Build a SaaS app with coding agents on Next.js, Supabase, Clerk and Netlify: the path from idea to production, multi-tenant authorization, the production choices for Supabase and Clerk, environments and secrets, product design, transactional email, uptime monitoring, cookieless analytics, legal pages, remote MCP servers, ChatGPT plugins and embedded Claude agents.
Plugin app-stack from marketplace product-engineering in phuryn/product-engineering. Commands read from the repo's manifest — yesterday.
app-lifecyclePlanning a SaaS stage, 'what's next', 'where are we', calling a stage done: the detailed path from an idea to production, each stage with its done-when.
chatgpt-pluginBefore building, submitting or changing a ChatGPT plugin or Apps SDK app: get it through OpenAI's directory review (auth, package, OAuth, data rules, portal).
clerk-productionSetting up or changing Clerk sign-in, organizations, roles or billing on Next.js, or sign-in that does nothing or lands wrong: Clerk in production.
embedded-agents-agent-sdkOnly when the Agent SDK is asked for, an agent needs Claude Code's own tools, or the app already runs it: embed Claude agents in a Next.js app with the Agent SDK.
embedded-agents-messages-apiBuilding, adding or wiring up an agent or an agent chat inside a Next.js app: embed Claude agents on the Messages API, the default way.
environmentsAdding a variable or secret, 'set up production', a domain or a provider token, 'which database is this', a leaked key: dev and production for an AI-built app, backups, incidents.
legal-pagesPrivacy policy, terms, a cookie banner, consent at sign-up, a public front door: legal pages drafted from what the code does, held to it by a test, with the owner's facts and sign-off.
mcp-serverBefore adding a remote MCP server or tool to a web product, adding OAuth to it, or listing it in a directory: ship it right the first time, tests included.
product-analyticsAdding analytics, session recordings, heatmaps, 'what did users do', Clarity or PostHog: behaviour analytics without analytics cookies, read back by the agent.
saas-authorizationAdding sign-in, a role, a route that touches data, API tokens, a webhook or job, or 'is this secure': who may do what in a multi-tenant SaaS.
supabase-productionA Supabase query, RPC or migration, 'db push', 'supabase link', RLS or grants, a Supabase error: server-only keys, deny-all RLS, migrations via the CLI.
transactional-emailAdding transactional or alert email, choosing a provider, 'sent twice', 'never arrived': app email sent once, never lost, with one-click unsubscribe.
ui-designMandatory for any product's screens, a builder's too, and any mock, prototype or artifact that shows them: its design system, colour, type, components; judging the look.
uptime-monitoringPublishing an app, adding /health or a cron job, 'set up monitoring', 'is it down': content checks, a second location, heartbeats, a tested alert route; Staygreen by default.
Ship AI-built apps: document the app, review it for correctness, security and performance, have a fresh reviewer clear every push that deploys and every release, round after round, prove it with a test harness that fakes the right side, and release through a gate with the owner's go. Where the free pm-ai-shipping plugin moved: turn that one off once this is installed.
11 skills
Decide what to build before building it: find where the work stands, research an idea and propose hypotheses with their sources in one artifact with key screens, then competitors and segments, the value proposition, the value curve, the beachhead segment and growth loops.
8 skills
Make your own agent setup reliable: instruction files that are met at the moment they apply, rules held by hooks instead of prose, status that survives context compaction, the handover the next session starts from, a session's friction turned into a setup fix, and the Windows shell traps that break agents.
6 skills
Work with other coding agents as partners: brief any delegate with the why, and drive the Codex CLI, the Grok CLI or Claude Code headless from another agent as a peer, builder or fresh reviewer. The review loop itself is independent-review, in ai-shipping.
4 skills
Edit AI-sounding work writing so it reads like a careful person wrote it, without changing what it says — or interview the writer and build the piece from their answers.
