Shkarko Claude Code 2.1.117

- Forked subagents can now be enabled on external builds by setting CLAUDE_CODE_FORK_SUBAGENT=1
- Agent frontmatter mcpServers are now loaded for main-thread agent sessions via --agent
- Improved /model: selections now persist across restarts even when the project pins a different model, and the startup header shows when the active model comes from a project or managed-settings pin
- The /resume command now offers to summarize stale, large sessions before re-reading them, matching the existing --resume behavior
- Faster startup when both local and claude.ai MCP servers are configured (concurrent connect now default)
- plugin install on an already-installed plugin now installs any missing dependencies instead of stopping at "already installed"
- Plugin dependency errors now say "not installed" with an install hint, and claude plugin marketplace add now auto-resolves missing dependencies from configured marketplaces
- Managed-settings blockedMarketplaces and strictKnownMarketplaces are now enforced on plugin install, update, refresh, and autoupdate
- Advisor Tool (experimental): dialog now carries an "experimental" label, learn-more link, and startup notification when enabled; sessions no longer get stuck with "Advisor tool result content could not be processed" errors on every prompt and /compact
- The cleanupPeriodDays retention sweep now also covers ~/.claude/tasks/, ~/.claude/shell-snapshots/, and ~/.claude/backups/
- OpenTelemetry: user_prompt events now include command_name and command_source for slash commands; cost.usage, token.usage, api_request, and api_error now include an effort attribute when the model supports effort levels. Custom/MCP command names are redacted unless OTEL_LOG_TOOL_DETAILS=1 is set
- Native builds on macOS and Linux: the Glob and Grep tools are replaced by embedded bfs and ugrep available through the Bash tool — faster searches without a separate tool round-trip (Windows and npm-installed builds unchanged)
- Windows: cached where.exe executable lookups per process for faster subprocess launches
- Default effort for Pro/Max subscribers on Opus 4.6 and Sonnet 4.6 is now high (was medium)
- Fixed Plain-CLI OAuth sessions dying with "Please run /login" when the access token expires mid-session — the token is now refreshed reactively on 401
- Fixed WebFetch hanging on very large HTML pages by truncating input before HTML-to-markdown conversion
- Fixed a crash when a proxy returns HTTP 204 No Content — now surfaces a clear error instead of a TypeError
- Fixed /login having no effect when launched with CLAUDE_CODE_OAUTH_TOKEN env var and that token expires
- Fixed prompt-input undo (Ctrl+_) doing nothing immediately after typing, and skipping a state on each undo step
- Fixed NO_PROXY not being respected for remote API requests when running under Bun
- Fixed rare spurious escape/return triggers when key names arrive as coalesced text over slow connections
- Fixed SDK reload_plugins reconnecting all user MCP servers serially
- Fixed Bedrock application-inference-profile requests failing with 400 when backed by Opus 4.7 with thinking disabled
- Fixed MCP elicitation/create requests auto-cancelling in print/SDK mode when the server finishes connecting mid-turn
- Fixed subagents running a different model than the main agent incorrectly flagging file reads with a malware warning
- Fixed idle re-render loop when background tasks are present, reducing memory growth on Linux
- [VSCode] Fixed "Manage Plugins" panel breaking when multiple large marketplaces are configured
- Fixed Opus 4.7 sessions showing inflated /context percentages and autocompacting too early — Claude Code was computing against a 200K context window instead of Opus 4.7's native 1M
