playwright-rollPlaywright Roll is an official skill in microsoft/playwright-dotnet (3k stars). Its SKILL.md is about 1.9k tokens. Licence: MIT.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 3c2b12c. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Shell commands in SKILL.md call:
gitdotnetFrom the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
github.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Playwright Roll loads about 1.9k tokens when it runs. Until then it costs about 13 tokens; SKILL.md has 900 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/playwright-roll/SKILL.md (or your agent's skills folder).Help the user roll to a new version of Playwright. ../../../ROLLING.md contains general instructions and scripts. See also CLAUDE.md for build, test, and architecture details.
Unless the exact version is specified by the user, you need to find the latest version of the driver. Check the publish workflow here: https://github.com/microsoft/playwright/actions/workflows/publish_release.yml. The step that builds and publishes the driver contains the exact version you need.
Now, with the driver version known, always start with running the roll script to update the version and regenerate the API to see the state of things.
./build.sh --roll <driver-version>Afterwards, walk through the upstream changes that affect the Java client and port the relevant ones.
List the upstream commits that touched a client-relevant path since the last roll. The paths cover everything that can change the public Java surface or the wire protocol:
docs/src/api/ — the source of truth for api.json. Method/option additions, removals, and langs: filter changes flow from here.packages/playwright-core/src/client/ — the JS client implementation that the Java client mirrors.packages/isomorphic/ — selector engines, locator generation/parsing, and aria-snapshot logic shared between client and server. Changes here can affect client-side helpers like getByRoleSelector.packages/playwright/src/matchers/matchers.ts — assertion-method definitions. Changes here usually correspond to new options on LocatorAssertions / PageAssertions.packages/protocol/spec/**.yml — the wire protocol schema. Method/event additions, parameter renames, and result-shape changes affect what the .NET implementation classes need to send/receive.cd ~/playwright

This file becomes the body of the eventual PR.The .NET client is a port of the JS client in ../playwright/packages/playwright-core/src/client/. When implementing a new or changed method, always read the corresponding JS file first and mirror its logic:
../playwright/packages/playwright-core/src/client/browserContext.ts
../playwright/packages/playwright-core/src/client/page.ts
...Read the final state at the release tag, not just the introducing PR diff. When a feature evolves across multiple PRs (e.g. a method was introduced in one PR, then some options were added in follow-ups, then some logic was changed), the original PR's diff is a misleading reference — the final shape lives in git show v1.X.0:packages/playwright-core/src/client/foo.ts. Always read the v1.X.0 file before porting non-trivial logic.
Key translation rules:
Protocol calls — await this._channel.methodName(params) → SendMessageToServerAsync("methodName", paramsDictionary)
Extracting a returned channel object from a result — JS uses SomeClass.from(result.foo) which resolves the JS-side object for a channel reference. In .NET, extract it from the connection: .GetObject<Foo>("foo", _connection)
Watch for channel migrations. A method that lived on BrowserContext may move to Tracing (and vice-versa) without notice — the protocol spec is the source of truth. If a SendMessageToServerAsync("foo", ...) call suddenly fails, grep packages/protocol/spec/*.yml to find which channel actually owns foo now.
Wire format changes can be subtle. A method's result shape can change without renaming anything. These are easy to miss when walking client.ts because the JS code just adapts; the regression only surfaces when an existing test's deserialization breaks. Always diff packages/protocol/spec/*.yml for each commit on the walk list, not just the client code.
Update tests similarly to upstream. When upstream removes or modifies a test, apply similar changes.
When the API generator produces an unhelpful name for a return type (e.g. Bind instead of BrowserBindResult), you can control it by adding a struct alias in the upstream docs.
In the docs markdown file (e.g. docs/src/api/class-browser.md), add alias (applies to all languages) or alias-csharp (overrides for .NET only) to the <[Object]> type:
-- returns: <[Object]>
+- returns: <[Object]>
+ - alias-csharp: BrowserBindResultUse alias-csharp (in addition to bare alias) when upstream already declared a different alias for other languages and you only want to override .NET's name — typically to preserve a name we've already shipped and don't want to break. After making this change, re-run ./build.sh --roll <version> to regenerate, then update any hand-written implementation code to use the new type name. The upstream docs change must also land in microsoft/playwright via a separate PR or it will revert on the next roll.
After porting, run the chromium suite end-to-end before opening the PR — many regressions only surface in older tests that depended on now-changed behavior. Tests take ~8–10 minutes:
BROWSER=chromium dotnet test ./src/Playwright.Tests/Playwright.Tests.csproj \
-c Debug -f net8.0 --logger:"console;verbosity=detailed" > /tmp/test-results.txt 2>&1
grep "^ Failed " /tmp/test-results.txt # list failures
tail -5 /tmp/test-results.txt # summaryRun as a background task — don't block the conversation on it. For each failure: check whether it's a flake (port collision, browser timing) by running the single test in isolation, then investigate whether your roll introduced it or it's pre-existing.
