Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00023 | $0.01039 |
| Opus 5 | $0.00012 | $0.00519 |
| Sonnet 5 | $0.00005 | $0.00208 |
| Haiku 4.5 | $0.00002 | $0.00104 |
Grade A, and why
esp32_crash_review 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.

ESP32 Crash Review
Analyze crash reports, Guru Meditation errors, and panic dumps to determine root cause.
When to Use
- After observing a Guru Meditation error.
- When a device is stuck in a crash-reboot loop.
- When analyzing crash dumps from field devices.
Steps
1. Identify the Exception Type
| Exception | Cause |
|---|---|
LoadProhibited |
Read from invalid memory (often NULL pointer) |
StoreProhibited |
Write to invalid memory |
InstrFetchProhibited |
Tried to execute code from invalid address |
IllegalInstruction |
Stack corruption, code corruption, or invalid function pointer |
IntegerDivideByZero |
Division by zero |
Unaligned |
Unaligned memory access |
2. Extract Key Information
From the panic output, collect:
Guru Meditation Error: Core [0/1] panic'ed ([ExceptionType]).
Exception was unhandled.
Core [N] register dump:
PC : 0x........ PS : 0x........
A0 : 0x........ A1 : 0x........ ...
EXCVADDR: 0x........ ← The address that caused the fault
PC (Program Counter) → Where the crash happened. EXCVADDR (Exception Address) → What address was accessed illegally. A1 → Stack pointer at time of crash.
3. Decode the Backtrace
# Using addr2line
xtensa-esp32-elf-addr2line -pfiaC -e build/project.elf ADDR1 ADDR2 ADDR3
# Using idf.py
idf.py monitor # Automatically decodes backtraces
# Using ESP-IDF monitor with ELF
python -m esp_idf_monitor --port /dev/ttyUSB0 --baud 115200 build/project.elf
4. Analyze Common Patterns
NULL Pointer Dereference
- EXCVADDR:
0x00000000or small value (<0x100) - Cause: Using an uninitialized pointer or a handle that failed to initialize.
- Fix: Add NULL checks before dereferencing.
Stack Overflow
- Signs:
IllegalInstructionorLoadProhibitedwith A1 near the end of stack space. - Cause: Task stack too small, deep recursion, large local variables.
- Fix: Increase task stack size, reduce local buffer sizes, check recursion depth.
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.

esp32_crash_review is a skill published in the GitHub repository agodianel/esp32-claude-workbench (79 stars, last pushed 5mo ago), licensed MIT. It adds 23 tokens to every session and 1,039 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
