Community Resource: 14-Phase Architectural Dissection of copilot-sdk

[SufficientDaikon]

Hey everyone,

I created an interactive documentation site that does a deep architectural analysis of the copilot-sdk codebase. It covers all 4 SDK implementations (TypeScript, Python, Go, C#) across 14 phases.

Live site: https://copilot-sdk-dissection.pages.dev
Source: https://github.com/SufficientDaikon/copilot-sdk-dissection

What it covers

Phase	Topic
01	Discovery -- project identity, repo signals
02	Structure -- directory layout, module dependencies
03	Tech Stack -- languages, build tools, IPC architecture
04	Entry Points -- bootstrap sequences, cross-SDK API table
05	Architecture -- 7 design patterns, state machines
06	Data Flow -- JSON-RPC flows, sessions, events, tool execution
07	API Surface -- public API, method signatures, extension points
08	Conventions -- naming, error handling, async patterns
09	Testing -- test harness, snapshot system, E2E architecture
10	Build and Deploy -- CI/CD pipelines, publishing
11	Dependencies -- runtime + dev dependency analysis
12	Security -- trust boundaries, auth flow, attack surface
13	Contribution -- code generation pipeline, dev workflows

Features

• 87 Mermaid.js diagrams (flowcharts, sequence diagrams, state machines)
• Syntax-highlighted code across all 4 languages
• Dark theme with WCAG AA compliance
• Zero build step -- pure static HTML/CSS/JS
• Prev/next navigation for sequential reading

Hope this is useful for anyone building integrations with the SDK or just curious about how it works. Feedback welcome!
