claude-code-plugins

Purpose

This is a check-only setup under the plugin contract's carve-out for external prerequisites
setup can only verify (docs/plugin-philosophy.md, "Setup is explicit and repeatable"). The
plugin owns no consumer-project configuration; its one userConfig option, playwright_core, is
set through Claude Code's plugin settings, never written here. Everything else it needs (ffmpeg,
Node, playwright-core and its Chromium, the Python packages) is installed by the operator, so
there is nothing an apply could conformingly write.

Non-interactive: never prompt. Run the probe, print the table, stop.

check (read-only)

${CLAUDE_PLUGIN_ROOT}/scripts/prereq.py owns every probe, its threshold and its remedy text;
the same rows stop render.py and decode.py with exit 2 when a tool is missing. Run it, do not
restate it:

uv run --with-requirements ${CLAUDE_PLUGIN_ROOT}/requirements.txt python \
  ${CLAUDE_PLUGIN_ROOT}/scripts/prereq.py --playwright-core '${user_config.playwright_core}'

It prints the PASS/FAIL/INFO table with one remediation line per FAIL and exits 1 when any row
fails. An unset playwright_core option (empty, or left as the literal placeholder) is skipped;
a set one gets its own row. Report the table as printed. An INFO on numpy or opencv means a
version other than the pin in ${CLAUDE_PLUGIN_ROOT}/requirements.txt is installed: scripts run,
but statistics may differ from the shipped pack and regression, so say so.

When uv itself is missing, the command above cannot start: report that as the one FAIL, with
the remedy to install uv (https://docs.astral.sh/uv/), and run
python3 ${CLAUDE_PLUGIN_ROOT}/scripts/prereq.py for the tool rows (it needs only the standard
library; numpy and opencv then read FAIL).

Do not install anything, and do not change the playwright_core option.

Gotchas

• The Chromium row launches the browser through capture.mjs --probe, so it takes a few seconds
  and is the one row that proves playwright-core and its browser resolve together.
• A PASS on the Chromium row with an unset option can come from the working directory or a
  playwright-cli install on PATH: capture.mjs owns that lookup order.
