Feature Inventory - MultiAgentEval

This document provides a comprehensive inventory of the capabilities, tools, and technical features of the Zero-Touch MultiAgentEval.

1. Zero-Touch Core (Evaluation Engine)

The foundation of the harness, designed for framework-agnostic execution and high-fidelity measurement. - Modular Plugin Bus: Lifecycle hooks (before_evaluation, on_turn_start, after_evaluation) that allow extending the harness without modifying the core. - Dynamic Adapter Discovery: Automatically recognizes and registers agent protocols (http, local, openai, gemini, claude, grok, ollama) via the AgentAdapterRegistry. - Flight Recorder (run.jsonl): Captures every state transition, tool call, and agent response in a deterministic, append-only log. - Virtual File System (VFS): State-aware sandboxing for tool execution with automated rollback and isolation. - Deterministic Trace Signing: Integrated Verifier for SHA-256 signed run traces to ensure data integrity for benchmarks.

2. Security & Compliance (Hardened)

Enterprise-grade protection and regulatory audit tools. - Hardened Sandbox (Docker): (Enterprise) Isolated execution for agent tools using Docker containers to prevent host contamination. - Shell Metacharacter Filtering: Multi-layered defense against command injection in tool parameters. - Credential Stripping: Automated logic to strip sensitive keys (API keys, tokens) from metadata before trace signing. - WORM Audit Logs: Write-Once-Read-Many event streaming for immutable regulatory compliance. - Audit Manifests: Professional JSON manifests generation for every evaluation batch.

3. Semantic Bridge & Drift Management

Closing the loop between production behavior and evaluation rigor. - Import Drift: CLI utility to convert production JSONL traces into actionable evaluation scenarios. - AES (Agent Eval Specification): A portable, YAML-based benchmark format for sharing and versioning complex agentic tasks. - Scenario Linter: Automated quality scoring with Gold/Silver/Bronze badges for AES files. - Adversarial Mutator: Injects typos, ambiguity, and prompt-injection variants into scenarios to test mission-critical robustness.

4. Ecosystem & Framework Adapters

First-class, zero-touch support for the leading AI agent frameworks. - LangChain & LangGraph: Seamless integration for chain-of-thought and graph-based agents. - AutoGen & CrewAI: Direct support for multi-agent orchestrators. - Claude Code & xAI Grok: Optimized adapters for the latest frontier models. - Ollama: Local-first evaluation for private or air-gapped environments.

5. Research & Performance Metrics

Scientific-grade measurement of agent capabilities. - pass@k Scoring: Measures robustness by calculating success probability over multiple stochastic attempts. - Judge Guarding: Strict failure enforcement for required metrics, preventing "soft passes" on safety-critical tasks. - Wilson Score Confidence Intervals: Provides 95% statistical confidence bounds for all reported pass rates. - Grounding Coverage: Heatmaps visualizing tool and knowledge-base utilization within scenarios. - Cost/Latency Analytics: P95 latency monitoring and precise token-based costing mapped to configurable pricing tiers.

6. Visual Suite & Standalone Reporting

Professional-grade dashboards and debugging tools. - Standalone HTML Reports: Single-file, CSS-embedded reports that can be shared via email or Slack without external dependencies. - HuggingFace Mirroring: One-click dataset export (--push-hf) for community benchmark sharing. - Failure Taxonomy: Automated classification of failures into hallucination, timeout, sandbox_breach, etc. - Interactive Trajectory Map: Interactive Mermaid graphs visualizing agent decision paths and environment loops.

7. Developer Experience (multiagent-eval)

Diagnostics and maintenance utilities for the engineer. - Quickstart Demo: 60-second "Instant Gratification" flow including agent spawn and premium report generation. - Interactive Contributor Wizard: Step-by-step CLI (contribute) for building and submitting scenarios to the library. - Harness Doctor: Self-diagnostic tool to verify environment health, dependency versions, and plugin status. - Scenario Scaffold: Markdown-to-AES conversion (spec-to-eval) using local LLMs. - Trace Replay: Step-by-step terminal playback of previous runs for rapid debugging.
