Flash the FPGA on an HSB board connected to an NVIDIA devkit. Supports HSB Lattice boards (FPGA versions 2407, 2412, 2507, 2510) and Leopard Imaging VB1940 "all-in-one" cameras (FPGA versions 2507, 2510). Uses release-specific YAML manifests and board-type-specific program commands. Lattice and VB1940 commands must never be mixed.

Requires /hsb-setup

Evaluation Report

Evaluation of the hsb-flash skill before publication through NVSkills-Eval.

This benchmark summarizes 3-Tier Evaluation from NVSkills-Eval results for the skill. The goal is to document whether the skill is safe, discoverable, effective, and useful for agents before it is published for broader workflow use.

Evaluation Summary

  • Skill: hsb-flash
  • Evaluation date: 2026-05-30
  • NVSkills-Eval profile: external
  • Environment: local
  • Dataset: 3 evaluation tasks
  • Attempts per task: 2
  • Pass threshold: 50%
  • Overall verdict: FAIL

Agents Used

  • claude-code
  • codex

Metrics Used

Reported benchmark dimensions:

  • Security: checks whether skill-assisted execution avoids unsafe behavior such as secret leakage, destructive commands, or unauthorized access.
  • Correctness: checks whether the agent follows the expected workflow and produces the correct final output.
  • Discoverability: checks whether the agent loads the skill when relevant and avoids using it when irrelevant.
  • Effectiveness: checks whether the agent performs measurably better with the skill than without it.
  • Efficiency: checks whether the agent uses fewer tokens and avoids redundant work.

Underlying evaluation signals used in this run:

  • security (Security): checks for unsafe operations, secret leakage, and unauthorized access.
  • skill_execution (Skill Execution): verifies that the agent loaded the expected skill and workflow.
  • skill_efficiency (Efficiency): checks routing quality, decoy avoidance, and redundant tool usage.
  • accuracy (Accuracy): grades final-answer correctness against the reference answer.
  • goal_accuracy (Goal Accuracy): checks whether the overall user task completed successfully.
  • behavior_check (Behavior Check): verifies expected behavior steps, including safety expectations.
  • token_efficiency (Token Efficiency): compares token usage with and without the skill.

Test Tasks

The benchmark dataset contained 3 evaluation tasks:

  • Positive tasks: 3 tasks where the skill was expected to activate.
  • Negative tasks: 0 tasks where no skill was expected.
  • Unlabeled tasks: 0 tasks where positive/negative intent could not be inferred.

Task composition is derived from the evaluation dataset when possible. Entries with expected_skill set are treated as positive skill-activation cases, while entries with expected_skill: null are treated as negative activation cases.

  • HIGH DUPLICATE/duplicate: Duplicate content found within references/phase-details.md: "#### Steps" in references/phase-details.md (lines 123-133) vs "#### Steps" in references/phase-details.md (lines 144-156) vs "#### Steps" in references/phase-details.md (lines 163-171) vs "#### Steps" in references/phase-details.md (lines 195-205) vs "#### Steps" in references/phase-details.md (lines 213-222) vs "#### Single-step flashing procedure" in references/phase-details.md (lines 788-797) (references/phase-details.md:123)

Publication Recommendation

The skill should be reviewed before NVSkills-Eval publication. Skill owners should address the findings above and rerun NVSkills-Eval to refresh this benchmark.

  • Gen Agent Trust Hub3mo

    This skill facilitates FPGA firmware flashing on NVIDIA devkits. It is assessed as MEDIUM risk because it features an autonomous self-updating mechanism that programmatically modifies its own instruction file (SKILL.md) based on external data fetched from GitHub. It also uses SSH for remote command execution and downloads firmware bitstreams from both vendor-owned and well-known services.
