SYNAPSE Context Engine

Overview

SYNAPSE (Synkra Adaptive Processing & State Engine) is the unified context engine for AIOX. It injects contextual rules into every prompt via an 8-layer processing pipeline, adapting to context window usage through bracket-aware filtering.

What it does:

• Injects rules per-prompt via Claude Code's UserPromptSubmit hook
• Processes 8 layers (L0 Constitution through L7 Star-Commands) sequentially
• Adapts injection volume based on context brackets (FRESH/MODERATE/DEPLETED/CRITICAL)
• Integrates with agent state (active agent, workflow, task, squad)
• Outputs <synapse-rules> XML block appended to each prompt

What it replaces: SYNAPSE replaces the legacy CARL system with full feature parity plus 8 new capabilities including agent-scoped domains, workflow activation, and CRUD management commands.

Architecture model: Open Core — the 8-layer engine lives in aiox-core (open source), memory integration is feature-gated in aiox-pro.

Quick Start

Verify SYNAPSE is Active

SYNAPSE runs automatically via the Claude Code hook. To check status:

*synapse status

This shows: active domains, current bracket, session info, and loaded layers.

Basic Commands

Create a Custom Domain

*synapse create

This walks you through creating a new domain file + manifest entry. See references/domains.md for the full domain guide.

Architecture

SYNAPSE operates as a 4-layer architecture:

.claude/hooks/synapse-engine.js          # Layer 1: Hook Entry (~50 lines)
        |
        v imports
.aiox-core/core/synapse/                 # Layer 2: Engine Modules
|-- engine.js                            #   SynapseEngine class
|-- layers/                              #   8 layer processors (L0-L7)
|-- session/session-manager.js           #   Session state (JSON v2.0)
|-- domain/domain-loader.js              #   Manifest + domain parser
|-- context/context-tracker.js           #   Bracket calculation
|-- memory/memory-bridge.js              #   Pro-gated MIS consumer
|-- output/formatter.js                  #   <synapse-rules> XML
        |
        v reads/writes
.synapse/                                # Layer 3: Runtime Data
|-- manifest                             #   Central domain registry (KEY=VALUE)
|-- constitution, global, context        #   Core domains (L0, L1)
|-- agent-*, workflow-*                  #   Scoped domains (L2, L3)
|-- commands                             #   Star-command definitions (L7)
|-- sessions/, cache/                    #   Session state (gitignored)
        |
        v user-invoked
.claude/commands/synapse/                # Layer 4: CRUD Commands + Skill Docs
|-- manager.md                           #   Router/dispatcher
|-- tasks/ (6 tasks)                     #   create, add, edit, toggle, command, suggest

Key principle: SYNAPSE is a consumer of existing systems (UAP for session state, MIS for memories). It never rewrites code from other epics.
