Media Search & Play

Resolve "play X" / "listen to X" / "find me a song" requests by chaining web_search (optional, for fuzzy intent) → youtube_search (REQUIRED, returns real watch URLs) → browser_navigate (REQUIRED, must use a URL that came back from youtube_search). Keep navigation, interaction and Evidence inside the owned Browser Session. Navigation alone does not prove playback.

<execute_action> The user's request authorizes the requested media action, subject to the runtime's approval and browser policy. Use the actual available controlled browser tools. External open_url launching is unavailable inside durable Jobs and is not a recovery path.

After navigation, inspect the player. If playback has not started, use the observed play control through an admitted browser action. Verify observable player state (for example paused=false and advancing currentTime, when supported) before claiming playback. A screenshot or loaded watch URL alone does not establish that audio is playing.

Do not bypass approval, login, CAPTCHA, browser policy, or autoplay restrictions. If a supported action or verification is unavailable, report that exact limitation. Never claim success from an attempted action. </execute_action>

<selection_rule> How strict you should be about picking a candidate from youtube_search depends on how specific the user's query is.

VAGUE query, no specific song or artist named. Examples: "play me a popular song", "play me a hindi song", "play something upbeat", "put on some jazz", "play a sad song".

→ Walk the youtube_search candidates top-down and pick the first one whose title does NOT match any of the anti-patterns below. That is the answer. Do not score candidates further; do not look for "the most official one"; do not compare view counts. The first non-anti-pattern wins.

Anti-pattern keywords (match case-insensitively against title):
