verify SKILL.md skillA
verify from zenbu-labs/terminal-browser is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add zenbu-labs/terminal-browser/verify@git:20260721.c3339dcPins git:20260721.c3339dc in mdr.lock. Pin the fingerprint instead.

Drive an engine app headlessly in a pty, record a video of the whole verification, and open a summary page (video + timeline + checks) with pixel open.
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
Apps here render via the kitty graphics protocol, so they can be verified
without a real terminal. Every verification is **recorded**: the harness in
`tools/verify-recorder/` captures every frame the app emits, overlays your
inputs (click ripples, caption bar), encodes a video, and generates a summary
page. Do not hand-roll one-off pty scripts that only dump PNGs.
## Writing a verification
Write a driver script (in /tmp is fine) using the checked-in package:
```python
import sys
sys.path.insert(0, "<repo>/tools/verify-recorder")
from driver import Driver
from recorder import Recorder
rec = Recorder("wheel-pan", title="Wheel pan keeps cursor anchored")
d = Driver(["<repo>/engine/target/debug/typing"], rec,
cols=120, rows=32, xpixel=1200, ypixel=800)
d.pump(3.0) # pump between actions so frames arrive
rec.check("app painted", d.frame_size is not None, f"{d.frame_size}")
w, h = d.frame_size # REAL framebuffer size — always use this
d.text("hello", "type into editor") # every input takes a description
d.click(w // 2, h // 3, "select the note") # mouse coords are pixels (1016 mode)
…Read the whole file at its exact version.
How to install
mdr add zenbu-labs/terminal-browser/verify@sha256:c300f9c8b032a617The line at the top of this page pins the label git:20260721.c3339dc, 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.
