gemini preset revision

Use this child for the named built-in gemini preset. geminiPreset in tui/internal/preset/preset.go:1332 uses Google's native gemini adapter, the stable gemini-3.8-flash default, GEMINI_API_KEY, web_search, skills, and a native vision capability. gemini-3-flash-preview was the previous preview default. It has no base_url or OpenAI-compatibility override.

Native inline image input is distinct from the explicit LingTai vision capability; both use the shipped Gemini provider rather than a fallback. The explicit LingTai vision capability is a separate tool path from native multimodality.

Template-specific settings

Read Google's official Gemini model guide and image understanding guide. For the actual account-served list, call the official Gemini API models.list endpoint, GET https://generativelanguage.googleapis.com/v1beta/models, or use the equivalent official SDK method; follow pagination and filter for models supporting the operation used by this adapter. This is a native provider catalog, not a gateway alias. Keep preview/stability and image-input facts separate, and do not infer a LingTai MCP from native multimodality.

TUI surfaces to revise

Start at geminiPreset in tui/internal/preset/preset.go. Gemini intentionally has no providerModels picker or modelHasVision entry in tui/internal/tui/preset_editor.go, so revise only the constructor's model, credential, and vision capability unless that design changes. If capability display changes, inspect the fixed mandatoryCapRow rendering; there is no Gemini base_url surface. Follow tui/CONTRACT.md for free-text providers.

Reviewed deterministic revision

Prepare an evidence-bound manifest and explicit input, then run lingtai-tui presets revise --manifest PATH --input PATH --mode dry-run|check|apply [--output-dir PATH]. Review the JSON plan, use dry-run/check before apply, and apply only to a new explicit output directory. revision.go validates hashes, route bindings, and evidence and preserves unowned bytes. This amendment revises the constructor default to gemini-3.8-flash; the model remains free text and is intentionally absent from providerModels and modelHasVision.

Maintenance: If the relevant TUI preset/page is revised, check whether this sub-skill also needs revision and, if so, include it in the same PR.

Operations

For save, endpoint/capability, availability, activation/refresh, or troubleshooting, use the five shared operation children under reference/operations/; this child owns Gemini preset facts.
