Claude Skills

What's New

Skills 17–19 + integration arc (2026-06)

• Skill 17 — Non-Engineering Verticals — C-suite personas, finance domain, compliance OS, PM domain. One OS, every function.
• Skill 18 — Document Processing — DOCX/XLSX read-write, PDF generation + parsing, PPTX generation. Full pipeline, no manual exports.
• Skill 19 — MCP Authoring — forge HTTP MCP servers on Workers, stdio MCP templates, OpenAPI→MCP forger. Publish to the registry in one command.
• 20+ slash commands — /saas, /forge-from-openapi, /forge-webhook-handler, /generate-prp, /execute-prp, /run-evals, /audit-doctrine, /audit-mcp-fleet, /dashboard-cockpit, /drift-check, and more.
• Production forge script — bin/forge-skill-from-openapi.mjs generates a full SKILL.md + command scaffold from any OpenAPI spec.
• LLM eval harness — /run-evals + structured rubrics + schema-validated results + regression tracking. AI-heavy behavior now has a repeatable quality gate.
• 15 new doctrinal principles — state-is-the-enemy, fail-fast-build-fail-soft-prod, ttfr-north-star, sync-ui-async-backing, cost-per-request-accountability, inverted-abstraction-pyramid, one-way-two-way-doors, vendor-risk-tiering, data-residency-by-default, right-to-deletion, refund-automation, documentation-as-code, production-observability-default-on, hardware-aware-programming, webhook-receiver-architecture.
• DO agent scaffolding — Durable Objects as stateful AI agents via skill 19, wired to the MCP registry.
• RAG pipeline — vectorize + D1 hybrid search documented in skill 05 architecture submodules.
• Multi-tenant subdomain provisioning — Cloudflare custom hostnames + per-tenant D1 namespacing, baked into skill 05.
• 5 new PreToolUse hooks — permission-discipline enforcement before destructive tool calls.
• MCP server registry — /audit-mcp-fleet catalogs, health-checks, and version-pins every MCP in your harness.

Hard Gates

Every deploy must clear all gates. No exceptions. No overrides.

Task Routing

The router loads the smallest useful subset per task — never the full 163 docs. See _router.md for the complete routing table. This plugin ships 163 reference docs across 19 skill categories.

Ideal Prompts

Copy-paste these as-is. Each one routes through the skill graph and produces a deployed, gate-cleared product. The shorter the prompt, the more the skill engine infers — domain name alone is enough.

Build a SaaS from a domain

Build acmebilling.dev — recurring subscription billing for indie SaaS founders. Stripe-native, Clerk auth, Inngest for retry workflows.

• Skills — 01 → 02 → 03 → 05 → 06 → 07 → 08 → 13
• Agents — architect (Opus) → 5 parallel build agents → deploy-verifier + seo-auditor + visual-qa
• Gate fires — API Key Gate checks STRIPE_*, CLERK_*, INNGEST_*, CLOUDFLARE_API_KEY (global) before any scaffold
• Output — live Worker on acmebilling.dev with checkout, dashboard, webhook handler, Sentry + PostHog + GA4 wired

Rebuild an existing site

Rebuild brianzalewski.com — pull current site from Wayback if dead, keep every page, modernize design, ship to CF Workers.

• Skills — 01 → 02 → 09 (brand extraction) → 15 (full corpus + media+video extraction + grammar audit) → 07 → 08
• Agents — architect → content-writer + visual-qa + seo-auditor
• Gate — every original URL = 200 or 301; logo retention; theme match; favicon set via real-favicongenerator

Spin up a portfolio from one line

Make me a portfolio site at brian.dev — I'm a principal engineer, AI builder, Megabyte Labs founder.

• Skills — 01 → 02 (founder inference) → 09 → 10 → 11 → 12 → 14 (auto-suggests project tiles + impact stats) → 07 → 08
• Optional pairing — if a flagship SaaS exists, portfolio links to it as primary work
• Output — dark-first single-page with hero + work + writing + contact

Local-business site (NAP + reviews + map)

Build paterson-dental.com — family dental practice in Paterson NJ, online booking, insurance verification, Spanish/English.

• Skills — 01 → 02 → 09 → 10 → 13 (local conversion patterns: phone_click, direction_click, booking_click)
• Gate — GOOGLE_MAPS_API_KEY + GOOGLE_PLACES_API_KEY required
• Output — full-width Maps embed, NAP schema.org LocalBusiness, OpenTable/Booksy embed, Twilio SMS booking

Non-profit with donation flow

Build sjsk.org — community clothing distribution for SJSK in Newark, donor portal, impact counter, tax receipt PDFs.

• Skills — 01 → 02 → 09 → 13 (Stripe-first GiveDirectly UX)
• Gate — STRIPE_* keys
• Output — Donate CTA in nav, recurring + one-time, Resend tax receipts, impact counters with IO+rAF roll-in

Brainstorm before you build

What's the highest-ROI thing I can ship this week? Read PORTFOLIO.md, scan current projects, propose 3 ideas with confidence scores.

• Skills — 14 (idea engine) → bounded web research → self-critique filter
• Output — 3 evidence-backed proposals with apa_citation per claim, viral coefficient + AI search visibility scoring, auto-implements confidence ≥ 0.85 aligned ideas

Add a feature to an existing project

Add a magic-link auth flow to acme.dev — passwordless email via Resend, Clerk session, redirect to /dashboard.

• Skills — 05 (architecture decision) → 06 (build slice) → 07 (Playwright E2E homepage-first)
• Agents — test-writer (failing test FIRST) → implementation → deploy-verifier

Debug a wedged pipeline

projectsites.dev workflow stuck on site_id 47 for 3 hours. Diagnose, fix, retrigger.

• Skills — 08 (deploy/runtime) → 07
• Rule loaded — failed-pipeline-protocol.md (5 canonical failure modes)
• Sequence — detect via D1 query → diagnose root cause (CHECK constraint? timeout? OOM?) → fix → verify in isolation → mint session → retrigger via direct worker URL → background monitor

Ship a content-driven blog at scale

Generate 50 programmatic SEO pages for acme.dev — integration|comparison|use-case|template|location templates, GEO-optimized, citations.

• Skills — 09 (pSEO 5 types + GEO + sourced facts via APA citations) → 06 → 07
• Output — 50 unique routes, no templated copy, every quantitative claim cites APA 7th source, Schema.org Article with citation:CreativeWork[]

One-line magic

ghost.megabyte.space

• Skills — 01 (one-line prompt mode inference) → 02 → 05 → 09 → 10 → 11 → 12 → 07 → 08
• Domain alone routes to a complete product
• Gate fires
• Brand extracted from existing infrastructure
• Curated dark/neon aesthetic from ~/Snapchat/best/ 622-shot reference
• Logo from Ideogram
• Deployed to CF Workers

Prompt patterns that work

Philosophy

• Distribution > Technology — The best tool nobody knows about is the worst tool. Auto-create repos for new skills. Integrate into every ecosystem. Broadcast widely.
• Boil the Lake — When completeness costs minutes more than a shortcut, do complete. Boil lakes, flag oceans.
• TDD Always — Failing test first → implement → pass. Real user flows. Homepage first. Click through UI. Never page.goto() for internal navigation.
• One Person + AI = Twenty — The barrier is gone. What remains is taste, judgment, and willingness to do the complete thing.

Can You Make This Better?

Seriously — open an issue or submit a PR. Some things we're thinking about:

• More skill categories? Is 15 the right number or are we missing something?
• Better agent routing? Should model assignments shift as Claude evolves?
• Templates you wish existed? What boilerplate do you write over and over?
• Skills for other stacks? This is CF Workers + Angular today. What else?
• Prompting patterns that consistently produce better results?

If you've built something similar, stolen ideas from here, or just have opinions — we want to hear it. The whole point is that this gets better every day.
