Cross-vendor audit rests on one non-Anthropic vendor (Forge/OpenAI) — GeminiResearcher/GrokResearcher run on model: opus; add a real Google path via Antigravity CLI (agy) + an AUDIT mode

[xmasyx]

Summary

The cross-vendor verification pass at E4/E5 exists to escape blind spots shared across the executor's and reviewer's training distribution. Today only Forge (OpenAI GPT‑5.6 Sol, via codex exec) genuinely leaves the Anthropic family. The other "cross-vendor" agents — GeminiResearcher and GrokResearcher — name a non‑Anthropic vendor but set model: opus and carry no vendor-specific invocation path, so at runtime they execute on Claude. The cross-vendor audit therefore rests on a single non‑Anthropic vendor.

Proposal: adopt Google's Antigravity CLI (agy) — the first-party successor to Gemini CLI — as a genuine Gemini backend (the Google analog to the codex CLI Forge already uses), and give GeminiResearcher an AUDIT mode parallel to Forge's, so E4/E5 gains a real Google-family auditor.

Evidence (upstream)

• agents/GeminiResearcher.md frontmatter is model: opus; agents/GeminiResearcherContext.md's methodology is prompt-only ("multi-perspective research", WebSearch/WebFetch) with no Gemini CLI or API call. GrokResearcher has the same shape.
• The only GEMINI_API_KEY reference in the tree is Tools/InstallEngine.ts (install-time key detection/storage), not a runtime research/audit path. No agent shells a real Google model.
• Contrast: agents/Forge.md genuinely shells codex exec (OpenAI) and already exposes BUILD + AUDIT modes; USER/ALGOPREFS.md wires "Cross-vendor audit (Forge) on high-stakes verification: Yes (default)".

Quick reproduction:

grep -H '^model:' agents/GeminiResearcher.md agents/GrokResearcher.md   # -> model: opus
grep -rEl 'agy|gemini-cli|generativelanguage\.googleapis' agents/       # -> no runtime Gemini path

Why it matters

Two independent reasons:

1. Distributional diversity. The cross-vendor audit's whole value is that an auditor from the same model family shares the exact blind spots the pass is meant to catch. With Forge as the only genuine non‑Anthropic auditor, an OpenAI-shared blind spot gets no independent second opinion, and a "Gemini"/"Grok" review is in fact Claude re‑auditing Claude — diversity of persona, not of distribution. A genuine Google-family runtime closes that gap and makes the "cross-vendor" label true.

2. Access / availability. Just as important: today the cross-vendor audit is reachable only if you have an OpenAI (codex) account, because Forge is the sole genuine non‑Anthropic path. A user who has Google/Gemini access but not OpenAI or xAI can't run a cross-vendor audit at all — the feature is effectively gated behind one specific vendor. Adding an agy-backed Gemini auditor lets people use whichever second vendor they already have, widening who can benefit from cross-vendor verification instead of locking it to a single provider. This matters most for the users who don't happen to hold an OpenAI subscription.

Honest caveat — a Gemini/agy researcher does not replace Grok's X access

For the researcher role specifically (not the read-only auditor), I want to be upfront that Grok has a genuinely distinctive capability Gemini lacks: native, real-time access to X — it reads individual posts as they're posted through a direct pipe to X, which is uniquely valuable for breaking-news and live-sentiment research. Gemini via agy does not have that; like other web-search models it crawls the indexed web and can't read live X posts. What it does bring is general online search (Google Search grounding), and it's strong at broad web research.

So an agy-backed Gemini researcher is a complement to a Grok researcher, not a substitute for X-specific work. But it still moves the needle on the access point above: for someone who has Google and not xAI, it provides genuine non‑Anthropic, online-search-capable research where they'd otherwise have none — which is better than a "GrokResearcher" that, today, actually runs on model: opus and reaches neither X nor a non‑Anthropic model.

Suggested solution

1. Gemini backend via Antigravity CLI (agy). Mirror how Forge uses codex exec: run agy headless (-p / --print) with --sandbox for a read-only terminal, no --add-dir (pass the audit payload inline in the prompt), and pin the model to a Gemini (e.g. Gemini 3.1 Pro). agy is a single Go binary, first-party Google, and the announced successor to Gemini CLI — a clean parallel to the codex dependency Forge already carries. (Antigravity CLI overview + migration notice linked below.)

2. AUDIT mode on GeminiResearcher, exactly like Forge's second mode: a read-only pass at E4/E5 returning schema-enforced JSON findings, prompted to surface blind spots shared across the Anthropic executor/reviewer and the OpenAI auditor — i.e. what a Google model notices that neither of the others does. Keep the invariant "never audits work it built".

3. (Optional, small) fix the labeling. A model: opus agent called GeminiResearcher is misleading as-is; either back it with agy per (1) or document it as persona-diverse rather than vendor-diverse.

Reference design (in local use)

A read-only Gemini auditor of this shape is already runnable in practice. Notes that may save design time:

• Read-only is engineered, not inherited. agy is an actuator (it will try grep/pwd), so isolate it: throwaway temp CWD, no --add-dir, --sandbox, the whole audit payload inlined in the prompt, and a prompt that forbids tool use and demands JSON only.
• Auditor prompt targets shared-distribution failure modes explicitly: format conventions read as "correct", shared API-contract misreadings, completeness-claim bias ("good enough"), overconfidence on ambiguous criteria — framed as "you run on Google Gemini; the executor and reviewer are Anthropic and the other auditor is OpenAI; find what THEY share and miss."
• Model pin as an invariant: the audit model must be a Gemini — agy also exposes Claude Opus/Sonnet, and picking those would be same-family self-review, the bias the audit exists to kill.
• Findings appended as JSON lines for later inspection.

Happy to contribute the full tool as a starting point if a Google-family auditor is wanted.

One direction worth considering for this: provide a way to select other models for the cross-vendor audit, including local Ollama models, not just codex.

Tested this directly rather than just proposing it — a standalone script that feeds a real file plus an audit prompt (adapted from CrossVendorAudit.ts's own AUDIT_PROMPT) directly to a local Ollama model over its HTTP API, parses back a structured JSON verdict. Ran against a real ~230-line Python file.

Environment: AMD Ryzen AI 9 HX PRO 370 (24 threads), 86GB RAM, Ubuntu 24.04.4 LTS, Ollama 0.17.7, Bun 1.3.11, LifeOS 7.1.1. CPU-only inference (no GPU/NPU acceleration configured for Ollama).

Results:

• qwen2.5:14b-instruct-q4_K_M — completed in 285s. Mechanically sound (real model, real file, valid JSON verdict), but the findings were shallow — mostly restatements of what the code does rather than sharp blind-spot catches.
• qwen2.5:32b — given a full 20-minute allowance, did not complete. Confirmed limitation with a real test, not a guess. Plenty of RAM headroom throughout (only ~20GB in use of 86GB) — this is a compute-throughput limit, not a memory one.

Caveat: local models via the raw API have no tool-calling access, so the file(s) need to be pre-fed into the prompt rather than read agentically the way codex does — fine for a single file or small diff, not a drop-in for larger changes.

Net: workable as an added option for people who want a local/free path, with a real speed-vs-depth tradeoff on CPU-only hardware. Happy to share the script if useful.

Implemented — the audit lane now has a genuine Google leg. What landed in source:

• LIFEOS/TOOLS/GeminiAudit.ts — mirrors Forge's audit shape: read-only by construction (throwaway temp HOME + CWD, no extensions/MCP, payload inline, prompt forbids tools), JSON-only findings out, fail-loud unavailable verdict when the binary or key is missing (never a silent fallback to Claude). Your reference-design notes shaped it directly.
• Model pin as an invariant, per your warning: the tool refuses any non-Gemini model name.
• Binary: prefers agy when on PATH, falls back to gemini (gemini-cli) — verified end-to-end locally on gemini-3.1-pro-preview with a planted-defect audit that it caught.
• GeminiResearcher now has the AUDIT mode (MODE: audit spawn convention, same as Forge) plus your labeling fix: research mode is now documented as persona-diverse, not vendor-diverse.

Your access argument (cross-vendor audit shouldn't be gated on holding an OpenAI account) was the decisive one. Honest caveat accepted on Grok/X — this is a complement, not a substitute. Ships in the next release.

[danielmiessler]

Correction to the close above: on maintainer review, this was reversed before shipping. The decision is to keep the trusted vendor set for reasoning and audit lanes closed at Anthropic + OpenAI — adding a new model vendor to the audit path is a trust decision, not a capability gap, and the call is not to expand it. The GeminiAudit implementation was removed from source the same day it was built and never reached a release.

Your analysis was and remains technically correct on every point — the vendor-diversity gap is real, the labeling observation stands, and your reference-design notes were solid engineering. The issue stays closed, now as a decline on trust-boundary grounds rather than as shipped. Thanks for the depth of the writeup regardless — it made the decision a clear one instead of a vague one.

I perfectly understand. thanks to everyone who is working to make this amazing project every-release better and questioning others chain of thoughts.
Can I ask @danielmiessler the trust issue with Gemini? Just curious since I implemented it into the LifeOS I'm using

[danielmiessler]

It's not so much a trust issue, more so a simplicity of system, and I don't think they're adding anything that we're not getting from other parts of the system. I think if you are getting something from it, then that's not a problem. The only thing we're using it for is Nano Banana Pro.
