Guidance for writing effective prompts for Antigravity (agy) / Gemini 3 models.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Gemini 3 Prompting for agy Use this skill only to tighten a user's request into a better agy prompt before forwarding to `task`. ## Effective prompt structure 1. **State the goal clearly** — one sentence describing the desired end state 2. **Provide context** — relevant files, error messages, or constraints the agent should know 3. **Specify scope** — what agy should and should not touch 4. **State acceptance criteria** — how to know when the task is done ## Do - Be specific about files, functions, or components involved - Include error messages verbatim if debugging - Mention the tech stack (React, Python, etc.) if not obvious from the repo - Ask for a specific output format when the result needs to be consumed downstream ## Don't - Don't ask agy to "look at everything" — scope it to the relevant area - Don't include Claude-side analysis in the prompt — forward the raw task - Don't add commentary or padding — agy works best with concise, direct prompts - Don't include `--background`, `--continue`, or `--fresh` flags in the prompt text ## Prompt antipatterns | Antipattern | Better | |---|---| …

How to install
mdr add vit129/agy-plugin-cc/gemini-3-prompting@sha256:8afb18cc270cf279The line at the top of this page pins the label git:20260527.8569a2e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
