-The Working Memory Plugin provides persistent core_memory blocks. **USE THEM CORRECTLY**:
-
-## goal block (1000 chars)
-**Purpose**: ONE specific task you're working on RIGHT NOW
-
-✅ **GOOD Examples**:
-- "Fix pruning bug where items with relevanceScore <0.01 are incorrectly excluded"
-- "Add new tool: working_memory_search to query pool items by keyword"
-- "Investigate why pressure warnings not showing in system prompt"
-
-❌ **BAD Examples**:
-- "Complete Phase 1-4 development and testing" (too broad, likely already done)
-- "Build a working memory system for OpenCode" (project-level goal, not task-level)
-
-## progress block (2000 chars)
-**Purpose**: Checklist of done/in-progress/blocked items + key decisions
-
-✅ **GOOD Examples**:
-- "✅ Found bug in applyDecay() line 856\\n⏳ Testing fix with gamma=0.85\\n❓ Need to verify edge case: score=0"
-- "✅ Phase 1-3 complete\\n⏳ Phase 4 intervention testing\\n⚠️ BLOCKED: Need promptAsync docs"
-
-❌ **BAD Examples**:
-- "Function sendPressureInterventionMessage() @ working-memory.ts:L1286-1354" (line numbers useless after edits)
-- "Commit 2f42f1b implemented promptAsync integration" (commit hash irrelevant)
-- "API: client.session.promptAsync({ path: {id}, body: {...} })" (API signature, not progress)
-

-- "Key paths: .opencode/memory-core/ (persistent blocks), memory-working/ (session data)"
-- "Pattern: All async file ops use mkdir({recursive:true}) before writeFile"
-
-❌ **BAD Examples**:
-- "OpenCode SDK types: TextPartInput = { type: 'text', text: string, synthetic?: boolean }" (type definition)
-- "Function signature: async function loadCoreMemory(directory: string, sessionID: string): Promise<CoreMemory | null>" (function signature)
-- "Method client.session.promptAsync() returns 204 No Content" (API behavior, read docs instead)

-## ⚠️ NEVER Store in Core Memory
-- API documentation (read source/docs when needed)
-- Type definitions from libraries (import them)

-- Implementation details (belong in code comments)
-- Completed goals (clear them immediately)
