Feature: EA Autonomous Agent

[wilson-cl]

Summary

Introduces the EA Scaffolding Agent — an AI-powered tool that automates the creation of Chainlink External Adapters from YAML specifications.

What's Included

Core Agent (ea-agent/)

• src/agent.py — Main orchestrator that runs a 3-phase workflow:
  1. EA Developer scaffolds the adapter
  2. Integration Test Writer/Validator loop (3 approvals required)
  3. Unit Test Writer/Validator loop (3 approvals required)
• package-template/ — Complete EA scaffold with endpoints, transports, and test structure
• requests/ — Directory for YAML requirement files
• README.md — Documentation for local, Cursor, and CI usage

Agent Prompts (.claude/agents/)

• ea_developer.md — Scaffolds adapter code from YAML specs
• ea_integration_test_writer.md — Writes integration tests
• ea_integration_test_validator.md — Validates integration tests
• ea_unit_test_writer.md — Writes unit tests
• ea_unit_test_validator.md — Validates unit tests

CI/CD (.github/workflows/)

• generate-ea.yml — Triggers on PRs with YAML files in ea-agent/requests/ or via /generate-ea comment

Usage

Local:

uv run ea-agent/src/agent.py ea-agent/requests/OPDATA-123-my-adapter.yaml

Cursor: Reference agent prompts with @ea_developer.md, etc.

CI: Add a YAML file to ea-agent/requests/ and open a PR, or comment /generate-ea

Output

Generated adapter packages are created at packages/sources/<adapter-name>/ with complete source code, tests, and configuration.
