validating-tpm-measured-boot-attestation SKILL.md skillA
validating-tpm-measured-boot-attestation from adriannoes/awesome-agentic-ai is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add adriannoes/awesome-agentic-ai/validating-tpm-measured-boot-attestation@v1.0Pins v1.0 in mdr.lock. Pin the fingerprint instead.

Verify TPM PCRs and measured-boot and remote-attestation integrity.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Validating TPM Measured Boot and Attestation
> **Legal Notice:** Perform TPM operations only on systems you own or are authorized to assess. Some operations (clearing the TPM, taking ownership, defining NV indices) are destructive or can lock the device. This skill is for defensive integrity verification and authorized assessment.
## Overview
A Trusted Platform Module (TPM 2.0) is a hardware root of trust that supports **measured boot**: each stage of the boot chain hashes ("measures") the next stage and *extends* that measurement into a Platform Configuration Register (PCR) before handing off control. PCRs cannot be set arbitrarily — they can only be extended (`new = hash(old || measurement)`), so the final PCR value is a tamper-evident summary of everything that executed. The TCG firmware profile assigns specific meanings: UEFI firmware code/config measure into **PCR 0–7** (PCR 7 specifically captures Secure Boot policy), bootloaders measure the kernel into **PCR 8–9**, and Linux IMA measures executables into **PCR 10**.

How to install
mdr add adriannoes/awesome-agentic-ai/validating-tpm-measured-boot-attestation@sha256:4e48b2d1150ed9a9The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
