HTTP GET %s: %w

Error message

HTTP GET %s: %w

What it means

fetchSkillPresetsFromURL wraps errors from the Go http.Client.Get call with "HTTP GET %s: %w". This is a transport-level failure: the request never completed, so no HTTP status exists. The URL is included so you can tell which preset source failed.

Solutions

1. curl the URL from the same host to reproduce: curl -v <url>
2. Fix DNS/proxy issues (HTTPS_PROXY env, /etc/hosts, VPN) or correct the URL in config
3. Retry — transient network blips and timeouts are common; the fetch caller aggregates multiple sources
4. If the URL is consistently unreachable, remove or replace that source

Example fix

// before
url = "http://presets.internal.example/skills.json"
// after
url = "https://presets.example.com/skills.json"  # verify with curl first

u, err := url.Parse(sourceURL)
if err != nil { return fmt.Errorf("invalid presets URL: %w", err) }
if u.Scheme != "http" && u.Scheme != "https" { return fmt.Errorf("unsupported scheme %q", u.Scheme) }
// optional connectivity pre-check
conn, err := net.DialTimeout("tcp", net.JoinHostPort(u.Hostname(), portOrDefault(u)), 3*time.Second)
if err != nil { return fmt.Errorf("preset host unreachable: %w", err) }
conn.Close()

var presets *SkillPresetsResponse
var lastErr error
for attempt := 0; attempt < 3; attempt++ {
    presets, lastErr = fetchSkillPresetsFromURL(url, timeout)
    if lastErr == nil { break }
    if strings.HasPrefix(lastErr.Error(), "HTTP GET") { time.Sleep(time.Duration(attempt+1) * 2 * time.Second) }
}
if lastErr != nil { slog.Error("presets fetch failed after retries", "url", url, "err", lastErr) }

When it happens

Trigger: DNS resolution failure, connection refused, TLS handshake error, or request timeout (the client uses a per-fetch timeout) while GETting a skill presets source URL from fetch.

Common situations: Offline laptop / air-gapped server; typo'd scheme or host in the presets URL; corporate proxy requiring configuration; long timeout hit on a slow mirror.
