agent-protocols

Contract lab for agent protocol envelopes - versioned MCP/A2A message contracts, envelope validation, and compatibility diffs (compatible/forward/breaking). Python 3 stdlib + optional .NET 9 runtime.

A curated list of protocols and standards for AI agents — MCP, A2A, ACP, AG-UI, AP2, x402, and 50+ more, organized by stack layer

A curated directory of AI agent infrastructure projects: runtimes, sandboxes, memory, identity, observability, workflows, and protocols.

⚡️ Answer the accountability question about your organization in ninety seconds: seven questions, three files at well-known paths, and a URL you can paste into a vendor questionnaire. Not released yet.

A protocol specification and lightweight frontend runtime for AI agent-driven interfaces. Three commands, one JSON stream, zero backend dependencies.

Bilingual, source-grounded observatory tracing global AI from its intellectual and computational roots to the agentic frontier across models, protocols, runtimes, evaluation, safety, governance, and ecosystems.

meshcognition.org — the cognitive substrate beneath the agentic mesh. Mesh intelligence on an open protocol: the Mesh Memory Protocol (MMP). Pioneered by SYM.BOT.

Awesome Agent SDLC v1.2 — Open-source standard documentation repository for AI-agent-assisted software development: agent roles, the A2A handoff protocol, the JUDGE verification layer, a maturity model, and multi-AI-tool (Cursor, Gemini, Claude, Copilot) configurations. Licensed AGPL-3.0.

A minimal contract for two AI coding agents working the same repo — git as the message bus, human owner at the gates

A curated, layer-by-layer guide to protocols and standards for integrating LLM agents, with practical trade-off comparisons.

Awesome list of open-source AI agent identity, trust, governance, security, and naming projects. Protocols, standards, tools for agent verification, permissions, attestation, reputation, and policy enforcement.

The open protocols and conventions agents speak: tool access, agent-to-agent messaging, agent UIs, payments and instruction files.

Bilingual, source-grounded observatory of China's AI and agent ecosystem across history, policy, standards, research, open source, infrastructure, industry, applications, evaluation, safety, and governance.

Agents, Orchestrated. Real builds on the agentic stack, one layer per episode. Autonomy is table stakes; the moat is everything around the agent.

Two companion A2A extension specifications: the Agent Transparency Profile (signed per-answer disclosures) and the Agent Dialog Profile (binding verification dialog between agents)

⛏️ evidence-traced agent protocols for rediscovering overlooked research — autopsies for sleeping-beauty papers, any harness

EP 03 of Agents, Orchestrated. A shopping agent with an ES256-signed $7,000 spending mandate, and the three times it gets refused. AP2 + Camunda 8, fully runnable.

Workflow docs, Birdseye/Codemap, Task Seeds, acceptance operations, reusable CI, context engineering, and plugin-based evidence tracking

4-tier agentic supply-chain testbed (beer game) for benchmarking agents.
