Gemini Web Reverse-Engineered Client

What it does

When your agent uses it

• Generating an image or text response through Gemini's web interface
• Providing a reference image as vision input for a Gemini generation
• Continuing a multi-turn conversation with the Gemini web backend

Example prompts

• “Generate an image of a mountain cabin at sunset with Gemini.”
• “Use this reference photo to generate a similar image with Gemini.”
• “Continue this Gemini conversation and ask it to adjust the lighting.”

Requirements

• Bun or npx to run the bundled TypeScript client
• User consent recorded in a local disclaimer file

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

1. 1Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or…
2. 2Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each…
3. 3Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question…

What it can do on your machine

Read from SKILL.md and the folder at commit 1567581. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 15 files in scripts/ (TypeScript, from the files we listed), which the agent can run.

  Shell commands in SKILL.md call:

  • npx

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gemini Web Reverse-Engineered Client loads about 1.6k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 548 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~95

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

Generates images and text via reverse-engineered Gemini Web API. Supports text generation, image generation from prompts, reference images for vision input, and multi-turn conversations. Use when other skills need image generation backend, or when user requests "generate image with Gemini", "Gemini text generation", or needs vision-capable AI generation.
