Core Workflows

核心工作流

1. Send Messages to Channels

1. 向频道发送消息

When to use: User wants to post a message to a Slack channel or DM

Tool sequence:

```
SLACK_FIND_CHANNELS
```
- Resolve channel name to channel ID [Prerequisite]
```
SLACK_LIST_ALL_CHANNELS
```
- Fallback if FIND_CHANNELS returns empty/ambiguous results [Fallback]
```
SLACK_FIND_USERS
```
- Resolve user for DMs or @mentions [Optional]
```
SLACK_OPEN_DM
```
- Open/reuse a DM channel if messaging a user directly [Optional]
```
SLACK_SEND_MESSAGE
```
- Post the message with resolved channel ID [Required]
```
SLACK_UPDATES_A_SLACK_MESSAGE
```
- Edit the posted message if corrections needed [Optional]

Key parameters:

```
channel
```
: Channel ID or name (without '#' prefix)
```
markdown_text
```
: Preferred field for formatted messages (supports headers, bold, italic, code blocks)
```
text
```
: Raw text fallback (deprecated in favor of markdown_text)
```
thread_ts
```
: Timestamp of parent message to reply in a thread
```
blocks
```
: Block Kit layout blocks (deprecated, use markdown_text)

Pitfalls:

```
SLACK_FIND_CHANNELS
```
requires
```
query
```
param; missing it errors with "Invalid request data provided"
```
SLACK_SEND_MESSAGE
```
requires valid channel plus one of markdown_text/text/blocks/attachments
Invalid block payloads return error=invalid_blocks (max 50 blocks)
Replies become top-level posts if
```
thread_ts
```
is omitted
Persist
```
response.data.channel
```
and
```
response.data.message.ts
```
from SEND_MESSAGE for edit/thread operations

适用场景：用户需要向Slack频道或直接消息（DM）发送内容

工具执行序列:

```
SLACK_FIND_CHANNELS
```
- 将频道名称解析为频道ID [前置步骤]
```
SLACK_LIST_ALL_CHANNELS
```
- 若FIND_CHANNELS返回空结果或模糊结果时的备选方案 [备选]
```
SLACK_FIND_USERS
```
- 解析直接消息或@提及的用户信息 [可选]
```
SLACK_OPEN_DM
```
- 若直接给用户发消息，打开或复用DM频道 [可选]
```
SLACK_SEND_MESSAGE
```
- 使用解析后的频道ID发送消息 [必填]
```
SLACK_UPDATES_A_SLACK_MESSAGE
```
- 若需修正内容，编辑已发送的消息 [可选]

关键参数:

```
channel
```
: 频道ID或名称（无需加'#'前缀）
```
markdown_text
```
: 格式化消息的首选字段（支持标题、粗体、斜体、代码块）
```
text
```
: 纯文本备选字段（已被markdown_text替代）
```
thread_ts
```
: 父消息的时间戳，用于在线程中回复
```
blocks
```
: Block Kit布局块（已被markdown_text替代）

常见陷阱:

```
SLACK_FIND_CHANNELS
```
需要
```
query
```
参数；若缺失会返回“Invalid request data provided”错误
```
SLACK_SEND_MESSAGE
```
需要有效的频道ID，且必须提供markdown_text/text/blocks/attachments中的一个
无效的block负载会返回error=invalid_blocks错误（最多支持50个block）
若省略
```
thread_ts
```
，回复会成为顶级消息
请保存SEND_MESSAGE响应中的
```
response.data.channel
```
和
```
response.data.message.ts
```
，用于后续编辑或线程操作

2. Search Messages and Conversations

2. 搜索消息和对话

When to use: User wants to find specific messages across the workspace

Tool sequence:

```
SLACK_FIND_CHANNELS
```
- Resolve channel for scoped search with
```
in:#channel
```
[Optional]
```
SLACK_FIND_USERS
```
- Resolve user for author filter with
```
from:@user
```
[Optional]
```
SLACK_SEARCH_MESSAGES
```
- Run keyword search across accessible conversations [Required]

SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION

- Expand threads for relevant hits [Required]

Key parameters:

query

: Search string supporting modifiers (

in:#channel

from:@user

before:YYYY-MM-DD

after:YYYY-MM-DD

has:link

has:file

)

```
count
```
: Results per page (max 100), or total with auto_paginate=true
```
sort
```
: 'score' (relevance) or 'timestamp' (chronological)
```
sort_dir
```
: 'asc' or 'desc'

Pitfalls:

Validation fails if
```
query
```
is missing/empty
```
ok=true
```
can still mean no hits (
```
response.data.messages.total=0
```
)

Matches are under

response.data.messages.matches

(sometimes also

response.data_preview.messages.matches

)

```
match.text
```
may be empty/truncated; key info can appear in
```
matches[].attachments[]
```
Thread expansion via FETCH_MESSAGE_THREAD can truncate when
```
response.data.has_more=true
```
; paginate via
```
response_metadata.next_cursor
```

适用场景：用户需要在工作区内查找特定消息

工具执行序列:

```
SLACK_FIND_CHANNELS
```
- 解析频道ID，用于限定搜索范围（使用
```
in:#channel
```
参数） [可选]
```
SLACK_FIND_USERS
```
- 解析用户ID，用于作者筛选（使用
```
from:@user
```
参数） [可选]
```
SLACK_SEARCH_MESSAGES
```
- 在可访问的对话中执行关键词搜索 [必填]

SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION

- 展开相关结果的线程对话 [必填]

关键参数:

query

: 支持修饰符的搜索字符串（

in:#channel

from:@user

before:YYYY-MM-DD

after:YYYY-MM-DD

has:link

has:file

）

```
count
```
: 每页结果数量（最大100），或设置auto_paginate=true获取全部结果
```
sort
```
: 排序方式（'score'按相关性排序，'timestamp'按时间排序）
```
sort_dir
```
: 排序方向（'asc'升序，'desc'降序）

常见陷阱:

若
```
query
```
缺失或为空，会验证失败
```
ok=true
```
仍可能表示无匹配结果（
```
response.data.messages.total=0
```
）

匹配结果位于

response.data.messages.matches

中（有时也会在

response.data_preview.messages.matches

）

```
match.text
```
可能为空或被截断；关键信息可能出现在
```
matches[].attachments[]
```
中
当
```
response.data.has_more=true
```
时，通过FETCH_MESSAGE_THREAD展开线程会被截断；需通过
```
response_metadata.next_cursor
```
进行分页

3. Manage Channels and Users

3. 管理频道和用户

When to use: User wants to list channels, users, or workspace info

Tool sequence:

```

```
```
limit
```
: Results per page (default varies; set explicitly for large workspaces)
```
types
```
: Channel types filter ('public_channel', 'private_channel', 'im', 'mpim')

Pitfalls:

Workspace metadata is nested under
```
response.data.team
```
, not top-level
```
SLACK_LIST_ALL_CHANNELS
```
returns public channels only; use
```
SLACK_LIST_CONVERSATIONS
```
for private/IM coverage
```
SLACK_LIST_ALL_USERS
```
can hit HTTP 429 rate limits; honor Retry-After header
Always paginate via
```
response_metadata.next_cursor
```
until empty; de-duplicate by
```
id
```

适用场景：用户需要列出频道、用户或工作区信息

工具执行序列:

```

```
: 每页结果数量（默认值不固定；针对大型工作区请显式设置）
```
types
```
: 频道类型筛选器（'public_channel', 'private_channel', 'im', 'mpim'）

常见陷阱:

工作区元数据嵌套在
```
response.data.team
```
下，而非顶级
```
SLACK_LIST_ALL_CHANNELS
```
仅返回公开频道；若需获取私有频道/直接消息，请使用
```
SLACK_LIST_CONVERSATIONS
```
```
SLACK_LIST_ALL_USERS
```
可能触发HTTP 429限流；请遵循Retry-After响应头
需持续通过
```
response_metadata.next_cursor
```
分页，直到游标为空；通过
```
id
```
去重跨页结果

4. React to and Thread Messages

4. 消息反应和线程对话管理

When to use: User wants to add reactions or manage threaded conversations

Tool sequence:

SLACK_SEARCH_MESSAGES

SLACK_FETCH_CONVERSATION_HISTORY

- Find the target message [Prerequisite]

```

```
channel
```
: Channel ID where the message lives
```
timestamp
```
/
```
ts
```
: Message timestamp (unique identifier like '1234567890.123456')
```
name
```
: Emoji name without colons (e.g., 'thumbsup', 'wave::skin-tone-3')
```
thread_ts
```
: Parent message timestamp for threaded replies

Pitfalls:

Reactions require exact channel ID + message timestamp pair
Emoji names use Slack's naming convention without colons
```
SLACK_FETCH_CONVERSATION_HISTORY
```
only returns main channel timeline, NOT threaded replies

Use

SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION

with parent's

thread_ts

to get thread replies

适用场景：用户需要添加消息反应或管理线程对话

工具执行序列:

SLACK_SEARCH_MESSAGES

或

SLACK_FETCH_CONVERSATION_HISTORY

- 定位目标消息 [前置步骤]

```
SLACK_ADD_REACTION_TO_AN_ITEM

```
name
```
: 不带冒号的表情名称（例如'thumbsup', 'wave::skin-tone-3'）
```
thread_ts
```
: 父消息的时间戳，用于线程回复

常见陷阱:

添加反应需要精确的频道ID + 消息时间戳组合
表情名称需使用Slack的命名规范，不带冒号
```
SLACK_FETCH_CONVERSATION_HISTORY
```
仅返回频道主时间线，不包含线程回复

需使用

SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION

并传入父消息的

thread_ts

来获取线程回复

5. Schedule Messages

5. 定时发送消息

When to use: User wants to schedule a message for future delivery

Tool sequence:

```
SLACK_FIND_CHANNELS
```
- Resolve channel ID [Prerequisite]
```

```
: Resolved channel ID
```
post_at
```
: Unix timestamp for delivery (up to 120 days in advance)
```
text
```
/
```
blocks

```
must be a Unix timestamp, not ISO 8601

适用场景：用户需要安排消息在未来发送

工具执行序列:

```
SLACK_FIND_CHANNELS
```
- 解析频道ID [前置步骤]
```
SLACK_SCHEDULE_MESSAGE
```
- 使用
```

```
时间戳安排消息发送 [必填]

关键参数:

```
channel
```
: 解析后的频道ID
```
post_at
```
: 消息发送的Unix时间戳（最多提前120天）
```
text
```
/
```
blocks
```
: 消息内容

常见陷阱:

定时发送最多支持提前120天
```
post_at
```
必须为Unix时间戳，而非ISO 8601格式

Common Patterns

通用模式

ID Resolution

ID解析

Always resolve display names to IDs before operations:

Channel name -> Channel ID:
```
SLACK_FIND_CHANNELS
```
with
```
query
```
param
User name -> User ID:
```
SLACK_FIND_USERS
```
with
```
search_query
```
or
```
email
```
DM channel:
```
SLACK_OPEN_DM
```
with resolved user IDs

在执行操作前，务必将显示名称解析为ID：

频道名称 -> 频道ID: 使用
```
SLACK_FIND_CHANNELS
```
并传入
```
query
```
参数
用户名 -> 用户ID: 使用
```
SLACK_FIND_USERS
```
并传入
```
search_query
```
或
```
email
```
参数
直接消息频道: 使用
```
SLACK_OPEN_DM
```
并传入解析后的用户ID

Pagination

分页

Most list endpoints use cursor-based pagination:

Follow
```
response_metadata.next_cursor
```
until empty
Set explicit
```
limit
```
values (e.g., 100-200) for reliable paging
De-duplicate results by
```
id
```
across pages

大多数列表接口使用基于游标的分页：

持续使用
```
response_metadata.next_cursor
```
进行分页，直到游标为空
显式设置
```
limit
```
值（例如100-200）以确保分页稳定
通过
```
id
```
对跨页结果进行去重

Message Formatting

消息格式化

Prefer
```
markdown_text
```
over
```
text
```
or
```
blocks
```
for formatted messages
Use
```
<@USER_ID>
```
format to mention users (not @username)
Use
```
\n
```
for line breaks in markdown_text

优先使用
```
markdown_text
```
而非
```
text
```
或
```
blocks
```
来格式化消息
使用
```
<@USER_ID>
```
格式提及用户（而非@用户名）
在markdown_text中使用
```
\n
```
实现换行

Known Pitfalls

已知陷阱

Channel resolution:
```
SLACK_FIND_CHANNELS
```
can return empty results if channel is private and bot hasn't been invited
Rate limits:
```
SLACK_LIST_ALL_USERS
```
and other list endpoints can hit HTTP 429; honor Retry-After header
Nested responses: Results may be nested under
```
response.data.results[0].response.data
```
in wrapped executions

Thread vs channel:

SLACK_FETCH_CONVERSATION_HISTORY

returns main timeline only; use

SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION

for thread replies

Message editing: Requires both
```
channel
```
and original message
```
ts
```
; persist these from SEND_MESSAGE response
Search delays: Recently posted messages may not appear in search results immediately
Scope limitations: Missing OAuth scopes can cause 403 errors; check with
```
SLACK_GET_APP_PERMISSION_SCOPES
```

频道解析：若频道为私有且机器人未被邀请，
```
SLACK_FIND_CHANNELS
```
可能返回空结果
限流：
```
SLACK_LIST_ALL_USERS
```
和其他列表接口可能触发HTTP 429限流；请遵循Retry-After响应头
嵌套响应：在包装执行中，结果可能嵌套在
```
response.data.results[0].response.data
```
下

线程与频道：

SLACK_FETCH_CONVERSATION_HISTORY

仅返回主时间线；需使用

SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION

获取线程回复

消息编辑：需要同时提供
```
channel
```
和原消息的
```
ts
```
；请从SEND_MESSAGE的响应中保存这两个值
搜索延迟：最近发送的消息可能不会立即出现在搜索结果中
权限范围限制：缺失OAuth权限范围会导致403错误；可通过
```
SLACK_GET_APP_PERMISSION_SCOPES
```
检查权限
