← All postsOne org, many agents: Claude Code, Codex and a bot on one rulebook
How a team keeps each member's own client, shares app connections, runs one approval policy and one ledger, and gives bots an identity of their own.

What does human-in-the-loop mean for AI agents in 2026?
Human-in-the-loop means a person decides named actions before they run, under a policy written in advance. Reads never wait, and an approved call runs once.
What is agent memory? Shared, private, and owned by the org
Agent memory is durable, searchable state that outlives one conversation, client or agent. How it differs from a context window, and who owns it.
What is an agent identity (and why not just an API key)?
An agent identity is a principal of its own, with an id, keys, an owner who answers for it, and reach limited to shared connections. A personal API key acts as you.
What is Harness-as-a-Service (HaaS)?
Harness-as-a-Service is a hosted harness any agent signs into. Tools, auth, memory, budgets and an audit trail come as one service, and the agent you run stays yours.
What is MCP, explained for teams running several agents
MCP is the JSON-RPC protocol an agent uses to list and call tools on a server. For teams, one remote server means shared connections, one policy and one ledger.
