Specific hang issues were fixed by the terminal owner (milestones Feb/Jul 2025) without public root cause. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/microsoft/vscode-docs/main/docs/terminal/shell-integration.md (official_docs, unknown, documented_behavior): Docs define None/Basic/Rich quality, list cases where automatic injection fails (PROMPT_COMMAND format, plugins unsetting VSCODE_SHELL_INTEGRATION, sub-shells, ssh) and manual install. - https://github.com/microsoft/vscode-copilot-release/issues/4814 (github_issue, 2025-02-09, reported_symptom): VS Code 1.98 insider / Copilot Chat 0.25: agent mode hangs at 'Running command in terminal…'; labeled verified bug, Feb 2025 milestone, closed. - https://github.com/microsoft/vscode/issues/254447 (github_issue, 2025-04-02, reported_symptom): VS Code 1.99 insider Windows: agent hangs with spinner after terminal command; verified bug, July 2025 milestone, closed.
