Behavior

1. Check for Pending Checkpoint

2. Capture Feedback

Accept feedback as argument or prompt interactively:

code

HITL Checkpoint: pre_credentials

Description: Add API keys and secrets before infrastructure deployment

Required Setup:
- Add AWS_ACCESS_KEY_ID to .env
- Add AWS_SECRET_ACCESS_KEY to .env
- Configure SLACK_WEBHOOK_URL (optional)

Enter your feedback or instructions for the next session:
> I've added AWS credentials. Skip Slack for now, we'll add it later.
  Also, use us-west-2 region instead of us-east-1.

3. Write Feedback to HITL_FEEDBACK.md

Create/update .frink/HITL_FEEDBACK.md:

markdown

# HITL Feedback

## Checkpoint: pre_credentials
**Amended at:** 2026-01-22 11:15:00 AM

### User Feedback
I've added AWS credentials. Skip Slack for now, we'll add it later.
Also, use us-west-2 region instead of us-east-1.

### Instructions for Next Session
- AWS credentials are now available in environment
- Skip Slack webhook configuration
- Use AWS region: us-west-2 (not us-east-1)

4. Log Amendment Decision

Write to .frink/checkpoint-history.json:

json

{
  "checkpoints": [
    {
      "id": "pre_credentials",
      "status": "amended",
      "amended_at": "2026-01-22T11:15:00Z",
      "feedback": "I've added AWS credentials. Skip Slack for now...",
      "feedback_file": ".frink/HITL_FEEDBACK.md"
    }
  ]
}

5. Resume Execution with Context

code

Checkpoint AMENDED: pre_credentials

Feedback saved to: .frink/HITL_FEEDBACK.md

The next executor session will receive this feedback
as additional context for implementing upcoming tasks.

Resuming execution...
Next Task: 4.1 Create DynamoDB table definitions

Run `/professor-frink:status` to monitor progress.

Feedback Integration

The feedback is loaded into the next executor session:

markdown

# Task Context: 4.1 Create DynamoDB table definitions

## HITL Feedback (from checkpoint: pre_credentials)
- AWS credentials are now available in environment
- Skip Slack webhook configuration
- Use AWS region: us-west-2 (not us-east-1)

## Task Details

This ensures human guidance is incorporated into the execution flow.
