Test-driven development, red then green, one vertical slice at a time. Use when building a feature, a rule, a config option or a bug fix test-first, when the user says "TDD", "red-green" or "write the test first", or when a subagent is handed a ticket to build.

Investigate a question against primary sources and capture the findings as one cited Markdown note. Use when the user wants a topic researched, a vendor's docs or API facts gathered, a library's or tool's real behavior confirmed, or reading legwork delegated while the main session keeps working.

Review a finished coding session for what slowed the agent down or let a mistake through, and turn one lesson into a test, check or doc in the project so the next session does not repeat it. Use when the user asks for a retro or retrospective, a post-mortem of a session, or "what should we change so this doesn't happen again". To carry unfinished work into a new session, use `handoff`; to prove a fix before claiming it, use `regression-proof`.

Runs Cloudflare's security-audit skill in full audit mode from Claude Code. It builds each agent's prompt file from that skill's text, pulls each agent's JSON reply out of its transcript, and keeps the coverage ledger, findings, agent-call budget and NEEDS-VALIDATION.md. Use it together with `security-audit` when the user asks for a full, end-to-end or report-producing security audit or pen test of a codebase. For a security question or a focused review, use `security-audit` alone.

Find skills whose descriptions fight over the same request, so Claude picks one at random or the wrong one, and fix the descriptions. Use when the user asks to audit, clean up or deduplicate their skills, when a skill fires that should not have, after installing a plugin, or before adding a new skill to a large library.

Route a multi-step task across cheaper subagents while the main session keeps the plan, the judgment calls and the verification. Use at the start of any task with more than one step, before spawning a subagent, when picking a model for a subtask, when a subagent fails, or when the user mentions cost, tokens or model choice.

Shorten an existing ticket that is too long or too technical, moving the engineering detail into a Technical notes comment so nothing is lost. Use when the user gives a ticket key or link and asks to trim, condense, simplify or clean it up, or says a product owner or analyst found it hard to read.

Writing documents for agents. Use when creating or editing a skill (its SKILL.md, description or reference files), when modifying AGENTS.md or CLAUDE.md, or when reviewing an agent-facing document that behaves inconsistently across runs. Prose that people read, such as a memo or a one-pager, follows its own rules.

About 450 ready-made HyperFrames blocks and components installed as editable source - transitions, overlays, titles, kinetic type, captions, charts, map overlays, 3D, camera moves. Use it before hand-building any named visual (CRT scanlines, glitch, film grain, a chart); also for hyperframes add and catalog.

Postgres best practices maintained by Supabase, for Postgres running anywhere. Load this skill BEFORE writing or changing anything that lives in a Postgres database: creating or altering tables and columns (including choosing column types), schema design, migrations and declarative schema files, RLS policies and the tests that verify them, indexes, triggers, database functions, queues and scheduled jobs (pg_cron, pgmq), vector/semantic search (pgvector), and restoring dumps (pg_restore) or importing data. Also load it when diagnosing slow queries, high CPU, timeouts, EXPLAIN plans, connection exhaustion, locking, bloat, or rows visible to the wrong user or tenant. This is not just a performance guide — schema, migration, security, and SQL authoring tasks need these rules too, even for a one-column change or a single query.

Deprecated compatibility name for prisma-orm-setup. Use only when a user or existing integration explicitly invokes prisma-database-setup; otherwise select prisma-orm-setup.

Deprecated compatibility name for prisma-postgres-setup. Use only when a user or existing integration explicitly invokes prisma-postgres; otherwise select prisma-postgres-setup.

Obtain or reuse a Prisma Postgres database and connect an application. Use when the user needs a database and has none configured ("I need a database", "add a Postgres database", "set up a database for this app"), runs or mentions `create-db` or `npx create-db`, or asks to set up or connect Prisma Postgres, including in v0 and the Vercel Marketplace. Hands Prisma ORM configuration to prisma-orm-setup; reuses an existing connection first and honors an explicit provider, driver, alternative ORM, or database-only choice.

Required reference for Prisma ORM 7 SQL driver adapter work. Use when implementing or modifying adapters, adding database drivers, or touching SqlDriverAdapter, Transaction, savepoint, result mapping, or DriverAdapterError behavior. Covers current transaction lifecycle, optional savepoint hooks, original database-error preservation, and verification.

Use when doing ANY task involving Supabase. Triggers: Supabase products (Database, Auth, Edge Functions, Realtime, Storage, Vectors, Cron, Queues); client libraries and SSR integrations (supabase-js, @supabase/ssr) in Next.js, React, SvelteKit, Astro, Remix; auth issues (login, logout, sessions, JWT, cookies, getSession, getUser, getClaims, RLS); Supabase CLI or MCP server; schema changes, migrations, declarative schemas, security audits, Postgres extensions (pg_graphql, pg_cron, pg_vector); debugging and troubleshooting errors or unexpected behavior on Supabase projects (HTTP errors, Postgres errors, RLS surprises, permission denied, schema cache issues, timeouts, Edge Function crashes, Realtime drops, Storage failures) and reading or querying logs (Logs Explorer, ClickHouse).

Set up Prisma ORM in an application, connect its database, or troubleshoot the connection of an existing Prisma 6, 7, or 8 app. Defaults new applications to Prisma ORM 8 and loads the package-owned prisma-8 skill; keeps existing Prisma 6/7 apps on their version with provider references for PostgreSQL, MySQL, SQLite, SQL Server, CockroachDB, MongoDB, and Prisma Postgres.
