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 | $0.00532 |
| Opus 5 | $0.00026 | $0.00266 |
| Sonnet 5 | $0.00010 | $0.00106 |
| Haiku 4.5 | $0.00005 | $0.00053 |
Grade A, and why
zephyr-module 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 Modules
Extend the Zephyr RTOS with reusable, out-of-tree modules that integrate seamlessly with the build system.
Core Workflows
1. Defining a Module
Create the directory structure and metadata required for auto-discovery.
- Reference: module_definition.md
- Key Tools:
zephyr/module.yml,zephyr/Kconfig,zephyr/CMakeLists.txt.
2. West Manifest Integration
Adding your module to a workspace for distribution and versioning.
- Reference: west_integration.md
- Key Tools:
west.yml,west update,west build -t list_modules.
3. Library Wrapping (Glue Code)
Wrapping external C/C++ libraries as Zephyr modules.
- Reference: module_definition.md
- Key Tools:
zephyr_library(),zephyr_include_directories().
Quick Start (module.yml)
build:
cmake: .
kconfig: zephyr/Kconfig
Validation Checklist
-
west updatefetches module source from manifest without conflicts. -
west build -t list_modulesshows the module as discovered. - Module Kconfig options appear and can be enabled in build configuration.
- Module sources are compiled and linked into the target application as expected.
Automation Tools
- module_manifest_check.py: Validate required
build.cmakeandbuild.kconfigfields inmodule.yml.
Examples & Templates
- module_yml_template.yml: Starter module manifest for out-of-tree integration.
Resources
- References:
module_definition.md: Structure and module.yml specification.west_integration.md: Manifest configuration and discovery tools.
- Scripts:

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.

zephyr-module 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 532 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.
