Spec Kit — extensions

Manage spec-kit extensions with the Specify CLI specify extension command group. Extensions add reusable commands/hooks to a spec-kit project.

Prerequisite: needs the specify CLI. If specify --version fails, install it with the speckit-cli-setup skill first.

When to use

Find, install, update, or remove a spec-kit extension.
Temporarily enable/disable an extension or adjust its resolution priority.
Add or manage extension catalog sources.

How to invoke

# Discover
specify extension list
specify extension list --json                 # machine-readable installed inventory (CLI >= 1.0.7)
specify extension search <query>
specify extension info <name>

# Install
specify extension add <name>
specify extension add <name> --force            # overwrite if already installed
specify extension add <path> --dev              # install from a local directory
specify extension add <name> --from <url>       # install from a custom URL
specify extension add <name> --priority <n>     # lower number = higher precedence

# Lifecycle
specify extension update [<name>]               # update one or all extensions
specify extension enable <name>
specify extension disable <name>
specify extension set-priority <name> <n>
specify extension remove <name>

# Catalogs (sources extensions are resolved from)
specify extension catalog list
specify extension catalog add <https-url> --name <name> [--install-allowed] [--priority <n>] [--description <text>]
specify extension catalog remove <name>

Extension catalog URLs must use HTTPS. New catalogs are not install-allowed by default — pass --install-allowed to permit installing extensions from them.

Notes

Resolution priority: lower number = higher precedence (default 10).
specify extension list --json requires Specify CLI >= 1.0.7 and returns installed extensions only, even when combined with --available or --all. Each item includes id, name, description, version, nullable author, priority, enabled, normalized source, and provides counts for commands, templates, scripts, and hooks.
Prefer specify extension search first so you install the correct extension ID.
--dev is for local development of an extension; point it at the extension's source directory.
When the project was initialized in skills mode (see the speckit-init skill), an installed extension's commands land as .github/skills/speckit-<cmd>/SKILL.md. To make Copilot pick up the new skills in the current session, run /skills reload (no restart needed). They are also loaded automatically on the next session start.

概要と使いどころ

speckit-artifact

無料

Inspect the effective Spec Kit artifact inventory and composition stacks via `specify artifact`. USE FOR: listing commands/templates/scripts/hooks, explaining which preset or extension layer supplies an artifact, inspecting resolution precedence and hidden layers, checking hook registration, or resolving a stack lookupId to its validated contribution. DO NOT USE FOR: installing or changing presets/extensions (use speckit-preset or speckit-extension), resolving only a preset-managed filename (use speckit-preset), or running an artifact.
