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 | $0.00060 | $0.00772 |
| Opus 5 | $0.00030 | $0.00386 |
| Sonnet 5 | $0.00012 | $0.00154 |
| Haiku 4.5 | $0.00006 | $0.00077 |
Grade A, and why
specialized 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 Specialized Hardware & Reliability
Integrate complex peripherals and build resilient systems that recover gracefully from unexpected failures.
Core Workflows
1. LVGL GUI Development
Build sophisticated graphical user interfaces for LCD and TFT displays.
- Reference: lvgl_gui.md
- Key Tools: Widgets, Styles, Double Buffering,
native_simsimulator.
2. Audio I2S & Codecs
Implement high-quality digital audio streaming and codec management.
- Reference: audio_i2s.md
- Key Tools:
CONFIG_I2S, DMA streaming, Ping-pong buffering.
3. Watchdog & Reliability
Ensure your system never hangs in the field using hardware watchdog timers.
- Reference: watchdog_reliability.md
- Key Tools:
wdt_feed(), Windowed watchdog, Health checks.
4. Fault Injection & Resilience
Test your system's ability to recover from unexpected software and hardware errors.
- Reference: fault_injection.md
- Key Tools: Chaos testing,
k_oops(), Reset reason diagnostics.
Quick Start (Watchdog Feed)
# Enable watchdog support
CONFIG_WATCHDOG=y
// Feed the dog in your main loop
while (1) {
// Perform application work
wdt_feed(wdt_dev, wdt_channel);
k_sleep(K_MSEC(1000));
}
Professional Patterns (Reliability & UX)
- Safe Boot Animation: Use a simple, non-interactive LVGL screen to show system status while critical subsystems (e.g., cloud connectivity) are initializing.
- Zero-Pop Audio: Always use volume ramping when starting or stopping I2S streams to protect hardware and improve user experience.
- Bitmask Health Monitoring: Use a bitmask to track the health of all background threads; the watchdog monitor only feeds the timer if ALL bits are set periodically.
Automation Tools
- watchdog_window_check.py: Verify feed interval timing against watchdog window constraints.
What ships with it
7 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.

specialized is a skill published in the GitHub repository beriberikix/zephyr-agent-skills (63 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 60 tokens to every session and 772 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.
