Field note
Agent capabilities are becoming packaged surfaces is a synthesis post, not a separate claim that every linked item has the same weight. The useful signal is the shared direction: Skills, plugins, Hosted MCP, commands, token limits, and bot modes are converging into a packaged capability layer that can be installed, routed, governed, and inspected separately from the base model.
The source evidence for this site row is one accountable public source from the synthesis set, while the remaining links stay attached so a reader or agent can inspect the wider pattern. That keeps the post useful without pretending that a roundup is a single-source release note.
The operational takeaway is simple: the newsroom should track these smaller updates as part of a capability layer. Each individual item may be narrow, but together they change how teams route models, package agent skills, verify output, or govern infrastructure boundaries.
