Worked on improving the usability of the iota CLI within the iotaledger/iota repository by removing deprecated commands and cleaning up dead code. Focused on aligning the command-line interface with the project's deprecation plan, the developer eliminated outdated commands such as start, genesis, genesis-ceremony, and fire-drill, while guiding users toward updated alternatives. The work involved consolidating maintenance by reducing the codebase by approximately 56 lines and ensuring long-term stability. All changes were validated using Rust tooling, including cargo build, cargo clippy, and nightly formatting checks, demonstrating a methodical approach to CLI development and codebase hygiene in Rust.
