 ## What It Does
 
-This plugin automatically optimizes token usage by identifying and removing redundant or obsolete tool outputs from your conversation history. It operates in two modes:
-
-### Pruning Modes
-
-**Auto Mode** (`"auto"`): Fast, deterministic duplicate removal
-- Removes duplicate tool calls (same tool + identical parameters)
-- Keeps only the most recent occurrence of each duplicate
-- Zero LLM inference costs
-- Instant, predictable results
-
-**Smart Mode** (`"smart"`): Comprehensive intelligent pruning (recommended)
-- Phase 1: Automatic duplicate removal (same as auto mode)
-- Phase 2: AI analysis to identify obsolete outputs (superseded information, dead-end exploration, etc.)
-- Maximum token savings
-- Small LLM cost for analysis (reduced by deduplication first)
-
-When your session becomes idle, the plugin analyzes your conversation and prunes tool outputs that are no longer relevant, saving tokens and reducing costs.

 ## Configuration
@@ -76,91 +62,16 @@ Example configuration:
 
 The global config is automatically created on first run. Create project configs manually to override settings per-project:
 
-```bash
-mkdir -p .opencode
-cat > .opencode/dcp.jsonc << 'EOF'
-{
-  "debug": true,
-  "pruningMode": "auto"
-}
-EOF
-```
-
 After modifying configuration, restart OpenCode for changes to take effect.
 
-### Choosing a Pruning Mode
-
-**Use Auto Mode (`"auto"`) when:**
-- Minimizing costs is critical (zero LLM inference for pruning)
-- You have many repetitive tool calls (file re-reads, repeated commands)
-- You want predictable, deterministic behavior
-- You're debugging or testing and need consistent results
-
-**Use Smart Mode (`"smart"`) when:**
-- You want maximum token savings (recommended for most users)
-- Your workflow has both duplicates and obsolete exploration
-- You're willing to incur small LLM costs for comprehensive pruning
-- You want the plugin to intelligently identify superseded information

 ### Version Pinning
 
 If you want to ensure a specific version is always used or update your version, you can pin it in your config:
 
 ```json
 {
   "plugin": [
-    "@tarquinen/opencode-dcp@0.2.7"
+    "@tarquinen/opencode-dcp@0.3.10"
   ]
 }
