Apply vertical (domain-first) codebase architecture to any project. Use this skill whenever a user asks where to put a file, how to structure a codebase, how to organize code by feature or domain, how to refactor a "horizontal" structure (components/, hooks/, utils/, types/), or asks about code colocation, monorepo boundaries, shared code, or module ownership. Also trigger when the user creates a new module and needs to decide where it belongs, or when reviewing a PR that touches file organization. Works for any language or framework (Python, TypeScript, Go, Rust, etc.) — not just React or frontend.
Use when writing server-side code with Supabase — Edge Functions, Hono apps, webhook handlers, or any backend that needs Supabase auth and client creation. Trigger whenever the user imports from `@supabase/server`, mentions `supabase/server`, Supabase Edge Functions, or needs server-side auth (JWT verification, API key validation, CORS handling) with Supabase. Also trigger when you see legacy patterns in existing code — `Deno.serve`, `createClient(Deno.env.get('SUPABASE_URL'))`, imports from `esm.sh/@supabase`, `deno.land/std` serve, or usage of `SUPABASE_ANON_KEY` / `SUPABASE_SERVICE_ROLE_KEY` — these indicate code that should be migrated to this package.
StartupBase platform help — community-driven startup discovery directory with free dofollow backlinks (DR39). Covers submission process (social auth, tech startups only), review queue (2-3 months free, 24-hour premium), selection criteria (custom domain, public product, never previously featured), weekly Spark newsletter, market categories, and comparison with other directories. Use when your startup needs more visibility and early adopter traffic, you want the DR39 dofollow backlink from StartupBase, your submission keeps getting rejected, or the review queue is taking too long. Do NOT use for multi-directory launch strategy (use /sales-launch-directory). Do NOT use for Product Hunt launches (use /sales-producthunt).
ClickHouse queries, Goose migrations, chdb test schema, Weaviate collections/migrations, or telemetry storage paths.
Run large codebase migrations and multi-file refactors. Uses the Composio CLI to coordinate issue tracking, batched PRs, and CI verification while the agent executes the transforms locally across hundreds of files.
MUI Base UI unstyled React components with Floating UI. Use for accessible components, Radix UI migration, render props API, or encountering positioning, popup, v1.0 beta issues.
Create and edit Obsidian Bases (.base files): Obsidian's native database layer for dynamic tables, card views, list views, filters, formulas, and summaries over vault notes. Triggers on: create a base, add a base file, obsidian bases, base view, filter notes, formula, database view, dynamic table, task tracker base, reading list base.
Rebase E2E test snapshots based on failed tests from the PR comments.
Flaky test fix pattern - replaces arbitrary timeouts with condition polling that waits for actual state changes.
This skill should be used when troubleshooting Firebase emulator issues, rules violations, function errors, auth problems, or deployment failures. Triggers on "error", "not working", "debug", "troubleshoot", "failing", "broken", "permission denied", "emulator issue".
Query SQLite, PostgreSQL, and MySQL databases and export results to CSV/JSON. Use when: (1) Extracting data for reports, (2) Database backup and migration, (3) Data analysis workflows, or (4) Automated database queries.
Use when you want to look up, map, and search for short genetic variants (SNPs, indels) in NCBI's dbSNP database. Resolves between rsIDs, genomic coordinates in VCF format, and HGVS strings. For an rsID, returns variant type, gene associations, clinical significance, allele frequencies, and genomic coordinates (GRCh38).
