Build MCP Skill

Installs the WordPress MCP adapter (pre-compiled, bundled at vendor/mcp-adapter/) into the build's wp-content/plugins/ directory, activates it via WP-CLI so activation is captured in the SQL export, writes a README.md with STDIO transport configuration, and updates build.json with MCP adapter metadata.

Critical sequencing: This skill runs AFTER build-scaffold Section 4 (WP-CLI pipeline including first wp db export) and BEFORE zip packaging. The Docker MySQL container from build-scaffold must still be running when this skill executes — the EXIT trap set in build-scaffold Section 3 must remain active for the duration of this skill.

This skill expects the following variables to already be set by the calling command:

• BUILD_DIR — absolute path to the build directory (set by build-scaffold Section 2)
• WP — the WP-CLI command prefix (e.g., wp --path=$BUILD_DIR or the Docker equivalent, set by build-scaffold Section 4)
• PLUGIN_DIR — absolute path to the CoWork plugin directory (set by COMMAND.md before invoking this skill)

Section 1: MCP Adapter Copy

Copy the pre-compiled MCP adapter from the CoWork plugin's vendor/mcp-adapter/ directory into the build's WordPress plugins directory.
