CLAIM C016 Supported 2026-10-22 GitHub issue #2805 in anthropics/claude-code, opened 2025-07-01 by pm0code, records a report that on Ubuntu Linux, Claude Code creates shell scripts and text files with Windows line endings (CRLF) instead of Unix line endings (LF) even when CLAUDE.md carries explicit instructions; the reporter documents "No such file or directory" errors when executing the scripts and notes a manual sed conversion workaround.
CLAIM C015 Supported 2026-10-20 GitHub issue #87640 in anthropics/claude-code, opened 2026-08-18 by sagimedina1, records a report that the Fable 5 `[reasoning_extraction]` safeguard rejected a message whose user text was the single word `Hi`; the reporter states the classifier guards against prompts attempting to extract chain-of-thought, that nothing in the conversation did that, and that the same session context works normally on Opus 5, pointing at Fable-only safeguards rather than at the conversation.
CLAIM C014 Supported 2026-10-19 GitHub issue #1455 in anthropics/claude-code, opened 2025-05-31 by jennifgcrl, records a report that Claude Code writes its cache data and configs to ~/.claude.json and ~/.claude instead of following the XDG Base Directory specification; the reporter notes CLAUDE_CONFIG_DIR can redirect some files but states the default behavior without configuration should follow the XDG specification.
CLAIM C009 Supported 2026-10-17 GitHub issue #22543 in anthropics/claude-code, opened 2026-02-02 by mjbyt, records a report that after using the cowork feature Claude Desktop becomes extremely slow, alongside a VM bundle file that grows to 10GB, is never cleaned up, and regenerates quickly after deletion; the report documents a cleanup test showing approximately 75% faster performance immediately after removing the bundle, while also noting performance degrades again over time even with the bundle at 0 bytes, suggesting a memory leak or accumulating work.
CLAIM C013 Supported 2026-10-17 GitHub issue #22264 in anthropics/claude-code, opened 2026-01-31 by ilanoh, records a report that when Claude Code makes multiple tool calls in parallel in a single message and one of them fails, all remaining sibling calls in that batch are automatically cancelled with the error "Sibling tool call errored", forcing a retry of all the cancelled calls individually.
CLAIM C012 Supported 2026-10-16 GitHub issue #85891 in anthropics/claude-code, opened 2026-08-11 by kylealty-boop, records a report that on Windows 11 the Claude Desktop main window behaves as a topmost window, staying drawn above other applications even after another window is focused, with no in-app setting to turn this off; the reporter ruled out third-party pinning tools and concludes the topmost flag appears to originate from the app itself.
CLAIM C011 Supported 2026-10-13 GitHub issue #11315 in anthropics/claude-code, opened 2025-11-09 by nenrightld-ux, records a report of a severe memory leak in which Claude Code consumed 129GB of virtual memory, exhausted all 16GB of system RAM, and caused a complete system freeze requiring a hard reboot; the report documents physical memory growing from ~2GB to ~12GB in 30 minutes with no other resource-intensive applications running.
CLAIM C010 Supported 2026-10-12 GitHub issue #5140 in anthropics/claude-code, opened 2025-08-05 by siraj-samsudeen, records a report that user-level permissions in ~/.claude/settings.json are not enforced during command execution even though they appear as loaded in /permissions; the same permissions work when placed in project-level .settings.local.json.
CLAIM C008 Supported 2026-10-10 GitHub issue #68619 in anthropics/claude-code, opened 2026-06-15 by lonlundgren, records a report that subagents recursively spawn child agents 50+ levels deep while ignoring the CLAUDE_CODE_FORK_SUBAGENT=0 setting, burning 1.2M+ tokens in ~30 minutes on a task that should have been a git clone; the report characterizes the behavior as a major regression shipped on or around June 10th.
CLAIM C007 Supported 2026-10-07 GitHub issue #50270 in anthropics/claude-code, opened 2026-04-18 by tpdhd, records a report that starting with v2.1.113 Claude Code switched from a JavaScript entry point to a native glibc Linux binary, completely breaking it on Termux (Android); users see a "native binary not installed" error and are locked out of updates.
CLAIM C006 Supported 2026-10-06 GitHub issue #25128 in anthropics/claude-code, opened 2026-02-12 by emregurhan, records a report that drag and drop is fully operational in terminal/CLI mode but completely non-functional in the VS Code extension chat panel, a regression introduced around v2.1.6 and still unresolved as of v2.1.39; the issue consolidates multiple fragmented reports into a single tracking issue.
CLAIM C005 Supported 2026-10-05 GitHub issue #88747 in anthropics/claude-code, opened 2026-08-22 by DearMaestro, records a report that worktree creation writes an absolute core.hooksPath into config.worktree, causing hooks fired from a worktree to execute scripts from the main checkout on whatever branch it happens to be on; the report characterizes a weakened or removed hook step still passing as a silently removed safety net.
CLAIM C004 Supported 2026-10-04 GitHub issue #46917 in anthropics/claude-code, opened 2026-04-12 by Adrian-Mteam, records a report that Claude Code versions 2.1.100 and 2.1.101 consume approximately 20,000 more cache_creation_input_tokens per request than v2.1.98 despite sending fewer bytes in the client request payload, characterizing the difference as server-side token inflation; subsequent thread discussion records user verification and discussion of workarounds.
CLAIM C003 Supported 2026-10-03 GitHub issue #97854 in anthropics/claude-code, opened 2026-09-28 by timothe-rey, records a report that during a Claude Code session with Auto mode active, the server-side safety classifier intermittently returned no verdict for consecutive tool calls including Bash and ScheduleWakeup, resulting in total failure before self-resolving; subsequent in-thread discussion through October 2026 records further user reports across macOS, Windows, Linux, and WSL debating whether the failure is transient or requires terminating the session.
CLAIM C002 Supported 2026-10-02 GitHub issue #57580 in anthropics/claude-code, opened 2026-05-09 by JDL747, records a report that long Bash-heavy Claude Code Desktop sessions accumulate PTY master file descriptors against /dev/ptmx until macOS's kern.tty.ptmx_max (511) is exhausted, after which forkpty(3)/posix_openpt(3) fail with ENXIO for every process on the machine; the reporter notes that quitting and relaunching Claude releases the descriptors.
CLAIM C001 Supported 2026-09-30 Public discussion records debate whether adopting tool-specific configuration like CLAUDE.md rather than AGENTS.md causes developer ecosystem fragmentation.
