Claude Code 2.1.299

[What's changed] Added idle compaction in the terminal: a 200K+ token conversation left idle for about 54 minutes is compacted before its one-hour prompt cache expires, so your next message doesn't reprocess it all

[What's changed] Added `CLAUDE_CODE_DISABLE_FILE_MENTIONS` environment variable: Claude gets the paths of `@` file mentions to read with its file tools, not the files' contents

[What's changed] Added `CLAUDE_CODE_IDLE_COMPACT_MIN_TOKENS` to change idle compaction's 200K-token minimum; `"idleCompaction": false` in settings.json turns it off. Both need v2.1.290 or later

[What's changed] Added `size`, `weight`, `mono` and `tabular` to a mod's `Text` and named spacing steps (`xs` to `xl`) to its `Box`; `bold` is deprecated in favor of `weight`

[What's changed] Added `--shutdown-drain-sec` to `claude self-hosted-runner orchestrator`: on SIGTERM it stops polling and gives the poll in flight and running spawn hooks up to that many seconds to finish

[What's changed] Added `/effort` and `/fast` in agent view to set what new sessions start with; a bare `/model`, `/effort` or `/fast` there now opens a picker

[What's changed] Added a one-time note when plan mode won't ask before most edits or commands because bypass permissions is available

[What's changed] Added `--disallow-tools` and a `disallowed_tools` case field to `claude plugin eval` to keep specific built-in tools, such as Agent, out of eval runs

[What's changed] Added `/usage` warnings for max effort, workflows, always-on context and large tool results

[What's changed] Improved the plugin-authoring skill's steps for sharing a mod: Claude asks public or private and checks the files before creating a GitHub repository

[What's changed] Improved the error for creating a worktree at a bare-repository layout's root: it now explains the layout instead of an unrelated git error

[What's changed] Improved artifact watching: a local session can now watch up to 25 published artifacts at once, up from 10

[What's changed] Improved background agent notifications: they now say when an agent is only waiting on its own background work, got a message too late for its result, or was stopped by a usage limit

[What's changed] Changed WebFetch page reads to pick their effort as web searches do: the caller's level on the caller's own model, otherwise the level settings give the small model

[What's changed] Changed Claude in Chrome in Cowork cloud sessions outside auto mode: an approved-site action the safety classifier flags now asks you instead of being refused, unless managed settings apply

[What's changed] Changed cloud session and Remote Control MCP connectors to negotiate MCP protocol version 2026-07-28 by default on installs that fetch no flags; `MCP_PROTOCOL_NEGOTIATION=legacy` opts out

[What's changed] Changed MCP tool descriptions and server instructions from Anthropic's first-party MCP servers at `api.anthropic.com` to reach Claude in full instead of being cut at 4,096 characters

[What's changed] Changed `UserPromptSubmit` hooks to run before a skill or custom slash command expands, so a hook that blocks the prompt now also stops its embedded shell commands

[What's changed] Changed the `turn.start` mod hook to also hear subagents' and teammates' turns, not only the main loop's; tell them apart by `e.agentId` (absent on the main loop)

[What's changed] [VSCode] Improved startup time in workspaces without a Python environment by starting Claude while the Python extension loads

[What's changed] [Cloud sessions] Improved the deploy command shown when you create a self-hosted environment or environment key: it shows in full, wraps between arguments, and has a visible copy button

[What's changed] [Claude Tag] Added the ability for Claude in Slack to delete a canvas it created in a channel when someone asks it to

[What's changed] [Claude Tag] Changed how Claude in Slack corrects a message it got wrong: it edits the message in place and adds a short "Edited" note instead of striking through the old text

[What's changed] Added `$.prompt.media` so a `prompt.submit` hook of a mod installed by managed settings can read the bytes of an image or document attached to the prompt

[What's changed] Added `$.session.identity()` for mods installed by managed settings: how the session is signed in, and its organization and email when managed `forceLoginOrgUUID` lists that organization

[What's changed] Added the skill's frontmatter, source, plugin name and file path to what a mod's `skill.prompt` hook receives

[What's changed] Added a "safe mode" line to the agents view peek panel for background sessions started with `--safe-mode`

[What's changed] Added a field to the attribution block in Claude Code sessions behind a Claude apps gateway; remove the block with `CLAUDE_CODE_ATTRIBUTION_HEADER=0`

[What's changed] Added a `queue` door to the `session.append` mod hook, so a mod can make the transcript's queue records differ from the prompt as sent

[What's changed] Added a note in `/plugin` and `claude plugin validate` naming a mod's hooks that are skipped where an organization manages Claude Code

[What's changed] Improved the startup warning for an unrecognized model ID: it is now one short line under the welcome banner with a docs link, instead of a long raw message

[What's changed] Improved `/reload-skills` to say it re-sends the full skill list to Claude, which is how to get skills back after compaction

[What's changed] Improved the error shown when a worktree cannot be created because its base commit does not resolve: it now says how the lookup ended and the likely reasons, such as a repository without a commit

[What's changed] Changed `/btw` side questions in non-interactive sessions to return a timeout error when still unanswered after 11 minutes

[What's changed] Changed a skill's own front-matter `UserPromptSubmit` hook to first run on the prompt after the one that invokes the skill

[What's changed] Changed the cyber safeguard notice to no longer ask people to apply to the Cyber Verification Program

[What's changed] [VSCode] Improved startup: the model picker and slash command menu now fill in right away in a new window on a folder you've opened before

[What's changed] [Claude Tag] Changed Claude in Slack to join channels with more than 100 members quietly, with no intro message

[What's changed] Fixed a sandboxed shell command being able to write into a `--plugin-dir` folder, whose code Claude Code reloads and runs outside the sandbox

[What's changed] Fixed `claude mcp list`, `claude doctor` and `/status` reporting an empty `.mcp.json` as invalid

[What's changed] Fixed the Claude apps gateway serving models that a policy's `availableModelsMatch: exact` or `deniedModels` blocks; it now answers 400 and leaves them out of its model lists

[What's changed] Fixed the server-managed settings request to Anthropic carrying a third-party gateway's API key when a managed settings file sets `ANTHROPIC_BASE_URL`

[What's changed] Fixed a mod's `tool.describe` or `prompt.section` answer that changed after `$.ui.invalidate` never reaching Claude; the new answer is now sent on the next turn

[What's changed] Fixed sandboxed commands on macOS being able to read or write a denied path by its real location when the denied path passes through a symlink

[What's changed] Changed MCP allow rules to reach only the server they name: `mcp__a` no longer allows a server named `a__b` or `a_`; write `mcp__<server>__*` with the server's whole normalized name

[What's changed] [Cloud sessions] Fixed the Sessions and Runners lists in a self-hosted environment's admin details saying the list is empty when a search just has no matches

[What's changed] Fixed the error for a denied cloud session, which could point to the wrong organization when a key from `apiKeyHelper` was in use

[What's changed] Fixed Edit and Retry in Cowork and claude.ai cloud sessions failing on a message stopped while its `UserPromptSubmit` or mod `prompt.submit` hooks were still running (regression in 2.1.296)

[What's changed] Fixed an agent teammate started without a description keeping part of a credential from its prompt in the task description shown for it

[What's changed] Fixed the claude.ai view of a Remote Control or cloud session freezing when a large batch of events could not finish uploading over a slow connection

[What's changed] Fixed double-clicking a word in an expanded transcript row in fullscreen mode collapsing the row instead of selecting the word

[What's changed] Fixed `/btw` jumping the transcript to the bottom when asked while scrolled up in fullscreen

[What's changed] Fixed sandboxed commands failing on WSL2 with `bwrap: Can't mkdir /mnt/c/Program Files/ClaudeCode` when the sandbox can write to the Windows drive

[What's changed] Fixed scheduled wakeups (ScheduleWakeup) not firing while a background task was running in Agent SDK, IDE and `claude remote-control` sessions

[What's changed] Fixed sign-in, MCP servers and project trust appearing lost on Linux after a sandboxed command left an empty `.config.json` in the config directory

[What's changed] Fixed `/sandbox` reporting success when its setting could not be saved because the project folder is not writable; it now says nothing changed and why

[What's changed] Fixed SDK and headless sessions staying in auto mode after the host switched to a model that doesn't support auto mode

[What's changed] Fixed MCP servers named `constructor` or `prototype` in an MCP config never being connected

[What's changed] Fixed tools of an MCP server named `constructor` or `toString` asking for permission in auto mode and bypass permissions mode

[What's changed] Fixed a spurious "synced[0] commands path not found" plugin error at startup when another Claude Code process had just updated a claude.ai-synced plugin

[What's changed] Fixed the Artifact tool advising a retry when a publish that requests connectors or other access was refused by the server or a proxy (HTTP 403); it now says so and what to tell the user

[What's changed] Fixed Cowork cloud sessions staying on an old account plugin after a plugin reload that timed out or a restart that reused a recent sync

[What's changed] Fixed document blocks being dropped from your own message sent while Claude is working

[What's changed] Fixed high memory use after resuming a cloud or Remote Control session that had run many subagents

[What's changed] Fixed `/usage`, the approaching-limit warning (terminal and VS Code) and the status line sometimes showing more than 100% used (anthropics/claude-code#92238)

[What's changed] Fixed deny and ask rules for an MCP server (`mcp__<server>`) not applying when the server's normalized name contains a double underscore

[What's changed] Fixed long conversations losing newly attached images on every turn after one oversized image was refused by the API

[What's changed] Fixed feature flag, startup, fast mode, profile and feedback requests to Anthropic carrying the API key configured for a third-party gateway (`ANTHROPIC_BASE_URL`); Anthropic API keys are still sent

[What's changed] Fixed a regression in 2.1.296 where cloud and headless sessions could run an approved tool call twice if a new message arrived as the session resumed after a restart

[What's changed] Fixed `claude mcp list`, `claude mcp get` and subagent MCP servers starting a server that a policy check blocks; it is now reported as blocked without being started

[What's changed] Fixed `$.http.fetch` in mods refusing a `304`, `204` or `205` response that declares a `Content-Length` over the 4 MiB body limit

[What's changed] Fixed `/config` push notification toggles sending your account the previous setting instead of the one you just chose

[What's changed] Fixed a cloud session leaving a reply unfinished when its worker was replaced just after the reply hit the output token limit

[What's changed] Fixed Read failing on PDF page ranges in remote sessions on Linux that run without elevated privileges

[What's changed] Fixed self-hosted runner sessions shutting down MCP servers added through an `--exec-path` wrapper's own `--mcp-config` when connectors change mid-session

[What's changed] Fixed `forceLoginOrgUUID` and `forceLoginMethod` from MDM or the managed-settings file being hidden or replaced by server-managed settings

[What's changed] Fixed `--bare` sessions leaving out an MCP server named `constructor` or `prototype` that `--channels` asked for

[What's changed] Fixed resuming a conversation from before `/clear` reattaching to the Remote Control session of the conversation after it

[What's changed] Fixed `/btw` side questions in non-interactive sessions not being cancelled when the session ends, and running a second time when the same request arrived again mid-run

[What's changed] Fixed sandbox `denyRead` and `allowRead` globs with braces, parentheses or backslashes in a folder's name being read differently by Claude Code's settings checks than by the sandbox

[What's changed] Fixed sandbox glob `allowRead` and `allowWrite` entries not being re-checked when the directory they start from is replaced by a symlink

[What's changed] Fixed worktree-isolated sessions accepting some awk programs the isolation guard should refuse

[What's changed] Fixed `claude mcp add <name> -- <command> --background` being started as a background session

[What's changed] Fixed a custom slash command's embedded shell line running twice when a newer message interrupted the command while its prompt was being checked

[What's changed] Fixed MCP OAuth sign-in, token refresh and sign-out not sending configured `headers`/`headersHelper` values, which broke servers behind an authenticating proxy

[What's changed] Fixed plan mode running a write (an MCP tool's, a file's, a shell command's) that a `PreToolUse` hook or a mod's `tool.check` hook allowed

[What's changed] Fixed background subagents in auto mode sometimes sending their final report twice, once as the result and once as a message

[What's changed] Fixed replies cut off at the output token limit ending the turn silently, with no retry or error, after a request fell back to non-streaming mode

[What's changed] Fixed photos sent over Remote Control being dropped when their copy could not be saved on your computer; Claude now still sees the photo

[What's changed] Fixed files sent over Remote Control sometimes not arriving in long-running sessions

[What's changed] Fixed files of 30 to 35 MiB sent over Remote Control or to a cloud session not arriving

[What's changed] Self-hosted runner: Fixed sessions that wrote output before their first turn being left with no release timer, ignoring `--retire-at` and delaying shutdown

[What's changed] Improved the error shown when a cloud session is refused because your claude.ai login was rejected or has expired: it now tells you to sign in again with `claude auth login`

[What's changed] Improved the Skill tool's "Unknown skill" error to suggest a skill's listed name when Claude wrongly adds the `anthropic-skills:` prefix to it

[What's changed] Changed actions a plugin hook can block to be refused, not let through, when the hook cannot be handed them or cannot hand back its answer; a tool that already ran has its result withheld

[What's changed] Changed MCP requests in cloud and self-hosted runner sessions to no longer follow HTTP redirects from the session's MCP proxy

[What's changed] Changed skill and command loading: one whose file or folder name has hidden, direction-changing or blank-like characters, `<` or `>` is no longer offered until renamed; such a `name:` is ignored

[What's changed] Changed agent `tools:` lists to take only the named MCP server's tools; list a server whose name contains `__` as `mcp__<whole name>__*`

[What's changed] Changed auto mode in Cowork cloud sessions: a `PermissionRequest` hook can no longer approve shell commands or subagents; those prompts wait or are denied

[What's changed] Changed the errors shown when `/ultrareview` can't upload a repository to stop suggesting `git add .`, which could stage or commit untracked files such as `.env`

[What's changed] [VSCode] Fixed an unsent prompt and its attachments being lost when switching to another session and back

[What's changed] [Cloud sessions] Fixed a memory spike that could crash a session when many of its existing output files were re-sent to it at once

[What's changed] [Claude Tag] Fixed Claude in Slack staying silent on untagged posts that a channel's own instructions tell it to answer, such as posts that tag someone else, in channels with guests

[What's changed] [Claude Tag] Fixed Claude in Slack reporting a reply to another channel's thread as posted when it isn't a member there; it now says the reply wasn't delivered and how to fix that

[What's changed] [Claude Tag] Fixed Claude in Slack sometimes ending a turn without posting its answer when a self-hosted runner's image has no python3

[What's changed] [Code Review] Fixed Code Review's monthly spend-limit comment and check-run card sending admins to Claude Code settings; they now link the Usage page, where that limit is set

[What's changed] Added support for turning off the attribution block in Claude Desktop's Code tab: set `CLAUDE_CODE_ATTRIBUTION_HEADER=0` in the `env` of a Claude apps gateway's `code` policy

[What's changed] Fixed a mod that submits a prompt at the end of every turn keeping a headless run going past `--max-turns`, `--max-budget-usd`, an interrupt, or the end of the host's conversation

[What's changed] Fixed cloud sessions sometimes showing the model's follow-up text after a tool group's one-line label

[What's changed] Fixed the Write and Edit tools creating a mod in a session's mods folder without asking in accept-edits mode when the config directory's path has no `.claude` in it

[What's changed] Fixed installed mods that kept running in an open session after being turned off remotely; they now unload between turns

[What's changed] Fixed memory growth under heavy debug logging (`--debug`, `--debug-file`), and a hang on exit when the debug log is on a disk or network mount that stops accepting writes

[What's changed] Fixed memory growing without bound when debug output goes to stderr and the parent process stops reading it

[What's changed] Fixed rm prompts on shell `-c` scripts that don't run `rm`. An rm built at run time in a script Claude Code can't read no longer prompts unless `CLAUDE_CODE_STRICT_INLINE_SHELL_RM_PROMPT=1`

[What's changed] Fixed a mod's `prompt.submit` rewrite being silently dropped, sending the prompt as typed, for some prompts with a pasted image or an image that can't be read

[What's changed] Fixed a Remote Control prompt being lost when another queued prompt in the same batch failed to deliver

[What's changed] Fixed a Remote Control prompt that had passed its hooks being dropped from prompt history when Stop interrupted the next queued prompt's hook

[What's changed] Fixed Claude in Chrome asking for permission while no browser is connected; it now says the extension is not connected

[What's changed] Fixed the fullscreen "Update installed" notice being hidden behind the idle "/clear to save tokens" hint; it now shows beside the hint

[What's changed] Fixed a mod hook, with or without a `.catch`, being run again without end when it waits on another mod's noun that does its work outside the call

[What's changed] Fixed streams through a custom `ANTHROPIC_BASE_URL` being aborted after 180 seconds with no data arriving; they now wait 300 seconds, whether or not feature flags are loaded

[What's changed] Fixed a settings file being ignored when `enabledMcpjsonServers` or `disabledMcpjsonServers` held a single server name (letters, digits, - or _) as a plain string

[What's changed] Fixed `claude plugin test` pausing a hook's time budget while a served `$` method it had called kept making `$` calls after answering

[What's changed] Fixed plugin hooks being skipped when they pass a very deeply nested tool input or message on with next()

[What's changed] Fixed a value a mod's hook passes to `next()`, returns, or sends to a `$` method being refused whole when one of its getters throws a `RangeError`; now only that key is refused

[What's changed] Fixed wrapped text mixing CJK or emoji with Latin words losing its last line or leaving a blank row at some terminal widths

[What's changed] Fixed a cloud session sometimes ignoring the answer to a permission prompt or a question when the answer was given while the session's worker was being replaced

[What's changed] Fixed bold, italic and other nested text styles running over table borders or being lost on wrapped rows

[What's changed] Fixed Cowork cloud sessions running the old version of an account plugin changed, removed or disabled from another device until the session restarted

[What's changed] Fixed the `plugin_loaded` telemetry event reporting `has_hooks` as false for plugins whose hooks are a hooks module, built-in plugins included

[What's changed] Fixed images attached while Claude is working (VS Code, desktop app, SDK) being sent at full size, which led to repeated image errors in long conversations

[What's changed] Fixed the image coordinate hint being missing or slightly off for large near-square images on newer models

[What's changed] Fixed a mod's hot reload ignoring a fix saved right after a failed reload; saving a mod file without changing it no longer reloads the mod

[What's changed] Fixed mods loaded from source files being refused when a hook hands `$` to a function declaration imported from another file of the mod

[What's changed] Fixed scheduled tasks being announced for the wrong minute: the scheduling tools now report each job's actual next run time

[What's changed] Fixed mods' hooks being handed values with `__proto__` keys silently removed, which could skip a `tool.check` guard on a tool call another mod made

[What's changed] Fixed `claude -p` saying nothing when a settings file fails validation: text-output runs now list the file and the invalid entry on stderr

[What's changed] Fixed long pastes in terminals without bracketed paste losing all text after an invisible control character, such as a mis-decoded curly quote

[What's changed] Fixed managed settings and organization policy not being fetched when the stored login's plan was changed locally on machines whose MDM or managed-settings file sets `forceLoginOrgUUID`

[What's changed] Fixed MCP connections over HTTP hanging for 30 seconds and failing when a server never ends the body of its reply to a notification (anthropics/claude-code#99014)

[What's changed] Fixed MCP servers added to a running headless or SDK session being connected before some policy checks ran; a blocked server is now reported as failed without being contacted

[What's changed] Fixed `/reload-plugins` not loading a plugin installed from another terminal a moment earlier

[What's changed] Fixed blank rows appearing under CJK and emoji text squeezed into a one-cell column, as in a very narrow terminal

[What's changed] Fixed text cut in the middle beside wide characters leaving a cell unused or being cut twice, and an emoji vanishing where a color changed inside it

[What's changed] Fixed bare mode notices in background sessions telling you to restart without `--bare`, which keeps the mode; they now name `/stop` and `claude --resume`, as safe mode ones do

[What's changed] Fixed `←` not saying why it stayed put over a queued message while Remote Control is on

[What's changed] Fixed Enter answering a question or permission prompt that had been held back while you typed an unsent message

[What's changed] Fixed a file attached to a message in a remote session being left out when its download stalled part way; the download is now tried again

[What's changed] Fixed queued prompts sent as content blocks over `--input-format stream-json` running together without a line break when merged into one turn

[What's changed] Fixed `claude plugin eval` passing runs that the API refused: a run that ends on an API error now scores 0 without grading and makes the suite exit 1

[What's changed] Fixed permission prompts cutting off or wrapping too early when the reason text contains keycap or joined emoji

[What's changed] Fixed background sessions started with `--safe-mode` silently leaving safe mode when the session was woken or restarted

[What's changed] Fixed scheduled tasks and loops firing again after every turn, or firing early, during the repeated hour when daylight saving time ends

[What's changed] Fixed the diff view listing a new file whose name begins or ends with a space under the wrong name

[What's changed] Fixed MCP tool calls in headless and SDK sessions sometimes failing or running twice when a background reconnect closed the connection they were running on

[What's changed] Fixed a prompt or reply of `--bg` or `--background` to a background session being taken for the flag, which could start new sessions over and over instead of delivering it

[What's changed] Fixed `--worktree` sessions leaving a folder behind in `.git/worktrees` in repositories using git's reftable ref storage

[What's changed] Fixed `claude self-hosted-runner` sessions using Anthropic-managed git showing tracked files as staged deletions when starting in a reused clone whose remote is still empty

[What's changed] Fixed Ultracode not being announced to scheduled tasks and other delivered headless turns when `ultracode` is on in settings

[What's changed] Fixed the Artifact tool reporting a spurious one-line difference against the live page, and refusing the publish, when a large page with a line break after `<head>` is published again unchanged

[What's changed] Fixed `$.ui.open` reporting a mod's pane as placed in sessions where no surface draws it, such as Claude Code for VS Code and `claude -p`

[What's changed] Fixed the `agent.spawn` mod hook not running when a finished subagent or a killed teammate is resumed: the hook's event now carries `resume`, and a mod can refuse it

[What's changed] Fixed `claude plugin validate` rejecting a mod's `$.state` references when `plugin.json` has no `types` key and the contract is at `./types/index.d.ts`

[What's changed] Fixed a mod's `dimColor` text looking the same as plain text under the dark ANSI theme and on 16-color terminals

[What's changed] Fixed `SendMessage` not finding a subagent by name after the CLI restarted and resumed the session (names given before the last compaction still need the agent ID)

[What's changed] Fixed cloud sessions sometimes leaving a message unanswered when the worker was replaced right after a compaction

[What's changed] Fixed cloud sessions and `CLAUDE_CODE_RESUME_INTERRUPTED_TURN` sometimes answering a finished turn again after a restart, when a tool ended the turn and a skill loaded in the same step

[What's changed] Fixed a user-installed mod's `$.env.set` changing the environment or shell prefix that command hooks from managed settings start with

[What's changed] Windows: Fixed the process-liveness check leaving orphaned PowerShell processes behind on busy machines until memory ran out

[What's changed] Windows: Fixed PreToolUse and PermissionRequest hooks that set no shell failing open when Git for Windows isn't installed; a guard that fails now blocks the call

[What's changed] Windows: Fixed Bash commands failing with "command not found" for a whole session when Git Bash did not report its PATH at startup

[What's changed] Improved enforcement of managed permission rules, managed hooks and organization MCP tool names against user-installed mods

[What's changed] Improved memory and disk use when PDFs are @-mentioned: their bytes are no longer kept in the session transcript

[What's changed] Improved sandboxed Bash on Linux: Esc and Ctrl-C now work while wildcard read rules are being expanded for a command

[What's changed] Changed plugin hooks and workflow scripts to refuse values they hand back that nest deeper than 28,000 levels, with an error naming the limit (workflow scripts allowed 100,000)

[What's changed] Changed requests to claude.ai's connector proxy and to Anthropic-hosted MCP servers to no longer follow HTTP redirects; redirects by a connector's own server are unaffected

[What's changed] Changed `ui.render` trees in `claude plugin test`: each mod's Box or Text root now carries `part: { plugin }` naming the mod, so exact-tree assertions must include it

[What's changed] Changed `claude plugin test` to fail a call to a mod's served `$` method that has not answered within ten seconds, as a session does

[What's changed] Changed the resume command printed at exit: it names the session by its ID and no longer by its name, so that nothing in a session name can run when the line is pasted

[What's changed] Changed the resume command printed at exit of a worktree session: it uses `-w` and `-r` if the long flags do not fit the terminal. If neither fits a kept worktree, rows above it say where to run it

[What's changed] [VSCode] Fixed unused blank chats keeping a background Claude process running after starting a new conversation

[What's changed] [VSCode] Fixed the mic button showing an internal error message when you are signed out of claude.ai; it now offers to sign you in

[What's changed] [Cloud sessions] Fixed saving an edited routine silently moving it to a different environment when its own had been deleted or wasn't in the list; the routine now keeps its environment

[What's changed] [Cloud sessions] Fixed Sessions search in a self-hosted environment's admin details finding nothing when you paste the session ID from a session's link

[What's changed] [Cloud sessions] Changed deleting a self-hosted environment to turn off its routines right away, with the reason shown on each routine, instead of leaving their runs to fail

[What's changed] [Remote Control] Fixed Remote Control sessions whose computer can't be reached still appearing to send your messages; your text now stays in the box and Send is off until it reconnects

[What's changed] Self-hosted runner: Improved what `setup` and `doctor` say when the runner's machine has no git credentials
