+# Polymarket-Browse Skill Review
+
+**Date:** 2026-03-25  
+**Reviewer:** Hermes Agent (Shoko)  
+**Version Reviewed:** Current HEAD
+
+---
+
+## 1. Current State of SKILL.md
+
+### 1.1 Overview
+The SKILL.md is well-structured with clear sections:
+- Installation instructions (Hermes Agent + OpenClaw)
+- Usage with argument reference
+- Output format examples
+- Game categories table
+- Filters explanation
+- Pagination and rate limiting notes
+- Odds format documentation
+
+### 1.2 Strengths
+- Clear argument documentation with defaults
+- Good output format examples showing both match and non-match markets
+- Filters section is detailed and explains tradeable vs non-tradeable logic
+- Game categories table is easy to reference
+- Rate limiting and backoff strategy documented
+
+### 1.3 Issues/Gaps in SKILL.md
+
+| Issue | Severity | Notes |
+|-------|----------|-------|
+| No troubleshooting section | Low | API errors, partial fetches, common issues not documented |
+| No examples for --search | Low | Only mentioned in passing, no concrete example |
+| No mention of required dependencies | Low | Assumes curl is available (it is on Linux) |
+| No changelog | Low | Hard to track what changed between versions |
+| Telegram section minimal | Low | Doesn't explain HTML parse_mode limitations |
+| No credits/author info | Low | Who built this? |
+
+### 1.4 Recommendations for SKILL.md
+
+1. **Add troubleshooting section:**
+   - Partial fetch warnings (API errors/timeout)
+   - What to do if no markets appear
+   - Explaining why some matches disappear after they start
+
+2. **Add concrete usage examples:**
+   ```bash
+   # Example: Find FlyQuest Counter-Strike matches
+   polymarket-browse --category "Counter Strike" --search "FlyQuest"
+   
+   # Example: Get 10 matches, no tournament futures
+   polymarket-browse --category "Valorant" --matches 10 --non-matches-only
+   ```
+
+3. **Add HTML escape notes for Telegram:**
+   - `<` `>` `&` `>` `<` need to be escaped in Telegram messages
+
+---
+
+## 2. Current State of browse.py
+
+### 2.1 Code Organization
+
+The script is organized into logical sections with clear headers:
+
+```
+CONFIG
+FETCH
+FILTERS
+FORMATTING
+BROWSE
+FORMAT
+DISPLAY
+TELEGRAM
+MAIN
+```
+
+**Issues:**
+- Lines are excessively long (erowse ~750 lines, some functions are very dense)
+- `print_browse()` function is ~120 lines — too long to review mentally
+- `send_to_telegram()` function is ~100 lines — also too long
+- `format_detail_event()` has deeply nested list comprehensions
+- No type hints anywhere
+- No docstrings on main functions (only on helper functions)
+
+### 2.2 Line Length Issues (CRITICAL)
+
+The user specifically asked about this. Here are the longest lines:
+
+| Line | Length | Issue |
+|------|--------|-------|
+| ~line 100 | ~180 chars | `fetch_page()` URL construction |
+| ~line 160 | ~160 chars | `fetch_all_pages()` loop |
+| ~line 210 | ~200 chars | `is_tradeable_event()` ML market checks |
+| ~line 240 | ~180 chars | `is_tradeable_event()` datetime parsing |
+| ~line 300 | ~180 chars | `get_match_time_status()` datetime math |
+| ~line 380 | ~200 chars | `format_detail_event()` list comprehension |
+| ~line 470 | ~220 chars | `print_browse()` event formatting |
+| ~line 540 | ~180 chars | `send_to_telegram()` message building |
+
+**Root cause:** The code was written for functionality, not readability. String concatenation and nested conditionals make lines very long.
+
+### 2.3 Proposed Solutions for Line Length
+
+**Option A: Refactor to shorter lines (Recommended)**
+- Break long URL constructions into multiple lines
+- Extract nested conditionals into helper variables
+- Use intermediate variables for complex expressions
+- Target: max 120 characters per line
+
+**Option B: Add unit tests**
+- Write unit tests that verify behavior without needing to read every line
+- Tests serve as executable documentation
+- Anyone can run `pytest` to verify correctness
+- See Section 3 for details
+
+**Option C: Both (Recommended)**
+- Refactor for readability
+- Add unit tests for critical paths
+- This is the best approach
+
+### 2.4 Function-by-Function Analysis
+
+#### `fetch_page()` (~35 lines)
+**What it does:** Fetches one page from Polymarket API with retry logic  
+**Issues:**
+- URL construction is on one long line
+- Exponential backoff is clear but verbose
+- Could use `requests` library instead of curl subprocess
+
+**Suggestions:**
+- Break URL construction into multiple `params = {...}` style
+- Consider using `httpx` or `requests` instead of curl subprocess
+
+#### `fetch_all_pages()` (~25 lines)
+**What it does:** Paginates through all results  
+**Issues:**
+- `time.sleep(0.2)` is hardcoded — should be configurable
+- No progress indicator for large fetches
+
+**Suggestions:**
+- Add progress callback option
+- Make inter-page delay configurable
+
+#### `is_tradeable_event()` (~70 lines)
+**What it does:** Complex filter for tradeable match markets  
+**Issues:**
+- This is the longest function at ~70 lines
+- Multiple filter conditions stacked vertically (good) but with long lines (bad)
+- Bare `except:` clauses that catch everything
+
+**Suggestions:**
+- Extract `is_bo2_tie()` check (already done — good)
+- Extract datetime comparisons into helper functions
+- Add early returns to reduce nesting
+- Change bare `except:` to specific exceptions
+
+#### `is_tradeable_market()` (~20 lines)
+**What it does:** Filter for individual markets  
+**Issues:**
+- Very similar to `is_tradeable_event()` — code duplication
+- Could reuse logic from the event version
+
+**Suggestions:**
+- Consider unifying with `is_tradeable_event()`
+
+#### `get_match_time_status()` / `get_match_time_str()` (~50 lines combined)
+**What it does:** Time formatting for display  
+**Issues:**
+- Duplicate logic — both functions do similar things
+- WIB (UTC+7) is hardcoded — user is Indonesian, but this should be configurable
+
+**Suggestions:**
+- Consolidate into one function that returns both values
+- Make timezone configurable
+
+#### `print_browse()` (~120 lines)
+**What it does:** Main display function for CLI output  
+**Issues:**
+- ~120 lines is too long to review mentally
+- Mixes display logic with data formatting
+- Has its own datetime import (Python import inside function — anti-pattern)
+
+**Suggestions:**
+- Break into smaller functions:
+  - `format_match_line()`
+  - `format_non_match_line()`
+  - `print_match_section()`
+  - `print_non_match_section()`
+
+#### `send_to_telegram()` (~100 lines)
+**What it does:** Telegram integration  
+**Issues:**
+- ~100 lines too long
+- Complex chunking logic for Telegram 4096 char limit
+- HTML escaping not handled
+
+**Suggestions:**
+- Extract chunking logic into separate function
+- Add HTML escaping helper
+- Consider using `python-telegram-bot` library instead of curl
+
+#### `format_detail_event()` (~30 lines)
+**What it does:** Formats event with all markets for detail view  
+**Issues:**
+- List comprehension is deeply nested and hard to read
+- ~15-line dict construction
+
+**Suggestions:**
+- Break the dict construction into multiple lines
+- Extract market formatting into helper
+
+### 2.5 Error Handling
+
+| Issue | Severity | Notes |
+|-------|----------|-------|
+| Bare `except:` clauses | Medium | Catches KeyboardInterrupt, SystemExit |
+| No logging | Low | Uses print statements |
+| No structured errors | Low | Could benefit from custom exceptions |
+
+### 2.6 Missing Features/Bugs
+
+| Issue | Severity | Notes |
+|-------|----------|-------|
+| No test suite | High | Cannot verify correctness automatically |
+| WIB hardcoded | Medium | Timezone should be configurable |
+| No cache option | Low | Could cache results for repeated queries |
+| `--detail` uses 1-indexed but docs unclear | Low | Works, but could be confusing |
+| BO2 tie detection uses title match | Medium | Relies on "BO2" in title — fragile |
+| `is_bo2_tie()` checks child_moneyline closed | Medium | API may not always set this flag |
+
+---
+
+## 3. Recommended Improvements
+
+### 3.1 Code Refactoring (Priority: HIGH)
+
+**Goal:** Make browse.py reviewable by humans
+
+**Specific changes:**
+
+1. **Break `print_browse()` into helper functions:**
+   ```python
+   def format_match_line(i, e, ml, outcomes, prices, vol, title, url, ...):
+       """Format a single match event line."""
+       ...
+   
+   def print_match_section(match_events, ...):
+       """Print the MATCH MARKETS section."""
+       ...
+   ```
+
+2. **Break `send_to_telegram()` into helper functions:**
+   ```python
+   def escape_html(text):
+       """Escape HTML special characters."""
+       ...
+   
+   def chunk_telegram_message(lines, max_len=4096):
+       """Split long messages into chunks."""
+       ...
+   ```
+
+3. **Break long lines:**
+   - URL construction: use `params = {...}` dict style
+   - Long conditionals: extract to named variables
+   - Long f-strings: break across multiple lines
+
+4. **Add type hints:**
+   ```python
+   def fetch_page(q: str, page: int = 1, ...) -> Optional[dict]:
+   ```
+
+5. **Consolidate duplicate time functions:**
+   - `get_match_time_status()` and `get_match_time_str()` share logic
+   - Create one function returning both
+
+### 3.2 Unit Tests (Priority: HIGH)
+
+**Goal:** Enable human review via test execution, not line-by-line reading
+
+**Proposed test structure:**
+```
+tests/
+  __init__.py
+  test_filters.py      # is_match_market, is_tradeable_event, is_tradeable_market
+  test_formatters.py   # format_odds, prob_to_cents, get_match_time_*
+  test_browse.py       # Integration tests with mocked API
+  test_cli.py          # Argument parsing tests
+```
+
+**Test examples:**
+
+```python
+# test_formatters.py
+def test_prob_to_cents():
+    assert prob_to_cents(0.30) == 30
+    assert prob_to_cents(0.95) == 95
+    assert prob_to_cents(0.001) == 0
+
+def test_format_odds():
+    assert format_odds(0.30) == "30c"
+    assert format_odds(0.95) == "95c"
+
+# test_filters.py
+def test_is_match_market_with_series():
+    e = {"seriesSlug": "csg", "gameId": "123", "title": "Team A vs Team B"}
+    assert is_match_market(e) == True
+
+def test_is_match_market_vs_syntax():
+    e = {"title": "Team A vs Team B"}
+    assert is_match_market(e) == True
+
+def test_is_match_market_non_match():
+    e = {"title": "Tournament Winner"}
+    assert is_match_market(e) == False
+
+# test_filters.py - is_tradeable_event
+def test_bo2_tie_filter():
+    """BO2 matches ending 1-1 should be filtered out."""
+    e = create_bo2_event(ended_tie=True)
+    assert is_tradeable_event(e) == False
+
+def test_converged_market_filter():
+    """Market with bestBid >= 0.99 should be filtered."""
+    e = create_event_with_ml(bestBid=0.99, bestAsk=0.99)
+    assert is_tradeable_event(e) == False
+```
+
+**Mock API responses needed:**
+- Store sample API responses in `tests/fixtures/` as JSON
+- Use `responses` or `requests-mock` to mock HTTP calls
+
+### 3.3 Documentation Improvements (Priority: MEDIUM)
+
+1. Add troubleshooting section to SKILL.md
+2. Add concrete usage examples
+3. Add HTML escape notes for Telegram
+4. Add changelog
+5. Document the 1-indexed `--detail` argument more clearly
+
+### 3.4 Configuration Options (Priority: LOW)
+
+1. Make timezone (WIB) configurable via `--timezone` argument or env var
+2. Make inter-page delay configurable
+3. Add `--json` output option for programmatic use
+

+
+## 6. Security Audit
+
+### 6.1 Severity Classification
+
+| Severity | Meaning |
+|----------|---------|
+| CRITICAL | Immediate action required. Users should stop using the skill until fixed. |
+| HIGH | Serious vulnerability. Fix as soon as possible. |
+| MEDIUM | Moderate issue. Fix in normal development cycle. |
+| LOW | Minor issue. Fix when convenient. |
+
+---
+
+### 6.2 CRITICAL: Telegram Bot Token Exposed in Process Listings
+
+**Location:** Lines 598-606 (`send_to_telegram()`)
+
+**Description:**
+The Telegram bot token is passed as a subprocess argument to `curl`, making it visible in the process command line. On any Unix system, any user can view all running processes' command lines via `ps aux` or `/proc/*/cmdline`.
+
+**Proof of Concept:**
+```bash
+# While the script is running (or just after it finishes):
+ps aux | grep curl
+
+# Output reveals token:
+# curl -s https://api.telegram.org/bot123456789:ABCdefGHI/sendMessage -d chat_id=... -d text=...
+```
+
+**Impact:**
+- Any user on a shared system can steal the bot token
+- Attacker can send arbitrary messages from the bot
+- Attacker can use the bot for spam, phishing, or social engineering
+- If the bot is in group chats, attacker can extract member information
+
+**Fix:**
+Use curl with `--oauth2-bearer` or environment variable approach. The bot token should NEVER appear in the command line. Recommended fix:
+
+```python
+import os
+
+def send_to_telegram(...):
+    bot_token = os.environ.get("BOT_TOKEN")
+    chat_id = os.environ.get("CHAT_ID")
+    if not bot_token or not chat_id:
+        return
+    
+    env = os.environ.copy()
+    # Use a temp file or proper curl auth method
+    # Actually Telegram bot tokens cannot be passed via header
+    # Instead: use Python's requests library which handles this securely
+    # OR: write token to a file with 0600 perms and use curl's --config option
+```
+
+**Proper fix using Python `requests` library:**
+```python
+import requests
+
+def send_to_telegram(...):
+    bot_token = os.environ.get("BOT_TOKEN")
+    chat_id = os.environ.get("CHAT_ID")
+    if not bot_token or not chat_id:
+        return
+    
+    url = f"https://api.telegram.org/bot{bot_token}/sendMessage"
+    payload = {"chat_id": chat_id, "text": text, "parse_mode": "HTML"}
+    # Token stays in memory, never in command line
+    resp = requests.post(url, data=payload, timeout=10)
+```
+
+**Interim mitigation:** If you must use curl, write the token to a temporary file with mode 0600 and use curl's `--config` flag, then delete the file immediately after.
+
+---
+
+### 6.3 HIGH: HTML Injection in Telegram Messages (XSS-adjacent)
+
+**Location:** Lines 614-661 (`send_to_telegram()`)
+
+**Description:**
+Event titles and other data from the Polymarket API are inserted directly into Telegram messages with `parse_mode=HTML`. No HTML escaping is performed. Characters like `<`, `>`, `&` are not escaped.
+
+**Attack scenario:**
+1. Polymarket (or an attacker who compromises Polymarket data) includes a malicious title like:
+   - `<script>alert('XSS')</script>` 
+   - `<img src=x onerror=alert(1)>`
+   - `Team A &amp; Team B` (ampersand not escaped renders as `&amp;amp;` or breaks parsing)
+2. The bot sends this to Telegram
+3. Telegram renders the HTML, potentially executing JavaScript in the context of the Telegram web client
+
+**Note:** Telegram's HTML parser is restrictive (`<b>`, `<i>`, `<a>`, etc. only), so classic XSS is limited. However:
+- Malformed HTML can crash the Telegram client
+- Attribute-based injections in `<a>` tags could be possible
+- The `<` and `>` characters themselves are illegal in Telegram HTML and will cause parse errors
+
+**Current vulnerable code (simplified):**
+```python
+title = e.get("title", "?")
+lines.append(f"<b>{i}.</b> <a href=\"{url}\">{title_clean}</a>")
+# title_clean is title.split(" - ")[0].strip() -- no HTML escaping
+```
+
+**Fix:**
+```python
+import html
+
+def escape_html(text):
+    """Escape HTML special characters for Telegram."""
+    return (text
+        .replace("&", "&amp;")
+        .replace("<", "&lt;")
+        .replace(">", "&gt;")
+        .replace('"', "&quot;"))
+
+title = e.get("title", "?")
+title_escaped = escape_html(title_clean)
+lines.append(f"<b>{i}.</b> <a href=\"{url}\">{title_escaped}</a>")
+```
+
+---
+
+### 6.4 MEDIUM: Insufficient Input Sanitization on `--search` Parameter
+
+**Location:** Line 39 (`fetch_page()`)
+
+**Description:**
+The `--search` argument is only sanitized with `.replace(' ', '%20')`. This only handles spaces. Other URL-sensitive characters (`#`, `?`, `&`, `%`, `+`, etc.) are not properly URL-encoded.
+
+**Attack scenario:**
+A user passes `--search "Team%20A"` expecting to search for "Team%20A" literally, but `%20` gets decoded to a space by the URL parser, searching for "Team A" instead.
+
+More concerning: if the search term contains `#`, it could truncate the query:
+```bash
+--search "Team#A"  -> URL becomes ?q=Team#A&limit=50...
+# Everything after # is treated as URL fragment, not part of the query
+```
+
+**Current code:**
+```python
+url = (f"{base}?q={q.replace(' ', '%20')}&limit={PAGE_SIZE}&page={page}"
+       f"&search_profiles=false&search_tags=false"
+       f"&keep_closed_markets=0&events_status=active&cache=false")
+```
+
+**Fix:**
+Use `urllib.parse.quote()` for proper URL encoding:
+```python
+from urllib.parse import quote
+
+def fetch_page(q, page=1, ...):
+    base = "https://gamma-api.polymarket.com/public-search"
+    encoded_q = quote(q, safe='')
+    url = (f"{base}?q={encoded_q}&limit={PAGE_SIZE}&page={page}"
+           ...)
+```
+
+---
+
+### 6.5 MEDIUM: No Bounds Checking on `--detail` Argument
+
+**Location:** Lines 778-785 (`main()`)
+
+**Description:**
+The `--detail N` argument is used to index into `result["match_events"]` without proper bounds checking. While there is a fallback (`idx = 0` if out of range), the logic silently defaults to index 0, which may not be what the user intended.
+
+```python
+idx = args.detail - 1  # User provides 1-indexed
+if idx < 0 or idx >= len(result["match_events"]):
+    idx = 0  # Silently defaults to first event
+detail_event = result["match_events"][idx]
+```
+
+**Impact:**
+- Low security impact, but confusing UX
+- User expects event #100 but gets event #1 silently
+
+**Fix:** Warn user if index is out of range instead of silently defaulting.
+
+---
+
+### 6.6 MEDIUM: Potential Denial of Service via Large API Response
+
+**Location:** Lines 53, 79-81, 357-358, 393-403
+
+**Description:**
+The code loads the entire API response into memory via `json.loads()`. If a malicious or compromised Polymarket API returned an extremely large JSON payload (gigabytes), the script could exhaust system memory.
+
+**Additional issue:** `fetch_all_pages()` loops up to 100 pages, each with up to 50 events. While bounded, there's no size limit on individual events or their nested `markets` arrays.
+
+**Fix:**
+```python
+# Add response size limits
+MAX_RESPONSE_SIZE = 10 * 1024 * 1024  # 10MB
+if len(r.stdout) > MAX_RESPONSE_SIZE:
+    raise ValueError(f"API response too large: {len(r.stdout)} bytes")
+```
+
+---
+
+### 6.7 LOW: Bare `except:` Clauses Swallow Security-Relevant Errors
+
+**Location:** Lines 169, 183, 269, 308, 456
+
+**Description:**
+Bare `except: pass` catches ALL exceptions including `KeyboardInterrupt`, `SystemExit`, `MemoryError`, and `OSError`. This silently hides errors that might indicate security problems (e.g., timeouts could suggest a DoS attack in progress).
+
+**Current code:**
+```python
+try:
+    end_dt = datetime.fromisoformat(end_str.replace('Z', '+00:00'))
+    ...
+except:
+    pass  # Silently ignores ALL errors
+```
+
+**Fix:**
+```python
+try:
+    end_dt = datetime.fromisoformat(end_str.replace('Z', '+00:00'))
+    ...
+except (ValueError, TypeError):
+    pass  # Only catch expected exceptions
+```
+
+---
+
+### 6.8 LOW: No Rate Limiting on API Calls (DoS vector)
+
+**Location:** Lines 74-76 (`fetch_all_pages()`)
+
+**Description:**
+An attacker who can pass arguments to this script (e.g., via a web wrapper) could repeatedly call the Polymarket API in a loop, potentially:
+1. Getting the user's IP rate-limited or banned by Polymarket
+2. Consuming the user's bandwidth
+3. Causing resource exhaustion on the host
+
+**Fix:** Add a cooldown between runs if called repeatedly, or use a token bucket rate limiter.
+
+---
+
+### 6.9 Security Summary Table
+
+| # | Issue | Severity | Exploitable Remotely | Fix Complexity |
+|---|-------|----------|----------------------|----------------|
+| 1 | Telegram bot token in process cmdline | CRITICAL | No (local access needed) | Easy |
+| 2 | HTML injection in Telegram messages | HIGH | No (needs Polymarket compromise) | Easy |
+| 3 | Insufficient `--search` sanitization | MEDIUM | Yes (any user input) | Easy |
+| 4 | No bounds check on `--detail` | MEDIUM | Yes (any user input) | Trivial |
+| 5 | Large API response can exhaust memory | MEDIUM | Yes (API or MITM) | Easy |
+| 6 | Bare `except:` swallows errors | LOW | No | Trivial |
+| 7 | No API rate limiting | LOW | Yes (with script access) | Medium |
+
+---
+
+### 6.10 Recommended Immediate Actions
+
+**If you are currently using this skill with a Telegram bot:**
+
+1. **ROTATE YOUR BOT TOKEN IMMEDIATELY** — Go to @BotFather and use `/revoke` to invalidate the current token. Generate a new one.
+
+2. **Do not use the `--telegram` flag** on shared/multi-user systems until Issue #1 is fixed.
+
+3. **Do not use `--search` with untrusted input** until Issue #3 is fixed.
+
+4. Monitor your Telegram bot's `getUpdates` for unauthorized access.
+
+**Safe usage until fixes are deployed:**
+```bash
+# Without Telegram (safe):
+polymarket-browse --category "Counter Strike" --limit 5
+
+# With Telegram (UNSAFE on shared systems until fix is deployed):
+# NOT RECOMMENDED until security issues are addressed
+```
+
+---
+
+### 6.11 Fix Priority Order
+
+1. **FIRST (CRITICAL):** Fix Telegram bot token exposure — use Python `requests` library instead of curl subprocess, OR use curl with `--config` file approach
+2. **SECOND (HIGH):** Add HTML escaping for Telegram messages
+3. **THIRD (MEDIUM):** Fix `--search` URL encoding with `urllib.parse.quote()`
+4. **FOURTH (MEDIUM):** Add `--detail` bounds checking
+5. **FIFTH (MEDIUM):** Add response size limits
+6. **SIXTH (LOW):** Replace bare `except:` with specific exceptions

+| 561 | 126 | `print_detail()` | Spread formatting |

+| 728 | 112 | `send_to_telegram()` | Telegram send call |
+| 569 | 110 | `print_detail()` | Market spread formatting |
+
+**Key finding:** The `print_browse()` function signature itself (line 474) at 209 chars is the longest. This should be broken up or the function should accept a config dict instead of 11 parameters.
+
+---
+
+## Appendix B: Duplicate Code Patterns
+
+### B.1 Time formatting duplicated across 3 functions
+
+| Function | Lines | Purpose |
+|----------|-------|---------|
+| `get_match_time_status()` | ~40 | Returns (status_str, urgency) tuple |
+| `get_match_time_str()` | ~35 | Returns just status string |
+| `get_start_time_wib()` | ~50 | Returns (abs_str, rel_str) tuple |
+
+All three parse the same ISO datetime string and compute the same relative time logic. Should be consolidated into one function returning all needed values.
+
+### B.2 `is_tradeable_event()` vs `is_tradeable_market()`
+
+Both check convergence (bestBid >= 0.99, bestAsk <= 0.01) and acceptingOrders/closed status. The market-level one is simpler but they share the same convergence check logic.
+
+---
+
+## Appendix C: Potential Bugs
+
+### C.1 Bare `except:` clauses
+
+Found at lines 169, 183, and similar locations:
+```python
+except:
+    pass
+```
+
+**Risk:** Catches KeyboardInterrupt, SystemExit, and json.JSONDecodeError. Should be:
+```python
+except (ValueError, TypeError):
+    pass
+```
+
+### C.2 Line 474: `print_browse()` signature is 209 characters
+
+```python
+def print_browse(match_events, non_match_events, category, total_raw, total_fetched, total_match, total_non_match, raw_mode=False, partial=False, non_matches_max=5, matches_only=False, non_matches_only=False):
+```
+
+**Issue:** 11 parameters is too many. Consider using a result dict or a config object.
+
+**Fix options:**
+1. Accept a `BrowseResult` namedtuple/dataclass
+2. Split into `print_browse_header()` and `print_browse_sections()`
+3. Use `**kwargs`
+
+### C.3 Line 128 in `send_to_telegram()`: `bot_token=os.environ.get("BOT_` (truncated)
+
+```python
+bot_token=os.environ.get("BOT_TOKEN")
+chat_id = os.environ.get("CHAT_ID")
+```
+
+This looks like a line that was cut off in the output but the actual code is fine. However, it highlights that the line at 582 is long.
+
+### C.4 `chunk_len` variable unused
+
+At line 681 in `send_to_telegram()`:
+```python
+chunk = []
+chunk_len = 0  # NEVER USED
+chunk_num = 1  # NEVER USED
+```
+
+---
+
+## Appendix D: Missing Test Coverage
+
+Functions that need tests but have none:
+
+```
+[x] fetch_page          - needs mock curl response
+[x] fetch_all_pages     - needs mock paginated responses
+[x] is_match_market     - easy to test with dict inputs
+[x] is_tradeable_event  - complex, needs many test cases
+[x] is_tradeable_market - similar to above
+[x] is_bo2_tie          - edge cases for BO2 detection
+[x] get_ml_market        - easy to test
+[x] get_ml_volume        - easy to test
+[x] prob_to_cents        - pure function, easy to test
+[x] format_odds          - pure function, easy to test
+[x] format_spread        - pure function, easy to test
+[x] get_match_time_*     - needs timezone mocking
+[x] get_tournament       - easy to test
+[x] get_event_url        - easy to test
+[x] filter_events        - easy to test
+[x] sort_events          - easy to test
+```

 - `--list-categories` : List available game categories and exit
 - `--raw` : Show all events without tradeable filter (for debugging). Includes fetch stats.
+- `--no-cache` : Disable caching and fetch fresh data from the API.
+- `--max-total` : Maximum total events to fetch before early exit. Default: no limit. Useful for quick snapshots.
+- `--starts-before` : Unix timestamp filter. Only show match events starting before this time (LIVE events always shown regardless of timestamp).

 ## Pagination
 
-The script fetches **ALL pages** until the API runs out of results (up to 100 pages as a safety cap).
+The script fetches **ALL pages** until the API runs out of results.
+
+### Parallel Fetching
+
+Pages are fetched in **parallel batches of 5** using ThreadPoolExecutor. This significantly reduces fetch time:
+
+| Scenario | Without Parallelization | With Parallelization |
+|----------|------------------------|---------------------|
+| 10 pages (50 events) | ~20s (2s per page × 10) | ~4s (2s per batch × 2 batches) |
+| 20 pages (100 events) | ~40s | ~8s |
+
+The script first fetches page 1 to determine total pages, then fetches remaining pages in parallel batches of 5.
 
 ## Rate Limiting
 
-- Exponential backoff: 2s → 4s → 8s → 16s → 32s
+- TokenBucket rate limiter: 10 API calls per second
+- Exponential backoff on retries: 2s → 4s → 8s → 16s → 32s
 - Max 5 retries before aborting
 
+**URL Encoding**: Special characters in `--search` (e.g., `&`, `=`, `%`, `+`, `#`) are properly encoded to prevent URL injection.
+
+## Caching
+
+Results are cached in `~/.cache/polymarket-browse/` with a **5-minute TTL** to reduce redundant API calls.
+
+- Use `--no-cache` to bypass the cache and fetch fresh data
+- Cached data is automatically used when available and not expired
+- Useful when running the script repeatedly (e.g., for monitoring)
+
 ## Odds Format
 
 All odds are shown in **cents** format:
 - `30c` = 0.30 probability
 - `95c` = 0.95 probability
 - `GamerLegion 28c | 72c Team Yandex` = GamerLegion at 28c, Team Yandex at 72c
+
+## Troubleshooting
+
+### "WARNING: Partial fetch" appears
+The API returned incomplete data due to an error/timeout. Results shown may be incomplete. Try again with `--no-cache` to force a fresh fetch.
+
+### No markets appear
+- Verify your category is correct: `--list-categories`
+- Try with `--raw` to see all events (not just tradeable ones)
+- Some categories may have no active match markets at certain times
+
+### Why did my match disappear?
+Matches are filtered out when:
+- They have ended (startTime > 4 hours ago)
+- BO2 matches ended in a tie (1-1)
+- The market has converged (bestBid >= 0.99 or bestAsk <= 0.01)
+- The event has ended (endDate passed)
+
+### Telegram not working
+- Verify `BOT_TOKEN` and `CHAT_ID` environment variables are set
+- Ensure bot is started and chat ID is correct
+- Check Telegram has not blocked the bot
+
+## Examples
+
+### Basic usage
