Pull request overview

Fixes a CI failure in the agent container startup by preventing Claude Code config files from being clobbered when adding apiKeyHelper, preserving existing Claude Code state.

Changes:

Update write_api_key_helper to merge apiKeyHelper into existing JSON using node, rather than overwriting the entire file.
Add a fallback path that overwrites the config if the Node-based merge cannot run.

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

+             obj.apiKeyHelper = helper;
+             fs.writeFileSync(file, JSON.stringify(obj) + '\n');
+           " 2>/dev/null; then

+        fi


The node -e merge currently treats invalid JSON as success because JSON.parse(...) errors are swallowed. That means the else branch (commented as "file is not valid JSON") will never run for parse failures, and the log will say "Merged" even though the file was effectively overwritten with only apiKeyHelper. Consider making parse failures cause a non-zero exit (so the fallback path is taken and/or a clearer log is emitted), or update the comment/logging to reflect the actual behavior.

containers/agent/entrypoint.sh

+          # Fallback if node is unavailable or the file is not valid JSON
+          echo "{\"apiKeyHelper\":\"$CLAUDE_CODE_API_KEY_HELPER\"}" > "$config_file"
+          chmod 666 "$config_file"
+          echo "[entrypoint] ✓ Wrote apiKeyHelper to $label (overwrite fallback)"


The fallback JSON write uses echo "{\"apiKeyHelper\":\"$CLAUDE_CODE_API_KEY_HELPER\"}", which will produce invalid JSON (or change semantics) if CLAUDE_CODE_API_KEY_HELPER contains characters like quotes, backslashes, or newlines. Since this branch is used when node is missing/fails, it would be safer to generate JSON via a proper encoder (e.g., Node/JSON.stringify or another escaping approach) rather than interpolating directly into a JSON string.

See below for a potential fix:

AWF_KEY_HELPER="$CLAUDE_CODE_API_KEY_HELPER" python - << 'EOF' > "$config_file" import json, os, sys helper = os.environ.get("AWF_KEY_HELPER", "") json.dump({"apiKeyHelper": helper}, sys.stdout) sys.stdout.write("\n") EOF chmod 666 "$config_file" echo "[entrypoint] ✓ Wrote apiKeyHelper to $label (overwrite fallback)" fi fi else echo "[entrypoint] Creating $label with apiKeyHelper..." AWF_KEY_HELPER="$CLAUDE_CODE_API_KEY_HELPER" python - << 'EOF' > "$config_file" import json, os, sys helper = os.environ.get("AWF_KEY_HELPER", "") json.dump({"apiKeyHelper": helper}, sys.stdout) sys.stdout.write("\n") EOF

This change is fixing a CI blocker by preserving existing Claude Code config fields while adding apiKeyHelper, but there doesn’t appear to be an automated test that exercises the write_api_key_helper behavior (e.g., pre-seeded ~/.claude.json and ~/.claude/settings.json with additional fields, then verifying they are preserved and apiKeyHelper is set). Adding an integration test for this merge path would help prevent regressions in future entrypoint edits.

….1.81+ (#1414) * fix: write apiKeyHelper to ~/.claude/settings.json for Claude Code v2.1.81+ Claude Code v2.1.81+ reads apiKeyHelper from ~/.claude/settings.json instead of ~/.claude.json. The entrypoint now writes to both paths for backward/forward compatibility.

Combined with the missing EXCLUDED_ENV_VARS entry for the --env-all code path, GITHUB_API_URL was leaking into the agent container when api-proxy is enabled. With GITHUB_API_URL present in the agent, the Copilot CLI routes its token exchange to api.github.com/copilot_internal/v2/token using the placeholder COPILOT_GITHUB_TOKEN instead of going through COPILOT_API_URL → api-proxy (which injects the real token), causing a 401 authentication failure. Fix: - Add GITHUB_API_URL to EXCLUDED_ENV_VARS when api-proxy is enabled (covers the --env-all path used by build-test.lock.yml) - Replace the duplicate unconditional assignment with the correct conditional version that was already present below it (from PR #1303) Tests: - should not leak GITHUB_API_URL to agent when api-proxy is enabled with envAll - should pass GITHUB_API_URL to agent when api-proxy is NOT enabled with envAll See: github/gh-aw#20875 --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> * fix: restore GITHUB_API_URL in agent container when api-proxy is enabled (#1420) * Initial plan * fix: restore GITHUB_API_URL in agent container when api-proxy is enabled Root cause: commit 5a56789 excluded GITHUB_API_URL from the agent container when api-proxy is enabled, based on the incorrect theory that its presence would cause the Copilot CLI to route token exchange through api.github.com with the placeholder token. Evidence from CI logs: successful runs (worktree-audit-observability) had GITHUB_API_URL present and worked; all failing runs lacked it and failed immediately with "Authentication failed" after ~1.2 seconds. The Copilot CLI needs GITHUB_API_URL to locate the GitHub API. Its Copilot-specific calls (token exchange, inference) already route through COPILOT_API_URL → api-proxy regardless of GITHUB_API_URL being set. Fix: - Remove EXCLUDED_ENV_VARS.add('GITHUB_API_URL') from api-proxy block - Change conditional GITHUB_API_URL assignment to unconditional - Update test to expect GITHUB_API_URL present even with api-proxy enabled Co-authored-by: lpcox <15877973+lpcox@users.noreply.github.com> Agent-Logs-Url: https://github.com/github/gh-aw-firewall/sessions/db4a1afe-02b9-43f2-bfae-41febbcbc8b5 --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: lpcox <15877973+lpcox@users.noreply.github.com> --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Copilot <198982749+Copilot@users.noreply.github.com> Co-authored-by: lpcox <15877973+lpcox@users.noreply.github.com>
