Skill: Modern IaC Patterns — Pulumi, AWS CDK, Bicep, cdktf
Create and update pitch decks, one-pagers, investor memos, accelerator applications, financial models, and fundraising materials. Use when the user needs investor-facing documents, projections, use-of-funds tables, milestone plans, or materials that must stay…
Draft cold emails, warm intro blurbs, follow-ups, update emails, and investor communications for fundraising. Use when the user wants outreach to angels, VCs, strategic investors, or accelerators and needs concise, personalized, investor-facing messaging.
Conduct market research, competitive analysis, investor due diligence, and industry intelligence with source attribution and decision-oriented summaries. Use when the user wants market sizing, competitor comparisons, fund research, technology scans, or…
MLOps lifecycle patterns — experiment tracking (MLflow/W&B), model registry, FastAPI serving with canary deployments, drift detection, fine-tuning workflows, retraining pipelines, DVC data versioning, and GPU autoscaling on Kubernetes.
Mobile CI/CD patterns — iOS/Android builds in CI (GitHub Actions/Fastlane), code signing for TestFlight/App Store, automated versioning, screenshot testing, Firebase App Distribution, staged rollouts, and crash-rate gates.
Node.js backend architecture patterns — Express, Fastify, Next.js API routes, TypeScript services. API design, database optimization, caching, middleware. Not applicable to Python, Go, or Java backends.
Privacy engineering patterns — PII classification and inventory, GDPR consent flows, data minimization, right-to-erasure implementation, pseudonymization/encryption, privacy-by-design architecture, and DPIA checklist.
SDK design patterns — API ergonomics, backward compatibility (semantic versioning, deprecation), multi-language SDK generation (openapi-generator vs Speakeasy), error hierarchy design, SDK testing strategies, and documentation as first-class SDK artifact.
Research-before-coding workflow. Search for existing tools, libraries, and patterns before writing custom code. Invokes the researcher agent.
Security patterns for Web3 and blockchain applications — Solana wallet signature verification, transaction validation, smart contract interaction security, and checklist for DeFi/NFT features.
Scan your Claude Code configuration (.claude/ directory) for security vulnerabilities, misconfigurations, and injection risks using AgentShield. Checks CLAUDE.md, settings.json, MCP servers, hooks, and agent definitions.
Suggests manual context compaction at logical intervals to preserve context through task phases rather than arbitrary auto-compaction.
Pattern for progressively refining context retrieval in multi-agent workflows — avoids context-overflow failures when subagents cannot predict what context they need upfront.
Team Workflow OS — shared clarc setup for engineering teams. Covers shared rules distribution, private skill packs, team sync patterns, onboarding, and multi-developer conventions.
WebRTC patterns — peer connection setup, ICE/STUN/TURN configuration, signaling server design, SFU vs mesh topology, screen sharing, media track management, and reconnect/ICE restart handling.
Zero-Trust security patterns — mTLS between microservices (Istio/SPIFFE), SPIRE workload identity, OPA/Envoy authorization, NetworkPolicy default-deny-all, short-lived credentials, service mesh security, and Kubernetes RBAC hardening.
Advanced API contract patterns — AsyncAPI 3.0 for event-driven systems and Consumer-Driven Contract Testing with Pact. Use after the core Contract-First workflow in api-contract.
Contract-First API design — write OpenAPI 3.1 or AsyncAPI 3.0 specs before implementation, generate or validate code against them, detect breaking changes in CI, and apply Consumer-Driven Contract Testing with Pact.
Advanced C++ testing patterns — parameterized tests, death tests, advanced gmock, matchers, test data factories, async/concurrent testing, CI/CD integration, Catch2, and anti-patterns. Use after mastering the basics in cpp-testing.
Use only when writing/updating/fixing C++ tests, configuring GoogleTest/CTest, diagnosing failing or flaky tests, or adding coverage/sanitizers.
Full lifecycle management for clarc instincts — capture, scoring, decay, conflict resolution, promotion, and removal
Full product development lifecycle from raw idea to shipped implementation. Covers idea capture, evaluation (Go/No-Go), solution design (ADR), PRD writing, and handoff to the implementation pipeline. Prevents building the wrong thing.
Strategic Domain-Driven Design — Subdomain classification (Core/Supporting/Generic), Context Mapping (7 relationship patterns), Bounded Context design, and Event Storming. Language-agnostic. Use when designing system boundaries, decomposing a monolith, or…
