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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00025 | $0.02434 |
| Opus 5 | $0.00013 | $0.01217 |
| Sonnet 5 | $0.00005 | $0.00487 |
| Haiku 4.5 | $0.00003 | $0.00243 |
Grade B, and why
validating-tpm-measured-boot-attestation scanned grade B 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 8d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

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.
Two complementary verifications matter. Local validation reads current PCRs (tpm2_pcrread) and replays the TPM event log (tpm2_eventlog on /sys/kernel/security/tpm0/binary_bios_measurements) to confirm the recorded measurements reproduce the live PCR values — proving the log is authentic and revealing exactly what changed if a value drifts from baseline. Remote attestation has the TPM produce a signed quote (tpm2_quote) over selected PCRs using an Attestation Key (AK), with a fresh nonce to prevent replay; a verifier then independently checks the signature and PCR digest (tpm2_checkquote) and compares against a golden/expected value. This lets a server cryptographically establish that a remote machine booted approved firmware and kernel before granting access, sealing secrets, or admitting it to a Zero Trust network.
This skill provides the full tpm2-tools workflow for enrolling an AK, capturing and verifying quotes, replaying event logs, sealing/unsealing data to a PCR policy, and building a golden-value baseline for fleet attestation.
What ships with it
4 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.
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.

validating-tpm-measured-boot-attestation is a skill published in the GitHub repository adriannoes/awesome-agentic-ai (57 stars, last pushed 14d ago), licensed MIT. It adds 25 tokens to every session and 2,434 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
