What is SPI Flash Dump via OpenOCD?

Guidance for reading SPI flash or EEPROM memory through a microcontroller’s SWD or JTAG debug connection using OpenOCD. SPI flash is memory commonly used to store firmware, while OpenOCD is a tool for communicating with debug hardware.

For dumping SPI flash, reading EEPROM, or extracting firmware through an MCU with SWD or JTAG access.

It gives a defined process for extracting firmware or other stored data through a debug interface.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00084	$0.02670
Opus 5.5	$0.00034	$0.01068
Sonnet 5.5	$0.00017	$0.00534
Haiku 4.5	$0.00008	$0.00267

Security

Grade A, and why

SPI Flash Dump via OpenOCD 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 2mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (examples/dump.sh, examples/init_dumper.sh, examples/verify_dump.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
