Agent Claude Code
Use this agent when the user needs deep investigation on a topic, technology, library, API, market data source, academic papers (arXiv/SSRN), or any subject requiring web research.
Skill Claude Code
Inspect or debug web pages in a headless browser — fill forms, click buttons, take screenshots, test web apps, review frontend UI/UX aesthetics. Use for headless browser automation. This skill should be used when user says "test web app", "headless browser", "browser automation", "chromium --headless", "screenshot of…
Skill Claude Code
Translate natural language queries into ast-grep rules for structural code search. This skill should be used when a text-only grep would need 2+ alternations, regex capture groups, multi-line patterns, or filtering by syntactic role (call vs. import vs. definition). Also use when renaming a symbol across call sites +…
Skill Claude Code
Run long-running tasks under babysit — supervised background runner with cgroup-enforced memory/CPU caps and observability-stall kill. Use BEFORE any long-running task (>2 min), compute-intensive jobs (e.g. builds/benchmarks/renders/training), background work, or when the user says "run in background", "use babysit".…
Skill Claude Code
Translate English into Chinese in natural human voice. Use before writing or polishing any Chinese translation of English content.
Skill Claude CodeCodex
Connect to user's local Chrome session. Inspect and interact with web pages in a headful browser shared with user cookies and login states — navigate pages, click buttons, take screenshots, test web apps in headful Chrome the user could see in real-time. Use for headful browser automation. This skill should be used…
Skill Claude CodeCodex
Send peer-to-peer message and control to Claude Code sessions. Use when coordinating multiple simultaneous Claude sessions, or user says "dm another claude", "list claude sessions", "peek peer claude", "spawn claude in tmux", "monitor remote claude", "notify peer in tmux", "send to peer", "handover to claude"…
Skill Claude CodeCodex
Programmatic/headless Claude Code usage — CLI flags, stream-json protocol, Agent SDKs, session management. Use before spawning Claude as a subprocess, testing skill or agent behavior, running "claude -p", or building with the Agent SDK.
Skill Claude Code
Fetch current docs and code examples for third-party libraries, SDKs, APIs, and CLI tools via Context7. Use before writing or editing non-stdlib library calls — your prior knowledge may be stale. Prefer over web search for library docs.
Skill Codex
Evidence-driven C++ high-performance computing design, profiling, and optimization across algorithmic time/space complexity, data layout, cache and memory behavior, numerics, SIMD, multicore scheduling, and CPU/accelerator pipelines. Use before designing or changing computation-intensive kernels, high-throughput data…
Skill Codex
High-quality C++ OOP coding style (archibate / parallel101 lineage) that overrides sloppy AI-default C++. Use this skill WHENEVER writing, editing, refactoring, or reviewing C++ code (.cpp / .h / .hpp / .cc / .cxx), designing C++ classes, interfaces, APIs, or libraries, or when the user mentions C++ design, OOP…
Skill Claude Code
Architecture design reasoned forward from requirements. Use when the user wants a fresh-mind design pass — "design an architecture for", "how would you build", "redesign from scratch" — or when repeated follow-up patches accumulate on the same module. Repeated follow-up patches landing on the same module (3rd) → stop…
Skill Claude Code
Code search across millions of public GitHub repositories via grep.app. Use before writing or planning code to find real-world usage of libraries, frameworks, APIs, algorithms, or syntax patterns. Prefer this over web search for code examples.
Skill Claude Code
Interview the user about a plan or design until reaching shared understanding. This skill should be used when the user wants to stress-test a plan, get grilled on their design, or mentions "interview me".
Skill Claude Code
Web search with time-window, region/language, and site: filters, academic papers (arXiv/SSRN), PDF table/figure extraction, BibTeX, image search, web page reading, embeddings, reranking, classification, and deduplication (text or images) via Jina AI. Use when searching web content, finding academic papers, or…
Skill Claude Code
Append a single bullet to staging memory. Use when a durable fact, knowledge, lesson, or pitfall (mistake-correction pattern) emerged mid-conversation that's potentially worth persisting into long-term memory. Also use when user corrected your mistake, says "remember X", "remember not to X", or "next time, do Y…
Skill Claude Code
Form a minimal self-contained prompt to reproduce this session. Use when user want to form a minimal spec of existing system, or when they migrate from a degraded session to a fresh one.
Skill Claude Code
Add a note only visible to user. A private scratchpad not visible in agent context.
Skill Claude Code
One sentence output style.
Skill Claude Code
Extract clean, complete markdown from any web page — articles, docs, READMEs, blog/social posts, academic papers. Also use as a fallback when curl returns noisy HTML or WebFetch returns truncated, summarized, or refused results.
Skill Claude CodeCodex
Clone or reuse a cached local checkout of a remote git repo (GitHub/GitLab/Bitbucket). Use when the user gives a repo URL or owner/repo identifier (e.g. "facebook/react"), says "clone this repo" / "read the source", or needs to browse a remote codebase.
Skill Claude CodeCodex
Scrape, crawl, or extract data from websites using Scrapling — anti-bot bypass (Cloudflare Turnstile), stealth headless, spiders, adaptive scraping, JS rendering. Also a fallback when WebFetch fails due to anti-bot protections or JS rendering.
Skill Claude Code
Create, edit, and benchmark agent skills — including evals with variance analysis and optimizing a skill's description for triggering accuracy.
Skill Claude CodeCodex
Spawn and interact with interactive CLIs (python, gdb, etc.) in tmux — send keystrokes, scrape pane output. This skill should be used when running any interactive CLI command, starting program requires interactive stdin / PTY / TUI render, or when the user says "split pane", "run in tmux", "start REPL", "spawn in…
