Claude Code v2.1.140 — Agent subagent_type matching, /loop wakeup fix

What's new in Claude Code v2.1.140

Four quality-of-life changes that take real paper cuts out of advanced workflows: subagent_type matching becomes case- and separator-insensitive on the Agent tool, /loop stops scheduling redundant wakeups for self-notifying tasks, plugin authors now get a warning when a plugin.json key silently shadows a default component folder, and /goal reports cleanly instead of hanging when hooks are disabled.

Agent tool subagent_type matching is now case- and separator-insensitive

Why: Specifying subagent_type had to match the exact slug; common variants like "Code Reviewer" failed against code-reviewer for no good reason.

What: The Agent tool now resolves subagent_type case- and separator-insensitively, so "Code Reviewer", "code reviewer", and "code-reviewer" all match.

How: No action — slugs you'd intuitively write now just work.

/loop no longer schedules redundant wakeups for self-notifying tasks

Why: /loop was scheduling polling wakeups even when its watched task already notifies on completion, burning context and cache for no useful work.

What: /loop now skips redundant wakeups when the task it's watching emits its own completion signal.

How: No action — existing /loop invocations get cheaper automatically.

Plugins warn when default component folders are silently shadowed

Why: Setting a commands (or similar) key in plugin.json was silently disabling discovery of the default commands/ folder, leaving plugin authors confused why their components didn't appear.

What: Plugins now warn when a default folder is shadowed by an explicit plugin.json key. The warning shows up in /doctor, claude plugin list, and /plugin.

How: No action; check /doctor after upgrade if you suspect a plugin is missing components.

/goal reports clearly when hooks are disabled

Why: When disableAllHooks or allowManagedHooksOnly is set, /goal was silently hanging on an indicator that never resolved — looked like a broken command.

What: /goal now shows a clear "hooks are disabled" message instead of hanging.

How: No action — the failure mode is now diagnosable.
