## 问题(实测)
SDK 里 100 个有摘要的符号中 **66 个是英文注释**,例如:
RegisterTool registers a tool that the LLM can call.
于是搜「注册工具」——中文受众最自然的问法——**RegisterTool 得分 0,一条都搜不到**。
更糟的是逐字匹配把噪声顶上来了:搜「注册工具」返回 24 条,排第一的是
`SetToolBlocks`(描述里有「工具」二字),`RegisterTool` 根本不在列表里。
## 修法
不改源码注释(那会让代码与文档脱节),而是在检索索引上加一层**人工标注的
中文功能词**:`tools/apidoc/keywords.json`。
- `rules`:按符号名前缀/子串批量覆盖(`Register*` 全带「注册」,`*Memory*` 带「记忆」)
- `symbols`:逐符号补充(重点 API、或规则覆盖不到的)
词只进 `api-index.json` 的 `g` 字段,**不影响页面展示**;检索结果里会显示
(「为何命中」),读者能理解排序依据。
同时把中文逐字匹配从主信号降为**弱信号**(要求 60% 以上字符命中)——
它正是噪声来源:凡是含「工具」二字的说明都会被「注册工具」匹上。
## 结果
| 查询 | 修改前 | 修改后 |
|---|---|---|
| 注册工具 | 24 条,RegisterTool 缺席 | **7 条,RegisterTool 第一** |
| 崩溃 | 1 条 | 2 条(SetAutoRestart + AutoRestart)|
| InjectText | 7 条(含重复)| 6 条 |
| memory.recall | 1 条 | 1 条(不变)|
顺带修掉索引重复:接口会同时作为 `type` 符号与接口本身被加两次
(`MemoryAPI` 等 11 个各重复一条)。现在接口只走接口那条路径,索引 200 → 189 条。
keywords.json 是**可选**的:读不到只警告不中断,检索退化为原行为。

# 输入 / 输出通道
|
||
|
||
通道是插件与外界(设备、其他 Agent、外部系统)交换消息的入口。**输入通道**接收外部消息,**输出通道**把消息投递出去。
|
||
|
||
## `IOInjector`
|
||
|
||
IOInjector provides methods for injecting input and interrupts into the agent pipeline.
|
||
All methods accept (source, channel) where channel is the target output channel
|
||
for routing the agent's response.

InjectTextOpts(source, channel, text string, opts InjectOptions)
|
||
```
|
||
|
||
以下 Opts 变体让调用点在**这一次注入**上声明记忆与裁剪行为。
|
||
|
||
上面那些不带 opts 的方法等价于传零值 InjectOptions(记入记忆 + 不裁剪),
|

保留它们是为了不破坏已有插件;新代码应当用 Opts 变体把意图写清楚。
|
||
|

```
|
||
|

SetToolBlocks 插件工具注入多模态内容块(image_url/audio_url),内核在下一条
|
||
tool message 的 content 数组里带上这些块,让模型在后续轮次看到图/听到音频。

### `ChannelDef`
|
||
|
||
```go
|
||
type ChannelDef struct { NoMemory bool `json:"no_memory,omitempty"` Cleaner func(string) string `json:"-"` ContextPolicy string `json: …
|
||
```
|
||
|
||
ChannelDef 描述通道在记忆计算层的行为,与 ToolDef.NoMemory/Cleaner 语义一致。
|
||
NoMemory: 此通道输入/输出不参与记忆计算(向量化/关键词提取/蒸馏),但原文保留在上下文中
|
||
Cleaner: 计算层过滤函数,不改原文;仅在向量化/jieba/蒸馏/存档提取关键词时调用
|
||
ContextPolicy: 此通道的输入到达后是否据此裁剪上下文,默认 none(不裁剪)
|
||
RecallPolicy: 此通道的输入到达后是否据此召回相关记忆,默认 auto(召回)
|
||
|
||
JSON tag 是必需的:通道定义要跨进程传给内核,而 Cleaner 是函数(必须忽略)。
|
||
没有 tag 时既无法整体 marshal(func 不支持),又会诱使调用方手写字段白名单——
|
||
那样新增字段会被静默丢掉。
|
||
|
||
<small>`plugin.go:139`</small>
|
||
|
||
### `ContextPolicyNone`
|
||
|
||
```go
|
||
const ContextPolicyNone
|
||
```
|
||
|
||
上下文策略:决定一次工具调用/输入/注入是否依据其内容裁剪上下文。
|
||
|
||
默认(空串或 ContextPolicyNone)**不裁剪**:裁剪会归档丢弃低相关事件,
|
||
必须由工具/通道/注入点显式声明才发生——否则一个只想往上下文里塞内容的
|
||
插件会在背后把别人的内容挤掉,且看不出是谁干的。
|
||
|
||
<small>`plugin.go:44`</small>
|
||
|
||
### `ContextPolicyPrune`
|
||
|
||
```go
|
||
const ContextPolicyPrune
|
||
```
|
||
|
||
上下文策略:决定一次工具调用/输入/注入是否依据其内容裁剪上下文。
|
||
|
||
默认(空串或 ContextPolicyNone)**不裁剪**:裁剪会归档丢弃低相关事件,
|
||
必须由工具/通道/注入点显式声明才发生——否则一个只想往上下文里塞内容的
|
||
插件会在背后把别人的内容挤掉,且看不出是谁干的。

### `PluginSDK.InjectInputMedia`
|
||
|
||
```go
|
||
func (s *PluginSDK) InjectInputMedia(source, channel, text string, blocks []ContentBlock)
|
||
```
|
||
|
||
InjectInputMedia 注入带媒体内容块(image_url/audio_url)的输入。
|
||
blocks 会落进媒体存储被记忆引用捕获,同时作为当前轮 content 数组
|
||
发给 LLM,让模型在「本轮」就看到图/听到音频——区别于 SetToolBlocks
|
||
的「下一轮 tool message」语义。
|
||
等价于 InjectInputMediaOpts(..., InjectOptions{})。
|
||
|
||
<small>`plugin.go:701`</small>
|
||
|
||
### `PluginSDK.InjectInputMediaOpts`

|
||
|
||
<small>`plugin.go:740`</small>

|
||
```
|
||
|
||

|
||
等价于 InjectInputMediaSyncOpts(..., InjectOptions{})。

### `PluginSDK.InjectInputSync`
|
||
|
||
```go
|
||
func (s *PluginSDK) InjectInputSync(source, channel, text string) string
|
||
```
|
||
|
||
InjectInputSync injects a text message and synchronously waits for the agent reply,
|
||
returning the reply text (empty string if none). Replies must be dispatched back
|
||
to the source channel by the caller.
|
||
|
||
**示例插件里的真实用法**
|
||
|
||
| 插件 | 位置 | 代码 |

|
||
```
|
||
|
||
InjectInterruptMedia 注入带媒体内容块的中断,可抢占当前 LLM 处理。
|
||
blocks 随中断消息一起发给模型。
|
||
|
||
<small>`plugin.go:764`</small>
|
||
|
||
### `PluginSDK.InjectInterruptMediaOpts`
|
||
|
||
```go
|
||
func (s *PluginSDK) InjectInterruptMediaOpts(source, channel, text string, blocks []ContentBlock, opts InjectOptions)
|
||
```
|
||
|
||
InjectInterruptMediaOpts 注入带媒体块的中断,并声明记忆/裁剪行为。
|
||
|
||
<small>`plugin.go:756`</small>
|
||
|
||
### `PluginSDK.InjectInterruptText`
|
||
|
||
```go
|
||
func (s *PluginSDK) InjectInterruptText(source, channel, text string)
|
||
```
|
||
|
||
InjectInterruptText injects a text interrupt that can preempt current LLM processing.
|
||
等价于 InjectInterruptTextOpts(..., InjectOptions{}):记入记忆、不裁剪。
|
||
|
||
<small>`plugin.go:673`</small>
|
||
|
||
### `PluginSDK.InjectInterruptTextOpts`
|
||
|
||
```go
|
||
func (s *PluginSDK) InjectInterruptTextOpts(source, channel, text string, opts InjectOptions)
|
||
```
|
||
|
||
InjectInterruptTextOpts 注入可抢占当前处理的中断文本。
|
||
|
||
中断也允许声明 ContextPolicyPrune:中断同样携带内容进入上下文,
|
||
是否需要据此裁剪由调用方决定(默认不裁剪)。
|
||
|
||
**示例插件里的真实用法**
|
||
|
||
| 插件 | 位置 | 代码 |
|
||
|---|---|---|
|
||
| [`browser`](../examples/index.md#browser) | `example/browser/plugin.go:1319` | `p.sdk.InjectInterruptTextOpts(p.name, p.name,` |
|
||
| [`calendar`](../examples/index.md#calendar) | `example/calendar/plugin.go:527` | `p.sdk.InjectInterruptTextOpts("calendar", "calendar", msg, sdk.InjectOptions{NoMemory: true})` |
|
||
| [`memo`](../examples/index.md#memo) | `example/memo/plugin.go:299` | `p.sdk.InjectInterruptTextOpts(p.name, p.name,` |
|
||
| [`qq`](../examples/index.md#qq) | `example/qq/plugin.go:1493` | `p.sdk.InjectInterruptTextOpts(p.name, p.name, text, sdk.InjectOptions{` |
|
||
|
||
<small>`plugin.go:724`</small>
|
||
|
||
### `InjectOptions`
|
||
|
||
```go
|
||
type InjectOptions struct { NoMemory bool ContextPolicy string // RecallPolicy 声明此次注入是否据其内容召回相关记忆。 // 空串 = 默认(输入/注<><E6B3A8> …
|
||
```
|
||
|
||
InjectOptions 声明一次注入行为在记忆层与上下文层的表现。
|
||
|
||
零值 = 记入记忆 + 不裁剪上下文,与历史行为(三参数注入方法)完全一致,
|
||
因此调用方只有在确实需要改变行为时才需要填它。
|
||
|
||
为什么注入也要这两个标志:注入的内容来源千差万别——轮询到的频道消息
|
||
属于真实对话(该记),而“任务还在跑”“连接已重连”这类提醒不该污染记忆,
|
||
也不该把上下文按它的内容裁一遍。按调用点声明比按通道一刀切准确。
|
||
|
||
NoMemory: 此次注入不参与记忆计算(向量化/关键词提取/蒸馏),原文仍留在上下文
|
||
ContextPolicy: 此次注入后是否依据(清洗后的)内容裁剪上下文;默认不裁剪。
|
||
RecallPolicy: 此次注入是否依据(清洗后的)内容召回相关记忆;默认 auto(召回)。
|
||
|
||
中断注入也允许声明 prune——它同样会携带内容进入上下文。
|
||
|
||
CleanerName: 此次注入的内容用哪个**已注册的通道 cleaner** 清洗。
|
||
|
||
空串 = 按注入的 source 查通道定义(既有行为)。
|
||
为什么要能显式指定:注入的 source 未必是注册过的输入通道名,
|
||
而注入内容往往带 ANSI/JSON 包装,需要清洗后才是有效内容;
|
||
不指定就只能退到「按 source 查不到就不清洗」。

||

### `PluginSDK.InjectText`
|
||
|
||
```go
|
||
func (s *PluginSDK) InjectText(source, channel, text string)
|
||
```
|
||
|
||
InjectText injects a text message into the agent pipeline.
|
||
等价于 InjectTextOpts(..., InjectOptions{}):记入记忆、不裁剪。
|
||
|
||
<small>`plugin.go:679`</small>
|
||
|
||
### `PluginSDK.InjectTextNoMemory`
|
||
|
||
```go
|
||
func (s *PluginSDK) InjectTextNoMemory(source, channel, text string)
|
||
```
|
||
|
||
InjectTextNoMemory injects a text message without generating memory.
|
||
等价于 InjectTextOpts(..., InjectOptions{NoMemory: true})。
|
||
|
||
**示例插件里的真实用法**
|
||
|
||
| 插件 | 位置 | 代码 |
|
||
|---|---|---|
|
||
| [`browser`](../examples/index.md#browser) | `example/browser/plugin.go:1114` | `p.sdk.InjectTextNoMemory(p.name, p.name, fmt.Sprintf("[浏览器 %s 已导航到 %s]", id, rawURL))` |
|
||
|
||
<small>`plugin.go:685`</small>
|

### `PluginSDK.InjectTextOpts`
|
||
|

|
||
|
||
InjectTextOpts 注入文本到 agent,并在这一次注入上声明记忆与裁剪行为。
|
||
|
||
<small>`plugin.go:714`</small>

|
||
### `PriorityL1`
|
||
|
||
```go
|
||
const PriorityL1
|
||
```
|
||
|
||

### `PluginSDK.RegisterInputChannel`
|
||
|
||
```go
|
||
func (s *PluginSDK) RegisterInputChannel(name string, def ChannelDef) error
|
||
```
|
||
|
||
RegisterInputChannel registers an input channel with its memory behavior.
|
||
|
||
契约:**凡是用 InjectText*/InjectInput*/InjectInterrupt*(source, "<name>", ...)
|
||
注入的通道名,都应当在这里登记**。inputch 是内核里最基本的**输入路由单位**:
|
||
只有登记过的通道才能在 inputch 登记表里出现,父 agent 才能"把某个 inputch 划给驻留子";
|
||
没登记就划分会直接失败(`inputch 未注册`)。
|
||
|
||
只登记输出通道(RegisterOutputChannel)而没登记输入通道时,内核会兜底登记同名
|
||
inputch 并打告警日志 —— 兜底只为兼容老插件,新插件请显式登记。
|
||
|
||
def.NoMemory: 此通道输入不参与记忆计算
|
||
def.Cleaner: 计算层对输入文本清洗后(不改原文)再向量化/提关键词

**示例插件里的真实用法**
|
||
|
||
| 插件 | 位置 | 代码 |
|
||
|---|---|---|
|
||
| [`a2a`](../examples/index.md#a2a) | `example/a2a/plugin.go:52` | `_ = s.RegisterInputChannel(p.name, sdk.ChannelDef{})` |
|
||
| [`acp`](../examples/index.md#acp) | `example/acp/plugin.go:52` | `_ = s.RegisterInputChannel(p.name, sdk.ChannelDef{})` |
|
||
| [`browser`](../examples/index.md#browser) | `example/browser/plugin.go:209` | `_ = s.RegisterInputChannel(p.name, sdk.ChannelDef{})` |
|
||
| [`calendar`](../examples/index.md#calendar) | `example/calendar/plugin.go:281` | `_ = s.RegisterInputChannel("calendar", sdk.ChannelDef{NoMemory: true})` |
|
||
|
||
<small>`plugin.go:561`</small>
|
||
|
||
### `PluginSDK.RegisterOutputChannel`
|
||
|
||
```go
|
||
func (s *PluginSDK) RegisterOutputChannel(name string, caps int, desc string, def ChannelDef, handler ToolHandler) error
|
||
```
|
||
|
||
RegisterOutputChannel registers an output channel that the output_send tool can route to.
|
||
|
||
与 RegisterInputChannel 的分工:本函数声明**出站**(output_send__<name> 的回复发给谁);
|
||
入站(谁会往 <name> 注入输入)是另一件事,用 RegisterInputChannel 声明。
|
||
若该通道同时也是你的注入入口,两个都要登记。
|
||
|
||
name: channel name (e.g. "qq", "webui")。
|
||
|
||
❗**命名约束**:内核会把通道名拼进 LLM 的函数名(`output_send__<name>`),
|
||
而上游对函数名的规范是 `^[a-zA-Z0-9_-]{1,64}$`。违反的后果不是"这个工具不可用",
|
||
而是**整条请求被上游 400 拒绝**(`Invalid 'tools[N].function.name'`),
|
||
网关的 auto tier 会全链条失败 —— 表现成"整个 agent 不说话了"。
|
||
所以通道名只能用 `[A-Za-z0-9_-]`,且总长要留出 `output_send__`(13 字符)的余量。
|
||
若通道名来自外部输入(设备自报 id 之类),请**在插件侧派生一个合规且唯一的名字**,
|
||
而不是把原始值直接当通道名。
|
||
caps: bitmask of supported output capabilities (CapText, CapFile, etc.)
|
||
desc: description of the channel, expected meta format, and type enum
|
||
def: 通道在记忆计算层的行为(NoMemory/Cleaner)
|
||
handler: receives args map with keys: payload (string), type (string), meta (string|optional)

### `PluginSDK.SetToolBlocks`
|
||
|
||
```go
|
||
func (s *PluginSDK) SetToolBlocks(blocks []ContentBlock)
|
||
```
|
||
|
||
SetToolBlocks 在工具处理函数内注入多模态内容块,内核在下一条 tool message
|
||
的 content 数组里带上它们。需要「本轮就让模型看到」时用 InjectInputMedia。
