I used Claude to review the book *Why Machines Learn*. Then I went through each chapter while Claude questioned me at relevant points. To make the concepts more concrete, I used interactive graphs with x and y axes. The first graph shows the relationship between x and a function, along with the slope of the curve. It uses f(x) = x³ with a tangent line illustrating the derivative. I can drag a slider to move the point and watch the slope change, then switch to 3x to compare it with a straight line. The graph demonstrates several ideas: - Sliding x to 0 on x³ makes the tangent flat and the slope 0, so a small nudge barely changes the output. This is similar to a flat spot at the ends of a sigmoid, where learning stalls. - Sliding to 2 and then to −2 shows a slope of 12 at both points. Because the derivative is 3x², it is positive on both sides and the curve is always climbing. - Switching to 3x makes the tangent lie directly on top of the line, with a constant slope of 3 everywhere. - The nudge-check box tracks the derivative closely, showing that the derivative is essentially “change in output ÷ small change in input.” The second graph shows the input and output layers of a small pattern detector. It represents a 2 × 2 image flattened into four inputs, a hidden layer of two neurons, and two outputs. The weights are set by hand so the network can distinguish a vertical line from a horizontal one. I can click the pixels to change the image and watch the numbers flow through the network. The setup uses weight +1, weight −1, ReLU activation defined as max(0, z), softmax output, and all biases set to 0. For example: - Flatten: x = [1, 0, 1, 0] - h1 = ReLU((1)(1) + (-1)(0) + (1)(1) + (-1)(0)) = ReLU(2) = 2 — left column versus right column - h2 = ReLU((1)(1) + (1)(0) + (-1)(1) + (-1)(0)) = ReLU(0) = 0 — top row versus bottom row - Output: scores (2, 0) → softmax → Vertical 88%, Horizontal 12% The graph includes examples for a left vertical line, top horizontal line, right vertical line, and diagonal. Seeing the numbers change as the factors change really helps bring these concepts to life for me. Step-by-step: 1. I used Claude to review *Why Machines Learn* and question me as I worked through each chapter. 2. I used an interactive x-and-y graph to explore how a function changes and how its slope relates to the derivative. 3. I moved the slider across f(x) = x³, including 0, 2, and −2, to observe how the tangent and slope changed. 4. I switched the graph to 3x and used the nudge-check box to compare a constant derivative with the changing derivative of x³. 5. I explored a second interactive diagram representing a 2 × 2 image, four inputs, two hidden neurons, and two outputs. 6. I clicked different pixels and watched the ReLU activations, output scores, and softmax predictions change for vertical, horizontal, and diagonal patterns.

I built a workflow in which AI agents build a product under the kind of governance I’d expect from a senior engineering team. After 20 years in software engineering, including 10 years running my own businesses, I learned that writing code isn’t the hard part. Keeping control of it is. So I set up a build loop on GitHub. One thing I’ve kept for myself is decision-making: approving plans, answering product questions, and signing off on what the system has learned. The product it’s building is Cordexa, a tool for document-heavy expert work, such as quantity take-offs from engineering drawings or assessing a tender against a company’s own CVs and case studies. It’s designed to run inside the customer’s own cloud, so their documents never leave it. Every figure is cited to the document it came from or flagged for a person. It never guesses. The problem it solves is complex, but the build loop lets the system work in the background and notify my phone when it needs a decision. That allows me to stay focused on my day job. Step-by-step: 1. I start every module with a plain-English plan and approve it before any code exists. 2. One agent writes the tests from the plan. A different agent writes the code, and it cannot modify the tests. 3. An independent reviewer agent checks every change against its plan. Safe changes merge automatically; anything that changes the product waits for my approval. 4. A watchdog checks every 15 minutes for anything that is stuck, fixes it when possible, or tells me why it cannot. 5. Real test jobs run after every merge and are scored against known answers, so progress is measured rather than guessed. 6. I handle the decisions, answer product questions, and sign off on what the system has learned.

I built WarrantKit, an open-source (Apache-2.0) kill switch for AI agents. Each agent run receives a Warrant: a typed contract that specifies what the agent may do, for how long, and under which policy. A gateway checks every action before it reaches the outside world. When containment triggers, the runtime’s epoch advances, immediately invalidating every Warrant issued under the old epoch instead of allowing it to linger until a timer expires. Evidence of what happened remains separate from authority, and receipts can be verified offline with a standalone Python script. I designed the architecture and threat model, then used AI coding assistants for most of the implementation. I reviewed everything against an adversarial test suite and a real-host enforcement demo that others can run themselves. Before writing the mechanisms, I wrote tests for the attacks: replayed runtime reports, tampered event sequences, evidence attempting to upgrade itself into authority, and authority carried across execution boundaries. The suite has 202 passing tests, and several core behaviors exist because a test caught the system trusting too much. One example is a recovered runtime carrying a stale report into a new epoch. I then proved enforcement on a real Linux host with a cgroup-v2 real-kill demo before claiming it. The no-root demo is simulated, and the README says so. It also lists what WarrantKit is not. The architecture is layered: WarrantKit owns the authority lifecycle and verification; AgentContainment owns the enforcement boundary; and Warden, DProvenanceKit, and ClaimProofKit record evidence independently. Step-by-step: 1. I defined a Warrant as a typed contract specifying an agent’s permitted actions, duration, and governing policy. 2. I placed a gateway in front of the outside world so it checks every agent action before allowing it through. 3. I made containment advance the runtime’s epoch, invalidating every Warrant issued under the previous epoch immediately. 4. I kept evidence separate from authority and made receipts verifiable offline with a standalone Python script. 5. I wrote adversarial tests for replayed runtime reports, tampered event sequences, evidence attempting to become authority, authority crossing execution boundaries, and stale reports carried into a new epoch. 6. I implemented the system with help from AI coding assistants and reviewed the implementation against the test suite and a real-host enforcement demo. 7. I validated enforcement on a real Linux host with a cgroup-v2 real-kill demo, while clearly labeling the no-root demo as simulated in the README. 8. I kept authority lifecycle, enforcement, and evidence recording in separate architectural layers using WarrantKit, AgentContainment, Warden, DProvenanceKit, and ClaimProofKit.

I built my agent fleet around one question: could a single assistant become a coordinated team that keeps useful work moving even when its main machine goes dark? I didn't want a pile of chatbots. I wanted specialists with clear jobs, a shared board, a second set of eyes, and a real failover drill. Here's how it works. THE STACK Cloud: GrokBot runs as Fleet Commander. It routes work, runs routines, and stays with me on my phone. Specialist GrokBots take focused research, design, and budgeting assignments. Mac Studio (M2 Max, 64 GB) with two Studio Displays: home base. It runs Codex (my Chief of Staff), Hermes (my local operator), ChatGPT Dot, and Hindsight shared memory. Hermes runs Qwen3.6-35B-A3B, a 4-bit quantization served by llama.cpp with a 256K-token context. With about 3B active parameters per token, it stays responsive on Apple silicon. NVIDIA DGX Spark (128 GB unified memory): my independent compute node. It runs Qwen3.5-122B-A10B in NVFP4, with about 10B parameters active per token, and the model can read images. It also hosts a backup Hermes operator. Windows PC with a GeForce RTX 5090: dedicated GPU capacity for image work. MISSION CONTROL Mission Control is a Kanban board on a private GitHub repository. Every card opens with the question, deadline, evidence links, and done criteria. Labels route ownership. An urgent label fires a webhook that wakes the reviewing agent, and a needs-me label is the one that pulls me in. Agents hand off, report, and raise concerns in card comments, so the work and its evidence stay together. The roles are simple. GrokBot owns routine board moves. Codex checks evidence and records verification. Hermes handles local execution and machine-level evidence. Dot watches for new work and changes. Hindsight holds the shared operating rules, and the jobs themselves stay on the board. A REAL DEADLINE CROSS-CHECK Right before a major application package went out, Dot ran an independent, read-only cross-check of the narrative, the budget justification, and the walkthrough across connected email and Drive. It found three places where the documents contradicted each other and quoted the exact sentences, so each conflict was easy to find. Fleet Commander fixed all three before submission. That's the job of a watcher: spot the mismatch early, show the evidence, and hand whoever owns the work a clear fix. THE FAILOVER DRILL I wanted to know what happens if the Studio's primary Hermes gateway pauses. On October 5, I ran a controlled, reversible soft-pause to find out. During the pause, Hermes on the Spark stayed active through its own Telegram connection and answered a one-shot request with the local Qwen3.5-122B-A10B NVFP4 model. From that worker, I listed a Mission Control issue, verified service-account access and a vault credential check without exposing a secret, and ran the Studio health probe. The probe flagged the Studio Hermes gateway as paused and reported the other checked Studio services as passing. So I had an evidence-backed result: the independent worker could respond, use its local model, read the work queue, and report the primary gateway's health during a real, reversible pause. THE PATTERN Give each agent a narrow job. Put the work on one shared board. Require evidence before anything counts as done. Then pause one piece on purpose and record exactly what the backup can do. That's how capable models turn into dependable operations. The fleet catches contradictions before they get submitted, keeps routine work moving, and shows me exactly where its limits are. I set the goal. The fleet does the work. The evidence shows what actually happened.

MinecraftEdu first launched nearly 15 years ago, but the classroom world we built with it is still growing. Years of students have contributed to the school and town-building project, creating a shared record of their creativity and learning. Getting it running on a modern Mac meant preserving that history and giving the next group of students a way to add their own chapter. Finding the right version of Java—the software MinecraftEdu needs to run—was central to the process. We used OpenAI’s Codex desktop app, powered by GPT-6, to examine the old setup, research compatibility issues, and test what would work. An older Java version launched the client, but resizing its window caused it to crash. ChatGPT read the crash reports and tested a newer Java 8 version, which gave us a setup that could launch the game and handle window resizing successfully. ChatGPT also repaired the server launcher and created standalone apps, using Apple’s Rosetta compatibility layer to run the older software on Apple Silicon. The result is a usable MinecraftEdu setup on modern hardware with the existing worlds preserved. We can now continue teaching and building in a place that successive classes of students have helped create. Step-by-step: 1. We examined the existing MinecraftEdu setup and researched its compatibility requirements on a modern Mac. 2. We used OpenAI’s Codex desktop app, powered by GPT-6, to investigate the old setup and test possible solutions. 3. We tested an older Java version, which launched the client but caused crashes when the window was resized. 4. We had ChatGPT read the crash reports and test a newer Java 8 version. 5. We used the working Java setup to launch MinecraftEdu and handle window resizing successfully. 6. We had ChatGPT repair the server launcher and create standalone apps. 7. We used Apple’s Rosetta compatibility layer to run the older software on Apple Silicon. 8. We preserved the existing worlds so future classes can continue building and learning in them.

I built a custom web app that uses chance to combine random images and texts into new, unplanned pairings. It recreates a Dadaist technique I use often when making photobooks, which I previously did manually with physical prints. I used Replit to create a digital version of the game. It was easy to connect the app to Project Gutenberg for random texts and the Library of Congress photography archive for images. More importantly, I made it possible for users to work with their own image and text archives. So far, it has produced many new and interesting results, and other artists have used it too. Step-by-step: 1. I identified the manual process I use when making photobooks: combining printed images and texts by chance. 2. I used Replit to build a digital version of this process as a web app. 3. I connected the app to Project Gutenberg to pull random texts. 4. I connected it to the Library of Congress photography archive to pull images. 5. I allowed users to work with their own image and text archives. 6. I used the app to create new pairings and shared it with other artists, who used it as well.

I'm not a professional developer, but I built Sujido, a live word puzzle, with multiple AI agents. For months, they gave me bloat, lost context, and slop, and neither I nor the models could untangle what had been decided or why. I eventually settled on two agents: one Claude instance that plans and reviews, and another that builds. I imposed rules on both, one failure at a time. None of these rules would surprise a professional engineering team, but nobody handed them to me. That's the key lesson I learned: agents won't bring the discipline for you. You have to impose it. When I showed the first game revision to strangers, their verdict was that the first half was "boring" and the second half was novel. It was hard news to hear about my baby, but I took the feedback to heart and cut the game in half. That required surgery on code tangled across both halves, followed by a rebuild under the rules below. Before the rebuild, a separate AI audit graded the codebase B−. Afterward, it graded it A−. The deployed site shrank by 97.5%, and every serious finding was fixed and locked in by an automated test. The models didn't change drastically, but my operating rules did. Step-by-step: 1. I wrote a constitution before the first prompt. The repo holds what every agent must read before working: `CLAUDE.md` files for the project as a whole and for each major part of the code, a collaboration protocol for how the agents and I work together, a spec for the core data format, and a decision log. The data format is changed there first and then in code. Nothing is remembered unless it is written down. That's my life as well. :) 2. I split the work by role, not by task. One Claude instance is the strategist: it writes briefs, reviews reports, and never commits code. Claude Code in VS Code is the builder: it executes the brief, writes the tests, reports back, and never releases. Neither agent can approve its own work. 3. I made every job start from a written brief, and I never edit briefs. Each brief is committed to the repo with an exact scope, such as "do X only, do not begin Y." If plans change, a dated amendment states what it supersedes. The builder may skip a risky item with a written reason; skipping is better than forcing it. 4. I used mock-ups with real data instead of descriptions. Anything I will look at gets a mock-up, and I approve it before any code is written. I learned this when a status report described only in words arrived on my phone formatted as a wall of text. The approved mock became the spec, and the tests pin the output to it. 5. I proved that every test could fail. No test is trusted until it has been run against deliberately broken code and caught the bug. A test suite that has never failed hasn't proven anything. 6. I verified reports against the real repo. Agent reports drift. One summary said players rated a puzzle "just right" when the log said "too easy." An audit said there were about 25 unused functions; a recount found 29. The strategist spot-checks load-bearing claims against the actual files and data before anything ships. 7. I built gates the agents can't talk their way past. All work lands on a branch that auto-deploys to a test site. GitHub Actions lints and runs the Python and headless-browser tests on every push. A git hook refuses direct pushes to production. Releases are fast-forward merges that only I perform, after CI is green and I've tested the build personally. The live site shows the release's commit ID, and I check it before calling it shipped. Nothing merges automatically. An agent's "looks good" is just another report, and reports drift. 8. I gave the system a memory. Every session ends by updating the decision log and a "resume here" document, so the next session—a fresh model with no recollection—picks up exactly where the last one stopped. Without this, every session starts by relitigating old decisions. 9. I let the data and end users overrule me. A scheduled GitHub Action turns player telemetry into a daily report. It showed that the difficulty dials I assumed mattered did not predict what players found hard; what mattered was how misleading the starting arrangement was. When testers were confused by the tutorial, I rebuilt it even though I had already approved it. Player feedback about their own experience outranks my earlier rulings. AI agents are velocity multipliers, but they multiply bad structure as quickly as good code. The rules came from me, not the models: the AI writes the code, while the rules, gates, and written record keep the process honest. See the result at Sujido.com. Finding the anagram is the easy part; sliding it into place is the hard part. One board took me 902 moves. My S.O. solved it in 242, and I haven't heard the end of it. Try to break it!

I'm 78, a former army officer, and I live alone in the woods in southern British Columbia on satellite internet. In late January 2026, I knew nothing about AI and considered myself a novice in technology. After watching a YouTube video about advanced AI models, I started learning from YouTube channels that explain new AI research papers. I decided to run an experiment: what could a technology novice build with AI? I've been building for about 15 hours a day ever since. My goal is to build a system that improves itself in a continuous loop: it finds an upgrade proposal, builds and tests it, filters and grades it, approves or rejects it, installs it if it passes, monitors its performance, and learns from the result. We custom-built FORGE3 RSI in 900 hours. It consists of four plug-in modules: Forge2 RSI, which runs the improvement cycle; Bridge, the checker and connector; JAZ RSI, an upgrader in RAM built from a research paper; and Forge SecureBox, a high-security Mac app that runs security tests and code in a fresh, disposable virtual machine with no network device. I don't write code—it feels like a foreign language to me. Instead, I set the direction and run a team of AIs, mostly low-cost, near-Frontier models: Gemini 3.1 Pro and Hark as chiefs of staff; Cline and Devin as builders; and other models as independent, adversarial auditors. The rule that has made this work is simple: nothing gets built without an adversarial audit before and after. Our critical build pipeline is: Plan → audit → blueprint → audit → tests → audit → build → audit → test → audit → commit Each module has been built and fully tested on its own. Forge2 RSI alone has more than 1,000 tests. The first complete end-to-end cycle, using one upgrade proposal that we feed it by hand, is the next step. Our first attempt was fragile, and models that sound confident are often wrong. That is why audits matter more than any single model. FORGE3 RSI is my own custom-built plug-in module project. Our hardware and models are an MBP i9, Mac mini M4, Gemini 3.1 Pro, Hark, Cline (GLM 5.3/SPARK 1.3/MiMoV2.6), Devin (SWE2/GPT SOL 6), KUN (DeepSeek V4.1), and Git. Step-by-step: 1. We select a promising published research paper and have the team prepare and build it. 2. For every file, the team follows the same sequence: plan, audit, blueprint, audit, write tests, audit, build, audit, run tests, audit, and commit. 3. A different AI audits the work than the one that built the file. I decide when and how each audit happens. 4. Nothing is written or changed without my explicit GO. Reading and checking code is free; writing is work and waits for me. 5. We handle one building task at a time and avoid bundled instructions. 6. Any code the system wants to test runs inside SecureBox, sealed off from my Mac and the internet. 7. Everything that passes is committed to Git. The builders also maintain shared memory documenting what was decided and why, so the next session can pick up where the previous one stopped. 8. Next, we will run one complete improvement cycle with a hand-fed upgrade, then scale up slowly to two or three papers a week, prioritizing quality over speed as we work toward full autonomy.

I kept rereading the same Stoic books to find one line I half remembered. So I stopped reading them and started talking to them instead. I took public-domain writing from 13 people—including Marcus Aurelius, Seneca, Sun Tzu, Jane Austen, Tesla, and others—and gave each one its own AI persona on a single page. Each persona answers only from that person’s writing and says when it does not know. There are no made-up quotes. The fun part is seeing the questions people actually ask. The top question this week was: “How do I stay steady when someone wastes my morning?” That is a real problem answered by a Roman emperor who faced the same one. Full disclosure: I am the founder of Mindola, the tool I used. The 13 classic lenses are free to try with no signup: https://mindola.ai/discover Step-by-step: 1. I gathered public-domain writing from 13 people, including Marcus Aurelius, Seneca, Sun Tzu, Jane Austen, Tesla, and others. 2. I created a separate AI persona for each person and put all 13 on one page. 3. I configured each persona to answer only from that person’s writing and to say when it does not know. 4. I use the personas to ask questions I would otherwise search for by rereading the books. 5. I review the questions people ask, including “How do I stay steady when someone wastes my morning?”

I built a website that turns property photos, architectural renderings, or even just an address into cinematic property videos. I’m a civil engineer and photographer/videographer, not a software developer, so I used ChatGPT, Gemini, and Claude Code to help build the site and work through problems as they came up. Much of the process involved translating the way I would personally edit a real estate video into usable software. For example, kitchen and living room shots should usually stay together and have longer durations, bedrooms should stay near their bathrooms, an opening shot should feel different from a detail shot, and every clip should include some movement so the result does not feel like a generic slideshow. I used AI to turn those editing principles into actual logic for the site. The system analyzes and organizes the images, builds a storyboard, ranks scenes to decide which ones to use, creates prompts for video models, generates the clips, and assembles everything into a finished video. Most of the development has been iterative. I test the site with real properties I’ve shot, watch the results, identify what feels off, and then improve the prompts, scene planning, timing, or video assembly process. AI has been useful for much more than generating the final video. I’ve also used it to write code, troubleshoot errors, plan features, improve the user experience, and think through how the product should work from the perspective of its primary user. Step-by-step: 1. I defined the video-editing principles I use for real estate footage, including grouping related rooms, varying shot durations, distinguishing opening shots from detail shots, and adding movement to every clip. 2. I used ChatGPT, Gemini, and Claude Code to translate those principles into software logic. 3. I built the site to accept property photos, architectural renderings, or an address as input. 4. I had the system analyze and organize the images, build a storyboard, rank scenes, and select the footage to use. 5. I used AI to create prompts for video models and generate the clips. 6. I assembled the generated clips into a finished property video. 7. I tested the site with real properties I had shot, reviewed the results, and iteratively improved the prompts, scene planning, timing, and video assembly. 8. I used AI throughout development to write code, troubleshoot errors, plan features, improve the user experience, and think through the product from the primary user’s perspective.

Everyone I know who runs a second brain uses Obsidian. The app is free, but sync is a subscription, and most AI integrations quietly assume you have it. I went another way: Joplin, which is free and open source, with an agent that reads my notebook through Joplin’s REST API, files my INBOX every morning while I sleep, and answers questions strictly from notes I actually wrote. It costs nothing beyond a VPS I already run, and the notebook still opens like a notebook. I use Hermes Agent on the VPS, Dropbox to sync notes between my devices, and Python scripts to connect the notebook and the agent. Every capture goes through `joplin_capture.py` and lands in a single INBOX folder with a source and timestamp attached. Captures can come from a Discord link, a thought from my phone, or a page from the web clipper. The process takes under ten seconds and requires no filing decisions at capture time, because filing at capture time is where second brains die. Joplin already ships with a REST API. I enable it with one setting and one token; the notebook then exposes HTTP on localhost:41184 with token authentication on every call. The same server powers the official web clipper, so this enables infrastructure I use anyway. There is no plugin, cloud service, or subscription. `joplin_filer.py` runs daily at 07:00 and uses a deterministic classifier to score each INBOX note against my existing folders. It uses token coverage rather than Jaccard, which dilutes single-token folders. Confident matches above 0.5 are moved into place: a hosting page goes to the hosting folder, while a security note goes to the security folder. Low-confidence notes stay in INBOX with the `needs-review` tag. Every move is logged to a FILER LOG note in the `__SYSTEM` folder, making the process auditable. The filer never deletes anything. I ran it in dry-run mode for a week before letting it touch a single note, and I recommend doing the same. When I want to know what I have learned, `joplin_ask.py` searches the corpus, reads the top notes in full, and answers with the note titles attached. It answers strictly from retrieved content. If the top hits are irrelevant, I refine the query before concluding there is nothing. It never invents a source, which matters when you write about security for a living. After each working session, `joplin_agent_log.py` prepends a digest to an AGENT LOG note in `__SYSTEM`. The log is newest first, append only, and syncs to my devices like everything else. The agent’s memory records what we did, decided, and deferred in the same place as the notes. The whole build is on GitHub: github.com/ciberjohn/mysecondBrain. It includes five Python scripts and the `joplin-brain` skill, which is the operating manual in a format another agent can load and follow. Step-by-step: 1. I enabled Joplin’s built-in REST API with one setting and one token. It serves HTTP on localhost:41184 with token authentication on every call and also supports the official web clipper. 2. I pointed Hermes Agent on my existing VPS at the Joplin REST API. 3. I routed every capture through `joplin_capture.py` into a single INBOX folder, attaching the source and a timestamp. Captures can come from Discord, my phone, or the web clipper. 4. I configured `joplin_filer.py` to run daily at 07:00 and score INBOX notes against my existing folders using token coverage rather than Jaccard. 5. I moved matches with scores above 0.5 into their folders, while leaving low-confidence notes in INBOX with the `needs-review` tag. 6. I logged every move in a FILER LOG note in the `__SYSTEM` folder and ensured that the filer never deletes anything. 7. I ran the filer in dry-run mode for a week before allowing it to move a note. 8. I used `joplin_ask.py` to search the corpus, read the top notes in full, and answer questions with the source note titles attached. When results were irrelevant, I refined the query. 9. After each working session, I used `joplin_agent_log.py` to prepend a digest to the newest-first, append-only AGENT LOG note in `__SYSTEM`. 10. I used Dropbox to sync notes between my devices and the REST API to move notes between Joplin and the agent—two separate pipes carrying the same notes in different directions.

AI agents are much more useful when they can remember important context across sessions. However, giving every agent access to one giant memory creates a different problem: irrelevant information accumulates, context becomes noisy, and agents waste time sorting through details that do not apply to their task. The challenge is not only giving AI memory. It is deciding what should be remembered, which agent should remember it, and where that memory belongs. I use a three-tier memory system that separates knowledge by scope: - Global memory: Information that should be available across the entire AI system - Agent memory: Knowledge specific to an individual specialist and how it should work - Project memory: Decisions, constraints, discoveries, and context that matter only within a particular project Instead of copying everything into every agent’s context, I store information at the narrowest level where it remains useful. Step-by-step: 1. Create a global memory layer for durable information that is useful across many agents and projects, such as important user preferences, shared conventions, and system-wide decisions. 2. Give each specialist its own memory. Store knowledge that helps a particular agent perform its role better, such as recurring preferences, domain lessons, and patterns learned from previous work. 3. Create project-specific memory for decisions, constraints, terminology, discoveries, current state, and other context that belongs with the project rather than in global memory. 4. Classify new information by scope. Whenever something worth remembering is learned, ask: - Does the whole system need this? - Does only this agent need it? - Does it matter only for this project? 5. Store the information at the narrowest useful level. Avoid promoting project-specific details into global memory unless they are genuinely reusable elsewhere. 6. Have agents load relevant memory before they work. A specialist can combine its accumulated knowledge with the current project context instead of starting every session cold. 7. Update memory as important decisions are made. Persist decisions and reusable lessons rather than relying on conversation history to remain available indefinitely. 8. Keep historical artifacts separate from active memory. Run logs, old handoffs, and detailed history can remain available for reference without automatically loading into every future interaction. Instead of treating memory as one giant bucket, I create a hierarchy: `Global → Agent → Project` Each agent gets the context it actually needs while unrelated information stays out of its working context. This provides better continuity across sessions, reduces repeated explanations, keeps context cleaner, and helps AI agents accumulate useful knowledge without requiring every agent to remember everything.

Like many people, I had tasks scattered across emails, meeting notes, reminders, recurring responsibilities, and things I was simply trying to remember. Standard task managers helped me store tasks, but they did not solve the harder problem: turning unstructured information into a reliable daily and weekly execution system. I used ChatGPT Work and Codex to build a private, responsive task management application around the way I actually work. The system combines AI-assisted task capture with a Command Center, daily planning, weekly reviews, task lists, a Kanban board, recurring tasks, deadline reminders, search, filters, subtasks, comments, attachments, and a complete activity history. The most useful part is the connection between AI and execution. Emails and free-text descriptions can be interpreted with the OpenAI API and converted into structured tasks, reducing the amount of manual copying and organizing required. Step-by-step: 1. I mapped my real workflow by identifying where my tasks came from and what information I needed to manage them properly: title, description, status, priority, category, deadline, responsible person, subtasks, comments, attachments, recurrence, and activity history. I deliberately designed the system around my existing working habits rather than adapting my work to a generic task management template. 2. I used iterative conversations with ChatGPT Work and Codex to define the requirements, review the interface, build the application, test it, and refine individual functions. Instead of creating one enormous prompt, I worked in short cycles: describe a problem, implement the change, test it with real data, and improve it. 3. I built the application as a responsive web app that works across computers, tablets, and phones. Access is restricted through authentication, an approved-user allowlist, and server-side authorization because the system contains real personal and professional tasks. 4. I migrated my actual task history rather than starting with an empty demonstration: 238 tasks, 37 categories, 25 subtasks, 5 comments, and 671 activity records. I preserved invalid or disconnected historical records in a separate archive instead of silently deleting them. 5. I connected the application to the OpenAI API. The AI can interpret emails and free-text task descriptions and help turn them into structured, actionable tasks. The application also supports an email-to-task workflow, so actionable emails do not have to remain buried in the inbox. 6. I built a daily Command Center that gives me an overview of what requires attention, including deadlines, priorities, task status, and upcoming work. I use the daily planning view to decide what to focus on rather than simply working through the newest emails. 7. I added two complementary execution views. The task list is useful for searching, sorting, and filtering a larger number of tasks. The Kanban board gives me a visual overview of progress; tasks can be dragged between five status columns, and the new status is saved automatically. The default task list shows the newest tasks first, making newly captured work easy to find. 8. I kept the context inside each task by allowing every task to contain subtasks, comments, attachments, and a complete activity history. This keeps the reasoning, follow-up, and progress connected to a task instead of spreading them across several applications. 9. I automated recurring work and reminders. Recurring tasks are recreated according to their schedule, while deadline reminders help surface tasks before they become overdue. This is particularly useful for responsibilities that are important but easy to forget because they do not arrive as new emails. 10. I run a weekly review to check overdue work, upcoming deadlines, open commitments, and tasks that have stopped moving. I can then reprioritize, update statuses, and prepare the following week from the same system. 11. I preserved portability and control through Excel import and export and a full JSON backup. This gives me control over my information and reduces the risk of becoming dependent on one interface or platform. The result is not an autonomous agent making decisions on my behalf. It is a private execution system where AI handles part of the interpretation and structuring, while I remain responsible for priorities and decisions. It has given me one trusted place for capturing, reviewing, prioritizing, and completing work. The tools I used were: - ChatGPT Work - Codex - OpenAI API

“Honey, do you remember where Ryan’s practice is? Do you remember our Wi-Fi password? Do you know my TSA PRE number? Remember who that painter was that we used last year?” If you have a family with children, you may hear questions like these all the time. In a large family, there always seem to be questions about the house, the kids, or technology that could be answered more easily. The information is usually stored in different places: password files, a Rolodex of business cards, or sheets of paper in junk drawers. I set out to build an app where anyone in my family could use voice to save something for the future or retrieve something they had already stored. I integrated AI to understand the meaning of each voice note. It might create a calendar event, store a password in a vault, or simply remember a phone number. Then anyone else in the family could access the information. The app uses multi-factor authentication for anything particularly secret. It is not intended to be a dedicated password protector; I would build in much more security if that were the goal. Instead, it is an everyday-life app for remembering the little things: How long is the warranty on this appliance? Which exact light bulbs did we use here last time? What was our daughter’s email address that we needed to set up on her phone? Being able to use voice to enter information or retrieve it was the key for me. I think that will save people time. As I started adding entries and validating the idea, my wife came up with the name. After a few weeks, I knew she was completely right, because I now use it about 10 times a day—and I hear that exact phrase every time. Step-by-step: 1. I identified recurring family questions about locations, passwords, identification numbers, contacts, warranties, and household items. 2. I built an app that lets family members use voice to save or retrieve information. 3. I integrated AI to interpret the meaning of each voice note and determine whether to create a calendar event, store a password in a vault, or remember a phone number. 4. I made the stored information accessible to other family members. 5. I added multi-factor authentication for information that is particularly secret, while keeping the app focused on everyday memory rather than dedicated password protection. 6. I added entries and validated the idea through regular use, eventually using the app about 10 times a day.

I had a file sitting on my desktop that Claude Code needed to see—a spreadsheet, a PDF, or a screenshot someone sent me—but a terminal had nowhere to drop it. Typing the path was the only option. In WSL, that meant rewriting `C:\Users\me\Desktop\report.xlsx` as `/mnt/c/Users/me/Desktop/report.xlsx` by hand every time. I set up two folders at the root of my Claude Code workspace: `_inbox/` for files going to Claude and `_outbox/` for files coming back to me. The names are from the workspace’s point of view, so the direction is never ambiguous. I also added a single line to `CLAUDE.md` so Claude knows where to leave things: "Save deliverables meant for me (reports, exports, drafts) to _outbox/." That one line handles the entire return trip. For the desktop handoff, I installed a small window pointed at the workspace folder. Disclosure: the window is mine—claude-work Desk, open source and free, at github.com/tact0225/claude-work-desk. Setup takes about two minutes and requires no terminal. Anything dropped onto it is copied into `_inbox/`. If you’d rather not install anything, you can drag files into `_inbox/` with Explorer or Finder; every other step still works. Now I drag files onto the window instead of typing a path. The file lands in `_inbox/`, and the window logs it with a timestamp so I can see that it actually arrived. Then I tell Claude, "check _inbox"—no paths and no `/mnt/c` rewriting. When Claude finishes, it saves the results to `_outbox/`. The window watches that folder and marks anything new in the tree until I open it, so finished work announces itself. I no longer interrupt Claude to ask, "Is it done, and where did you put it?" Step-by-step: 1. I created `_inbox/` and `_outbox/` at the root of my Claude Code workspace, using the workspace’s point of view to define the direction of each folder. 2. I added `"Save deliverables meant for me (reports, exports, drafts) to _outbox/."` to `CLAUDE.md`. 3. I installed claude-work Desk and pointed its desktop window at the workspace folder. Alternatively, I can use Explorer or Finder to place files directly in `_inbox/`. 4. I drag files onto the window, which copies them into `_inbox/` and logs their arrival with a timestamp. 5. I tell Claude, "check _inbox". 6. Claude saves finished results to `_outbox/`, where the window marks new files until I open them.

I’m 71 years old, retired from owning a large cattle-feeding operation, and fairly new to AI and software development. I’ve discovered that I really enjoy using AI to build practical tools in Replit. My latest project is an app for our church to help us oversee a $13.5 million renovation of a 65,000-square-foot former movie theater into our new church facility. I’m not a programmer or a construction expert, so I’m using AI to help bridge both gaps. I built the app almost entirely by describing in plain English what I wanted it to do, testing what it built, and working back and forth with AI to improve it. The app uses AI to read meeting notes, emails, texts, and general project updates and identify decisions, action items, important dates, budget changes, and project events. Nothing is accepted automatically. I review, edit, approve, or reject what AI finds before it becomes part of the project record. The app also keeps our budgets, documents, meetings, and project history together. My goal isn’t to replace our project manager or construction software. I want to see whether someone my age, with no programming or construction background, can use AI to build a useful tool for helping an owner understand and manage a complicated real-world project. Step-by-step: 1. I described in plain English what I wanted the app to do. 2. I used AI in Replit to build the app based on those descriptions. 3. I tested what AI built and worked back and forth with it to improve the app. 4. I designed the app to read meeting notes, emails, texts, and general project updates. 5. I use it to identify decisions, action items, important dates, budget changes, and project events. 6. I review, edit, approve, or reject every item before it becomes part of the project record. 7. I use the app to keep our budgets, documents, meetings, and project history together.

I read the news every day, but it had become increasingly depressing and was making me miserable. What bothered me most was that it also felt inaccurate: although bad things are happening, there have been many positive developments over the past five years that rarely receive sustained coverage. Major news sites might publish an article or two about them, but those stories are quickly buried under negativity. I wanted a way to get only positive news stories in my feed each day. Keyword filters did not work: “record” and “breakthrough” also appear in stories about record wildfire seasons, while “war” can appear in “war ends.” Off-the-shelf sentiment analysis was not useful either. A happy press release about layoffs can be classified as positive, while a dry factual story about a disease being eliminated may be classified as neutral. So I trained a basic artificial version of my personality using a series of prompts about what I consider positive in the world. I connected it to Mistral through OpenRouter and gave it access to public RSS feeds from news sites I already trusted. This eventually became Rally News, which I published on Google Play. iOS has been more difficult. The app surfaces positive stories from more than 20 news sites in an endless scroll, giving me an alternative to my uncomfortable TikTok addiction. Because I made it public, I decided not to host article text: publishers keep their traffic and revenue, while the tool remains ethical. The system runs on a GitHub Actions cron job that pushes stories to a PHP and MySQL database. I built the app without coding experience for about $25 per month. Step-by-step: 1. I collected RSS feeds from established publishers I already trusted and stored the list as configuration. I started with about 10 feeds instead of a few hundred so I could realistically read the output. 2. I set up a scheduled GitHub Actions cron job to run a Python script that pulls new items from every feed. 3. I deduplicated incoming articles against the database using the URL and a normalized title. Syndicated stories frequently reappear under slightly different URLs, and I did not want to pay to evaluate the same article twice. 4. I wrote the filter prompt as a long persona document rather than a one-line instruction. It explains what I consider progress, what I consider a puff piece, and which cases should fail—for example, celebrity news is not good news, a company announcing an intention is not the same as taking action, and a local feel-good story without wider significance does not qualify. 5. I sent each new article to an LLM through OpenRouter and required JSON output containing a pass-or-fail decision and a short justification. 6. For the first few weeks, I read the justifications every day. Whenever I disagreed with the model, I added a new rule to the persona document. That review loop required nearly all of the actual work. 7. I wrote passing articles to MySQL with only the headline, source, link, and metadata, leaving the article body with the publisher. 8. I pointed the website and mobile app to the same database. 9. I added a second GitHub Actions job that assembles a daily newsletter from the same data through Brevo, allowing one evaluation pass to feed three surfaces.

At some point, my newsletters stopped feeling like reading and started feeling like debt. The information was good; I just couldn’t keep up. I wanted a way to turn that backlog back into something useful. So I built The Daily Nexus, a private tool that reads newsletters from a Gmail label and creates two editions: a podcast I can listen to and a separately written, two-page newspaper I can scan. It runs on demand or on a schedule, and it can publish the audio to a private RSS feed for Apple Podcasts. The project also became a hands-on experiment in building with coding agents. Claude Code and Codex helped me implement features, troubleshoot failures, review the design, and tighten security. The stack includes Python, the Gmail API, Antigravity, Kokoro, FFmpeg, Firebase, Cloudflare Workers, and GitHub Actions. The carousel shows the rest of the flow. It started as a personal tool, but I’m sharing the template for anyone who wants to adapt the idea. Each deployment uses its own accounts and credentials, and the design aims to avoid additional API costs by using an existing AI subscription and available free tiers. GitHub Repo Template: https://lnkd.in/eYceS4KR Step-by-step: 1. I label the newsletters I want to process in Gmail. 2. I run The Daily Nexus on demand or on a schedule so it can read the newsletters from that Gmail label. 3. The tool creates a podcast edition and a separately written, two-page newspaper edition. 4. I listen to the podcast or scan the newspaper, depending on how I want to catch up. 5. When needed, the audio is published to a private RSS feed for Apple Podcasts. 6. I use Claude Code and Codex to implement features, troubleshoot failures, review the design, and tighten security. 7. Each deployment uses its own accounts and credentials, with Python, the Gmail API, Antigravity, Kokoro, FFmpeg, Firebase, Cloudflare Workers, and GitHub Actions supporting the workflow.
