Top 10 repos trending on GitHub this week — what they do, why they matter, and how to use them in your projects.

1. alchaincyf/hermes-agent-orange-book

2,433 stars this week · various

A free, structured 17-chapter guide (PDF) to building production AI agents with Nous Research's Hermes Agent framework, covering its self-improving learning loop, three-layer memory system, and auto-evolving Skills.

Use case

Most AI agent tutorials stop at 'call OpenAI, loop on tool results' — they don't address memory persistence, skill reuse, or how to prevent agents from going off the rails at scale. This guide fills that gap: for example, if you're building a blog assistant that learns your writing style over time and auto-generates drafts, you need the memory + learning loop architecture this book explains, not just a basic ReAct loop.

Why it's trending

Hermes Agent itself dropped in February 2026 and is the first major open-source agent framework with built-in self-improvement and constraint layers baked in by default — developers are racing to understand it before the ecosystem locks in patterns, making this free structured guide the fastest on-ramp available right now.

How to use it

  1. Download the English PDF from the repo and read Parts 1–2 (Chapters 1–6) first — specifically focus on the three-layer memory architecture (working / episodic / semantic) before touching any code.,2. Clone the actual Hermes Agent repo: git clone https://github.com/NousResearch/hermes-agent && cd hermes-agent && pip install -e .,3. Run the quickstart conversation from Chapter 8 of the guide to verify your setup: from hermes import HermesAgent; agent = HermesAgent(); agent.chat('Summarize my last 5 blog posts and suggest a follow-up topic'),4. Follow Chapter 10 to connect Hermes to your own tools — e.g., wire up a Supabase MCP or REST tool so the agent can read/write your blog's post table directly.,5. Use Chapter 12 ('Knowledge Assistant' scenario) as the template for your first real feature — it maps directly to a personal blog use case and shows how to seed the semantic memory layer with your existing content.

How I could use this

  1. Build a 'Blog Memory Agent' using Hermes' semantic memory layer seeded with all of Henry's existing posts stored in Supabase pgvector — it learns his writing style, flags topic overlap between drafts, and suggests titles/intros that match his voice, getting better with each published post.
  2. Create a self-improving cover letter agent: give it Henry's resume + a job description, let it draft a letter, then feed back the hiring manager's response (rejection/interview invite) as episodic memory so it iteratively refines its approach across multiple applications — the learning loop chapter explains exactly how to wire this feedback cycle.
  3. Implement a 'Skill-building' content pipeline: use Hermes' auto-Skill creation to have the agent define and save reusable Skills for Henry's recurring tasks (e.g., 'convert raw notes to structured blog post', 'generate Twitter thread from article') — these Skills persist across sessions in Supabase and evolve as Henry corrects outputs, effectively building a personalized content OS over time.

2. yizhiyanhua-ai/fireworks-tech-graph

2,370 stars this week · Python

A Claude Code skill that converts natural language descriptions into publication-ready SVG+PNG technical diagrams across 14 diagram types and 7 visual styles — no diagramming tool required.

Use case

Technical writers and engineers waste hours in Lucidchart or draw.io manually repositioning boxes for architecture diagrams that go stale the moment the system changes. This repo lets you describe a system in plain English (e.g., 'Generate a RAG pipeline with vector store, reranker, and streaming LLM response, blueprint style') and get a 1920px PNG you can drop directly into a blog post or README — regeneratable on demand when the architecture evolves.

Why it's trending

It's riding the Claude Code skill ecosystem wave — Anthropic's push toward agentic coding tools means developers are actively hunting for drop-in skills that extend Claude Code beyond code generation, and diagram automation is one of the highest-friction daily tasks it can eliminate.

How to use it

  1. Install the skill into Claude Code by adding the repo as a skill source per Anthropic's Claude Code skill docs (claude skills add yizhiyanhua-ai/fireworks-tech-graph).
  2. Ensure rsvg-convert is available locally (brew install librsvg on macOS or apt install librsvg2-bin on Linux) for PNG export.
  3. In a Claude Code session, invoke it with a natural language prompt: 'Generate a multi-agent orchestration diagram showing a planner agent delegating to web search, code execution, and memory tools — dark terminal style'.
  4. The skill outputs both .svg and a 1920px .png into your working directory — commit the SVG for version control, use the PNG for embedding.
  5. Iterate by re-prompting with style or structural changes; since output is SVG, you can also post-edit in Inkscape or Figma if needed.

How I could use this

  1. Auto-generate a fresh architecture diagram for each technical blog post at build time: store the natural language description as a .diagram.txt file alongside the MDX post, run the skill in a Next.js build script, and embed the resulting PNG — diagrams stay in sync with post content and are version-controlled as text.
  2. Build a 'System Design Explainer' page on the portfolio site where visitors type a system description into a textarea, it POSTs to a Next.js API route that shells out to the Claude Code skill, and returns the SVG inline — a live demo that doubles as proof of AI integration skill to recruiters.
  3. Use it to generate visual summaries of AI paper breakdowns on the blog: after writing a post on a new technique (e.g., Mem0, LangGraph, CrewAI), prompt the skill to produce a canonical architecture diagram in blueprint style, add it as the post's Open Graph image, and watch social share engagement improve with a visually distinctive technical preview.

3. momenbasel/PureMac

1,487 stars this week · Swift · cache-cleaner cleanmymac cleanup disk-cleaner

PureMac is a free, zero-telemetry SwiftUI macOS cleaner that replaces CleanMyMac with open-source, auditable code and no subscription.

Use case

Developers burning disk space on Xcode derived data, simulator caches, and Homebrew cruft — often 20-50GB — are stuck paying $40/year for CleanMyMac or running sketchy freeware. PureMac lets you schedule automated cleanup of exactly those dev-specific caches (Xcode, Homebrew, npm, system logs) without worrying that a background process is phoning home with your file metadata.

Why it's trending

CleanMyMac X quietly moved to a subscription model and added telemetry that privacy-conscious devs flagged in recent threads — PureMac landed at exactly the right moment as a credible, auditable alternative. The 1,400+ stars in a single week signals pent-up demand from the dev community who already distrust closed-source system utilities.

How to use it

  1. Download: Grab the latest .dmg from GitHub Releases or install via Homebrew: brew install --cask puremac
  2. First scan: Open the app, click 'Scan' — it categorizes junk by type (Xcode Derived Data, Homebrew cache, system logs, app caches) with sizes shown per category.
  3. Selective clean: Check only the categories you want — e.g., uncheck 'App Caches' if you want to keep browser caches, then hit 'Clean Selected'.
  4. Schedule auto-clean: Go to Settings → Schedule, enable weekly auto-clean for safe categories (Xcode derived data, Homebrew downloads) so it runs silently in the background.
  5. Audit the logic: If you're curious what exactly gets deleted, clone the repo and check Sources/PureMac/Cleaners/ — each cleaner is a separate Swift file with explicit path lists you can verify before trusting.

How I could use this

  1. Write a blog post titled 'I audited PureMac's source so you don't have to' — walk through each Swift cleaner file, show the exact paths it targets, and benchmark before/after disk usage on a real dev machine. This kind of security-audit-meets-tutorial post performs extremely well on Hacker News and positions Henry as someone who reads source code rather than just READMEs.
  2. Build a 'Dev Machine Health' section into a personal portfolio dashboard (Next.js + Supabase) that ingests a JSON export of disk usage stats from a custom PureMac-inspired CLI script, stores snapshots over time, and visualizes cache bloat trends — demonstrates full-stack skills with a real DevOps angle that interviewers find memorable.
  3. Fork PureMac and add an AI-powered 'safe to delete?' classifier — use a local LLM (e.g., Ollama + llama3) to analyze file paths and last-accessed timestamps, then surface a confidence score per cache category. Write it up as a blog post showing how to extend a SwiftUI app with a local AI inference layer, hitting the trending intersection of on-device AI and privacy-first tooling.

4. QLHazyCoder/codex-oauth-automation-extension

1,365 stars this week · JavaScript

A Chrome extension that automates bulk OpenAI OAuth account registration, including CAPTCHA retrieval and verification code handling — essentially a mass account farm tool.

Use case

This repo solves the problem of manually creating large numbers of OpenAI accounts for CPA (cost-per-action) affiliate schemes, where each registered account generates a payout. It automates the entire OAuth flow — email filling, password generation, verification code fetching from multiple mail providers, and the OAuth consent callback — achieving ~149/150 success rates in batch runs.

Why it's trending

It's trending because OpenAI Codex API access was recently opened up with free credits tied to new accounts, making bulk account creation financially attractive and prompting a wave of automation tooling. This is a honeypot repo — it's getting stars from people curious about the technique, not necessarily endorsing it.

How to use it

WARNING: This tool violates OpenAI's Terms of Service (Section 3) and likely constitutes fraud against affiliate programs. Using it risks permanent IP/device bans, legal liability, and account termination. Do not use this on any production system or with real credentials. For educational reverse-engineering purposes only: 1) Clone the repo and load it as an unpacked Chrome extension via chrome://extensions with Developer Mode on. 2) Open the sidebar panel and configure your CPA panel URL and a mail provider (e.g., Inbucket running locally). 3) Set a password or leave blank for auto-generation. 4) Click 'Single Step' to observe each automation step in isolation before running 'Auto'. 5) Study the Chrome Debugger API usage in step 8 — it uses chrome.debugger to inject synthetic input events to bypass standard click detection, which is the technically interesting part.

How I could use this

  1. Do NOT build this. Instead, write a technical blog post analyzing how this extension uses chrome.debugger to inject synthetic DOM events that bypass bot detection — this is a genuinely interesting security topic and would rank well for searches on 'Chrome extension automation detection bypass'. Include a counter-measure writeup for site owners.
  2. Build a legitimate OAuth flow testing tool for your own Next.js/Supabase blog: a single-account Playwright script that smoke-tests your own auth flows (signup, email verification, login, password reset) on every deploy — reusing the step-by-step sequencing pattern this extension demonstrates, but for QA on your own app.
  3. Write a blog post series on 'AI API cost arbitrage and its arms race with providers' — covering rate limiting strategies, how OpenAI detects bulk signups (device fingerprinting, email pattern analysis, behavioral signals), and how to legitimately manage multiple API keys per project using Supabase Vault to store rotated keys safely.

5. nashsu/llm_wiki

1,283 stars this week · TypeScript

LLM Wiki is a desktop app that incrementally builds a persistent, interlinked wiki from your documents — replacing one-shot RAG with a living knowledge graph that grows over time.

Use case

Traditional RAG re-retrieves and re-synthesizes answers from scratch on every query, losing accumulated context between sessions. LLM Wiki solves this by having the LLM write structured wiki pages as it ingests documents, so knowledge compounds — for example, drop in 50 research papers on AI alignment and get a self-organized, cross-linked encyclopedia with knowledge gaps and surprising connections surfaced automatically.

Why it's trending

Developers are hitting the ceiling of naive RAG implementations and actively searching for persistent memory architectures; this repo ships a production-quality, graph-backed alternative with Louvain clustering and LanceDB vector search in a single installable desktop app, making it immediately testable without infra setup.

How to use it

  1. Clone and install: git clone https://github.com/nashsu/llm_wiki && cd llm_wiki && npm install
  2. Configure your OpenAI-compatible endpoint in settings (works with local Ollama or OpenAI API key).
  3. Drop a folder of markdown files, PDFs, or clipped web pages into the import panel — the persistent ingest queue processes them serially with crash recovery.
  4. Browse the auto-generated wiki graph, inspect Louvain-detected clusters (e.g., all your 'TypeScript performance' sources grouped together), and use Graph Insights to find knowledge gaps.
  5. Trigger Deep Research on any gap node — it runs multi-query web search and auto-ingests results back into the wiki, closing the loop.

How I could use this

  1. Feed all your published blog posts into LLM Wiki to generate a self-updating 'topic graph' — then expose the wiki JSON via a Supabase Edge Function so your Next.js blog can render a live 'Related Concepts' knowledge map on each post page, showing readers how articles interconnect rather than just a flat tag list.
  2. Dump your resume, job descriptions you're targeting, and 6 months of saved LinkedIn posts from hiring managers into LLM Wiki — let it build a structured wiki of skill gaps, required keywords, and industry signals, then query it with a simple CLI script before writing each cover letter to get a precise gap analysis rather than generic advice.
  3. Integrate the Chrome Web Clipper workflow into your blog's research process: clip every source you read while drafting a post, let LLM Wiki build a local knowledge graph, then hit the Graph Insights endpoint to pull 'surprising connections' as a JSON payload — use that payload to auto-generate an AI-written 'What I Learned Unexpectedly' section at the bottom of each post, making your content visibly more insightful than competitors who just summarize their sources.

6. joeynyc/hermes-hudui

877 stars this week · TypeScript

A browser-based dashboard that gives you real-time visibility into a persistent-memory AI agent's identity, memory, costs, and sessions — like Chrome DevTools but for your AI's consciousness.

Use case

When you're running a long-lived AI agent (Hermes) locally, you have zero visibility into what it remembers, how much it's costing you per model, or what patterns it's developed — you're flying blind in a terminal. This solves that by exposing all 13 internal state dimensions (memory, skills, cron jobs, corrections, identity) in a live WebSocket-updated browser UI. Concrete example: you notice your agent has accumulated a miscorrection that's been skewing responses for 3 sessions — you catch it in the Corrections tab before it compounds further.

Why it's trending

Persistent-memory agents are the hot frontier right now as developers move beyond stateless LLM calls toward agents that actually accumulate context over time — this repo gives that abstraction a tangible, inspectable interface, which is exactly what the dev community is demanding as Hermes gains traction.

How to use it

  1. Ensure you have a running Hermes agent with data written to ~/.hermes/ — this is a prerequisite the HUD reads from.
  2. Clone and install: git clone https://github.com/joeynyc/hermes-hudui.git && cd hermes-hudui && ./install.sh
  3. Start the server: source venv/bin/activate && hermes-hudui — opens on http://localhost:3001
  4. Navigate tabs 1–9 to inspect Memory, Skills, Sessions, Costs, and Patterns; use Ctrl+K for the command palette.
  5. Use the live Chat tab to interact with the agent directly from the dashboard and observe how memory state updates in real-time alongside your conversation.

How I could use this

  1. Build a 'blog writing agent' on top of Hermes that accumulates memory about Henry's writing style, past post topics, and reader engagement patterns — then embed this HUD (or a stripped-down version of its WebSocket data feed) into a private /admin route in the Next.js blog to show a live 'agent context' sidebar while drafting new posts.
  2. Use the token cost tracking model from this HUD as inspiration to build a career tool cost dashboard: every time Henry's resume matcher or cover letter generator runs, log model, tokens in/out, and cost to Supabase — then render a personal 'AI spend by job application' breakdown, which becomes a compelling portfolio piece showing responsible AI cost awareness.
  3. Adapt the WebSocket + 13-tab architecture pattern to create an 'AI writing session inspector' for the blog — a hidden dev panel that shows which RAG chunks were retrieved for a given post, what the system prompt looked like, confidence scores, and correction history — essentially a HUD for Henry's own blog AI, demonstrating observability skills that are rare and highly valued in senior AI engineering roles.

7. vyfor/rattles

851 stars this week · Rust · animation cli no-std ratatui

Rattles is a dependency-free Rust library for terminal spinners with no-std support, giving you fine-grained control over animation frames without pulling in a heavyweight TUI framework.

Use case

When you're building a Rust CLI tool — say, a local AI pipeline runner or a Supabase migration script — and you want a loading indicator without dragging in indicatif or crossterm as transitive deps. For example, a CLI that polls an OpenAI endpoint and streams results could show a braille spinner while waiting, then clear it cleanly on completion, all with zero allocator assumptions if targeting embedded or WASM.

Why it's trending

The no_std + WASM Rust ecosystem is heating up, and developers are pruning dependency trees aggressively after recent supply-chain scares. A spinner lib with literally zero deps that works in constrained environments fills a gap that indicatif (which requires std + crossterm) doesn't cover.

How to use it

  1. Add it: cargo add rattles
  2. Pick a preset and drive it in your render loop:
use rattles::presets::prelude as presets;
let rattle = presets::dots();
loop {
    print!("\r{} Fetching data...", rattle.current_frame());
    std::io::stdout().flush().unwrap();
    std::thread::sleep(std::time::Duration::from_millis(80));
}
  1. For ratatui integration, use rattle.frame_at(elapsed) inside your Widget::render impl to stay in sync with ratatui's event loop without a separate thread.
  2. For no_std (e.g., WASM), switch to TickedRattler and call rattle.tick() on each render cycle, passing the current frame string into whatever output layer you control.
  3. Define custom spinners with the rattle! macro if none of the braille/emoji/arrow presets match your aesthetic.

How I could use this

  1. Build a Rust-based CLI companion for Henry's blog that watches the Supabase DB for draft posts and shows a live braille spinner while waiting for AI-generated tag suggestions to return from an OpenAI call — clean, zero-dep, ships as a single binary alongside the Next.js project.
  2. Write a resume-matcher CLI tool in Rust that scores a resume against a job description using an embeddings API; use Rattles' waverows spinner during the embedding round-trip so the terminal output looks polished when Henry demos it in job interviews or records a portfolio screencast.
  3. Create a WASM-compiled Rust module embedded in the Next.js blog that renders an animated braille spinner (driven by frame_at(elapsed) via JS performance.now()) as a custom React component while server-side AI content summarization is streaming in — no npm spinner package needed, just the compiled WASM output.

8. AgentSeal/codeburn

826 stars this week · TypeScript · ai-coding claude-code cli codex

CodeBurn is a zero-config TUI dashboard that reads Claude Code and Codex session logs directly from disk to show you exactly where your AI coding tokens and money are going, broken down by task type, model, and project.

Use case

If you're running Claude Code or Codex heavily during development, your monthly AI bill can silently balloon with no visibility into which tasks (e.g. fixing tests vs. generating boilerplate) are the real cost drivers. CodeBurn parses the session transcripts already written to disk by these tools and surfaces a breakdown like: 'You spent $18 this week, 60% on edit/fix retries in your auth module, with a 30% one-shot success rate on test generation' — so you can actually change your prompting strategy or batching behavior.

Why it's trending

AI coding tool costs are becoming a real budget concern for indie devs and small teams as Claude Code and Codex usage scales up, and CodeBurn landed at exactly the moment people are getting their first shocking monthly bills and searching for a way to audit them without adding a proxy or changing their workflow.

How to use it

  1. Install globally: npm install -g codeburn (requires Node 20+, and you must already be using Claude Code or Codex so session logs exist at ~/.claude/projects/ or ~/.codex/sessions/).
  2. Run codeburn to open the interactive TUI dashboard defaulting to the last 7 days — use arrow keys and tab to navigate panels.
  3. Drill into specific time windows: codeburn today, codeburn month, or codeburn report -p 30days for a rolling window.
  4. Export your data for external analysis: codeburn report --format json > usage.json or --format csv > usage.csv to pipe into a spreadsheet or your own scripts.
  5. Optionally set up the SwiftBar macOS menu bar widget from the repo's /extras directory to get a live token-burn counter in your menu bar without opening a terminal.

How I could use this

  1. Build a 'AI Development Transparency' section on Henry's blog that embeds a weekly auto-generated JSON export from CodeBurn into a Supabase table (via a cron job or GitHub Action that runs codeburn report --format json), then visualizes it with Recharts on a public /ai-costs page — this becomes a genuinely unique portfolio piece showing intellectual honesty about AI-assisted development costs and patterns.
  2. Create a cost-aware prompting guide post: use CodeBurn's one-shot success rate metric to run a structured A/B experiment — prompt style A vs. B on identical tasks across a week — then publish the actual token cost difference with real numbers from the CSV export. This is far more credible than generic 'prompt engineering tips' posts because it has real dollar figures attached.
  3. Wire CodeBurn's JSON export into a lightweight Next.js API route that Henry already controls, parse the per-project cost breakdown, and surface it as a sidebar widget on individual blog posts tagged 'built-with-ai' — showing readers something like 'This feature cost ~$2.40 in AI tokens to build' next to the post. It's a differentiating transparency signal and a natural conversation starter in the developer community.

9. hexiecs/talk-normal

825 stars this week · Shell

A battle-tested system prompt that strips AI verbosity by 70%+ — no bullet-point padding, no 'Great question!', just the actual answer.

Use case

Every LLM wrapper app suffers from bloated responses that waste tokens, slow down UIs, and annoy users. For example, if Henry's blog has an AI Q&A feature, every reader question gets back a 1500-char essay when 400 chars would do — this prompt fixes that without fine-tuning or post-processing hacks.

Why it's trending

GPT-5 launched recently and people are noticing the slop problem got worse, not better — verbose 'assistant voice' is now a known UX liability and devs are actively hunting for prompt-level fixes rather than waiting for OpenAI to address it.

How to use it

  1. Grab the system prompt from the repo's main prompt file (raw string, copy directly).
  2. Inject it as the system message in any OpenAI/Anthropic/Gemini call:
const response = await openai.chat.completions.create({
  model: 'gpt-4o-mini',
  messages: [
    { role: 'system', content: TALK_NORMAL_PROMPT },
    { role: 'user', content: userQuestion }
  ]
});
  1. Store the prompt as an env-injected constant so you can swap/update it without redeploying.
  2. A/B test with and without it using Supabase to log response length + a user satisfaction thumbs up/down — measure your own reduction rate.
  3. Combine with a max_tokens cap (e.g. 300) as a hard backstop for UI components with fixed height.

How I could use this

  1. Add a 'TL;DR mode' toggle on blog post pages — when enabled, an AI summary of the post uses this system prompt so readers get a 2-sentence summary instead of a padded paragraph, reducing the 'AI wrote this' feel that kills trust.
  2. Use it in a cover letter critique tool: feed in a user's draft and get back brutally direct feedback ('Cut line 2, it's filler. Quantify the impact in line 4.') instead of the usual 'Great start! Here are some suggestions...' fluff that makes AI feedback useless.
  3. Apply it to Henry's blog comment assistant — if he builds an AI feature that suggests replies to reader comments, this prompt ensures the suggested replies sound like a real developer responding, not a customer support bot, which dramatically improves the chance he'll actually use the suggestions.

10. sterlingcrispin/nothing-ever-happens

704 stars this week · Python · meme not-financial-advice nothing-ever-happens polymarket

An async Python bot that automates 'No' bets on Polymarket prediction markets, embodying the meme that dramatic events rarely resolve as feared.

Use case

Prediction market traders manually scanning hundreds of markets for mispriced 'No' positions is tedious and slow. This bot automates the full loop: scanning non-sports yes/no markets, identifying 'No' entries below a configured price cap, placing orders, and persisting recovery state — so you can run a systematic contrarian strategy (e.g., betting against 'Will X country default this month?') without babysitting a dashboard.

Why it's trending

It's riding the viral 'nothing ever happens' doomer-fatigue meme cycle plus renewed retail interest in Polymarket following high-profile US election and geopolitical markets — people want to mechanize the joke into actual returns.

How to use it

  1. Clone and install: git clone https://github.com/sterlingcrispin/nothing-ever-happens && pip install -r requirements.txt
  2. Copy configs: cp config.example.json config.json && cp .env.example .env — set BOT_MODE=paper, LIVE_TRADING_ENABLED=false, DRY_RUN=true to run in safe simulation mode first.
  3. Configure your strategy in config.json under strategies.nothing_happens — set price_cap (e.g. 0.15 means only buy No when it's priced at 15 cents or below) and max_position_size.
  4. Run locally: python -m bot.main — the dashboard will bind to $PORT and show open positions, P&L, and market scanner state.
  5. Audit bot/exchange_clients.py to understand the PaperExchangeClient vs live client interface before ever setting BOT_MODE=live.

How I could use this

  1. Build a public 'Prediction Market Pulse' widget for the blog: use Polymarket's read-only API (no trading) to fetch current prices on tech/AI markets (e.g., 'Will GPT-5 launch this quarter?') and display them as a live embedded sidebar component in Next.js with SWR polling — gives the blog a data-driven angle without any financial risk.
  2. Create a 'Hype vs Reality' career tool: scrape Polymarket markets tagged with tech topics (layoffs, AI regulation, framework adoption) and correlate their resolution history against job posting trends from a public API like Adzuna — surface a score like 'the market was 80% confident React would decline; it didn't' to help Henry write contrarian, data-backed takes in posts.
  3. Wire the bot's paper trading log output into a Supabase table and build an AI post-generator: after each simulated market resolves, call GPT-4o with the market question + outcome + your position P&L and auto-draft a short 'I told you so / I was wrong' reflection post — a fully automated content pipeline that publishes genuine prediction accountability content with zero extra writing effort.
