Creates, explains, reviews, and converts human-readable text descriptions of circuits using CDL (Circuit Description Language). Use when the user wants to express circuit requirements or schematic information as CDL, decompose a circuit description into CDL blocks, review CDL syntax and completeness, convert CDL into a logical netlist, or generate the synchronized CSV BOM that mirrors the CDL component declarations. Also trigger on "describe this circuit", "write CDL", "convert CDL to netlist", "review my CDL", "check my circuit description", or when a schematic image needs a component-level text representation. This skill teaches CDL syntax and workflow only; it does not provide circuit design templates or prescribe how to implement specific modules. Do NOT trigger for parsing .enet files, product-level schematic design review, PCB layout, SPICE simulation, procurement, or EDA library mapping tasks.
Search the JLC/LCSC/SZLCSC/JLCPCB/EasyEDA component catalog with a mandatory two-stage workflow: first filter broad requirements into candidate parts, then fetch detailed facts and ENET-compatible fields only for one explicit LCSC number or exact MPN. Use when Codex needs 嘉立创/LCSC part numbers, datasheet PDF links, product links, EasyEDA footprint/symbol metadata, or structured component facts for later BOM/ENET work. Do not use this skill to modify .enet files or validate a circuit design.
Generate or update a durable project memory file for the current repository or workspace. Use when the user asks Codex to create project memory, summarize a codebase for future agents, capture repository conventions, write a memory file under ~/.codex/project-memory, refresh an existing project notes file, or preserve important context across projects.
Maintain current project documentation from useful conversation context. Use when the user asks Codex to write newly discovered facts, decisions, commands, conventions, troubleshooting notes, or agent instructions into README, AGENTS.md, docs/, ADRs, runbooks, or project memory; when the user says to preserve, document, remember in docs, update docs from this discussion, or keep project documentation in sync with what was just learned.
Operate remote Linux/Unix hosts over SSH from Codex. Use when the user asks to connect to a server, run remote shell commands, keep a persistent SSH shell, upload or download files with SFTP, inspect services or processes, deploy code/configuration, or manage a remote machine through SSH key authentication.
解析嘉立创EDA专业版（JLCEDA Pro / EasyEDA Pro）导出的 .enet 网表文件，提取元件列表、网络连接、BOM、电源分析等信息，并生成适合 AI 理解的结构化摘要。当用户上传或提及 .enet 文件、嘉立创网表、立创EDA网表、或询问 PCB 网络连接、元件清单时，必须使用此 skill。即使用户只说"帮我看一下这个网表"，也应触发此 skill。
Use when the user wants to download a KEATS course from a course URL plus a browser cookie file or Playwright auth-state JSON, organize materials into section-based folders such as Week or Topic, or avoid manually copying KEATS/Moodle cookies.
Generate, inspect, validate, edit, and geometry-check Project Graph `.prg` files from natural-language requirements or reference diagrams. Use when Codex needs to create a new `.prg`, modify an existing `.prg`, inspect a `.prg` archive, validate required nodes/edges/sections, enforce no-overlap layout rules, or route edges around blocks.
