claudecode-source (annotated bundle)
Summary
Packages a deep source-level analysis of a Claude Code snapshot (~1,900 files) with HTML reports, architecture visuals, and walkthrough guides, plus an independently written source-analysis report in Chinese and English. One of the most complete single bundles for studying the tool definitions, main agent loop, and edit-validation path.
Key Takeaways
- Study the tool definition modules to see how schemas constrain model behavior
- The main loop folds tool results back into context in a strict sequence
- Edits are validated (read-before-write, diff checks) before hitting disk
Reliability Note
Independent reverse-engineering effort - unofficial, verify against official Anthropic docs and behavior.

Design a Single-Loop Agent
Build the core agent loop the leading coding agents use: one model, one loop, tools in, results folded back into context.

Add a Plan/Todo System to Your Agent
Give your agent the planning discipline of the leading harnesses: an explicit, model-visible todo list that survives long tasks.

Design Tool Schemas for Agents
Write tool schemas that constrain model behavior: tight types, enums over strings, and parameters that make misuse hard.

Tool Result Size Management
Stop tool outputs from flooding context: budgets per tool, smart truncation, pagination, and reference-based results.

Verification Loops: Never Trust an Unrun Edit
Wire verification into your agent so every edit is checked by machines - syntax, tests, behavior - before it counts as done.
