Tools for reviewing code in the agentic era.

git diff	deltoids

Hunks expand to show the enclosing function, so you always know where you are.

Overview

Deltoids diffs have language-aware syntax highlighting and word-level highlighting within changed lines. They also expand to include relevant context, usually the enclosing function or struct up to 200 lines. This allows you to quickly view the entire context without having to switch to an editor.

Tools:

• deltoids pager: ANSI diff filter for less / core.pager
• deltoids review: review tool
• deltoids edit: file edit tool (used by coding agents)
• deltoids write: file write tool (used by coding agents)
• deltoids traces: trace browser to follow agents in real-time

`edit` and `write` are CLI versions of AI coding agent tools. By providing these custom CLIs, we can tell coding agents to generate summaries for each change and visualize them with `deltoids traces` separately from the coding agent UI.
