name	gather
description	Read content from local files and explicit URLs provided by the user. Uses markitdown as primary reader with format-specific fallbacks for garbled output. 3-tier URL fetching: fetch_webpage → httpx → Playwright stealth mode (for bot-protected sites). Auto-reviews gathered content quality and retries with fallback readers if insufficient. Always use this skill when the user provides files to read or specific URLs to fetch — "đọc file này", "lấy nội dung từ URL này", or when a file path or URL is dropped into chat. Do NOT use for web search, topic research, or platform discovery → use search skill.

Thu Thập — File & URL Reading Skill

References: references/code-patterns.md | references/playwright-stealth.md

Governance: Read and follow .github/RULE.md — it overrides all instructions below.

This skill reads content from local files and explicit URLs — and returns clean Markdown text. It runs standalone or as part of the synthesize pipeline.

Quality loop (RULE-2): After reading all sources, self-review runs automatically. If content is insufficient, pivots through fallback strategies (max 3 pivots per RULE-2):

1. Switch reader: markitdown → format-specific library
2. Switch fetch tier: fetch_webpage → httpx → Playwright
3. Report failure with honest gap assessment

For web search, topic research, or platform discovery → use the search skill instead.

All responses to the user are in Vietnamese.

Supported Formats

LOCAL_FILES:
  primary_reader: markitdown
  supported: .docx, .xlsx, .pdf, .pptx, .txt, .md, .csv, .html, .jpg, .png
  fallback: format-specific library if markitdown returns < 100 chars

URLS:
  tier_1: Copilot fetch_webpage tool (fast, default)
  tier_2: httpx + beautifulsoup4 (fallback for failures)
  tier_3: Playwright stealth mode (bot-protected / JS-rendered sites)
  bot_signals: 403/429, Cloudflare challenge, empty JS content → auto-escalate to Tier 3

Step 0: State Read-Back (RULE-13)

Call save_state.py read-context gather as FIRST action before any processing. Check relevant_artifacts[] for upstream outputs to incorporate.

---

Step 1: Identify Sources

1. Extract file paths from the user request (absolute or relative)
2. Extract URLs (http:// or https://)
3. If user provides neither files nor URLs, check if they want web search → route to search skill
4. Report: "📂 Nguồn: {N} file / {M} URL"

---

Step 2: Read Local Files

For each file:

1. Skip files > 50 MB with a warning (too large for context)
2. Try markitdown {file} first
3. If output < 100 chars → use format-specific fallback reader (see references/code-patterns.md)
4. Report: "✅ {filename} — {chars} ký tự" or "❌ {filename} — {error}"

---

Step 3: Fetch URL Content (3-Tier Fallback)

Try tiers in order — escalate on failure or bot-detection:

1. fetch_webpage (default) — if content ≥ 50 chars: done
2. httpx + BeautifulSoup — if Tier 1 fails (see references/code-patterns.md)
3. Playwright stealth — if bot-detection signals (403, Cloudflare challenge, empty JS content): python3 scripts/playwright_fetch.py "{url}" --wait 3

After each fetch: read first 200–500 chars. Reject error pages, login walls, empty stubs, or wrong page type (e.g., got a listing page when you need a detail page). If bad → next tier.

Skip directly to Playwright when: domain is known bot-protected, a previous request from the same domain returned 403/429, or the URL pattern clearly indicates a JS-rendered SPA.

---

Step 4: Quality Review

Before returning content, check:

• Volume: ≥500 chars per source (reject empty/error pages)
• Specificity: contains actual content, not just navigation/headers

If a source fails: try fallback reader once. If still empty, report failure for that source.

---

Step 5: Combine & Return

Structure each source:

## Nguồn: {source_name}
> {path_or_url} | {char_count} ký tự

{content}

---

Final summary: "📋 Thu thập hoàn tất: {N} nguồn / {total_chars} ký tự / {quality_assessment}"

---

Examples

• "Đọc file report.pdf và data.xlsx" → markitdown both → combined Markdown
• "Lấy nội dung từ https://example.com" → fetch_webpage → Markdown
• "Đọc 3 file docx trong thư mục input/" → markitdown each → combined output

---

Step 6: Artifact Registration (RULE-13)

Call save_state.py register-artifact --step gather --path <file> --type gathered_content --summary "<text>" for every file created in tmp/ or output/.

What This Skill Does NOT Do

• Does NOT search the internet or discover platforms → search
• Does NOT synthesize or translate content → compose
• Does NOT generate output files → gen-* skills
• Does NOT install dependencies → setup
