v1.8.1 — Core Abstractions & Handler Integration

v1.8.1 — Core Abstractions & Handler Integration

Core Abstractions (Convergence Plan v2.0)

• Signal Protocol: Unified message type for inter-agent communication
  • Signal class with confidence scoring and source attribution
  • SignalBus for event-driven signal routing
  • ConsensusCalculator for multi-model consensus
• Parameter Normalization: Single declarative alias system
  • Global aliases (q→query, k→limit, cost→costPreference)
  • Replaces 10+ scattered normalizer functions
• Schema Registry: Centralized Zod schemas with composable building blocks
  • Domain-organized schemas (Research, KB, Job, Graph, Session, Util, Web)
• RoleShift Protocol: Bidirectional communication via MCP sampling/elicitation

Handler Integration (Phase F)

• Feature-flagged routing: CORE_HANDLERS_ENABLED=true routes 28 tools through handlers/
• wrapWithHandler(): Unified wrapper function for handler → legacy fallback
• Zero behavioral change: When handlers disabled, all tools use legacy implementations
• Tools integrated: ping, date_time, calc, list_tools, search_tools, job_status, cancel_job, task_, undo, redo, fork_session, time_travel, session_state, checkpoint, graph_, search, query, retrieve, get_report, history

Consolidated Handlers

• New src/server/handlers/ directory with domain-organized handlers
• Master router in handlers/index.js for 28 tools

Error Visibility & Reliability

• Error Infrastructure: MCPError, APIError, ConfigurationError classes
• Pre-flight Checks: API key, database, and embedder validation
• Job Worker Improvements: Fixed silent error swallowing, enhanced failure details

Codebase Cleanup

• Removed 5 Windows .bat files, old archives, and 6 stale docs
• Fixed duplicate searchTool() in tools.js

Installation

```bash
npm install @terminals-tech/openrouter-agents@1.8.1
```

Usage

```bash

Enable new handler routing

CORE_HANDLERS_ENABLED=true npx @terminals-tech/openrouter-agents --stdio

Legacy mode (default)

npx @terminals-tech/openrouter-agents --stdio
```
