## Reflections & Logic

### 1. Browser Reliability Issues
**Problem:** Browser tool sering gagal — Google/Bing/Yandex kena CAPTCHA, DuckDuckGo connection refused, kadang Chrome CDP endpoint timeout.
**Workaround:** Gunakan `tavily_search` untuk riset, dan hindari browser bila tidak esensial.
**Future:** Selalu cek apakah browser bisa start dulu (`browser_use action=start`), dan siapkan fallback ke tavily.

### 2. DOCX Generation Pitfalls
**Problem:** Generate DOCX via Node.js (`docx` npm package) rawan syntax error:
- **Smart quotes** (`"..."`) dalam string JS menyebabkan parse error → selalu pakai single quote atau escape
- **Missing parameter** `cell(text, width)` — width harus selalu ada
- **Extra closing brackets** `])])` — perhatikan struktur `new TableRow({ children: [...] })`
**Pattern:** Validasi dengan `node script.js` dulu, lalu fix error per error. Gunakan `edit_file` untuk perbaikan kecil, atau rewrite section yang bermasalah.

### 3. File Operation Best Practices
**Problem:** `write_file()` requires BOTH `file_path` and `content` — mudah lupa parameter `file_path`.
**Fix:** Always double-check required parameters before calling.

### 4. Competitive Analysis Framework (for future similar tasks)
When analyzing competitors for Meta Ads:
1. Cari di Meta Ads Library: `facebook.com/ads/library/?active_status=all&ad_type=all&country=ID&q=KEYWORD`
2. Catat: website, positioning, bahasa, USP, pricing, services, kontak WA
3. SWOT analysis per competitor
4. Bandingkan dengan client: gap apa yang bisa diisi?
5. Beri rekomendasi strategi funnel: TOFU (awareness) → MOFU (consideration) → BOFU (conversion) + closing (WA/website)

### 5. Multi-Market Ad Strategy Framework
When targeting multiple countries:
- Split budget by market size (AU 60% / NL 40%)
- Adapt language: AU = English casual ("mate", "no worries"), NL = dual Dutch+English
- Different hooks: AU = proximity + value ("cheap flight"), NL = history + culture
- Create separate ad sets per country, different creative per market

### 6. User Communication Style
- Mas Eko casual, suka singkatan ("dgn", "yg", "udh")
- Appreciates detailed comparison tables
- Wants deliverables in DOCX format
- Likes concrete numbers (budget, estimates)
- Asks for "closing" direction — meaning where ads should direct users (WA, website, landing page)

### 7. File Merging is DANGEROUS — Prefer Chunking
**Problem:** Mencoba menggabungkan 3 file JS hasil truncation (`build_final_proposal.js` + `build_final_part2.js` + `build_final_part3.js`). Menghabiskan ~20 iterasi debugging tanpa hasil.
**Root Causes:**
- `write_file` truncates at ~27KB — file besar terpotong di tengah function call
- Saat merge, function `makeTableFull(` terpotong → headers hilang, rows menjadi orphan
- Comment blocks (`// PART 2 — continuation...`) terselip di antara arguments function call
- Nested double quotes (`"No hidden fees"` di dalam string JS) menyebabkan parse error
- Shell heredoc `<<` gagal bila Python mengandung `(` atau metacharacters
**Lesson:** JANGAN PERNAH merge file hasil truncation. Selalu rebuild dari nol dengan pendekatan chunking: tulis 6+ file JS kecil (masing-masing <15KB), lalu `cat chunk*.js > final.js`.

### 8. Chunking Strategy for Large JS Files
**Pattern that works:**
1. `chunk0.js` — semua helper functions (C, HC, BC, GC, sp, H1, H2, H3, P, BL, makeTable, dll)
2. `chunk1.js` — `new Document({...})` + styles + numbering + cover page + TOC + section 1
3. `chunk2–chunk5` — masing-masing 1-2 section konten
4. `chunkN.js` — `]);` (tutup sections array + Document constructor) + `Packer.toBuffer(doc).then(...)`
5. Concat: `cat chunk*.js > build_final.js && node build_final.js`
**Prinsip:** Setiap chunk tidak harus standalone valid — hanya pastikan tidak ada syntax error di dalam chunk itu sendiri. Gunakan single quotes (`'`) untuk menghindari konflik dengan double quotes di konten teks.

### 9. Nesting Quote Strategy for JS Code Generation
**Best practice:** Gunakan single quotes sebagai delimiter string JS, dan double quotes di dalam konten teks:
```js
P([new TextRun({text:'Competitive pricing: "No hidden fees" jadi angle utama'})])
```
Bukan:
```js
P([new TextRun({text:"Competitive pricing: \"No hidden fees\" jadi angle utama"})])
```
Ini menghilangkan kebutuhan escape quotes sepenuhnya.
