Inline Comment is a skill published by agensi that gives developers a browser-based editor for leaving anchored feedback on code, configuration files, and documentation. Instead of quoting snippets or citing line numbers in chat, a developer selects the exact lines or code spans they want to address and writes a comment there. When submitted, the skill sends the AI a structured JSON object in which each comment is mapped precisely to the selected region, so the agent receives unambiguous instructions without requiring extra context-copying.
The editor supports syntax highlighting for over 80 languages and can render Markdown, KaTeX math expressions, and Mermaid diagrams. Code folding lets reviewers collapse sections of long files to navigate efficiently. The interface is designed with touch-sized targets and a responsive layout, so reviews can be submitted from a phone or tablet. It also operates over SSH port forwarding or HTTP tunnels, making it usable when working on remote machines through a local browser. Draft comments are saved automatically in the browser, so an accidentally closed tab does not discard in-progress work.
Supported file types include source code in languages such as Python, JavaScript, Rust, and Go; configuration formats like YAML, JSON, and Dockerfile; and documentation formats including Markdown and LaTeX. This skill is appropriate when an agent workflow requires precise, location-specific human feedback on text or code, rather than free-form conversational instruction.
