agent-slack（Agent Slack 搜索）

Slack automation with agent-slack

agent-slack is a CLI binary on $PATH. Invoke directly (e.g. agent-slack user list).

Installation

If agent-slack is not found on $PATH, install it:

• curl -fsSL https://raw.githubusercontent.com/stablyai/agent-slack/main/install.sh | sh (recommended)
• npm i -g agent-slack (requires Node >= 22.5)
• nix run github:stablyai/agent-slack -- <args> (no install needed, prefix all commands)

CRITICAL: Bash command formatting rules

Claude Code's permission checker has security heuristics that force manual approval prompts. Avoid these patterns to keep commands auto-allowed. See: https://github.com/anthropics/claude-code/issues/34379

1. No # anywhere in the command string. Treated as a comment delimiter even inside quotes. Use bare channel names (general not #general). No # comments in inline scripts — use the Bash tool's description parameter instead.
2. No '' (consecutive single quotes) or "" (consecutive double quotes). Triggers "potential obfuscation" check. Avoid Python empty string literals like d.get('key', '') — use d.get('key') instead.
3. Only | jq for filtering — no python3, no other commands. python3 -c is not in the allow list and triggers prompts. jq with single-quote-only expressions (no " inside) is safe:

- WRONG: agent-slack search... | python3 -c "..." (not allowed) - WRONG: agent-slack search... | jq '.a + "x"' (mixed quotes) - RIGHT: agent-slack search... | jq '.a' - RIGHT: agent-slack search... | jq '.messages[] |.ts'

1. No || or && chains. Run multiple agent-slack commands as separate Bash tool calls.
2. No file redirects (>, >>). Process JSON output directly, don't write to files.

Quick start (auth)

Authentication is automatic on macOS and Windows (Slack Desktop first, then Chrome/Firefox fallbacks on macOS).

If credentials aren’t available, run one of:

• Slack Desktop import (macOS/Windows):

agent-slack auth import-desktop
agent-slack auth test

• Chrome fallback:

agent-slack auth import-chrome
agent-slack auth test

• Firefox fallback:

agent-slack auth import-firefox
agent-slack auth test

• Or set env vars (browser tokens; avoid pasting these into chat logs):

export SLACK_TOKEN="xoxc-..."
export SLACK_COOKIE_D="xoxd-..."
agent-slack auth test

• Or set a standard token:

export SLACK_TOKEN="xoxb-..."  # or xoxp-...
agent-slack auth test

Check configured workspaces:

agent-slack auth whoami

Canonical workflow (given a Slack message URL)

1. Fetch a single message (plus thread summary, if any):

agent-slack message get "https://workspace.slack.com/archives/C123/p1700000000000000"

1. If you need the full thread:

agent-slack message list "https://workspace.slack.com/archives/C123/p1700000000000000"

Browse recent channel messages

To see what's been posted recently in a channel (channel history):

agent-slack message list "general" --limit 20
agent-slack message list "C0123ABC" --limit 10
agent-slack message list "general" --with-reaction eyes --oldest "1770165109.000000" --limit 20
agent-slack message list "general" --without-reaction dart --oldest "1770165109.000000" --limit 20
agent-slack message list "general" --resolve-users

This returns the most recent messages in chronological order. Use --limit to control how many (default 25). When using --with-reaction or --without-reaction, you must also pass --oldest to bound scanning.

Attachments (snippets/images/files)

message get/list and search auto-download attachments and include file metadata in JSON output (typically under message.files[] / files[]), including name when available and path for the local download. Failed message attachment downloads keep the attachment entry, preserve a local .download-error.txt path, and include message.files[].error for message get/list or messages[].files[].error for search messages|all; search files skips files whose download fails.

Draft a message (browser editor)

Opens a Slack-like rich-text editor in the browser for composing messages with formatting toolbar (bold, italic, strikethrough, links, lists, quotes, code, code blocks). After sending, shows a "View in Slack" link.

agent-slack message draft "general"
agent-slack message draft "general" "initial text"
agent-slack message draft "https://workspace.slack.com/archives/C123/p1700000000000000"

Send, edit, delete, or react

agent-slack message send "https://workspace.slack.com/archives/C123/p1700000000000000" "I can take this."
agent-slack message send "alerts-staging" "here's the report" --attach ./report.md
agent-slack message edit "https://workspace.slack.com/archives/C123/p1700000000000000" "I can take this today."
agent-slack message delete "https://workspace.slack.com/archives/C123/p1700000000000000"

agent-slack message send "general" "Here's the plan:
- Step 1: do the thing
- Step 2: verify it worked
  - Sub-step: check logs"
agent-slack message react add "https://workspace.slack.com/archives/C123/p1700000000000000" "eyes"
agent-slack message react remove "https://workspace.slack.com/archives/C123/p1700000000000000" "eyes"

Channel mode for edit/delete requires --ts:

agent-slack message edit "general" "Updated text" --workspace "myteam" --ts "1770165109.628379"
agent-slack message delete "general" --workspace "myteam" --ts "1770165109.628379"

Attach options for message send:

• --attach <path> upload a local file (repeatable)

message send returns channel_id plus the posted ts and a permalink (for non-attachment sends). thread_ts appears only when replying in a thread.

Mentions: just write @U05BRPTKL6A, @here, @channel, or @everyone — the CLI converts them to real Slack mention tokens and escapes literal &/</> in your text. You don't need to wrap IDs yourself.

List channels + create/invite users

agent-slack channel list
agent-slack channel list --user "@alice" --limit 50
agent-slack channel list --all --limit 100
agent-slack channel new --name "incident-war-room"
agent-slack channel new --name "incident-leads" --private
agent-slack channel invite --channel "incident-war-room" --users "U01AAAA,@alice,bob@example.com"
agent-slack channel invite --channel "incident-war-room" --users "partner@vendor.com" --external
agent-slack channel invite --channel "incident-war-room" --users "partner@vendor.com" --external --allow-external-user-invites

For --external, invite targets must be emails. By default, invitees are external-limited; add --allow-external-user-invites to allow them to invite other users.

Search (messages + files)

Prefer channel-scoped search for reliability:

agent-slack search all "smoke tests failed" --channel "alerts" --after 2026-01-01 --before 2026-02-01
agent-slack search messages "stably test" --user "@alice" --channel general
agent-slack search messages "stably test" --resolve-users
agent-slack search files "testing" --content-type snippet --limit 10

Multi-workspace guardrail (important)

If you have multiple workspaces configured and you use a channel name (e.g. general), pass --workspace (or set SLACK_WORKSPACE_URL) to avoid ambiguity:

agent-slack message get "general" --workspace "https://myteam.slack.com" --ts "1770165109.628379"
agent-slack message get "general" --workspace "myteam" --ts "1770165109.628379"

DM / group DM channels

Get the channel ID for a DM or group DM, useful for sending messages to a group of users:

agent-slack user dm-open @alice @bob
agent-slack user dm-open U01AAAA U02BBBB U03CCCC

Mark as read

Mark a channel, DM, or group DM as read up to a given message:

agent-slack channel mark "https://workspace.slack.com/archives/C123/p1700000000000000"
agent-slack channel mark "general" --workspace "myteam" --ts "1770165109.628379"
agent-slack channel mark "D0A04PB2QBW" --workspace "myteam" --ts "1770165109.628379"

To make a specific message appear unread, set --ts to just before it (subtract 0.000001). This moves the read cursor so that message and everything after it appear as new:

agent-slack channel mark "general" --workspace "myteam" --ts "1770165109.628378"

Workflows

Discover and run Slack workflows bookmarked in channels:

# List workflows in a channel
agent-slack workflow list "#ops"

# Preview trigger metadata (no side effects)
agent-slack workflow preview "Ft123ABC"

# Get workflow definition including form fields and steps
agent-slack workflow get "Ft123ABC"
agent-slack workflow get "Wf456DEF"

# Trip a workflow trigger
agent-slack workflow run "Ft123ABC" --channel "#ops"

Later (saved messages)

Manage your saved-for-later messages:

agent-slack later list
agent-slack later list --counts-only
agent-slack later list --state completed
agent-slack later complete "<message-url>"
agent-slack later archive "<message-url>"
agent-slack later reopen "<message-url>"
agent-slack later save "<message-url>"
agent-slack later remove "<message-url>"
agent-slack later remind "<message-url>" --in 1h
agent-slack later remind "<message-url>" --in tomorrow
