agy-prompting

Prompting agy (Gemini 3.x via Antigravity CLI)

Use this skill ONLY inside the antigravity:agy-rescue subagent when shaping the text you pass to agy --print. Do not use it to do independent reasoning, file inspection, or research yourself.

What agy is good at

• Native web search with citation grounding (real URLs, not hallucinated).
• Long-context reasoning over multiple sources.
• Following structured-output instructions (markdown tables, JSON, frontmatter).
• Tool calling for code generation and file edits when run with --dangerously-skip-permissions.

What agy is worse at than Claude

• Following complex multi-turn workflow rules. Keep the prompt single-shot and self-contained.
• Inferring implicit context — if a constraint matters, write it down.
• Localized linguistic nuance — explicitly ask for the target dialect ("Spanish (Argentina)", "Brazilian Portuguese", etc.) when the output language matters.

Prompt shape that works

<TASK in one sentence>.

Rules:
- <constraint 1>
- <constraint 2>
- ...

Output format:
<exact markdown / json schema you want>

<DATA / TOPIC>:
<the actual content>

Keep the rules to <= 8 bullets. More than that and Gemini starts dropping the tail.

Things to ALWAYS include

• Output language when relevant.
• Whether citations are required and the citation format ([N] style works best).
• The exact output structure with markdown headers.
• An anti-hallucination clause ("if you could not find a solid source, say so explicitly" / "mark weak claims as [WEAK EVIDENCE]").

Things to AVOID

• Multi-step "first do X, then do Y, then call me back" instructions. agy in --print mode is single-shot; chain steps from the caller side instead.
• Demanding more than ~20 sources unless the user asked for it — quality drops fast past that.
• Free-form "be creative" — for research, structure is what makes the output usable.
• Mixing rescue work (code edits) and research (web search) in the same call. Pick one.

Routing flags reminder

These are CALLER-SIDE controls, never include them in the agy prompt text:

• --print — non-interactive
• --dangerously-skip-permissions — auto-approve tool use
• --print-timeout 20m0s — high-intensity research needs long timeouts
• --continue — resume the most recent agy conversation
• --conversation <id> — resume a specific past conversation

--model is version-dependent (corrected v0.6.1): early agy 1.0.0/1.0.1 reject it with flags provided but not defined: -model, but agy 1.0.5+ accepts --model "<name>" (e.g. --model "Gemini 3.1 Pro (High)", community-confirmed on issue #76). Since the installed version isn't known at call time, this plugin defaults to NOT passing --model (cross-version-safe — agy uses its configured default). Pass it only when the caller explicitly asked for a model AND agy --version is ≥ 1.0.5. Either way, --model is a CALLER-SIDE flag — never put it in the prompt text.

When in doubt

Default to the templates baked into agy-rescue.md for research mode. Only deviate when the user explicitly asks for a different shape.
