File contents

Slack Thread Reader

Script for fetching Slack channel history and thread replies.

Script Location

scripts/slack-thread.sh (entry point) → scripts/slack-thread.py (main logic)

Usage

Read Thread

scripts/slack-thread.sh https://your-workspace.slack.com/archives/CHANNEL/pTIMESTAMP
scripts/slack-thread.sh <channel-id> <thread-ts>

Read Channel History

scripts/slack-thread.sh https://your-workspace.slack.com/archives/CHANNEL
scripts/slack-thread.sh <channel-id>
scripts/slack-thread.sh <channel-id> --limit 30

Channel History with Thread Replies (Full)

scripts/slack-thread.sh <channel-id> --with-threads

Limit Thread Replies (Optional)

scripts/slack-thread.sh <channel-id> --with-threads --thread-limit 5

Workflow

When given a Slack link or channel ID, use this script to fetch the conversation history.
⚠️ If the link type and the user's request don't match, always ask for clarification.
- Link format: /archives/CHANNEL = channel, /archives/CHANNEL/pTIMESTAMP = thread
- Example: If the user provides a thread link but says "get the channel history" → "The link you provided points to a specific thread. Did you want the thread content or the entire channel history?"
- People make mistakes. If the link and the request don't match, ask instead of guessing.
When asked to summarize channel history: Ask the user "Should I include thread replies?" and set the --with-threads flag accordingly.
Summarize or pass through the fetched content as-is.

Options

Option	Description	Default
`--limit N`	Number of channel history messages	50
`--with-threads`	Include thread replies inline	off
`--thread-limit N`	Max replies per thread (0=all)	0 (all)

Output Elements

Element	Format	Example
Timestamp	ISO 8601 (seconds)	`[2026-02-11T17:45:56]`
Sender	Real name	`John Doe:`
Mentions	`@name` resolved	`@Jane Smith`
Emoji reactions	Emoji + reactor names	`[:thumbsup: John,Jane]`
Attachments	📎 filename (type)	`📎 image.png (image/png)`
Thread reply count	💬N	`💬13`
Thread replies (inline)	├ └ tree	with `--with-threads`

Notes

The bot must be a member of the target channel. If you get a channel_not_found error, instruct the user to run /invite @botname in the channel.
Without --with-threads, channel history won't include thread conversations. Always confirm whether to include threads when summarizing.
