From 3b9e555560c22e8219d5cdfb40e5736a89fd29d4 Mon Sep 17 00:00:00 2001 From: Adam Moussa Date: Wed, 8 Jul 2026 16:46:42 -0400 Subject: [PATCH] feat(slack): include channel context in Slack prompts Re-land upstream #1633 onto the modular structure. Fetch cached Slack channel metadata once per event (_get_slack_channel_context) and thread it through the docs-plz gate, repo resolution, and process_slack_mention so prompts carry the channel name and a clearly-marked untrusted channel description. Avoids duplicate conversations.info calls.
