    karpathy-coder

    Use when writing, reviewing, or committing code to enforce Karpathy's 4 coding principles — surface assumptions before coding, keep it simple, make surgical changes, define verifiable goals. Triggers on "review my diff", "check complexity", "am I overcomplicating this", "karpathy check", "before I commit", or any code quality concern where the LLM might be overcoding.

    Honestly evaluate AI work quality using a two-axis scoring system. Use after completing a task, code review, or work session to get an unbiased assessment. Detects score inflation, forces devil's advocate reasoning, and persists scores across sessions.

We split this skill into the rules it gives an agent

7 rules. 0 are common, 6 are distinctive, and 1 is very specific to this project.

“Common” is measured: kept by at least 6 in 10 of the 36 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Browser Automation

Category: Engineering Domain: Web Automation

Overview

The Browser Automation skill provides tools for building robust web automation, checking scripts for bot detection signatures, generating form automation code, and creating web scraping solutions with rate limiting and best practices.

Clarify First

Before generating automation, confirm these inputs. If any is unknown or vague, ASK — do not assume:

  • Target site & task — the URL and exactly what to automate or scrape (drives the generated selectors and flow)
  • Which tool — audit an existing script, build form automation, or generate a scraper (selects anti_detection_checker.py vs form_automation_builder.py vs scraping_toolkit.py)
  • Politeness strategy & authorization — polite vs aggressive, robots.txt compliance, and that you are permitted to automate this target (sets request delays and backoff in the generated code)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Quick Start

# Check automation script for detection signatures
python scripts/anti_detection_checker.py --file ./my_scraper.py

# Generate form automation code from HTML
python scripts/form_automation_builder.py --url https://example.com/form --output form_script.py

# Generate scraping code with rate limiting
python scripts/scraping_toolkit.py --url https://example.com --strategy polite --output scraper.py

Tools Overview

ToolPurposeKey Flags
anti_detection_checker.pyAudit automation code for bot detection signatures--file, --format
form_automation_builder.pyGenerate form filling scripts from HTML analysis--url, --html-file, --output
scraping_toolkit.pyGenerate web scraping code with rate limiting--url, --strategy, --output

Workflows

Build Reliable Scraper

  1. Analyze target with scraping_toolkit.py to generate base code
  2. Check generated code with anti_detection_checker.py
  3. Address any detection signatures found
  4. Test with progressive rate limiting

Automate Form Submission

  1. Provide form HTML to form_automation_builder.py
  2. Review generated script for field mappings
  3. Customize data sources and validation
  4. Run anti-detection check on final script

Reference Documentation

  • Browser Automation Guide - Anti-detection techniques, rate limiting strategies, ethical scraping practices

Common Patterns

Polite Scraping

  • Respect robots.txt directives
  • Implement exponential backoff on errors
  • Use 2-5 second delays between requests
  • Identify your bot with a descriptive User-Agent
  • Cache responses to minimize repeat requests

Anti-Detection Best Practices

  • Rotate User-Agent strings realistically
  • Randomize request timing (avoid fixed intervals)
  • Handle cookies and sessions properly
  • Avoid headless browser fingerprinting tells

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
