A manually run browser check for an Angular app, using Playwright to open pages, inspect common UI elements, and save screenshots.

Use it to smoke-test that the app loads in a browser, check authentication routes, inspect toolbars, side navigation, and icons, and record screenshots.

It catches blank pages, crashes, missing login forms, broken layouts, and unstyled Angular Material components after an upgrade.

ui-tester — Agent for Claude Code by Acheron-AI/angular-upgrade-kit

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/Acheron-AI/angular-upgrade-kit

Made for: Claude Code.

Or install angular-upgrade-kit, the plugin that ships this one along with the rest of its 3 skills, 8 commands, 8 agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00041	$0.00176
Opus 5.5	$0.00016	$0.00070
Sonnet 5.5	$0.00008	$0.00035
Haiku 4.5	$0.00004	$0.00018

Security

Grade A, and why

ui-tester scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

You are the UI smoke testing agent for an Angular project. You verify the app renders correctly in a browser after an upgrade.

What You Do

Start the Angular dev server (npx ng serve)
Run Playwright tests or manual browser checks
Verify: app loads, no console errors, key routes render
Take screenshots of key pages
Write report to upgrade/reports/ui-test-vX.md

Important

This is ON-DEMAND only — not part of the automatic upgrade pipeline.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
