README (SKILL.md)
Price Monitor & Daily Excel Report Bot
Overview
Automated price tracking system that monitors products across competitor websites, detects price drops, and delivers a formatted Excel report via email every morning at 8 AM. Saves 3+ hours of manual work per day.
What It Does
- Scrapes prices from target URLs using Selenium (handles JavaScript-rendered pages)
- Compares against previous day's prices automatically
- Highlights price drops >5% in red, increases in green inside Excel
- Emails formatted report to specified recipients on schedule
- Logs all runs with timestamps for auditing
Required Environment Variables
Set these in OpenClaw's Secrets manager before running:
| Variable | Description | Example |
|---|---|---|
SMTP_HOST |
SMTP server hostname | smtp.gmail.com |
SMTP_PORT |
SMTP port number | 587 |
SMTP_USER |
Sender email address | [email protected] |
SMTP_PASS |
Email password or app-specific password | xxxx xxxx xxxx xxxx |
REPORT_RECIPIENT |
Where to send the daily report | [email protected] |
Setup
- Add target product URLs to
config/urls.txt(one URL per line) - Set all environment variables above in OpenClaw Secrets
- Set run schedule in OpenClaw:
daily at 08:00 - Chromium must be available on the host for Selenium headless mode
Usage
"Start monitoring prices for these URLs and email me a report every morning" "Check competitor prices and send Excel summary to [email protected]" "Run price tracker now and show me today's drops" "Add this product URL to the monitoring list"
Output
price_report_YYYY-MM-DD.xlsx— color-coded Excel report- Email with report attached sent to configured recipient
- Console summary: total products, drops found, errors
Rules
- Never send more than 1 request per second to any domain
- Always save raw scraped data before processing (in
data/raw/) - If email delivery fails, save report to
data/reports/and retry once after 10 minutes - If a URL returns 403/blocked, skip and log — do not retry more than 3 times
- Report must include: product name, URL, yesterday's price, today's price, % change

Usage Guidance
This skill appears internally consistent and implements what it claims, but review and consider the following before installing:
- SMTP credentials: Use a dedicated sending account and an app-specific password where possible (do not reuse a personal account password). Limit that account's privileges.
- Chromium / ChromeDriver: The script requires a working headless Chromium + chromedriver on the host; SKILL.md mentions webdriver-manager but the script does not use it — ensure your environment supplies a compatible driver.
- Rate limiting & legality: The script scrapes third-party sites; confirm you have the right to scrape the target sites and obey their robots/ToS. The script enforces a 1.2s delay and a 1 req/sec guideline, but you should verify that rate is acceptable for your targets.
- Data storage: Scraped data and reports are written locally under data/raw and data/reports; ensure sensitive data is stored securely and that recipients are correct to avoid accidental data leaks.
- Testing: Run initially with demo/test URLs and with a safe recipient to validate parsing (price extraction is heuristic and may mis-parse some sites). Monitor logs for frequent errors (403s, parsing failures).
- Minor code hygiene: The script imports requests and lists webdriver-manager as required even though neither is used; this likely reflects leftover dependencies rather than malicious intent.
If you need tighter control, consider: restricting the SMTP account, running the scraper in an isolated environment, and auditing the URL list before running.
Capability Analysis
Type: OpenClaw Skill
Name: argus-price-monitor
Version: 1.0.2
The skill is a standard price monitoring automation tool that uses Selenium for web scraping and SMTP for email reporting. The implementation in `scripts/run.py` is consistent with the functionality described in `SKILL.md`, and it follows good practices such as rate limiting and error logging. No evidence of malicious intent, data exfiltration, or prompt injection was found.
Capability Assessment
Purpose & Capability
Name/description match the implementation: Selenium scraping, pandas/openpyxl for Excel, and SMTP for email. Required secrets (SMTP_HOST/PORT/USER/PASS and REPORT_RECIPIENT) are appropriate for sending reports.
Instruction Scope
SKILL.md instructs the agent to read config/urls.txt, run scheduled scraping, save raw data under data/raw, and email reports — all of which the script implements. The instructions do not request unrelated files, system credentials, or external endpoints beyond SMTP.
Install Mechanism
This is an instruction-only skill with no install spec, so nothing is downloaded on install (low install risk). Minor mismatch: SKILL.md lists webdriver-manager as a dependency but the provided script does not use webdriver-manager; the script assumes a usable Chromium + chromedriver environment. Users must ensure host has Chromium and a Chrome driver available for Selenium.
Credentials
Only SMTP credentials and a recipient address are required; this is proportionate to sending report emails. No unrelated secrets or broad cloud credentials are requested.
Persistence & Privilege
always is false and the skill does not request any elevated or persistent system-wide privileges, nor does it modify other skills or system configs. It stores scraped data locally under data/ and reports under data/reports.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install argus-price-monitor - After installation, invoke the skill by name or use
/argus-price-monitor - Provide required inputs per the skill's parameter spec and get structured output
