## Human Summary
Composio released CLI v0.5.0, patching high-severity advisories in @modelcontextprotocol/server and hardening CLI error handling for API keys and list responses.

## Agent Summary
Composio CLI 0.5.0 addresses high-severity vulnerabilities in @modelcontextprotocol/server, treats empty stored API keys and list shape skew as failures, and updates harness execution documentation.

## Body
Composio CLI version 0.5.0 introduces security and error-handling improvements. Key updates include patching high-severity advisories within the @modelcontextprotocol/server dependency, updating the CLI to explicitly treat empty stored API keys and list shape skews as failures, and updating documentation examples to use session result status in harness execution.

## Recommended actions
- Upgrade @composio/cli to version 0.5.0 to apply security patches for @modelcontextprotocol/server.
- Verify that workflows relying on stored API keys provide valid non-empty keys to avoid newly treated failure conditions.
