sticky-device

sticky-device is a skill for Claude Code from varo6/reTerminal-sticky-skill. It costs 93 tokens per session (1,012 once invoked), scanned A, original, MIT.

A development reference for the Seeed Studio reTerminal Sticky, a small ESP32-S3 device with a touch-sensitive electronic-ink screen. It covers native ESP-IDF firmware and the supported no-code ESPHome route.

In plain words
What is it for?
It is for building and flashing Sticky firmware, using its screen and touch controls, assigning hardware pins, managing sleep and power, and publishing apps.
Why use it?
It helps avoid device-specific mistakes involving power startup, screen orientation, touch input, and firmware delivery.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

sticky-device 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/fetch_sticky_sources.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

reTerminal Sticky

Seeed Studio reTerminal Sticky: a magnetic ESP32-S3 e-ink note device. 3.97" 800x480 monochrome ePaper with 4-level grayscale, capacitive touch, 750 mAh battery.

Firmware is native ESP-IDF v5.4 / target esp32s3 (C/C++). ESPHome is the supported no-C path. Apps are distributed by flashing whole firmware images — there is no on-device app sandbox or multi-app runtime.

Read this first for any firmware task

Two rules cause most first-time failures on this device:

  1. Latch power on at boot. The device powers off unless firmware drives the power-hold GPIOs within the first moments of app_main(). See references/esp-idf-dev.md.
  2. The panel is natively 800x480 landscape. Your logical canvas orientation is a choice you implement with a rotation in the pixel-write path. Pick one and keep touch coordinates in the same space. See references/display.md.

Where to look

Task File
Pin map, buses, part numbers, electrical/physical specs references/hardware.md
Toolchain, project skeleton, sdkconfig.defaults, build/flash, power latch, NVS, deep sleep references/esp-idf-dev.md
ePaper driver API, refresh modes, rotation, ghosting, partial-update strategy references/display.md
Touch/GT911 gestures, buttons, IMU, SHT40, RTC, mic, buzzer, fuel gauge, SD references/peripherals.md
Publishing to Sticky Playground: integration.json, manifest, CI, review flow references/playground-registry.md
Existing firmware projects, ESPHome/Home Assistant, official docs, where the wiki is references/ecosystem-and-docs.md

Getting known-good driver sources

The registry holds a complete, buildable ESP-IDF app (sticky-2048) whose drivers are the practical reference implementation for this board: seeed_epaper (SSD1677 panel), gt911 (touch), bq27220 (fuel gauge), plus sticky_display / sticky_touch / sticky_buzzer / sticky_ai_button wrappers.

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.
