name	Validate agent-browser for Web Automation
description	Test agent-browser (Playwright-based) on host with unrestricted network and Playwright browsers installed. **Validation steps**: - Install browsers: `npx playwright install` - Test: `npx agent-browser open https://code.claude.com/docs/en/skills` - Test: `npx agent-browser snapshot -i` (get element refs) - Test: `npx agent-browser get text body` (extract page text) - Verify snapshot/interact/re-snapshot workflow works - Document prerequisites for skill to function **Blocked on 2026-02-05**: Could not download Playwright browsers (DNS resolution failed, missing system libs) **Skill location**: `.claude/skills/agent-browser/SKILL.md`

Fact-Check

Claims checked: 5 VERIFIED: 4 | REFUTED: 1 | INCONCLUSIVE: 0

1. agent-browser is a real npm package — VERIFIED (v0.15.0, Vercel Labs, playwright-core dependency)
2. npx agent-browser open <url> works — VERIFIED (confirmed via --help)
3. npx agent-browser snapshot -i gets element refs — VERIFIED (documented with -i, --interactive flag)
4. npx agent-browser get text body extracts page text — REFUTED — documented syntax is get text <selector> where selector is @e1 ref or CSS selector. body works as CSS selector but is not the documented pattern.
5. snapshot/interact/re-snapshot workflow — VERIFIED (core workflow in SKILL.md and --help examples)

Refuted claims: get text body syntax — misleading but functional (body is a CSS selector) Citations: npm registry (v0.15.0), npx agent-browser --help output, GitHub repository docs (accessed 2026-02-26)

RT-ICA

Goal: Verify agent-browser skill works end-to-end on a properly equipped host and document prerequisites.

#	Condition	Status	Evidence
1	agent-browser CLI available	AVAILABLE	v0.15.0 via npx
2	Playwright browsers installed	AVAILABLE	Chromium 141.0 at /root/.cache/ms-playwright/
3	Network access for test URLs	DERIVABLE	Environment has network; target URL accessibility unverified
4	Skill documentation exists	AVAILABLE	SKILL.md + 7 references + 3 templates
5	Validation step syntax correct	MISSING	get text body refuted — should use get text <selector> with @ref or CSS
6	System libs for rendering	DERIVABLE	Headless mode should work; headed may need X11

Decision: APPROVED — no blockers for headless validation Missing: Update validation step to use get text @e1 or get text body (as CSS selector) with clarifying note

Reproducibility

1. Install agent-browser: npm install -g agent-browser (or use npx)
2. Install Playwright browsers: agent-browser install (or npx playwright install chromium)
3. Open a test URL: agent-browser open https://example.com
4. Take interactive snapshot: agent-browser snapshot -i
5. Extract text via element ref: agent-browser get text @e1 (ref from snapshot output)
6. Chain open + wait + snapshot: agent-browser open https://example.com && agent-browser wait --load networkidle && agent-browser snapshot -i
7. Close browser: agent-browser close

Dependencies

• Node.js 18+ with npx
