Found 6 free Fable 5 made Claude Code skills for Opus 4.8. Sharing in case useful

not mine .. these are made by Iwo Szapar (independent, not affiliated with Anthropic)

and released free. Came across them and thought they were worth sharing here.

They're 6 Claude Code skills that nudge Claude's behavior in Opus 4.8

I did not have time to test them but what caught my attention is the tests he did .. can someone verify? I think if they are well built then maybe we can utilize them for free when fable 5 is gone ..

thoughts?

BTW i expect it to work well with codex too because its essentially a skill file.. so the same impact it had on opus 4.5 should also be everywhere across codex, gemini, or even opencode and any harness.. can work on cursor and windsurf too ... Ok i am excited

One Year into my Second Brain and I0d like to evolve it now

Hi all, I’ve been using a second brain in obsidian+local file system on my Mac (so synced w/icloud drive) since a year or so, with an mcp to query it remotely. Super cool!

Yet, I’d like to backup on GitHub or eventually mirror it on GitHub to understand differences pros and cons. I feel GitHub is a bit an all-in-one compared to other tools and many are already using it.

I am stuck as I am using the brain more as an operating system than as a context for the LLMs, editing and storing files on which I work and then I push them on the company Google Drive when they are finished or at a good point.

I make an example: Now I am planning the Q3 so I take financial data in Excel, CRM data via MCP plus Excel qualitative data, interviews, and other stuff; I put all together in a subfolder of the Q3 planning then I put an agent to work and interact with me in Claude to plan the quarter itself. The output is a markdown file that is then stored in the Q3 folder and every two weeks I iterate on these files, basically seeing if the plan is on track. They are live folders, not used only as a context. This live setup helps me with Claude code routines to have suggestions from agents of tasks, what to improve next etc.

Do you think GitHub is a good tool to do it or is it better I continue using my local environment? Any other ideas?

Rethinking Personal Knowledge #06 Why folders make us answer questions we shouldn't have to answer?

I've noticed something interesting while building my own personal knowledge system.

Folders assume every file belongs in one place.

But many files don't.

A receipt from a business trip could belong to:

  • Travel
  • Taxes
  • Work
  • Finance

None of these is wrong.

The problem is that traditional file systems make you choose exactly one.

That made me wonder whether folders are solving the wrong problem.

Instead of deciding where something belongs, maybe information should simply be discoverable from every context that makes sense.

People rarely remember where they stored something.

They usually remember what it was about.

I'm curious whether anyone else feels that folders become less useful as your archive grows.

I Built an app around Karpathy's LLM Wiki pattern for personal reading — I'm looking for beta testers

bōkpanion is an iPhone app for readers with a Karpathy-style LLM wiki at its core. You have a Socratic conversation about a book (the AI is instructed to push back, ask deeper questions), and the app builds a wiki from your discussion. Entity pages, theme pages, reader insight pages. Cross-referenced automatically. With several books, you start to notice connections you didn't notice yourself.

There's also a "reader portrait" feature — the app generates a description of your intellectual personality: recurring questions, strongest theories, blind spots. It's the most uncomfortably accurate thing I've built. Read. Think. Discuss. Grow.

Architecture is SwiftUI / SwiftData, Claude via Anthropic API, with Apple Intelligence as a free on-device fallback. Everything is stored in your Apple Cloud, so it stays private. All your saved data can be backed up and exported as OKF files.

I'm looking for 20 beta testers — serious readers with opinions. Apply here. thanks!

Obsidian + Claude Code didn’t work for me until I stopped treating it like chat

I tried the usual Obsidian + Claude Code setup for a while and honestly didn’t get the hype at first.

Pointing Claude at a vault was useful, but it still felt like chat with extra steps.

What changed was the habit around it. I started making small files for everything: rough notes, drafts, research, specs, prompts, style rules, context. Not as “notes to keep,” but as working artifacts the agent could build on.

Then the vault slowly became a system. Folders, naming, context files, repeated workflows. Nothing fancy, but enough structure for the agent to stop starting from zero every time.

That’s when it started to feel different. Slower at the beginning, much faster once the project had context and direction.

I wrote down the longer version of my workflow here, but mostly curious: has this setup clicked for others too, or are you using Obsidian + agents differently?

Rethinking Personal Knowledge #04 Why do bookmarks almost never get revisited?

I realized something while building a personal knowledge app.

Most people don't actually collect bookmarks.

They collect intentions.

"This looks useful."

"I'll read it later."

"I might need this someday."

Months later, the bookmark is still there.

But the reason you saved it is gone.

That made me wonder whether bookmarks are solving the wrong problem.

Instead of remembering URLs, maybe we should preserve the information itself, make it searchable, and connect it with everything else we already have.

Curious whether other people have noticed the same thing.

How many bookmarks do you currently have?

And how often do you actually go back to them?

Made a free iOS app to open and read raw Markdown (.md) files on iPhone/iPad — handy for peeking at Logseq pages outside the app

Logseq stores everything as plain .md files, but if you ever open one of those files directly on iOS (from Files, iCloud, Dropbox, a backup, etc.) you just get raw text. I built a small viewer to read them rendered on a phone.

Md Preview:

• Renders GitHub-Flavored Markdown — headings, tables, task lists, footnotes

• Code blocks with syntax highlighting, plus LaTeX math and Mermaid diagrams

• Opens .md / .markdown / .mdx / .rmd / .qmd from Files or the Share Sheet

• 100% on-device — no account, no uploads, no ads, no subscriptions

Free on the App Store: https://apps.apple.com/app/id6760341080

Details: https://markdown.cybergame.ai/

Not a Logseq replacement at all — just a quick way to read loose .md files when you're away from the desktop app. Curious how you all read your graph on the go.

(Open Source) Multipane agentic markdown workspace

https://preview.redd.it/b233c7qvfrah1.png?width=1080&format=png&auto=webp&s=381303990fe835205f9ac4c2ba06edb777862753

Hey everyone,

For the past couple of months, I’ve been building Neverwrite, a multi-pane Markdown workspace where you can work side by side with your agents.

I started building it because I couldn’t find the kind of workspace I wanted. It’s already pretty feature-rich, and I’d love to hear what you think, what feels useful, and what features you’d like to see added next.

Neverwrite supports images, PDFs, CSVs, Markdown, HTML, and Excalidraw maps. Agents are especially good at creating concept maps in Excalidraw, as well as HTML dashboards. You can also enable “show all files” in settings if you want to inspect code files, although the app isn’t meant to replace a coding environment, it’s designed for knowledge work. It even ships with an integrated terminal, in case you want to spin up agents from there.

I use it for studying documentation, reading papers, taking notes, generating boilerplate with agents, and building second brains. It also has an AI review layer, so changes made by agents can be inspected one by one. That was one of the main reasons I built it, I don’t like the black-box direction some tools are taking.

https://preview.redd.it/76l6x7lyfrah1.png?width=1080&format=png&auto=webp&s=afbb9b9e6cd18616a0a1999c56c63fde27efcf33

Neverwrite is fully compatible with wiki links, so you can open your existing Obsidian vaults with it. It’s also file-centric, with no proprietary file system. Your files stay yours.

The app is built with Electron, but it’s optimized and carefully put together. Electron can be very fast when it’s built well, so don’t hate the tech too quickly. It ships notarized for macOS users and is also compatible with Windows and Linux, with binaries available for Debian- and Fedora-based distros.

Enjoy! and I’d love to hear your feedback 😊

And please don’t roast me for the name. It was the most original and least crowded one I could find. I promise I’m not trying to stop anyone from writing by hand anytime soon lol.

Built a "second brain" that turns the videos I watch into my next video ideas

I watch a ton in my niche and every video sparks an idea a hook, an angle and every one died in a notes app I never reopened. So I built Margin: drop in a video, it remembers what mattered, and when you're stuck it hands you your next ideas from the stuff you've actually watched (not generic AI filler).

Been running my own channel on it and the "blank Monday" problem basically vanished. It's early and solo-built , sharing in case anyone else has the ideas-graveyard problem. What would make this genuinely useful for you?

A long-time user trying the Evernote + Claude MCP connection - my brain + Evernote/GTD/second brain + Claude + more connections - it is game changing!

TL;DR: 16-year Evernote user (~16,000 notes, full GTD system) here. The new Claude MCP connection is the missing piece I’d always wanted — something that can actually think across the whole system. It doesn’t replace Evernote’s built-in AI; it sits on top and joins your notes up with your email, calendar, files, and the wider web. Use cases I’ve been running: literature triage, grant-idea matching, GTD reviews and inbox triage, project status reports, knowledge maps and dashboards, trip and meal planning, and questions that cut across life areas. Still early days, but there’s far more here than the first wave of articles covers. Happy to hear what others are doing with it.

Claude helped me draft this note (sorry) and the mermaid diagram, and then even created the note in my Evernote, here: Reddit post — Evernote Claude MCP: what's possible (r/Evernote draft)

I really want to sincerely thank Bending Spoons for this this and all the amazing and rapid developments and improvements. And please, now that I’ve had a taste of what is possible, it would be devastating for it to not eventuate, so please keep going with the MCP!

I've used Evernote as my main second brain for about 16 years. It has grown into a bit of a beast, somewhere around 16,000 notes, with an all of life robust GTD system within it, holding most of my life: work, research, projects, reference material, personal odds and ends, lists, all of it. The new Claude MCP connection takes it to another whole new, incredible level, and I wanted to share some of what it's been like, because the articles I've seen so far only cover a small slice of what's possible.

One bit of framing first, since I've seen people get worried about this. It doesn't push out Evernote's own AI. The built-in AI is good for working inside Evernote. The Claude connection is a layer sitting on top: it can read, search and write across the whole of my notes, reason over them, and reach out to things beyond Evernote too. So the built-in AI knows my notes, and Claude joins my notes up with everything else. Also, it doesn’t replace me. I know enough about GTD that it only works well and at its best if I’m personally involved - an AI tool doing (or pretending to do) everything is just not effective at all.

Here's some of what I've been doing with it.

Research and academic work

  • Find every note tagged "study idea" (random brainstorms and more developed ideas in my "Someday" notebook) and line them up against a specific grant call. It reads them, groups them by theme, and tells me which are ready, which overlap things I'm already doing, and which are new.
  • Work through hundreds of saved article-alert emails I'd dumped in a notebook over the years, pull out the papers, grab the details, and get them ready for my reference manager. That backlog had been quietly nagging at me for ages.
  • Pull a scattered set of notes on one topic into a single up-to-date summary.
  • Draft a section of a paper or grant out of rough idea-notes I'd never joined together.

Writing

  • Take a messy brain-dump note and turn it into a proper draft.
  • I wrote this post from my own notes, and I'll save it back into Evernote as a note I can link to.

GTD, reviews and getting unstuck

  • Run my weekly review with me: go through the inbox, flag what hasn't been processed, list the projects that have gone quiet.
  • Take an inbox I've fallen behind on and pull out the urgent and important next actions, weighted by what matters to me and what's live right now, using what it can see in my email and calendar as well. This one has been a real relief.
  • Look across my projects and find the stale ones, the ones sitting there with no real next action, then either suggest a sensible next action or rewrite the vague ones into something I can do.
  • Tell me which of my open tasks it could take on, and which ones I could let go of entirely.
  • Grab one feasible thing off my someday/maybe pile when I've got a free half hour.

Maps, dashboards and the big-picture stuff

  • Generate a map of all 16,000 notes. Themes, clusters, how things connect. Think Obsidian's graph view, except it doesn't stop at drawing the lines. It can tell me why two things connect and what's missing between them.
  • Build those maps around whatever I'm chewing on that day, with no plugins to wrangle and no settings to fuss over. I ask, and it makes the view I want.
  • Dashboards and reports off the cuff. One I had it put together recently was an interactive, clickable map of all my research ideas, sorted and tagged the way I think about them.
  • Reports on how things have shifted over time. Trends across years of notes, how a theme has grown or faded, how my thinking on something has moved.
  • Audit my own system. It compared my current setup against an old "how this all works" note and showed me what I'd changed and never written down, what had drifted, and where the mess had crept in. It also turns up orphaned tags, likely duplicates, and notes filed in the wrong place.

More use cases

Personal

  • "What do I already know about this?" before a meeting or a catch-up, pulling together everything I've saved about a person, place or topic.
  • Meal planning from saved recipes, with the shopping list sent off to my tasks app.
  • Trips planned out of years of saved travel clippings.
  • A book, film or restaurant pick off my own lists that suits the mood or the occasion.
  • Finding the note I saved years ago but can't remember the words for, just by describing what it was about.

Work

  • A quick brief before a meeting, built from past meeting notes.
  • A whole project's notes boiled down to a short status update.
  • Every action item scattered across dozens of notes pulled into one list.
  • A handover or onboarding doc written out of accumulated project notes.

The joined-up part

  • Questions that cross between areas, where a note about my values, a note about a career decision and a project note all bear on the same thing, and it brings them together.
  • "How has my thinking on this moved over the years?" across a decade and a half of notes.
  • Advice grounded in my own notes, so what comes back sounds like me rather than something off the shelf.

Why it matters to me

For 16 years Evernote has been my all of life system. The Claude connection is taking it to another level. It can read the whole thing, think with it, go and check the world when it needs to, and write back. And it isn't only Evernote now. With the other connectors, my email, calendar, desktop files and cloud files are in the picture too, so things that used to sit in separate boxes are finally linked up.

Still early days, and I'm finding the limits as I go. But "only scratching the surface" feels about right. There's a lot more in here than the first round of articles let on. Happy to swap notes with other long-time users on what you're getting out of it.

I built an app to fight the feeling that I'm forgetting how to think

This is going to sound a little dramatic but bear with me.

Somewhere in the last couple of years I noticed my brain getting lazy. Why learn how something works when I can just ask an AI and move on? It's efficient, sure. But I started catching myself knowing nothing. Not the shape of a topic, not the why behind it, just a vague memory that I'd outsourced it. The knowledge would pass through me and leave nothing behind.

I didn't want the cure to be "go read a 400-page book." I love the idea of deep reading way more than I actually do it. What I actually wanted was something in between scrolling and studying. Quick, focused breakdowns of a single topic I could absorb in a few minutes and actually keep.

So I built Learnimo for myself.

The idea is simple: bite-sized topic breakdowns instead of giant book-reads. You pick something you're curious about, you get a clean breakdown, and the point is to come away actually understanding the thing, not just having seen it. You can make your own topics, share them, and fork anyone else's to make it your own. AI helps generate and shape the content, but the goal is the opposite of mindless. It's about putting knowledge back into your head instead of offloading it.

It started as a personal anti-atrophy tool. I'm putting it out there in case anyone else feels the same low-grade dread that we're all slowly forgetting how to learn.

It's on iOS, Android, and web: learnimo.co

Happy to answer anything. Would genuinely love to hear how other people are dealing with this. Am I alone here?

Why do AI tools and note taking apps still have no idea how you actually think?

Most note taking tools like Notion, Roam and Obsidian have gotten really good at storing what you think. Some even let you link notes and build graphs. But that is where they stop. And even the AI tools that have come out recently, yes they can remember what you said in a conversations and surface it back, but there is still no real active retrieval of context, no connections between your ideas, no contradictions being flagged, no hidden insights between your connected ideas and no synthesis happening across everything you have captured. They store or they remember. That is it.

But i am trying to change that gap, so here's a glimpse of what i am doing. There's an AI tool and within that, there's a thinker model which get built every time you capture or interact with the tool.

The thinker Model currently produces a structured cognitive map with these fields:

  • thinking_style
  • reasoning_direction
  • epistemic_stance
  • active_frontier
  • settled_territory
  • core_resistances
  • generative_triggers
  • dead_zones
  • drift_flags

The reason why this model is different is because, this model gets updated on two occasions, once, every time you capture any idea, thought, etc and twice, on cron job at a specific time interval which is an automatic function. So the updated model is always pulled into context by all the agents to refer whenever they are connecting ideas, finding hidden insights from your knowledge graph, developing an output and also analysing what you have captured.

One very important distinction is, the agents referring the thinker model are doing so, to not mirror or think like you. They have a role based identity which clearly lets them adapt you and help you elevate your thinking.

Think of it like notion, roam or obsidian but with full context window to become your thinking partner and not just storage of your ideas.

Do you think this is a meaningful differentiation layer?

Notion alternative…

Has any body else here had issues sticking to notion?
I would love to use notion and these other “second brain” productivity apps to organize my life, but never seem to be able to keep up with the maintenance

I’m working on a notion/ticktick/craft notes alternative that I’m planning to release for iOS and Mac.

The idea is it organizes itself and feels seamless, helping you categorize and prioritize your todos and ideas automatically based on your life context. The more you use it the more organized it gets (opposite of notion, in my experience, which becomes a mess with uncategorized todos and notes)

Would anybody here be interested in beta testing it?

You’ll get free early access and 2 years of pro subscription.

I built my second brain with an obsidian MCP

I know “second brain” gets thrown around a lot, but I mean it pretty literally.

I’ve been building a system where Obsidian is not just where I dump notes. It’s where my AI tools learn how to route, remember, and reuse the important parts of my life and work.

The core idea is simple: I don’t want AI to just answer questions from the current chat. I want it to understand the difference between a thought, a person, a project, a communication, a task, an issue, a piece of knowledge, and something that should become long-term memory.

So I built an Obsidian setup around vaults, schemas, routing rules, and MCP access. I’m calling it an Obsidian MCP because that is actually how I’ve been wiring parts of it: agents can inspect the vault structure, decide where something belongs, create notes, validate them, and connect them back to the rest of the system.

Example: I can give it a screenshot of a Facebook comment I wrote, and instead of just summarizing it, it can figure out that it belongs in People, use it to build a persona note for me, capture my tone, my sentence structure, my AI worldview, and what I actually bring into companies.

That is the part I care about.

Not “AI wrote a note.”

More like: AI understood what kind of memory this should become.

The system is still rough, but the direction feels right. Obsidian becomes the working memory layer. MCP gives agents a real operating surface. The notes stop being random markdown files and start becoming structured memory that can compound.

I’m trying to get to the point where my AI does not just know facts about me. It knows how I think, how I talk, what I care about, what projects matter, what decisions were made, and what should not be forgotten.

That feels a lot closer to a second brain than a folder full of notes.

Retrieval is quietly replacing organization and it changes what “owning your notes” actually means

A French Apple account posted something that stuck with me: since getting the new Siri, they’ve stopped filing documents and just ask Siri to find them. Faster than digging through folders.

They called it the start of a new way to organize personal data. I think they’re right and it has a consequence most note apps aren’t ready for.

Once retrieval replaces filing, the question stops being “how do I organize?” and becomes “who can reach my data, and for how long?” That’s where storage architecture quietly decides everything.

Two honest models. Database apps (notes in the app’s own store) great sync, collaboration, no file-conflict headaches; genuinely liberating cross-device.

Open-file apps (plain .md in a folder) your notes sit on disk as readable text. Both are fine day to day.
The split shows up at retrieval. A database app can expose content to Siri/Spotlight if the vendor builds and maintains that bridge. An open folder is natively readable by Spotlight, Siri, Claude, ripgrep, git, and whatever comes next no bridge, no permission, no dependency on the app still existing.

Which is why “you can export to Markdown” isn’t the same as portability. Export is a frozen copy at a moment in time, often lossy. Open files are the live thing, continuously, in every tool at once. In the agent era especially: an agent reads a .md folder natively; a database has to be exported first a dead snapshot, not a living context.

Neither model is “right.” If you want magical sync and collaboration, the database bet buys you that, at the cost of depending on a vendor. If you want your data reachable by everything, forever, open files buy you that, at the cost of solving sync yourself. Pick your trade-off knowingly.

(Disclosure: I build an open-file notes app, so I’ve clearly picked a side but this distinction holds regardless of my app, and I’d say the same to someone happy in a database tool.)
