Claude Code v2.1.223

201 entries read diff v2.1.222 → v2.1.223 Markdown

Thirty-two entries in this build are present but not switched on. Two read-only tools, memory_list and memory_read, would let Claude browse documents in connected org and project memory stores, but both stay dark unless the org-memory gate is enabled. Plan mode reminder attachments now carry an artifactsFirst field with reentry, refresh and telemetry handling behind it, and nothing in this build ever sets that field. Skill scanning, workflow saving, background job state files and the daemon lock each gained a branch that routes through a pluggable storage backend instead of the local filesystem, groundwork for host-managed and remote sessions, with filesystem behaviour unchanged when no backend is supplied. Also inert: inlining remote-control image attachments as content blocks, a prompt-variant experiment scoped to two tools, and a scope-expansion path that requests a new user:plugins OAuth scope.

Session recap dropped its experiment check, so /recap, the away summary and the "Session recap" settings entry all work without a gate. Marketplace policy lists gained real matching power: blockedMarketplaces and strictKnownMarketplaces now accept a github entry of the form owner/* to cover every repository under one owner, match case-insensitively, and handle GitHub SSH aliases as the same repo. Managed and admin settings tiers now merge their env blocks key by key instead of letting the winning tier replace the ones below, with an opt-out available. Auto-compact keeps a session inside an assumed token budget when it does not recognize the model name, rather than waiting for the API to report a window. Elsewhere in the 105 shipped entries: /code-review answers to /review, remembers the effort level you last typed, and takes a target argument; a hidden --resume-drops-turn print-mode flag names the turn a truncating resume means to discard; and the SDK stream emits a permission_denied system message when a tool call is refused.

Git remote URLs with an embedded username and password are no longer uploaded verbatim during bridge registration. Credential read failures are now classified by errno, so a transient read error is no longer treated as an empty credential store and no longer lets token refresh proceed as though you had no credentials. On Linux, the bubblewrap sandbox tracks bound paths more accurately so writes are not wrongly redirected into a temporary overlay, and the seccomp helper throws when /proc/self/exe cannot be opened instead of continuing with a half-configured sandbox. Invoking a slash command from a keybinding keeps your draft text and any pasted images. The standalone /review command for GitHub pull requests was removed, its job now handled by /code-review.

Memory Notable

Read-only org memory tools: memory_list and memory_read#

Two read-only tools let Claude browse and read org memory documents, but they stay disabled by default.

memory_list and memory_read are fully built and read-only, but require an org-memory gate that falls back to false.

memory_listmemory_readCLAUDE_CODE_DISABLE_ORG_MEMORYCLAUDE_MEMORY_STORESorgMemoryRead
What

Two new tools let Claude browse and read documents from connected org and project memory stores, but they are off unless the org-memory gate is enabled.

Details
  • memory_list lists connected stores, or documents within one, with paging via a cursor
  • memory_read reads a single document, capped at 102400 bytes, with control characters replaced
  • both are read-only and concurrency-safe
  • refusals are structured: paused, trust_pending, unavailable, unbound, unknown_store, invalid_path, too_large
  • results are prefixed with an instruction-injection warning
  • isEnabled() requires the org-memory predicate chain: the tengu_haze_glass gate with fallback false, CLAUDE_CODE_DISABLE_ORG_MEMORY, CLAUDE_MEMORY_STORES, and the orgMemoryRead setting

Plan Mode Notable not in their notes

Thrifty-sonic narrowed to one model; plan artifacts moved to its own gate#

Plan artifacts now have their own switch instead of riding along with an unrelated experiment.

Plan artifacts read CLAUDE_CODE_PLAN_ARTIFACTS and a gate that falls back to false, so it is off by default.

Feature flag
tengu_thrifty_sonic On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

CLAUDE_CODE_PLAN_ARTIFACTS
What

The thrifty-sonic experiment now only applies to a single model, and the plan-artifacts toggle no longer shares its gate.

Details
  • The thrifty-sonic check short-circuits unless the model resolves to claude-opus-5, before tengu_thrifty_sonic is consulted; its environment variable is unchanged.
  • Plan artifacts now read the environment variable CLAUDE_CODE_PLAN_ARTIFACTS and the gate tengu_basalt_loom, which falls back to false, replacing the tengu_thrifty_sonic read that was there.

Artifacts

Artifact comment replies can be applied as find/replace patches#

Replies to artifact comments can be turned into find/replace edits, with one retry if an edit misses.

A patch applier with retry and failure reasons is built, reachable only via the artifact-comments autoreact feature whose gate is unresolved.

What

A new applier turns a model reply to an artifact comment into a list of find/replace edits against the artifact content, with a single retry when an edit does not land.

Details
  • Walks a list of {find, replace} edits and fails with a reason of "malformed", "not_found", "ambiguous" (the find text occurs twice) or "noop".
  • On the first not_found or ambiguous failure it re-prompts the model once, echoing the offending find text inside fenced DATA and telling it the text "occurs more than once at the point that edit applies (the source as modified by the preceding edits)".
  • Outcomes are reported as edit_patch_apply_failed, edit_patch_retry_fired, patch_retry_echo_refused and stopped_before_patch_retry.
  • Reachable only through the surrounding artifact-comments autoreact feature, whose gate could not be resolved in this build.

Plan Mode Notable

Plan mode artifacts-first field is present but inert#

Plan mode has an artifacts-first switch wired up, but nothing in this build ever turns it on.

The artifactsFirst plan-reminder field has full reentry and telemetry handling, but its supplying helper returns nothing so the branch never runs.

What

Plan mode reminder attachments carry a new artifactsFirst field with full reentry, refresh and telemetry handling, but nothing in this build ever sets it.

Details
  • A change in the value forces a full rather than sparse plan_mode reminder, and a new predicate detects whether a prior attachment carried it.
  • A plan_artifacts_first_active telemetry event fires when the value is set but no attachment has carried it yet.
  • The helper that would supply the value declares its locals and returns them unassigned, so artifactsFirst is always undefined and the branch never activates. The gate that would set it appears to have been folded out at build time.

Skills Notable

User-scope skills and dynamic workflows can be read and written through the storageV5 backend#

Your skills and saved workflows can be read and written through a pluggable storage backend instead of local files.

Skill scanning and workflow saving accept a storageV5 backend; with none supplied everything stays on the filesystem.

What

Skill scanning and workflow saving can route through a pluggable storage backend instead of the local filesystem, which is the groundwork for host-managed and remote storage sessions.

Details
  • The skill scanner takes an optional storageV5 backend; for the user skills directory it lists entries through the backend.
  • For any other base directory it logs a warning and falls back to the filesystem scan.
  • Directory listing for user settings routes through the backend the same way, and workflow saving writes via userConfigDir("workflows", ...) with an ifAbsent precondition when not overwriting.
  • Inactive unless a storageV5 backend is handed in; without one everything stays on the raw filesystem path.

tengu_destructive_command_warning
What

The Bash permission UI now checks the actual command being run rather than a rendered display string, so the destructive-command warning fires when it should.

Details
  • two Bash permission surfaces take the command from e.input.command when it is a string
  • the memoization dependency list was widened to include the input, so the check re-evaluates when the input changes
  • gated on tengu_destructive_command_warning, fallback false

Background Jobs Notable

Background job state and roster writes can route through the v5 storage backend#

Background job files can be stored somewhere other than disk, but nothing switches that on yet.

Job state, sidecar and roster writes have a storage-backend branch with versioned keys; with no backend supplied the filesystem path runs unchanged.

What

Job state.json, the order/stateOrder/group sidecars and the roster orphan-adoption write each gained a branch that goes through a storage backend object instead of the filesystem, using versioned keys, ifAbsent preconditions and size caps. Filesystem behaviour is unchanged when no backend is supplied, and what turns the backend on could not be determined from source.

Details
  • covers job state reads and writes, the three sidecar files, and the orphan-adoption seed write
  • failures on the backend path emit new warn-level diagnostics rather than throwing
  • when no backend object is handed in, the original filesystem path runs untouched

Daemon Notable

Daemon lock can now live in the v5 storage backend#

The background daemon's lock can live in a storage backend instead of a file on disk.

Read, acquire, delete and status all accept a v5 storage backend for the daemon lock; it only applies if a caller supplies one.

What

The daemon lock can be read, acquired and deleted through the v5 storage backend rather than a file, when a backend handle is passed in.

Details
  • the read, acquire and delete helpers and the status query all take an optional storage backend argument
  • the lock is a daemon-lock state entry written with an ifAbsent precondition, with dedicated error messages and a size cap that clears a too-large lock
  • read failures with ENXIO, EFBIG, ELOOP or ENAMETOOLONG delete the lock rather than throwing
  • the status command and the version-mismatch check now pass the handle through; whether a backend is actually supplied depends on the caller
  • none of the v5 lock strings exist in the previous build

submit_feedbackdraft_idattach_transcript
What

The submit_feedback control request can now point at a draft saved on disk, so the upload matches the consent form the user actually saw.

Details
  • the request schema gained draft_id, type, title, area and attach_transcript
  • with a draft id the handler reads the stored draft from ~/.claude/feedback/drafts/, rebuilds the description, bundles that draft's own transcript according to attach_transcript (default true), and deletes the draft on success
  • caller-supplied fields override the stored draft
  • a new feedback_draft_queued system message carrying draft_id, draft_type, title and a details preview is emitted when Claude queues a draft locally, and it was added to the system subtypes that are not treated as ordinary transcript output
  • the feedback surface itself is behind Je("tengu_juniper_relay", !1), which falls back to false absent a remote value

allow_plugin_skill_search
What

A scope-expansion path can refresh the claude.ai token to obtain a new user:plugins scope before the plugin search route is called, but search itself is still behind an existing policy gate.

Details
  • The claude.ai project scope list gained user:plugins.
  • The expansion logs under [plugins-scope] and reports plugins_scope_expansion outcomes including save_failed and expand_failed, the latter with detail "refresh succeeded but user:plugins not granted".
  • It bails out for custom OAuth clients, non-claude.ai providers, and when nonessential traffic is disabled.

Running /code-review without a level now reuses the level you last typed explicitly, and the command is no longer something Claude can invoke on its own unless a new gate is on.

Details
  • disableModelInvocation is now a function evaluated lazily; it returns true unless the gate tengu_dazzling_floyd is on, and the fallback is false, so by default the model cannot invoke /code-review itself
  • command registration treats a function-valued disableModelInvocation as true when serializing and installs it as a getter
  • two new slash-command hooks were added and allowlisted as declared fields: getDefaultEffort (returns an effort value plus a user-facing notice) and onUserTypedArgs (records the level you typed)
  • the last explicitly typed level is persisted to global config as codeReviewLastEffort
  • the dispatch path, including stacked commands, calls onUserTypedArgs, and when no explicit level is given it pushes the default-effort notice into the transcript as a notice message, in interactive sessions only

CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENTmodelOverridesDISABLE_AUTO_COMPACTDISABLE_COMPACT/context
What

With auto-compact on and a model name Claude Code does not know, the session is now kept within an assumed token budget instead of waiting for the API to report a window.

Details
  • the context-window resolver gained a new result source: "unknown-model", which pins the window to the computed maximum
  • a notice names the model, states the assumed token budget, and points at the modelOverrides setting or an update
  • model overrides are consulted first via a new helper reading eo().modelOverrides, so an overridden model is not treated as unknown
  • /context and /config style output now label the figure "default for an unrecognized model", and "default for this model" for model-default sources
  • set CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1 to restore the previous wait-for-the-API behaviour; enforcement is also skipped when auto-compact is off via DISABLE_AUTO_COMPACT or DISABLE_COMPACT
Evidence

CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1 restores the previous wait-for-the-API behavior., CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT, is not a model this version of Claude Code recognizes, so auto-compact will keep this session within

The model shortcut now actually opens the model picker in cloud sessions instead of just advising you.

/model
What

The model shortcut now does something in cloud sessions rather than only printing advice.

Details
  • Previously the shortcut always showed the feedback notification "Use /model to change the model in cloud sessions".
  • That notification is now shown only when the UI is busy: a dialog is open, the cursor is not at the prompt, or a switch is already in flight.
  • Otherwise the shortcut invokes the model command directly, guarded by a re-entrancy ref.

New hidden CLI flag --resume-drops-turn#

A hidden flag lets you declare which turn a truncating resume is meant to discard.

--resume-drops-turn--resume-session-at--resume-p
What

A hidden print-mode option that pairs with --resume-session-at, letting you declare the prompt uuid of the turn a truncating resume intends to discard.

Details
  • the resume is refused if the discarded range contains anything not attributable to the declared turn
  • using it without --resume-session-at is a hard error
  • rejections are reported with a fixed prefix
Usage
claude -p --resume --resume-session-at <chain-entry-uuid> --resume-drops-turn <prompt-uuid>

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.223: not a boolean we can read

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

The /recap command, the away-summary feature and the "Session recap" entry in the settings menu all dropped their tengu_sedge_lantern check, so they are reachable in this build without the experiment.

Details
  • Removed from three places: isEnabled on the /recap command, the away-summary enablement check, and the settings menu item.
  • Away summary still requires CLAUDE_CODE_ENABLE_AWAY_SUMMARY or the awaySummaryEnabled setting.

Details
  • Applies to /teleport, /session and /remote-control among others; for example /teleport returns text explaining that it pulls a cloud session into a terminal on your own machine, so it cannot run from inside this session, and gives claude --teleport <id>.
  • The tailored text requires a known remote session id from CLAUDE_CODE_REMOTE_SESSION_ID.

Credential read errors are classified by errno#

A temporary failure reading your credentials no longer looks like being logged out.

What

A failed credentials read is now distinguished from an empty credential store, so a transient read failure no longer causes token refresh to proceed as if you had no credentials.

Details
  • ENOENT, EISDIR and ENOTDIR return null, meaning no credentials

A truncating resume can now declare which turn it intends to discard, and is refused if the discarded range contains anything that does not belong to that turn.

Details
  • registered as --resume-drops-turn <message id> with help text "declare the prompt uuid of the turn the truncating resume intends to discard; the resume is refused if the discarded range contains anything not attributable to that turn"
  • refusal triggers on absorbed queued messages, compaction summaries, externally-sourced entries and task notifications; the message names a per-entry reason such as a range containing a compaction summary or a non-furniture attachment

  • frames are validated for a string key, string text and a known priority; malformed frames are dropped with a debug line
  • normalisation prefixes the key with remote:, collapses text to a single line, downgrades immediate priority to high and clamps the timeout
  • an older remote notification is evicted when the remote quota is full

Peer Messaging not in their notes

Peer messages are admitted through a new loop and abuse guard#

Incoming peer messages now pass rate, duplicate and loop checks before queuing, with drops shown to you.

Feature flag
tengu_harbor_kite_limits Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.223: not a boolean we can read

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.223. It isn't a statement about your account. What a flag value here can and cannot tell you

tengu_harbor_kite_limits
What

Incoming peer messages are checked before they reach the queue, so a runaway relay chain or a flood from one sender is dropped rather than processed.

Details
  • checks are a per-sender token bucket, a duplicate-body window, a self-hop loop detector, a relay-chain length cap, and a cap on queued peer messages
  • built-in defaults: bucketCapacity 30, refillPerSecond 0.5, dedupWindowMs 30000, maxSelfHops 10, maxChainLength 28, maxTrackedSenders 256

The auto-react composer can now apply targeted find/replace edits to artifact source rather than regenerating the whole document.

Details
  • edits are exact-string, applied in order, subject to a byte budget and a per-edit uniqueness requirement
  • the full-rewrite form is kept only as an escape hatch for sweeping changes
  • one retry with feedback when a find string is not found or is ambiguous, and one re-prompt when the decision JSON is malformed

Details
  • handled alongside the existing peer, channel and observer kinds through routing, prefixing and mid-turn handling
  • content is prefixed with the literal marker [MESSAGE FROM NON-USER SOURCE - NOT USER INPUT], added only when not already present

Projects scope expansion explains custom OAuth clients and save failures#

Expanding Projects permissions now tells you up front when it cannot proceed or could not save credentials.

What

Expanding scopes for Projects now refuses up front in cases it cannot handle and gives a distinct reason when the refreshed credentials could not be stored.

Details
  • a login using a custom OAuth client is refused before any request is made
  • a save_failed reason is reported when the server has already consumed the old credentials but the new ones could not be persisted
  • the refresh call is passed an abort signal and a projects_scope_expansion telemetry context

Details
  • The loading spinner is now the Suspense fallback rather than a manually rendered state.
  • Minimum height of the dialog was increased.
  • A confirm:no handler was registered so dismissal is reported.

IDE diagnostics attachments are validated before replay#

Editor diagnostics restored from saved sessions are checked for junk before being shown, so bad data can't garble your screen.

Diagnostics restored from a replayed attachment are now sanitized, so a malformed or crafted payload cannot reach the renderer.

Details
  • a new sanitizeDiagnosticFiles static drops non-array payloads and logs once per payload shape
  • file entries are dropped unless they have a string uri and an array of diagnostics; individual diagnostics are dropped unless they have a string message and numeric range start line and character
  • missing ranges are normalized, and the count of dropped files and diagnostics is logged once per payload
  • severity strings map through an explicit table (error, warning, info, information, hint), and getSeveritySymbol now uses Object.hasOwn and rejects non-string input, so a crafted severity cannot reach an inherited property

Bash [[ ]] conditionals: two new bail-outs for shell-lexer divergence#

Tricky bash double-bracket conditions are now treated as too complex instead of being misread.

What

The command parser now refuses to parse two [[ ]] shapes where zsh's cond-lexer disagrees with the parser, classifying them as too-complex differential cases instead.

Details
  • a [[ ]] pattern leaf containing && now bails out, because zsh splits the word there
  • a pattern leaf containing a potential standalone ]] closer also bails out, because zsh closes the conditional differently

Storage Backend

Daemon lock and auto-update lock gained storage-backend implementations#

Lock files that stop two sessions clashing can now live in a storage backend instead of on disk.

What

Acquiring, reading, replacing and releasing the daemon lock, plus the auto-updater's stale-lock detection and release, now each have a storage-key branch alongside the original file-based logic.

Details
  • acquisition uses an ifAbsent write with a umask-derived mode; staleness is decided from stat; release deletes the key
  • lock-contention telemetry codes trigger a re-read and one retry before the acquisition fails
  • the file-based path is still present and is what runs without a backend

Transcript existence checks and project-directory discovery can use record streams#

Checking whether a past transcript has content can now run over streamed records instead of files.

What

The probe that decides whether a transcript has real content, and the sibling project-directory lookup, gained backend implementations built on record streams and entry listing.

Details
  • the probe pages through readRecords looking for "type":"user" and "type":"assistant" markers
  • it falls back to statStream before answering 'none', and returns 'unknown' when records were truncated or the scan did not converge

git_remote_url added to the internal telemetry event schema#

A git remote URL field is wired through internal analytics but nothing fills it in yet.

A git_remote_url column is plumbed end to end in the internal event schema with no producer setting it in this build.

What

The internal analytics event message gained a git remote URL field, plumbed end to end but with no producer found in this build.

Details
  • git_remote_url is a string field wired through the default, encode, decode, toJSON and fromPartial paths of the event proto.
  • When building ClaudeCodeInternalEvent it is promoted out of the event's _PROTO_git_remote_url extra into a first-class column, alongside the existing skill, plugin, marketplace and head_sha fields.

File downloads can now come from a server-supplied host, but only for unauthenticated requests.

What

The internal HTTP helper can take a base URL from the request itself, which the filestore staging path now uses to fetch from a server-supplied host.

Details
  • the override returns a request-supplied baseUrl only when the request is unauthenticated (auth: "none") and the host is not "frame"

Published verbatim by Anthropic for v2.1.223. Text is unmodified from the upstream changelog. Everything else on this page came out of the bundle instead, which is why the two lists don't match.

  • Added owner wildcard entries ("owner/*") to the strictKnownMarketplaces and blockedMarketplaces managed settings for allowing or blocking all marketplace repos under a GitHub org
  • Added a warning when workflow agents, forked skills, slash commands, or resumed background agents' requested subagent model is restricted and the parent model runs instead
  • Added a /teleport hint in cloud sessions showing how to continue locally with claude --teleport <session id>
  • Fixed a Bash permission bypass where a crafted command could hide parts of itself from permission checks
  • Fixed permission prompts so commands padded with tabs or invisible Unicode can no longer hide part of the command from the approval dialog
  • Fixed workflow scripts being able to use dynamic import() to run code outside the workflow sandbox
  • Fixed a permission gap where an agent definition's bypassPermissions mode ignored the org bypass-permissions disable policy
  • Fixed resuming a session after a mid-session /cd coming back empty
  • Fixed gateway model discovery hiding Claude models registered under provider-prefixed IDs such as vertex_ai/claude- or bedrock/anthropic.claude-
  • Fixed modelOverrides keys that aren't Anthropic model IDs being treated as the session's canonical model ID; unknown keys are now ignored as documented
  • Fixed managed settings: server-delivered settings no longer disable the env block of a machine-local managed-settings.json or MDM profile; admin env now merges per key
  • Fixed sandboxed commands failing to start on Linux when sandbox.filesystem.denyWrite covers the working directory
  • Fixed forked background agents getting stuck "already resuming" for the rest of the session when rebuilding the fork's parent prompt failed during resume
  • Fixed a resumed session failing every turn, or leaving the interactive app on an unresponsive error screen, when its history held a malformed diagnostics attachment
  • Fixed a rare hang when parsing unusual git push output
  • Changed CLAUDE_CODE_DISABLE_1M_CONTEXT to hold every Claude model with a native 1M window to 200K via auto-compaction, not just a fixed list; a startup warning now appears when auto-compaction isn't holding the session to 200K
  • Changed auto-compact to keep sessions on unrecognized model IDs within the assumed context window instead of letting them grow past it; set CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1 to restore the previous behavior
  • Changed /review to be an alias of /code-review, which reviews the current diff or a PR (/code-review <level> <pr#>); use /code-review ultra for a deep cloud review
  • Changed /code-review with no effort level to reuse the level you typed last; type a level like /code-review high to change it
