speed-loop SKILL.md skillA
speed-loop from useburner/burner is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add useburner/burner/speed-loop@git:20261002.cce481fPins git:20261002.cce481f in mdr.lock. Pin the fingerprint instead.

Make burner's phone commands faster without breaking them - bench, trace, change, verify, compare, repeat. Use for any performance work on bin/burner, the u2 or scrcpy helpers, or recipes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# The speed loop
Every speedup must ship in the package (first install or `burner update`).
Nothing hand-tuned on one phone or one computer.
## One round
Run these on a machine that reaches the phone: Muse's computer, or the
dev machine (see tools/README.md, "Benching from the dev machine").
```
burner update # or git pull in a checkout
bash tools/loop.sh # bench -> verify -> compare with last round
```
`loop.sh` runs a warm-up pass ("cold" column), then 3 timed passes, and
saves the results to `run/bench-history.jsonl`. Then it runs
`tools/verify.py` (scroll distance, a fresh read after a scroll, row taps,
dialog refusal, landscape taps, unique screenshot names), and
`tools/benchcmp.py`, which fails on anything 20% and 300ms slower or newly
failing. A red round is not pushed on top of.
## Finding where the time goes
```
python3 tools/tracesum.py --clear
BURNER_TRACE=json burner tap "Search settings"
python3 tools/tracesum.py --last 1
```
The waterfall shows adb calls, every fixed `sleep`, the u2 helper's RPCs
(dump, tap, shot) and "unaccounted" time. `tracesum --clear` also stops the

How to install
mdr add useburner/burner/speed-loop@sha256:6352ab5e0de3e2dbThe line at the top of this page pins the label git:20261002.cce481f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
