Designs decentralized apps from brief to production — user + trust-boundary mapping, contract architecture, client layer, indexing strategy, off-chain components, deployment pipeline, and ops. Use when starting a new dApp and needing a coherent plan before code, auditing an existing dApp for architectural gaps, or teaching a team to think through dApp design instead of stumbling into it.

Turns one piece of content into multiple surfaces — blog post → Twitter/X thread → LinkedIn post → newsletter issue — matching each platform's conventions. Use when a user has shipped a long-form piece and wants to extract shorter variants for other channels, or is planning a content launch across multiple platforms.

Drafts emails in the right tone and length for the situation — cold outreach, follow-up, introduction, apology, thank-you, difficult conversation. Use when a user needs to write an email they're stuck on, rewrite an email that sounds off, or draft a template they'll reuse for similar situations.

Produces meeting notes that capture decisions and action items — not transcription. Attendees, agenda, decisions, action items with owners and deadlines. Use when a user needs notes from a meeting that's about to happen, is happening, or just ended, or wants a template for recurring meetings.

Produces research briefs that answer a question — sources, synthesis, gaps, recommendation — rather than summaries that describe a topic. Use when a user needs to research a decision, investigate a market or tool, understand an unfamiliar domain quickly, or present findings to a stakeholder who wants an answer, not a report.

Tailors a résumé to a specific job description — parses the JD for priorities, reorders and rewrites bullets to match, quantifies achievements, and passes ATS filters. Use when a user is applying to a specific role and wants their résumé to match the JD, or when their bullets are weak ("responsible for...") and need tightening.

Tightens prose — removes fluff, varies sentence length, prefers concrete verbs, matches a target voice. Use when a user wants to edit or rewrite a draft (email, post, README, memo), when copy reads "AI-generated" and needs to sound human, or when matching a specific writer's voice.

Ready-to-use git recipes for the operations people actually run every day — undoing mistakes, safe rebasing, resolving conflicts, rescuing lost work, and PR-friendly history cleanup. Use when a user asks how to undo a git operation, clean up a branch before merging, recover from a bad push, or make a branch PR-ready.

Copy-ready regex patterns for the 20 strings people actually match every day — emails, URLs, UUIDs, semver, IPs, dates, line-level patterns — plus the building blocks, language-specific pitfalls, and debugging workflow. Use when a user asks for a regex for a common string format, needs to extract or validate something, or is debugging a regex that isn't matching what they expect.

Implements Stripe subscription flows end-to-end — checkout, webhook-driven state sync, cancellation, tier downgrades, and testing. Use when adding paid subscriptions to a new app, migrating from another billing system, or hardening an existing subscription flow that has drifted out of sync with Stripe.

Structures prompts for LLM applications — role usage, delimiters, chain-of-thought, few-shot examples, structured output, prompt caching, and when to stop tuning and reach for RAG or fine-tuning instead. Use when building an LLM feature, rewriting a flaky prompt, moving from a prototype to production, or reviewing prompts in code review.

Audits and implements the technical SEO basics any modern web app should ship with — metadata, structured data, crawlability, Core Web Vitals, and international targeting. Use when launching a new site, auditing an existing one, or reviewing a PR that touches routing, rendering, or head tags.

Scaffolds a Solidity smart contract project — Foundry-first with Hardhat alternative, OpenZeppelin-based token patterns (ERC-20/721/1155), testing, and deployment. Use when starting a new Solidity project, standardizing an existing one, adding a new contract to an existing repo, or migrating from Hardhat to Foundry (or back).

Verifies a deployed Solidity contract on Etherscan (or any Etherscan-compatible explorer) via Hardhat's hardhat-verify plugin, with a manual Etherscan V2 API fallback for cases where the plugin fails. Use when a contract deploy needs verification, when automated verify fails with ABI/constructor/linking errors, or when a contract is flattened or uses custom compiler settings.

Scaffolds a Solana on-chain program with Anchor — workspace setup, PDA patterns, dual SOL/SPL token support, constraint-driven validation, on-chain randomness via SlotHashes, testing with the TypeScript Anchor client, and mainnet deployment. Use when starting a new Solana program, adding a new instruction to an existing one, or standardizing an ad-hoc Anchor project.

Authors new skills for the agent-skills repo with consistent format — tight SKILL.md, frontmatter, references for depth, and a pre-merge checklist. Use when adding a new skill to github.com/Solonnikov/agent-skills, standardizing an existing skill, or auditing a skill's structure.

Reads, writes, and watches EVM smart contracts using wagmi v2 with typed ABIs — simulate/write/receipt pattern, event subscription, and chain-aware error handling. Use when integrating a contract into a frontend, adding a new write flow, extending read calls, or hardening an existing contract interaction against reverts and user rejection.

Scaffolds a complete NgRx feature module (actions, reducer, effects, selectors, facade, models, tests) using modern Angular patterns. Use when adding a new feature slice to an Angular + NgRx app, standardizing existing ad-hoc state code, or bootstrapping state for a new library in an Nx monorepo.

Integrates @reown/appkit multi-chain wallet connections (EVM via wagmi, Solana, Bitcoin) into a web app — initialization, network configuration, connection state, and transaction flows. Use when adding wallet connect support to a new app, extending an existing app to a new chain family, or standardizing wallet state management.
