Agent Studio: Authoring the Roles, Not Just the Knowledge

Skills gave an agent what to know. The missing half is what role to play. Agent Studio lets you author subagents next to your skills in one place, serve both over the same MCP endpoint with the same progressive disclosure, browse them over REST and the dd CLI, and publish them to the community under a moderation loop. Here is the design and why the two belong in one studio.

One Endpoint, Every Capability: A Reference Architecture for Progressive Disclosure

Skills, files, memory, and generation do not need four integrations. They need one MCP endpoint with tiered disclosure, one API key that scopes everything to its owner, and one credit balance. The same tools answer to an MCP client, an in-product chat, and a CLI. Here is the whole architecture, and why it is the shape that makes a fleet of agents coherent.

MCP Servers vs Agent Skills: Which to Build in 2026

A decision framework for 2026: MCP servers give an agent access to a live system, Agent Skills teach it how to do a task. Here is when to build each, when to build both, and the criteria that actually decide it, grounded in the MCP spec and Anthropic's skills docs.

Linked Context: When a Skill Can Point at the Whole Web

The first version of skills-over-MCP served a fixed first-party catalog. Skill Studio extends it two ways: anyone can author skills that ride the same progressive-disclosure endpoint scoped to their own API key, and a skill file can be a link instead of a copy - a URL whose bytes are only fetched at the moment an agent decides it needs them. Progressive disclosure stops at the skill boundary no longer. It runs out to the open web.

The MCP 2026-07-28 Rewrite: What Breaks and How to Migrate

The 2026-07-28 Model Context Protocol spec is the largest revision since launch: a stateless core, deprecated Roots/Sampling/Logging, MCP Apps, Tasks, and tougher OAuth. Here is what breaks, what to adopt, and a migration checklist for server authors and client integrators before the July 28 deadline.

Skills Delivered Over MCP: Why Progressive Disclosure Is the Missing Piece of Both Standards

SKILL.md solved knowledge packaging with progressive disclosure. MCP solved capability transport but ships flat, context-hungry tool lists. The next shape combines them - an MCP server whose tools are a skill directory, so an agent pays context only for what the task needs. Here is the argument and a working implementation.
