Empty Terminal Capturing When Using Copilot Chat Agent

• Copilot Chat Extension Version: 1.16.0
• VS Code Version: 1.116.0
• OS Version: Darwin arm64 25.3.0
• Feature (e.g. agent/edit/ask mode): agent
• Selected model (e.g. GPT 4.1, Claude 3.7 Sonnet): auto (GPT-5.3-Codex • 0.9x)
• Logs:

I’ll pull the latest `main`, merge it into your current branch `docs/update-highlighter-componentsource`, resolve any conflicts, and verify the workspace is in a clean, PR-ready state. I’m starting by checking git status/branch and syncing refs so we can integrate safely.I’m loading the pull request workflow skill now so I can follow the repository’s expected PR process while integrating `main` into your branch.

Read memory

Next I’m going to inspect your git state and fetch the latest `main` from origin so we can merge exactly what changed and avoid surprises.

Ran terminal command:  git status --short --branch && git branch -vv

Ran terminal command:  git fetch origin

I fetched remote refs successfully; now I’ll run explicit git checks with machine-readable output to confirm branch divergence and whether there are local uncommitted changes before merging.

Ran terminal command:  pwd && git rev-parse --abbrev-ref HEAD && git status --porcelain=v1 && git status -sb && git rev-list --left-right --count origin/main...HEAD

I’m seeing unusually empty terminal captures, so I’m running a minimal command to verify terminal output behavior before continuing with git operations.

Ran terminal command:  echo HI && /bin/pwd && git rev-parse --abbrev-ref HEAD

Terminal output still looks suppressed in this environment; I’ll switch to a persistent async terminal and read back its output directly to proceed safely.

Ran terminal command:  echo HI && pwd && git rev-parse --abbrev-ref HEAD && git status -sb

I confirmed we’re on the correct branch; next I’ll check divergence against `origin/main` and whether any local changes need to be stashed before merge.

Sent `git fetch origin && echo 'DIVERGENCE (behind ahead):' && git rev-list --left-...` to terminal

Steps to Reproduce:

1. Open a repository with a branch that is behind origin/main
2. Open Copilot Chat and use Agent mode
3. Run a prompt like:
   "Now the main branch has a new commit and can you help me integrate to current branch? docs/update-highlighter-componentsource that I want to make a PR"
4. Observe the agent executing git commands (e.g., git merge origin/main)
5. Check the terminal panel output

Expected Behavior:

• Terminal should reliably display all executed commands and their outputs
• Output should persist for review (e.g., merge logs, git status, push results)

Actual Behavior:

• Terminal output is intermittently empty or not captured
• Some commands appear to execute (based on agent responses), but no corresponding terminal logs are visible
• Makes it difficult to verify actions like merges, pushes, or PR creation

Additional Context:

• The agent successfully performed:
  • git merge origin/main
  • git push
  • PR creation via GitHub
• However, terminal output was missing or incomplete during parts of the process
• This creates a lack of transparency and makes debugging harder

Reproducibility:

• Always fail when fetching information from Terminal with copilot.
