Implement AI-powered Web3 agent platform with CI/CD and Copilot integration by Copilot · Pull Request #3 · lippytm/Web3AI

Copilot · 2025-12-13T23:21:50Z

Transforms empty repository into production-ready Web3 AI platform with LangChain agents, automated workflows, and developer tooling.

AI Agent Framework

LangChain + OpenAI GPT-4 integration for blockchain intelligence
BaseAgent foundation with extensible task execution and context management
BlockchainAnalysisAgent for on-chain analysis (addresses, gas prices, transaction patterns)
SmartContractAgent for contract interaction and security assessment
Web3Provider service wrapping ethers.js v6 for multi-chain EVM operations

// Analyze blockchain data with AI
const provider = new Web3Provider(rpcUrl, chainId);
const agent = new BlockchainAnalysisAgent(apiKey, provider);
const analysis = await agent.analyzeAddress('0x...');
console.log(analysis.result, analysis.confidence);

CI/CD Pipeline

GitHub Actions workflow with:

Parallel lint/test jobs (Node 18, 20)
TypeScript compilation with artifact upload
Security scanning (npm audit, Snyk)
Explicit GITHUB_TOKEN permissions (CodeQL verified)

GitHub Copilot Configuration

.github/copilot-instructions.md defines:

Web3-specific patterns (address validation, gas estimation)
AI agent development conventions (context injection, confirmation flows)
Security requirements (input sanitization, rate limiting)

TypeScript Infrastructure

ES2022 modules with strict mode
Jest with ts-jest/presets/default-esm for proper ESM support
ESLint configured for type-aware linting
Main module detection using pathToFileURL for correct URL comparison

Documentation

README: setup, architecture, Copilot workflow
AI_FEATURES.md: agent capabilities and best practices
CI_CD.md: pipeline configuration
EXAMPLES.md: 10 practical usage patterns
CONTRIBUTING.md: development workflow

.github/workflows/ci.yml

+      - name: Install dependencies
+        run: npm ci
+


This workflow uses npm ci, but the repository does not include a package-lock.json. npm ci will fail without a lockfile, breaking the test job.

Either commit a lockfile (recommended) or switch this step to npm install.

+  private chainId: number;
+
+  constructor(rpcUrl: string, chainId: number) {
+    this.provider = new ethers.JsonRpcProvider(rpcUrl);
+    this.chainId = chainId;


chainId is stored but never used to configure the underlying ethers provider. This can also trigger @typescript-eslint/no-unused-vars on the private field, failing lint.

Either pass chainId into the ethers.JsonRpcProvider constructor (so the provider is network-pinned) or remove the field if it’s not needed.

Suggested change

private chainId: number;

constructor(rpcUrl: string, chainId: number) {

this.provider = new ethers.JsonRpcProvider(rpcUrl);

this.chainId = chainId;

constructor(rpcUrl: string, chainId: number) {

this.provider = new ethers.JsonRpcProvider(rpcUrl);

+import { logger, LogLevel } from '../utils/logger.js';


LogLevel is imported but never used, which will fail the configured @typescript-eslint/no-unused-vars rule.

Remove the unused import (or use it to set the logger level within the test).

Suggested change

import { logger, LogLevel } from '../utils/logger.js';

import { logger } from '../utils/logger.js';

src/__tests__/logger.test.ts

+  it('should log debug messages', () => {
+    logger.debug('Test debug message');
+    expect(consoleSpy.debug).toHaveBeenCalledWith('[DEBUG] Test debug message');


This test expects debug logs to be emitted, but the exported logger instance defaults to LogLevel.INFO, so logger.debug(...) should be a no-op and console.debug will not be called.

To make this test valid, either (a) allow the logger level to be configured in tests (e.g., export the Logger class or add a setter) and set it to DEBUG, or (b) change the expectation to reflect the default INFO behavior.

Suggested change

it('should log debug messages', () => {

logger.debug('Test debug message');

expect(consoleSpy.debug).toHaveBeenCalledWith('[DEBUG] Test debug message');

it('should not log debug messages when level is INFO by default', () => {

logger.debug('Test debug message');

expect(consoleSpy.debug).not.toHaveBeenCalled();

+      case 'transaction':
+        if (!query.txHash) throw new Error('Transaction hash required');
+        return this.getTransaction(query.txHash);
+


BlockchainQuery.type includes 'contract', but executeQuery does not handle it and will throw Unsupported query type: contract. This is a functional mismatch between the public type and implementation.

Either implement the 'contract' branch (using contractAddress/method/params) or remove 'contract' from the BlockchainQuery union so callers can’t request an unsupported query.

Suggested change

case 'contract':

if (!('contractAddress' in query) || !query.contractAddress) {

throw new Error('Contract address required for contract query');

}

if (!('abi' in query) || !query.abi) {

throw new Error('Contract ABI required for contract query');

}

if (!('method' in query) || !query.method) {

throw new Error('Contract method required for contract query');

}

// Normalize params to an array

const params = Array.isArray((query as any).params)

? (query as any).params

: ((query as any).params != null ? [(query as any).params] : []);

const contract = new ethers.Contract(query.contractAddress as string, (query as any).abi, this.provider);

// Dynamically call the specified method with provided params

const contractAny = contract as any;

if (typeof contractAny[query.method] !== 'function') {

throw new Error(`Method ${String(query.method)} not found on contract`);

}

return contractAny[query.method](...params);

package.json

+    "lint": "eslint src/**/*.ts",
+    "lint:fix": "eslint src/**/*.ts --fix",


The lint script runs ESLint on src/**/*.ts, which includes *.test.ts files under src/__tests__. However, parserOptions.project points at tsconfig.json, and that tsconfig excludes **/*.test.ts, which commonly causes @typescript-eslint/parser to error that the file is not included in the project.

Either adjust the lint globs to exclude tests, or add a separate tsconfig.eslint.json that includes tests and reference that from ESLint.

Suggested change

"lint": "eslint src/**/*.ts",

"lint:fix": "eslint src/**/*.ts --fix",

"lint": "eslint src/**/*.ts --ignore-pattern '**/*.test.ts'",

"lint:fix": "eslint src/**/*.ts --ignore-pattern '**/*.test.ts' --fix",

package.json

+    "langchain": "^0.1.0",
+    "web3": "^4.3.0"


web3 is listed as a runtime dependency but appears unused in the TypeScript sources. Keeping unused Web3 libraries increases install size and supply-chain surface area.

Consider removing web3 from dependencies unless it’s needed for upcoming work.

Suggested change

"langchain": "^0.1.0",

"web3": "^4.3.0"

"langchain": "^0.1.0"
