Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Rust code-review tool for Pi. Grades your git diffs against a curated code-smells rubric (each entry: anti-pattern plus idiomatic fix) and returns categorized findings (Bug / Suggestion / Nit / Good pattern) with an Approve or Request-Changes verdict. Not

Readme

@estebanforge/pi-rust-review

Rust code review against the Rust Code Smells & Idiomatic Anti-Patterns guide. Registers a rust_review tool that reads git diffs, filters to .rs files, attaches the guide, and for each finding flags the smell and proposes the idiomatic fix (corrected code).

Sibling to @estebanforge/pi-go-review. Pair with cargo clippy for compiler-grade lint coverage; this tool focuses on design and idiomatic mistakes clippy may not flag.

Install

pi install npm:@estebanforge/pi-rust-review

Usage

Ask Pi: "review my Rust changes."

The tool runs git in one of five modes:

| Mode | Description | Needs ref | | --- | --- | --- | | working | Unstaged changes | No | | staged | Staged (cached) changes | No | | all | All changes vs HEAD | No | | commit | A specific commit | Yes (SHA) | | range | A commit range | Yes (e.g. main..HEAD) |

Narrow scope with path (a file or directory). The tool runs git from that path — so path can point into a nested repo (e.g. a crate inside a workspace whose root is not itself a git repo).

What it does

  1. Reads the git diff filtered to *.rs.
  2. Attaches the Rust Code Smells guide (anti-pattern + idiomatic fix for each).
  3. The LLM reviews the diff and returns findings that propose the fix:

| Severity | Meaning | | --- | --- | | Bug / Critical | Must fix | | Suggestion | Should consider | | Nit | Minor improvement | | Good pattern | Well done |

Each finding cites the section + anti-pattern name, the file + code fragment, and a corrected snippet modeled on the guide's idiomatic-fix examples. Ends with a Verdict: Approve / Request Changes / Needs Discussion.

Guide sections

| Section | Anti-patterns | | --- | --- | | 1. Error Handling Traps | Excessive .unwrap() · Sentinel values (-1 / "") | | 2. API Design & Type Architecture | &String/&Vec<T> indirection · Two-state uninitialized objects · Hardcoded file inputs | | 3. String & Path Manipulation | Paths as strings · String-concatenation loops | | 4. Lifetimes & Memory Mismanagement | Unnecessary .clone() · Overused smart pointers (Rc<RefCell<T>>) · Conflicting reference lifetimes |

The full guide ships as a bundled, editable extensions/rust-smells.md.
