+//! Provider-agnostic conversation-history sanitization.
+//!
+//! Some providers (notably Google Gemini) reject conversation histories whose
+//! first non-system turn is anything other than a `user` turn. ZeroClaw can
+//! produce such histories when context trimming, session restoration, or
+//! native-tool-call serialization leaves an `assistant` turn (often carrying
+//! `tool_calls`) at the head of the message list.
+//!
+//! Permissive providers (Anthropic, GLM) silently accept the malformed shape;
+//! strict providers return HTTP 400. See issue #6302 for the full repro.
+//!
+//! This module enforces the universal invariant: the first non-system message
+//! must be a `user` turn. Any leading `assistant` / `tool` turns that precede
+//! the first `user` turn are dropped, since without their corresponding
+//! `user` predecessor they are not interpretable by any provider.
+//!
+//! Tool-call/tool-response *pairing* (orphan `tool` messages without a matching
+//! `assistant.tool_calls`, empty `tool_calls: []` arrays, etc.) is tracked
+//! separately in #6298 and is intentionally out of scope here.

+//! Gemini image generation/edit tool routed via LiteLLM.
+//!
+//! Mirrors the `nano-banana-pro` skill: calls the LiteLLM `/chat/completions`
+//! endpoint with `modalities: ["image","text"]` against models like
+//! `gemini-api-image-banana2` (Gemini 3 Pro Image). Decodes the returned
+//! base64 image, saves it under `{workspace}/images/`, and returns a
+//! ready-to-use `[IMAGE:...]` marker in the tool output so channels that
+//! parse markers (Telegram, Matrix, …) deliver the file.
+//!
+//! Credentials are resolved in this order:
+//!   1. `LITELLM_BASE_URL` / `LITELLM_API_KEY` env vars
+//!   2. `[providers.models.litellm]` from `~/.zeroclaw/config.toml`,
+//!      decrypting `enc2:` values via the `SecretStore`.
