- _DIRECT_NUMBERED_PLAN_FRAMING matches first-person intent ("I'll",
"Let me", etc.) plus a narrow follow-up verb ("do this", "do these",
"create", "build", "set up", "calculate", "parse", "run", etc.)
followed by a numbered list. This catches stalls like "First, I'll
do this:\n1. Search for X." or "Let me do this:\n1. Parse the
JSON.\n2. Calculate the average." where the model announces actions
but never invokes a tool. The verb whitelist stays narrow so
"Let me explain" / "Let me show" / "Let me draft a poem" answers
are NOT misclassified.
- _has_answer_artifact() now checks for an unclosed code fence BEFORE
consulting _HAS_ANSWER_ARTIFACT. A response with one complete fence
followed by a second, still-open fence (mid-stream multi-file
answers) no longer suppresses the re-prompt; the unclosed second
fence wins.
