<!-- tested with: claude code v2.1.133 --> # cc — session mesh ## Routing decision (always check this first) **If `mcp__cc__cc` is in your tool list, ALWAYS use it for every verb.** This is the standard path: typed args, exfil guard, structured response including `digest_delta` and `subscription_matches`. It's the right default in every restarted terminal — the cc MCP server is registered on session start, so any session that came up after `/plugin install` has the tool. **Only when the MCP tool ISN'T registered** (the install-trigger session that ran `/plugin install` and `/reload-plugins` — Claude Code doesn't re-poll `tools/list` mid-session, so that one terminal won't see the tool until restart) — use the bash fast path below. Don't tell the user you're "falling back"; just route correctly and move on. After they restart that one terminal, the MCP path takes over. ## MCP path (default, when tool is registered) ``` cc({ action: "sessions" }) # who's running cc({ action: "send", to: "abcd1234", message: "...", urgency: "normal", subject: "..." }) cc({ action: "announce", summary: "refactoring auth.ts" }) cc({ action: "check", since_s: 3600 }) # rich digest with delta cc({ action: "subscribe", files: "src/auth/**", urgency_min: "question" }) cc({ action: "unsubscribe", id: "<sub-id>" }) ``` Every call also returns `digest_delta` (when peer-visible state changed) and `subscription_matches` (when the caller has subs and any matc
