Claude How To fills the gap between Anthropic's feature documentation and what developers actually need to build real workflows with Claude Code. Where official docs describe what features exist, this repository shows how to combine slash commands, memory, subagents, hooks, and MCP servers into automated pipelines for code review, deployment, and documentation generation. The guide contains 10 tutorial modules with Mermaid diagrams, copy-paste configuration templates, and a progressive learning roadmap totaling 11–13 hours of structured content. Each module includes interactive self-assessment quizzes, and the entire guide is actively maintained to track Claude Code releases—currently synced to v2.2.0. Over 25 hook event types are documented with working examples, and there's a complete CLI reference for headless automation in CI/CD pipelines. Built by luongnv89 and released with an MIT license, Claude How To climbed to 18k stars in its first week—mostly organically through HN and X shares from developers frustrated with scattered official documentation. It represents the kind of community-built learning infrastructure that often outlasts the tools it documents.

Mem0 MCP Server
Open-source persistent memory layer for Claude and GPT agents

Mem0's open-source MCP server gives Claude and GPT-powered agents persistent, searchable long-term memory across sessions via the Model Context Protocol. It can be self-hosted or used through Mem0's managed cloud offering. Developers plug it into any MCP-compatible client and agents start remembering user preferences, facts, and conversation history automatically.
Reviewer scorecard
“The hook event documentation alone is worth bookmarking—25+ events with working examples is something the official docs simply don't have. The CLI headless automation reference for CI/CD is genuinely useful and hard to find elsewhere.”
“The primitive is clean: a key-value memory store with semantic search exposed over MCP, so any compliant agent client can read and write memories without custom glue code. The DX bet is that MCP becomes the universal plugin bus for agents — and if that bet holds, this is exactly the right abstraction level. The repo is real, self-hosting works with a docker-compose up, and the first 10 minutes don't require a PhD in vector databases. My one gripe is that the managed cloud pricing tiers aren't clearly documented in the README — you hit a wall where you have to leave GitHub and find the marketing site to understand what you're actually paying for at scale.”
“Community documentation guides have a well-documented half-life: they go stale fast and create confusion when they drift from the actual tool behavior. The promise to 'sync with every Claude Code release' is optimistic given it's a one-person side project. Anthropic's own docs will eventually improve, making this redundant.”
“Direct competitor is LangMem, plus whatever Anthropic and OpenAI will inevitably ship natively inside their own APIs — and that's the specific scenario where this breaks: the moment either provider bakes session memory into the model API, the self-hosting case shrinks to privacy-sensitive enterprise and the managed cloud case evaporates. What keeps this alive is the MCP-agnostic positioning and the open-source escape hatch — you can run it yourself, which creates real switching costs if teams build workflows around the memory schema. The kill scenario in 12 months is Anthropic ships native persistent memory in the API, not a competitor, and they have both the distribution and the incentive to do exactly that.”
“The fact that a community guide to using an AI tool hit 18k stars in a week tells you everything about the documentation debt the AI industry has accumulated. Claude How To is a symptom of a real problem—and a useful one while the official ecosystem catches up.”
“The thesis here is falsifiable: MCP becomes the dominant protocol layer for agent tool integration within 24 months, and memory becomes a commodity infrastructure layer that every agent needs but no single platform wants to own. That's a plausible bet — MCP adoption is tracking faster than most agent protocols before it, and Anthropic's endorsement creates genuine gravity. The second-order effect nobody is talking about: if this wins, it shifts memory ownership from the model provider to the developer or user, which is a meaningful power transfer with real privacy and portability implications. The risk is that MCP fragments into per-vendor dialects before it standardizes, which kills the cross-client portability story that makes Mem0's open-source position actually valuable.”
“The structured learning path with time estimates is a thoughtful design choice—most technical guides dump everything on you at once. Knowing upfront that advanced MCP configuration takes 5 hours lets you plan your learning rather than falling into a rabbit hole.”
“The buyer is a developer who self-hosts for free and upgrades to cloud when they hit memory volume limits — that's a real usage pattern but it's an incredibly thin conversion funnel for a company betting on managed infrastructure margins. The moat is the open-source community and the memory schema lock-in, but neither is defensible if Anthropic or OpenAI ships native persistent memory, which is not a question of if but when. The business survives exactly one scenario: they become the de facto standard before the platform players wake up, which requires aggressive enterprise distribution they don't currently have evidence of executing. Open-sourcing the MCP server is the right developer acquisition move, but there's no credible expand story between free self-host and enterprise contract that I can see from the outside.”
