Dynamic Context Pruning
Dynamic Context Pruning (DCP) automatically reduces token usage in OpenCode by managing conversation context. It is a community plugin, originally by @Tarquinen and now maintained under the Opencode-DCP org.
Project status
Development on DCP has slowed because most new context-management work has moved to Sleev and the sleev CLI — a local proxy for Claude Code, Codex, and OpenCode that builds on DCP’s core ideas. DCP remains available for OpenCode plugin users; if you are starting fresh, the upstream README recommends trying Sleev (npm i -g sleev).
Key features
| Feature | Description |
|---|---|
| Compress tool | Exposed to the model; replaces closed, stale conversation content with high-fidelity technical summaries |
| Model-chosen timing | The model picks when to compress based on task completion, instead of static triggers on maximum context |
| Selective scope | Compresses only the specific messages no longer needed verbatim |
| Automatic cleanup | Prunes obsolete tool outputs from context |
| History untouched | Session history is never modified — placeholders are substituted before requests reach your LLM |
Installation
Install from the CLI (installs the package and adds it to your global OpenCode config):
opencode plugin @tarquinen/opencode-dcp@latest --globalHow it works
DCP reduces context size through the compress tool and automatic cleanup. Instead of triggering statically when a session reaches maximum context across the entire session — as OpenCode’s built-in compaction does — Compress lets the model activate on task completion and target only the messages that are no longer needed verbatim.
