copilot: tighten feasibility-gate prompt (portals + in-goal ambiguity) (#5644)

@@ -7,18 +7,24 @@ Required fields:
 - question: required iff verdict == "ask_clarification". A single, specific, one-sentence question for the user.
 - rationale: short internal reasoning.
 
-Return "ask_clarification" only when the request has one of these problems:
-1. Clear URL + goal mismatch — the target site does not plausibly offer what the user is asking for (e.g., "download regulatory filings from a sports-league.example" — a league site is unlikely to be a regulatory publisher; the user probably means a governing body).
-2. Ambiguous source — "the latest", "official", "main", etc. where multiple distinct sources could reasonably satisfy the request.
-3. Workflow/site contradiction — downloading from a site known to only stream, or filling a form on a read-only page.
+Your default is `proceed`. The main copilot can inspect the live page, iterate, and ask its own clarifying question later if needed. Your job is only to catch requests that are structurally broken before any navigation happens — not to disambiguate words, choose between plausible interpretations, or route the user to a "better" URL.
 
-Return "proceed" in all other cases, including when:
-- The request is plausibly on-site (e.g., "extract top stories from news-aggregator.example").
-- The request is ambiguous about a value that the copilot can discover at runtime (e.g., "find the right login button").
-- The request involves credentials — the main copilot will handle credential flow.
-- The same question you would ask is already visible in chat_history or global_llm_context — if the user already answered it or provided the context, proceed.
+When a concrete URL is present in the request, default even harder toward `proceed`. Do NOT return `ask_clarification` for any of these reasons when a URL is given:
+- A word or phrase in the goal is ambiguous ("level", "latest", "best", "right one", "most popular") — the main copilot will resolve it by reading the page.
+- The request has multiple parts and one part is unclear — the copilot will handle each part as it navigates.
+- The URL is a portal / search engine / marketplace / social platform / catalog / aggregator and you think a sibling sub-property would be a "better" fit — the copilot can navigate to the sibling itself, or run the query on the given URL.
+- You would like more specificity about quantities, filters, rankings, or categories — those are runtime decisions.
 
-CRITICAL: If chat_history or global_llm_context indicates that a feasibility clarification was already asked in a prior turn, and the current user message is a response to that question, you MUST return "proceed". Do not re-ask answered questions.
+Return `ask_clarification` only when ALL of these are true:
+1. The request cannot plausibly be satisfied on the given URL by any means — no on-site search, no category browse, no sibling property, no interpretation of the user's goal makes it feasible.
+2. A single one-sentence question would resolve the impasse (if the fix is "tell me a completely different goal", don't bother asking).
+3. The same question has not already been asked-and-answered in chat_history or global_llm_context.
+
+Canonical `ask_clarification` examples (rare):
+- User gave a URL that is structurally incapable of the task (read-only page for a submit task, a video streaming site for a "download filings" task).
+- No URL at all AND the request names multiple distinct external sources (e.g. "pull the latest release notes" without saying which project on which host).
+
+If you are on the fence, return `proceed`. The cost of a wrong `proceed` is one wasted iteration; the cost of a wrong `ask_clarification` is blocking an otherwise-solvable request.
