Pack Guard

Runtime check that verifies required skill packs are enabled before a command runs.

When invoked

Any command whose frontmatter declares requires: with one or more optional packs.

Protocol

1. Read .dog/config.json from the dog_stack plugin root

   • If file does not exist: assume all packs are enabled (backwards compatible with pre-onboarding installs)
   • If file exists but malformed: warn and assume all packs are enabled

2. For each pack listed in the command's requires: field:

   • Check packs[packName].enabled === true
   • If disabled: STOP immediately and output this message:

This command requires the '<pack-name>' pack, which is not enabled.

Enable it now:
  /dog:onboard --enable <pack-name>

Or reconfigure all packs:
  /dog:onboard

Currently enabled packs: <list>

1. If all required packs are enabled: proceed with the command normally (no output from pack-guard)

Behavior

• Never blocks core commands — core pack is always locked enabled
• Backwards compatible — missing config.json → all packs considered enabled
• Actionable errors — every block message includes the exact command to fix it
• Fast — single file read, no network, no subprocess
