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 | $0.00092 | $0.01312 |
| Opus 5 | $0.00046 | $0.00656 |
| Sonnet 5 | $0.00018 | $0.00262 |
| Haiku 4.5 | $0.00009 | $0.00131 |
Grade A, and why
zephyr-bluetooth-le 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 Bluetooth LE
Quick Start
- Enable BLE:
CONFIG_BT=yinprj.conf - Choose GAP Role: See GAP Roles section
- Initialize: Call
bt_enable(NULL)inmain() - Define Services: Use GATT macros or built-in services
- Start Advertising/Scanning: Based on role
Core Initialization Pattern
#include <zephyr/bluetooth/bluetooth.h>
#include <zephyr/bluetooth/conn.h>
#include <zephyr/bluetooth/gatt.h>
int main(void)
{
int err = bt_enable(NULL);
if (err) {
printk("Bluetooth init failed (err %d)\n", err);
return 0;
}
/* If using persistent storage */
if (IS_ENABLED(CONFIG_BT_SETTINGS)) {
settings_load();
}
/* Register connection callbacks, start advertising, etc. */
}
GAP Roles
| Role | Kconfig | Description | Key APIs |
|---|---|---|---|
| Peripheral | CONFIG_BT_PERIPHERAL=y |
Connectable advertiser, GATT server | bt_le_adv_start(), bt_gatt_service_register() |
| Central | CONFIG_BT_CENTRAL=y |
Scans and connects, GATT client | bt_le_scan_start(), bt_conn_le_create() |
| Broadcaster | CONFIG_BT_BROADCASTER=y |
Non-connectable advertiser | bt_le_adv_start() with non-conn params |
| Observer | CONFIG_BT_OBSERVER=y |
Passive scanner | bt_le_scan_start() |

Common Patterns
Peripheral (GATT Server)
/* Advertising data */
static const struct bt_data ad[] = {
BT_DATA_BYTES(BT_DATA_FLAGS, (BT_LE_AD_GENERAL | BT_LE_AD_NO_BREDR)),
BT_DATA_BYTES(BT_DATA_UUID16_ALL, BT_UUID_16_ENCODE(BT_UUID_HRS_VAL)),
};
static const struct bt_data sd[] = {
BT_DATA(BT_DATA_NAME_COMPLETE, CONFIG_BT_DEVICE_NAME,
sizeof(CONFIG_BT_DEVICE_NAME) - 1),
};
/* Start connectable advertising */
err = bt_le_adv_start(BT_LE_ADV_CONN, ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd));
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-bluetooth-le is a skill published in the GitHub repository ksachdeva/zephyr-rtos-ai (23 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 92 tokens to every session and 1,312 once invoked, about $0.0005 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.
