Port of OpenHands/OpenHands#14284. The LLM model badge in the conversation header was constrained to max-w-[150px] with an inner `truncate`, which cut off long model identifiers such as `litellm_proxy/claude-sonnet-4-5-20250929` to `litellm_proxy/cl…`. Drop the width cap and inner truncate, and apply `whitespace-nowrap` to the outer span so the full name renders inline. Also adds scripts/record-demo.mjs - a small playwright recorder used to capture the verification GIF under .pr/issue-135/ - and updates the existing test to assert the un-truncated structure. Closes #135. Co-authored-by: openhands <openhands@all-hands.dev>

/**
|
|
* Record a short demo of agent-canvas for PR GIFs.
|
|
*
|
|
* Usage:
|
|
* node scripts/record-demo.mjs <flow> <output-webm>
|
|
*
|
|
* Convert the resulting webm to GIF with:
|
|
* ffmpeg -i <output>.webm \
|
|
* -vf "fps=10,scale=960:-1:flags=lanczos,split[s0][s1];\
|
|
* [s0]palettegen=max_colors=128[p];\
|
|
* [s1][p]paletteuse=dither=bayer:bayer_scale=4" \
|
|
* -loop 0 <output>.gif
|
|
*
|
|
* `npm run dev` from this repo must already be running. By default the
|
|
* recorder hits `http://localhost:12000`; override with `DEMO_BASE_URL` when
|
|
* the frontend is exposed via a remote host (e.g. an All Hands work URL),
|
|
* otherwise the browser-side calls to the agent-server will fail with CORS.
|
|
*
|
|
* Flows:
|
|
* - full-model-name : open home → click "New Conversation" → wait for the
|
|
* conversation header → hover the un-truncated model
|
|
* badge so the tooltip is visible at the end of the
|
|
* recording.
