baoyu-cover-image
Generates article cover images with 5 dimensions (type, palette, rendering, text, mood) combining 11 color palettes and 7 rendering styles. Supports cinematic (2.35:1), widescreen (16:9), and square (1:1) aspects. Use when user asks to "generate cover image", "create article cover", or "make cover".
Why this skill is useful
Adds a unique command-line tool for generating custom cover images based on article content and specified styles, which the AI wouldn't generate on its own.

What this skill does
Cover Image Generator Generate elegant cover images for articles with 5-dimensional customization. User Input Tools When this skill prompts the user, follow this tool-selection rule (priority order): 1. Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, requestuserinput, clarify, askuser, or any equivalent. 2. Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question. 3. Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order. Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes. Image Generation Tools When this skill needs to render an image, resolve the backend in this order: 1. Current-request override — if the user names a specific backend in the current message, use it. 2. Saved preference — if EXTEND.md sets preferredimagebackend to a backend available right now, use it. 3. Auto-select (when the preference is auto, unset, or the pinned backend isn't available): Codex (imagegen) — first, inspect your available-skills / tool inventory. If a skill named imagegen is listed, you are running inside Codex and MUST use it: invoke via the Skill tool with skill: "imagegen", passing the saved prompt file's content (plus output path and aspect ratio per Codex imagegen's own args). Codex imagegen is the official raster backend in that runtime and outranks any non-native skill (e.g., baoyu-image-gen) unless the user has explicitly pinned a different preferredimagebackend. Codex via codex exec (codex-imagegen) — if the current runtime exposes no native imagegen skill but the codex CLI is on PATH with an active codex login, route through baoyu-image-gen --provider codex-cli (preferred), or — if baoyu-image-gen is unavailable — invoke the bundled wrapper directly. …
