Guide to creating a production-ready Web3 wallet app supporting G Coin on PlayBlock chain (ChainID 1829), including architecture, code delivery, deployment, and monetization strategies.
AST-based code pattern analysis using ast-grep for security, performance, and structural issues. Use when (1) reviewing code for security vulnerabilities, (2) analyzing React hook dependencies or performance patterns, (3) detecting structural anti-patterns across large codebases, (4) needing systematic pattern matching beyond manual inspection.
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Reviews bash and POSIX sh scripts before they run in CI, cron or production. Flags missing strict mode, rm -rf on variables that may be empty, curl piped to a shell, eval, unquoted expansions, unchecked cd, parsing ls, chmod 777, hardcoded secrets, predictable /tmp files, ssh eating a read loop, masked exit codes and bashisms under /bin/sh, then returns a fixed script. Includes a stdlib Python linter with --self-test.
Reviews GitHub Actions workflow YAML for supply-chain and injection risks: pull_request_target with PR checkout, untrusted github.event text in run steps, actions pinned to tags or branches instead of commit SHAs, missing or write-all permissions, secrets in shell commands, curl | bash, self-hosted runners on PRs, and missing timeouts. Use before merging CI changes or auditing a repo. Includes a stdlib Python linter with --self-test.
