## Image Resources
Image files are interpreted the same way: a vision model writes a caption card that links back to the original image.
Text and image resources share the same agent-wrapper and note-writing tools. Image inputs add a native AgentScope
image block alongside the interpretation instructions; the agent writes a caption card linked to the original image.
The card body starts with an `![[resource/...]]` embed link and the frontmatter carries `kind: image` and `media_type`,
so text search reaches image content through the caption.
The vision model is the `vision` instance of `as_llm` when configured, and otherwise falls back to the `default`
instance — a multimodal default model needs no extra configuration. Images wider or taller than 2048px are downscaled,
Image processing is enabled by default (`include_images=true`) and requires an AgentScope wrapper bound to a compatible
model and formatter. Configure the model through `components.agent_wrapper.<name>.as_llm`, selecting the wrapper with
`agent_wrapper` on the resource Step. The former image-Step `as_llm` override and automatic `as_llm.vision` selection
are replaced by that binding. There is no separate caption model, schema-extraction call, or text-only retry after an
agent failure. An agent workflow can make multiple model requests while using its tools.
Each image interpretation starts a new session. Use the returned `agent_session_id` to find its processing record;
reprocessing the same image still updates the original card. The body should contain the image embed followed by a
description or transcription under `## Caption`, not an empty caption or a JSON response. Leave `status` to later
processing steps and keep its existing value when updating the card.
Customize image instructions with `prompt_dict.resource_instructions` (`resource_instructions_zh` for Chinese).
Rename existing `user_message` / `user_message_zh` settings accordingly.
Shared create/update templates insert these instructions at `{resource_instructions}`; older templates
without the placeholder receive them at the end.
Set `include_images=false` on an `auto_resource` call or as a Job default to skip **all** image events, including
deletions. Call-time values override Job defaults; when neither is set, image processing is enabled. For the watcher, use
`jobs.resource_watch_loop.include_images=false`; for manual calls, use `jobs.auto_resource.include_images=false`.
The image processor reports each skip in the existing result and warning log; text processing is unchanged. Existing
image cards are left untouched, even if their source image is deleted. Re-enabling images does not replay skipped
events; explicitly submit the affected paths to `auto_resource` when compensation is needed. The wrapper's configured
image-count limit is respected and must allow at least one image per resource call; it is not increased automatically.
Configure the wrapper when starting the persistent service. For example, to allow one image per agent context:
```bash
reme start components.agent_wrapper.default.context_config.max_image_num=1
```
The watcher processes resource changes automatically. To explicitly reprocess an existing `resource/photo.png`, run
the client in another terminal using the same workspace:
```bash
reme auto_resource include_images=true changes='[{"path":"resource/photo.png","change":"modified"}]'
```
Images wider or taller than 2048px are downscaled,
and provider-unfriendly formats are re-encoded, in memory for the request only; the original file under
`resource/` is never modified. Before a full decode, image dimensions are checked against a default limit of 40,000,000
pixels; images over the limit and Pillow decompression-bomb warnings fail only that resource. EXIF orientation is
applied to the in-memory request copy before resizing or conversion. Oversized JPEGs first use decoder-level
downsampling, followed by a final thumbnail pass when needed. The VLM request MIME and the card's frontmatter
`media_type` use the format Pillow detects from the image bytes, rather than trusting the filename extension. When an
image changes, its card is rewritten in place; when the image is deleted, the card is removed with it.
image changes, its card is updated in place; when the image is deleted, the card is removed with it, provided image
processing is enabled.
Image preprocessing uses Pillow from the `core` extra. HEIC resources additionally require the optional
`image-heif` extra: `pip install "reme-ai[image-heif]"`. Other supported image formats do not load or require the HEIF

```
When a resource changes, Auto Resource finds and updates the corresponding card through an exact `source_resource`
match. When a resource is deleted, only the explicitly linked daily note is removed. A same-stem note without that
match. When an enabled resource is deleted, only the explicitly linked daily note is removed. A same-stem note without that
provenance marker is treated as user-owned and left untouched; new resource cards use a collision-free path instead.
A failed call may still have changed a card; `modified` records whether the file changed. If the agent writes the card
and then fails or is cancelled, the written content stays on disk. ReMe tries to complete metadata and update the day's
index for the card linked through `source_resource`, while preserving the original error or cancellation. A failed
image-note format check also leaves the written content in place. Failed calls are not retried automatically.
## Daily Index
Resource cards enter the same daily memory layer as Auto Memory cards. The day's `YYYY-MM-DD.md` page acts as an index

## 图像资源
图像文件的解读方式相同：视觉模型写入一张 caption 卡片并链接原图。卡片正文以 `![[resource/...]]` 嵌入链接开头，frontmatter 携带 `kind: image` 与 `media_type`，文本检索因此可以通过 caption 命中图像内容。
文本和图像共用 agent-wrapper 与笔记写入工具；图片输入只是在理解提示词旁加入原生 AgentScope 图像块。
Agent 写入一张 caption 卡片并链接原图。卡片正文以 `![[resource/...]]` 嵌入链接开头，frontmatter 携带
`kind: image` 与 `media_type`，文本检索因此可以通过 caption 命中图像内容。
视觉模型优先使用配置中的 `as_llm` `vision` 实例，未配置时回退到 `default` 实例——默认模型具备视觉能力时无需额外配置。宽或高超过 2048px 的图像会降采样，格式不被模型接受的图像会转码；这些处理只发生在请求前的内存副本中，`resource/` 下的原图文件不会被修改。图像变更时卡片原地重写；图像删除时卡片随之删除。
图像处理默认开启（`include_images=true`），需要绑定兼容模型与 formatter 的 AgentScope wrapper。
通过 `components.agent_wrapper.<name>.as_llm` 配置模型，在资源 Step 上用 `agent_wrapper` 选择对应 wrapper。
原图片 Step 的 `as_llm` 覆盖项和自动选择 `as_llm.vision` 的逻辑由此绑定方式替代。
不再单独调用 caption 模型或执行额外的 schema 提取；Agent 失败后也不以纯文本重跑。
这是一次 Agent 工作流，工具调用可能带来多轮模型请求。
每次解读图片都会新建会话，处理记录可通过返回的 `agent_session_id` 查找。更新同一张图片时，仍然修改原来的卡片。
卡片正文应包含原图引用和 `## Caption` 下的描述或文字转录，不能留空或直接写入 JSON。
`status` 留给后续流程填写，更新卡片时保留原值。
自定义图片提示词使用 `prompt_dict.resource_instructions`，中文使用 `resource_instructions_zh`；旧配置中的
`user_message` / `user_message_zh` 需相应改名。公共创建或更新模板通过
`{resource_instructions}` 插入图片要求；旧模板没有该占位符时，图片要求会追加到末尾。
在 `auto_resource` 调用或 Job 默认值中设置 `include_images=false`，会跳过图片的**全部事件，包括删除**。
调用参数优先于 Job 默认值，两者都未设置时默认开启。监听任务可设置 `jobs.resource_watch_loop.include_images=false`，
手动任务默认值可设置 `jobs.auto_resource.include_images=false`。图片子类通过现有逐资源结果和 warning 日志说明跳过原因，
不影响文本处理。已有图片卡片保持不变，即使原图被删除也不清理。重新开启不会自动补处理旧事件，需要显式把相关路径再次提交给
`auto_resource`。尊重 wrapper 配置的图片数量上限，每次资源调用至少需要容纳一张图片，不会自动提高上限。
在启动常驻服务时配置 wrapper，例如将每个 Agent 上下文的图片上限设为一张：
```bash
reme start components.agent_wrapper.default.context_config.max_image_num=1
```
监听任务会自动处理资源变更。如需显式重新处理已存在的 `resource/photo.png`，在另一个终端使用同一 workspace 调用客户端：
```bash
reme auto_resource include_images=true changes='[{"path":"resource/photo.png","change":"modified"}]'
```
宽或高超过 2048px 的图像会降采样，格式不被模型接受的图像会转码；这些处理只发生在请求前的内存副本中，
`resource/` 下的原图文件不会被修改。图像处理开启时，图像变更会原地更新卡片，图像删除会清理关联卡片。
在完整解码前，系统会检查图像尺寸，默认上限为 40,000,000 像素；超限图像或 Pillow
decompression-bomb 警告只会导致当前资源失败。缩放或转码前，会按 EXIF orientation 校正仅用于请求的内存副本。
