# Guides NeuraWeave answers questions about coding agents and their context. We build Perpetuity, a memory proxy for coding agents. It is in early access. - [Can I run Claude Code through a proxy?](https://www.neuraweave.ai/guides/claude-code-proxy.md): Claude Code sends its requests to ANTHROPIC_BASE_URL. How proxy routing works, what a proxy sees, what breaks, and how your login and billing change. Updated 2026-10-23. - [Claude usage limit reached: what are my options?](https://www.neuraweave.ai/guides/claude-usage-limit-reached.md): Hit a Claude session, weekly or Opus limit? Wait for the reset, keep going on usage credits, upgrade or switch models, and pace the next week. Updated 2026-10-23. - [How do I make Claude Code remember between sessions?](https://www.neuraweave.ai/guides/claude-code-memory-between-sessions.md): What CLAUDE.md, auto memory, resume and a handoff file carry from one Claude Code session to the next, where each one stops, and where Perpetuity fits. Updated 2026-10-23. - [What does Claude Code forget when it compacts?](https://www.neuraweave.ai/guides/claude-code-compaction.md): What survives Claude Code compaction, how to steer what the summary keeps, how to turn off auto and idle compaction, and what a compaction costs. Updated 2026-10-23. - [What is filling my Claude Code context window?](https://www.neuraweave.ai/guides/claude-code-context-window.md): What fills a Claude Code context window, how to read /context, and how to trim CLAUDE.md, MCP and conversation history. Updated 2026-10-23. - [Which kind of memory should a coding agent use?](https://www.neuraweave.ai/guides/coding-agent-memory.md): What files, model-extracted notes, vector stores and a proxy each do as coding agent memory, and when each fits. From the team building Perpetuity. Updated 2026-10-23. - [Why does a long Claude Code session cost so much on the API?](https://www.neuraweave.ai/guides/claude-code-session-cost.md): Why Claude Code's API cost per prompt climbs in a long session, how to measure, cap and cut it, and what our measured long sessions cost. Updated 2026-10-23. - [Why does Claude Code get worse the longer a session runs?](https://www.neuraweave.ai/guides/claude-code-context-rot.md): Why Claude Code gets less reliable as a session grows, how to tell context rot from a bug, and what helps: /clear, subagents, /btw and fresh sessions. Updated 2026-10-23. - [Why does Codex forget what it was doing after compaction?](https://www.neuraweave.ai/guides/codex-compaction.md): Why Codex can lose its goal or its edits after auto-compaction, how to keep a plan it re-reads, and why AGENTS.md stops at 32 KiB by default. Updated 2026-10-23. - [Why does my first Claude Code message after a break use so much?](https://www.neuraweave.ai/guides/claude-code-cache-miss.md): Claude Code's prompt cache lasts 5 minutes or 1 hour. After a longer break the next message reprocesses your whole context. How to set and check the TTL. Updated 2026-10-23. - [Why is my Claude Code usage running out so fast?](https://www.neuraweave.ai/guides/claude-usage-running-out.md): Why Claude Code drains a plan's 5-hour and weekly usage, how to see what uses it, and the habits that cut it, with Anthropic's docs as sources.
