# Claude Code - New Runtime

A New Runtime topic hub collecting signals, patterns, field notes, and public sources about claude code.

## Short Answer

- Claude Code is tracked here as an evidence-linked topic, not as a static glossary entry.
- The page connects raw observations to pattern hypotheses, longer analysis, and public sources.
- Use it as the canonical landing page before drilling into individual records.

## Patterns


## Field Notes

- [Claude Code Subagents Split Memory Instead of Inflating One Session](https://newruntime.com/posts/claude-code-subagents-memory/): Claude Code subagents show a practical form of agent memory hygiene: move noisy work into a separate context and return only the compressed result to the main session.
- [Claude HUD Turns Agent Observability into a Status Bar](https://newruntime.com/posts/claude-hud-agent-observability/): Claude HUD shows that agent observability can begin as a small status line for context health, tools, running agents, and progress instead of a large dashboard.
- [Long-Running Loops Need Goals, Not Keep-Going Prompts](https://newruntime.com/posts/claude-code-long-running-loops/): Long-running agent work is useful only with a testable goal, checkpoints, a terminal condition, and recovery policy; otherwise the loop becomes expensive blind continuation.
