This looks like a corporate environment issue

Can you try:

# Prefer your organization’s approved PyPI mirror
$env:UV_DEFAULT_INDEX = "https://<approved-mirror>/simple"

# If IT provides a corporate CA bundle
$env:SSL_CERT_FILE = "C:\path\to\corporate-ca.pem"

# If an explicit proxy is required
$env:HTTPS_PROXY = "http://<proxy-host>:<port>"

uv --system-certs tool install --force --python 3.14 specify-cli `
  --from "git+https://github.com/github/spec-kit.git@v1.0.0"

You were right. I needed to create %APPDATA%\uv\uv.toml with the org specific index.

This bug can be closed.
