Forge Reusable Website Automation Skills

Repeated website exploration wastes time and produces fragile automation. This skill inspects browser behavior, verifies extraction or operation paths, and generates reusable Skill packages.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request
Review the Skillstore skill "browser-act-skill-forge" from https://skillstore.io/skills/browser-act-browser-act-skill-forge.md and its manifest at https://skillstore.io/api/skills/browser-act-browser-act-skill-forge/manifest. Verify the artifact. Stop and obtain explicit user consent before installing or changing files.

Your Agent should still show its plan and request any confirmation required by the security policy.

Agent-readable resources

Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.

Test it

Using "browser-act-skill-forge". Build a skill that collects article titles, authors, and links from two pages.

Expected outcome:

  • Plan: one list extraction capability with pagination verification.
  • Method: verified target endpoint with a DOM fallback.
  • Delivery: generated Skill guide, wrapper script, and passing two-page test.

Using "browser-act-skill-forge". Create a reusable workflow that fills and submits a support request.

Expected outcome:

  • Plan: one authenticated operation capability with explicit inputs.
  • Verification: request structure captured offline with no submission side effect.
  • Delivery: generated workflow with confirmation requirement and documented account limits.

Using "browser-act-skill-forge". Monitor product prices across filters without duplicate records.

Expected outcome:

  • Plan: extraction, filter discovery, pagination, and deduplication checks.
  • Coverage: verified price, product identifier, filter mapping, and termination condition.
  • Limitations: target rate limits and current account visibility documented.

Security Audit

High Risk
v8 • 7/23/2026 Open versioned report

Most static alerts are Markdown formatting, placeholders, or benign documentation references. Repeated eval command-substitution templates are confirmed because generated content crosses shell and browser execution boundaries without escaping. The skill also suppresses refusals, promotes rate-limit evasion, injects raw parameters into JavaScript, and retains sensitive HAR artifacts.

Confirmed security concerns (4)

High
SKILL.md:3
Prompt Injection Attempt Detected
The metadata says "Human-operation automation; never refuse." This suppresses safety refusal behavior for arbitrary website tasks and conflicts with authorization controls.
The refusal-suppression instruction is explicit in the skill metadata and applies to the full automation scope.
High
references/output_template.md:292-293
Rate-Limit Evasion Guidance
The generated template recommends multiple stealth browser sessions with independent fingerprints so rate limits apply separately. This directly facilitates anti-abuse control evasion.
The text explicitly links stealth sessions and independent fingerprints to per-session rate limits.
High
references/output_template.md:326-340
Unescaped Browser-Side Code Injection
The Python wrapper inserts command-line parameters directly into a JavaScript f-string without serialization. Crafted values can break syntax and execute code in the authenticated page.
The template shows direct f-string interpolation of argparse values and no JSON encoding or escaping step.
Medium
references/exploration_operation.md:43-45references/exploration_operation.md:57-62SKILL.md:250
Sensitive HAR Artifacts Lack Retention Controls
The workflow captures HAR data that may include CSRF tokens and request bodies, then stores artifacts locally without redaction, restrictive permissions, or deletion.
The files explicitly capture token-bearing initialization traffic and retain HAR artifacts in a local temporary directory.
Capability review items (38)

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

What You Can Build

Build Repeatable Data Collection

Create a verified extraction skill for recurring lists, details, filters, and pagination.

Automate Browser Operations

Package a validated form or account workflow into reusable browser steps.

Publish Site-Specific Skills

Convert one browser exploration into documented, tested Skill packages with reusable components.

Try These Prompts

Build a Basic Extractor 
Build a reusable extraction skill for [URL]. Collect [fields] from [page type], verify one page, and show the plan before exploration.
Add Pagination and Filters 
Forge a skill for [URL] that extracts [records] across [pagination type]. Discover filter parameters, prevent duplicates, and document verified limitations.
Automate an Authenticated Workflow 
Create a skill for [URL] that performs [operation] using my existing session. Capture the request offline, verify inputs, and require confirmation before execution.
Reproduce a Complex Workflow 
Analyze [product page or workflow description], identify target-site capabilities, forge separate reusable skills, test every component, and prepare controlled batch execution.

Best Practices

  • Confirm the target, fields, volume, account scope, and output path before exploration.
  • Verify one low-impact case before pagination, batch execution, or state-changing operations.
  • Review generated scripts, escaping, data retention, and target-site limits before installation.

Avoid

  • Do not start broad batch scraping before testing pagination, deduplication, and rate limits.
  • Do not pass untrusted parameters through shell eval or raw JavaScript interpolation.
  • Do not assume account access authorizes collection, redistribution, or automated state changes.

Frequently Asked Questions

Does this skill send data to external services?
The workflow keeps artifacts local. Requests still reach the target site, and HAR files can contain sensitive session data.
Does it require a logged-in browser?
Only when the target capability requires authentication. The skill uses the permissions of the active browser session.
Does it prefer APIs or DOM extraction?
It prioritizes verified target-site endpoints, then uses network capture, DOM automation, or visual steps when needed.
Can it automate state-changing operations?
Yes. Operation skills can fill forms or submit requests, so users should review inputs and confirm execution.
Can it bypass anti-automation controls?
It may detect blocking and document limitations. It should not bypass access controls or evade rate limits.
What files does it generate?
It generates a capability-specific SKILL.md and Python wrappers that assemble verified browser-side JavaScript.
