Best Claude Code memory tools

Track context-window usage and growth per turn to decide when to tidy up context.

Keeps a long-running agent's working notes through every compaction: briefs the summarizer, re-attaches the notes after the summary, and shows them in a panel you can steer.

CodeCraft is a free, open-source Claude Code mod that redraws the interface as a Minecraft-style HUD. Hearts represent the context window, hunger represents usage limits, armor represents work safety, and it adds a hotbar of items, villager subagents, and 60 achievements.

lcm is shared memory infrastructure for coding agents, replacing sliding-window forgetting with a persistent runtime for humans and agents, with SQLite persistence, DAG summaries and cross-session memory.

Claude Code mod that skips Claude re-reading a file it already read in the same conversation when the file's size and modification time have not changed, while allowing deliberate retries, different ranges, subagents, and post-/compact or /clear reads through.

Bash memory rules: Node commands run in claude-cmd.slice, and runs that would starve the machine are refused

Kindex is a local knowledge-graph MCP plugin and CLI for multiple agents; claude_modern is an experimental modern adapter with repository-local persistence, secret minimization and optional modern/legacy hooks.

A Claude Code plugin that measures how much context each Bash command consumed and, past a size limit, tells the model which narrower command would have answered the same question.

A Reddit submission introducing "Context Diet", a Claude Code mod intended to prevent large tool outputs from flooding the context window. The post text only contains submission metadata (author, subreddit, link/comments placeholders) with no repository link, installation steps or demo media, so the mod cannot be verified from the source alone.

Renders the context window as a brain: tool calls light up the corresponding regions, higher usage makes it more crowded, and compaction triggers sleep-like cleanup.

A Claude Code function-hooks plugin. When the main conversation has been idle for idleMinutes (default 50 minutes), it compacts before the prompt cache expires and passes AGENTS.md's Compact Instructions to every compact. It skips running turns, conversations below minMessageTokens, and cases beyond cutoffMinutes, leaving the reason in the transcript.

A Claude Code plugin that adds `/compact micro`, a manual compaction mode which locally elides Read tool results (including images and PDFs) and strips thinking blocks while keeping the rest of the transcript intact.
