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.
