Iteration 2 – Prompt Log

Selected prompt log for the AI Collaboration Report – Iteration 2 (2026-10-07 ~ 2026-10-20). Dates and times are KST.

  • Entries cover Hyeon U Jeong's login/onboarding and Dongkun Moon's outfit recommendation contributions. Other members can add their own sections using the same structure.
  • Korean prompts are edited summaries of actual messages: spelling, informal wording and long attachments are normalized or shortened while preserving the technical intent. They are not verbatim transcripts.
  • Outcomes are retrospective summaries. A cited commit can include corrections made in subsequent turns.
  • Omitted: one-word confirmations, routine commit/push commands, account/credential values, personal file paths, unlock replies, general concept questions and drafts of team-chat messages.

Hyeon U Jeong — Codex (OpenAI), login and onboarding

The following 16 selected entries focus on requirements, implementation and real-device feedback. Entry IDs retain their original numbering after selection. Times are taken from the original session record; all dates are in 2026. Codex had repository/terminal access and could operate the connected Android app. I supplied product decisions and device feedback, approved the visual direction, and decided when work could be published.

Planning and schema

ID Date · KST Prompt Outcome
L01 10-14 11:48 소셜 로그인 없이 회원가입·기존 계정 로그인을 제공하고, 사용자 정보는 최소한으로 수집해주세요. 가능하면 앱을 다시 열어도 로그인 상태를 유지하도록 해주세요. Set the initial scope. Later design used app-specific ID/password accounts and a fixed 30-day session; this message did not itself implement authentication.
L02 10-16 02:58 마이프로필에서 로그인 버튼을 누르면 아이디·비밀번호·로그인 버튼이 있는 창을 열고 회원가입 링크를 제공해주세요. 비로그인은 안내문을 표시하고 로컬에 저장하게 해주세요. Defined the guest/account entry flow and local-only guest persistence. Recovery/social login and extra required personal information were excluded in the following clarification.
L04 10-16 03:08 기존 로컬 저장과 신규 DB가 충돌하면 신규 구현을 우선해주세요. 기존 DB 호환성만을 위해 불필요한 파일이나 이중 저장 구조를 추가하지 마세요. Recorded the priority in feature instructions; the resulting guest/account snapshot store did not introduce a parallel legacy compatibility store.
L06 10-16 03:17 기존 데이터는 보존할 필요가 없습니다. 로컬 데이터를 가져오고, 계정과 겹치면 교체 여부를 확인하도록 해주세요. Authorized the transition cleanup and conflict-review direction. The implementation removes legacy unowned rows during migration; this is not a policy to delete newly created user data.

Onboarding scope and style profile

ID Date · KST Prompt Outcome
L07 10-16 03:23 참고 화면처럼 8페이지 온보딩을 로컬 저장에 연결하고 로그인은 사용자가 원할 때 하도록 해주세요. 마이프로필에는 스타일 프로필을 표시하고 체형 분석은 버튼을 눌러 별도 화면에서 보게 해주세요. Added optional onboarding to this feature's scope and separated its completion/style data from the existence of body measurements. It was implemented later in ea4bbb4.
L08 10-16 03:26 자주 입는 컬러는 처음에 비워두고 사용자가 저장한 값만 DB에 저장해주세요. 체형 정보는 체형 밸런스 참고에서 열도록 해주세요. Confirmed empty initial colors and the body-details entry. No sample colors or wardrobe-derived palette were prefilled.

Authentication and local persistence

ID Date · KST Prompt Outcome
L10 10-16 04:10 입력 검증과 로그인 시도 제한을 추가해주세요. 5회 이상 실패하거나 짧은 시간에 반복할 때 제한하고, 프로필 요청의 입력 가짓수도 제한해주세요. Implemented five failures in five minutes → five-minute ID lock, shared authentication IP limits, bounded JSON and allowed profile values; 81ca2f5.
L12 10-16 04:44 연결한 폰에서 확인할 수 있도록 서버와 DB를 실행하고 로컬 테스트 데이터를 넣어주세요. Applied the local setup and populated disposable sample data for phone verification. These test records were not committed as application data.
L15 10-16 05:25 비밀번호 확인 오류를 고친 뒤 가입하면 로그인 응답을 읽지 못한다고 나옵니다. 다시 가입하면 이미 존재하는 아이디라고 하고 로그인도 되지 않습니다. 원인을 확인하고 수정해주세요. Reproduced successful account creation followed by an app parsing failure. Replaced the expiry parser with offset-aware parsing and added real-response-format regression checks; 7715550.

Manual imports and profile interaction

ID Date · KST Prompt Outcome
L17 10-16 06:20 로그인할 때 가져오기 창을 자동으로 띄우지 말고, 로그인한 뒤 사용자가 필요할 때 직접 눌러 가져오도록 바꿔주세요. Changed the trigger to a separate manual action. Account data loads on login; guest upload waits for explicit consent.
L18 10-16 06:26 가져오기 아이콘을 로그아웃 아래에 두고, 누르면 개수와 취소·가져오기가 있는 팝업을 표시해주세요. 핏·무드·컬러의 중복 취소 버튼도 정리해주세요. Added the count/consent interaction and simplified editor controls. The requested icon placement was subsequently moved beside the My Profile title.

Eight-step onboarding and phone feedback

ID Date · KST Prompt Outcome
L21 10-16 07:24 테스트 사진을 갤러리에 넣은 뒤, 현재 연결된 테스트 DB와 앱을 초기화해서 온보딩부터 확인할 수 있게 해주세요. Prepared a first-run device test with explicit reset authorization. This did not authorize automatic deletion of later production user data.
L22 10-16 07:29 Step 1은 시작하기 위·로그인 아래로 배치해주세요. Step 2는 처음부터 레귤러를 강제 선택하지 말고 자유롭게 선택하게 하되, 아무것도 고르지 않고 다음을 누르면 레귤러를 적용해주세요. 이번 작업 부분의 폰트와 디자인도 시안에 맞춰주세요. Persisted an empty fit draft, applied regular on continue, and aligned selection marks, typography and the bold StyleMate login wordmark; ea4bbb4.

Step 6 layout feedback

ID Date · KST Prompt Outcome
L26 10-16 09:01 Step 6 옷장 등록 현황의 진행바를 제거해주세요. 서버 연결과 측정점 서버 오류도 확인해주세요. Distinguished the extra wardrobe progress bar from the shared step indicator. Investigated local USB/server connectivity; the count-layout correction followed in L27–L28, without redesigning landmark inference.
L27 10-16 09:10 내 옷장 전체 개수 제목을 없애고 상의·하의·신발의 현재 개수와 목표를 한 줄에 보여주세요. Removed the total-count heading and retained category-level counts; the visual separator/width feedback followed in L28.
L28 10-16 09:13 구분자는 문자로 넣지 말고 시각적인 선으로 표시하며, 세 항목이 가로 화면을 넓게 사용하도록 해주세요. Used equal-width columns and actual vertical dividers. Updated the existing onboarding assertions and checked the final phone layout; 490fcab.

Dongkun Moon — Claude Code (Claude Opus 5.5), outfit recommendation (P20, P21)

The 48 entries below cover the recommendation work, the real-phone test for the demo video and the documentation. The groundwork on 10-07 and 10-08 is included because it fed directly into P20 and is not part of the Iteration 1 report. Claude Code worked in the local repository: it could read and edit files, run tests and scripts, build the app, and drive the emulator and my phone over USB. It drafted every issue and PR, and I read each one before it was posted.

Note: Each row matches one prompt I sent at that time; the request and the outcome are unchanged. Also omitted: questions about the schedule sheet and the midterm slides, and the API key I configured.

Groundwork (10-07 – 10-08, before Iteration 2)

ID Date · KST Prompt Outcome
R01 10-07 17:12 "Propose a database schema for the app. Start from the existing table and add what the coming features (body profile, outfits) need. Treat it as a proposal for the team; do not change any code." Proposal for user, garment and outfit tables, with the gaps to close first (e.g. garments had no owner). No code changed.
R02 10-07 18:48 "Context: the team may not build the chat feature. Task: (1) review the whole develop branch; (2) using our body analysis model, work out how the app should recommend clothes for a given body, and look for related models." Review of develop; body-profile fixes on a local branch (profile kept on the device, crash and upload fixes), later shipped in PR #25 as 6d2924a
R03 10-07 19:28 "Undo the change that maps the preferred styles and fit to the wardrobe's codes; I have a different approach in mind. Keep the other fixes." Reverted; the other three fixes stayed
R04 10-08 00:27 "Context: the inputs are the user's body measurements, fit preference (regular, slim, …) and the clothes they own; the K-Fashion dataset (AI Hub) will be the garment database. Task: decide what criteria each garment should be scored on, and find out whether a model that produces such scores already exists." No public model covers body, fit, wardrobe and season together (OutfitTransformer and ViBA-Net reviewed); plan to combine rules with compatibility learned from K-Fashion outfits
R05 10-08 01:06 "Here are the downloaded K-Fashion files. Inspect all of them and report what we can use." 1,088,781 photos and 1.73 M labelled garments; about 580,000 outfits with two or more garments; almost no men's clothing
R06 10-08 01:37 "Show one example of the final recommendation screen a user would see." A home-tab mock-up ("오늘의 코디") with real K-Fashion garments, scores and reasons
R07 10-08 02:02 "Now solve these problems yourself and build one local test page to try the solution." Local engine and test page on K-Fashion data: cut-out cleaning, de-duplication, PMI compatibility (FITB 44 %, chance 25 %), size advice from fit labels, weather rules; kept out of git

Recommendation design (10-10 – 10-12)

ID Date · KST Prompt Outcome
R08 10-10 23:49 "Context: [생략: TA notice — gemini-3.5-flash allows 5 requests per minute and 20 per day on the free plan; use a flash-lite model]. Task: tell me what we need to change." Nothing to change: chat parsing already used gemini-3.1-flash-lite; image generation (try-on) has no free quota at all
R09 10-10 23:52 "When I give feedback in the test page's chat, do the garment scores change in real time?" Taste weights change at once; scores are recomputed on the next request
R10 10-11 00:53 "Context: a teammate shared a Jev demo (choosing clothes from a user's wardrobe and virtual try-on); another proposed a masked-token model over the K-Fashion labels [생략: preprocessing proposal]; I suggest rules for body shape, outfit compatibility, real-time weather and colour. Task: first research Jev and use as much of its approach as possible; then combine these ideas into a local test page and explain the method. Also suggest anything we have not considered." /stylist test page with Jev-style per-slot decisions, 45 body-shape rules with sources, live weather, and the teammate's masked transformer trained on 352,673 outfits (FITB: PMI 44.8 %, masked 45.4 %, both 50.1 %)
R11 10-12 14:14 "How does Jev's algorithm work?" Public facts separated from guesses: a decision-only model with calibrated probabilities over fixed options; the architecture is not published
R12 10-12 15:59 "Explain how the garment labels were preprocessed into tokens." Seven-step explanation: cleaning, de-duplication, season token, tokens, vocabulary, masking
R13 10-12 16:02 "Export the JSON right after preprocessing." export_preprocessed.py: a step-by-step sample and the full train/val files (352,673 / 95,070 outfits), kept outside git
R14 10-12 16:11 "Explain how the chat feature's prompt to Gemini works." Gemini only turns a message into structured taste events (JSON schema); our engine does the scoring
R15 10-12 16:42 "List the outfit rules we currently apply (colour, design, …)." Rules for colour harmony, learned co-occurrence, body shape, fit and weather

Integration into the app (P20, P21)

ID Date · KST Prompt Outcome
R16 10-12 16:49 "Context: Iteration 2 has started (PM: Kihwan; Hyeon U: login and onboarding; me: the recommendation system and retraining on outfits that have both a top and a bottom; Juhyeon: chat). Database: a user table for the body profile; a clothes table whose fit is computed from the garment's measurements and the user's body and can be corrected before saving; an outfit table, schema up to you. Task: move the model from our test server into the app on a new branch. Constraints: K-Fashion is training data only; recommendations come from the garments the user has registered; label each new garment from its measurements and the body profile and let the user review the labels before saving; reuse Hyeon U's registration screen; follow the attached mock-up's style; leave chat out (Juhyeon builds it on a separate page)." Branch with 5 commits: garment labels, outfit tables and API, home "오늘의 코디" and 코디북, retraining comparison (48.5 % vs 48.8 %, existing model kept), docs
R17 10-12 22:04 "Correction: recommending from the user's own wardrobe was always the goal; I had misread it. Recommending outside garments is a later, optional feature. Update only the issue text. Question: does Hyeon U's garment-measurement flow need changes too? Which attributes (colour, design, style, …) should be checked when the photo is taken?" Issue text corrected; the measurement points need no change; list of attributes and where each can come from
R18 10-12 23:05 "Must the user enter all of these attributes by hand, or can we detect them when the photo is taken?" Most can come from the same Gemini call, but the back photo hides necklines, prints and details; blend, thickness and stretch cannot be seen
R19 10-12 23:14 "How far has Hyeon U implemented the wardrobe?" Summary of the merged wardrobe flow (AR capture, HRNet points, Gemini name/category/colour, editor) and what is missing
R20 10-12 23:28 "Context: [생략: my two proposals to Hyeon U about the duplicated fit field and the AR garment type]. Explain what they mean; I don't follow them." Two fit controls could show different values; the AR garment type was discarded after measuring
R21 10-12 23:33 "Implement now and tell Hyeon U afterwards: (1) add a front photo; (2) let the same Gemini call suggest the subcategory, styles and details; (3) merge the two fit controls into one; (4) pass on the garment type chosen during AR capture instead of discarding it; (5) finally, verify the whole app for errors." After three clarifying questions: front photo for tops and outerwear, Gemini suggestions incl. visible materials, one fit control, AR type passed on (eefd936, 3982c35); 135 pytest, 54 Django, 60 Android unit and 23 UI tests passed
R22 10-13 00:39 "Create the issue, push the branch and open the PR as drafted." Issue #24, PR #25
R23 10-13 00:52 "Check the CI results and fix any failure." All three CI jobs passed
R24 10-13 00:58 "Context: [생략: Iteration 2 schedule]; P20 and P21 are my tasks. Task: align the issue and the PR with them." Titles and sections split into P20 and P21, following the team's P-number format
R25 10-13 03:33 "Context: Hyeon U replied [생략: keep the front photo, skip care-label photos; are terms such as X스트랩 and 니트꽈베기 K-Fashion labels?]. Task: suggest an answer and anything we should change." Both terms are K-Fashion labels (278 and 3,721 uses); found the 하운즈 투스 no-break-space mismatch; suggested display names
R26 10-13 03:38 "Check whether Hyeon U has already pushed fixes on GitHub." He had: 28942eb fixed five label/model mismatches, and PR #25 was merged into develop
R27 10-13 03:40 "Skip the display names; close issue #24 and update my local branch." Issue #24 closed; local develop at b3acbc5

Men's training data (10-13)

ID Date · KST Prompt Outcome
R28 10-13 03:44 "Context: our model is trained only on women's clothing. Task: as a separate test, check whether men's clothing can be learned from labelled data in the same way. First check whether crawling, preprocessing and labelling Musinsa data is feasible; if not, find another source of men's clothing data our model can learn from." Musinsa ruled out (robots.txt blocks crawlers; terms and database rights). AI Hub "연도별 패션 선호도" (40,868 men's photos) chosen, with Gemini labelling checked against K-Fashion labels first. Scripts kept outside git; waiting for the AI Hub application

Real-phone test for the demo video (10-17)

ID Date · KST Prompt Outcome
R29 10-17 16:40 "I want to test the current GitHub repository locally to record a demo video. How do I do this?" Setup steps; the missing database and Gemini key identified
R30 10-17 16:41 "Set up the local SQLite settings, start the backend and the emulator, and install the app." Backend on an empty SQLite database (settings outside the repo); app installed on the emulator
R31 10-17 16:58 "Tell me which photos and values to enter at each step of the demo." Inputs per screen; AR capture needs a real phone
R32 10-17 17:04 "I will register clothes on my real phone; connect the phone to the server instead." Galaxy S22 connected over USB, latest debug build installed
R33 10-17 17:05 "Context: Kihwan asks whether guest and login code are mixed, with one extra API each, and plans to delete the guest APIs before deploying. Task: check the code." Both paths were intended in PR #26; the app called the guest APIs before login
R34 10-17 17:08 "What should I enter for weight?" Leave it empty: the synthetic demo bodies have no true weight (correcting its earlier "55 kg" suggestion)
R35 10-17 17:14 "Garment analysis takes too long; find out why." HRNet model missing locally (it is created at Docker build); Gemini taking 11–30 s or timing out
R36 10-17 17:48 "Install the HRNet model and restart the server; increase the Gemini timeout." Model installed (1.4 s per image); timeout 30 → 40 s in local settings only
R37 10-17 17:57 "Analysis keeps failing; what is the problem?" Gemini "high demand" (503) and timeouts; app, server, key and connection fine
R38 10-17 18:06 "Switch only the local dev settings to gemini-3.5-flash-lite and restart the server." 1.6 s per analysis; team code unchanged
R39 10-17 18:07 "Can garments be analysed without the Gemini key, using only our local code?" Three options (rule-based, CLIP, trained classifier) with their effort; Gemini kept for now
R40 10-17 18:09 "Only the shoulder width is filled in automatically and I type the rest. Is that expected?" No: the phone had not reached the server during those captures; HRNet fills a measurement only when all its points are confident
R41 10-17 18:14 "I added a garment with 촬영하기. Check the server log and the points HRNet found." Automatic measurement worked; one value (cuff 81 cm) flagged as wrong
R42 10-17 18:15 "Create test pictures for my wardrobe that look like what I captured, as many garments as possible, and put them in my phone's gallery as well." 50 test garment photos added to the phone's gallery (local only)
R43 10-17 20:42 "I don't see the clothes in my 옷장." The photos had only been copied to the gallery; 49 garments then registered through the API (51 in total)
R44 10-17 21:24 "Is the app still analysing the clothes? I see none." The server had stopped and the USB link had reset; both restored

Documentation (10-19 – 10-20)

ID Date · KST Prompt Outcome
R45 10-19 15:59 "Context: [생략: course guidelines, lecture notes, our iteration folders and the team chat export]. Task: organise this material for the project, then compare it with the repository and list what is still missing for Iteration 2." Status review; the Requirements and Design pages were then updated (Requirements 0.5–0.6, Design 0.4–0.5)
R46 10-20 13:16 "Why do we need to back-merge main into develop? Did you check what the team agreed in our chat?" It had relied on a note an earlier session wrote, not on a team decision; the proposal was dropped
R47 10-20 13:20 "Is PR #27 what you are describing? That is my teammate's work, not mine; do not change anything there." Confirmed PR #27 is Kihwan's; nothing of his was changed
R48 10-20 13:30 "[생략: the agent's note that the §6.4 wireframes still show the earlier optional-login flow] What is the problem with this?" Four mismatches with the current flow; the §6.4 caption corrected
