Automatically reduces token usage in OpenCode by removing obsolete tool outputs from conversation history.
Add to your OpenCode config:
When a new version is available, DCP will show a toast notification. Update by changing the version number in your config.
Restart OpenCode. The plugin will automatically start optimizing your sessions.
DCP implements two complementary strategies:
Deduplication — Fast, zero-cost pruning that identifies repeated tool calls (e.g., reading the same file multiple times) and keeps only the most recent output. Runs instantly with no LLM calls.
AI Analysis — Uses a language model to semantically analyze conversation context and identify tool outputs that are no longer relevant to the current task. More thorough but incurs LLM cost.
DCP is non-destructive—pruning state is kept in memory only. When requests go to your LLM, DCP replaces pruned outputs with a placeholder; original session data stays intact.
DCP uses its own config file (~/.config/opencode/dcp.jsonc or .opencode/dcp.jsonc), created automatically on first run.

}Settings are merged in order: Defaults → Global (~/.config/opencode/dcp.jsonc) → Project (.opencode/dcp.jsonc). Each level overrides the previous, so project settings take priority over global, which takes priority over defaults.
Restart OpenCode after making config changes.
