Claude Code v2.1.199 の更新内容

What's changed

• Stacked slash-skill invocations like /skill-a /skill-b do XYZ now load all leading skills (up to 5), not just the first

• Fixed SSL certificate errors (TLS-inspecting proxies, missing NODE_EXTRA_CA_CERTS, expired certs) burning retries before showing actionable guidance — they now fail immediately with the fix hint

• Fixed streaming responses being discarded when the API emits a mid-stream overloaded/server error after partial output — the partial is now kept with an incomplete-response notice

• Fixed subagents cut off by a rate limit or server error silently failing instead of returning their partial work to the parent

• Fixed subagents reporting API errors (e.g. usage limit reached) as successful results — the error is now reported to the parent agent

• Fixed the background-agent daemon on Linux killing itself and every running agent every ~50 seconds after an unclean shutdown left a corrupted worker record

• Fixed background agents failing to cold-start over SSH on macOS with "Could not switch to audit session" (regression in 2.1.196)

• Fixed claude stop being silently undone when it raced a background-agent respawn — the respawn now honors the stop

• Fixed background job progress indicators stalling for minutes while the job ran long commands

• Fixed background sessions on memory-starved machines showing a generic error — they now indicate low memory and suggest freeing resources

• Fixed remote sessions briefly flapping between Working and Idle in the agent view when a background agent completes

• Fixed idle subagents vanishing from the agent panel while other subagents were still working; surplus idle agents now collapse into an expandable summary row

• Fixed typing /model or /fast while viewing a subagent silently opening the lead's model picker — a notice now explains the command applies to the lead

• Fixed SessionStart, Setup, and SubagentStart hooks silently hiding stderr when exiting with code 2 — the error is now shown in the transcript

• Fixed claude --dangerously-skip-permissions daemon being treated as a chat prompt instead of running the subcommand

• Fixed SendMessage silently misrouting when a re-spawned agent reuses a previous agent's name — the tool now detects the mismatch and asks the caller to retarget

• Fixed opening or resuming a session with no new messages needlessly growing the transcript file

• Fixed backgrounding a session with ← or /background dropping its /color from the agent view row

• Fixed resetting a corrupted config file from the startup recovery dialog destroying it unrecoverably — it now backs up the file first

• Fixed Claude in Chrome repeatedly opening the reconnect page when sessions run from different builds or config directories

• Fixed plan mode not prompting for state-changing browser tool calls; read-only browser_batch calls are now correctly auto-allowed

• Transient server rate-limit errors (429s unrelated to your usage limit) are now retried automatically with backoff for subscribers instead of failing the turn

• CLAUDE_CODE_RETRY_WATCHDOG now raises the default retry count for non-capacity transient errors to 300 and lifts the cap of 15 on CLAUDE_CODE_MAX_RETRIES

• claude agents session rows now show pull-request links as bare #N without the redundant "PR" label
