Proceed." --append-system-prompt "You are an AI issue solver. You prefer to find the root cause of each and every issue. When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements.

General guidelines.
   - When you execute commands, always save their logs to files for easier reading if the output becomes large.
   - When running commands, do not set a timeout yourself — let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file.
   - When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command.
   - When CI is failing or user reports failures, consider adding a detailed investigation protocol to your todo list with these steps:
      Step 1: List recent runs with timestamps using: gh run list --repo link-foundation/start --branch issue-15-d3d0f1c82afa --limit 5 --json databaseId,conclusion,createdAt,headSha
      Step 2: Verify runs are after the latest commit by checking timestamps and SHA
      Step 3: For each non-passing run, download logs to preserve them: gh run view {run-id} --repo link-foundation/start --log > ci-logs/{workflow}-{run-id}.log
      Step 4: Read each downloaded log file using Read tool to understand the actual failures
      Step 5: Report findings with specific errors and line numbers from logs
      This detailed investigation is especially helpful when user mentions CI failures, asks to investigate logs, you see non-passing status, or when finalizing a PR.
      Note: If user says \"failing\" but tools show \"passing\", this might indicate stale data - consider downloading fresh logs and checking timestamps to resolve the discrepancy.
   - When a code or log file has more than 1500 lines, read it in chunks of 1500 lines.
   - When facing a complex problem, do as much tracing as possible and turn on all verbose modes.
   - When you create debug, test, or example/experiment scripts for fixing, always keep them in an examples and/or experiments folders so you can reuse them later.
   - When testing your assumptions, use the experiment scripts, and add it to experiments folder.
   - When your experiments can show real world use case of the software, add it to examples folder.
   - When you face something extremely hard, use divide and conquer — it always helps.

Initial research.
   - When you start, make sure you create detailed plan for yourself and follow your todo list step by step, make sure that as many points from these guidelines are added to your todo list to keep track of everything that can help you solve the issue with highest possible quality.
   - When user mentions CI failures or asks to investigate logs, consider adding these todos to track the investigation: (1) List recent CI runs with timestamps, (2) Download logs from failed runs to ci-logs/ directory, (3) Analyze error messages and identify root cause, (4) Implement fix, (5) Verify fix resolves the specific errors found in logs.
   - When you read issue, read all details and comments thoroughly.
   - When you see screenshots or images in issue descriptions, pull request descriptions, comments, or discussions, use WebFetch tool (or fetch tool) to download the image first, then use Read tool to view and analyze it.
   - When you need issue details, use gh issue view https://github.com/link-foundation/start/issues/15.
   - When you need related code, use gh search code --owner link-foundation [keywords].
   - When you need repo context, read files in your working directory.
   - When you study related work, study the most recent related pull requests.
   - When issue is not defined enough, write a comment to ask clarifying questions.
   - When accessing GitHub Gists (especially private ones), use gh gist view command instead of direct URL fetching to ensure proper authentication.
   - When you are fixing a bug, please make sure you first find the actual root cause, do as many experiments as needed.
   - When you are fixing a bug and code does not have enough tracing/logs, add them and make sure they stay in the code, but are switched off by default.
   - When you need latest comments on pull request (sorted newest first), use appropriate GitHub API commands.
   - When you need latest comments on issue (sorted newest first), use appropriate GitHub API commands.

Solution development and testing.
   - When issue is solvable, implement code with tests.
   - When coding, each atomic step that can be useful by itself should be commited to the pull request's branch, meaning if work will be interrupted by any reason parts of solution will still be kept intact and safe in pull request.
   - When you test:
      start from testing of small functions using separate scripts;
      write unit tests with mocks for easy and quick start.
   - When you test integrations, use existing framework.
   - When you test solution draft, include automated checks in pr.
   - When issue is unclear, write comment on issue asking questions.
   - When you encounter any problems that you unable to solve yourself (any human feedback or help), write a comment to the pull request asking for help.
   - When you need human help, use gh pr comment 16 --body \"your message\" to comment on existing PR.

Preparing pull request.
   - When you code, follow contributing guidelines.
   - When you commit, write clear message.
   - When you need examples of style, use gh pr list --repo link-foundation/start --state merged --search [keywords].
   - When you open pr, describe solution draft and include tests.
   - When there is a package with version and GitHub Actions workflows for automatic release, update the version (or other necessary release trigger) in your pull request to prepare for next release.
   - When you update existing pr 16, use gh pr edit to modify title and description.
   - When you are about to commit or push code, ALWAYS run local CI checks first if they are available in contributing guidelines (like ruff check, mypy, eslint, etc.) to catch errors before pushing.
   - When you finalize the pull request:
      follow style from merged prs for code, title, and description,
      make sure no uncommitted changes corresponding to the original requirements are left behind,
      make sure the default branch is merged to the pull request's branch,
      make sure all CI checks passing if they exist before you finish,
      double-check that all changes in the pull request answer to original requirements of the issue,
      make sure no new new bugs are introduced in pull request by carefully reading gh pr diff,
      make sure no previously existing features were removed without an explicit request from users via the issue description, issue comments, and/or pull request comments.
   - When you finish implementation, use gh pr ready 16.

Workflow and collaboration.
   - When you check branch, verify with git branch --show-current.
   - When you push, push only to branch issue-15-d3d0f1c82afa.
   - When you finish, create a pull request from branch issue-15-d3d0f1c82afa. (Note: PR 16 already exists, update it instead)
   - When you organize workflow, use pull requests instead of direct merges to default branch (main or master).
   - When you manage commits, preserve commit history for later analysis.
   - When you contribute, keep repository history forward-moving with regular commits, pushes, and reverts if needed.
   - When you face conflict that you cannot resolve yourself, ask for help.
   - When you collaborate, respect branch protections by working only on issue-15-d3d0f1c82afa.
   - When you mention result, include pull request url or comment url.
   - When you need to create pr, remember pr 16 already exists for this branch.

Self review.
   - When you check your solution draft, run all tests locally.
   - When you compare with repo style, use gh pr diff [number].
   - When you finalize, confirm code, tests, and description are consistent." | jq -c .)

Use `script /dev/null` to spawn a PTY\nLogin directly to \"user_name\" via ssh. Take ownership of the shell by typing `script /dev/null` as the user and then type screen.(no content)\"Inside the docker container, run `script /dev/null` first.

Use `script /dev/null` to spawn a PTY\nLogin directly to \"user_name\" via ssh. Take ownership of the shell by typing `script /dev/null` as the user and then type screen.(no content)\"Inside the docker container, run `script /dev/null` first. Then you should be able to start screen\"\n\n### 2. Use Python's pty module\nYou can define a script as follows: `exec python -c 'import pty; pty.spawn(\"/bin/bash\")'` - Then you would get a proper PTY.(no content)To address this, you could consider utilizing the python module pty. In the case where you possess an interactive terminal, you may experiment with `script /dev/null`, followed by the screen.\n\n### 3.

You can spawn a pty process with `handleFlowControl: true` and use PAUSE (`\\x13`) and RESUME (`\\x11`) to block and resume the child program.\n\n## child_pty\n\nThe `child_pty` module is for creating and interacting with pseudo terminals. It tries to be as minimal as possible and borrows most of its functionality from child_process.(no content)The options.stdio allows 'pty' as an array element, and this value indicates that the fd is bound to the pty. The default stdio is `['pty', 'pty', 'pty']`.\n\n## stmux - Terminal Multiplexer for Node.js\n\nstmux is a simple terminal multiplexing utility for Node.js environments. It is inspired by tmux and is intended to provide a tiny subset of tmux functionality in a portable way for bare Node.js environments.(no content)Internally, stmux is based on the Blessed screen rendering environment and emulates full XTerm-compatible pseudo-terminals using Blessed XTerm, XTerm.js terminal rendering, and node-pty pseudo-terminal integration modules.\n\n## Issues with tmux/screen in node-pty\n\nThere's a known issue when running demanding programs like tmux with node-pty:\n\nSome users have reported trying to achieve something akin to what `script` does - using node-pty to spawn a PTY and read/save its output. The same approach in Python using the pty module works without problems.(no content)A suggested solution is to set the tty of the hosting process to raw mode (like Python's pty.spawn does), which skips all translations done by the tty/termios of the outer pty.(no content)The reason is that `setRawMode(true)` in Node.js calls `uv_tty_set_mode` passing `UV_TTY_MODE_RAW` which sets some termios flags manually, while `UV_TTY_MODE_IO` directly maps to `cfmakeraw`, which is not natively available via the Node.js API.\n\n## Code Examples\n\nTypical usage pattern for node-pty:\n```javascript\nconst ptyProcess = pty.spawn(shell, args, {\n    name: 'xterm-256color',\n    cols: 80,\n    rows: 30,\n    cwd: workingDirectory,\n    env: process.env\n});\n\nptyProcess.on('data', data => {\n    // Handle output\n});\n\nptyProcess.on('exit', code => {\n    // Handle exit\n});\n```\n\n\nREMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks."

When using `$ --isolated screen -- echo \"hello\"`, the expected output \"hello\" is not shown - instead, only `[screen is terminating]` appears.\n\n### Environment\n\n- **Platform:** macOS (reported), Linux (reproduced)\n- **Package:** [email protected]\n- **Screen version:** Tested with GNU Screen\n\n## Timeline of Events\n\n1. User installs start-command: `bun install -g start-command`\n2. Direct command execution works: `$ echo \"hello\"` shows \"hello\"\n3. Docker isolation works: `$ --isolated docker --image alpine -- echo \"hello\"` shows \"hello\"\n4. Screen isolation fails: `$ --isolated screen -- echo \"hello\"` shows only `[screen is terminating]`\n\n## Reproduction\n\n### Observed Behavior\n\n```\n$ echo \"hello\"\n[2025-12-22 13:45:05.245] Starting: echo hello\nhello\n[2025-12-22 13:45:05.254] Finished\nExit code: 0\n\n$ --isolated docker --image alpine -- echo \"hello\"\n[2025-12-22 13:45:07.847] Starting: echo hello\n[Isolation] Environment: docker, Mode: attached\n[Isolation] Image: alpine\nhello\nDocker container \"docker-...\" exited with code 0\n[2025-12-22 13:45:08.066] Finished\nExit code: 0\n\n$ --isolated screen -- echo \"hello\"\n[2025-12-22 13:45:11.134] Starting: echo hello\n[Isolation] Environment: screen, Mode: attached\n[screen is terminating]\nScreen session \"screen-...\" exited with code 0\n[2025-12-22 13:45:11.199] Finished\nExit code: 0\n```\n\n**Notice:** No \"hello\" output in the screen isolation case, though exit code is 0.\n\n## Root Cause Analysis\n\n### Investigation\n\n1. **TTY Requirement**: The GNU Screen command requires a connected terminal (TTY/PTY) to run in attached mode.\n\n2. **Node.js spawn behavior**: When spawning processes with `child_process.spawn()`, even with `stdio: 'inherit'`, Node.js does not always provide a proper pseudo-terminal (PTY) that screen requires.\n\n3. **Error in non-TTY environments**: Running `screen -S session shell -c command` without a TTY results in:\n   ```\n   Must be connected to a terminal.\n   ```\n\n4. **Detached mode works**: Running `screen -dmS session shell -c command` works because it doesn't require an attached terminal.\n\n### Experimental Evidence\n\nTesting revealed:\n- `process.stdin.isTTY` and `process.stdout.isTTY` are `undefined` when running from Node.js\n- Detached mode with logging (`screen -dmS ... -L -Logfile ...`) captures output correctly\n- Using `script -q -c \"screen ...\" /dev/null` can provide a PTY but includes terminal escape codes\n\n### Comparison with Docker\n\nDocker isolation works because:\n1. Docker run with `-it` flags handles terminal attachment\n2. Docker spawns an isolated container that manages its own pseudo-terminal\n3. The command output flows through Docker's I/O handling\n\n## Solution Options\n\n### Option 1: Use Script Command for PTY Allocation (Recommended)\n\nWrap the screen command with `script -q -c \"command\" /dev/null` to allocate a pseudo-terminal.\n\n**Pros:**\n- Provides a real PTY that screen requires\n- Works across Linux/macOS\n- Maintains attached behavior\n\n**Cons:**\n- Adds terminal escape codes to output\n- Requires `script` command to be available\n\n### Option 2: Switch to Detached Mode with Log Capture\n\nRun screen in detached mode (`-dmS`) with logging enabled (`-L -Logfile`), wait for completion,
[2025-12-22T13:53:42.900Z] [INFO]  then display the log.\n\n**Pros:**\n- Clean output without escape codes\n- Reliable across platforms\n- Captures full command output\n\n**Cons:**\n- Not truly \"attached\" - user can't interact with the process\n- Requires polling or waiting for completion\n\n### Option 3: Hybrid Approach (Chosen Solution)\n\nFor attached mode:\n1. Check if running in a TTY (`process.stdin.isTTY`)\n2. If TTY available: Use standard screen spawn with `stdio: 'inherit'`\n3. If no TTY: Use `script` command to allocate PTY\n\nFor detached mode:\n- Use existing implementation with `-dmS` flags\n\n## Implementation\n\nThe fix modifies `src/lib/isolation.js` to:\n\n1. Check for TTY availability before spawning screen\n2. Use `script` command as PTY allocator when no TTY is available\n3. Clean terminal escape codes from output when using script wrapper\n4. Maintain compatibility with existing detached mode\n\n## Testing Strategy\n\n1. **Unit tests**: Test TTY detection logic\n2. **Integration tests**: Test screen isolation in detached mode\n3. **Environment tests**: Test behavior with and without TTY\n\n## References\n\n- [GNU Screen Manual](https://www.gnu.org/software/screen/manual/screen.html)\n- [Stack Overflow: Must be connected to terminal](https://stackoverflow.com/questions/tagged/gnu-screen+tty)\n- [node-pty for PTY allocation](https://github.com/microsoft/node-pty)\n- [script command man page](https://man7.org/linux/man-pages/man1/script.1.html)\n\n## Appendix: Test Logs\n\nSee accompanying log files:\n- `test-output-1.log` - Initial reproduction\n- `screen-modes-test.log` - Screen modes investigation\n- `screen-attached-approaches.log` - Solution approaches testing\n"}}],"stop_reason":null,"stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":640,"cache_read_input_tokens":56294,"cache_creation":{"ephemeral_5m_input_tokens":640,"ephemeral_1h_input_tokens":0},"output_tokens":1564,"service_tier":"standard"},"context_management":null},"parent_tool_use_id":null,"session_id":"91b3b4eb-cc98-469e-9fd2-7dee25bdbcfb","uuid":"036134f4-1b5d-40a5-868a-df320dcaf972"}

When using `$ --isolated screen -- echo \"hello\"`, the expected output \"hello\" is not shown - instead, only `[screen is terminating]` appears.\n\n### Environment\n\n- **Platform:** macOS (reported), Linux (reproduced)\n- **Package:** [email protected]\n- **Screen version:** Tested with GNU Screen\n\n## Timeline of Events\n\n1. User installs start-command: `bun install -g start-command`\n2. Direct command execution works: `$ echo \"hello\"` shows \"hello\"\n3. Docker isolation works: `$ --isolated docker --image alpine -- echo \"hello\"` shows \"hello\"\n4. Screen isolation fails: `$ --isolated screen -- echo \"hello\"` shows only `[screen is terminating]`\n\n## Reproduction\n\n### Observed Behavior\n\n```\n$ echo \"hello\"\n[2025-12-22 13:45:05.245] Starting: echo hello\nhello\n[2025-12-22 13:45:05.254] Finished\nExit code: 0\n\n$ --isolated docker --image alpine -- echo \"hello\"\n[2025-12-22 13:45:07.847] Starting: echo hello\n[Isolation] Environment: docker, Mode: attached\n[Isolation] Image: alpine\nhello\nDocker container \"docker-...\" exited with code 0\n[2025-12-22 13:45:08.066] Finished\nExit code: 0\n\n$ --isolated screen -- echo \"hello\"\n[2025-12-22 13:45:11.134] Starting: echo hello\n[Isolation] Environment: screen, Mode: attached\n[screen is terminating]\nScreen session \"screen-...\" exited with code 0\n[2025-12-22 13:45:11.199] Finished\nExit code: 0\n```\n\n**Notice:** No \"hello\" output in the screen isolation case, though exit code is 0.\n\n## Root Cause Analysis\n\n### Investigation\n\n1. **TTY Requirement**: The GNU Screen command requires a connected terminal (TTY/PTY) to run in attached mode.\n\n2. **Node.js spawn behavior**: When spawning processes with `child_process.spawn()`, even with `stdio: 'inherit'`, Node.js does not always provide a proper pseudo-terminal (PTY) that screen requires.\n\n3. **Error in non-TTY environments**: Running `screen -S session shell -c command` without a TTY results in:\n   ```\n   Must be connected to a terminal.\n   ```\n\n4. **Detached mode works**: Running `screen -dmS session shell -c command` works because it doesn't require an attached terminal.\n\n### Experimental Evidence\n\nTesting revealed:\n- `process.stdin.isTTY` and `process.stdout.isTTY` are `undefined` when running from Node.js\n- Detached mode with logging (`screen -dmS ... -L -Logfile ...`) captures output correctly\n- Using `script -q -c \"screen ...\" /dev/null` can provide a PTY but includes terminal escape codes\n\n### Comparison with Docker\n\nDocker isolation works because:\n1. Docker run with `-it` flags handles terminal attachment\n2. Docker spawns an isolated container that manages its own pseudo-terminal\n3. The command output flows through Docker's I/O handling\n\n## Solution Options\n\n### Option 1: Use Script Command for PTY Allocation (Recommended)\n\nWrap the screen command with `script -q -c \"command\" /dev/null` to allocate a pseudo-terminal.\n\n**Pros:**\n- Provides a real PTY that screen requires\n- Works across Linux/macOS\n- Maintains attached behavior\n\n**Cons:**\n- Adds terminal escape codes to output\n- Requires `script` command to be available\n\n### Option 2: Switch to Detached Mode with Log Capture\n\nRun screen in detached mode (`-dmS`) with logging enabled (`-L -Logfile`), wait for completion, then display the log.\n\n**Pros:**\n- Clean output without escape codes\n- Reliable across platforms\n- Captures full command output\n\n**Cons:**\n- Not truly \"attached\" - user can't interact with the process\n- Requires polling or waiting for completion\n\n### Option 3: Hybrid Approach (Chosen Solution)\n\nFor attached mode:\n1. Check if running in a TTY (`process.stdin.isTTY`)\n2. If TTY available: Use standard screen spawn with `stdio: 'inherit'`\n3. If no TTY: Use `script` command to allocate PTY\n\nFor detached mode:\n- Use existing implementation with `-dmS` flags\n\n## Implementation\n\nThe fix modifies `src/lib/isolation.js` to:\n\n1. Check for TTY availability before spawning screen\n2. Use `script` command as PTY allocator when no TTY is available\n3. Clean terminal escape codes from output when using script wrapper\n4. Maintain compatibility with existing detached mode\n\n## Testing Strategy\n\n1. **Unit tests**: Test TTY detection logic\n2. **Integration tests**: Test screen isolation in detached mode\n3. **Environment tests**: Test behavior with and without TTY\n\n## References\n\n- [GNU Screen Manual](https://www.gnu.org/software/screen/manual/screen.html)\n- [Stack Overflow: Must be connected to terminal](https://stackoverflow.com/questions/tagged/gnu-screen+tty)\n- [node-pty for PTY allocation](https://github.com/microsoft/node-pty)\n- [script command man page](https://man7.org/linux/man-pages/man1/script.1.html)\n\n## Appendix: Test Logs\n\nSee accompanying log files:\n- `test-output-1.log` - Initial reproduction\n- `screen-modes-test.log` - Screen modes investigation\n- `screen-attached-approaches.log` - Solution approaches testing\n",

This PR implements a fix that:\n\n- Checks if a TTY is available before spawning screen\n- If no TTY is available, uses detached mode with log capture as a fallback\n- Polls for session completion and reads the captured log file\n- Displays the output to the user just as if it was running in attached mode\n\n## Root Cause Analysis\n\nGNU Screen requires a TTY (terminal) to run in attached mode. When spawning from Node.js without a terminal (such as in CI/CD pipelines, scripts, or piped output), screen fails with \"Must be connected to a terminal\" error. The previous code didn't handle this case properly.\n\n## Solution\n\nThe fix implements a hybrid approach:\n1. Check if running in a TTY using `process.stdin.isTTY`\n2. If TTY available: Use standard screen spawn (original behavior)\n3. If no TTY: Use detached mode with log capture to capture and display output\n\n## Test Plan\n\n- [x] Added unit tests for `hasTTY` function\n- [x] Added integration tests for screen attached mode output capture\n- [x] Added test for multi-line output handling\n- [x] All 65 tests pass locally and in CI\n- [x] Manual testing with `$ --isolated screen -- echo \"hello\"` now shows \"hello\"\n\n## Case Study Documentation\n\nAdded comprehensive case study documentation in `docs/case-studies/issue-15/` including:\n- Root cause analysis\n- Experimental evidence\n- Solution options evaluation\n- Test logs\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)\nEOF\n)\" 2>&1",
