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 5.1 | $0.00360 | $0.03833 |
| Opus 5 | $0.00180 | $0.01917 |
| Sonnet 5 | $0.00072 | $0.00767 |
| Haiku 4.5 | $0.00036 | $0.00383 |
Grade B, and why
rdk-board-delegate 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 6d 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 rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
Yes, S600 is covered — but mind the gate: **S600 V5.1.0+ defaults to the Native (`ec_hobot`) EtherCAT driver** (S100 is V4.0.7+). The Native driver is **mutually exclusive with the `hobot_eth_super` gmac driver** — start How it starts

RDK S-Series Heterogeneous Development & Board Delegation
S100/S100P/S600 are not "X-series with more TOPS". They are a single SoC with three heterogeneous compute domains that close the perception→decision→control loop on-chip: CPU (Acore, the "big brain") + BPU (decision) + MCU (the "little brain", hard real-time). The single most important thing to get right is which domain a task belongs to and how the two brains talk — put a millisecond joint loop on the MCU over IPC, never on a Linux RT thread, and never confuse the MCU's remoteproc firmware load with MCU0's fastboot/Xburn flashing.
Scope: RDK S100 / S100P / S600 only (Nash BPU,
.hbmartifacts). X3/X5/Ultra have no MCU subsystem and none of this applies. Sources are the official D-Roboticsrdk_s_docrepo (docs/07_Advanced_development/05_mcu_development,02_linux_development,03_multimedia_development) anddeveloper.d-robotics.cc. Every non-trivial claim was re-verified against those docs.
The three compute domains (the foundation)
| Domain | Hardware | Runs | Typical work | Where you write code |
|---|---|---|---|---|
| "Big brain" CPU (Acore) | A78AE (S100/S100P 6× @1.5/2.0GHz; S600 18× @2.0GHz) | Ubuntu (S100/S100P 22.04 + Humble, S600 24.04 + Jazzy) | ROS2 nodes, AI orchestration, planning | Most user code lives here |
| "Decision" BPU | Nash — 80 TOPS (S100) / 128 (S100P) / 560 (S600, 4× core) | hbm_runtime |
LLM/VLM/detection/segmentation/point cloud | Compile .hbm via hb_compile (see rdk-device) |
| "Little brain" MCU | R52+ (S100 4× / S600 6×, FreeRTOS V10.0.1) | bare FreeRTOS, not Linux | hard real-time joint/motor loops (ms/kHz), IMU pre-proc, CAN | MCU1 firmware (this skill) |
Two facts that catch everyone:
- MCU firmware is not in
apt. You develop MCU1 (open-source business firmware on FreeRTOS), cross-compile a.elf, and load it with Linux remoteproc — no JTAG, no flashing for day-to-day iteration. JTAG / fastboot / Xburn are only for MCU0 (closed-source: boot, power management, OTA). - CAN on S100/S600 lives in the MCU domain via CANHAL, not Linux SocketCAN. (Only X5 is Linux SocketCAN.)
What ships with it
5 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.

rdk-board-delegate is a skill published in the GitHub repository D-Robotics/moss (142 stars, last pushed 10d ago), licensed MIT. It adds 360 tokens to every session and 3,833 once invoked, about $0.0018 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 2026-08-30.
