vercel-react-best-practices
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
slop-check
Strip agent-generated noise from a diff — comments that restate the code, private helpers in test files, near-duplicate tests, tests with no assertions, unrequested indexes and validation, defensive guards that duplicate an existing check. Use before opening a PR on agent-written code, or when the user asks to tighten a diff, remove slop, or cut verbose comments.
reuse-check
Check a diff for code that reinvents something Polar already has — a kit helper, a shared Pydantic type, a repository method, an Orbit component, an existing model property. Use before opening a PR, when reviewing a diff, or when the user asks whether a new helper, validator, type or utility already exists in the codebase.
ship-safety
Check whether a diff is safe to deploy — schema changes that break the currently running code, blocking DDL, renaming or moving background task actors while jobs are in flight, queue priority, cron catch-up, locking, batch size, and whether the change should be split into more than one PR. Use before merging a PR that touches migrations, tasks.py, models, or removes an endpoint.
open-pr
Open or update a draft GitHub pull request after Polar-specific review and cubic CLI review. Use only when the user invokes open-pr, /open-pr, or $open-pr by name. Do not use for a plain request to open a PR, or for a host Create PR button.
polar-code-review
Review a Polar branch diff against conventions, Accepted ADRs, reuse, slop, and path-triggered API, ship-safety, and billing lenses. Use before opening a PR, when the user asks for a Polar code review, /polar-code-review, or $polar-code-review. Not a bug hunt or security review.
render-env
Add a new Terraform Cloud variable for the Render-hosted backend across production, sandbox, and test. Declares the tfe_variable in terraform/global/{production,sandbox,test}.tf and the matching variable {} block in terraform/{production,sandbox,test}/variables.tf, then reminds the user to wire it into render.tf / the render_service module.
add-locale
Add a new translation locale to the Polar frontend. Walks through registering the locale, generating translations, wiring the generated file into the i18n package, and updating the public-facing docs. Expects the target locale's ISO 639-1 alpha-2 code (optionally with a BCP-47 region suffix, e.g. `pt-PT`).
api-surface-review
Review changes to Polar's API contract — Pydantic schemas, FastAPI endpoints, OpenAPI output and the generated SDKs. Checks public vs private exposure, schema shape and naming, and whether the change breaks merchants or the generated clients. Use when a diff touches schemas.py, endpoints.py, docs/openapi.json or sdk/, or when the user asks whether an API change is breaking.
adr-check
Check a code change against the repo's Accepted Architecture Decision Records (ADRs) in handbook/engineering/decisions/ and report violations with citations. Use before opening a PR, when reviewing a diff, or when the user asks to check ADR compliance, whether changes follow the architecture decisions, or to verify a change against the ADRs.
conventions-check
Check a diff against Polar's written conventions in server/AGENTS.md and clients/AGENTS.md — module structure, repository and service patterns, session types, auth dependencies, test organisation, Orbit Box usage, i18n placement. Use before opening a PR or when the user asks whether a change follows Polar's conventions.
fix-sentry
Analyze and fix issues reported by Sentry in the Polar codebase.
billing-review
Review a diff that touches Polar's billing domain — subscriptions, cycles and crons, orders, billing entries, meters and usage, discounts, checkout, payments and dunning, refunds, disputes, payouts, wallets, tax and invoices. Use before opening a PR that changes money movement or subscription lifecycle, when the user asks for a billing review, or when a reviewer needs the domain rules the team enforces in review but that no linter catches.
doc-sync
Keeps IdeaVim documentation in sync with code changes. Use this skill when you need to verify documentation accuracy after code changes, or when checking if documentation (in doc/, README.md, CONTRIBUTING.md) matches the current codebase. The skill can work bidirectionally - from docs to code verification, or from code changes to documentation updates.
tests-maintenance
Maintains IdeaVim test suite quality. Reviews disabled tests, ensures Neovim annotations are documented, and improves test readability. Use for periodic test maintenance.
git-workflow
IdeaVim git workflow conventions covering commits, branches, PRs, and CI. Use when creating commits, managing branches, creating pull requests, reviewing git history, or any git-related activity in the IdeaVim project.
issues-deduplication
Handles deduplication of YouTrack issues. Use when cleaning up duplicate issues, consolidating related bug reports, or organizing issue tracker.
extensions-api-migration
Migrates IdeaVim extensions from the old VimExtensionFacade API to the new @VimPlugin annotation-based API. Use when converting existing extensions to use the new API patterns.
changelog
Maintains the IdeaVim changelog (CHANGES.md). Use when updating the changelog, documenting releases, or reviewing commits/PRs for changelog entries.
frontend-dev-guidelines

Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, MUI v7 styling, TanStack Router, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.
error-tracking
Add Sentry v8 error tracking and performance monitoring to your services. Use this skill when adding error handling, creating new controllers, instrumenting cron jobs, or tracking database performance. ALL ERRORS MUST BE CAPTURED TO SENTRY - no exceptions.
backend-dev-guidelines
Comprehensive backend development guide for Node.js/Express/TypeScript microservices. Use when creating routes, controllers, services, repositories, middleware, or working with Express APIs, Prisma database access, Sentry error tracking, Zod validation, unifiedConfig, dependency injection, or async patterns. Covers layered architecture (routes → controllers → services → repositories), BaseController pattern, error handling, performance monitoring, testing strategies, and migration from legacy patterns.
skill-developer
Create and manage Claude Code skills following Anthropic best practices. Use when creating new skills, modifying skill-rules.json, understanding trigger patterns, working with hooks, debugging skill activation, or implementing progressive disclosure. Covers skill structure, YAML frontmatter, trigger types (keywords, intent patterns, file paths, content patterns), enforcement levels (block, suggest, warn), hook mechanisms (UserPromptSubmit, PreToolUse), session tracking, and the 500-line rule.
source-command-verify-setup
