Most discussed new issues
- [Bug] Input box stops accepting keystrokes in 2.1.282 after 0-90 seconds into session
- Opus 4.6 regression: catastrophic output quality loss after context window summarization
- [BUG] Replies drift into English right after reading English tool output, despite a CLAUDE.md rule requiring Japanese; corrections do not hold
- [Bug] Weekly usage limit consumption rate increased ~3.6x after September 25 reset
- [BUG] MCP client rejects valid tools/list response due to strict validation of ttlMs/cacheScope fields (Roblox Studio MCP server)
- Critical: Claude ignored explicit 'no upload' instruction and purged GCS version history
- [BUG] Windows Desktop: device bridge handshake never acknowledged for ~18 min (connect frame sent → handshake timeout), survives reboot + app update, then self-recovers
- Scheduled task (routine) runs no longer appear in the desktop sidebar or Remote Control
- Opus 5.5: Severe scope creep and task focus regression compared to Opus 4.6
- [BUG] Windows Desktop: linked computer stuck on "Asleep or app closed", cloud sessions and cloud scheduled tasks fail with "not connected to the bridge" (survives reboot, re-login, device removal, app update)
- Scheduled tasks silently skip their fire window, with host machine and scheduler engine both demonstrably active
- [BUG] Subagent compaction: the preserved segment's tail record is never written to the subagent transcript, and unlike #97316 it is never recovered
- Windows: claude.exe session processes accumulate and are never terminated, causing high RAM/disk usage over a work day
- [BUG] VS Code extension: slash-command and `/goal` messages never collapse, so long /command arguments fill the chat panel
- [BUG] Headless `claude -p` (entrypoint `sdk-cli`) uses ~1.8× more of the 5-hour window per token than interactive `cli`, same workload
- Discord channel plugin: inbound notifications silently dropped on CC 2.1.278 (typing fires, no session turn) — resurfacing #86566
- [FEATURE] Setting to hide or dismiss the weekly usage limit warning banner ("You've used 75% of your weekly limit")
- [BUG] A changed MCP tool description never reaches a session that already loaded the tool, even after reconnect or --resume (deferred_tools_record is replayed)
- [Bug] Claude Code executes destructive commands despite explicit user intent to perform action manually
- [BUG] Artifact "Version history" removed from viewer menu across Claude Code, Cowork and claude.ai – saved versions unreachable (related to #95442)
