Individual skill

second-opinion-gemini

Get a second opinion from Google's Gemini Pro via the locally installed Gemini CLI (defaults to gemini-3.1-pro-preview; override with the CLAUDE_SECOND_OPINION_MODEL env var). This is the explicit / fallback engine — invoke ONLY when the user explicitly says "ask Gemini", "Gemini's take", "what does Gemini think", or "ask both" (run alongside the default engine and synthesize). Do NOT trigger on a generic "second opinion", "another perspective", or "cross-check this" — those route to the default `second-opinion` skill. Reserve this for when the user specifically wants Gemini, or as a fallback when the default engine is unavailable. Reports unavailability rather than falling back to a weaker model.

# Second Opinion — Gemini (explicit / fallback engine)

Get an independent second opinion from Google's Gemini Pro. This model has a completely different architecture and training from Claude, making it genuinely useful for catching blind spots, validating reasoning on edge cases, or surfacing trade-offs you might miss.

**This is NOT the default second-opinion engine.** Generic second-opinion requests route to the default `second-opinion` skill. Use this Gemini skill only when:
- The user explicitly asks for Gemini ("ask Gemini", "Gemini's take", "what does Gemini think").
- The user says "ask both" — run this *and* the default `second-opinion` skill, then synthesize all three views (yours + the default engine's + Gemini's).
- The default engine was reported unavailable and the user wants the alternate independent voice.

Gemini has full read access to the project — it can read files, grep code, and explore the codebase. Its project instructions (GEMINI.md) tell it to prime itself on the key docs before answering. You provide the specific question and any focused context; Gemini handles the rest.

## Model selection

Pinned to `gemini-3.1-pro-preview` by default for quality (smaller models give weaker second opinions; not worth the false confidence they create).
