gemini-proxy

gemini-proxy is a skill for Claude Code from freestyler-arb/imagine-gemini-for-claude-codex. It costs 120 tokens per session (1,457 once invoked), scanned A, original, MIT.

A prompt-polishing mode that sends the next set of substantial requests to Gemini, which rewrites them into clearer, more detailed instructions before the agent responds. Gemini improves the wording but does not replace the conversation or perform the task itself.

In plain words
What is it for?
It helps refine prompts during an agent session, including requests to enable or disable Gemini-based rewriting.
Why use it?
It helps turn brief or ambiguous requests into instructions with more useful context. The mode can be grounded in project rules, safety limits, and standing expectations.

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.

Security

Grade A, and why

gemini-proxy 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 2mo ago.

The scan reads SKILL.md. This mod also ships 4 executable files (hook/gemini_proxy_hook.py, proxy_route.py, proxy_state.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Overview

A prompt-polishing protocol. While active, each of your next N substantive prompts is first sent to Gemini — a senior prompt engineer — which rewrites the operator's message into a sharper, more detailed first-person version (still the operator's own message, not a standalone brief). The assistant then answers that improved message with the full chat context, project rules, and memory — Gemini only sharpens the wording, it does not replace the conversation. Trivial / config / meta prompts are skipped. Self-disables after N. Control layer only: it calls nothing but the counter and the gemini wrapper.

Ground it first (the step that makes this good, not generic)

A rewrite with no project context is mediocre. Copy the shipped template into the project and fill it with the project's canon, safety invariants/guardrails, and standing expectations (the habits you want on every task — keep a tracker, finish work to the plan, use the right skills, get an independent review on risky/money changes, goal-drift check). Then Gemini rewrites WITH your project in mind.

cp <skill>/prompt-rules.template.txt ./.gemini-proxy-rules.txt   # then edit: CANON / STANDING EXPECTATIONS / GUARDRAILS

Resolution order: $GEMINI_PROXY_RULES → ./.gemini-proxy-rules.txt → ./.claude/gemini-proxy-rules.txt → prompt-rules.template.txt. The richer this file, the sharper and safer every rewrite — it's the highest-leverage thing you do here.

When to route vs skip (the smart filter)

Decide BEFORE calling Gemini. Bias to ROUTE for real work; SKIP only clear noise. Skipped prompts never spend the counter, so N = N routed prompts.

ROUTE — counts as 1 of N SKIP — no Gemini, no counter
build / fix / refactor / audit / design / research greeting, thanks, yes/no, "status", "continue"
vague or large asks ("do all of this", "make it nice") config / setup / preferences about how we work or this protocol
anything that benefits from a sharper brief pure meta / diagnostic ("did you use Gemini?", "what did you mean?")

What this file has done since we first saw it

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.
