diffctx — what a git change reaches, and the code to review it

以下摘录自该仓库的 README（片段） · 在 GitHub 读完整 README →

**diffctx tells an agent or a reviewer what a change reaches outside its
diff** — the callers, the tests that reach them, the contracts it crosses —
**and selects the code needed to understand it** under a token budget. Local,
deterministic, no index, no model calls. Caller resolution is static and per
language; where it cannot resolve, the answer says so instead of printing a
zero.
> Formerly published as treemapper — every command, flag, and API call works unchanged.
Install
pipx, pip, cargo, npm, Docker, Scoop, other MCP clients and the Python API:
integrations.
Usage
--diff takes a git range, staged, or a duration window ending now (24h,
90min, 2w). Every flag, default and exit code:
command-line reference.
How it compares
Whole-repo packers export everything; code-graph servers answer queries
against a maintained index. diffctx is **diff-seeded**: the input is a change,
the output is what it touches and what explains it. Measured results, and when
the other two fit better: COMPARISON.md.
