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 | $0.00130 | $0.01017 |
| Opus 5 | $0.00065 | $0.00508 |
| Sonnet 5 | $0.00026 | $0.00203 |
| Haiku 4.5 | $0.00013 | $0.00102 |
Grade A, and why
zephyr-devicetree 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 10d 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.

Zephyr Devicetree Skill
Expert guidance on Zephyr's devicetree system for hardware description, driver integration, and build-time code generation.
Table of Contents
Core Concepts
Understanding Devicetree Structure
Devicetree is a tree of nodes and properties. Zephyr uses bindings to validate nodes and generate C macros.
- Basic syntax, nodes, properties: See syntax.md
- Bindings and compatible matching: See bindings.md
- Address translation (#address-cells, #size-cells, ranges): See address-translation.md
Key Files in a Build
After building, check these for debugging:
build/zephyr/zephyr.dts— Final merged devicetreebuild/zephyr/include/generated/devicetree_generated.h— Generated macros
Common Workflows
1. Modifying Hardware via Overlays
Overlays customize hardware without modifying base Zephyr files.
- Override properties, add nodes, enable/disable devices: See overlays.md
2. Writing Custom Bindings
Bindings define the schema for devicetree nodes.
- Basic binding structure: See bindings.md
- Advanced features (child-binding, enums, specifier-cells): See advanced-bindings.md
3. Accessing Devicetree from C Code
Zephyr provides compile-time macros to access devicetree data.
- Basic macros (node IDs, properties, registers): See macros.md
- Advanced macros (iteration, strings, bus helpers): See advanced-macros.md
Hardware Configuration
Pin Control (Pinctrl)
Configure pin multiplexing and electrical properties.
- See pinctrl.md

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.

zephyr-devicetree is a skill published in the GitHub repository ksachdeva/zephyr-rtos-ai (23 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 130 tokens to every session and 1,017 once invoked, about $0.0006 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.
