## FileChangeCategorizer

Reviewing a pull request with hundreds of changed files is mostly a sorting problem. FileChangeCategorizer tackles that problem inside the browser: you define matching rules (for example by path, extension, or folder), and the extension applies those rules to the file list of a commit or pull request so that related changes sit together under clear labels instead of appearing as one long alphabetical list.

Because it runs as a Chrome extension, there is nothing to install on your build servers and no repository configuration to commit. It follows you across every GitHub repository you have access to, which makes it convenient for reviewers who jump between projects, open-source contributions, and client repos in the same session.

The project is published by an individual developer, has a single ~0.0.1 release from May 2024, and a small installed base. It is best treated as a focused convenience utility: install it if repetitive file sorting in pull request reviews is a real part of your day, and keep expectations modest about updates, support, and enterprise-grade features. The extension requests access to website content in order to read the file lists on GitHub pages, and its published privacy disclosure states data is not sold to third parties.

**Pricing & Plans:** Free to install from the Chrome Web Store. There is no paid tier, subscription, or in-app purchase attached to the extension.

- **Rule-based file categorization:** Define your own matching rules and let the extension sort changed files in commits and pull requests into labelled groups automatically.
- **Works directly on GitHub pages:** The categorization is applied inside the GitHub commit and pull request views you already use, with no dashboard to switch to.
- **Zero repository configuration:** Nothing is committed to your codebase and no CI setup is required, because everything runs in the browser extension.
- **Useful for large pull request diffs:** Groups of related files make sprawling diffs easier to scan and review in a logical order.
- **Simple, single-purpose design:** It does one job and stays out of the way, which keeps the mental overhead of adopting it very low.

**Strengths:** Free to install with no account required; Cuts visual noise in large pull request file lists; No repository or CI changes needed; Works on any GitHub repository you can already open

**Limitations:** Very small user base and only a single early release, so long-term maintenance is uncertain; Only useful if you regularly review large, multi-file pull requests on GitHub; Categories must be configured by hand as rules; there is no built-in smart detection; Requests access to website content in order to read GitHub pages

## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI
