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 | $0.00066 | $0.00700 |
| Opus 5 | $0.00033 | $0.00350 |
| Sonnet 5 | $0.00013 | $0.00140 |
| Haiku 4.5 | $0.00007 | $0.00070 |
Grade A, and why
connectivity-ble 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 Connectivity: BLE
Implement robust, low-power Bluetooth Low Energy applications using Zephyr's industry-standard BLE stack.
Core Workflows
1. BLE Fundamentals
Set up advertising, define GATT services, and manage connections.
- Reference: ble_fundamentals.md
- Key Tools:
BT_GATT_SERVICE_DEFINE,bt_le_adv_start,BT_CONN_CB_DEFINE.
2. Send-When-Idle Pattern
Optimize radio usage by bundling data and transmitting only during idle periods.
- Reference: send_when_idle.md
- Key Tools:
k_work_delayable, Workqueues, SMF integration.
3. Power Optimization
Fine-tune intervals and connection parameters for maximum battery life.
- Reference: power_optimization.md
- Key Tools:
bt_le_conn_param, Advertising intervals, PHY selection.
Quick Start (Advertising)
CONFIG_BT=y
CONFIG_BT_PERIPHERAL=y
#include <zephyr/bluetooth/bluetooth.h>
void start_simple_adv(void) {
bt_enable(NULL);
bt_le_adv_start(BT_LE_ADV_CONN_NAME, NULL, 0, NULL, 0);
}
Professional Patterns (Wireless Design)
- Aggressive Latency: Increase peripheral latency to allow the radio to stay off longer during quiet periods.
- Decoupled Messaging: Use Zbus to feed data into the BLE module, keeping the radio logic separate from the application logic.
- Idle Bundling: Use the "Send-When-Idle" pattern specifically to reduce the number of wake-ups for the radio controller.
Automation Tools
- ble_timing_helper.py: Convert advertising/connection intervals from ms to BLE timing units.
Examples & Templates
- gatt_service_template.c: Starter custom GATT service definition.
Validation Checklist
- Device advertises with expected name/flags and is discoverable by a BLE scanner.
- Central can connect, exchange GATT data, and disconnect without stack errors.
- Configured connection parameters are reflected after negotiation.
- Send-When-Idle flow batches traffic instead of transmitting every sample immediately.
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.

connectivity-ble is a skill published in the GitHub repository beriberikix/zephyr-agent-skills (63 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 66 tokens to every session and 700 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.
