v2.0.0 — Universal core, cross-harness gating, Cowork toggle

v1 gated skills for Claude Code only, by hiding descriptions behind domain
gate files. v2 keeps that mechanism but rebuilds it as a harness-neutral
CLI + MCP server (mo), so the same registry and gates can drive Claude
Code, Antigravity (AGY/Gemini), Cursor, Windsurf, or any MCP-capable agent —
not just one client.

Universal core

• New bin/mo.ts CLI and MCP stdio server backed by a shared registry,
  independent of any one harness's plugin format.
• claude-setup writes a self-contained, plug-and-play Claude Code plugin
  (gate skills + a SessionStart hook driven by mo).
• agy-setup generates the equivalent gate skills for Antigravity
  (master-of-design, master-of-dev, …), with cross-harness skill access
  so a skill installed for one harness is still listed for the other.
• Gate files now render per source (gates/<source>/<gate>.txt), so each
  harness only ever sees skills it can actually run.

Real dormancy, not just hidden descriptions

• mo park / mo unpark / mo unparked move raw skills between
  ~/.claude/skills/ and a skills-library/, so an always-on skill can
  actually become dormant instead of just having its description tucked
  behind a gate.
• mo doctor catches dead MCP binaries, disabled plugins backing a gated
  skill, and other install-time breakage — with a one-line fix suggestion
  each.
• mo cowork [list|on|off] [domain] (this release) toggles the ~17
  account-synced Cowork skill packs (figma, design, data, marketing,
  engineering, product-management, productivity, pdf-viewer,
  cowork-plugin-management, plus a few document skills) that Claude Code
  accounts with Cowork mirror onto disk. These have no marketplace entry
  and physically moving/deleting them doesn't work — the account sync
  re-creates them mid-session — but claude plugin enable/disable <domain>@synced does, and that's what this command drives. Cowork's own
  sync and collaboration features are untouched; only whether Claude Code
  loads the pack into its system prompt is toggled.

Reporting & classification

• mo full / mo status / check-skills-all give a token-safe compact
  inventory by default, with a --raw guardrail for the full text dump.
• mo classify takes --desc, --cluster, --domain for filing
  unclassified components straight from the scanner's guess.
• check-skill (brief) and check-skill-all (full) give AGY sessions the
  same proactive token-waste diagnosis Claude Code gets.
• Token-savings math is now scoped to each report's own source, so a
  Claude-only session isn't diluted by Gemini-only components in the
  denominator.

Net effect

On the maintainer's own machine, going from a fresh v1 baseline to this
release's mo cowork off state: 87% token reduction (37,598 → 4,951 tok
per session), matching v1-era savings despite covering roughly 5x more
components (625 vs. 129) across more harnesses.
