+
+Rust Coding Standards for Fluent CLI
+General Principles
+Safety and Reliability: Prioritize safe code. Avoid unsafe blocks unless absolutely necessary and justify their use with comments. Use Rust's ownership and borrowing system to prevent common errors.
+Error Handling: Never use .unwrap() or .expect() in production code. Always handle errors properly using Result and ? operator. Propagate errors up the call stack where appropriate, and provide meaningful error messages.
+Performance: Optimize for efficiency, especially in CLI tools where speed matters. Use efficient data structures and avoid unnecessary allocations.
+Modularity: Keep code modular. Each crate should have a single responsibility (e.g., fluent-core for utilities, fluent-engines for LLM integrations).
+Documentation: Every public function, struct, and module must have doc comments. Use /// for documentation and include examples where possible.
+Formatting and Style
+Rustfmt: All code must be formatted using rustfmt. Run cargo fmt before committing.
+Clippy: Enforce Clippy lints. Run cargo clippy --all -- -D warnings and fix all warnings.
+Naming Conventions:
+Use snake_case for variables, functions, and modules.
+Use CamelCase for types (structs, enums, traits).
+Use SCREAMING_SNAKE_CASE for constants.
+Avoid abbreviations unless they are standard (e.g., ctx for context).
+Line Length: Limit lines to 100 characters where possible.
+Imports: Group imports: standard library first, then third-party, then local. Use fully qualified paths for clarity in ambiguous cases.
+Code Structure
+Modules: Use modules to organize code logically. Each file should correspond to a module or a small set of related items.
+Traits and Impl: Define traits for interfaces and implement them for types. Favor composition over inheritance.
+Generics and Lifetimes: Use generics for type safety and flexibility. Annotate lifetimes explicitly when needed.
+Concurrency: Use std::sync or Tokio for async where appropriate. Ensure thread-safety in shared state.
+Specific to Fluent CLI
+CLI Parsing: Use Clap for argument parsing. Structure commands modularly (e.g., subcommands for different engines).
+LLM Integrations: Abstract LLM providers behind a trait (e.g., Engine trait in fluent-engines). Handle API keys securely, never hardcode them.
+Security: Validate all inputs (e.g., using validators for URLs, paths). Use secure random for sessions. Pin dependencies to avoid supply-chain attacks.
+Testing: Aim for 80%+ code coverage. Write unit tests for pure functions, integration tests for CLI commands.
+Dependencies: Minimize external dependencies. Review and audit third-party crates regularly.
+Logging: Use the log crate with levels (debug, info, error). Make logging configurable.
+Bad Habits to Avoid
+No global mutable state unless protected by mutex.
+Avoid panics; use errors instead.
+Don't ignore return values of functions that return Results.
+Avoid deep nesting; use early returns.
+No duplicated code; refactor into functions or macros.

+Project Guidelines for Fluent CLI
+Project Overview
+Fluent CLI is a Rust-based CLI tool for interacting with workflow systems and LLM providers. It emphasizes security, modularity, and ease of use.
+
+Contribution Process
+Fork and PR: Fork the repo, create a branch for your feature/bugfix, and submit a PR.
+Commit Messages: Use conventional commits (e.g., "feat: add new engine", "fix: handle error in parsing").
+Branch Naming: Use descriptive names like feature/add-zapier-support or bugfix/fix-session-id.
+Code Reviews: All PRs require at least one approval. Address all comments before merging.
+CI/CD: Ensure all tests pass. Use GitHub Actions for builds and tests.
+Project Structure
+Crates: Use a workspace with multiple crates:
+fluent-cli: Main CLI entrypoint.
+fluent-core: Shared utilities and configs.
+fluent-engines: LLM engine implementations.
+fluent-agent: Agentic features.
+fluent-storage: Persistence layer (e.g., SQLite).
+fluent-sdk: For external use.
+Docs: Maintain docs in docs/ with subfolders for analysis, guides, implementation, security, testing.
+Scripts: QA scripts in scripts/ (e.g., security audits).
+Tests: In tests/ for integration; unit tests in each crate.
+Examples: Demos in examples/.
+Development Practices
+Versioning: Follow SemVer. Update Cargo.toml accordingly.
+Dependencies: Pin versions in Cargo.lock. Review updates for security.
+Security: Follow best practices: input sanitization, secure storage of secrets, regular audits.
+Performance: Profile with tools like cargo flamegraph. Optimize hotspots.
+Accessibility: Ensure CLI output is readable (e.g., color optional, support for screen readers).
+Internationalization: Prepare for i18n if expanding.
+Tools and Environment
+Rust Version: Use the latest stable Rust (e.g., 1.79+).
+Build: Use cargo build and cargo test.
+Linting: cargo fmt, cargo clippy.
+Documentation: Use cargo doc for API docs.
+Goals for Success
+Maintain high test coverage and zero warnings.
+Keep the codebase clean and readable.
+Encourage community contributions with clear guidelines.
+Regularly release updates with changelogs.
