Web QA via the hai-agents CLI

When the user asks you to QA a web UI / review a deployed page / check a URL for issues:

1. Pick the right subcommand

• `qa-cli review` — full agent loop (~30–90s). Returns a structured ReviewResult JSON with verdict, summary, findings (each with severity, area, issue, suggestion), and steps_taken. Use this for any real review.
• `qa-cli visual` — one-shot visual question, returns a short free-text answer. Use for quick "what color is X" / "does the layout look broken" sanity checks.

2. Invoke

uv run qa-cli review --url <url> --instruction "<what to focus on>"
uv run qa-cli visual --url <url> --question "<single question>"

The CLI logs progress to stderr; the result (JSON for review, text for visual) goes to stdout. Pipe to jq if you want to filter.

3. Surface the result

For review:

• Lead with the verdict and the headline summary.
• List findings ordered as returned (already high-severity-first). Show each as [severity] area — issue and include the suggestion when actionable.
• If verdict == "fail", make it clear what blocked completion.

For visual: just relay the answer.

Notes

• Prerequisite: the qa-cli command comes from the `agents-api-demos` repo. If uv run qa-cli ... errors with "command not found", that repo isn't installed in the current working directory — tell the user to clone it and run uv sync before retrying, or fall back to whichever QA tool is already on PATH.
• Requires HAI_API_KEY in .env. On a missing key the CLI exits with error: HAI_API_KEY is not set... — relay that to the user verbatim; don't retry.
• review is expensive (one cloud session per call). Don't run multiple reviews in parallel for the same task — call it once with a focused --instruction.

Examples

User: "Please QA https://news.ycombinator.com for accessibility."

You: Run uv run qa-cli review --url https://news.ycombinator.com --instruction "focus on accessibility — alt text, form labels, keyboard nav, contrast". Parse JSON. Surface findings.

User: "What color is the main CTA on https://example.com?"

You: Run uv run qa-cli visual --url https://example.com --question "what color is the main call-to-action button?". Return the answer.
