Description: <br>
Guides developers through hands-on DOCA Comch work on a host + BlueField pair, covering PCIe control-plane messaging setup, server/client role selection, slow-path and fast-path data transfer, capability queries, connection callbacks, and DOCA_ERROR debugging. <br>
This skill is ready for commercial/non-commercial use. <br>

License/Terms of Use: <br>
Apache 2.0 AND CC-BY-4.0 <br>
Use Case: <br>
Developers and engineers building applications that consume the DOCA Comch C library to exchange control or data messages between a host process and a BlueField DPU agent over PCIe. <br>

Global <br>
Requirements / Dependencies: <br>
Requires API Key or External Credential: [No] <br> Credential Type(s): [None] <br>
Do not include secrets in prompts/logs/output; use least-privilege credentials; rotate keys as appropriate. <br>
Known Risks and Mitigations: <br>
Risk: Review before execution as proposals could introduce incorrect or misleading guidance into skills. <br> Mitigation: Review and scan skill before deployment. <br>

Skill Output: <br>
Output Type(s): [Configuration instructions, Code, Shell commands, Analysis] <br> Output Format: [Markdown with inline C code blocks and bash commands] <br> Output Parameters: [1D] <br> Other Properties Related to Output: [None] <br>
Evaluation Agents Used: <br>
- Claude Code (
aws/anthropic/bedrock-claude-opus-4-8) <br> - Codex (
openai/openai/gpt-5.5) <br>
Evaluation Tasks: <br>
Evaluated against 4 internal evaluation tasks (3 positive skill-activation, 1 negative) using the Skill Evaluator external profile in a k8s-sandbox environment. <br>
Evaluation Metrics Used: <br>
Reported benchmark dimensions: <br>
- Security: Checks whether skill-assisted execution avoids unsafe behavior such as secret leakage, destructive commands, or unauthorized access. <br>
- Correctness: Checks whether the agent follows the expected workflow and produces the correct final output. <br>
- Discoverability: Checks whether the agent loads the skill when relevant and avoids using it when irrelevant. <br>
- Effectiveness: Checks whether the agent performs measurably better with the skill than without it. <br>
- Efficiency: Checks whether the agent uses fewer tokens and avoids redundant work. <br>
Underlying evaluation signals used in this run: <br>
security: Checks for unsafe operations, secret leakage, and unauthorized access. <br>skill_execution: Verifies that the agent loaded the expected skill and workflow. <br>skill_efficiency: Checks routing quality, decoy avoidance, and redundant tool usage. <br>accuracy: Grades final-answer correctness against the reference answer. <br>goal_accuracy: Checks whether the overall user task completed successfully. <br>behavior_check: Verifies expected behavior steps, including safety expectations. <br>
