Tools for reproducible execution and clearer codebases.

ReproRun

A deterministic command runner for investigating flaky tests, unstable cache keys and differences between local and CI environments.

Why I built it

A failure can disappear when the same command moves between a laptop and CI. ReproRun keeps the command, environment and declared inputs stable, then gives each run a content hash so differences can be inspected instead of guessed at.

What it does

• Controls locale, timezone, random seeds and fixed time
• Restricts filesystem access with allowlists and denylists
• Hashes the command, environment, inputs and Git metadata with BLAKE3
• Caches successful artifacts by content hash

ReproRun is built for reproducibility, not untrusted-code isolation.

RepoGraph

A local-first code intelligence tool that indexes Python and JavaScript/TypeScript repositories for search, architecture and change-impact analysis.

Why I built it

Understanding a large repository often means moving between files, search results and Git history. RepoGraph keeps that context in an offline SQLite index that can be explored from the command line or a terminal UI.

What it does

• Indexes Python and JavaScript/TypeScript into SQLite and FTS5
• Explains symbols, imports, routes and related tests
• Shows change impact, import cycles and possible dead code
• Scores risk from local Git diffs and opens the graph in a TUI
