Look up RISC-V Security Horizontal Committee related specifications, including ratified and unratified/development specs. Activate for questions about RISC-V security specifications, memory isolation, memory encryption or confidential computing, I/O isolation, secure interrupts, trusted debug, and control-flow integrity including Zicfilp and Zicfiss.
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
# RISC-V Security HC Specification Lookup ## Rule Do not answer RISC-V Security HC specification-status or source-link questions from memory. First check the bundled specification index and, for current status, verify against the official sources listed there. ## Primary Reference Read `references/security-hc-specifications.md` when the user asks about: - memory isolation: PMP, Smepmp, SPMP, Smmtt, Worlds, Smpmpmt - memory encryption or confidential computing: Security Model, CoVE/AP-TEE, HAC, crypto - I/O isolation: IOMMU, IOPMP, CoVE with I/O - secure interrupts: AIA, PLIC, CLIC, NMI/double-trap related privileged extensions - trusted debug: Debug, external debug security, trigger delegation - control-flow integrity: Zicfilp, Zicfiss, Smcfilp, Smcfiss, shadow stacks ## Status Sources - Ratified specs: `https://riscv.org/specifications/ratified/` and the official RISC-V docs library. - Development specs: `https://riscv.org/specifications/` -> "VIEW DEVELOPMENT SPECS", backed by `https://riscv.github.io/adm-spec-dashboard/latest.csv`. - If GitHub access is blocked in this environment, run network commands through `bosc-ipv6`, for example: ```bash …

How to install
mdr add openxiangshan/xiangshanlab/riscv-security-hc-spec@sha256:43f14e8e33b0b1f3The line at the top of this page pins the label git:20260721.1f8fa49, 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.
