slk — Slack CLI

Session-based Slack CLI for macOS. Auto-authenticates from the Slack desktop app — no tokens, no OAuth, no app installs. Acts as your user (

xoxc-

session tokens).

Commands

# Auth
slk auth                              # Test authentication, show user/team

Auth

Automatic — extracts session token from Slack desktop app's LevelDB + decrypts cookie from macOS Keychain.

First run: macOS will show a Keychain dialog asking to allow access to "Slack Safe Storage":

Allow — one-time access, prompted again next time
Always Allow — permanent, no future prompts (convenient but any process running as your user can extract credentials silently)
Deny — blocks access, slk cannot authenticate

Token cache:

~/.local/slk/token-cache.json

— auto-validated, auto-refreshed on

invalid_auth

If auth fails (token rotated, Slack logged out):

rm ~/.local/slk/token-cache.json
slk auth

Slack desktop app must be installed and logged in. Does not need to be running if token is cached.

Reading Threads

Threads require a Slack timestamp. Use

--ts

to get it, then read the thread:

slk read general 10 --ts
# Output: [1/30/2026, 11:41 AM ts:1769753479.788949] User [3 replies]: ...
slk thread general 1769753479.788949

Agent Workflow Examples

Heartbeat/cron unread check —
```
slk unread
```
→
```
slk read <channel>
```
for channels that need attention
Save & pick up — Human saves threads in Slack ("Save for later"). Agent runs
```
slk saved
```
during heartbeat, reads full threads with
```
slk thread
```
, summarizes or extracts action items
Daily channel digest —
```
slk read <channel> 100
```
across key channels → compile decisions, open questions, action items →
```
slk send daily-digest "📋 ..."
```
Weekly DM summary —
```
slk read @boss 200 --from 2026-02-01 --threads
```
→ extract action items, decisions, context
Thread monitoring — Watch specific threads for new replies (incidents, PR reviews, decisions)
Draft for human review —
```
slk draft <channel> "..."
```
posts to Slack's editor UI for human to review before sending
Search-driven context —
```
slk search "deployment process"
```
or
```
slk pins <channel>
```
to pull context before answering questions

Limitations

macOS only — uses Keychain + Electron storage paths
Session-based — acts as your user, not a bot. Be mindful of what you send
Draft drop may fail with
```
draft_has_conflict
```
if Slack has that conversation open
Session token expires on logout — keep Slack app running or rely on cached token
