Memory Consolidation (DreamTask)#

What

A new background task type called "DreamTask" that automatically consolidates memory by reviewing past sessions. It runs in the background, reviews recent sessions since the last consolidation, and updates memory files with new learnings.

Details
  • Fires automatically based on configurable thresholds (default: 24 hours since last consolidation, minimum 5 sessions)
  • Shows a "Memory consolidation" UI panel with real-time status: sessions reviewing, files touched, and running/completed state
  • Can be stopped with x during execution, which rolls back the lock
  • Tracks the tengu_auto_dream_fired and tengu_auto_dream_failed analytics events
  • Restricted to read-only Bash commands (ls, find, grep, cat, stat, wc, head, tail) during execution
Evidence

Web Setup Command#

Feature flag
tengu_cobalt_lantern 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.

This account: on · anonymous baseline: on · compiled default in v2.1.79: no gate table built for this version

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 v2.1.79. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A new /web-setup command that connects Claude Code to Claude on the web by importing your GitHub credentials, enabling cloud-based sessions.

Details
  • Checks your Claude login status and GitHub CLI authentication
  • Prompts for confirmation before uploading your GitHub token
  • Creates a default cloud environment provider automatically
  • Gated behind the tengu_cobalt_lantern feature flag (gradual rollout)
  • Shows appropriate error messages for various failure cases: not signed in, GitHub token rejected, server errors, network issues
Evidence

Web setup flow (search for "Connect Claude on the web to GitHub?" and "web-setup")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Subprocess Environment Scrubbing#

What

A new CLAUDE_CODE_SUBPROCESS_ENV_SCRUB environment variable that, when enabled, strips sensitive credentials from the environment passed to subprocesses (like Bash tool invocations).

Usage
CLAUDE_CODE_SUBPROCESS_ENV_SCRUB=1 claude
Details
  • Removes API keys, OAuth tokens, and other secrets from subprocess environments
  • Scrubbed variables include: ANTHROPIC_API_KEY, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GOOGLE_APPLICATION_CREDENTIALS, AZURE_CLIENT_SECRET, GitHub Actions tokens, and more
  • Also scrubs INPUT_ prefixed variants of all listed variables
Evidence

Environment scrubbing for subprocess execution (search for "CLAUDE_CODE_SUBPROCESS_ENV_SCRUB")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Memory Verification Instructions#

What

New system prompt instructions that teach the model to verify memories against current code before recommending from them. Memories about file paths, functions, or flags may be stale—the model now greps or checks files before acting on recalled information.

Details
  • Added a "Before recommending from memory" section to the memory system prompt
  • Instructs the model: "If the memory names a file path: check the file exists", "If the memory names a function or flag: grep for it"
  • Emphasizes that '"The memory says X exists" is not the same as "X exists now."'
Evidence

Memory verification guardrails (search for "Before recommending from memory" and "The memory says X exists")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Stdin Timeout Warning#

What

When piping input to Claude Code from a slow command, a warning is now shown after 3 seconds if no stdin data has been received, helping users diagnose piping issues.

Details
  • Warns: "Warning: no stdin data received in 3s, proceeding without it. If piping from a slow command, redirect stdin explicitly: < /dev/null to skip, or wait longer."
  • Uses a configurable timeout to detect stalled stdin
Evidence

Stdin timeout detection (search for "no stdin data received in 3s")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Mobile App Summary Labels#

What

After tool use, the model is now prompted to generate a short summary label (git-commit-subject style, ~30 characters) suitable for display as a single-line row in a mobile app.

Details
  • Replaces the previous generic "Provide a brief summary of what was accomplished" prompt
  • New labels are past-tense, concise, and drop articles/connectors (e.g., "Searched in auth/", "Fixed NPE in UserService", "Created signup endpoint")
Evidence

Mobile-optimized summary labels (search for "Write a short summary label")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Related

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.

Slow Hook and Permission Logging#

Added performance logging that warns when PreToolUse hooks, PostToolUse hooks, or permission decisions take an unusually long time. This helps diagnose slow hook configurations that degrade responsiveness.

Evidence

Performance diagnostics for hooks (search for "Slow PreToolUse hooks:", "Slow PostToolUse hooks:", and "Slow permission decision:")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Tool Input Coercion for Numeric Parameters#

Bash tool's timeout parameter and Grep tool's numeric parameters (-A, -B, -C, context, head_limit, offset) now accept string representations of numbers and coerce them to numeric types. This prevents errors when the model passes "5000" instead of 5000.

Evidence

Numeric string coercion wrapper (search for "oR(" in the Grep and Bash tool schema definitions)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

PDF Reading Error Message Improvement#

The error message for unsupported full-PDF reading has been updated from "only supported with the Anthropic API" to "not supported with this model. Use a newer model (Sonnet 3.5 v2 or later)". This gives users clearer guidance on which models support the feature.

Evidence

Model-specific PDF error (search for "Reading full PDFs is not supported with this model")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

User Message Hover Styling#

All themes now include a userMessageBackgroundHover color, providing visual feedback when hovering over user messages in the transcript.

Dimmed Nested Output Indicators#

The ⎿ prefix indicators in tool output and stderr rendering are now displayed with dimmed color (dimColor: true), improving visual hierarchy and reducing clutter in dense output.

Evidence

Dimmed output prefix styling (search for "dimColor" near "⎿")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Bash Command Formatting Prefix#

Bash commands displayed in the transcript now include a $ prefix, making them visually distinguishable as shell commands.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

SIGINT Handling in Print Mode#

SIGINT (Ctrl+C) signals are now ignored when running in --print (-p) mode, preventing accidental termination during non-interactive pipeline usage.

Evidence

Print mode signal handling (search for 'process.argv.includes("-p")')

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Cross-Marketplace Plugin Dependencies#

The plugin system now supports allowCrossMarketplaceDependenciesOn in marketplace configuration, enabling plugins from one marketplace to declare dependencies on plugins from specified other marketplaces.

Evidence

Enhanced dependency schema (search for "@\\^[^@]*$")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Event Batch Size Limiting#

The event uploader now respects a maxBatchBytes limit (10 MB) in addition to maxBatchSize, preventing oversized event batches that could fail server-side.

Read once, for one account on one subscription tier, against v2.1.79. It isn't a statement about your account. What a flag value here can and cannot tell you

What

A new --claudeai flag appears alongside a billing selection flow that lets users choose between "Use Anthropic Console (API usage billing)" and "Use Claude subscription (default)".

Status

Feature-flagged — the web-setup flow it ties into is gated behind tengu_cobalt_lantern (defaults to false).

Details
  • Error message added: "Error: --console and --claudeai cannot be used together"
  • Suggests this is infrastructure for a Claude web/subscription billing path alternative to API key billing

Notesopen

#

  • The JWT library bundled within Claude Code has been replaced: the old multi-file jwa/jws/Buffer-based implementation was removed in favor of a leaner inline version with improved error handling for missing HMAC secrets.
  • The claude-developer-platform skill content has been significantly updated with new model references (Opus 4.6, Sonnet 4.6), adaptive thinking guidance, compaction documentation, and multi-language SDK support information including Go, Ruby, C#, and PHP.
