Tree of Thoughts was a genuine leap. Instead of reasoning in one straight line, it branches into several lines, scores them, prunes the dead ends, and searches for the best path — so a puzzle that would sink a single chain of thought becomes solvable. But a tree has one restriction baked right into its shape, and once you see it you can't unsee it: every node has exactly one parent. A branch can be extended or abandoned. It can never be combined with another branch. That matters more than it sounds. Real problems decompose, and when they do, different branches each get part of the answer right. Branch A nails the first half; branch B nails the second half; neither is fully correct on its own. A tree is forced to pick one and throw the other's good half away. Graph of Thoughts (GoT) removes exactly that restriction. 🕸️ Interactive demo (a real merge-sort that branches, merges, and refines — with live-verified scores): https://dev48v.infy.uk/prompt/day21-graph-of-thoughts.html The core idea: thoughts are nodes in a graph GoT reframes reasoning as building a graph . Each vertex is a thought — a partial solution or intermediate result. Each edge is an operation that produced one thought from one or more others. Because it's a general graph and not a tree, a thought is allowed to have several parents, and edges can even loop back on themselves. That single change in the data structure is the entire conceptual leap. Everything else is just the operations you're now free to run on that network. The four operations generate (branch) — the familiar move, straight from Tree of Thoughts. From one thought, produce several different next thoughts. This can also be a split : break the input into independent sub-problems solved on separate branches. Diversity matters here — near-duplicates waste budget. score / rank — turn each thought into a number so the controller can compare them. Objective scorers win: a validator, a test, a metric. In the demo, the scorer is deliberately con

Cassie Shum discusses the architectural evolution of GraphRAG and why data foundations are critical for advanced AI workflows. She explains how traditional vector RAG falls short when addressing global context, multi-hop reasoning, and provenance. She shares enterprise strategies for building semantically structured knowledge graphs that shift raw orchestrating logic down to the data layer. By Cassie Shum

Meta is developing plans for a cloud infrastructure business, selling access to AI compute power and models. The move would pit it against the big cloud providers like Amazon Web Services, Google Cloud, and Microsoft Azure.

Contorium is a local-first system that introduces persistent project cognition into AI-assisted development workflows. Instead of treating AI as a tool that operates on code, Contorium treats the project itself as a structured, evolving system. ⸻ 🧠 Problem Modern AI coding workflows suffer from a structural limitation: Even with tools like: Cursor Claude Code MCP-based agents IDE copilots context is still: fragmented session-based non-persistent weakly structured This leads to: repeated explanations, lost reasoning, and architectural drift ⸻ 🧩 Solution: Project Cognitive Runtime (PCR) Contorium introduces a runtime model where project understanding is persistent and structured. ⸻ Core Components ⸻ PIK — Project Intent Kernel PIK defines the system-level intent of a project: primary goal constraints non-goals priority weighting It acts as a stable semantic anchor. ⸻ CIL — Cognitive Interaction Layer CIL captures reasoning: why decisions were made what alternatives were considered how context influenced outcomes It makes reasoning persistent instead of ephemeral. ⸻ Timeline Layer All system changes are recorded as events: code changes AI outputs tool interactions architectural decisions This enables replay and evolution tracking. ⸻ Drift Detection Layer A continuous alignment system compares: current behavior vs PIK intent It detects: intent drift structural drift behavioral drift And produces measurable deviation signals. ⸻ 🔁 System Loop Contorium forms a continuous loop: PIK defines intent Execution produces behavior Timeline records evolution Drift system evaluates alignment Suggestions guide correction This creates a self-regulating project system. ⸻ 🧠 Key Insight Contorium is not an AI coding tool. It is a: Project Cognitive Runtime (PCR) A system where software projects maintain structured intelligence over time. ⸻ 🚀 Why it matters The bottleneck in AI development is no longer capability. It is continuity of understanding across: time tools agents sessions Conto

The goal is to start the day already briefed — not to spend the first hour becoming briefed. What follows isn't groundbreaking. It's just what pushing my own boundaries looks like in practice. The problem As a Tech Lead of a larger team, my mornings used to look something like this: open email, skim through multiple newsletters I subscribed to for staying current on AI and dev topics, switch to Slack, scroll through everything I missed, try to figure out what actually needs my attention, then check what code went into the repo in the last 24 hours. By the time I was done "catching up," a good chunk of the morning was gone. I knew there had to be a better way. Starting with Claude Cowork Claude's desktop app has a feature called Cowork, and within that, you can set up Scheduled tasks — automated tasks that run on a schedule. I set up two that run every morning: Newsletter digest: This one pulls in all the newsletters I received the day before and summarizes them for me, grouped by topic — AI-related first, then dev, then everything else. Instead of opening each email and scanning for what's relevant, I get a curated briefing in seconds. Slack summary: This gives me a full summary of yesterday's Slack conversations across channels, and more importantly, flags what actually needs my attention. No more scrolling through hundreds of messages trying to separate signal from noise. The only downside? The Claude desktop app needs to be open and running for these to kick in. It's not a dealbreaker, but worth knowing. I'll be honest — the idea wasn't entirely mine. When you set up a new Scheduled task in Cowork, a Daily Brief is literally the example they suggest. I just happened to already be poking around with something similar. A lucky coincidence. Taking it a step further with Claude Code One of the hardest parts of leading a larger team is keeping tabs on everything that changes in code. PRs get merged, features get shipped, bugs get fixed — and it's nearly impossible to

We need to have a serious talk about the Model Context Protocol. Everyone is losing their minds over "vibe coding" right now. You plug an MCP server into Cursor, Claude Code, or VS Code, tell the AI to fix a bug across three directories, and go grab a coffee while it spins up local servers, reads files, and executes terminal commands. It feels like absolute magic. But honestly? It's also completely terrifying. Maybe I’m just paranoid, but it seems like we’ve collectively skipped the part where we ask ourselves if giving a statistical text-prediction engine raw, unvetted access to our local machines is a good idea. Some security folks are already warning that we’re walking directly into a massive remote code execution crisis. Think about it. Most MCP servers run as local subprocesses. They inherit your exact user permissions. If you run your editor as an admin or with access to sensitive environment variables, so does the AI. And the real issue isn't that the AI will spontaneously turn evil. The issue is prompt injection. The Security Void in the Hype I spent some time looking through public MCP servers on GitHub recently, and the sheer lack of input validation is wild. Because developers are rushing to build cool tools, basic security hygiene has completely lagged behind. If an AI agent reads an untrusted string—like a malicious comment in a GitHub issue, an automated email, or a dirty record inside a database—it can easily be manipulated into executing an injection payload. The model doesn't know the difference between your system instructions and the data it's processing. It treats them exactly the same. What happens when a prompt injection tricks a standard filesystem MCP tool into looking for a file named ../../../../../../etc/passwd or pulling your private AWS keys? The tool just does it. It’s a classic path traversal vulnerability, except instead of a malicious hacker typing it into a web form, an automated agent is doing it because a piece of text told it to.

By the team at MailTester Ninja — a real-time email verification API that stores nothing. We verify a lot of email for a living. So we pointed our infrastructure at a representative panel of 50,000 of the world's most-linked domains and measured how email is actually configured in 2026 — MX providers, SPF and DMARC. Pure DNS, aggregate only, no personal data . Here's what the internet's mail setup looks like right now. Email is still (almost) everywhere 79.9% of these domains are mail-enabled (they publish MX records). Email isn't going anywhere. Authentication: adopted, but not enforced 75.8% publish an SPF record 64% publish a DMARC record …but only 22.6% actually enforce it with p=reject That last number is the real story. Of the domains that bother to publish DMARC, only 35.2% are on p=reject — the rest sit on p=none (37.2%, monitoring only) or quarantine (27.6%). Most of the web announces a policy it doesn't enforce. That's a deliverability and spoofing gap hiding in plain sight. Who runs the world's inboxes? Other / self-hosted — 32.6% Google Workspace / Gmail — 28.2% Microsoft 365 / Outlook — 22.5% Proofpoint — 5.5% Mimecast — 3.1% Tencent QQ — 2% Namecheap — 1.3% Cisco IronPort — 0.9% Self-hosted and the two hyperscalers (Google Workspace and Microsoft 365) dominate, but the long tail of providers is very real — which is exactly why deliverability is hard: every provider blocks, greylists and reputation-scores differently. Why we publish this We built an open, daily-updated dataset and a live dashboard because deliverability decisions should be based on data, not folklore. It's CC BY 4.0 — use it, cite it, build on it. Want to check a specific domain? Our free analyzer shows any domain's MX / SPF / DMARC in one click — no signup, nothing stored. Methodology: Live DNS scan (MX/SPF/DMARC).

Exhaust the enemy's strength without fighting. Weaken the strong by nurturing the soft. — The 36 Stratagems, " Wait at Leisure While the Enemy Labors " P flipped the business card over and wrote one letter on the back: P . Then P walked into the conference room. P didn't do opening lines. P doesn't have a name — not yet, not in this series anyway. But if you've read the earlier stories, you'd recognize the signature. The first story — P's own article got flagged as "low quality" by the company's AI moderation system. P dug into the internal API, pulled 347 flagged records — effective accuracy came out to 38%. More false positives than correct identifications. The second story — an AI payment gateway processing $2.8 billion. The CTO backed it with formal verification, claimed it was "mathematically bulletproof." P spent eight months quietly building an adversarial testing pipeline, and proved the gateway would approve illegal transactions. P won both times. P left zero fingerprints both times. After those two jobs, P stopped working for other people. This time, P got brought in as an independent evaluator. Two Companies, One Customer, Zero Questions The customer was a mid-sized industrial IoT firm called FirmCore . Their production-line gear had been running for almost a decade. The monitoring system was going down once a month, and management had finally had enough. They decided to bring in an AI monitoring platform. A good call — right up until they decided to run two vendors through POC at the same time and pick a winner. "We want to see who can actually cover our failure modes," the VP said in the meeting. "We've also brought in an independent evaluator." P was that evaluator. The two AI monitoring companies were MonitorAI and SentryWave . MonitorAI's pre-sales team went first, slides blazing with "99.3% fault coverage, validated across 3 manufacturing customers." SentryWave followed right behind: "99.7% coverage, 7-day deployment" — bigger numbers, bolder font.

4-Phase Orchestration: How 5 Universal Agent Skills Achieve YAML-Driven Rules + Composable Components + Graceful Degradation When you're hard-coding your 3rd scoring if-else, maybe it's time to ask: can I move the rules into YAML and let the business change config instead of code? The Problem: Why Do Agent Skills Keep Reinventing the Wheel? Every Agent developer faces the same dilemma — every business scenario rewrites a similar pipeline : Scoring: Extract features → Match rules → Calculate score → Generate report Complaints: Extract ticket → Cross-validate → Pinpoint root cause → Archive Querying: Understand intent → Build SQL → Execute query → Render chart The skeleton is identical. What changes is only the "content" at each step. Yet every team builds pipelines from scratch. teleagent-skills offers an answer: freeze the skeleton into 5 universal Skills with 4-Phase orchestration, and let business changes live in YAML config only .

Bringing the ideas I've been thinking about for months into life has never been easier, thanks to AI agents. The basic intuition is—give it a prompt, it builds the whole feature, the result looks good. Done. It takes only minutes to build the same thing that would've taken hours otherwise. Yes, I know, everyone's doing that. Right? The reason I'm opening like this is to point out what happened afterwards. I tried to use the search bar, and it fired a request on every keystroke. Wait, what? I didn't do that. Of course I'd add a debounce here. But the agent didn't. Why? I didn't ask it to. I said—build me a search bar, and it built me one that works; but I didn't say exactly what I wanted. Also, I noticed that the search button changes color on hover, but I'd already told it not to do that. The agent forgot, it hallucinated. What's missing then? What was missing was I did not provide the agent with the exact decisions to work with the feature; or did not provide a proper reference point to fallback to, to remediate the hallucination. In other words, I did not provide it with a proper spec. Hence, it took the hidden decisions itself; even though it pulled the feature off. This is the core problem that Spec-Driven Development (SDD) solves. The Hidden Product Decisions Your AI Agent Is Making For You Here's what happens when you describe something to an AI agent and it generates code: lots of decisions get made. Let's take the search bar implementation as an example. Does the filtering happen on the client or the server? Does the URL update so results are shareable? What does an empty query show? Everything, or nothing? I tend to miss nitty-gritty details while reviewing tons of AI generated code in a short amount of time. The code works, the UI looks right, I move on… Every one of those is a decision that belongs to my product. If I don't make the decisions consciously, the agent takes them based on whatever pattern shows up most often in its training data. Take that se

If you run a RAG system in production, you eventually hit a dilemma that has nothing to do with your model and everything to do with your cache. Cache the answers to save tokens and latency, and one day a source document changes — but your cache keeps cheerfully serving the answer it built from the old document. Nobody gets an error. The number is just quietly wrong. Cache nothing , and every single call re-retrieves the same chunks, re-reads them, and re-pays the full context bill to rebuild an understanding you already built five minutes ago for a nearly identical question. Stale or expensive. Most teams pick "expensive" because at least it's correct, then bolt on a TTL and hope. This post is about why the TTL doesn't save you, and about two specific, mechanical fixes that let you cache RAG context and stay fresh. I maintain an open-source library called Coalent that implements both, so I'll use it for the runnable examples — but the two ideas are portable and worth stealing even if you never pip install anything. Failure mode 1: the stale RAG cache (and why a TTL won't save you) Here's the standard "answer cache" sitting in front of retrieval: answer = cache . get ( query ) if answer is None : chunks = retriever . retrieve ( query ) answer = llm . synthesize ( query , chunks ) cache . set ( query , answer , ttl = 3600 ) return answer This works until billing.md changes. The refund window goes from 30 days to 14. Your cache has an answer keyed on "what is our refund policy?" that says 30, and it will keep saying 30 for up to an hour — or forever, if the same question keeps refreshing a TTL that never expires under load. The reason this is hard is that the cache key (the query) has no relationship to the thing that changed (the source). You cached an answer; you threw away the fact that this particular answer was derived from billing.md . So when billing.md changes, you have no way to find the answers that depended on it. The TTL is a confession that you can't answ
