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 | $0.00354 | $0.03315 |
| Opus 5 | $0.00177 | $0.01657 |
| Sonnet 5 | $0.00071 | $0.00663 |
| Haiku 4.5 | $0.00035 | $0.00331 |
Grade A, and why
rdk-multimedia scanned grade A with 0 findings 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 5d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RDK Multimedia Hardware Pipeline (codec / capture / scale / display)
This skill moves raw pixel streams between on-board hardware units: sensor in → ISP tuned → scaled → VPU/JPU encoded/decoded → pushed out to HDMI/MIPI. It does not cover model inference (→ rdk-device) or wrapping any of this into a ROS node (→ rdk-ros).

rdk_doc):docs/07_Advanced_development/03_multimedia_development/*anddocs/03_Basic_Application/06_multi_media_sp_dev_api/RDK_X5/*. S-series (rdk_s_doc):docs/07_Advanced_development/03_multimedia_development/{01_S100,02_multimedia_application,03_S600_multimedia_application}/*. Every spec below was re-verified against these files; numbers nobody could confirm are flagged in the reference's "Unverified" section.
The one thing that matters most
X-series and S-series are two different multimedia stacks — do not map one onto the other. The X-series VPS/VOT vocabulary (HB_VPS_*, HB_VOT_*, sp_dev) does not exist on the S-series; the S-series uses Camsys/PYM/GDC + MediaCodec + IDE/IDU instead. Confirm the board family first, then pick the matching API column. A user who pastes HB_VOT_* code on an S600 is on the wrong stack entirely.

| Stage | X3 (Bernoulli2) / X5 (Bayes-e) / Ultra (Bayes) | S100 / S100P / S600 (Nash) |
|---|---|---|
| Capture | VIN = SIF/MIPI in + ISP + LDC/DIS/DWE | VIN = CIM + MIPI + LPWM + VCON, then ISP |
| Scale / crop / rotate | VPS (IPU scale/crop/rotate + PYM + GDC) | PYM (shrink/ROI) + GDC (geometric correct); YNR is a separate stage |
| Video codec | VENC / VDEC → VPU (H264/H265) | CODEC → VPU, under MediaCodec subsystem |
| Image codec | JPU (JPEG/MJPEG) | JPU (JPEG/MJPEG), under MediaCodec |
| Display | VOT → HDMI / MIPI / BT1120, max 1080P@60 | IDE / IDU → MIPI DSI / MIPI CSI2 Device |
| Easy user-space API | sp_dev (/app/cdev_demo, sp_*) |
/app/multimedia_samples (HB_* / MediaCodec) |
| Bind modules | HB_SYS_Bind / HB_SYS_SetVINVPSMode / sp_module_bind |

What ships with it
3 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-multimedia is a skill published in the GitHub repository D-Robotics/moss (142 stars, last pushed 9d ago), licensed MIT. It adds 354 tokens to every session and 3,315 once invoked, about $0.0018 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
