At a glance
Flash ESPHome firmware to physical EspControl devices. An agent skill from jtenniswood/esphome-media-player.
- The user says Flash Devices
- SKILL.md covers Default Target, Network Flash - Default, USB Flash and Other Devices, plus 2 more sections
- Calls docker and python3
- Flash the device
What it does
Flash Devices is an agent skill from jtenniswood/esphome-media-player. Flash ESPHome firmware to physical EspControl devices. Use when the user says "Flash Devices", "$flash-devices", "flash the device", "flash the S3", "deploy over IP", "OTA flash", "flash over USB", or wants local firmware uploaded to a connected or networked ESPHome device. Defaults to flashing the Guition ESP32-S3 4848S040 device over IP at 192.168.6.100.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Development, covering Embedded systems and File uploads and storage. It works with ESP32. The repository describes itself as: Touch screen display for showing cover artwork from any Home Assistant media entity.
When your agent uses it
- The user says Flash Devices
- Flash the device
- Wants local firmware uploaded to a connected
- Networked ESPHome device
Example prompts
- “Flash Devices”
- “$flash-devices”
- “flash the device”
- “/flash-devices”
Requirements
- Python 3
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit 8ab172b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
dockerpython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Flash Devices loads about 1.1k tokens when it runs. Until then it costs about 93 tokens; SKILL.md has 439 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 439 words (~1,143 tokens).
“Flash the current workspace firmware to a physical ESPHome device. Default to the Guition ESP32-S3 4848S040 over Wi-Fi at 192.168.6.100 unless the user names another device, gives another IP address, or explicitly asks for USB.”
