passport-debug

passport-debug is a skill for Claude Code, Codex from FoloToy/ai-passport. It costs 49 tokens per session (783 once invoked), scanned A, original, MIT.

A troubleshooting workflow for diagnosing runtime failures in FoloToy AI Passport firmware from logs and symptoms. Firmware is the software that runs directly on a device.

In plain words
What is it for?
It is for investigating reboots, stack faults, watchdog resets, blank text, black screens and missing audio, and applying a fix only when requested.
Why use it?
It separates observed evidence from guesses and prevents diagnosis from being treated as permission to edit, rebuild or flash the device.

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

passport-debug 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 1mo 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.

Diagnose Firmware Failures

Locate the affected checkout and read AGENTS.md. Start with git status --short --branch. Determine whether the user wants an explanation or a fix: diagnosis does not authorize edits, rebuilding, flashing, or pushing. The supplied log may come from another firmware; the current checkout is not automatically its source.

Establish the evidence

  • Record the symptom, reproducible user action, first relevant error, reset/ exception type, task, firmware version, and ELF SHA shown in the log. Request only missing information that would change the conclusion; do not request credentials, raw device QR content, or a whole private environment dump.
  • Distinguish observation, likely cause, and unverified hypothesis. A stack pointer outside the reported task bounds is direct evidence of a stack fault; the exact allocating/calling function still requires matching symbols.
  • For the current application's code, inspect the relevant headers and implementation. Use docs/hardware-design/AI_HARDWARE_DEVELOPMENT_GUIDE.md for the matching symptom, not a generic ESP32 board's pins or assumptions.

Match symbols before decoding addresses

For a saved gate build, verify its bundle with python3 tools/archive_firmware.py verify <archive-directory>. Compare the panic/boot ELF identity with app_elf_sha256 in its manifest. A truncated log hash must match a unique candidate; ask for the complete identity if ambiguous. For other builds, obtain the ELF that produced the flashed image and evidence of its identity. A similar Git version or a later rebuild is not a substitute.

Only after matching, use the activated toolchain's riscv32-esp-elf-addr2line -pfiaC -e <matching.elf> <addresses> for the panic PC, return address, and credible trace frames. Raw stack words are not all return addresses. If symbols are unavailable, explain what the log itself establishes and request the matching build artifacts; do not invent file/line locations or rebuild the current source and call it the old firmware.

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.

passport-debug is a skill published in the GitHub repository FoloToy/ai-passport (646 stars, last pushed 2d ago), licensed MIT. It adds 49 tokens to every session and 783 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-17.
