Superpowers Bridge

Superpowers Bridge packages the superb Spec Kit extension. It applies five selected obra/superpowers disciplines at bounded lifecycle points without importing the complete Superpowers workflow.

Boundary

Spec Kit owns specify -> clarify -> plan -> tasks -> implement -> converge. Superb contributes optional specification refinement, mandatory test-first readiness, and four standalone developer disciplines. It owns no plan, task store, execution lifecycle, completion state, or convergence command.

Commands

Command	Purpose
/speckit.superb.check	Diagnose the focused capability contract.
/speckit.superb.brainstorm	Refine the active spec after user approval.
/speckit.superb.implementation-gate	Report test-first readiness before implementation.
/speckit.superb.critique	Review implementation evidence without applying fixes.
/speckit.superb.debug	Investigate the current failing task.
/speckit.superb.respond	Verify and respond to supplied review feedback.
/speckit.superb.finish	Perform an explicit post-convergence branch handoff.

Hook Registration

Hook	Command	Policy
after_specify	/speckit.superb.brainstorm	Optional
before_implement	/speckit.superb.implementation-gate	Required

Skill Contract

Superb directly uses five Superpowers skills:

• brainstorming
• test-driven-development
• systematic-debugging
• receiving-code-review
• finishing-a-development-branch

All five are optional upstream enhancements to the Spec Kit path. Test-first behavior remains required through the bridge-native minimum when test-driven-development is unavailable; missing standalone-command skills disable only their corresponding Superb command.

The complete plugin may be installed for distribution convenience, but other bundled skills are not Superb runtime dependencies.

Installation

specify extension catalog add https://raw.githubusercontent.com/RbBtSn0w/spec-kit-extensions/main/catalog.json \
  --name rbbtsn0w-spec-kit-extensions --priority 1 --install-allowed
specify extension add superb
specify extension update superb

Published release installation:

specify extension add superpowers-bridge --from https://github.com/RbBtSn0w/spec-kit-extensions/releases/download/superpowers-bridge-v1.9.0/superpowers-bridge.zip

Local development installation:

specify extension add --dev ./superpowers-bridge

Superpowers installation choices are offered only after explicit user approval:

npx @rbbtsn0w/adg plugins add obra/superpowers -g
npx @rbbtsn0w/adg skills add obra/superpowers --skill brainstorming --skill test-driven-development --skill systematic-debugging --skill receiving-code-review --skill finishing-a-development-branch --global -y

Migration

Existing users must remove references to the old controller, post-tasks review, completion command, status synchronization, and evidence archives. See WORKFLOW.md for owning Spec Kit routes.
