I kept losing small thoughts while browsing. The annoying part wasn’t writing the note. It was remembering where the note belonged. So TabNotes supports exact URL notes. You can leave a note on one specific page, come back later, and the note is still tied to that page.

TabNotes - Sticky Notes for Chrome Websites

Attach sticky notes to Chrome tabs, exact URLs, domains, and web pages. Save Markdown notes, reminders, screenshots, OCR text, and AI summaries.

AI Security #1 Most AI security problems don't start inside the model. They start before the request reaches it. Validate. Sanitize. Protect. Security begins at the gateway, not the prompt. #AISecurity #LLMOps #Gavio manojmallick.github.io/gavio/

Lessons from 405 Repositories #1 After analyzing 405 open-source repositories, one lesson stood out: Repository organization mattered more than repository size. A well-structured 50k-file repo was often easier to navigate than a messy 5k-file repo. #RepositoryIntelligence #OpenSource #SigMap

Interceptors #1 An interceptor is middleware for AI. Instead of changing your application code, you intercept requests and responses. One place. Many capabilities. manojmallick.github.io/gavio #Interceptors #AIGateway #Gavio

Building SigMap #1 SigMap didn't start with a repository map. It started with a frustration. I kept watching AI agents spend their first few turns searching instead of solving. That made me wonder: What if navigation became a first-class capability? #BuildingSigMap #ContextEngineering #SigMap

SigMap Under the Hood #1 Why build SigMap? Most AI agents don't struggle with writing code. They struggle with finding the right code. SigMap started as an attempt to improve navigation before generation. #SigMapUnderTheHood #ContextEngineering #SigMap

AI-Friendly Repositories #1 Your repository has two audiences: 👤 Developers 🤖 AI agents The easier it is to navigate, the faster both can contribute. Good architecture benefits everyone. #AIFriendlyRepos #ContextEngineering #SigMap

Code Relationships #1 Code doesn't exist in isolation. Every function, class, and module is connected. Understanding code starts with understanding its relationships. That's why navigation is more than opening files. #CodeRelationships #ContextEngineering #SigMap

Blast Radius #1 Changing one line rarely affects one line. Good engineers ask: "What else depends on this?" AI agents should ask the same question. #BlastRadius #AIAgents #SigMap

AI Agent Behaviors #1 An agent rarely starts by coding. It starts by building a mental model. Every file it opens changes that model. Better navigation leads to better decisions. #AIAgents #ContextEngineering #SigMap

Real-World SigMap #1 Repository: Kubernetes Question: "Where does pod scheduling start?" Reading 8M+ LOC isn't the answer. The first challenge is identifying the scheduler entry points before opening files. Good navigation beats full-repo . #RealWorldSigMap #Kubernetes #ContextEngineering

Token Economics #1 Most teams optimize models. Few optimize token spend. If 90% of the context isn't relevant, you're paying to process noise. The goal isn't fewer tokens. It's more signal per token. #TokenEconomics #ContextEngineering #SigMap

Agent Navigation #1 When developers enter a new codebase, they don't start coding. They explore. AI agents do the same. The first few files an agent opens often determine the quality of the entire session. #AgentNavigation #AIAgents #SigMap

Repository Intelligence #1 Developers don't memorize repositories. They build mental maps. Modules. Services. Dependencies. Ownership. AI agents need maps too. That's where repository intelligence begins. #RepoIntelligence #AIAgents #SigMap
