Agent Skills and the Model Context Protocol (MCP) are complementary, not redundant. Skills package internal, repeatable workflows for 'doing the thing,' while MCP provides the open standard for connecting to external systems like databases and APIs for 'reaching the thing.'

OpenAI integrated the Model-Centric Protocol (MCP) into its agentic APIs instead of building its own. The decision was driven by Anthropic treating MCP as a truly open standard, complete with a cross-company steering committee, which fostered trust and made adoption easy and pragmatic.

Bluesky wasn't founded to be a Twitter clone, but to deconstruct social media into modular components (identity, social graph). This protocol-based approach aims to solve the "cold start" problem for new apps, fostering an ecosystem of competition and user choice beyond a few dominant platforms.

Instead of traditional ads, Bluesky aims to generate revenue by enabling commerce across the entire AT Protocol ecosystem. They plan to take a small percentage of transactions they help facilitate, such as subscriptions, creating a model where they only succeed if the whole network thrives.

Current identity standards like OIDC are insufficient for AI agents. The future requires a "three-legged stool" identity combining a service account (the agent's identity), owner role claims, and "on-behalf-of" claims inherited from the user.

To ensure the AT Protocol remains open, Bluesky is handing over critical components to independent bodies. The core identity directory is moving to a Swiss nonprofit, and the protocol specification is being submitted to the IETF. This preemptively removes Bluesky as a single point of control or failure.

The next major evolution for the public-by-default AT Protocol is adding support for private data, enabling private groups. CEO Tony Schneider sees this as the number one request from developers and the key to unlocking "10 or a 100 X the number of use cases," moving beyond the public square model.

The blockchain ecosystem is not a single network but many fragmented 'zones' with different rules, much like the early internet. Cross-chain interoperability protocols serve the same function as TCP/IP, providing a standardized messaging layer to connect these disparate public and private chains, creating a cohesive network from fragmented parts.

CEO Tony Schneider frames the popular Bluesky app not as the core product, but as an "on-ramp or maybe a lobby" for the underlying AT Protocol. Its primary strategic function is to attract a critical mass of users to solve the cold-start problem for third-party developers, making the entire ecosystem viable.
