termlens skillA

termlens is agent-read markdown (skill) from vyncint/termlens: Write, fix or review headless terminal tests for a Rust CLI or TUI (ratatui, crossterm, cursive, plain println) with the termlens crate — spawn the real binary in a PTY, wait on the rendered screen without sleeping, snapshot it with insta, assert on cells and styles. Use whenever a test spawns a terminal program, whenever a terminal test is flaky, sleeps or times out, and whenever someone asks how to test a TUI end to end..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add vyncint/termlens/termlens@git:20260905.0907161
Exact content
mdr add vyncint/termlens/termlens@sha256:aa74eff1954875b7

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
