It edits code in a git repository, auto-commits changes, and uses a &ldquo;repo map&rdquo; to give the LLM context about the full codebase without sending every file. This analysis covers the architectural decisions most relevant to agentic harness design: how Aider builds context, structures edits, routes between models, and verifies changes.</p> <h2 id="repo-map-pagerank-over-a-definition-reference-graph"><a href="#repo-map-pagerank-over-a-definition-reference-graph" class="heading-anchor" aria-label="Link to this section">¶</a>Repo Map: PageRank Over a Definition-Reference Graph </h2> <p>The repo map (<code>repomap.py</code>) is Aider&rsquo;s most distinctive architectural feature. Rather than dumping file contents into context, it builds a ranked summary of the codebase&rsquo;s structure — which definitions matter most given the current conversation.</p>
