A lightweight AI coding agent built in Perl and used for 6 months
CLIO is an AI coding agent built for fast, lightweight work inside a terminal. The goal was a coding helper that fits a terminal-heavy workflow without adding a large tool stack. Perl was chosen because it is already available on many Linux and Mac systems, the builder knew it well, and it is strong at text processing, which is common when working with LLMs.
The design avoids many outside dependencies, including CPAN, to reduce installation complexity and supply chain risk. CLIO has been used for 6 months on several real projects, including another AI assistant app, a Steam library manager, and CLIO’s own maintenance.
Key points
- CLIO is a lightweight AI coding agent designed for terminal-based work.
- Perl was chosen for availability, familiarity, and strong text processing.
- The design avoids many outside dependencies to lower complexity and supply chain risk.
- The tool has been used for 6 months across real coding projects and its own maintenance.
