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 | $0.00109 | $0.03088 |
| Opus 5 | $0.00055 | $0.01544 |
| Sonnet 5 | $0.00022 | $0.00618 |
| Haiku 4.5 | $0.00011 | $0.00309 |
Grade A, and why
esphome-config-helper 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 5d 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.

ESPHome Configuration Helper
Rapid ESPHome configuration generation and troubleshooting skill with ready-to-use templates, GPIO reference guides, and validation utilities.
Purpose
This skill accelerates ESPHome device configuration by providing:
- Quick-start templates for common device types
- GPIO pinout references to prevent conflicts
- Common sensor configurations with wiring diagrams
- Error message lookup and solutions
- Configuration validation workflow
Use this skill for general ESPHome configuration tasks. For ESP32-S3-BOX-3 specific implementations, use the esphome-box3-builder skill instead.
When to Use This Skill
Use this skill when:
- Starting a new ESPHome device configuration
- Adding sensors, switches, or displays to existing configs
- Troubleshooting compilation or runtime errors
- Determining safe GPIO pins for components
- Validating configuration before flashing
Delegate to specialized ESPHome agents for:
- Deep technical questions (esphome-core, esphome-components, etc.)
- Complex automation logic (esphome-automations agent)
- Network troubleshooting (esphome-networking agent)
- ESP32-S3-BOX-3 projects (esphome-box3 agent)
Configuration Templates
Available Templates
Located in templates/ directory:
-
basic-device.yaml- Minimal ESP32 starter- ESP32 platform with WiFi and API
- OTA updates enabled
- Logger and web server
- Use as foundation for custom projects
-
sensor-node.yaml- Temperature/humidity sensor node- DHT22 sensor on GPIO4
- WiFi with fallback AP
- Home Assistant integration
- Use for environmental monitoring
-
relay-switch.yaml- 4-channel relay controller- GPIO control for 4 relays (GPIO23, GPIO22, GPIO21, GPIO19)
- Physical button inputs with interlocks
- Switch entities for Home Assistant
- Use for home automation switching
-
display-node.yaml- Display with sensors- SSD1306 OLED display (128x64, I²C)
- DHT22 temperature/humidity
- Display lambda showing sensor readings
- Use for visual sensor displays
What ships with it
8 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.

esphome-config-helper is a skill published in the GitHub repository nodnarbnitram/claude-code-extensions (16 stars, last pushed 4mo ago), licensed MIT. It adds 109 tokens to every session and 3,088 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.
