Fixes:
- Bug: page.screenshotWithAccessibilityLabels was called as method on page,
fixed to standalone function call
- Removed duplicate 'debugging playwriter issues' section at end of file
(identical to the detailed one earlier)
- Softened waitForTimeout rule: short waits (1-2s) now acknowledged as
acceptable for non-deterministic events like popups/animations
- Fixed download example path from /tmp/ to ./
- Added note that bare 'page' in examples is for brevity, real automation
should use state.myPage
- Consolidated diff behavior explanation to one place in snapshot section
(was repeated 3 times with slight inconsistencies)
- Trimmed redundant 'prefer snapshots' advice to reference the dedicated
'choosing between snapshot methods' section
- Consolidated cmd+click popup advice (was in both mistakes and common
patterns with duplicate examples)
- Cross-referenced iframe approaches: frameLocator for locator chaining,
contentFrame for Frame objects needed by snapshot()
- Clarified require is the only option in sandbox (ESM import unavailable)
The observe step now has an inner loop — if the page isn't ready (still
loading, wrong URL, expected content missing), the agent loops back to
observe again instead of acting on stale state. The ASCII diagram shows
the 'not ready' branch looping back to observe.
Every observe step in the example now prints page.url() before the
snapshot so the agent always knows the current URL. This catches
redirects and unexpected navigation between actions.
Add a 'computer use' section to skill.md showing how Playwriter covers all
actions from the Anthropic computer_20250124 tool and the Claude Chrome
extension's custom computer tool, using Playwright APIs instead of
screenshot-based coordinate clicking.
Each subsection shows the declarative locator-based approach first (preferred)
with coordinate-based fallback for canvas/maps/custom widgets.
Also adds docs/claude-extension-tools.json with all 16 tool schemas extracted
from the Claude Chrome extension v1.0.39 (minified source) for reference.
Add observe → act → observe feedback loop section with ASCII diagram
and Framer command palette example. Agents must take a snapshot after
every action to verify the result before proceeding.
Also change page creation pattern to reuse existing about:blank tabs
instead of always creating new ones, with a note to navigate immediately
in the same execute call to prevent concurrent agents from grabbing the
same tab.
When the Playwriter extension can't connect because Chrome isn't running,
agents now have platform-specific commands (macOS, Linux, Windows) to start
Chrome from the CLI. Also documents the --allowlisted-extension-id and
--auto-accept-this-tab-capture flags for enabling automatic tab capture
for screen recording without manual extension clicks.
