Playwright CLI Issue Triage

You run unattended in the Issue triage workflow of microsoft/playwright-cli. First read the shared guide, $AGENT_GUIDES_DIR/triage.md, a copy of microsoft/playwright/.github/actions/run-agent/guides/triage.md, and then CLAUDE.md, both in full. The guide says how to triage an issue in any Playwright repo. CLAUDE.md says how to build, test and lint this one. This file covers what neither has: where the code is, the checkouts, how to run a published version, and the outcome that this repo adds, a fix in microsoft/playwright.

Where the code is

This repo is the npm package @playwright/cli: playwright-cli.js with its update check, skillCheck.js, the README, the skill in skills/playwright-cli/ and some tests of the packaged CLI. package.json pins the alpha of playwright and playwright-core that the package runs. The CLI is in microsoft/playwright, in packages/playwright-core/src/tools/: cli-client/ has the commands and their options, cli-daemon/ has the daemon that keeps the browser open between commands, and backend/ has the tools that the commands run. Most bugs and most feature requests are fixed there.

Fix a bug here only when the cause is in a file that this repo owns. skills/playwright-cli/ is a copy of packages/playwright-core/src/tools/skills/playwright-cli/, which scripts/update.js refreshes on a roll, so its fix is upstream too.

The checkouts

$REPO_DIR is the checkout of microsoft/playwright-cli that the guide describes. npm ci ran in it, and the browsers of the pinned version are installed. The CLI uses Google Chrome from the runner image by default. When it is missing, install it with npx playwright install chrome. The clone is shallow: run git fetch --unshallow --tags origin in it before you need its history.

$PLAYWRIGHT_DIR is a clone of microsoft/playwright at the tip of main, next to $REPO_DIR. npm ci and npm run build ran in it, and Chromium, Firefox and WebKit are installed. It is tip-of-tree for this repo: reproduce there, as a test in its tests/mcp/cli-*.spec.ts, with the cli fixture of tests/mcp/cli-fixtures.ts. npm run test-playwright-cli runs those tests. Read its AGENTS.md in full before you write the test. It says how to build, test and lint it. The clone has the full history, without file contents until git needs them, so git log and git tag --contains work there.

The pinned version is older than tip-of-tree. npm view playwright-core@<alpha> gitHead prints the upstream commit that an alpha was built from.

Fix in microsoft/playwright

When the fix is in $PLAYWRIGHT_DIR, follow the Fix section of the guide there, in place of $REPO_DIR: create the branch fix-<n> from main in $PLAYWRIGHT_DIR, put the regression test in its tests/mcp/cli-*.spec.ts, build and lint as its AGENTS.md says, and commit in its convention, for example fix(cli): .... Then leave the proposal in $OUTPUT_DIR/upstream-fix/ in place of $OUTPUT_DIR/fix/, with the same files:

• fix.patch: the output of git diff --binary main HEAD in $PLAYWRIGHT_DIR.
• pr-body.md: as the guide says. The Fixes line has the full URL of the issue, Fixes https://github.com/microsoft/playwright-cli/issues/<n>, so that the PR closes the issue in this repo.
• proposal.json: as the guide says. Write it last.

The publish job opens the draft PR in microsoft/playwright. The revision workflow of that repo addresses the review. Leave one proposal: fix/ or upstream-fix/, not both. Do not change package.json here to pick up the fix. It reaches @playwright/cli with the next roll.

Check the linked PRs in both repos. A PR in microsoft/playwright links this issue with its full URL or as microsoft/playwright-cli#<n>. Search there too: repo:microsoft/playwright is:pr "playwright-cli/issues/<n>" and repo:microsoft/playwright is:pr "playwright-cli#<n>". A PR there from the team or from microsoft-playwright-automation is a team PR. Verify a PR there in $PLAYWRIGHT_DIR.

Already fixed means that tip-of-tree passes and the pinned version fails. The fix reaches users with the next roll. Find the upstream PR with git -C $PLAYWRIGHT_DIR log <gitHead of the pinned alpha>..main -- packages/playwright-core/src/tools, and name it in the note.

Published versions

To run a published version, for example the version of the reporter or to bisect, create $SCRATCH_DIR/playwright-cli-<n>/<version>/ and run there:

npm init -y
npm i @playwright/cli@<version>
npx playwright-cli --help

The fixtures of the repo are not available there. Run the condensed repro as npx playwright-cli commands, or as a script that spawns them, in that directory. Serve the page from a data: URL or from http.createServer() in the script. Run npx playwright-cli close-all when you are done, so that no daemon stays open.

npm view @playwright/cli@<version> dependencies.playwright-core prints the alpha of a release. Match a regression to upstream commits with git -C $PLAYWRIGHT_DIR log <good gitHead>..<bad gitHead> -- packages/playwright-core/src/tools.

PRs from third parties

Do not run a PR in this repo that changes package.json, package-lock.json, scripts/, .github/, .azure-pipelines/ or .claude/. For a PR in microsoft/playwright, the list in $PLAYWRIGHT_DIR/.claude/skills/playwright-triage/SKILL.md applies.
