+name: display-test
+description: Test an ESPHome display driver on a real panel with a camera. Use when a task asks to verify a display (LCD, e-paper, OLED, RLCD) on hardware, check orientation/rotation, partial updates, colours, contrast, or that text and shapes render correctly. Covers finding the USB port, flashing a test pattern, capturing the panel with any camera, and reading the photo.
+allowed-tools: Read, Write, Edit, Bash, Glob, Grep
+---
+
+# Display testing with a camera
+
+Point a camera at the panel to get visual evidence that a driver renders correctly. Any camera
+and capture tool works; this skill covers the common ones. `$SKILL` below is this directory
+(`.agents/skills/display-test`).
+
+## Ask before using a camera
+
+A camera can show people and rooms, not only the panel. Before the first capture, ask the user
+for permission and for which camera to use. List the cameras the host has (the commands below
+show how), name the one you intend to use, and wait for the user to confirm it. Do not pick a
+camera yourself, and do not fall back to another camera if the chosen one fails; ask again.
+
+The permission covers this session and the camera the user named. Ask again for a different
+camera or in a new session. If the user declines, stop and report that the display was not
+checked visually.
+
+## Capturing a frame
+
+Grab a still image, skipping the first few frames so auto-exposure and white balance settle.
+Read the JPEG with the Read tool; the image is shown visually.
+
+### macOS
+
+The bundled Swift tool uses AVFoundation and avoids the frame-grabbing problems some USB
+cameras have with other tools:
+
+```bash
+mkdir -p /tmp/camsnap /tmp/display-test
+swiftc -O "$SKILL/scripts/camsnap.swift" -o /tmp/camsnap/camsnap
+/tmp/camsnap/camsnap <camera-name-substring> /tmp/display-test/after.jpg 30
+```
+
+The camera argument is a case-insensitive substring of the name AVFoundation reports. If it does
+not match, the tool lists the cameras it found, so a run with a name that matches nothing lists
+the cameras without capturing. Use a substring that matches only the camera the user approved.
+It creates the output directory if needed and reports encoding or write errors on stderr. Other
+options include `ffmpeg` with `avfoundation` input, `imagesnap`, or Photo Booth's still capture.
+
+### Linux
+
+Use `ffmpeg` with the v4l2 input, `fswebcam`, or `v4l2-ctl`. With `ffmpeg`, `-ss 2` after the
+input discards the first two seconds of frames while exposure settles:
+
+```bash
+mkdir -p /tmp/display-test
+ffmpeg -f v4l2 -i /dev/video0 -ss 2 -frames:v 1 -y /tmp/display-test/after.jpg
+# or
+fswebcam -d /dev/video0 --skip 10 /tmp/display-test/after.jpg
+```
+
+List devices with `v4l2-ctl --list-devices`.
+
+### Windows
+
+Use `ffmpeg` with the DirectShow input (`-ss 2` skips the first frames, as on Linux), or any
+camera application that can save a still image:
+
+```powershell
+mkdir C:\temp -Force | Out-Null
+ffmpeg -f dshow -list_devices true -i dummy   # find the device name
+ffmpeg -f dshow -i video="<device name>" -ss 2 -frames:v 1 -y C:\temp\after.jpg
+```
+
+### Camera caveats
+
+- The board may sit at an angle. Do not trust absolute pixel positions or aspect ratios from the
+  photo; judge orientation, ordering and approximate spacing, using the corner markers as
+  references.
+- Reflections or a glossy cover can brighten one side. Capture again if a region is unclear.
+- A moving pattern is caught at an arbitrary phase. Take several captures, or use a static marker
+  per position.
+
+## Board and port
+
+Find the port; names change on every replug:
+
+```bash
+python3 "$SKILL/../hardware-test/scripts/ports.py"
+```
+
+Native-USB ESP32-S3/C3/C6/H2 boards show up as `USB JTAG/serial debug unit` and need
+`logger: hardware_uart: USB_SERIAL_JTAG`.
+
+## Test pattern
+
+Write a scratch config outside the checkout. Use one `name:` per board and include:
+
+- a white background, a black border and a filled square at the centre, drawn in the first
+  update (full-window check and scale);
+- a 60x20 bar near each corner, one bar per later update with `auto_clear_enabled: false`, so
+  each bar is written by its own partial window. The bars are wider than tall, which shows a
+  90 or 270 degree rotation; the corners exercise the window alignment;
+- a 20x20 square under the left end of the top-left bar, drawn in the same update, which marks
+  the top-left corner and shows a 180 degree rotation or a mirrored image.
+
+Use `Color::BLACK` and `Color::WHITE` in lambdas. Do not use the old `COLOR_OFF`/`COLOR_ON`
+constants; black must mean black.
+
+A ready template is in `$SKILL/templates/display-pattern.yaml`. Substitute the display platform,
+pins and (for a driver with fonts) a font. The marker pattern needs no font.
+
+## Build, flash, capture
+
+Run from the worktree under test so `python -m esphome` imports the checkout, not an installed
+copy:
+
+```bash
+cd <worktree>
+python3 -c "import esphome; print(esphome.__file__)"   # must print the worktree path
+PYTHONUNBUFFERED=1 python3 -m esphome compile /tmp/display-test/display-pattern.yaml
+PYTHONUNBUFFERED=1 python3 -m esphome upload /tmp/display-test/display-pattern.yaml \
+  --device /dev/cu.usbmodemXXXX
+sleep 6   # boot plus a few update intervals
+<capture command> /tmp/display-test/after.jpg
+```
+
+The device path differs by OS and host; use the path printed by `ports.py`. If the USB console
+wedges during flashing (esptool `No serial data received`), replug the board and retry. A board
+powered only by a battery may need the USB cable for flashing; the panel keeps its image when
+power is removed, which is useful for checking that an image is bistable.
+
+## What to check
+
+1. **Orientation**: the extra square sits under the bar in the expected top-left corner. If it is
+   in another corner, the image is rotated or mirrored. Test `rotation:` values with the same
+   pattern. The logical width and height swap at 90 and
+   270 degrees, so the 60x20 corner bars should then appear taller than wide on the physical
+   panel.
+2. **Coverage**: the border touches all four edges, with no dead rows or columns at the edges.
+3. **Partial updates**: with `auto_clear_enabled: false`, draw one marker per update. Each should
+   appear exactly at its requested position with no smearing, offset or mirrored placement.
+   Include all four corners.
+4. **Text and contrast**: sharp glyphs, correct polarity (black text on white, not inverted), no
+   ghosting from the previous frame.
+5. **Speed**: if the driver logs transfer sizes, check that a full refresh and a partial window
+   take the expected times.
+
+Record the build commit, board, config, and the captured image path when reporting results.
+
+## When a partial update looks wrong
+
+Take a marker-only capture before assuming the mapping is wrong: the camera's perspective makes
+absolute positions deceptive. If markers land in mirrored positions, the controller's address
+order (`MADCTL` MX/MY/MV) or the RAM block mapping is inverted for the window; verify the
+full-frame path separately, then fix the window computation.
+
+## Add findings
+
+Add new capture tools, panel quirks, or recovery steps here so the next session starts ahead.

+listed id with `?detail=all` and one retry, because the ESP8266 async server occasionally leaves a request unanswered
+within 5 s). The web ids are `domain/Name`, not object ids, and `/event/<name>` has no GET handler (404 on every
+build). `mqtt_norm.py` drops the `dev` block (compile time) and the `NAME/debug` topic (heap probe), so a clean run
+differs in nothing. `dump_config` prints icons and device classes only for some domains; button, event and
+binary_sensor icons never appear there.
+
+Found with this flow on 2026-10-21: since #19577 every ESP8266 `web_server` build that lists a cover, climate, lock,
+valve, update, alarm_control_panel or water_heater entity reboots with `Exception (3) LoadStoreErr` in
+`json::linked(const char *)` (the ROM `strlen` on a flash address), fixed by #21316. The cover in the template keeps
+that path covered; before #21316 is merged, apply its one line change to both trees or the web_server comparison
+cannot run.
