Spec Kit Extensions

Evidence-first extensions for Spec Kit workflows.

The current wedge is focused lifecycle reinforcement: selected disciplines add specification quality, test-first readiness, debugging, review, and branch handoff without creating a second Spec Kit workflow.

Extensions

Compatibility: These extensions target Spec Kit >=0.12.0. As of 0.12, the upstream agent-context extension is a full opt-in — specify init no longer installs it, and nothing in Spec Kit touches the agent context file unless you enable it. MemoryLint works with or without agent-context: when it is enabled, MemoryLint skips the <!-- SPECKIT START/END --> managed block it maintains in AGENTS.md/CLAUDE.md.

Installation

Register this repository's catalog once so Spec Kit can install and update extensions from an install-approved source:

specify extension catalog add https://raw.githubusercontent.com/RbBtSn0w/spec-kit-extensions/main/catalog.json \
  --name rbbtsn0w-spec-kit-extensions \
  --priority 1 \
  --install-allowed \
  --description "RbBtSn0w Spec Kit Extensions"

Then install or update by the extension IDs declared in the catalog:

specify extension add superb
specify extension update superb

specify extension add memorylint
specify extension update memorylint

For one-off installs without catalog-managed updates, install a single extension from a published release:

specify extension add superpowers-bridge --from https://github.com/RbBtSn0w/spec-kit-extensions/releases/download/superpowers-bridge-v1.9.0/superpowers-bridge.zip
specify extension add memorylint --from https://github.com/RbBtSn0w/spec-kit-extensions/releases/download/memorylint-v1.8.0/memorylint.zip

For local development, clone this repository and either install a specific extension or register every top-level extension discovered by install.sh:

git clone https://github.com/RbBtSn0w/spec-kit-extensions.git
cd spec-kit-extensions

specify extension add --dev ./superpowers-bridge
# or
./install.sh

Product Direction

• Now: focused specification refinement, test-first readiness, debugging, review, and branch handoff for Spec Kit users.
• Next: MemoryLint semantic audits for long-lived agent instructions.
• Later: Universal Bridge portability once the Spec Kit loop proves useful in real repositories.

Development

1. Clone this repository.
2. Add your extension in a new directory.
3. Register your development extension locally:

specify extension add --dev ./[extension-name]
