SkillSpector: 5 findings, up to high
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 →
- high Supply Chain · line 130 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00140 | $0.02369 |
| Opus 5 | $0.00070 | $0.01184 |
| Sonnet 5 | $0.00028 | $0.00474 |
| Haiku 4.5 | $0.00014 | $0.00237 |
Grade B, and why
testbench-wifi 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -s "$TESTBENCH_URL/api/info" # confirm before anything else How it starts
The opening of the file, as written. The whole thing — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ESP32 WiFi & Provisioning
Base URL: $TESTBENCH_URL — see Step 0
Step 0: Point at a bench
There are several benches and their addresses move, so nothing here writes one
down. $BENCH is not usable either — a container cannot resolve mDNS.
Discover the bench and export its URL:
export TESTBENCH_URL=$(sudo python3 .claude/skills/esp-idf-handling/discover-testbench.py \
--url --name <bench-hostname>)
curl -s "$TESTBENCH_URL/api/info" # confirm before anything else
--url refuses to guess when more than one bench answers, so --name is
required whenever a second bench is powered on. TESTBENCH_URL is the same
variable pytest --wt-url falls back to.
Operating Modes
The testbench has two WiFi operating modes:
| Mode | wlan0 usage | WiFi endpoints |
|---|---|---|
| wifi-testing (default) | Test instrument (AP/STA/scan) | Active |
| serial-interface | Joins WiFi for additional LAN | Disabled |
# Check current mode
curl $TESTBENCH_URL/api/wifi/mode
# Switch to wifi-testing mode
curl -X POST $TESTBENCH_URL/api/wifi/mode \
-H 'Content-Type: application/json' \
-d '{"mode": "wifi-testing"}'
# Switch to serial-interface mode (joins a WiFi network)
curl -X POST $TESTBENCH_URL/api/wifi/mode \
-H 'Content-Type: application/json' \
-d '{"mode": "serial-interface", "ssid": "MyNetwork", "pass": "password"}'
Endpoints
Request and response shapes: FSD Appendix D.4, plus
/api/enter-portal in D.2.
AP and STA are mutually exclusive — one radio. Starting the AP drops any STA association and vice versa, so a test that needs both must sequence them.
WiFi AP (Access Point)
# Start AP
curl -X POST $TESTBENCH_URL/api/wifi/ap_start \
-H 'Content-Type: application/json' \
-d '{"ssid": "TestAP", "pass": "testpass123", "channel": 6}'
# Check AP status and connected clients
curl $TESTBENCH_URL/api/wifi/ap_status
# Stop AP
curl -X POST $TESTBENCH_URL/api/wifi/ap_stop
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.
- 11d ago First seen · 234 lines · 140 tokens per session scan B 7f19e6dbe8f7
testbench-wifi is a skill published in the GitHub repository SensorsIot/Embedded-AI-Harness (173 stars, last pushed 1mo ago), licensed MIT. It adds 140 tokens to every session and 2,369 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.
