Maintains development environment instructions in the project README.md using nixomatic. When the user asks to build, compile, test, lint, format, type-check, run, or set up a project, or when a command fails because a tool or runtime is not installed, analyze project files to determine required packages and use nix develop with a nixomatic.com URL. Ensure the README.md documents how to reproduce the environment with both nix develop and docker run nixos/nix.
Gas optimization patterns for Solidity smart contracts. Use when optimizing contract deployment costs, runtime gas usage, or storage efficiency. Covers storage packing, custom errors, immutable variables, calldata optimization, loop patterns, assembly usage, and Solady gas-optimized alternatives. Triggers on tasks involving gas optimization, storage layout, deployment cost reduction, or EVM efficiency.
Debug and verification workflow for runtime-bundle and module-resolution regressions. Use when diagnosing unexpected module inclusions, bundle size regressions, or CI failures related to NEXT_SKIP_ISOLATE, nft.json traces, or runtime bundle selection (module.compiled.js). Covers CI env mirroring, full stack traces via __NEXT_SHOW_IGNORE_LISTED, route trace inspection, and webpack stats diffing.
DCE-safe require() patterns and edge runtime constraints. Use when writing conditional require() calls, guarding Node-only imports (node:stream etc.), or editing define-env-plugin.ts / app-render / stream-utils for edge builds. Covers if/else branching for webpack DCE, TypeScript definite assignment, the NEXT_RUNTIME vs real feature flag distinction, and forcing flags false for edge in define-env.ts.
Load PROACTIVELY when task involves investigating errors, diagnosing failures, or tracing unexpected behavior. Use when user says "debug this", "fix this error", "why is this failing", "trace this issue", or "it's not working". Covers error message and stack trace analysis, runtime debugging, network request inspection, state debugging, performance profiling, type error diagnosis, build failure resolution, and root cause analysis with memory-informed pattern matching against past failures.
Guide for using mise to manage development tools and runtime versions. Use when configuring project tooling, managing environment variables, or defining project tasks.
Create new agent skills with best-practice templates. Guides through skill level selection (L0 pure prompt, L0+ with helper scripts, L1 with business scripts), environment strategy (stdlib/uv/venv), and generates ready-to-edit project files following runtime UX best practices. This skill should be used when creating a new skill, scaffolding a skill project, initializing skill templates, or when the user says 'help me build a skill', 'create a skill', '创建技能', '新建 skill'.
Invoked when user wants to implement specific state modules in TypeScript for Bun runtime environment in GraphiCode-managed projects. Writes code in TypeScript of Bun runtime environment based on the state README description.
Use when working with Bun's runtime APIs including file I/O, HTTP servers, and native APIs. Covers modern JavaScript/TypeScript execution in Bun's fast runtime environment.
Enterprise session state management, token budget optimization, runtime tracking, session handoff protocols, context continuity for Claude Sonnet 4.5 and Haiku 4.5 with context awareness features
iOS debugging and troubleshooting skills. Used when users need to investigate and diagnose issues such as crashes, exceptions, runtime errors, memory leaks, memory growth, unreleased ViewController, UI lag, frame drops, slow startup, etc. Provides crash type identification, root cause analysis, LLDB commands and repair solutions.
Fastify high-performance Node.js framework. Covers routing, plugins, validation, and serialization. Use when building fast Node.js APIs. USE WHEN: user mentions "Fastify", "fastify", "TypeBox", "schema validation", asks about "fast Node.js framework", "high-throughput API", "JSON schema validation", "performance-critical backend", "plugin-based architecture" DO NOT USE FOR: Enterprise DI patterns - use `nestjs` instead, Minimalist approach - use `express` instead, Edge runtimes - use `hono` instead, Deno - use `oak` or `fresh` instead
