Rubric Protocol Adds Post‑Quantum Audit Trails for Python Agents
Rubric Protocol, built by a solo founder, released autogen-rubric — a Python library that instruments AI agents to produce cryptographically signed, tamper-proof compliance logs intended to meet regulatory audit needs (e.g., EU AI Act Article 12). The package signs every agent action with a NIST-standardized post-quantum signature (ML-DSA-65 / CRYSTALS‑Dilithium), batches actions into Merkle trees, anchors root hashes to the Hedera Consensus Service mainnet, and issues W3C Verifiable Credentials. Installation is a one-line call (pip install autogen-rubric) and runtime instrumentation is rubric.instrument(). The implementation uses a C++ N-API addon for native ML-DSA-65 signing (claimed 52x faster than JS equivalents). Rubric reports load testing at 3,247 RPS with a 0.13% error rate and says the first mainnet verifiable credential was issued on 2026-04-03.
Provides a turnkey, post-quantum, tamper-proof compliance logging solution for AI agents—useful for teams subject to regulations like the EU AI Act—but is a startup-level technical release rather than a major platform change.

Key Takeaways & Evidence Grounding
- Rubric Protocol released the autogen-rubric Python package to add cryptographic audit trails for AI agents.
- Instrumentation is one line: import rubric; rubric.instrument(), and the package supports frameworks like LangChain, AutoGen, LlamaIndex, Haystack, Semantic Kernel, and others.
- Every agent action is signed with ML-DSA-65 (CRYSTALS‑Dilithium), batched into a Merkle tree, anchored to Hedera Consensus Service mainnet, and exportable as a W3C Verifiable Credential.
- Post-quantum signing implemented via a C++ N-API addon, claimed to be 52x faster than pure JavaScript equivalents.
- Rubric reports load testing at 3,247 RPS with a 0.13% error rate; first mainnet verifiable credential issued on 2026-04-03.

AgentRisk Launches Trust Badges for AI Agents
AgentRisk, a trust-scoring platform for AI agents, has launched an embeddable Trust Badge that displays an agent's trust score and tracking days. The badge links to a full scorecard based on a public, six-dimension framework (Authenticity, Consistency, Transparency, Commitment, Choice, Presence) and uses public data sources (e.g., HuggingFace profiles, GitHub repos, on-chain events). Scores are cryptographically verifiable via Ed25519 signatures anchored to a hash chain. AgentRisk indexes 964,488 agents across 28 platforms and supports claiming via GitHub file verification or platform description verification. The initial badge is a 240×80 widget (dark theme) with copy-paste Markdown embed code; the company positions the badge as an early-stage shared signal for developers to indicate tracked and verified agents.
Cert‑gating Tool Calls for Zero‑Trust AI Agents
A developer describes an open‑source agent security kernel that enforces zero‑trust for AI agents by cert‑gating every tool invocation. The kernel requires all tool calls to pass through an enforce_policy function which validates strict JSON schemas, attaches provenance-tagged values (pv/Prov), enforces taint-flow invariants (TAINTED never becomes TRUSTED), and checks scoped, time‑limited, budgeted capability tokens. Successful checks mint signed artifacts (e.g., TOOL_CALL_CERT.v1, TAINT_FLOW_CERT.v1) and all events are recorded in an append‑only Merkle trace; failures emit structured obstruction artifacts (PROMPT_INJECTION_OBSTRUCTION.v1). The project is MIT licensed, available at github.com/1r0nw1ll/agent-security-kernel, and published as a pip package. The design targets multi‑model orchestration use cases (Claude, GPT/Codex, open‑source models) and aims to close provenance-based prompt‑injection gaps.
Signed, Reusable Attestations for AI Agent Verification
A developer published a technical post describing a pattern to avoid redundant verification by AI agents: treat verification results as signed, portable, reusable attestations instead of repeated checks. The author describes an implementation (Erabi) that probes paid agent services periodically, publishes JSON attestations signed with Ed25519 over an RFC 8785-canonicalized payload, and exposes endpoints for agents to fetch and verify attestations. The index currently covers 16 pay-per-call services and is open-source (Apache-2.0) on GitHub. The approach aims to reduce wasted calls, latency, and cost by letting agents verify a single signature rather than re-deriving trust each time.
