All `-e` arguments in bash examples now use single quotes instead of double
quotes. This prevents bash from interpreting `$`, backticks, and backslashes
inside JS code — a major pain point for agents that construct playwriter
commands programmatically.
Changes across skill docs, README, and website copies:
- **Single quotes for one-liners**: `playwriter -s 1 -e 'await page.goto("...")'`
- **Heredoc preferred for multiline**: `<<'EOF'` disables all bash expansion
- **Quoting rules summary**: explains when to use single quotes vs heredoc vs `$'...'`
- **Rewrote mistake #6**: now explains *why* double quotes break (bash `$` expansion
silently corrupts regex like `/\$[\d.]+/` and template literals)
- **Added locator-scoped snapshot section**: shows `snapshot({ locator: page.locator("main") })`
which dramatically reduces output size from ~150 lines to ~20 lines by snapshotting
only a subtree instead of the full page
- **Added single-quote tip** to README quick start and SKILL.md stub
The locator-scoped snapshot feature already existed but wasn't documented.
Discovered during real-world Cloudflare dashboard automation where full page
snapshots were dominated by 60+ sidebar navigation links.
Add explicit guidance to use playwriter first for JS-rendered websites and blocking overlays, based on repeated failures where webfetch/curl returned empty shells and screenshots were used too early.
Key updates:\n- Add a hard 'when to use playwriter vs webfetch/curl' rule in the main skill docs\n- Add a 'snapshot before screenshot' rule to prevent slow image-first debugging loops\n- Add a concrete anti-pattern for JS-rendered sites in common mistakes\n- Add obstacle-handling flow for cookie/login/age-gate overlays\n- Add media extraction/download pattern using evaluate + Node fetch/fs\n- Update skill frontmatter description (and well-known discovery copies) so context-loaded summaries also include the JS-heavy-site rule
