compaction

A Claude Code mod that warns when the context window fills up and suggests saving the session's decisions with `/save-context` before automatic compaction summarises them away.

Hands a long session off cleanly: at a context threshold Claude updates the docs and writes a handoff, the session compacts with its instructions, then a kickoff prompt carries on. Gives Claude a live context reading and a /wrap-up skill

Shows how long the prompt cache stays warm and suggests compacting a large context at the moments where it pays off.

Claude Code plugin that compresses tool output, checkpoints before compaction, scores context quality, and reports token/cost savings on a local dashboard; ships hooks and a localhost daemon.

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.

When context usage reaches a threshold you set, write a handover note first, then compact automatically, and hand the note to whoever continues: this conversation after compaction, and the next session in the same project.

A Claude Code plugin that keeps notes you pin with `/pin-note` for the whole session and re-injects them verbatim into the model's context after each compaction and `/clear`, via a SessionStart hook, with per-session persistence in `$.store` and an off-by-default toggle.

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.

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.

A Claude Code mod that replaces compaction with a structured handoff: a fork of the session writes the handoff from the prompt cache, and the conversation continues from exactly that handoff.

conPACT is a Claude Code mod that automatically compacts a session's context after a task finishes via an MCP tool, and prompts to compact idle sessions before the prompt cache expires. It ships as an in-process plugin hooks mod in Claude Code 2.1.284+, with a Stop hook fallback over Remote Control, and also supports Codex/ChatGPT Desktop. Author reports ~4.7% spend savings and lower peak context, MIT licensed.

A Claude Code plugin that defers auto-compaction until the turn ends and summarizes at its own configurable effort level, preserving the prompt cache.
