staleness flags

file	claim	reality	severity
docs/tips/fast-mode.md	fast mode keeps you on opus. it does not switch to a cheaper or smaller model.	v2.1.158 introduces auto mode on Bedrock/Vertex/Foundry for Opus 4.7 and 4.8, which may change model selection behavior depending on platform and settings	medium
docs/tips/plugins.md	plugins require manual installation via /plugin marketplace add	v2.1.157 now auto-loads plugins from .claude/skills directories without marketplace required, and added claude plugin init <name> scaffolding	high
docs/hooks.md	hooks are the only enforcement mechanism for behavior	v2.1.157 allows plugins in .claude/skills to include hooks, making the plugin-hook relationship bidirectional	low
docs/tips/subagents.md	EnterWorktree is a static action within a worktree	v2.1.157 added ability to switch between Claude-managed worktrees mid-session with EnterWorktree	medium
docs/worktrees.md	worktrees managed by Claude require manual cleanup	v2.1.157 now leaves Claude-managed worktrees unlocked so git worktree remove/prune can clean them up automatically	low
