What it does

Reddit Browser Automation is an agent skill from MassLab-SII/open-agent-skills. This skill provides tools and techniques for Postmill/Reddit-like forum automation. Includes account creation, posting, forum creation and wiki management. Suitable for tasks requiring complex operations on forum platforms.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts (for example `scripts/browser_client.py`, `scripts/browser_server.py` and `scripts/create_forum.py`).

It sits in Productivity & Automation, covering Browser automation. It works with Reddit. The repository describes itself as: We are dedicated to building a set of open agent skills that deliver superior performance, higher determinism, and greater consistency on targeted tasks, while operating at a… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Browser automation

Example prompts

  • “/reddit-browser-automation”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Sign Up
  2. Create Post
  3. Create Forum
  4. Create Wiki

What it can do on your machine

Read from SKILL.md and the folder at commit ece5fab. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 8 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Reddit Browser Automation loads about 1.6k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 468 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Reddit/Postmill Browser Automation Skill

This skill is based on Playwright MCP tools, providing automation capabilities for Reddit-like forum platforms (Postmill).

Core Concepts

In forum automation, we distinguish two types of operations:

  1. Skill: Meaningful combinations of multiple tool calls, encapsulated as independent Python scripts
  2. Basic Tools: Single function calls used for atomic operations.

I. Skills

1. Sign Up

Use Cases:

  • Create a new account on the forum after cilcing "Sign up" button
  • Register with specific username and password

Usage:

bash
# Usage:
#   python sign_up.py <username> <password> <username_ref> <password_ref> <password_repeat_ref> <submit_ref>
# Example:
python sign_up.py "AIDataAnalyst2025" "SecurePass123!" e35 e43 e44 e54

2. Create Post

Use Cases:

  • Submit a new post/submission to a forum aftering clicking "Submit" button
  • Create text posts with title and body

Usage:

bash
# Usage:
#   python create_post.py <title> <body> <title_ref> <body_ref> <create_btn_ref>
# Example:
python create_post.py "My Post Title" "Post body content here" e58 e63 e82

Note: The body text can contain multiple lines. Each line should start with a dash (-) for proper formatting.


3. Create Forum

Use Cases:

  • Create a new forum/community after clicking "Create forum" button
  • Set up forum name, title, description, and sidebar

Usage:

bash
# Usage:
#   python create_forum.py <name> <title> <description> <sidebar> <name_ref> <title_ref> <desc_ref> <sidebar_ref> <create_btn_ref>
# Example:
python create_forum.py "BudgetEuropeTravel" "Budget Travel Europe" "Community for sharing money-saving tips" "Share your best deals!" e51 e56 e61 e69 e83

4. Create Wiki

Use Cases:

  • Create a wiki page for a forum after clicking "Create new page" button
  • Set up wiki URL path, title, and content

Usage:

bash
# Usage:
#   python create_wiki.py <url_path> <title> <body> <url_ref> <title_ref> <body_ref> <save_btn_ref>
# Example:
python create_wiki.py "europe-travel-guide" "Complete Budget Travel Guide" "Wiki content here" e51 e56 e62 e69

II. Basic Tools (When to Use Single Functions)

Below are the basic tool functions and their use cases. These are atomic operations for flexible combination.

Note: Code should be written without line breaks.

How to Run
bash
# Standard format (browser persists across calls)
python run_browser_ops.py -c "await browser.navigate('http://localhost:9999')"
Navigation Tools
navigate(url: str)

Use Cases:

  • Open forum homepage
  • Navigate to specific forum or post

Example:

bash
python run_browser_ops.py -c "await browser.navigate('http://localhost:9999')"
python run_browser_ops.py -c "await browser.navigate('http://localhost:9999/f/MachineLearning')"

navigate_back()

Use Cases:

  • Go back to previous page
  • Return to forum listing after viewing post

Example:

bash
python run_browser_ops.py -c "await browser.navigate_back()"

Interaction Tools
click(ref: str, element: Optional[str] = None)

Use Cases:

  • Click navigation links (Forums, Submit, Wiki, etc.)
  • Click forum links and post titles
  • Click buttons (Sign up, Create, Save, Upvote, etc.)
  • Click pagination links (More, Page 2, etc.)

Example:

bash
# Click Forums link
python run_browser_ops.py -c "await browser.click(ref='e22', element='Forums link')"

# Click a post title
python run_browser_ops.py -c "await browser.click(ref='e77', element='Post title link')"

# Click Upvote button
python run_browser_ops.py -c "await browser.click(ref='e94', element='Upvote button')"

Show full SKILL.md (190 more words)Show less
type_text(ref: str, text: str, element: Optional[str] = None)

Use Cases:

  • Fill form fields (username, password, title, body)
  • Enter search queries
  • Fill wiki content

Example:

bash
# Enter username
python run_browser_ops.py -c "await browser.type_text(ref='e35', text='MyUsername', element='Username field')"

# Enter post body
python run_browser_ops.py -c "await browser.type_text(ref='e63', text='Post content here', element='Body textbox')"

select_option(ref: str, element_desc: str, value: str)

Use Cases:

  • Select timezone in user settings
  • Select sorting options
  • Select dropdown values

Example:

bash
# Select timezone
python run_browser_ops.py -c "await browser.select_option(ref='e56', element_desc='Time zone combobox', value='Europe / Amsterdam')"

press_key(key: str)

Use Cases:

  • Submit search queries (press Enter)
  • Submit forms

Example:

bash
python run_browser_ops.py -c "await browser.press_key('Enter')"

Page State Tools
snapshot()

Use Cases:

  • When unsure about current page state
  • Need to find ref references for elements
  • Verify if operation was successful
  • Count posts or comments on a page

Example:

bash
python run_browser_ops.py -c "await browser.snapshot()"

Best Practices:

  • Use snapshot after navigation to find element refs
  • Use snapshot to count items on a page
  • Use snapshot to verify data before submitting

III. Common Navigation Patterns

Forum Navigation
bash
# Navigate to homepage
python run_browser_ops.py -c "await browser.navigate('http://localhost:9999')"
Sorting and Pagination
bash
# Click Sort by dropdown
python run_browser_ops.py -c "await browser.click(ref='e54', element='Sort by: Hot dropdown')"

IV. Best Practices

Use snapshot() Liberally

Use snapshot() in the following situations:

  • After navigating to a new page
  • Before performing actions that require element refs
  • When counting posts or analyzing content
  • To verify successful completion of actions

Usage Principles

  1. Navigate first: Start by navigating to http://localhost:9999
  2. Use snapshot() liberally: Forum pages have dynamic refs, verify state often
  3. Find refs: Always find current refs before using skills
