Best new developer, AI and creator resources: day 28

Best Productivity Resources turns twenty-eight days old today. Yesterday was one of the biggest directory days yet: a big wave of terminal tools, AI-agent infrastructure and open-source creator utilities. Every resource below was reviewed by hand and links straight to its original website or repository.

1. navi, a cheatsheet that lives in your terminal

navi is an interactive cheatsheet tool for the terminal. You can browse, search and run useful commands, with the arguments filled in through prompts. It can also import community cheatsheet repositories. Link: https://github.com/denisidoro/navi

2. Click for building Python CLIs

Click is a composable command-line interface toolkit for Python. It makes building well-structured CLIs with nested commands, options and prompts genuinely practical. Worth knowing: it underpins a large share of the Python tooling ecosystem. Link: https://github.com/pallets/click

3. Claude Code Game Studios, a studio made of agents

Claude Code Game Studios organises AI agents into a game-development studio structure, with specialised roles for design, code, art and production work inside Claude Code. It's a creative example of multi-agent orchestration.

4. Fast GraphRAG for better retrieval

Fast GraphRAG is a streamlined, cost-efficient take on GraphRAG for retrieval-augmented generation. It builds knowledge graphs from your data, so agents and search systems can answer with better structure and context. Link: https://github.com/circlemind-ai/fast-graphrag

5. snow-cli for agentic coding in the terminal

snow-cli is an agentic coding tool for the terminal that works with OpenAI, Gemini and Claude models, so you can switch providers and keep one workflow. You bring your own API keys. Link: https://github.com/MayDay-wpf/snow-cli

6. handmux, terminal multiplexing on mobile

handmux brings terminal multiplexer workflows to mobile, so managing persistent shell sessions on the go gets a lot easier. Link: https://github.com/search?q=handmux

7. Dormice, a self-hosted agent sandbox

Dormice is a self-hosted, E2B-compatible agent sandbox, described as the SQLite of agent sandboxes. Sandboxes live forever, idle time costs nothing, and everything runs on one machine you control. Link: https://github.com/BitMiracle-AI/Dormice

8. OpenHarness, software and hardware for coding agents

OpenHarness is open-source software and hardware for building with coding agents across software, design, circuits, data and video. It includes persistent sessions and a companion hardware device. Link: https://github.com/autonomous-ai/openharness

9. TokenOps for keeping agent tokens in check

TokenOps brings run-aware token governance to multi-agent systems. With its Python SDK and self-hosted control plane, teams can track, budget and control token usage across agent runs. Link: https://github.com/theagentplane/tokenops

10. Self-Media Compliance Review for Chinese platforms

Self-Media Compliance Review checks self-media videos before they're published, against the compliance rules of major Chinese platforms like Douyin, Kuaishou, Bilibili, Xiaohongshu and WeChat Channels. Link: https://github.com/JuneYaooo/self-media-compliance-review

11. Composerize, from docker run to compose

Composerize turns docker run commands into ready docker-compose files. It's small and instantly useful, especially when you're moving from one-off containers to repeatable setups. Link: https://github.com/composerize/composerize

12. microcharts, charts the size of a word

microcharts is a set of tiny, word-sized React charts: sparklines, micro bars and inline SVG trend lines that sit inside a sentence, table cell, KPI card or AI reply. It has zero runtime dependencies, and it's accessible and RSC-safe by default. Link: https://microcharts.dev/

13. Upscayl for sharper images

Upscayl is a free, open-source desktop app that upscales low-resolution images with AI models. The whole thing runs on your own machine. Link: https://github.com/upscayl/upscayl

More good stuff from yesterday

That's not all. The directory also picked up hol-guard, insomnia-mockbin, learn-harness-engineering, marm-memory, klaatcode, hypernovum, dispatchseo, agmsg, mulder, instar, opensquilla, colota, mira, mikrotik-mcp, cumora, claude-obsidian, prompt-master, navop, deliberation, preloop, takt, pond, train-llm-from-scratch, OneBox, mengram, openharness, guppylm, awesome-terminals, toolport, reverse-ssh, xpert and the mblode agent-skills collection.

Where to begin

Start with the friction you already feel. Try navi or Click for terminal work, Fast GraphRAG for retrieval quality, TokenOps for agent cost control, Composerize for container cleanup, microcharts for lightweight dashboards, or Upscayl for better images.
