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 | $0.00046 | $0.00625 |
| Opus 5 | $0.00023 | $0.00313 |
| Sonnet 5 | $0.00009 | $0.00125 |
| Haiku 4.5 | $0.00005 | $0.00063 |
Grade A, and why
u8g2-integration 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 9d 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.

U8g2 Integration
Overview
Use this skill to integrate U8g2 by proving display controller wiring, bus callbacks, reset timing, buffer mode, and font memory before debugging drawing code. Small display failures are usually port or bus issues first.
When To Use
Use this skill when:
- The user wants U8g2/U8glib-style graphics on OLED/LCD modules.
- The issue involves blank display, wrong orientation, I2C/SPI failures, font size, page buffer mode, or slow refresh.
- The target uses SSD1306, SH1106, ST7565, ST7920, or similar small display controllers.
Do not use this skill for full GUI stacks like LVGL. Use lvgl-integration when widgets and input devices dominate.
First Questions
Ask for:
- Display controller, resolution, interface, address/CS/DC/RST pins, and voltage level.
- MCU, driver/HAL, RTOS/bare-metal model, and U8g2 constructor/setup function.
- Buffer mode: full buffer, page buffer, or 1-page mode.
- Font, text language requirements, and flash/RAM budget.
- Current symptom and whether bus-level signals were measured.
Integration Checklist
-
Confirm hardware path. Check power, reset, I2C/SPI wiring, address, CS/DC pins, and logic levels.
-
Select exact constructor. Controller, resolution, rotation, and interface must match the panel.
-
Implement bus callbacks. Byte and GPIO/delay callbacks must drive I2C/SPI and reset timing correctly.
-
Choose buffer mode. Full buffer is simpler but uses RAM; page mode needs correct drawing loop.
-
Test minimal draw. Draw a box or text with a small font before custom UI.
Common Failures
- SH1106 panel treated as SSD1306.
- I2C address shifted incorrectly.
- Page buffer mode used without first/next page loop.
- Reset pin not toggled or delay too short.
- Font tables exceed flash budget.
- SPI DC/CS pins swapped or not controlled by callbacks.
Verification
Before claiming U8g2 works:
- State controller, resolution, interface, pins, constructor, and buffer mode.
- Confirm bus scan or measured bus traffic when possible.
- Confirm minimal draw and orientation.
- Confirm RAM/flash impact of chosen buffer and fonts.
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.

u8g2-integration is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 625 once invoked, about $0.0002 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 2026-09-03.
