Remove backgrounds from images using each::sense AI. Create transparent PNGs, replace backgrounds with solid colors or scenes, and handle complex edges like hair with precision.
Multi-agent coordination discipline: one-message-then-wait (send complete context, wait for reply before sending again), idle notifications are heartbeats (no action unless extended + blocking + user asked), no polling loops (event-driven only), never fabricate agent responses (wait for real system events), sequential agent spawning (acknowledge between each), and proper shutdown protocol (request, wait, respect rejection). Activate when orchestrating multiple agents, managing agent teams, coordinating handoffs between agents, spawning subagents, or building multi-agent workflows. Triggers on: "coordinate agents", "spawn multiple agents", "manage agent team", "agent keeps sending messages", "polling loop", "agent idle", "shut down agent", "multi-agent workflow", "agent handoff", "coordinate parallel work", "stop bothering the other agent". Also relevant when an agent is fabricating responses, sending follow-up messages before replies arrive, or reacting to idle notifications unnecessarily.
Codified expertise for demand forecasting, safety stock optimisation, replenishment planning, and promotional lift estimation at multi-location retailers.
Use when constructing Nostr events from natural language descriptions, building kind-specific tag structures, implementing NIP-10 threading for kind:1 replies, creating NIP-22 comments on non-note content, or generating correct event JSON with proper e/p/a tag markers and serialization format.
Orchestrate large-scale TYPO3 code changes across multiple files in parallel.

Decomposes work into independent units, executes them, and verifies with tests. Use when working with batch, migrate, bulk, mass refactor, convert all, upgrade all, rename across, find and replace, parallel, codemod, TYPO3 migration.
Tools, patterns, and utilities for creating music with code. Output as a .mp3 file with realistic instrument sounds. Write custom compositions to bring creativity to life through music. This skill should be used whenever the user asks for music to be created. Never use this skill for replicating songs, beats, riffs, or other sensitive works. The skill is not suitable for vocal/lyrical music, audio mixing/mastering (reverb, EQ, compression), real-time MIDI playback, or professional studio recording quality.
Access and operate Gmail directly from scripts. Supports multiple accounts (link, list, unlink). Read inbox, search emails, read threads, reply with HTML/attachments/CC/BCC, send emails, manage labels, and manage drafts. On first use, runs an OAuth2 auth flow. Use when the user wants to read, search, reply, send, label, draft emails, or manage multiple Gmail accounts.
This skill should be used when the user asks to "edit an image", "modify a photo", "inpaint", "outpaint", "extend an image", "replace object in image", "add element to image", "resize image for social media", "crop image", "adapt image for Twitter", "convert image to OG format", or needs AI-powered image editing with masks.
Help create and optimize blog posts, articles, and polished writing with rigorous structure, reader expectation management, and SCQA methodology. This skill contains a specialized writing framework (reader personas, concept introduction protocol, diagnostic checklists, Pyramid Principle structure) that cannot be replicated without loading it. You must use this skill in any of these scenarios: (1) writing a blog post or article from notes/materials, (2) reviewing, diagnosing, or optimizing any draft or article for structure, clarity, and readability, (3) polishing or refining notes into publishable form, (4) giving feedback on writing structure, flow, or reader experience, (5) creating outlines for articles. Trigger on keywords: "博客", "文章", "发布", "blog", "写作", "初稿", "打磨", "诊断", "优化文章", "结构", "大纲", "投稿", "公众号", "读者". Also trigger when the user shares a markdown file and asks to improve it, or asks if something "reads well" or "makes sense to readers".
Web content fetching and URL retrieval via curl and WebFetch — replaces the Fetch MCP server (fetch_html, fetch_json, fetch_markdown, fetch_txt). Use this skill when a specific URL is provided and the user wants its content. Covers HTTP GET/POST, JSON API consumption with jq, HTML retrieval, markdown conversion, plain text extraction, authenticated requests, redirects, cookies, and timeouts. Trigger phrases: "fetch this URL", "get the page content", "download HTML", "call this API", "curl this endpoint", "grab the JSON", "fetch markdown from", "retrieve web content", "hit this endpoint", "scrape this page", "read this URL", "pull data from API", "make an HTTP request", "extract page content", "get article text". NOT for web searches without a URL — use tavily for that.
DEPRECATED: Use the model's native extended thinking instead. Structured, reflective problem-solving through sequential chain-of-thought reasoning that replaced the Sequential Thinking MCP server.
Keep Codex skills aligned with durable feedback by distilling comments, corrections, and repeated guidance into the narrowest existing skill. Use on every turn, and especially when feedback reveals a reusable rule, a repeated miss, or a better abstraction that should replace a task-specific example.
