verify — Headless Terminal App Verification Recorder

Drive a kitty-graphics terminal app headlessly in a pty and produce a recorded video, timeline and checks summary as the deliverable.

Dev & CodingAdvanced★ 922⑂ 44AI score 7/10Last updated: Aug 11, 2026

What it does

  • Runs the app inside a pty with no real terminal: the harness sets TERM=xterm-kitty, pixel window dimensions via TIOCSWINSZ, and answers the 1016 mouse-mode probe.
  • Scripts input with Driver: keys, text, click, press/drag/release, move, wheel — each with a description that becomes the video caption bar and a timeline entry.
  • Recorder captures every emitted frame, encodes an mp4, and writes summary.html with a pass/fail checks table plus named stills.
  • Ends by opening the summary with pixel open file:///tmp/verify-runs/<name>-<stamp>/summary.html — that page is the deliverable.
  • Documents real gotchas: take coords from d.frame_size (the engine rounds down to the cell grid), send ESC as kitty CSI-u, drags need all three press/drag/release events, file args must be absolute paths.

Who it's for

  • Developers building TUI/terminal apps that paint via the kitty graphics protocol and want visual regression checks without a live terminal.
  • Teams that need a verification report showing what was tested and why, not a pile of loose PNGs.
  • Projects that ship the tools/verify-recorder harness, i.e. this repo's layout.

Examples

  1. Verify wheel panning keeps the cursor anchored: launch → pump → wheel 3× at center → assert frame count grew → still("after-scroll") → open summary.
  2. Verify drag selection: send press, drag, release separately and check no stray click fires at the release position.
  3. Capture hover styling: finish the interaction with a move, then assert decoded pixel colors via recorder.png_read(...).

  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the .claude/skills/verify folder from the GitHub repo zenbu-labs/terminal-browser into my ~/.claude/skills/verify/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/zenbu-labs/terminal-browser.git && mkdir -p ~/.claude/skills/verify && cp -r terminal-browser/.claude/skills/verify/* ~/.claude/skills/verify/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Clone the repo: git clone https://github.com/zenbu-labs/terminal-browser.git
  2. Create the skill folder: mkdir -p ~/.claude/skills/verify
  3. Copy the skill in: cp -r terminal-browser/.claude/skills/verify/* ~/.claude/skills/verify/
  4. Keep the clone — the skill depends on the tools/verify-recorder package inside the repo; note its absolute path.
  5. Build the app under test first (e.g. cargo build to produce engine/target/debug/...; for Node apps run npm install in the package dir).
  6. Make sure ffmpeg (video encoding) and the pixel command (opening the summary) are available.
  7. Restart Claude Code and ask it to "verify this app". Artifacts land in /tmp/verify-runs/<name>-<stamp>/summary.html.
