Claude Code 2.1.312

[What's changed] Added `oidc.user_id_claim` to the Claude apps gateway, to identify people by an id_token claim other than `sub`, such as Microsoft Entra ID's `oid`

[What's changed] Changed Bedrock, Vertex, Foundry and Mantle to use the shorter system prompt for model names Claude Code doesn't recognize, such as custom deployment names and inference profile ARNs, even when they front Sonnet or Haiku; set `CLAUDE_CODE_SIMPLE_SYSTEM_PROMPT=0` to keep the full prompt

[What's changed] Changed automatic model switches after a flagged message to also cover model names Claude Code doesn't recognize, such as custom deployment names; set `CLAUDE_CODE_DISABLE_REFUSAL_FALLBACK=1` to turn them off

[What's changed] Added click to send: in fullscreen, clicking the "to send now" hint under a queued message sends it right away, as its key does

[What's changed] Improved the prompt's effort indicator: a change made mid-task now says it may wait for your next message, and the note clears when it no longer applies

[What's changed] Improved WebFetch errors in cloud sessions: a host that does not resolve is now explained as possibly outside the allowed network domains, so Claude names the host to allow

[What's changed] Changed usage limit messages to call the 5-hour window the "5-hour limit" instead of the "session limit"

[What's changed] Changed cloud sessions started from the CLI to get their names and branch names from the server

[What's changed] Changed prompt and agent hooks to run at most 24 at a time per session, sub-agents included, plus at most 12 that have waited longer than their event's timeout; a `timeout` under 1 second now counts as 1 second

[What's changed] Changed a subagent's `autoCompactWindow` to lower the window set by `CLAUDE_CODE_AUTO_COMPACT_WINDOW`, where it had no effect before; it still never raises that window

[What's changed] [VSCode] Changed usage limit resets to show a clock time ("Resets at 3:10 PM") and to say "5-hour limit"

[What's changed] [Cloud sessions] Added an effort level to the model picker when you create or edit a routine that runs in the cloud

[What's changed] [Cloud sessions] Added a Bash editor with colors, line numbers and a Copy button to the setup script box in cloud environment settings

[What's changed] [Cloud sessions] Improved the step shown when Claude adds a repository to a cloud session: opening it now shows a short table of what happened instead of raw JSON

[What's changed] [Claude Tag] Improved Claude Tag's retry notice in Slack to name the model in use, or say rate limits were hit, instead of a generic API error

[What's changed] Fixed Claude overwriting a very large CLAUDE.md, rules file or @-included file in a subdirectory after seeing only its start; Write now asks Claude to read it all or edit in place

[What's changed] Fixed managed settings and organization policy not being fetched for the rest of the session after signing in from the VS Code extension

[What's changed] Fixed per-directory and `paths:` skills not being found after a Bash `cd` deeper into a git repository

[What's changed] Fixed a command with an invalid name stopping all commands from loading, which could leave `claude -p` with no output

[What's changed] [VSCode] Fixed sessions ending on a bare exit code when your organization's settings couldn't be loaded or were refused at startup; the tab now says why and offers Retry or Sign in again

[What's changed] [Cloud sessions] Fixed resending an unchanged message after a failed send in a cloud session sometimes running it twice

[What's changed] [Claude Tag] Fixed a Claude Tag channel's on/off switch and agent settings falling back to workspace defaults when an older private Slack channel goes public and gets a new ID

[What's changed] [Claude Tag] Fixed Claude in Slack not replying in channels whose environment has network access set to None

[What's changed] [Code Review] Fixed Code Review reviewing an outdated commit, or none at all, when GitHub delivered a push event late; it now reviews the pull request's current commit

[What's changed] Fixed a rare case where the first reply after resuming a session in the terminal could be missing the next time the session was resumed

[What's changed] Fixed the Read tool sometimes failing on PDF pages with "pdftoppm failed: Could not write image" when the clean-up of old session files ran at the same time

[What's changed] Fixed the spinner, OpenTelemetry `effort` values and transcripts naming a newly picked effort level during a task before the model applied it; they now show the level in force

[What's changed] Fixed the `/model` and `/effort` cache warning saying the re-read waits for your next message; a change made while Claude is working can trigger it sooner

[What's changed] Fixed some sessions showing as waiting on you when the last message only mentioned items waiting on you mid-sentence

[What's changed] Fixed agent view restoring input text on the next launch after it was cleared with Ctrl+C just before exiting

[What's changed] Fixed agent view reopening in shell mode after exiting with Ctrl+D from an empty `!` input

[What's changed] Fixed vim mode `d`, `c` and `y` with a `gj` or `gk` count larger than the lines left deleting or copying text; like Vim, they now only move the cursor

[What's changed] Fixed `/verify` showing a long description meant for Claude in `/help` and the `/` command menu instead of a short one

[What's changed] [Cloud sessions] Fixed a failed cloud environment creation showing its error only as a toast outside the open dialog; it now appears inside the dialog

[What's changed] [Cloud sessions] Fixed Edit in a routine's menu on the Routines page going to the routine's page without opening its edit dialog

[What's changed] [Remote Control] Fixed an unarchived Remote Control session showing as working until a computer reconnected; it now shows as idle

[What's changed] [Claude Tag] Fixed Claude in Slack sometimes posting a file in the wrong thread when it was answering in another thread of the same channel

[What's changed] Changed OpenTelemetry `mcp_server.name` to report the real name of fixed-URL remote MCP servers declared by plugins from the official Anthropic marketplace, instead of `custom`

[What's changed] Changed Claude Code to stop sending the `claude_code.safety_event` OpenTelemetry event
