[WIP] Add new chat tip for Copilot CLI agent

[Copilot]

Cloud agent has begun work on Start implementation and will update this pull request as work progresses.

Original prompt

Start implementation

The user has attached the following file paths as relevant context:

• .github\copilot-instructions.md
• .github\copilot-instructions.md
• .claude\CLAUDE.md
• AGENTS.md

[Chronological Review: The conversation began with the user requesting to add a new chat tip related to the Copilot CLI agent. The user specified the content of the tip and the functionality of switching sessions to Copilot CLI. The user then requested to start the implementation of this feature.]

[Intent Mapping:

• User Request 1: "I want to add a new chat tip related to the Copilot CLI agent. It should say something like 'Run agents in parallel using Copilot CLI.' Clicking Copilot CLI should be a command that switches the sessions target to Copilot CLI."
• User Request 2: "Start implementation."]

[Technical Inventory:

• Repository: vscode-copilot-chat
• Current Branch: pierceboggan/model-picker-vendor-ordering
• Default Branch: main
• Active Pull Request: Experiment: sort model picker by vendor (OpenAI, Anthropic, Gemini) - https://github.com/microsoft/vscode-copilot-chat/pull/4965]

[Code Archaeology:

• Current File: c:\Users\cowebster\Documents\vscode\src\vs\workbench\contrib\chat\test\browser\agentSessions\agentSessionsAccessibilityProvider.test.ts
• No specific code changes or functions were discussed yet, as the user was in the initial stages of implementation.]

[Progress Assessment:

• Completed Tasks: User has defined the new chat tip and its functionality.
• Partially Complete Work: Implementation of the chat tip is pending.]

[Context Validation: All necessary context for continuing the implementation of the chat tip is captured, including the specific wording and functionality required.]

[Recent Commands Analysis:

• Last Agent Commands: User requested to start the implementation of the chat tip.
• Tool Results Summary: No tool results were generated as the user was in the process of defining the feature.
• Pre-Summary State: The agent was actively working on the implementation of the chat tip when the token budget was exceeded.
• Operation Context: The commands executed were directly related to the user's goal of enhancing the Copilot CLI functionality within the chat interface.]

1. Conversation Overview: - Primary Objectives: User requested to add a chat tip: "Run agents in parallel using Copilot CLI." The tip should allow switching sessions to Copilot CLI. - Session Context: The conversation focused on defining and starting the implementation of a new chat tip related to the Copilot CLI agent. - User Intent Evolution: The user moved from defining the feature to initiating its implementation.

2. Technical Foundation:

• Repository: vscode-copilot-chat
• Current Branch: pierceboggan/model-picker-vendor-ordering
• Default Branch: main
• Active Pull Request: Experiment: sort model picker by vendor (OpenAI, Anthropic, Gemini)

• Lessons Learned: Not applicable yet.

5. Progress Tracking:

• Completed Tasks: User has defined the new chat tip and its functionality.
• Partially Complete Work: Implementation of the chat tip is pending.
• Validated Outcomes: None yet as the implementation has not begun.

6. Active Work State:

• Current Focus: User is focused on implementing the new chat tip for the Copilot CLI.
• Recent Context: The user requested to start the implementation after defining the chat tip.
• Working Code: No specific code snippets have been modified or discussed yet.
• Immediate Context: The user was preparing to implement the chat tip when the token budget was exceeded.

7. Recent Operations:

• Last Agent Commands: User requested to start the implementation of the chat tip.
• Tool Results Summary: No tool results were generated as the user was defining the feature.
• Pre-Summary State: The agent was actively working on the implementation of the chat tip.
• Operation Context: The commands executed were directly related to the user's goal of enhancing the Copilot CLI functionality.

8. Continuation Plan:

• Pending Task 1: Implement the chat tip with the specified functionality.
• Pending Task 2: Ensure that clicking the Copilot CLI switches the session target.
• Priority Information: The implementation of the chat tip is the most urgent task.
• Next Action: Begin coding the implementation of the chat tip as defined by the user.
