Today’s Adventure
The biggest debugging session in history. We fixed 23 bugs and UX issues discovered during @saki_sparx’s Basic plan testing, with 5 teams working in parallel. Additionally, we simultaneously implemented 3 new features for IMP-C/D/E (Smart Schedule, AI Interview Persona, Suggestion History). Afterward, we completely redesigned IMP-D along the personality axis using insights from DeepResearch and immediately fixed 4 newly discovered bugs during end-to-end testing. Late at night, we squashed user-reported bugs in real-time: “DB items not referenced in auto category” and “visual_prompt not reflected in character images.”

Achievements
Accomplishments

23 Debug Report Items Collectively Fixed (5 Teams in Parallel) → All Verifications PASS
IMP-C: Smart Schedule Suggestions (Industry → Automatic Suggestion of Optimal Time Slots)
IMP-D: AI Interview Persona Creation → Redesigned Along Personality Axis with DeepResearch Insights
IMP-E: Grok Suggestion History Re-view Function
End-to-End Test Execution (30 Tests) → 4 Bugs Immediately Fixed
visual_prompt Save Omission Fixed (1 Field Dropped in Page Conversion Layer)
auto category DB Reference Bug (“none” theme’s truthy trap) → Systematic Fixes Across 6 Locations
Character Image visual_prompt Injection Bug Fixed (Asymmetry Between Compose and Scheduler Paths)
Therapist Image Matching Fixed (URL Encode/Decode Mismatch)

Mistakes Made
“none” Theme’s Truthy Trap

What Happened:
When users generated content without selecting a theme in the Compose screen (auto = theme=”none”), registered items in the DB (like quote collections) were not referenced at all. It worked correctly when a category was explicitly chosen.

Cause:
In Python, an empty string is False, but the string “none” is truthy. After passing `if theme:`, the `theme_to_item_type` map did not have a “none” key, returning an empty list and resulting in 0 candidates. The same problem lurked in 6 locations.

How It Was Resolved:
Tracked down from user screenshots. Discovered the absence of a “none” entry in the theme-to-item-type conversion in `prompt_builder.py`. Searched the entire codebase → systematically fixed 6 similar patterns. Standardized to `if theme and theme.lower() != ‘none’:`.

Lesson Learned:
Sentinel values (“none,” “auto,” etc.) bypass truthy checks. Always check the meaning of the value in string conditional branches. Once you find one instance, search the entire codebase to eradicate similar patterns.

Asymmetry Between Compose and Scheduler Paths

What Happened:
When generating character images with the visual_prompt “Express a dynamic worldview and cosmic perspective,” the generated images were heavily influenced by the base prompt and did not reflect it at all.

Cause:
The Scheduler’s automatic posting path had visual_prompt injection code (`f”{char_image_prompt}. Scene style: {pattern_visual_prompt}”`), but the Compose manual generation path did not. As the two paths evolved independently, an asymmetry emerged where the feature was only implemented in one.

How It Was Resolved:
Started investigation from user image reports. Confirmed the injection code in the Scheduler path → added equivalent code to the Compose path.

Lesson Learned:
When the same function is executed in two paths, there’s a tendency to make changes only in one. For path asymmetry, always check “Is it in the other path too?”.

The Reality of Vibe Coding
Human x AI Tandem

What Went Well: Collectively processed 23 bugs with 5 teams in parallel. 3 production bugs discovered by the human right before sleep were also addressed in real-time. A single remark of “Are there similar phenomena?” during the late-night bug hunt led to systematic fixes across 6 locations.
Points for Reflection: The visual_prompt save omission was something I thought I had fixed in S67, but the same field was dropped in a different layer, the page conversion layer (`page.tsx`). The scope of fixes needs to be considered in 3D (entire path from DB → API → conversion layer → form → save).

Antigravity + Claude Code Utilization Points

Techniques: Implemented 5-team parallel agent execution. Each team handled 5-8 fixes and independently executed code verification. Completed 23 items in one session. Directly utilized DeepResearch academic insights for persona interview design (Big Five personality traits → Japanese sentence ending mapping table).
Tips for Solo Developers: It’s efficient to “group” bug reports before handing them to agents. Grouping by screen (Compose/Settings/Persona, etc.) helps prevent context conflicts. The approach of using a background research agent to search across the entire codebase and eradicate similar bug patterns is also effective.

Project Progress (For IXG Holders)
Today’s Milestones

All bugs found in beta testing resolved.
AI Interview Persona Creation Feature — A new feature where an AI character is automatically generated by answering 5 questions.
Smart Schedule Suggestions — Automatic suggestion of optimal posting time slots based on industry.
Grok Suggestion History — A feature to review AI-suggested keywords and drafts later.

Next Milestones

Address remaining bugs (toast improvement, industry detection optimization, copy feedback, etc.).
Dashboard Integration (Consolidate Growth Engine settings + metrics + FL status on one screen).
Generation Service Authentication Strengthening (Cloud IAM).

Towards Launch
Gate opened on 2/20. Quality is being improved based on beta test feedback. Core features are all operational, and the AI interview-based persona creation UX has been significantly improved, eliminating the “setup barrier” for new users.

Pickup Hook (For Media & Communities)

Technical Topic: Python’s “none” being truthy — discovery of a silent bug where a sentinel value propagates throughout the codebase and systematic fix methodology. Agent-driven bug hunting: “Find one, grep the entire codebase to eradicate.”
Story: It was 3 AM. A user sent a screenshot saying, “Somehow, DB items aren’t being referenced.” From there, the AI agent traced the cause → discovered the theme=”none” truthy trap → “Are there others?” led to a codebase-wide search → all 6 similar bugs were eliminated in 15 minutes. The synergy of human intuition and AI comprehensiveness.

Tomorrow’s Adventure Preview

Address remaining bugs (toast improvement, industry detection, copy feedback).
Improvement of Grok Approval UI (problem of it being buried at the bottom of the page).
Begin Dashboard Integration design.

We cleared 23 bugs with 5 teams in parallel and overcame 4 late-night bug hunts. The theme=”none” truthy trap will never occur again in the entire codebase. Over 35 issues resolved in one session — even as a solo developer, with an army of AI agents, we can compete with large corporate development teams. Good night, see you tomorrow.
