI. DB-backed via Prisma, secrets encrypted at rest with Node crypto AES-256-GCM, env fallback, per-integration test-connection. Use whenever a build adds any third-party integration. Trigger keywords: settings, integration credentials, API keys, encrypted at rest, env fallback, test connection, self-service config.

rsaccone Bundle

Expert guidance for Swift code quality and refactoring. Use when developers ask for Swift best-practice reviews, style cleanup, readability improvements, API design feedback, optional/error-handling guidance, performance-minded refactors, or production-readiness checks.

roanbrasil Skill

Production-hardened microservices guidance — service decomposition, inter-service communication, API Gateway, distributed tracing, data ownership, and anti-patterns

yalishevant Bundle

Design and generate Kotlin Spring HTTP APIs with correct controller signatures, DTOs, validation, serialization assumptions, error handling, and web tests. Use when building or changing REST endpoints, choosing between MVC and WebFlux, modeling request and response payloads, standardizing error responses, or avoiding Kotlin-specific validation and Jackson mistakes.

yalishevant Bundle

Design resilient HTTP, messaging, and scheduled integrations for Kotlin plus Spring services with explicit timeout budgets, retries, idempotency, circuit breakers, DLQ behavior, and failure observability. Use when integrating with unstable external systems, designing retry logic, handling duplicate delivery, preventing thundering herds, or making message-driven and scheduled workflows safe in production.

yalishevant Bundle

Decompose business scope into bounded contexts, module or service boundaries, workflows, and API contracts before implementation begins. Use when shaping a new feature, service, or major redesign; when requirements are underspecified; when consistency, idempotency, and integration boundaries must be made explicit; or when ADR-quality tradeoff reasoning is needed for Kotlin plus Spring systems.

nisar999 Skill

yalishevant Bundle

Diagnose and design JSON serialization and deserialization behavior for Kotlin plus Jackson in Spring applications. Use when DTOs fail to deserialize, default parameters or nullability behave unexpectedly, date-time or enum formats drift, polymorphic payloads are involved, PATCH semantics must distinguish null from absent, or ObjectMapper changes risk breaking existing API or message contracts.

ouhoy Bundle

Drive a Workato account via its Platform REST API — inspect, build, fix, debug, and start/stop recipes; read connections, folders, projects, jobs. Use when a task touches a Workato account or recipe.

pimenov Skill

Designs stable API, interface, schema, event, CLI, module, and service contracts before implementation so callers, consumers, and future agents can depend on them safely. Use when creating or changing public/internal APIs, SDK surfaces, webhooks, GraphQL/REST/RPC routes, database or message contracts, module boundaries, config formats, CLI commands, or any interface where compatibility, versioning, errors, auth, observability, or Hyrum's Law matters.

pimenov Skill

Breaks large or multi-file implementation work into small verified slices that keep the project working after each step. Use when building a feature, bugfix, refactor, migration, integration, UI flow, or operational change that could become a large diff; when more than one file/module is touched; when scope is fuzzy; when review or rollback would be hard; when Codex is tempted to code for a long time before testing; or when the user asks to work in small verified steps, slices, маленькими проверяемыми шагами, по шагам с проверкой, or после каждого шага проверяй.

On first use the skill walks the user through getting their BOG API credentials, stores them locally, and reuses them afterward. Strictly READ-ONLY: it can never move money, create payments, or sign anything.
