olore-a2a-latest is a skill for Claude Code, Codex from olorehq/olore. It costs 41 tokens per session (660 once invoked), scanned A, original, MIT.

A local reference package for A2A, an open standard that lets AI agents built with different systems communicate and cooperate.

In plain words
What is it for?
Use it to understand or implement A2A agents, task lifecycles, agent cards, asynchronous updates, push notifications, and the Python SDK.
Why use it?
It provides organized guidance on agent communication, task handling, streaming, notifications, and interoperability.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

olore-a2a-latest scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

A2A Protocol Documentation

The Agent2Agent (A2A) Protocol is an open standard for seamless communication and collaboration between AI agents. It provides a common language for agents built with diverse frameworks (LangGraph, CrewAI, Semantic Kernel, ADK, etc.) enabling interoperability across organizational and platform boundaries. Originally developed by Google and donated to the Linux Foundation.

When to use

Use this skill when the user asks about:

  • Implementing A2A protocol in an agent (client or server side)
  • Agent-to-agent communication and interoperability
  • Task management: creating, streaming, and completing tasks
  • Agent Card format and agent discovery
  • Streaming responses and asynchronous/push-notification patterns
  • Enterprise deployment: authentication, security, multi-tenancy
  • Protocol extensions and custom transport bindings
  • How A2A relates to or works alongside MCP
  • Python SDK usage or the step-by-step Python tutorial

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
