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 | $0.00085 | $0.04206 |
| Opus 5 | $0.00043 | $0.02103 |
| Sonnet 5 | $0.00017 | $0.00841 |
| Haiku 4.5 | $0.00009 | $0.00421 |
Grade A, and why
chipsec scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo mkdir -p "$CHIPSEC_DIR/logs" Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Chipsec - UEFI Firmware Static Analysis
You are helping the user perform static security analysis of UEFI/BIOS firmware dumps using Intel's chipsec framework. This skill focuses exclusively on offline analysis capabilities that do not require kernel driver access or root privileges.
Tool Overview
Chipsec is Intel's Platform Security Assessment Framework. For static analysis of firmware dumps, it provides:
- EFI executable inventory generation with cryptographic hashes
- Detection of known UEFI malware and vulnerabilities
- Firmware structure decoding and extraction
- NVRAM/UEFI variable extraction
- SPI flash descriptor parsing
- Baseline comparison for change detection
Prerequisites
One-Time Setup (Fix Logging Permission)
Chipsec writes into a logs/ directory inside its install location. Create it once. The Python version in the path varies by system, so derive the path instead of hardcoding it:
CHIPSEC_DIR="$(find /usr/lib/python3*/site-packages ~/.local/lib/python3*/site-packages -maxdepth 1 -name chipsec -type d 2>/dev/null | head -1)"
sudo mkdir -p "$CHIPSEC_DIR/logs"
sudo chmod 777 "$CHIPSEC_DIR/logs"
Verify Installation
chipsec_main --version
Core Commands
All static analysis commands use these flags:
-i: Ignore platform check (required for offline analysis)-n: No kernel driver (required for static analysis)
1. Malware and Vulnerability Scan (Primary Use)
Scan firmware for known threats including UEFI rootkits and SMM vulnerabilities:
chipsec_main -i -n -m tools.uefi.scan_blocked -a <firmware.bin>
Detected Threats:
| Threat | Description | Reference |
|---|---|---|
| HT_UEFI_Rootkit | HackingTeam commercial UEFI rootkit | McAfee ATR |
| MR_UEFI_Rootkit | MosaicRegressor APT UEFI implant | Kaspersky |
| LoJax | First UEFI rootkit found in the wild (Sednit/APT28) | ESET |
| ThinkPwn | SystemSmmRuntimeRt SMM code execution vulnerability | cr4.sh |
| FirmwareBleed | SMM Return Stack Buffer stuffing vulnerability | Binarly |
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.
- 3d ago First seen · 536 lines · 85 tokens per session scan A 6be648b84397
chipsec is a skill published in the GitHub repository BrownFineSecurity/iothackbot (819 stars, last pushed 3mo ago), licensed MIT. It adds 85 tokens to every session and 4,206 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
