+# Integration Guide: Claude Code Patterns
+
+This guide documents how to integrate the Claude Code–inspired features
+into the existing Modular Patchbay pipeline. Each section identifies
+the current integration point, the adapter to use, and a migration path.
+
+---
+

+
+   Phase 1 Features (standalone, zero modifications to existing code)
+```
+
+---
+
+## 1. System Prompt Building
+
+**Current code:** `src/services/systemFrameBuilder.ts` (line ~68)
+
+The existing `buildSystemFrame()` and `buildSystemFrameOptimized()`
+assemble identity, instructions, constraints, workflow, and tool guide
+sections by reading from `useConsoleStore`. Sections are emitted as XML tags.
+
+**Lightweight adapter:** `src/adapters/systemPromptAdapter.ts`
+
+`buildCacheOptimizedPrompt()` provides a simple function interface that
+automatically separates static sections (role, tools, instructions) from
+dynamic sections (memory, context, conversation state) for optimal prompt
+caching. Returns a cache breakpoint character index.
+
+**Deep integration:** `src/services/systemFrameBuilderAdapter.ts`
+
+`buildSystemFrameWithBuilder()` is the full-fidelity adapter that maps
+all `SystemFrameInput` fields through SystemPromptBuilder. Already
+wired into `buildSystemFrame()`.
+
+**How to migrate:**
+
+```typescript
+// Before (manual string concatenation)
+const prompt = buildSystemFrame();
+
+// After (lightweight adapter)
+import { buildCacheOptimizedPrompt } from './adapters/systemPromptAdapter';
+const { fullText, cacheBreakpoint, staticTokens } = buildCacheOptimizedPrompt({
+  role: agentMeta.persona,
+  tools: toolGuide,
+  memory: memorySection,
+  context: contextSection,
+});
+```
+
+---
+
+## 2. Depth Packing / Context Assembly
+
+**Current code:** `src/graph/packer.ts` (line ~83)
+
+`packContext()` takes `TraversalResult` + `tokenBudget` and
+assigns depth levels (0–4) based on relevance scores. Uses `depthFilter`
+for tree-index-aware rendering.
+
+**Lightweight adapter:** `src/adapters/reactivePackerAdapter.ts`
+
+`withReactiveCompaction()` wraps any pack function with signal-driven
+depth adjustments. Feed in `ContextSignal[]` (token_pressure,
+hedging_detected, topic_shift, tool_heavy, error_recovery) to
+automatically adjust depths at runtime.
+
+**Deep integration:** `src/graph/reactivePackerWrapper.ts`
+
+The existing `withReactiveCompaction()` in `reactivePackerWrapper.ts`
+is already wired into `packContextReactive()` in `packer.ts` (line ~180).
+
+**How to migrate:**
+
+```typescript
+import { withReactiveCompaction } from './adapters/reactivePackerAdapter';
+
+const reactivePack = withReactiveCompaction(myPackFn, {
+  pressureThreshold: 0.75,
+});
+const result = reactivePack(files, budget, 'full', [
+  { type: 'token_pressure', ratio: 0.85 },
+]);
+```
+
+---
+
+## 3. Memory Persistence
+
+**Current code:** `server/routes/memory.ts`, `server/services/memoryScorer.ts`
+
+The server-side memory system uses SQLite-backed scoring. The frontend
+has `src/store/memoryStore.ts` (Zustand) and `src/services/memoryPipeline.ts`.
+
+**Lightweight adapter:** `src/adapters/memoryAdapter.ts`
+
+`getMemoryStore()` provides singleton filesystem-backed MemoryStore.
+`createMemoryContextSection()` generates a formatted section for injection
+into system prompts. `extractAndStoreMemories()` extracts memories from
+agent output using pattern-based MemoryExtractor.
+
+**Deep integration:** `src/services/memoryStoreIntegration.ts`
+
+Already wired into `contextAssembler.ts` via `assemblePipelineContextWithMemory()`.
+
+**How to migrate:**
+
+```typescript
+import { getMemoryStore, createMemoryContextSection } from './adapters/memoryAdapter';
+
+const memorySection = createMemoryContextSection(task, 2000);
+builder.addDynamic('memory', memorySection);
+
+// After agent run:
+import { extractAndStoreMemories } from './adapters/memoryAdapter';
+const count = extractAndStoreMemories(agentId, agentOutput);
+```
+
+---
+
+## 4. Conversation & Tool Output Compression
+
+**Current code:** `src/services/pipeline.ts` (line ~28)
+
+`createContextMiddleware` is imported and optionally applied during pipeline
+execution. Conversation history is in `src/services/pipelineChat.ts`.
+
+**Lightweight adapter:** `src/adapters/contextMiddleware.ts`
+
+Standalone functions:
+- `compressToolOutputs(calls)` — summarizes tool call sequences
+- `compressContext(content, type, maxTokens)` — generic compression
+- `createContextMiddleware(config)` — middleware factory
+
+**Deep integration:** `src/services/contextMiddleware.ts`
+
+Full middleware pipeline with `processToolCalls`, `collapseConversation`,
+`collapseCode`, and `collapse` dispatcher. Already imported in `pipeline.ts`.
+
+**How to migrate:**
+
+```typescript
+import { createContextMiddleware } from './adapters/contextMiddleware';
+
+const mw = createContextMiddleware({ maxToolTokens: 500 });
+const collapsed = mw.processToolOutput('bash', longOutput);
+const compressed = mw.processConversation(turns);
+```
+
+---
+
+## 5. Agent & Knowledge Search
+
+**Current code:** `server/services/agentStore.ts`, `server/routes/agents.ts`
+
+Agent discovery uses the registry (`src/store/registry.ts`) with simple name/tag filtering.
+
+**Lightweight adapter:** `src/adapters/searchAdapter.ts`
+
+`createAgentSearchService(agents, knowledge)` builds a TF-IDF index.
+`searchAgents(query)` and `searchKnowledge(query)` provide ranked results.
+
+**Deep integration:** `src/services/agentSearchIntegration.ts`
+
+Manages singleton with auto-reindex. `toSearchableAgent()` converts registry agents.
+
+**How to migrate:**
+
+```typescript
+import { createAgentSearchService, searchAgents } from './adapters/searchAdapter';
+
+createAgentSearchService(allAgents, allKnowledge);
+const matches = searchAgents('maritime expert', 3);
+```

+# Phase 2: Integration Report — Claude Code Patterns into Modular Patchbay
+
+**Branch:** `feat/claude-code-patterns`
+**Commit:** `37a8ede8b5dbde7f8ac879d60cbe1b910f0c8df1`
+**Date:** 2026-04-01
+
+## Architecture Analysis (Task 1)
+
+### Key Pipeline Files and Roles
+
+| File | Role |
+|------|------|
+| `src/services/contextAssembler.ts` | Main context assembly — builds system prompt with XML-tagged sections (identity, instructions, constraints, workflow, knowledge). Entry point: `assembleContext()` |
+| `src/services/systemFrameBuilder.ts` | Builds non-knowledge system prompt sections using Zustand stores. Entry point: `buildSystemFrame()` |
+| `src/services/pipeline.ts` | End-to-end context pipeline: Source → Tree Index → Navigation → Compression. Entry point: `runPipeline()` |
+| `src/services/pipelineChat.ts` | Chat pipeline with conversation management and memory stages |
+| `src/utils/depthFilter.ts` | Filters tree nodes by depth level (0=Full → 4=Mention). Used by packer |
+| `src/graph/packer.ts` | Budget-aware context packing — assigns depth by relevance, fits token budget. Entry point: `packContext()` |
+| `src/graph/types.ts` | Core types: `FileNode`, `TraversalResult`, `PackedContext`, `PackedItem` |
+| `server/services/agentRunner.ts` | Server-side agent execution loop with Claude Agent SDK |
+| `server/services/agentStore.ts` | Filesystem-based agent persistence with versioning |
+| `src/services/memoryPipeline.ts` | Pre-recall and post-write memory stages (existing, Zustand-backed) |
+| `src/services/budgetAllocator.ts` | Epistemic budget allocation across knowledge sources |
+| `src/store/registry.ts` | Marketplace registry for skills, MCP servers, and presets |
+
+### Integration Approach
+
+The existing codebase uses:
+- **Zustand stores** for state management (consoleStore, mcpStore, memoryStore)
+- **XML-tagged sections** for prompt structure (`<identity>`, `<instructions>`, etc.)
+- **Numeric depth levels** (0-4) in the packer/depthFilter
+- **Named depth levels** ('full'→'mention') in Phase 1's ReactiveCompaction
+
+Integration was done via **adapter/wrapper pattern** to avoid rewriting core code:
+- Each feature gets a dedicated adapter that bridges Phase 1 APIs with existing pipeline types
+- Adapters can be adopted incrementally without breaking existing code paths
+
+---
+
+## Files Created
+
+### Task 2: SystemPromptBuilder Integration
+**File:** `src/services/systemFrameBuilderAdapter.ts`
+
+Adapter that uses `SystemPromptBuilder` under the hood while providing the same `buildSystemFrame()` interface. Maps existing prompt sections into static (cacheable) and dynamic (volatile) regions with `__DYNAMIC_BOUNDARY__` marker for optimal prompt caching.
+
+- **Static:** identity, instructions, constraints, workflow, tools
+- **Dynamic:** memory, context, conversation state, provenance
+
+### Task 3: ReactiveCompaction Packer Wrapper
+**File:** `src/graph/reactivePackerWrapper.ts`
+
+`withReactiveCompaction()` wrapper that enhances `packContext()`:
+1. Runs standard `packContext()` first
+2. Generates context signals (token pressure, hedging, topic shift, tool-heavy, error recovery)
+3. Feeds signals to `ReactiveCompaction.processSignals()`
+4. Applies `DepthAdjustment` results back to packed items
+5. Handles numeric↔named depth level conversion between packer (0-4) and ReactiveCompaction ('full'→'mention')
+
+### Task 4: MemoryStore Integration
+**File:** `src/services/memoryStoreIntegration.ts`
+
+Bridges `MemoryStore` (filesystem-backed) with the context assembly pipeline:
+- `getMemoryStore()` — singleton factory
+- `createMemoryContextSection(query)` — searches memories, formats as dynamic prompt section
+- `extractAndStoreMemories(agentId, output)` — post-run memory extraction
+- `searchMemories()`, `consolidateMemories()` — utility functions
+
+Works alongside existing `memoryPipeline.ts` (Zustand-backed) without conflicts.
+
+### Task 5: ContextCollapse + ToolUseSummary Middleware
+**File:** `src/services/contextMiddleware.ts`
+
+`createContextMiddleware()` factory that produces a middleware pipeline:
+- `processToolCalls()` — summarizes tool call sequences via `ToolUseSummary`
+- `processConversation()` — collapses conversation history via `ContextCollapse`
+- `collapseToolOutput()`, `collapseCode()`, `collapse()` — individual collapse operations
+- Configurable token budgets per content type
+- Enable/disable flags for each processing stage
+
+### Task 6: AgentSearch Integration
+**File:** `src/services/agentSearchIntegration.ts`
+
+`createAgentSearchService()` that connects `AgentSearch` to agent management:
+- Indexes agents and knowledge sources with TF-IDF
+- Auto-detects index staleness via hash comparison
+- `reindex()` for manual refresh
+- `toSearchableAgent()` helper to convert registry entries to searchable format
+
+### Task 7: Barrel Export
+**File:** `src/claude-code-patterns/index.ts`
+
+Clean re-export of all 6 Phase 1 features plus all 5 integration adapters with full type exports.
+
+### Task 8: Integration Tests
+**File:** `tests/unit/claude-code-integration.test.ts`
+
+5 test suites covering:
+1. **SystemPromptBuilder + Pipeline** — static/dynamic boundary, XML tags, empty input
+2. **ReactiveCompaction + Packer** — token pressure adjustments, hedging upgrades, `withReactiveCompaction` wrapper
+3. **MemoryStore Round-Trip** — save → search → inject into context, extract from agent output
+4. **ContextMiddleware** — tool summarization, conversation collapse, disable flags
+5. **AgentSearch + Registry** — agent search by description, reindex on changes
+
+### Task 9: Main Exports
+The barrel export at `src/claude-code-patterns/index.ts` serves as the public API surface. No pre-existing `src/index.ts` was found to update — the project is a Vite app with `src/main.tsx` as entry point.
+
+---
+
+## Type Compatibility Notes
+
+| Phase 1 Type | Pipeline Type | Bridge |
+|---|---|---|
+| `PackedFile` (named depths) | `PackedItem` (numeric depths) | `numericToDepthLevel()` / `depthLevelToNumeric()` in `reactivePackerWrapper.ts` |
+| `SystemPromptBuilder.build()` | `buildSystemFrame()` string | `buildSystemFrameWithBuilder()` returns both `.text` and `.prompt` |
+| `MemoryStore` (fs-backed) | `memoryPipeline` (Zustand) | Coexist — `memoryStoreIntegration` is additive |
+| `AgentConfig` (search) | `RegistrySkill` / `AgentSummary` | `toSearchableAgent()` mapper |
