Full-stack-skills speckit-install

Install the Specify CLI on the host machine (uv tool install or uvx one-time); supports multiple OS, persistent or one-time install, and corporate or restricted-network environments. Use when the user says "install Spec Kit", "install Specify CLI", or "specify command not found".

Spec Kit Install Skill

Install the Specify CLI so that

specify
is available in PATH (or use one-time
uvx
). This skill covers only installing the CLI; it does not run
specify init
. For project initialization after install, use speckit-initial.

When to Use

  • First-time Spec Kit setup ("install Spec Kit", "install Specify CLI").
  • CI or scripts that need to pre-install the CLI.
  • Upgrading the CLI (
    uv tool install --force
    ).
  • User reports "specify command not found" or "specify: command not found".

Prerequisites

  • uv: Astral uv for installing the CLI. If uv is not installed, guide the user to install it first (e.g.
    curl -LsSf https://astral.sh/uv/install.sh | sh
    on Linux/macOS, or see uv docs for Windows).
  • Python 3.11+ when using uv (uv typically bundles or uses system Python).
  • Git (optional for install; required later for
    specify init
    with git).

Workflow

  1. Check if already installed

    • Suggest running
      specify --version
      or
      specify check
      . If the command succeeds, the CLI is already installed; suggest speckit-initial for project init or speckit-check for environment verification.
  2. Persistent install (recommended)

    • Run:
      uv tool install specify-cli --from git+https://github.com/github/spec-kit.git
    • This makes
      specify
      available in PATH for all projects.
    • Upgrade:
      uv tool install specify-cli --force --from git+https://github.com/github/spec-kit.git
  3. One-time usage (no PATH install)

    • Run:
      uvx --from git+https://github.com/github/spec-kit.git specify init <project_name_or_.> --ai <agent>
    • Use when the user does not want to install the tool permanently (e.g. quick try, CI one-off). Document that subsequent
      specify init
      or
      specify check
      in the same session can reuse the same
      uvx
      prefix or require re-running with full
      uvx --from ...
      if not installed.
  4. Corporate or restricted network

    • Set
      GH_TOKEN
      or
      GITHUB_TOKEN
      for GitHub API access if needed.
    • For
      specify init
      (handled in speckit-initial):
      --github-token <token>
      or env var. For install, uv may need network access to clone the repo; if TLS issues occur, document that uv/spec-kit may support
      --skip-tls
      or similar only where explicitly documented (avoid recommending insecure options unless user is in a controlled environment).

Outputs

  • Persistent install:
    specify
    is available in PATH; user can run
    specify init
    ,
    specify check
    in any directory.
  • One-time: No change to PATH; user runs
    uvx --from git+https://github.com/github/spec-kit.git specify ...
    for each use.

Next Steps

  • After install: use speckit-initial to run
    specify init
    in a project, or speckit-check to verify the environment.

Different Environments

EnvironmentNotes
LinuxInstall uv if needed; then
uv tool install specify-cli --from git+https://github.com/github/spec-kit.git
. WSL: same as Linux.
macOSSame as Linux; ensure Python 3.11+ available for uv if required.
WindowsInstall uv (see uv docs); use PowerShell or cmd. For project init, speckit-initial will use
--script ps
when needed.
Corporate / proxyUse GH_TOKEN/GITHUB_TOKEN if GitHub API is restricted; ensure uv can reach GitHub.
CIPrefer persistent install in a cacheable step:
uv tool install specify-cli --from git+https://github.com/github/spec-kit.git
; then run
specify init
or
specify check
in the same runner.

Troubleshooting

  • uv not found: Direct user to install uv.
  • Python version: uv usually manages Python; if errors mention Python, ensure 3.11+ is available.
  • Network / SSL: Check firewall, proxy, and GitHub access; avoid disabling TLS unless necessary and documented.
  • Permission errors: On Linux/macOS, user install with uv typically does not need sudo; if using system Python, consider user-level uv install.
