Agentic AI

AI agents from pilot to production: MCP tool design, delegated access, reliability, evaluation and coding agents, from published evidence.

How reliably the best AI agents succeed when it counts, in plain language: success on every try, the length of task they can handle, and realistic office work. From the official leaderboards, updated when they change.

Delegated access for agents: OAuth 2.1, PKCE and scoped tokens

On whose behalf is the agent acting, and with what rights? The delegation model I use, what the MCP authorization specification requires as of 2026, how to design scopes, and where agent credentials actually leak.
