docs: Add bug report for VSCode extension installation regressionBrowse files

Documents the "1: 1" error that occurs when using /ide command
in Homespace environments. The error appears to be caused by
incorrect parsing of subprocess execution results where the
error field receives the exit code instead of the actual error
message from stderr.

Includes:
- Root cause analysis of the error pattern
- Timeline of when the regression was introduced
- Temporary workaround for affected users
- Required fix description

	1	+# VSCode Extension Installation Regression: "1: 1" Error
	2	+
	3	+Reported: 2025-12-16
	4	+Status: Under Investigation
	5	+Slack Thread: https://anthropic.slack.com/archives/C07VBSHV7EV/p1765922691961929?thread_ts=1765922103.768169&cid=C07VBSHV7EV

	7	+## Description
	8	+
	9	+Users are unable to use the VSCode IDE integration when running Claude Code in a Homespace (containerized environment). The `/ide` command initially reports success, but a few seconds later an error appears.
	10	+
	11	+### Error Message
	12	+
	13	+```
	14	+IDE: ✘ Error installing VS Code extension: 1: 1
	15	+ Please restart your IDE and try again.
	16	+```
	17	+
	18	+## Steps to Reproduce
	19	+
	20	+1. Run Claude Code in a Homespace environment
	21	+2. Execute `/ide` command
	22	+3. Observe initial success message
	23	+4. Wait a few seconds - error popup appears
	24	+5. Run `/status` to confirm the error
	25	+
	26	+## Root Cause Analysis
	27	+
	28	+### Error Pattern Analysis
	29	+
	30	+The error message `1: 1` follows the pattern from the extension installation error handling:
	31	+
	32	+```javascript
	33	+throw Error(`${result.code}: ${result.error} ${result.stderr}`)
	34	+```
	35	+
	36	+For "1: 1" to appear, the values must be:
	37	+- `result.code` = 1 (exit code from VS Code CLI)
	38	+- `result.error` = "1" (incorrectly set to the exit code instead of error message)
	39	+- `result.stderr` = "" (empty)
	40	+
	41	+### Regression Hypothesis
	42	+
	43	+The async execution result object is incorrectly populating the `error` field with the numeric exit code instead of the actual error message from stderr. This appears to be a regression in subprocess output parsing.
	44	+
	45	+### Timeline
	46	+
	47	+- Working: Last week (user confirmed)
	48	+- Broken: Current version (2.0.59+)
	49	+- Likely introduced: Between versions 2.0.59-2.0.70
	50	+
	51	+## Environment
	52	+
	53	+- Running in Homespace (containerized environment)
	54	+- VSCode Remote development setup
	55	+
	56	+## Temporary Workaround
	57	+
	58	+If experiencing this issue, try:
	59	+
	60	+1. Manually install the Claude Code extension in VS Code:
	61	+ - Open VS Code Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
	62	+ - Type "Extensions: Install Extension"
	63	+ - Search for "Claude Code" (by Anthropic)
	64	+ - Install manually
	65	+
	66	+2. After manual installation, restart your IDE and try `/ide` again
	67	+
	68	+## Related Changes in CHANGELOG
	69	+
	70	+Potentially relevant recent changes:
	71	+- 2.0.64: VSCode: Fixed extension not working on Windows ARM64
	72	+- 2.0.62: Fixed IDE diff tab not closing when rejecting file changes
	73	+- 2.0.61: Reverted VSCode support for multiple terminal clients
	74	+- 2.0.60: VSCode: Added support for multiple terminal clients
	75	+- 2.0.59: VS Code: Fixed .claude.json config file being read from incorrect location
	76	+
	77	+## Fix Required
	78	+
	79	+The fix needs to address how subprocess execution results are parsed, specifically ensuring that:
	80	+1. The `error` field contains the actual error message (from stderr), not the exit code
	81	+2. Proper error handling for when VS Code CLI fails in containerized environments
