+### Changed
+
+- PyPI metadata: expanded keywords to multi-word search phrases for better
+  Elasticsearch ranking (`"llm safety"`, `"budget enforcement"`, `"agent guardrails"`,
+  `"langchain safety"`, `"openai guardrails"`, `"ai automation"`, and 35 more).
+- README: added keyword-rich opening paragraph for Google indexing of the PyPI page.
+- `pyproject.toml`: bumped Development Status to `5 - Production/Stable`,
+  added `Topic :: Security` classifier, `Operating System :: OS Independent`.

 Formal safety for AI agents — enforced at execution, not in the prompt.
 
+**ClampAI** is a Python safety framework for LLM agents and AI automation — budget enforcement, safety guardrails, invariant checking, and rate limiting at the execution layer. Works with LangChain, LangGraph, OpenAI, Anthropic, OpenClaw, AutoGen, CrewAI, and FastAPI. Zero runtime dependencies.
