Overview
CodeGraph turns a local codebase into a queryable graph of symbols, relationships, source, and evidence so agents can discover routes, flows, and change impact without rebuilding the map from scattered files. The series follows extraction, resolution, retrieval, indirect-flow handling, freshness, scale, and evaluation while keeping provenance, coverage limits, direct reads, compiler checks, and tests in the trust boundary.
Learning outcomes
- CodeGraph reduces repeated structural discovery by returning source with typed relationships, not just matching text.
- A useful graph result preserves edge type, provenance, source location, and file freshness.
- Indirect flows may be synthesized with visible uncertainty or left as explicit boundaries when evidence is weak.
- Its value is highest when cross-file discovery is the bottleneck; tiny or highly dynamic tasks may not repay the overhead.
- Graph context supports orientation and change planning, while direct reads, the compiler, and tests validate the result.

PlansFAQ
What does CodeGraph help an AI coding agent do?
CodeGraph helps an AI coding agent discover cross-file structure by returning source alongside symbols, relationships, flows, and impact context. It is a discovery aid, not runtime proof.
Can CodeGraph prove that a program will behave correctly?
No. CodeGraph provides static structural evidence; direct source inspection, the compiler, tests, and human review still validate behavior and proposed changes.
When is CodeGraph most useful?
CodeGraph is most useful when a question requires tracing routes or cross-file flows, estimating impact, or separating similarly named definitions. Tiny or highly dynamic tasks may not repay its indexing and context costs.
How should you decide whether to trust a CodeGraph answer?
Decide by checking its relationship type, provenance, source freshness, coverage boundary, and independent validation. Direct, synthesized, stale, and unresolved cases support different levels of confidence.
Does CodeGraph keep source local?
CodeGraph stores its graph locally and its viewer uses loopback, but optional anonymous telemetry may send coarse operational data unless it is disabled.
