  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads baoyu-danger-gemini-web automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Gemini Web Client

Text/image generation via Gemini Web API. Supports reference images and multi-turn conversations.

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, request_user_input, clarify, ask_user, 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.

Script Directory

Important: All scripts are located in the scripts/ subdirectory of this skill.

Agent Execution Instructions:

  1. Determine this SKILL.md file's directory path as {baseDir}
  2. Script path = {baseDir}/scripts/<script-name>.ts
  3. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun
  4. Replace all {baseDir} and ${BUN_X} in this document with actual values

Script Reference:

ScriptPurpose
scripts/main.tsCLI entry point for text/image generation
scripts/gemini-webapi/*TypeScript port of gemini_webapi (GeminiClient, types, utils)

Consent Check (REQUIRED)

Before first use, verify user consent for reverse-engineered API usage.

Consent file locations:

  • macOS: ~/Library/Application Support/baoyu-skills/gemini-web/consent.json
  • Linux: ~/.local/share/baoyu-skills/gemini-web/consent.json
  • Windows: %APPDATA%\baoyu-skills\gemini-web\consent.json

Flow:

  1. Check if consent file exists with accepted: true and disclaimerVersion: "1.0"
  2. If valid consent exists → print warning with acceptedAt date, proceed
  3. If no consent → show disclaimer, ask user via AskUserQuestion:
    • "Yes, I accept" → create consent file with ISO timestamp, proceed
    • "No, I decline" → output decline message, stop
  4. Consent file format: {"version":1,"accepted":true,"acceptedAt":"<ISO>","disclaimerVersion":"1.0"}

Preferences (EXTEND.md)

Check EXTEND.md in priority order — the first one found wins:

Authentication

First run opens browser for Google auth. Cookies cached automatically.

When no explicit profile dir is set, cookie refresh may reuse an already-running local Chrome/Chromium debugging session tied to a standard user-data dir. Set --profile-dir or GEMINI_WEB_CHROME_PROFILE_DIR to force a dedicated profile and skip existing-session reuse. This is a best-effort CDP session reuse path, not the Chrome DevTools MCP prompt-based --autoConnect flow described in Chrome's official docs.

Supported browsers (auto-detected): Chrome, Chrome Canary/Beta, Chromium, Edge.

Force refresh: --login flag. Override browser: GEMINI_WEB_CHROME_PATH env var.

Environment Variables

VariableDescription
GEMINI_WEB_DATA_DIRData directory
GEMINI_WEB_COOKIE_PATHCookie file path
GEMINI_WEB_CHROME_PROFILE_DIRChrome profile directory
GEMINI_WEB_CHROME_PATHChrome executable path
HTTP_PROXY, HTTPS_PROXYProxy for Google access (set inline with command)

Sessions

Session files stored in data directory under sessions/<id>.json.

Contains: id, metadata (Gemini chat state), messages array, timestamps.

Extension Support

Custom configurations via EXTEND.md. See Preferences section for paths and supported options.

codex-pet

prime-skills/runcomfy-agent-skills

Codex Pet generator on RunComfy. Build a Codex-compatible Codex Pet spritesheet.webp + pet.json from a single reference image, drop it into ${CODEXHOME:-$HOME/.codex}/pets/ / and Codex picks it up as a custom Codex Pet next to the 8 built-ins. This skill produces the exact Codex Pet atlas Codex expects (1536x1872 PNG/WebP, 8 cols x 9 rows, 192x208 cells, 9 animation states — idle, running-right, running-left, waving, jumping, failed, waiting, running, review). Calls OpenAI GPT Image 2 edit ONCE via the local RunComfy CLI as runcomfy run openai/gpt-image-2/edit to produce a canonical Codex Pet pose, then assembles all 9 animation rows programmatically with ImageMagick micro-transforms — no Codex Pro, no $imagegen, no OPENAIAPIKEY required, only RUNCOMFYTOKEN. Triggers on "codex pet", "create codex pet", "make codex pet", "hatch codex pet", "/hatch image", "desktop pet codex", "codex pets", "spritesheet.webp", or any explicit ask to build a custom pet for OpenAI Codex.
