Push content to Boox e-ink tablet for iterative review. Supports multiple annotation rounds — user annotates, agent updates document via update_session tool, tablet reloads.
Render the eink WebView in local Chrome via DevTools MCP. Spawns a kitchen-sink or realistic-scenario session at the tablet viewport, optionally against a fresh `cargo run` server for iterating on `render.rs`. Includes a follow-up flow for verifying the same session on the actual Boox WebView via remote debugging.
Commit eink-bridge changes, bump the nix_dots flake input, and apply via nixos-rebuild. Use after editing skills, harness files, or server code in the eink-bridge repo.
Update the content of an active eink session on the Boox tablet. Use when iterating on a document mid-review without waiting for annotation events.

The HTML report is at android/app/build/reports/jacoco/jacocoTestReport/html/index.html.
The XML report (machine-parseable) is at the same path with .xml extension.
Read the XML or HTML to extract per-class coverage. Key classes to check:
StrokeBuffer — pure data structure, should be near 100%SessionAdapter (statusIcon, formatSessionTime) — pure utility functionsPenOverlay (rawDrawingAction) — pure decision functionMainActivity — Android-coupled, low coverage expected (needs instrumentation tests)Present findings as:
Coverage Summary

Uncovered Areas Needing Tests
For each gap, explain:
main.rs and mock_device.rs are binary entrypoints — low coverage is expected and not worth flagging.MainActivity.kt requires Android instrumentation tests (not JUnit) — flag this as a known gap but don't suggest unit tests for Android framework code.
