+# Agent Plugins and Yield
+
+Agent Plugins and Yield solve different parts of the same delivery path:
+
+- **Agent Plugins packages a capability.** Its manifest and fixed directories let
+  compatible clients discover Agent Skills and MCP servers.
+- **Yield governs execution.** A Yield program owns repeatable order, branches,
+  checks, human decisions, saved state, and terminal outcomes.
+
+In short: **Agent Plugins packages the capability. Yield governs the execution.**
+
+## Current support boundary
+
+Yield does not currently emit an Agent Plugins `plugin.json`, install plugins, or
+load MCP servers. `yskill register` writes a small `SKILL.md` adapter into a coding
+agent's project skill directory and keeps the canonical workflow beside the
+project dependencies it uses.
+
+That adapter alone is not proof that a package conforms to Agent Plugins. A
+conformant plugin must satisfy the complete Agent Plugins manifest, containment,
+component-discovery, and Agent Skills requirements. Yield does not claim Agent
+Plugins v1 conformance in this release.
+
+## Using the projects together
+
+You can package skills however you like and use Yield for the repeatable workflow
+behind them. Keep these boundaries explicit:
+
+1. the plugin package owns discovery and portable package structure;
+2. the Yield program owns workflow execution and verification;
+3. the host owns installation, permissions, and the agent interaction surface.
+
+A future plugin export should be treated as a separate, tested distribution
+feature. It should not change Yield's execution contract.
+
+See the [Agent Plugins specification](https://agent-plugins.org/specification) and
+the [Agent Skills specification](https://agentskills.io/specification) for their
+normative requirements.
