What is pi-ask-gemini?

A command that sends a user's question to Google's Gemini model and returns its answer alongside Claude's perspective. It can include relevant project files when the question concerns code.

Use it to ask Gemini for a second opinion on technical questions, code, or project decisions through the configured command-line tool.

It lets a coding session compare another model's answer without manually copying the question and context.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00011	$0.00738
Opus 5	$0.00005	$0.00369
Sonnet 5	$0.00002	$0.00148
Haiku 4.5	$0.00001	$0.00074

Measured 10d ago against content hash 1089e46c34ad, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

pi-ask-gemini scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ask Gemini

Forward the user's question to Gemini (via agy, the Antigravity CLI), get Google's perspective.

Execution

Bash invocation rules (v0.12.3+): Call call-codex.sh / call-gemini.sh in foreground synchronous mode with timeout: 600000 (Bash tool's 10-minute ceiling). Do not use &, do not set run_in_background: true, do not use nohup — Claude Code 2026-04+ has an auto-background child-lifecycle regression that silently kills the process (output file stays 0 bytes). Use run_in_background: true + BashOutput polling only as an exception when the call is genuinely expected to exceed 10 minutes.

1. Build the prompt

Use $ARGUMENTS as the prompt. If the question involves project code, read relevant files with the Read tool and append them.

2. Call Gemini

Wrap the question in the one-shot framing below (the framing prefix is fixed; $ARGUMENTS is the user's question verbatim):

CLAUDE_PRISM_TIMEOUT=300 CLAUDE_PRISM_CALLER=pi-ask-gemini ~/.claude/scripts/call-gemini.sh "You get exactly one turn: do not ask clarifying questions. If context is missing, state your assumptions and answer anyway. Lead with your answer, then reasoning. Be concise by default — expand only where the question demands depth.

Question:
$ARGUMENTS"

If code context is needed, pipe it via stdin (avoids ARG_MAX limits):

echo "Relevant code:
$(code content)" | CLAUDE_PRISM_TIMEOUT=300 CLAUDE_PRISM_CALLER=pi-ask-gemini ~/.claude/scripts/call-gemini.sh "You get exactly one turn: do not ask clarifying questions. If context is missing, state your assumptions and answer anyway. Lead with your answer, then reasoning. Be concise by default — expand only where the question demands depth.

Question:
$ARGUMENTS"

3. Handle failures

If Gemini fails (script exits non-zero or CLI not found):

Claude answers the question directly.
Include the specific failure reason from stderr (the script classifies errors as TIMEOUT, RATE_LIMIT, AUTH_ERROR, PERMISSION, NETWORK, EMPTY_OUTPUT, CLI_ERROR, or CLI_NOT_FOUND).
Note in output: "⚠️ Gemini unavailable ([reason]) — answering with Claude only. For multi-provider perspectives, try /pi-askall."

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
