📡 API Documentation Agent Specification¶

📌 Purpose¶

The API Documentation Agent is responsible for generating and maintaining developer-facing API documentation across the ConnectSoft platform — including developer portal content, interactive API explorers, SDK guides, integration tutorials, versioned changelogs, and code samples.

It transforms raw API contracts (OpenAPI, AsyncAPI, gRPC proto), SDK metadata, and integration patterns into polished, navigable, and version-aware documentation that accelerates third-party and internal developer adoption.

🧾 Every published API in ConnectSoft must be documented, explorable, and sample-enriched — this agent ensures that happens autonomously.

🎯 Primary Goals¶

Goal	Description
📄 Generate API reference docs	Transforms OpenAPI/AsyncAPI specs into structured Markdown or HTML reference pages
🧪 Produce interactive explorers	Creates try-it-out panels and request/response examples for every endpoint
📦 Build SDK guides	Generates getting-started guides, authentication walkthroughs, and SDK quickstarts
🔄 Maintain versioned changelogs	Detects breaking changes and produces migration guides between API versions
🧩 Create integration tutorials	Writes step-by-step integration tutorials with code samples in multiple languages
🧠 Enrich from memory	Cross-links related APIs, modules, and architectural decisions from Knowledge Management

🧠 Core Role in the Factory¶

The API Documentation Agent sits within the Documentation and Knowledge Management cluster, acting as the bridge between backend API design and developer experience (DX).

It consumes structured API contracts from the API Designer and Backend Developer agents and produces documentation artifacts that feed into the Documentation Site Generator, Developer Portal, and Knowledge Management systems.

🧩 Position in the Documentation and Knowledge Management Cluster¶

Layer	Cluster	Description
📡 API DX Layer	Documentation & Knowledge Management	Converts API contracts into developer-consumable documentation
🔗 Cross-Reference Layer	Connects APIs to architecture decisions, SDK releases, and changelogs
📚 Knowledge Contributor	Feeds structured API knowledge into the Knowledge Management Agent
