Focused guidance, explicit scope

The b10x marketplace publishes a front door and four specialist plugins. Install the front door when you want routing, ecosystem resources, or portable plugin creation. Install a specialist directly when the work is already clear.

Every plugin starts with /<plugin>:init and checks itself with /<plugin>:upgrade; /b10x:init asks what you want to do and installs the matching plugins and CLIs.

The marketplace contains instructions, not credentials. A plugin does not acquire authority to write a repository, contact a service, or bypass an approval boundary merely because it is installed.

New to ESS? Your first ESS specification takes you from an empty directory to a validated specification and a passing conformance suite, with an agent doing the writing, and Your first governed plan continues it with an AEP plan and one reviewed wave. Otherwise set up with one sentence, start with the front door or choose a specialist.
