[CI Failure Doctor] 🏥 CI Failure Investigation - Run #33728

[github-actions]

Summary

Integration job "CLI Completion & Other" cannot reach proxy.golang.org to download Go modules, so the suite fails before any tests execute.

Failure Details

• Run: 21673794551
• Commit: 56a84c0
• Trigger: push

Root Cause Analysis

go test -v -parallel=8 -timeout=10m -tags integration ./pkg/cli exits during its setup phase because Go is unable to download required modules such as github.com/charmbracelet/huh@v0.8.0, github.com/cli/go-gh/v2@v2.13.0, github.com/fsnotify/fsnotify@v1.9.0, and others; each fetch returns 403 Forbidden from (proxy.golang.org/redacted), so the CLI package is marked [setup failed] and the entire job aborts immediately after reporting FAIL github.com/github/gh-aw/pkg/cli.

Failed Jobs and Errors

• integration matrix entry CLI Completion & Other: go test failed with repeated Get "(proxy.golang.org/redacted) Forbidden errors while resolving dependencies, and the process ended with exit code 1 after printing FAIL for the github.com/github/gh-aw/pkg/cli module.

Investigation Findings

• The HTTP 403s happen before any actual test logic executes, meaning the new runtime cannot compile because dependencies are blocked at the first network request.
• Reproduction: running go test -v -parallel=8 -timeout=10m -tags integration ./pkg/cli locally (inside this workspace) triggers the identical Forbidden errors shown above, which proves the failure is environmental and not caused by broken application logic.
• No cached investigations were found under /tmp/memory/investigations/, so this is the first time we have recorded this pattern for this run.

Recommended Actions

• Verify GitHub runners can successfully download proxy.golang.org/github.com/...; inspect proxy or firewall rules and add the Go proxy to allowed destinations or provide a mirrored module cache.
• Consider vendoring or pre-caching the required modules so that tests do not depend on live proxy downloads that might be blocked in some environments.

Prevention Strategies

• Add an explicit go mod download pre-flight check (with verbose logging) before running integration tests so blocked module fetches fail fast with clear diagnostics.
• Maintain a shared module cache or use GONOSUMDB/GOPRIVATE settings to keep known dependencies available even if the default proxy returns 403 in the future.

AI Team Self-Improvement

Before triggering integration suites, run go mod download and check the HTTP status codes for each module fetch; if any request returns 403/404, surface a targeted error message that calls out the blocked proxy instead of letting go test swallow the issue.

Historical Context

No previous investigations or cached reports describe this exact dependency download failure in /tmp/memory/investigations/, so treat it as a new infrastructure/network regression.
