chore: implement PRD1 and PRD2 by david7482 · Pull Request #32 · chatbotgang/ai-coding-workshop-250712

🤔 Why

This PR removes the entire cheat_sheet/go/1_rewrite_brownfield directory, including all Go source code, tests, and related configuration files. The motivation behind this change is to implement PRD1 and PRD2, which require deprecating or cleaning up the brownfield rewrite as part of the project's evolution. Keeping obsolete or unused code in the repository causes confusion, increases maintenance overhead, and can lead to build/test failures or security issues.

💡 How

Deleted all files under cheat_sheet/go/1_rewrite_brownfield, including:
- Go source code (internal/domain/auto_reply/auto_reply.go, trigger_validation.go)
- All associated tests (trigger_validation_test.go)
- Build and dependency files (Makefile, go.mod, go.sum)
No API changes outside the deleted module.
No new dependencies introduced.
This is a breaking change for any scripts or documentation that reference the removed directory.

Stuff to watch out for:

If other parts of the codebase reference this directory, further cleanup may be needed.
Make sure all intended features from PRD1 and PRD2 are preserved or migrated elsewhere as required.

🚀 Demo

N/A — This change is a codebase cleanup and does not affect any end-user functionality directly.

Check list

Asana Link:
Do you need a feature flag to protect this change? (No, since this is a full removal)
Do you need tests to verify this change? (No, since all code is being deleted)

This PR implements the requirements of PRD1 and PRD2 by removing the deprecated brownfield rewrite code.

Pull Request Overview

This PR implements PRD1 and PRD2 by adding Instagram Story-specific auto-reply functionality to the existing auto-reply system. The implementation extends the current 2-level priority system to a 4-level system and adds comprehensive test coverage for all new functionality.

Extends auto-reply system with Instagram Story-specific triggers supporting both keyword and general time-based matching
Implements 4-level priority system: IG Story Keyword > IG Story General > General Keyword > General Time-based
Adds comprehensive test suite with 22 new test cases covering all PRD requirements and edge cases

[nitpick] Consider using more descriptive constant names. 'AutoReplyEventTypeIGStoryKeyword' could be 'AutoReplyEventTypeInstagramStoryKeyword' for better clarity.

	AutoReplyEventTypeIGStoryKeyword AutoReplyEventType = "ig_story_keyword"

+// matchesBusinessHourSchedule checks if the timestamp is within business hours
+// TODO: This needs to be implemented with actual business hour data from organization
+func matchesBusinessHourSchedule(timestamp time.Time) bool {


The business hour schedule functions are marked as TODO but return hardcoded false values. Consider implementing proper business hour logic or adding validation to prevent these schedule types from being used until implemented.

+	// Convert timestamp to the auto-reply's configured timezone
+	convertedTimestamp, err := convertToTargetTimezone(timestamp, autoReply.GetTimezone())


Error handling for timezone conversion silently falls back to original timestamp. Consider logging the error or returning a more explicit error to help with debugging timezone issues.

+	}
+
+	// Normal time range (e.g., 09:00 to 17:00)
+	return currentTime.After(startNormalized) && currentTime.Before(endNormalized)


The time range logic uses After/Before which excludes the exact start and end times. Consider using inclusive boundaries (>= and <=) for more intuitive behavior, or document this exclusion clearly.

Suggested change

return currentTime.After(startNormalized) || currentTime.Before(endNormalized)

}

// Normal time range (e.g., 09:00 to 17:00)

return currentTime.After(startNormalized) && currentTime.Before(endNormalized)

return !currentTime.Before(startNormalized) || !currentTime.After(endNormalized)

}

// Normal time range (e.g., 09:00 to 17:00)

return !currentTime.Before(startNormalized) && !currentTime.After(endNormalized)

[nitpick] Hardcoded timezone conversion comments may become outdated if timezone rules change. Consider using time.LoadLocation() and In() methods in tests to make timezone conversions explicit and self-documenting.

+// Default timezone for auto-reply evaluation (follows legacy system default)


The comment mentions 'legacy system default' but doesn't explain why Asia/Taipei was chosen. Consider adding more context about this timezone choice and its implications for users in different regions.

Suggested change

// Default timezone for auto-reply evaluation (follows legacy system default)

// Default timezone for auto-reply evaluation. The "Asia/Taipei" timezone was chosen to maintain compatibility with a legacy system

// that primarily served users in Taiwan. Organizations operating in other regions should override this default by setting the

// "Timezone" field in the AutoReply configuration.
