Pull request overview

This PR updates the VSC Model A prompt to a new "0129" version by replacing the entire system prompt content while maintaining the same structure. The changes represent a significant shift in prompting strategy, removing planning/todo list instructions and response translation rules, while adding new guidance around parallel tool usage, response formatting requirements, and assistant message ordering.

Changes:

• Replaced planning/todo list instructions with parallel tool use guidance emphasizing multi_tool_use for efficiency
• Added explicit final_first_requirement and commentary_first_requirement tags to control assistant message ordering
• Created new VSCModelReminderInstructionsA class with additional constraints referencing the new requirements
• Removed imports for ResponseTranslationRules, McpToolInstructions, and NotebookInstructions that are no longer used

• The response text "sure I am here to help." should be "Sure, I am here to help." with a capital "S" at the beginning and a comma after "Sure" for proper grammar. Additionally, there's a double period ".." which should be a single period.

				if the request is ambiguous, respond with "sure I am here to help.".<br />

src/extension/prompts/node/agent/vscModelPrompts.tsx:116

• There are two consecutive blank lines (115-116) before the closing tag. This appears to be unnecessary whitespace. Consider removing one blank line for consistency with the rest of the codebase.

• There's a grammatical error with a duplicated word "If". The sentence reads "You are encouraged to call functions in parallel if If you think..." - the second "If" should be removed or the sentence should be restructured.

				You are encouraged to call functions in parallel if If you think running multiple tools can answer the user's question to maximize efficiency by parallelizing independent operations. This reduces latency and provides faster responses to users.<br />

Grammatical error: "User say hello" should be "User says hello" to maintain subject-verb agreement.

This issue also appears in the following locations of the same file:

	If the answer is direct and needs no tools or multi-step work (e.g. User say hello), respond with ONE final message only. No commentary or analysis messages are needed. That is, you should only send one message, the final answer.<br />
	You CANNOT call commentary and then final right after that.<br />
	</Tag>
	<Tag name='commentary_first_requirement'>
	If not satisfying the final_first_requirement, you should ALWAYS obey this requirement: before starting any analysis or tool call, send an initial commentary-channel message that is at most two sentences (prefer one).<br />
	It must restate the user's clear request while acknowledging you will handle it.<br />
	if the request is ambiguous, respond with "sure I am here to help.".<br />

Inconsistent formatting with VSCModelPromptB. In line 59, the heading is just "❌ BAD" without additional context, while VSCModelPromptB at line 165 has "❌ BAD - Exceeding parallel limits:" which is more descriptive. Consider adding a descriptive label after "BAD" for consistency and clarity.

Suggested change

	❌ BAD<br />
	❌ BAD - Exceeding parallel limits:<br />
