  • Simplified installation and usage instructions
  • Added accurate development status section

Results

  • All 91 tests in fluent-agent package now pass
  • Zero build warnings across all core packages
  • Clean compilation for fluent-core, fluent-engines, and fluent-agent
  • Accurate documentation that matches actual capabilities

Testing

# All tests pass
cargo test --package fluent-agent
# test result: ok. 91 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out

# Clean build with no warnings
cargo build --package fluent-agent
# Finished dev [unoptimized + debuginfo] target(s)

Walkthrough

This update introduces a comprehensive multi-layered enhancement to the Fluent CLI agentic platform. It adds new modules and implementation plans for advanced MCP transport (supporting Stdio, HTTP, WebSocket), workflow orchestration, security/sandboxing, and performance optimization. The changes include new public APIs, configuration structures, transport abstractions, workflow engines, security policy frameworks, connection pooling, multi-level caching, and documentation outlining phased implementation strategies.

Poem

🐇
New tunnels dug beneath the ground,
HTTP and WebSockets now abound!
Workflows weave and caches grow,
Security guards the streams that flow.
With plans and code, we leap ahead—
A rabbit’s dream, robustly spread!
