skills

Control and inspect a real local Chromium-family browser through the bro MCP server and WebExtension. Use when Codex needs logged-in browser access, current tab inspection, page text or link extraction, multi-URL background extraction, click/fill/read flows, or browser console and network diagnostics. Do not use for ordinary web lookup when generic web browsing is sufficient.

Use when Codex needs to work with Mimestream mail on this Mac: investigate local mail, search receipts or support threads, identify actual recipients from sent mail, read selected messages, draft or reply in Mimestream, visually verify compose windows, or perform explicit mailbox actions. Prefer Gmail API skills for server-authoritative send/delivery/label/thread state that does not depend on Mimestream.

Use when Codex needs to control or inspect the user's logged-in Helium browser through the locally installed OpenBrowserMCP extension. Trigger for requests about OpenBrowserMCP, Helium tabs, reading current browser tabs, browser MCP, openbrowsermcp, webpage interaction, or testing this local browser stack.

Build and run evidence-based learning workflows. Use when Codex needs to create or continue a study workspace, collect and convert learning materials, design goals, teach from sources, quiz the user, score answers, track progress, maintain an error log, or run spaced review for subjects such as courses, books, technical topics, exams, or career prep.

Use when Codex needs to access Monarch Money through the local mon CLI for auth status, accounts, transactions, custom GraphQL queries, or diagnostics while keeping local tokens private.

Extract text, Markdown, tables, formulas, and structured content from PDFs, scanned documents, screenshots, and images using the best available local or cloud OCR route. Use when Codex needs OCR, PDF text-layer extraction, MinerU local or official API parsing, VLM document parsing, table/formula extraction, scanned PDF handling, or when deciding whether a PDF should be read directly, OCRed, parsed by MinerU, or uploaded to a cloud API.

Use when the user wants to read, search, inspect, back up, export, or troubleshoot local macOS Telegram chat history with tg. Keep the user's chat data local and guide them through the shortest working tg command flow.

Use when Codex needs to work with 1Password or the `op` CLI: reading a specific secret reference, injecting API keys or credentials into local commands, using `op run` or `op inject`, checking 1Password CLI auth state, handling `API_CREDENTIAL` items, creating or updating 1Password items, or deciding how to keep secrets out of code, logs, shell history, issues, PRs, and final responses.

Inspect, create, and verify events in macOS Calendar.app with osascript-backed local automation. Use when Codex needs to audit local Apple Calendar sources/defaults, understand Calendar.sqlitedb cache state, or add an event directly to a specific Apple Calendar calendar on the current Mac. Prefer Google Calendar skills for durable calendar writes unless the user explicitly asks for Apple Calendar.

Govern and maintain the user's personal calendar system across Google Calendar, Apple Calendar.app, school/legacy accounts, and automation. Use when Codex needs to audit calendar state, choose the correct write target, create or verify calendar events, clean up cluttered calendar lists, rename or hide calendars, migrate away from school/Apple/iCloud/legacy sources, prevent non-authoritative accounts from owning personal events, or reason about Google Calendar vs macOS Calendar.app behavior.

Use when Codex needs to work with Canvas LMS / Instructure through the Canvas API: listing courses, finding course IDs, reading syllabi, assignments, modules, pages, files, submissions, grades, rubrics, due dates, or calculating current/final/maximum course grades. Also use when a user asks to submit Canvas assignments or download Canvas course materials, while keeping Canvas tokens in macOS Keychain or environment variables.

Use when a user asks to debug or fix failing GitHub PR checks that run in GitHub Actions. Use GitHub MCP tools for PR metadata and patch context, and use `gh` for Actions check and log inspection before implementing any approved fix.

Inspect and address GitHub pull request review state, including latest PR comments, review submissions, unresolved inline threads, actionable review feedback, and post-fix thread resolution. Use when Codex needs to check "latest PR comments", summarize or implement requested PR changes, inspect the current branch PR, or resolve review threads after fixes are pushed.

Triage and orient GitHub repository, pull request, and issue work through local GitHub MCP tools and the `gh` CLI. Use when the user asks for general GitHub help, wants PR or issue summaries, or needs repository context before choosing a more specific GitHub workflow.

Google Calendar: Create a new event.

Google Calendar: Manage calendars and events.

Query and read past coding-agent session/conversation history, across both opencode and codex. Use when the user wants to recall something discussed in a previous session, search past conversations by keyword, review context from old sessions, or continue prior work. Triggers include "查一下之前的聊天记录", "还记得上次那个...", "look up a past session", "what did we talk about...", or any request to recall historical context.

Create, verify, and use local Telegram MTProto user sessions with Telethon, including fast date-bounded chat history sync into local SQLite/FTS and local history queries. Use when Codex needs to log in to Telegram with a phone account, validate an existing .session file, read Telegram channel/group/chat history, search or inspect Telegram chats through the user API, or recover from broken/unauthorized sessions while keeping Telegram app credentials in macOS Keychain.

Publish local changes to GitHub by confirming scope, committing intentionally, pushing the branch, and opening a draft PR through GitHub MCP tools, with `gh` used only as a fallback where connector coverage is insufficient.

Read and search local macOS Messages.app iMessage/SMS history directly through the chat.db SQLite database. Use when the user wants to read, search, or analyze local iPhone messages, SMS, iMessage conversations, or message attachments on this Mac.

Use when Codex is writing, editing, reviewing, or designing Rust systems code, Rust CLIs, async runtimes, FFI wrappers, unsafe abstractions, security-sensitive crates, local-first developer tools, or code style guidance for this user's Rust projects. Also use when a non-Rust engineering task would benefit from the same discipline: small APIs, explicit invariants, reviewable failure behavior, and conservative dependency/security choices.

Build an evidence-driven review plan for a course exam or final. Use when the user wants to prepare for a new course exam by collecting recordings/transcripts, identifying the official exam scope, mining homework/practice exams/past exams/forums, and turning the result into a concrete study plan or Things 3 project.

Gmail: Send, read, and manage email.

Use when Codex should turn a local pain point, repeated workflow, API wrapper, or automation idea into a small shippable AI-native CLI product, especially a Rust CLI with GitHub repository, CI, release automation, Homebrew formula, install command, README, architecture docs, and optional Codex skill integration. Trigger for requests like "make this into a tool", "create a ~/dev project like tg/cx/mon", "ship a CLI product", "wrap this API for agents", "add Homebrew/GitHub release", or "abstract this workflow into a reusable developer product".

Use when Codex needs to operate the local Codex multi-slot workflow with cx, including selecting the best slot, checking usage, creating or logging into slots, or validating slot state.

Shared authentication, security, and command conventions for locally generated Google Workspace gws skills.

Extract real downloadable mp4 URLs from Panopto and similar HLS lecture players, then batch-download all lectures with manifests and retry logic. Use when users ask to download many class videos from a logged-in Panopto folder, to automate IDM-style URL discovery, or to derive fragmented.mp4 links from Viewer pages.

Manage Things 3 on macOS through the official Things URL scheme. Use when asked to add, batch-import, update, show, search, or programmatically locate existing open to-dos/projects in Things, especially when an auth token should be injected from an env file.
