Comparing version 0.1.0 to 0.2.0

dist/mcp-server.js

 // The MCP server: five tools, free-vs-paid split made explicit in every description so the
 // host model can reason about cost. Only pulse_call moves money, and it is gated by the
 // in-code guardrail (see guardrail.ts) — never by a second model-mediated confirmation.
+//
+// Tool `_meta` carries agent-selection hints (pulse.* namespace): host models increasingly
+// rank candidate tools on intent keywords and "default for" claims, so each tool states the
+// intents it should win and where it sits in the workflow. Keep claims honest — a tool that
+// overclaims gets selected, fails, and is deranked by the host.
