# 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

---

### Appendix A: Longest Lines in browse.py (for targeted refactoring)

| Line | Chars | Location | Content Summary |
|------|-------|----------|-----------------|
| 474 | 209 | `print_browse()` | Function signature |
| 564 | 152 | `print_detail()` | ML odds formatting |
| 571 | 136 | `print_detail()` | Market outcome formatting |
| 760 | 128 | `send_to_telegram()` | Telegram send call |
| 561 | 126 | `print_detail()` | Spread formatting |
| 736 | 122 | `send_to_telegram()` | Telegram API URL |
| 485 | 121 | `print_browse()` | Fetch stats line |
| 467 | 119 | `print_browse()` | Print category header |
| 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
