Meru Patel — Toolsmith/Open to work

Instruments for clearer code.

Open-source developer tools — CLIs, TUIs and CI checks in Rust, Go, TypeScript and Python that find the signal inside noisy codebases.

Manifesto

Every codebase drifts toward noise.

A good tool is a fixed point — it measures honestly and says less than it knows.

I build instruments you can trust: local-first, open source, quiet by design.

01—The Collection

2026 — Present

Ten instruments, one obsession.

No. 01

argus

AI code review that actually understands your codebase. Bring your own model; runs on your machine or CI. Low-noise.

Rust · 2026 · AI code review · 18 stars · MIT

No. 02

graveyard

Find dead code across Python, JS/TS, Go, and Rust with git-aware confidence scoring.

Rust · 2026 · Dead-code analysis · MIT

No. 03

lantern

Local-first observability for OpenTelemetry. One binary; point your OTel exporter at localhost:4317 and inspect traces, logs, and errors.

Go · 2026 · Observability · MIT

The Index — No. 04 → 10

04 reachable Which npm advisories your code reaches, with the call path. TypeScript

05 dbfork Local PostgreSQL branching for migrations and isolated development. Go

06 conflictcast Predicts merge conflicts between open pull requests. TypeScript

07 crontui Terminal UI for cron on Linux/macOS/WSL and Task Scheduler on Windows. Go

08 dbdiff Compare database schemas, generate dialect-aware migration SQL. Go

09 couplingguard File-coupling risk in PRs from git co-change history. Zero-config CI. Python

10 churnmap Change-coupling heatmaps, force graphs and JSON from local git history. Python

02—Practice

Local-first
Open source
Self-hosted
Low noise
No telemetry

Currently: repository-aware AI review, git-aware static analysis, and product experiments at the edge of web3 and marketplaces.

03—The Person

Who holds the tools.

I'm Meru Patel. I build developer instruments from India — ten of them so far, all open source, all self-hosted: your laptop, your server or your CI.

The thread is honesty: an AI reviewer that grades your code, not its own. A scanner that ranks what's probably dead. A monitor that fits in one binary. Tools that run where you put them, answer to you, and phone home to no one.

If you're working on a problem worth measuring, I'm listening.
