Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00445 | $0.03175 |
| Opus 5.5 | $0.00178 | $0.01270 |
| Sonnet 5.5 | $0.00089 | $0.00635 |
| Haiku 4.5 | $0.00044 | $0.00317 |
Grade A, and why
vibe-uiflow 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UIFlow2 → a device with a screen (agent-driven, seconds per iteration)
Companion to
vibe-firmware, not a replacement. That skill is C/ESP-IDF: layered components, pinned Docker builds, OTA. This one is the same philosophy at a different operating point — MicroPython on the M5 stack, where a change reaches the screen in seconds and you give up compile-time checking, tight memory control and OTA to get it. Pick this for a panel-and-buttons device, a bench instrument, a demo, a shape you are still finding. Pickvibe-firmwarewhen you need determinism, power discipline, or to ship a fleet.
Why this operating point exists
The expensive step in firmware is not compiling — it is finding out what the change did. Flash, unplug, look, guess: 30–60 seconds with a human in the loop, which means an agent cannot run it at all. UIFlow2 removes the compile, and the two loops below remove the human. What is left is an agent that can see what it drew.

make check # device loop: compile + upload + selftest on hardware
make probe # what this firmware actually exposes — before you call it
make run # run live, tracebacks come back to the terminal
make deploy # install as main.py, start on power-up
What ships with it
3 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.

vibe-uiflow is a skill published in the GitHub repository luckiday/vibe-hardware (7 stars, last pushed 1mo ago), licensed MIT. It adds 445 tokens to every session and 3,175 once invoked, about $0.0018 per session on Opus 5.5. 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 2026-08-31.
