Walkthrough

The PR extends the net-edge examples to support the Claude Code agent by introducing five new evaluation configuration files for different test scenarios, updating the README with Claude Code instructions, modifying MCP configuration to include additional server settings, and enhancing the Claude Code agent with GCP credential validation and improved command defaults.

Changes

Cohort / File(s) Summary
Documentation
examples/net-edge/README.md
Restructured to add "Running with Claude Code" section alongside existing "Running with Codex" section; updated paths and examples to reference eval_*.yaml configurations for both agent types.
Claude Code Agent Evaluations
examples/net-edge/claude-code-agent/eval_1_selector-mismatch.yaml, eval_2_nxdomain.yaml, eval_3_networkpolicy.yaml, eval_4_reencrypt-tls.yaml, eval_5_loadbalancer.yaml
Five new evaluation configuration files added, each defining a builtin.claude-code agent evaluation with MCP config reference, task set pointing to corresponding test scenario, and assertions requiring 1–20 netedge tool calls.
MCP Configuration
examples/net-edge/mcp-config.yaml
Extended netedge MCP server invocation with additional argument flag (-s) pointing to mcpserver.yaml configuration file.
Agent Implementation
pkg/agent/claude_code.go
Added os package import; enhanced ValidateEnvironment to check GCP credentials and emit warnings for Vertex AI authentication; updated GetDefaults RunPrompt with new command-line flags (--dangerously-skip-permissions, --output-format stream-json, --verbose) and -p shell flag usage.

examples/net-edge/claude-code-agent/eval_2_nxdomain.yaml (3)

1-6: LGTM! Correct use of builtin Claude Code agent.

The configuration correctly uses builtin.claude-code as the agent type, which aligns with the maintainer's instruction to leverage the builtin Claude agent rather than adding a custom implementation.


7-9: LGTM! File references are correctly structured.

The relative paths to the shared MCP config and task definition are appropriate for the directory structure.


10-14: LGTM! Assertions follow the established pattern.

The assertions appropriately verify that the netedge server is used and constrain the tool call count. The range of 1-20 tool calls is consistent with other eval files in this PR.

1-4: Update description to reflect dual-agent support.

The title and description focus on "Codex GPT-5 coding agent" but the document now covers both Codex and Claude Code agents. Consider making this more generic or mentioning both agents.

Proposed update
 # NetEdge Scenario 1 (Service Selector Mismatch)
 
 Evaluate the NetEdge gen-mcp server **Route → Service selector mismatch** scenario with the `gevals`
-framework and the Codex GPT-5 coding agent.
+framework using Codex GPT-5 or Claude Code agents.

26-62: Consider adding Claude Code prerequisites.

The prerequisites section only covers Codex-specific requirements (API key, config.toml, etc.). Consider adding a separate subsection for Claude Code prerequisites, such as:

  • Claude CLI installation and authentication
  • Any required environment variables or configuration

85-87: Use agent-agnostic language in shared workflow description.

Line 86 states "The Codex agent must diagnose and repair the mismatch" but this description applies to both Codex and Claude Code workflows since it describes what happens after running either eval.

Proposed update
 `setup.sh` deploys the hello workload, then intentionally breaks the Service selector so the Route loses its
-endpoints. The Codex agent must diagnose and repair the mismatch, after which `verify.sh` confirms the selector
+endpoints. The agent must diagnose and repair the mismatch, after which `verify.sh` confirms the selector
 and endpoints are healthy. Results are written to `gevals-netedge-selector-mismatch-out.json` by default.
examples/net-edge/claude-code-agent/agent.yaml (1)

59-83: Consider potential race condition in cleanup trap.

The cleanup function receives $? as an argument, but the trap is set as trap 'cleanup $?' EXIT. If any command in the cleanup function itself fails (before set -euo pipefail triggers), the original exit status could be lost. The trap - EXIT at line 80 followed by exit "${exit_status}" is the correct pattern, but consider using a subshell or capturing the status earlier.

Additionally, the .kube removal at line 70-72 is good for security, but the debug directory could still contain sensitive data in claude-code-home/.config/gcloud.

🔎 Consider also removing gcloud credentials from debug output
       if [[ -d "${DEBUG_DIR}/claude-code-home/.kube" ]]; then
         rm -rf "${DEBUG_DIR}/claude-code-home/.kube"
       fi
+      if [[ -d "${DEBUG_DIR}/claude-code-home/.config/gcloud" ]]; then
+        rm -rf "${DEBUG_DIR}/claude-code-home/.config/gcloud"
+      fi
gevals-claude-code-netedge-selector-mismatch-out.json (1)

1-6: Consider removing/anonymizing absolute paths and sensitive data from example output.

The taskPath field (line 4) contains an absolute path including a username (/home/alsyed/gevals/...). Additionally, the taskOutput field contains session IDs, cluster URLs, and IP addresses that are specific to a particular test run. If this file is intended as example output for documentation, consider:

  1. Replacing the absolute path with a relative path or placeholder
  2. Sanitizing or replacing real cluster URLs and IPs with example values
gevals-claude-code-netedge-networkpolicy-block-out.json (1)

1-6: Same path/data sanitization concern as other output files.

Contains absolute path with username in taskPath. Consider sanitizing for public documentation.

gevals-claude-code-netedge-nxdomain-host-out.json (1)

1-6: Same path sanitization concern applies.

The taskPath contains an absolute path with username. Consider anonymizing for the example output.

14-17: Documentation structure looks good.

The layout section correctly documents the new claude-code-agent directory and eval_*.yaml pattern for both agent types.


63-83: Clear documentation for both agent workflows.

The separation into "Running with Codex" and "Running with Claude Code" sections makes it easy for users to follow the appropriate workflow.

examples/net-edge/claude-code-agent/eval_5_loadbalancer.yaml (1)

1-15: All referenced files in eval_5_loadbalancer.yaml exist and are properly configured:

  • agent.yaml
  • ../mcp-config.yaml
  • ../tasks/loadbalancer-missing/loadbalancer-missing.yaml
examples/net-edge/mcp-config.yaml (1)

8-9: The -s flag for genmcp run is undocumented; verify it's supported in gen-mcp.

The configuration uses an undocumented -s flag that does not appear in the official genmcp CLI documentation or in the README.md example (which only shows -f). Additionally, the referenced files (mcpfile.yaml and mcpserver.yaml) are in an external ../gen-mcp/ directory outside this repository and cannot be verified here.

examples/net-edge/claude-code-agent/agent.yaml (5)

9-15: LGTM on prerequisite validation.

The script uses set -euo pipefail for strict error handling and properly validates the jq dependency before proceeding.


32-48: Kubeconfig handling preserves cluster access correctly.

The logic properly prioritizes an explicit KUBECONFIG environment variable, falling back to copying the original HOME's .kube directory. The 2>/dev/null || true pattern gracefully handles missing files.


50-56: GCP credential preservation for Vertex AI authentication.

The conditional copying of ~/.config/gcloud when GOOGLE_APPLICATION_CREDENTIALS is not set ensures Vertex AI authentication works in the temporary HOME context.


95-100: Model override implementation looks correct.

The optional CLAUDE_MODEL environment variable allows flexibility in model selection without requiring changes to the agent configuration.


102-108: The tee command does not mask the claude exit code; pipefail is already enabled.

Line 11 sets set -euo pipefail, which ensures the pipeline claude "${CLAUDE_ARGS[@]}" 2>&1 | tee -a returns the claude command's exit code, not tee's. Combined with set -e, any failure from claude will trigger the cleanup trap. Exit code handling is correct.

Likely an incorrect or invalid review comment.

gevals-claude-code-netedge-selector-mismatch-out.json (1)

20-149: Call history structure captures MCP tool interactions correctly.

The callHistory section properly records tool calls with timestamps, request/response data, and success status. This provides good traceability for debugging evaluation scenarios.

gevals-claude-code-netedge-networkpolicy-block-out.json (1)

7-19: Assertion results structure is well-defined.

The assertionResults object with toolsUsed, minToolCalls, and maxToolCalls provides clear pass/fail indicators for evaluation criteria.

gevals-claude-code-netedge-nxdomain-host-out.json (1)

84-146: Multi-tool call history demonstrates DNS probing capability.

The call history shows both inspect_route and probe_dns_local tool invocations, validating the agent's ability to use multiple MCP tools for diagnosis. The DNS probe correctly queries public DNS (8.8.8.8) for A records.

Remove the error log file or add it to .gitignore.

The netedge-selector-mismatch-error.txt file in the repository root appears to be a captured error output from a local test run (GCP credential failure). Unlike the related .json evaluation output files which are documented in examples/net-edge/README.md, this .txt error file is not referenced in any documentation and is likely an accidental commit. Either remove it from the repository and add *.txt patterns (or this specific file) to .gitignore, or if it's intentional example documentation, move it to the examples/net-edge/ directory and document its purpose in the README.

(e.g., *.txt or this filename) to prevent future accidental commits, or move the
file into examples/net-edge/ and update examples/net-edge/README.md to document
its purpose, then commit the move and .gitignore change accordingly.

Hey @Thealisyed is there a reason the builtin claude code agent doesn't work for your use case?

Hi @Cali0707!
Brett asked me to port this using the same pattern as his Gemini agent PR (#69) for consistency across agents.
Hmm that is a possibility that we could alternatively try and tweak the builtin claude code agent instead as that would be a smaller change.
I'll let @bentito weigh in on which approach he prefers.

I didn't know there was a built in claude code agent!! 😄 @Thealisyed just give us a set of evals that uses the built in Claude agent then, I think

27-36: Consider adding a timeout for the gcloud command.

The validation logic helpfully checks for GCP credentials needed for Vertex AI, but the gcloud auth application-default print-access-token command could potentially hang or take significant time if gcloud is misconfigured.

🔎 Suggested improvement with timeout
 	// Check for GCP credentials (for Vertex AI users)
 	if os.Getenv("GOOGLE_APPLICATION_CREDENTIALS") == "" {
 		if _, err := exec.LookPath("gcloud"); err == nil {
 			// gcloud exists, check if ADC is configured
 			cmd := exec.Command("gcloud", "auth", "application-default", "print-access-token")
+			cmd.Timeout = 5 * time.Second  // Add reasonable timeout
 			if err := cmd.Run(); err != nil {
 				fmt.Fprintf(os.Stderr, "Warning: No GCP credentials found. If using Vertex AI, run 'gcloud auth application-default login'\n")
 			}
 		}
 	}

Alternatively, use context.WithTimeout for more control:

 	// Check for GCP credentials (for Vertex AI users)
 	if os.Getenv("GOOGLE_APPLICATION_CREDENTIALS") == "" {
 		if _, err := exec.LookPath("gcloud"); err == nil {
 			// gcloud exists, check if ADC is configured
+			ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
+			defer cancel()
-			cmd := exec.Command("gcloud", "auth", "application-default", "print-access-token")
+			cmd := exec.CommandContext(ctx, "gcloud", "auth", "application-default", "print-access-token")
 			if err := cmd.Run(); err != nil {
 				fmt.Fprintf(os.Stderr, "Warning: No GCP credentials found. If using Vertex AI, run 'gcloud auth application-default login'\n")
 			}
 		}
 	}

1-151: Consider whether evaluation output files should be committed to the repository.

This file contains detailed execution traces and outputs from running evaluations. A few considerations:

  1. Repository size: These JSON output files are quite large and will accumulate over time
  2. Absolute paths: Line 4 contains an absolute path /home/alsyed/gevals/... with a username, which might not be intended for the repository
  3. Maintenance: Output files may become stale as code evolves

Consider one of these approaches:

  • Move output files to a separate examples/artifacts directory with a note they're for reference
  • Add *-out.json to .gitignore and document how to generate them locally
  • Keep only one example output file per scenario type for documentation purposes

If keeping these files is intentional for documentation/examples, that's fine—just wanted to flag for consideration.

🔇 Additional comments (9)
examples/net-edge/claude-code-agent/eval_5_loadbalancer.yaml (1)

1-14: LGTM! Well-structured evaluation configuration.

The eval configuration follows the established pattern for Claude Code agent evaluations. The use of builtin.claude-code aligns with the maintainer's direction from PR comments, and the tool call constraints (1-20) are appropriate for the load balancer missing scenario.

pkg/agent/claude_code.go (2)

5-5: LGTM! Necessary import for environment variable checks.

The os package is correctly imported to support the new GCP credential validation logic.


52-52: Verify the necessity of --dangerously-skip-permissions flag.

The --dangerously-skip-permissions flag bypasses safety checks, which could have security implications. While this may be necessary for automated eval execution in a controlled environment, ensure this is intentional and documented.

The flag name suggests it's meant for specific scenarios where user prompts are not required. Confirm that:

  1. The eval sandbox environment is sufficiently isolated
  2. The evaluated code is trusted or the environment is disposable
  3. This aligns with the security model for automated evaluations

If this is standard practice for eval execution, consider documenting this in the README or eval configuration guide.

examples/net-edge/claude-code-agent/eval_1_selector-mismatch.yaml (1)

1-14: LGTM! Clean eval configuration.

The eval definition is well-structured and correctly uses the builtin.claude-code agent type as directed in the PR discussion. The assertions and path references are appropriate.

examples/net-edge/claude-code-agent/eval_4_reencrypt-tls.yaml (1)

1-14: LGTM! Consistent eval structure.

This eval definition maintains consistency with the other Claude Code eval configurations in this PR while correctly referencing the reencrypt-tls scenario task.

examples/net-edge/README.md (3)

14-16: LGTM! Clear documentation of the new structure.

The layout section accurately reflects the addition of Claude Code eval configurations and helpfully notes that they use the builtin agent.


62-71: LGTM! Clear separation of Codex instructions.

The section rename and path update appropriately distinguish Codex-specific instructions from the new Claude Code section.


78-80: The documentation is already correct and clearly conveys that GCP authentication is conditional. The code confirms this: the Claude Code agent checks for GOOGLE_APPLICATION_CREDENTIALS and runs gcloud auth application-default print-access-token, but only issues a warning if credentials are missing—it does not fail. The agent continues to execute without GCP credentials, relying on Claude CLI's default authentication methods. The README's "If using Vertex AI" language appropriately indicates this is optional.

netedge-selector-mismatch-error.txt (1)

1-9: Remove this error log file from the repository.

This file contains error output from a local test run (GCP credential failure) and should not be committed. As previously noted, this appears to be an accidental inclusion.

Please remove this file and consider adding a .gitignore pattern for error log files:

*-error.txt
*.log

Likely an incorrect or invalid review comment.

Summary:

  - Add Claude Code agent configuration for running NetEdge eval scenarios
  - Include 5 eval definitions matching the Gemini agent structure. 6th eval needs more investigation
  - Update README
