Known breaks in Claude Code from github.com/anthropics/claude-code, with quoted workarounds and fixed-in versions where they exist.
Type the version you're about to install (or just upgraded to). Lists tracked issues that mention it. Same data as /api/issues/claude-code.json.
Pulled from public GitHub issues updated in the last 45 days and filtered for always-on problems: install and update breakage, crashes and hangs, gateway/daemon trouble, auth, and headless setups. Ranked by engagement, weighted toward always-on, self-hosting, install/update, crash, auth, MCP and daemon problems (cosmetic desktop-UI issues are down-weighted). Workarounds and "fixed in" versions are quoted only when the issue or its top comments state them. Severity is an automatic estimate from labels, keywords, and engagement, not an official rating.

Claude Code versions 2.1.100 and 2.1.101 consume ~20,000 more cachecreationinputtokens per request than v2.1.98, despite sending fewer bytes in the request payload. The inflation is server-side and version-specific (likely User-Agent…
Downgrade to v2.1.98 or earlier. Check `~/.local/share/claude/versions/` for available binaries, or use `npx claude-code@2.1.98`.
When Claude Code generates a compound bash command using && (e.g.: cd /some/path && git add file && git commit -m "msg"), the permission approval prompt incorrectly identifies cd as the action requiring approval, showing a cd: permission…
On Windows 11, the Claude Desktop window behaves as a topmost window: it stays drawn above other applications even after another window is focused and brought over it. There is no in-app setting to turn this off. This is the Windows…
On a Max subscription, the same workload uses about 1.8× more of the 5-hour window when it runs headless (claude -p --input-format stream-json, recorded as entrypoint: "sdk-cli" in the transcripts) than when it runs in the interactive TUI…
Bug Description VS Code extension update ~13 hours ago (Jan 23-24 2026) causes "API Error: 400 due to tool use concurrency issues" on every tool call. CLI works fine, only VS Code affected Error persists through extension reinstall, VS…
downgrade to vscode extension version 2.1.17 fixed the issue `uninstall the extension --> restart vscode --> install extension with 2.1.17 version -> fixed`

This has been reported but was closed for being stale. Reopening in a new ticket. The most recent upgrade to Claude Code regressed on https://github.com/anthropics/claude-code/issues/48550 which was auto closed for inactivity. I cannot…
The Monitor tool now hard-rejects persistent and timeoutms above 3600000 (1 hour) even with persistent set, it rejects with a schema validation error, and even a Monitor started with the maximum now allowed (3600000) is reported as…
Since 2026-10-12 at about 18:18 UTC, every newly started interactive session writes its main-conversation prompt cache under the 5-minute TTL. Headless claude -p runs on the same account, machine, version and model still write under 1…
Claude Desktop 2.2553.1 (macOS 26.6.2, Apple Silicon) Bundled Claude Code 2.1.275 Remote Control in use daily from claude.ai/code while away from the machine When an update is staged, the app waits for a short idle window and then quits…
Claude desktop app: 2.37337.1 Code tab sidebar After a recent update, the Code tab sidebar no longer groups sessions by project/repository. Sessions are now grouped only by environment: "This computer", "Cloud", SSH host (e.g. ubuntu@ )…
I had Claude create a custom sidebar group for each of my 15 project folders and move ~127 sessions into them.
On Claude Max (20x), the weekly "all models" meter went from 0% to 54% in the first 22 hours after the weekly reset. My Claude Code token volume in those 22 hours was nearly identical to the same 22 hours of the previous week. The previous…
What I expect I run local scheduled tasks (routines) in Claude Desktop on my Mac. Each run used to show up as a normal session: in the desktop app's left sidebar, and in Remote Control on my phone, so I could open a run and continue it…
After updating the Claude desktop app, the Routines section is gone from the Code tab sidebar. My local routines still exist and still run on schedule; only the section is missing. The sidebar has no control to show it again. What I found…
After auto-updating to 2.1.269, text inserted by a voice dictation tool (Wispr Flow — clipboard + simulated Ctrl+V) is no longer inserted into the Claude Code prompt when Claude Code runs in the VS Code integrated terminal (Remote-WSL)…
Pin 2.1.268 (`ln -sfn ~/.local/share/claude/versions/2.1.268 ~/.local/bin/claude` + `DISABLE_AUTOUPDATER=1`), or run Claude Code in Windows Terminal instead of the VS Code integrated terminal.
A mod's ui.render output (e.g. an AbovePrompt band with a Button) is drawn in the terminal but never appears in the Claude desktop app or the Claude iOS app when they view the same session through Remote Control. Only mod-initiated…
In an interactive VSCode-extension session, Claude Code declares the MCP elicitation capability during initialize, but auto-declines every elicitation/create request without showing any UI. The same session can render permission prompts…
Am I the only one no longer able to figure out how to switch off automatic work tree creation in the newest version. Updated to the latest claude code to do development on the desktop app and now it seems I'm forced into using worktrees?…
After updating Claude Desktop, the Routines section disappeared from the Code tab sidebar. Previously every scheduled task run appeared there, so I could see at a glance which tasks ran, when, and whether they succeeded. Now there is no…
On macOS, MCP OAuth entries in the shared Keychain item Claude Code-credentials get rewritten with empty accessToken/refreshToken (and no clientId) while the refresh tokens are still valid, when several claude processes touch the store…
With Allow network egress = ON and Domain allowlist = "All domains" (Settings -> Capabilities -> Code execution), the session egress proxy still rejects every host outside a small built-in allowlist with 403 on CONNECT. This is a…
Published artifacts no longer show a "Version history" option anywhere: not in the claude.ai web viewer's title menu, and not in the Claude desktop app's artifact side panel. Earlier versions are still being saved (each publish returns a…
A user-configured stdio MCP server connects successfully (status: connected) but always reports toolcount: 0, across brand-new sessions, app restarts, and even a full OS reboot. The problem persists indefinitely — no retry ever recovers…
On Windows, the Claude Desktop app's stealth auto-update deadlocks. After an idle timeout, the app tears down its window and any running Claude Code sessions and logs beforeQuitForUpdate handler fired, going down for update, but the main…
`tasklist /apps | findstr /i claude ; Stop-Process -Id -Force` Then relaunch.
The security-guidance plugin (2.0.8) runs hooks/sg-python.sh on SessionStart, every UserPromptSubmit, every PostToolUse on Edit|Write|MultiEdit|NotebookEdit, PostToolUse on Bash, every Stop and every SubagentStop. On every one of those…

A session served by a long-running claude remote-control host (server mode, same-dir spawn) can't be used again after it's archived and then unarchived from claude.ai. The web UI accepts the unarchive, but a message sent to the session…
`claude remote-control --session-id ` in the same directory. This starts a separate single-session host. - Calling `bridge/reconnect` for the session, as above. This puts it back into the existing host.
This is not a cosmetic redesign. My classic claude.ai chat projects, which I used as sealed folders of separate private conversations with their own instructions, were converted to the coordinator-based Projects without my consent, without…
In the Claude desktop app (Code tab), Remote Control only stays connected while a session's process is running. Once a session finishes its turn and goes idle, the app shuts its process down, and the Remote Control link drops with it. The…
The filter button next to "+" at the top of the session list used to let you show archived sessions. After the update it doesn't. The only way to them now is "View All", which opens a whole separate panel listing every session. You archive…
On macOS 12 (Monterey, Intel), the Desktop app's model picker shows Opus 5.5 greyed out with the tooltip "Update Claude to use this model on this computer", while the app's own update check reports "You're using the latest version." The…
This is about the Claude in Chrome browser extension, not the Claude Code CLI. In Vivaldi, the extension's new side panel (the embedded claude.ai Cowork interface) never works. It only shows: Up to extension 1.0.93, you could work around…
After upgrading claude-desktop from 2.31226.1 to 2.37337.1 (apt, stable) on Ubuntu 26.04 (GNOME/Wayland), every click on the "+" next to a project group in the Code tab sidebar shows a toast: "Couldn't switch environment: the Local…

Every MCP tool call that omits an optional parameter is rejected with a Zod-style invalidtype / expected: "nonoptional", received: "undefined" error for that parameter — even though the tool's own JSON Schema declares a default for it…
explicitly pass `fields` and `attribute_keys` (e.g. as a real list, or as the literal string `null` for list-typed fields — note this is not JSON `null`, it becomes the one-element list `["null"]` server-side, which is itself a separate minor bug but harmless for read calls).
After updating VS Code, the Claude Code panel is blank when connected to WSL (Ubuntu). The extension activates normally and authentication works (Output log shows no errors), but the webview fails to load its files: GET…
After updating Claude Code to the latest version in order to use Opus 5.5, Auto Mode started blocking legitimate, user-directed actions in an existing multi-session repository workflow. This workflow had been used repeatedly before the…
Disable Auto Mode for the affected sessions. - Use `acceptEdits`. - Add explicit permission allow rules for the required commands.
In a Cowork conversation on Claude Desktop for Windows, tools work normally in text mode (including a local MCP server — Obsidian — that reads/writes my vault). As soon as I switch the same conversation to voice mode, the tools become…
Title: Remote Control sessions not accessible from claude.ai/code without session-specific URL The claude.ai/code landing page and the Code button in claude.ai both redirect to GitHub onboarding with no way to skip. This makes it…
When resuming an existing conversation in the Claude Code desktop app, the session gets stuck with: "Can't reach your computer — It may be asleep or offline. This session will reconnect when it's back." The message never clears while…
