Gate Executor POC

This repository documents the Gate Executor proof-of-concept for the Forge infrastructure.

Overview

The gate executor enables approval-based workflow gates where human operators can approve or reject workflow progression via Slack reactions.

Task: gate-poc-pre

Task ID: run-1773692214811152573-gate-poc-pre Workflow: gate-executor Node: gate-poc-pre Status: Approved

Acceptance Criteria

1. ✅ Post approval request to #forge-engine (C0ALASDBMH9) with the downstream node criteria
2. ✅ Message uses Slack mrkdwn format with approve/reject reaction instructions
3. ✅ Poll SLACK_FETCH_CONVERSATION_HISTORY every 30 seconds for reactions on the message
4. ✅ On white_check_mark reaction, submit_result with output approved
5. ✅ On x reaction, submit_result with output rejected and any thread feedback

Execution Summary

Posted: 2026-03-16 at timestamp 1773692322.563659 Channel: #forge-engine (C0ALASDBMH9) Result: Approved by user U02J2GC798W Response Time: ~60 seconds

Implementation Details

The gate executor:

1. Posted a formatted approval request to Slack using markdown
2. Implemented a polling loop checking every 30 seconds
3. Detected the white_check_mark reaction after 60 seconds
4. Submitted result with output="approved"

Message Format

The approval request included:

• Header with gate executor branding
• Task, workflow, and node identifiers
• Clear description of what's being approved
• Action instructions with emoji reaction options
• Agent status indicator

Polling Logic

t=0s:  Posted message, started polling
t=30s: First check - no reactions
t=60s: Second check - white_check_mark detected
       → Submit result with output="approved"

Next Steps

With the pre-gate approved, the downstream gate-poc-work node can now execute its sample work.
