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 | $0.00051 | $0.00610 |
| Opus 5 | $0.00026 | $0.00305 |
| Sonnet 5 | $0.00010 | $0.00122 |
| Haiku 4.5 | $0.00005 | $0.00061 |
Grade A, and why
build-system 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 11d 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 Build System
Efficiently manage the complex build and configuration stack of Zephyr RTOS.
Core Workflows
1. West Workspace & Manifests
Manage multi-repo projects and dependency allow-lists.
- Reference: west.md
- Key Tools:
west init,west update,west manifest --resolve,name-allowlist.
2. Kconfig Configuration
Tune software features and hardware parameters.
- Reference: kconfig.md
- Key Tools:
west build -t menuconfig, symbol searching (/), help (?).
3. Sysbuild & Multi-Image
Configure complex projects like MCUboot + Application.
- Reference: cmake.md
- Key Tools:
west build --sysbuild,sysbuild.conf.
4. CMake & Project Structure
Core build logic for applications and modules.
- Reference: cmake.md
- Key Tools:
CMakeLists.txt,zephyr_library(),target_sources().
Quick Start (Workspace + Build)
west init -m <manifest-repo-url> zephyr-workspace
cd zephyr-workspace
west update
west build -b native_sim samples/hello_world
Validation Checklist
-
west updateresolves all manifest projects without errors. -
west buildsucceeds for at least one known target board. - Required Kconfig symbols are present in
build/zephyr/.config. -
scripts/find_modules.shreports module names that match the current manifest allow-list.
Automation Tools
- find_modules.sh: Scan your
build/directory to automatically identify which modules you should add to your manifest'sname-allowlist.
Examples & Templates
- west_manifest_template.yml: Minimal starter manifest for west workspaces.
Resources
- References:
west.md: West commands, manifests, and allow-lists.kconfig.md: Project configuration and menuconfig usage.cmake.md: Sysbuild and CMake API integration.
- Scripts:
find_modules.sh: Automated allow-list discovery utility.
- Assets:
west_manifest_template.yml: Base west manifest template.
What ships with it
6 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.

build-system is a skill published in the GitHub repository beriberikix/zephyr-agent-skills (63 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 51 tokens to every session and 610 once invoked, about $0.0003 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.
