This registry enables agents to dynamically discover and compose skills, replacing hardcoded tool chains with declarative workflows. The system supports semantic versioning, metadata schemas, and composite weapons for exponential capability growth.", "body_md": "FROST Five-Dimensional Meta-Model Series · Part 1\n\nImagine you have an Agent. It's smart—it can write code, analyze data, search for information.\n\nBut when you ask it: \"Help me build a crawler to scrape e-commerce prices and analyze trends,\" it freezes.\n\nNot because it can't, but because it **can't find** what it knows.\n\nIt has a bunch of skills scattered across the codebase, but no unified place telling it: \"You know these things, use them as needed.\"\n\nThis is the common problem with current Agent frameworks: **skills exist, but they're unorganized.**\n\nIn FROST V4.1, we introduced the **Weapon Registry**.\n\nA **Weapon** is not a traditional \"tool\" or \"function\"—it's:\n\nA discoverable, composable, versionable skill unit.\n\nThink of it this way:\n\n``` python\nfrom core.armory import Armory\n\n# Create a weapon registry\narmory = Armory()\n\n# Register a weapon\narmory.register(\n    name=\"web_scraper\",\n    version=\"1.0.0\",\n    skill=WebScraperSkill(),\n    metadata={\n        \"category\": \"data_collection\",\n        \"description\": \"Scrape web data\",\n        \"input_schema\": {\"url\": \"str\", \"selector\": \"str\"},\n        \"output_schema\": {\"data\": \"list[dict]\"},\n    }\n)\n\n# Register another one\narmory.register(\n    name=\"trend_analyzer\",\n    version=\"1.0.0\",\n    skill=TrendAnalyzerSkill(),\n    metadata={\n        \"category\": \"analysis\",\n        \"description\": \"Analyze data trends\",\n        \"input_schema\": {\"data\": \"list[dict]\"},\n        \"output_schema\": {\"trend\": \"str\", \"confidence\": \"float\"},\n    }\n)\n```\n\nEvery weapon has:\n\n`web_scraper`\n\n, no conflicts with other skills`1.0.0`\n\n, supports upgrades and rollbacks\n\n``` js\n# Find by category\ndata_skills = armory.find_by_category(\"data_collection\")\n# => [web_scraper, api_fetcher, file_parser, ...]\n\n# Find by capability (fuzzy match)\nrelevant = armory.find_by_capability(\"scrape web\")\n# => [web_scraper]\n\n# List all available weapons\nall_weapons = armory.list_all()\n# => [web_scraper, trend_analyzer, code_writer, ...]\n```\n\nAgents no longer need to hardcode \"what I can do\"—they **dynamically discover** which weapons they can use.\n\n```\n# Define a composite weapon\narmory.register_composite(\n    name=\"ecommerce_price_tracker\",\n    components=[\"web_scraper\", \"trend_analyzer\"],\n    description=\"E-commerce price tracking and trend analysis\",\n    workflow=\"\"\"\n    1. Use web_scraper to scrape price data\n    2. Pass data to trend_analyzer for analysis\n    3. Return analysis report\n    \"\"\"\n)\n\n# Use the composite weapon\nresult = agent.execute(\"ecommerce_price_tracker\", {\n    \"url\": \"https://example.com/product\",\n    \"selector\": \".price\"\n})\n```\n\n**Composite weapons** let Agent capabilities grow exponentially:\n\n| Dimension | Traditional Tool Calling | FROST Weapon Registry |\n|---|---|---|\n| Discovery | Hardcoded in source | Dynamic query, matched by need |\n| Versioning | None | Semantic versioning (1.0.0 → 1.1.0) |\n| Metadata | Simple function signatures | Full input/output schemas + categories + descriptions |\n| Composition | Manual glue code | Declarative composition, auto-generated workflows |\n| Testability | Need to mock entire tool chains | Each weapon tested independently, compositions also testable |\n\n**Key difference:** The Weapon Registry makes skills **first-class citizens**, not just appendages to code.\n\nSuppose you want to build an **automated competitor analysis Agent**:\n\n``` python\n# Hardcode all steps\nclass CompetitorAnalyzer:\n    def __init__(self):\n        self.scraper = WebScraper()  # Hard dependency\n        self.analyzer = TrendAnalyzer()  # Hard dependency\n        self.reporter = ReportGenerator()  # Hard dependency\n\n    def analyze(self, competitor_url):\n        data = self.scraper.scrape(competitor_url)\n        trend = self.analyzer.analyze(data)\n        report = self.reporter.generate(trend)\n        return report\n```\n\nProblems:\n\n```\n# Declarative composition\nagent = Agent(armory=armory)\n\n# Agent decides which weapons to use\nresult = agent.execute(\"competitive_analysis\", {\n    \"competitor\": \"https://competitor.com\",\n    \"metrics\": [\"price\", \"features\", \"reviews\"]\n})\n\n# Agent's internal logic (automatic):\n# 1. Query armory.find_by_capability(\"scrape web\") → select web_scraper\n# 2. Query armory.find_by_capability(\"analyze trends\") → select trend_analyzer\n# 3. Query armory.find_by_capability(\"generate report\") → select report_generator\n# 4. Compose and execute, return result\n```\n\nAdvantages:\n\nThis is FROST's design philosophy:\n\nTools are passive; weapons are active.\n\nIn FROST's family governance model:\n\nThe Weapon Registry makes this process **auditable, controllable, and evolvable**.\n\nWeapons solve \"what Agent can do.\"\n\nBut how do Agents **collaborate**? How do they know \"task completed,\" \"error occurred,\" \"need help\"?\n\nThe answer is **Event**—Agent's nervous system.\n\n**Next article preview:** *Event: Teaching Agents to \"Shout Out\"*\n\n*FROST: Giving agents lineage, memory, and honor.*", "url": "https://wpnews.pro/news/weapon-give-your-agent-a-real-skill-arsenal", "canonical_source": "https://dev.to/llimage/weapon-give-your-agent-a-real-skill-arsenal-1cl3", "published_at": "2026-06-28 10:50:01+00:00", "updated_at": "2026-06-28 11:33:38.923895+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "machine-learning"], "entities": ["FROST", "Weapon Registry", "Armory"], "alternates": {"html": "https://wpnews.pro/news/weapon-give-your-agent-a-real-skill-arsenal", "markdown": "https://wpnews.pro/news/weapon-give-your-agent-a-real-skill-arsenal.md", "text": "https://wpnews.pro/news/weapon-give-your-agent-a-real-skill-arsenal.txt", "jsonld": "https://wpnews.pro/news/weapon-give-your-agent-a-real-skill-arsenal.jsonld"}}
