Customising Your TorlyAI Visa Assessment: Developer Guide to AI Rule Plugins

Tailoring Your Immigration Rule Engine with TorlyAI Plugins

If you build or maintain an immigration rule analyser, you know the pain of adapting to evolving Home Office policies. Torly.ai’s AI rule engine lets you plug in custom rules, so your Innovator Visa checks stay sharp. This guide dives into developer tools and best practices to extend Torly.ai’s system for personalised visa assessments.

You’ll learn how to register new rules, shift from legacy patterns and test your plugins end to end. By the end, you’ll have a bespoke framework within Torly.ai’s core platform that checks business viability, founder credentials and gap analysis exactly the way you need. Ready to explore the engine behind our immigration rule analyzer – AI-Powered UK Innovator Visa Application Assistant?

Why Extend Your Immigration Rule Analyzer?

Building rules for visa readiness can feel rigid. Out-of-the-box checks might flag too much or miss critical nuances. When you customise:

  • You adapt instantly to Home Office updates.
  • You apply bespoke criteria from your endorsing body.
  • You create context-aware fixes, not generic advice.

Torly.ai’s plugin system uses an event-driven approach. Instead of hacking core code, you author discrete rule modules. Each rule is self-contained, shares metadata and hooks into the main engine at runtime. That means you deploy updates without downtime and keep your assessments precise.

Overview of TorlyAI’s Plugin Architecture

Under the hood, Torly.ai follows a similar model to modern static analysis frameworks. Key concepts include:

  1. Plugin registration
  2. Rule definition
  3. Node or event processing
  4. Automated fixes and suggestions

When you install a plugin, Torly.ai scans for definitions and integrates them into torly analyse—our unified command for built-in and custom diagnostics. No more two-step processes. Everything runs in a single pass, giving you a consolidated report on idea qualification, founder metrics and roadmap generation.

This unification speeds up feedback loops. As soon as you push a new rule, it lands in staging and your team sees failures or improvements right away.

Setting Up Your Development Environment

Before writing rules, get your workstation ready:

  • Install Node.js (v16+) or Python (3.9+)—Torly.ai supports both runtimes.
  • Clone the torly-rule-plugins repo from GitHub.
  • Run npm install or pip install -r requirements.txt.
  • Ensure you have API credentials for Torly.ai’s sandbox environment.

You can also use the desktop version for local testing. If you prefer a GUI for debugging plugins, Download our TorlyAI Desktop APP to author and preview rule logic interactively. It packages the full engine and lets you step through your rules line by line.

Defining a New Immigration Rule

Creating a rule is straightforward. In your codebase:

  1. Create a new file, e.g. my_custom_rule.ts or my_custom_rule.py.
  2. Extend BaseRule and supply a unique name and description.
  3. Implement the validate method to inspect applicant data or business plans.
  4. Optionally define a fix that suggests a change or additional evidence.

Here’s a conceptual example in pseudocode:

class CheckInvestmentThreshold extends BaseRule {
  constructor() {
    super({
      name: 'check_investment_threshold',
      description: 'Ensure startup investment meets the Innovator Visa minimum.',
    });
  }

  async validate(context) {
    const amount = context.getField('investmentAmount');
    if (amount < 50000) {
      context.report({
        code: this.name,
        message: `Investment is only £${amount}, minimum is £50,000.`,
        fix: { suggestion: 'Increase investment or seek additional funding.' },
      });
    }
  }
}

Once your rule class is ready, register it in plugin.yaml:

plugins:
  - module: ./my_custom_rule
    rule: CheckInvestmentThreshold

After saving, your rule deploys when you run torly analyse.

Migrating Existing Rules to TorlyAI Plugin System

If you’ve been using an older integration or a third-party add-on, follow these steps:

  1. Identify legacy rule classes: Locate any rules extending LegacyRuleBase.
  2. Map to new API: Replace LegacyRuleBase with BaseRule or AnalysisRule.
  3. Update registration: Shift from manual imports to plugin.yaml.
  4. Revise validation hooks: Move from callback functions to structured validate methods.
  5. Test in bulk: Run torly analyse --all to catch issues immediately.

This mirrors how Flutter developers moved from one lint package to the integrated analyzer. You’ll see fewer steps, better performance and a single command for diagnostics.

Now, you can adopt the same workflow for your visa logic without juggling multiple tools. Discover our immigration rule analyzer, an AI-Powered UK Innovator Visa Application Assistant and streamline your pipeline.

Testing Your Custom Rules

Once your plugin loads, you need to test:

  • Unit tests: Mock RuleContext and supply sample applicant profiles.
  • Integration tests: Run torly analyse --sample-data=innovator.json.
  • Edge cases: Check empty fields, boundary investments and unusual business structures.

Torly.ai’s test harness includes utilities to simulate API calls. You can also plug in CI pipelines so that every pull request triggers a full rule suite. When a rule fails, the harness returns structured output, making reviews fast and clear.

For scenarios where you want a local desktop preview, you can still fall back on the TorlyAI Desktop Application. It graphs your rules, shows execution traces and helps you spot logic flaws interactively. No more guesswork.

Best Practices and Tips

To make your rule modules robust:

  • Keep rules small and focused. One rule, one responsibility.
  • Share common utilities via a shared module for checks like date parsing.
  • Document your rules inline so non-technical reviewers understand the logic.
  • Version your plugins in Git and tag releases semantically.

It’s easy to drift when you have dozens of rules. A regular review cycle ensures you retire outdated checks and refine suggestions as policy evolves.

And if you’re building a complex business plan feature, remember Torly.ai comes with an AI-driven business plan generator. It crafts narratives that align with EB expectations and supports multiple drafts.
