field-power-and-connectivity-triager

field-power-and-connectivity-triager is a skill for Claude Code from wedsamuel1230/arduino-skills. It costs 54 tokens per session (727 once invoked), scanned A, original, MIT.

A troubleshooting guide for projects that work from USB power but fail when powered through their intended battery or supply path. It examines voltage drops, current peaks, regulators, wiring, Wi-Fi startup, and brownouts.

In plain words
What is it for?
Use it to investigate brownouts, field-only resets, unstable sensors, failed Wi-Fi startup, and problems with battery, VIN, or 3V3 power paths.
Why use it?
It helps distinguish power-delivery faults from software faults when a project resets, becomes unstable, or loses connectivity in the field.

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 A, and why

field-power-and-connectivity-triager scanned grade A with 0 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Field Power And Connectivity Triager

Use this skill when the project works on the bench but breaks when powered the way it will be used in the real world. Apply it to any board or load whose voltage/current path is uncertain; the ESP32 examples are common cases, not a claim that the same limits apply to every board.

Resources

  • references/power-path-triage.md - USB vs VIN vs 3V3 diagnosis workflow
  • references/wifi-and-peak-current.md - WiFi startup, brownout, and current-peak behavior
  • references/measurement-checklist.md - what to measure before blaming the code
  • ../../docs/board-support/uno-r4-family.md - Uno R4 family board caveats where relevant

When to Use

Use this skill when the request includes:

  • "works on USB but not on my power supply"
  • WiFi connects on the bench but not in deployment
  • field-only resets, brownouts, or sensor instability
  • suspected regulator or wiring-path weakness
  • battery, VIN, or 3V3 supply-path questions

Workflow

  1. Reproduce the split:
    • USB works
    • intended power path fails
  2. Open references/power-path-triage.md to classify the supply path.
  3. If WiFi or radio startup is involved, open references/wifi-and-peak-current.md.
  4. Capture actual measurements from references/measurement-checklist.md before assuming the failure is in user code.
  5. If the target is Uno R4 WiFi, open ../../docs/board-support/uno-r4-family.md and keep the connectivity-side hardware split explicit.

Core Rules

  • "Works on USB" is evidence about the power path, not proof the code is sound.
  • WiFi startup current peaks are first-class suspects on ESP32-class boards.
  • Diagnose the supply path before tuning network code blindly.
  • Treat sensor instability under field power as a possible power-integrity issue until measurements say otherwise.
  • Do not use nominal voltage or an idle current reading as proof of peak-current safety; compare the measured load path with the board and component limits.

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.
