Embedded-AI-Harness: Skill for Claude Code

.claude/skills/testbench-test-handling/SKILL.md

testbench-test-handling is a skill for Claude Code from SensorsIot/Embedded-AI-Harness. It costs 149 tokens per session (3,626 once invoked), scanned B, original, MIT.

A test workflow for an ESP32 test bench, which is a setup for testing physical ESP32 devices through a web panel and connected hardware.

In plain words
What is it for?
Use it to check preconditions, run test steps one at a time, handle required operator actions such as button presses or cable changes, and record PASS, FAIL, or SKIP results.
Why use it?
It makes every test follow the written specification and records the observed result, not just a pass or fail label.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths.

This is SensorsIot/Embedded-AI-Harness's own configuration. It tells Claude Code how to work on Embedded-AI-Harness itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Embedded-AI-Harness configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is export TESTBENCH_URL=$(sudo python3 .claude/skills/esp-idf-handling/discover-testbench.py \.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

testbench-test-handling scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ESP32 Test Automation

Base URL: $TESTBENCH_URL — see Step 0

The portal and the MQTT broker are always-on infrastructure. A test never starts, stops or restarts them — doing so breaks whatever else is using the bench, and a test that needs a restart to pass is testing the restart.

The execution protocol

Every test case runs in three phases, and the panel shows which one is current so the operator can follow along without a terminal.

Phase Panel shows What happens
Preconditions [TC-100] Preconditions: checking DUT reachable... Verify and establish each precondition from the spec. If the AP is not running, start it. Fail only when a precondition is genuinely unrecoverable.
Execute [TC-100] Step 2: <the step from the spec> Run the spec's steps one at a time, checking the expected result after each.
Result TC-100: PASS / TC-100: FAIL — <what was seen> Record PASS/FAIL/SKIP with the observed value, not just the verdict.

Rules that decide whether a run is worth anything:

  1. The spec is the script. Execute its preconditions, steps and pass criteria as written — not an improved version of them.
  2. Update the panel before each action, never after. The panel is how the operator knows what the bench is doing to the hardware right now.
  3. Record baselines. Where the spec says "record X as X_before", capture it and compare in the result phase.
  4. Generate test credentials per run. A random SSID and password for the test AP proves the DUT used what it was provisioned with, rather than a network it had already cached.
  5. Write the results out. A markdown file with test ID, name, result, details and timestamps — the panel is live state, not a record.

Workflows that span several instruments — provision, reboot, re-provision, soak — are in references/common-workflows.md.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

testbench-test-handling is a skill published in the GitHub repository SensorsIot/Embedded-AI-Harness (173 stars, last pushed 1mo ago), licensed MIT. It adds 149 tokens to every session and 3,626 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
