Go Development and Debugging
Writes, debugs, and reviews Go: goroutine leaks, data races, nil interfaces, slices and maps, go.mod, and net/http. Use when Go panics or misbehaves — "all goroutines are asleep - deadlock!", "concurrent map writes", "send on closed channel", "assignment to entry in nil map", or a WARNING: DATA RACE from `go test -race`; when a goroutine, timer, or connection leaks and memory climbs; when a service hangs for want of a timeout; when errors.Is or errors.As stops matching after a %v wrap; when a slice mutates its parent, a map iterates in a new order, or a typed nil returned as error compares non-nil; when go.mod, go.sum, workspaces, replace, or a /v2 path fight over dependencies; when cross-compiling, cgo, build tags, go:embed, or a static container binary fail; when tests are flaky under -race or -parallel or benchmarks lie; when GOGC, GOMEMLIMIT, GOMAXPROCS, or escape analysis need tuning; or when writing handlers, CLIs, database access, or generics. Not for Kubernetes operators or framework internals.
Bash
Writes, debugs, and hardens Bash shell scripts — quoting, arrays, strict mode, traps, argument parsing, and macOS/Linux portability. Use when writing or reviewing any script, one-liner, cron job, deploy script, container entrypoint, or CI step; when a script breaks on spaces in filenames, exits silently, ignores set -e, hangs, or returns the wrong exit code; when quoting, IFS, globs, arrays, heredocs, process substitution, trap, getopts, or mapfile misbehave; when shellcheck flags SC2086 and friends; when unbound variable, bad substitution, command not found, ambiguous redirect, or unexpected end of file show up; when a script works by hand but fails under cron, systemd, sudo, or a CI runner; or when porting between macOS bash 3.2, GNU/Linux, WSL, and POSIX sh. Not for interactive zsh or fish configuration, not for PowerShell, and not for host-level cron, systemd, or permission failures (linux).
Dask
Distributed computing for larger-than-RAM pandas/NumPy workflows. Use when you need to scale existing pandas/NumPy code beyond memory or across clusters. Best for parallel file processing, distributed ML, integration with existing pandas code. For out-of-core analytics on single machine use vaex; for in-memory speed use polars.
SEO Audit
When the user wants to audit, review, or diagnose SEO issues on their site. Also use when the user mentions "SEO audit," "technical SEO," "why am I not ranking," "SEO issues," "on-page SEO," "meta tags review," "SEO health check," "my traffic dropped," "lost rankings," "not showing up in Google," "site isn't ranking," "Google update hit me," "page speed," "core web vitals," "crawl errors," "indexing issues," "stuck on page 2," "striking distance keywords," "title tag rewrite," "low CTR," "local SEO," "Google Business Profile," or "map pack." Use this even if the user just says something vague like "my SEO is bad" or "help with SEO" — start with an audit. For building pages at scale to target keywords, see programmatic-seo. For adding structured data, see schema. For AI search optimization, see ai-seo.
Save Money
Auto-detect task complexity for Claude models (Haiku + Sonnet). Route simple tasks to Haiku, escalate complex ones to Sonnet. Save 50%+ on API costs. | 適用 Claude 模型（Haiku + Sonnet），自動偵測任務難度，簡單用 Haiku，複雜升級 Sonnet，輕鬆省下 50% 以上的費用。— RULES: Before responding, classify the task. If it matches an escalation trigger, call sessions_spawn with the full task and model anthropic/claude-sonnet-4-20250514 IMMEDIATELY. Do NOT answer complex tasks yourself. ESCALATE: analysis, comparisons, planning, strategy, code >10 lines, reports, proposals, multi-step reasoning, tables, outlines, charts, long writing >3 paragraphs, summarization, long translation. NEVER on Haiku: comparison tables, code >10 lines, multi-step analysis, reports, complex reasoning. STAY on Haiku: factual Q&A, definitions, greetings, reminders, short lookups, casual chat, 1-2 sentence tasks. When in doubt, escalate. Keep Haiku replies concise.
Codex
Use Codex safely for repo-aware coding with explicit approvals, sandbox choices, MCP boundaries, and PR-ready verification workflows.
Stock Earnings Review
依托东方财富数据库，面向沪深京港美五大市场的上市公司/股票，生成业绩点评类输出（含财报分析、业绩解读）。 当用户明确提出业绩点评、财报分析、业绩解读需求，或出现「业绩点评」「财报点评」「业绩分析」「季报/半年报/年报点评」「财务分析」「盈利分析」「业绩解读」等表述时，应触发本 Skill。 用户点名具体公司/股票并希望获得业绩与盈利维度的分析评价时，应触发本 Skill。 即使用户未明说「业绩点评」，只要意图是对该公司财报或业绩作分析解读，也应触发。
codexmonitor
List/inspect/watch local OpenAI Codex sessions (CLI + VS Code) using the CodexMonitor Homebrew formula. Reads sessions from ~/.codex/sessions by default (or via CODEX_SESSIONS_DIR / CODEX_HOME overrides). Requires the cocoanetics/tap Homebrew tap.
Vscode
Configures, debugs, and speeds up Visual Studio Code: settings scopes, launch.json, tasks.json, extensions, keybindings, formatters, and remote work. Use when a setting has no effect because something else overrides it, when format-on-save runs the wrong formatter or two formatters fight, when a breakpoint stays hollow, F5 does nothing, or a debug config will not attach, when a watch task hangs preLaunchTask forever, when the extension host crashes or two extensions collide, when IntelliSense dies and the TypeScript server or Python interpreter stops resolving, when a keyboard shortcut is swallowed by the terminal, when Remote-SSH, WSL, dev containers, or tunnels misbehave, when startup, search, or file watching is slow, or when deciding what belongs in .vscode/ and which extensions a fork like VSCodium or Cursor can install. Not for language semantics (`typescript`, `py`), Docker image authoring (`docker`), or general bug isolation (`debugging`).
Codex Orchestrator
Methodical end-to-end software delivery orchestrator for Codex CLI with dual project modes (greenfield for new builds, brownfield for existing systems) and dual execution modes (autonomous and gated). Use when users want full lifecycle delivery with strict stage gates, progress tracking, per-step manual/automated testing, continuous docs updates, change-impact management, and a reusable AGENTS.md workflow for any coding agent.
