Emergent Tool Composition
The runtime-generated sequencing and combination of tool calls an agent assembles fresh for a given task from whatever capabilities are available, replacing human-authored/reviewable integration logic with a decision that doesn't exist as a testable artifact until the moment it's made.
Also known as: composition (emergent), unplanned tool composition, runtime composition, composition risk, agent-composed integration

MCP is not a plumbing/API-standard convenience but a structural shift in who composes integration logic — from developers pre-agreeing a contract to an agent assembling one at runtime out of natural-language tool descriptions — which makes tool descriptions the real interface, unplanned tool composition a structural risk no test suite catches, and enforced governance a precondition for production use rather than later hardening. - The Future of Work by Henrik Kniberg Jfokus · 2025-02-09 source ↗ Reader 🖥️
AI agents are rapidly maturing from autocomplete tools into autonomous colleagues capable of researching, coding, communicating, and even improving their own platform via human-reviewed pull requests — shifting the developer's job from writing code to directing, evaluating, and choosing where to spend increasingly scarce attention.
