Skills System

Every person uses an AI assistant differently. Some people want help with coding. Others need a companion for creative writing. Others just want help managing their schedules and groceries. You shouldn't have to explain your preferences every time you start a conversation.

Meggy's Skills system lets the AI learn how you like to work. Skills are structured instruction sets that modify the AI's behavior for specific contexts — think of them as habits you teach your assistant. Once learned, they're automatically applied whenever they're relevant.

Behind the scenes, a context-aware router automatically selects and delivers the right skills to each conversation, backed by an automatic safety analysis pipeline.

What's a Skill?

A skill is a structured instruction set that modifies the AI's behavior. Each skill has:

Bundled Skills

Meggy comes with 63 bundled user skills across 17 categories and 14 protected system skills that power core AI capabilities. System skills are always-on and cannot be disabled — they ensure fundamental behaviors like safety guidelines, companion mode, and output formatting.

Household Bundles

New in March 2026, Meggy ships with four household-focused skill categories designed for everyday family life:

Category Skills What They Do
📚 Education Homework Helper, Math Tutor, Vocabulary Builder, Bedtime Storyteller Guide students through problems with Socratic questioning, generate age-appropriate exercises, and create personalized bedtime stories
🍳 Kitchen Meal Planner, Recipe Finder Create weekly meal plans considering dietary preferences and budget, find recipes from what's in the fridge
💰 Finance Budget Helper, Retirement Planner Track household budgets and savings goals, model retirement scenarios with compound interest calculations
🏠 Home Chore Manager, Home Maintenance Manage family chore rotations with age-appropriate assignments, generate seasonal home maintenance calendars

Skill Priority Tiers

Tier Type Examples Behavior
0 System Safety, core formatting, companion mode Always injected, protected
1 Behavioral Clarification protocol, companion mode Standard priority
2 Domain Coding standards, research methodology Context-dependent injection
3 Task Specific workflow instructions Highest user-defined priority

Managing Skills by Category

You can enable or disable entire categories of skills at once from the Settings → Skills page. Each category chip shows a toggle indicator:

Clicking the toggle on any category chip flips all skills in that category on or off — perfect for quickly enabling the "Education" bundle when the kids are home, or turning off "DevOps" skills when you're not coding.

Plugin Bundles

Categories let you toggle skills one group at a time — but plugins go further. A plugin bundles related skills, tools, hooks, agents, and safety settings into a single package that you enable or disable with one click.

Meggy ships with 14 built-in plugins spanning 8 categories:

Category Plugins What They Include
📚 Education Teaching & Tutoring, Kids Mode 8 skills, content safety filter (strict mode)
🏠 Home Home Automation, Home Management, Home Renovation, Elder Care 12 skills, smart device hooks
💪 Health Doctor & Health, Fitness & Training 6 skills, medical disclaimer
💼 Productivity Work Productivity 11 skills, Google Workspace tools
💻 Coding Developer Toolkit 17 skills, terminal access with approval gates
💰 Finance Finance & Budgeting 4 skills
✍️ Writing Content Creator 7 skills
📊 Business Sales & Research 4 skills

Enable a plugin from Settings → Plugins and all its components activate together — skills turn on, hooks register, tool permissions apply, and safety filters engage. Disable it and everything reverts cleanly.

Plugins that include content safety (like Kids Mode) automatically raise Meggy's content filter level. The filter can only be raised, never lowered, so enabling Kids Mode alongside Developer Toolkit gives you coding assistance with child-safe language.

Guided Skill Creation

You don't need to be technical to create your own skills. Meggy includes three system skills that guide you through the process:

Just say "I want to create a new skill" or "Save this as a skill" and Meggy will walk you through it.

Context-Aware Router

Not every skill is injected into every conversation — that would waste tokens and confuse the AI. The skill router analyzes each incoming message and selects only the most relevant skills:

  1. Quick relevance check — A lightweight model scores how relevant each active skill is to your current message
  2. Relevance filtering — Skills below the relevance threshold are excluded
  3. Compression — Long skill instructions are compressed to fit within the conversation's context budget
  4. Context delivery — Selected skills are seamlessly woven into the conversation context

For example, if you ask about cooking, your meal planner and recipe finder skills kick in. If you ask about your kid's homework, the education skills activate. The selection happens automatically — you don't have to do anything.

Skill Lifecycle

Skills go through a managed lifecycle:

  1. Acquisition — Created by the user, taught by conversation, imported from a web URL or local folder, or self-researched by the AI
  2. Danger analysis — A fast model evaluates the skill for potential harm or manipulation
  3. Activation — Moved from draft or dormant to active status
  4. Injection — The router dynamically selects and injects the skill into relevant conversations
  5. Quarantine — If flagged as dangerous, the skill is quarantined and requires manual review

AI-Callable Skill Tools

The AI can manage its own skills during conversations:

This self-modification capability means Meggy can learn and adapt its behavior over time based on your preferences and workflows. The more you use it, the better it gets at understanding how you work.

Skill Quality & Evaluation

How do you know if a skill is actually helping? Meggy tracks skill performance automatically and surfaces the results so you can make informed decisions.

Quality Scoring

Every active skill gets a quality score from 0 to 100, based on four signals:

Scores update automatically as you use Meggy. You can see the current score for any skill in its detail view.

A/B Comparison

Want proof that a skill makes a difference? Run an A/B comparison — Meggy sends the same prompts with and without the skill enabled, then judges which responses are better. You get a clear winner verdict with a confidence score.

Regression Alerts

Meggy runs a background check every 24 hours looking for skills whose quality is declining. If a skill's score drops significantly or users start stripping it out of conversations, you'll see an alert in Settings → Skills with the severity and possible causes.

You can dismiss the alert, re-evaluate the skill, or quarantine it until you've had time to investigate.
