# Agent Note: Narrow Web image input version one
|
||||
|
||||
Status: implemented
|
||||

||||
English | [中文](2026-07-29-narrow-web-image-input-v1.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The first durable Web image-input slice also introduced speculative surfaces for multiple-image transactions, arbitrary CLI provider mounting, output-modality discovery, alternative text, and provider-neutral visual token pricing. None was required to paste or drop one image, persist it before its message event, replay it through a visual adapter, or render it from authorized history. Keeping those surfaces would turn unchosen future behavior into public contracts and make the initial capability harder to review and maintain.
|
||||
|
||||
## Decision
|
||||
|
||||
Version one accepts at most one image in a submitted prompt. The client gives immediate feedback, the host enforces the invariant, and the attachment seam validates and commits that one object. Deployment configuration retains per-image byte and pixel limits; request buffering derives from the per-image byte limit. There is no batch prevalidation, aggregate byte limit, image-count setting, transaction layer, or rollback protocol.
|
||||
|
||||
The CLI only patches the selected provider and model. The boot composition must already register the route, as it does for the shipped DeepSeek, OpenAI, and Anthropic routes; the CLI does not inspect the yml provider roster or dynamically mount an adapter.
|
||||
|
||||
Exact-model metadata carries only the input modalities that current admission decisions consume. `ImageBlock` carries the durable attachment reference; its optional display name supplies accessible UI text, so the core block has no separate alternative-text field. Provider-neutral token estimation does not apply one provider's visual pricing formula to other routes.
|
||||
|
||||
The attachment seam exposes its limits plus `saveImage` and `readImage`. The host depends on that seam rather than implementation re-exports. Browser draft and historical-image operations remain concrete conversation-plugin internals; the public `IConversation` face contains only the input registry and the scoped send, cancel, and history verbs used across package boundaries.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Keep multiple images and add transaction or rollback machinery.** Without garbage collection, a partially persisted batch needs an ownership or reclamation design. One image satisfies the initial user path without creating that lifecycle.
|
||||
|
||||
**Keep future-facing fields and methods as placeholders.** Output modalities, block alternative text, batch validation, and active-model handshake data had no current decision consumer. Adding them later with their first consumer preserves freedom to choose the correct contract.
|
||||
|
||||
**Estimate every image with one tile formula.** Visual pricing varies by provider, model, detail mode, and preprocessing. A hard-coded provider-neutral estimate would look authoritative while being wrong; provider usage is the authoritative accounting source.
|
||||
|
||||
**Mount any CLI-selected provider dynamically.** Configuration already owns plugin composition and credentials. Making selection also mutate composition duplicates that responsibility and requires parsing the config tree outside the loader.
|
||||
|
||||
## Consequences
|
||||
|
||||
The initial feature has fewer public fields, lifecycle operations, configuration knobs, and route-assembly branches. A prompt needing multiple images is rejected and must wait for an explicit multi-image persistence design. A provider absent from the composition cannot be selected solely with CLI flags. Pre-request token pressure may undercount visual input until a provider-aware estimator is designed, while reported usage remains exact.
|
||||
|
||||
Reintroducing any removed surface requires a concrete consumer and its failure, lifecycle, replay, and testing contract rather than compatibility with this pre-release shape.

# Agent Note: 收窄 Web 图片输入第一版
|
||||
|
||||
Status: implemented

|
||||
## 问题
|
||||
|
||||
首个持久化 Web 图片输入切片还引入了多张图片事务、由 CLI（命令行界面）挂载任意提供方、输出模态发现、替代文本以及与提供方无关的视觉 token 定价等推测性表面。要实现粘贴或拖放一张图片、在其消息事件之前将其持久化、通过视觉适配器回放它，或从经授权的历史记录中渲染它，并不需要上述任何表面。保留这些表面会把尚未选择的未来行为变成公共契约，并使初始能力更难评审和维护。
|
||||
|
||||
## 决策
|
||||
|
||||
第一版在每条提交的提示词中最多接受一张图片。客户端立即提供反馈，宿主强制执行该不变量，附件服务边界则校验并提交这一个对象。部署配置保留单张图片的字节和像素限制；请求缓冲上限由单张图片的字节限制派生。不设批量预校验、总字节限制、图片数量设置、事务层或回滚协议。
|
||||
|
||||
CLI 只修改选定的提供方和模型。启动组合必须已经注册该路由，随项目交付的 DeepSeek、OpenAI 和 Anthropic 路由正是如此；CLI 不会检查 yml 提供方清单，也不会动态挂载适配器。
|
||||
|
||||
确切模型元数据只携带当前准入决策会消费的输入模态。`ImageBlock` 携带持久附件引用；其可选显示名称提供无障碍 UI 文本，因此核心块没有单独的替代文本字段。与提供方无关的 token 估算不会把某一提供方的视觉定价公式应用于其他路由。
|
||||
|
||||
附件服务边界公开其限制以及 `saveImage` 和 `readImage`。宿主依赖该服务边界，而不是实现层重新导出的内容。浏览器草稿和历史图片操作仍是具体会话插件的内部实现；公开的 `IConversation` 表面只包含输入注册表，以及跨包边界使用的按作用域发送、取消和历史记录操作。
|
||||
|
||||
## 曾考虑的替代方案
|
||||
|
||||
**保留多张图片，并添加事务或回滚机制。** 没有垃圾回收时，部分持久化的批次需要一套所有权或回收设计。一张图片即可满足首个用户路径，而不引入该生命周期。
|
||||
|
||||
**将面向未来的字段和方法保留为占位符。** 输出模态、块替代文本、批量校验和活跃模型握手数据目前都没有决策消费方。等到第一个消费方出现时再加入这些内容，可以保留选择正确契约的自由。
|
||||
|
||||
**使用一种图块公式估算每张图片。** 视觉定价因提供方、模型、细节模式和预处理而异。一项硬编码且与提供方无关的估算会看似权威，实际却是错误的；提供方用量才是权威核算来源。
|
||||
|
||||
**动态挂载 CLI 选择的任意提供方。** 配置已经负责插件组合和凭据。让选择操作同时改变组合会造成职责重复，并要求在加载器之外解析配置树。
|
||||
|
||||
## 后果
|
||||
|
||||
初始功能具有更少的公开字段、生命周期操作、配置项和路由组装分支。需要多张图片的提示词会被拒绝，必须等待明确的多张图片持久化设计。未加入组合的提供方无法仅凭 CLI 标志选择。在设计出提供方感知型估算器之前，请求前的 token 压力计算可能少计视觉输入，而上报的用量仍保持精确。
|
||||
|
||||
重新引入任何已移除表面时，都必须有具体消费方，并为其定义失败、生命周期、回放和测试契约，而不是为了兼容这一预发布形态。

# Agent Note: Simplify Web image input version one
|
||||
|
||||
Status: implemented
|
||||
|
||||
English | [中文](2026-07-29-simplify-web-image-input-v1.zh.md)
|
||||
|
||||
## Problem
|
||||
|
||||
The first durable Web image-input slice introduced required ordered multi-image intake alongside speculative surfaces for arbitrary CLI provider mounting, output-modality discovery, alternative text, provider-neutral visual token pricing, and browser lifecycle APIs with no cross-package consumer. Keeping the speculative surfaces would turn unchosen future behavior into public contracts and make the initial capability harder to review and maintain.
|
||||
|
||||
## Decision
|
||||
|
||||
Version one accepts ordered image batches bounded by configurable per-message count and aggregate-byte limits plus per-image byte and pixel limits. The client gives immediate feedback, while the host authoritatively decodes the complete batch, checks its bounds, validates every image without storage writes, and only then saves every image while preserving submitted order in the resulting durable blocks. Request buffering derives from the aggregate image-byte limit. This preserves validation atomicity without adding a batch transaction or rollback protocol.
|
||||
|
||||
The CLI only patches the selected provider and model. The boot composition must already register the route, as it does for the shipped DeepSeek, OpenAI, and Anthropic routes; the CLI does not inspect the yml provider roster or dynamically mount an adapter.
|
||||
|
||||
Exact-model metadata carries only the input modalities that current admission decisions consume. `ImageBlock` carries the durable attachment reference; its optional display name supplies accessible UI text, so the core block has no separate alternative-text field. Provider-neutral token estimation does not apply one provider's visual pricing formula to other routes.
|
||||
|
||||
The attachment seam exposes its limits plus storage-free `validateImage`, `saveImage`, and `readImage`. The host depends on that seam rather than implementation re-exports. Browser draft and historical-image operations remain concrete conversation-plugin internals; the public `IConversation` face contains only the input registry and the scoped send, cancel, and history verbs used across package boundaries.
|
||||
|
||||
## Alternatives considered
|
||||
|
||||
**Accept only one image.** Comparing or combining several images is a current product requirement. Count and aggregate-byte bounds keep that path finite without reducing it to a single image.
|
||||
|
||||
**Add a storage transaction or rollback protocol.** Storage-free validation prevents malformed later members from leaving earlier valid members unreferenced. Stronger all-or-nothing storage across independent content-addressed objects would require ownership or reclamation semantics that the current product path does not need.
|
||||
|
||||
**Keep future-facing fields and methods as placeholders.** Output modalities, block alternative text, and active-model handshake data had no current decision consumer. Adding them later with their first consumer preserves freedom to choose the correct contract.
|
||||
|
||||
**Estimate every image with one tile formula.** Visual pricing varies by provider, model, detail mode, and preprocessing. A hard-coded provider-neutral estimate would look authoritative while being wrong; provider usage is the authoritative accounting source.
|
||||
|
||||
**Mount any CLI-selected provider dynamically.** Configuration already owns plugin composition and credentials. Making selection also mutate composition duplicates that responsibility and requires parsing the config tree outside the loader.
|
||||
|
||||
## Consequences
|
||||
|
||||
The feature retains the two batch limits and one storage-free validation method required by multi-image prompts, while removing unrelated public fields, lifecycle operations, and route-assembly branches. A provider absent from the composition cannot be selected solely with CLI flags. Pre-request token pressure may undercount visual input until a provider-aware estimator is designed, while reported usage remains exact.

# Agent Note: 简化 Web 图片输入第一版

|

## 问题
|
||||
|
||||
首个持久化 Web 图片输入切片在引入按顺序接收多张图片的必需能力时，也引入了由 CLI（命令行界面）挂载任意提供方、输出模态发现、替代文本、提供方无关的视觉 token 定价，以及没有跨包（package）消费方的浏览器生命周期 API 等推测性表面。保留这些推测性表面会把尚未选择的未来行为变成公共契约，并使初始能力更难评审和维护。
|
||||
|
||||
## 决策
|
||||
|
||||
第一版接受有序图片批次，并以可配置的每条消息图片数量与图片总字节数上限，以及单张图片字节数与像素上限约束批次。客户端立即提供反馈，而宿主会以权威方式解码完整批次、检查各项上限、在不写入存储的情况下校验每张图片，之后才保存每张图片，并在生成的持久图片块中保留提交顺序。请求缓冲上限由图片总字节数上限派生。这样无需添加批次事务或回滚协议，就能保持校验的原子性。
|
||||
|
||||
CLI 只修改选定的提供方和模型。启动组合必须已经注册该路由，随项目交付的 DeepSeek、OpenAI 和 Anthropic 路由正是如此；CLI 不会检查 yml 提供方清单，也不会动态挂载适配器。
|
||||
|
||||
确切模型元数据只携带当前准入决策会消费的输入模态。`ImageBlock` 携带持久附件引用；其可选显示名称提供无障碍 UI 文本，因此核心块没有单独的替代文本字段。与提供方无关的 token 估算不会把某一提供方的视觉定价公式应用于其他路由。
|
||||
|
||||
附件服务边界公开其限制、不触碰存储的 `validateImage`，以及 `saveImage` 和 `readImage`。宿主依赖该服务边界，而不是实现层重新导出的内容。浏览器草稿和历史图片操作仍是具体会话插件的内部实现；公开的 `IConversation` 表面只包含输入注册表，以及跨包边界使用的按作用域发送、取消和历史记录操作。
|
||||
|
||||
## 曾考虑的替代方案
|
||||
|
||||
**只接受一张图片。** 比较或组合多张图片是当前产品要求。图片数量和总字节数上限使这条路径保持有界，而无需将其缩减为单张图片。
|
||||
|
||||
**添加存储事务或回滚协议。** 不触碰存储的校验能防止后面的畸形成员使前面有效的成员成为无引用对象。若要在独立的内容寻址对象之间实现更强的全有或全无存储保证，就需要当前产品路径并不需要的所有权或回收语义。
|
||||
|
||||
**将面向未来的字段和方法保留为占位符。** 输出模态、块替代文本和活跃模型握手数据目前都没有决策消费方。等到第一个消费方出现时再加入这些内容，可以保留选择正确契约的自由。
|
||||
|
||||

|
||||
|
||||
**动态挂载 CLI 选择的任意提供方。** 配置已经负责插件组合和凭据。让选择操作同时改变组合会造成职责重复，并要求在加载器之外解析配置树。
|
||||
|
||||
## 后果
|
||||
|
||||
该功能保留了多图片提示词所需的两个批次上限和一个不触碰存储的校验方法，同时移除了无关的公开字段、生命周期操作和路由组装分支。未加入组合的提供方无法仅凭 CLI 标志选择。在设计出提供方感知型估算器之前，请求前的 token 压力计算可能少计视觉输入，而上报的用量仍保持精确。
|
||||
|
||||
重新引入任何已移除表面时，都必须有具体消费方，并为其定义失败、生命周期、回放和测试契约，而不是为了兼容这一预发布形态。
