Captured: 2026-05-10T16:27:28.323Z

- Added automatic skill hot-reload - skills created or modified in `~/.claude/skills` or `.claude/skills` are now immediately available without restarting the session

- Changed Shift+Enter to work out of the box in iTerm2, WezTerm, Ghostty, and Kitty without modifying terminal configs
- Added `respectGitignore` support in `settings.json` for per-project control over @-mention file picker behavior

- Fixed pasted content being lost when replaying prompts from history using up arrow or Ctrl+R search
- Fixed Esc key with queued prompts to only move them to input without canceling the running task
- Reduced permission prompts for complex bash commands
- Fixed command search to prioritize exact and prefix matches on command names over fuzzy matches in descriptions

- Added wildcard pattern matching for Bash tool permissions using `*` at any position in rules (e.g., `Bash(npm *)`, `Bash(* install)`, `Bash(git * main)`)
- Added unified Ctrl+B backgrounding for both bash commands and agents - pressing Ctrl+B now backgrounds all running foreground tasks simultaneously
- Added support for MCP `list_changed` notifications, allowing MCP servers to dynamically update their available tools, prompts, and resources without requiring reconnection

- Added `CLAUDE_CODE_FILE_READ_MAX_OUTPUT_TOKENS` environment variable to override the default file read token limit
- Added support for `once: true` config for hooks
- Added support for YAML-style lists in frontmatter `allowed-tools` field for cleaner skill declarations

- Added filepath to full output in background bash task details dialog
- Added Skills as a separate category in the context visualization
- Fixed OAuth token refresh not triggering when server reports token expired but local expiration check disagrees
- Fixed session persistence getting stuck after transient server errors by recovering from 409 conflicts when the entry was actually stored
- Fixed session resume failures caused by orphaned tool results during concurrent tool execution
- Fixed a race condition where stale OAuth tokens could be read from the keychain cache during concurrent token refresh attempts
- Fixed AWS Bedrock subagents not inheriting EU/APAC cross-region inference model configuration, causing 403 errors when IAM permissions are scoped to specific regions
- Fixed API context overflow when background tasks produce large output by truncating to 30K chars with file path reference
- Fixed a hang when reading FIFO files by skipping symlink resolution for special file types
- Fixed terminal keyboard mode not being reset on exit in Ghostty, iTerm2, Kitty, and WezTerm
- Fixed Alt+B and Alt+F (word navigation) not working in iTerm2, Ghostty, Kitty, and WezTerm
- Fixed `${CLAUDE_PLUGIN_ROOT}` not being substituted in plugin `allowed-tools` frontmatter, which caused tools to incorrectly require approval
- Fixed files created by the Write tool using hardcoded 0o600 permissions instead of respecting the system umask
- Fixed commands with `$()` command substitution failing with parse errors
- Fixed multi-line bash commands with backslash continuations being incorrectly split and flagged for permissions
- Fixed bash command prefix extraction to correctly identify subcommands after global options (e.g., `git -C /path log` now correctly matches `Bash(git log:*)` rules)
- Fixed slash commands passed as CLI arguments (e.g., `claude /context`) not being executed properly
- Fixed pressing Enter after Tab-completing a slash command selecting a different command instead of submitting the completed one
- Fixed slash command argument hint flickering and inconsistent display when typing commands with arguments
- Fixed Claude sometimes redundantly invoking the Skill tool when running slash commands directly

- Fixed subagents sometimes not inheriting the parent's model by default

- Fixed Bash read commands (like `ls` and `cat`) not being counted in collapsed read/search groups, causing groups to incorrectly show "Read 0 files"
- Fixed spinner token counter to properly accumulate tokens from subagents during execution
- Fixed memory leak in git diff parsing where sliced strings retained large parent strings

- Improved subagents (Task tool) to continue working after permission denial, allowing them to try alternative approaches
- Improved skills to show progress while executing, displaying tool uses as they happen
- Improved skills from `/skills/` directories to be visible in the slash command menu by default (opt-out with `user-invocable: false` in frontmatter)
