Claude Code 2.1.74

Enhanced `/context` command with actionable optimization suggestions — identifies context-heavy tools, memory bloat, and capacity warnings with specific remediation tips. This makes memory/capacity management observable and prescriptive rather than opaque.

New primitives

/context (enhanced)command

Identifies context-heavy tools, memory bloat, and capacity warnings with specific optimization tips

Added actionable suggestions to `/context` command — identifies context-heavy tools, memory bloat, and capacity warnings with specific optimization tips
autoMemoryDirectorysetting

Configure a custom directory for auto-memory storage

Added `autoMemoryDirectory` setting to configure a custom directory for auto-memory storage
CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MSenv-var

Configure timeout duration for `SessionEnd` hooks on exit

Fixed `SessionEnd` hooks being killed after 1.5 s on exit regardless of `hook.timeout` — now configurable via `CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS`

Workflow recipes

Configurable Memory Audit & Optimization Loop
/context (enhanced with actionable suggestions) + autoMemoryDirectory + CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS

Long-lived agents can now observe memory state, configure where it persists, and control cleanup timing—unlocking automated memory governance for sustained workflows.

An agent or autonomous session could periodically invoke /context to sample memory bloat and context saturation, apply /context suggestions to trim tools or memory, reconfigure autoMemoryDirectory to offload to external storage if needed, and use SessionEnd hooks with extended timeout (via env-var) to ensure graceful cleanup on multi-hour runs. This closes the feedback loop on memory management—from opacity to prescribed optimization to configurable persistence.

Managed Policy Compliance & Model Flexibility
Fixed managed policy ask rules + Fixed full model IDs in agent configs

Security policy enforcement and model specification are now consistent across agent frontmatter, JSON config, and CLI—enabling reliable multi-agent teams under managed settings.

An orchestration layer can now safely deploy agents with explicit model pinning (using full IDs like claude-opus-4-5) and trust that managed policy rules (e.g., ask gates) will not be bypassed by user allow rules. This enables guardrailed multi-agent workflows where each agent has a declared model and security policy is enforced top-down rather than locally overridden. Teams moving to managed instances can migrate agents without rewriting config.

Agentic relevance

The `autoMemoryDirectory` setting and enhanced `/context` command enable agents to audit and configure memory storage at runtime, critical for long-lived workflows. The env-var timeout control improves exit-time hook predictability. Hardening fixes around model IDs, OAuth, and managed policies strengthen agent reliability in multi-tenant and integration scenarios.

Hardening & fixes (14)

  • Fixed memory leak where streaming API response buffers were not released when the generator was terminated early, causing unbounded RSS growth on the Node.js/npm code path
  • Fixed managed policy `ask` rules being bypassed by user `allow` rules or skill `allowed-tools`
  • Fixed full model IDs (e.g., `claude-opus-4-5`) being silently ignored in agent frontmatter `model:` field and `--agents` JSON config — agents now accept the same model values as `--model`
  • Fixed MCP OAuth authentication hanging when the callback port is already in use
  • Fixed MCP OAuth refresh never prompting for re-auth after the refresh token expires, for OAuth servers that return errors with HTTP 200 (e.g. Slack)
  • Fixed voice mode silently failing on the macOS native binary for users whose terminal had never been granted microphone permission — the binary now includes the `audio-input` entitlement so macOS prompts correctly
  • Fixed `/plugin install` failing inside the REPL for marketplace plugins with local sources
  • Fixed marketplace update not syncing git submodules — plugin sources in submodules no longer break after update
  • Fixed unknown slash commands with arguments silently dropping input — now shows your input as a warning
  • Fixed Hebrew, Arabic, and other RTL text not rendering correctly in Windows Terminal, conhost, and VS Code integrated terminal
  • Fixed LSP servers not working on Windows due to malformed file URIs
  • Changed `--plugin-dir` so local dev copies now override installed marketplace plugins with the same name (unless that plugin is force-enabled by managed settings)
  • [VSCode] Fixed delete button not working for Untitled sessions
  • [VSCode] Improved scroll wheel responsiveness in the integrated terminal with terminal-aware acceleration
