What problem does it solve? Adding a new government or public data API to the Data Israel agent network requires touching many files—API clients, Mastra tools, agent factories, registries, translations, CSS badges, and tests. This Skill guides the full process so nothing is missed and every module follows the project's DataSourceDefinition pattern. ## Core Features & Use Cases - Structured Requirements Gathering: Walks through grouped questions covering API identity, authentication, architecture pattern (standalone vs. subfolder), agent delegation, and tool definitions. - Proxy Tier Classification: Runs a classification script against the upstream API from a non-Israeli egress to decide whether Bright Data residential or Web Unlocker proxying is required. - OpenSpec Proposal Scaffolding: Creates proposal.md, design.md, tasks.md, and spec files under openspec/changes/ before any code is written. - End-to-End Implementation & Registration: Generates the API client, Zod-schema tools, Hebrew agent instructions, translations, registry wiring, and API validation contract tests. - Use Case: You want to add a transportation data API to the platform. The Skill interviews you about the endpoint, classifies its proxy needs, drafts the OpenSpec change, implements all files, registers the agent, and verifies with tsc, build, and live API tests. ## Quick Start Ask the agent to add a new data source for the Israeli public transportation API and follow its guided workflow.
