What probably matters to youSection of the release

/plugin stats and the relocated /skill-doctor are built but sit behind CLAUDE_CODE_LANTERN_PRISM, off by default.

What

The plugin UI has a new stats view showing skill usage and context costs, and /skill-doctor now redirects there.

Details
  • New "stats" view and a tab titled "Stats"; both /plugin stats and the marketplace argument parser route to it, with help line " /plugin stats - Show skill usage and context costs".
  • A notice tells users "/skill-doctor moved — skill usage and context costs now live in this Stats tab."
  • /skill-doctor is registered as two variants, an immediate local-jsx one that renders the view and the existing local one that produces plain text in non-interactive mode, both described as "Show which loaded skills are unused and costing context".
  • skill-doctor was added to the command log-level map as "info".
  • Gated on tengu_lantern_prism (fallback false) or the CLAUDE_CODE_LANTERN_PRISM env var; the skill-doctor registration now sits on the same gate as the Stats tab.
Evidence

/skill-doctor moved \u2014 skill usage and context costs now live in this Stats tab., skill usage and context costs now live in this Stats tab.

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

Flag reading moved The flag server now returns on for tengu_lantern_prism, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
