Check SSL/TLS certificates for any hostname — expiry dates, issuer, SANs, protocol version, cipher suite. Use when asked to check if a certificate is valid, see when a cert expires, inspect TLS details, or audit HTTPS security. Alerts on expired or soon-to-expire certs. Zero dependencies — pure Python ssl/socket.

Monitor remote servers via SSH — check service health (PM2, systemd, Docker), database status (MongoDB, MySQL, PostgreSQL), disk space, memory, and auto-restart crashed services. Sends alerts via messaging. Use when asked to check server status, monitor services, restart crashed processes, or set up server health checks.

Deep SRE workflow—SLOs/SLIs, error budgets, alerting, toil reduction, incident readiness, capacity, and balancing reliability with delivery. Use when improving production culture, defining service reliability targets, or reducing on-call pain.

Reviews sqlx database code for compile-time query checking, connection pool management, migration patterns, and PostgreSQL-specific usage. Use when reviewing Rust code that uses sqlx, database queries, connection pools, or migrations. Covers offline mode, type mapping, and transaction patterns.

Reviews SQLAlchemy code for session management, relationships, N+1 queries, and migration patterns. Use when reviewing SQLAlchemy 2.0 code, checking session lifecycle, relationship() usage, or Alembic migrations.

Deep SQL performance workflow—symptom framing, execution plans, indexing strategy, query rewrite, locking/transaction behavior, statistics, partitioning, and verification. Use when queries time out, DB CPU spikes, or migrations change access patterns.

SQL 查询、数据获取智能体。覆盖 SQL 全链路能力：自然语言转生产级 SQL、慢查询诊断与执行计划分析、索引设计与优化、数仓建模、SQL 原理深度科普、查询结果可视化。支持 MySQL / PostgreSQL / Hive / Spark SQL / ClickHouse / BigQuery 多方言。触发场景：(1) 写 SQL / 生成查询，(2) SQL 慢/优化/调优，(3) 执行计划分析 EXPLAIN，(4) 索引设计，(5) 数仓建模 / 分层设计，(6) SQL 原理问题（事务/锁/MVCC/Join算法等），(7) 表结构设计 DDL，(8) SQL 报错诊断，(9) 任何"帮我写个查询"、"这个SQL为什么慢"、"怎么建索引"类请求，(10) 查询结果可视化 / 出图 / 图表 / 数据展示。

数学运算技能，支持算术、代数方程、函数求值、微积分与矩阵计算。用于用户提出“帮我算一下”“解方程”“求导/积分”“矩阵运算”等数学任务时，优先通过内置脚本稳定计算并返回结果。

Multi-agent development workflow with Sprint Contracts and independent QA evaluation. Use when building features, fixing complex bugs, or any task that involves spawning sub-agents to do work. Implements the Planner-Generator-Evaluator pattern (inspired by Anthropic's GAN-style harness design) to ensure quality through explicit completion criteria and independent testing. Triggers on development tasks, feature builds, bug fixes, code reviews, or when spawning coding agents.

Search files, apps, and metadata on macOS using Spotlight CLI tools (`mdfind`, `mdls`, `mdutil`) with a fallback script for cases where indexing is incomplete. Use when the task is to find documents, PDFs, apps, file paths, or metadata on a Mac, especially for prompts like "spotlight search", "find this file on mac", "search my computer", "find PDFs", "locate an app", or "check file metadata".
